What Can Go Wrong With Kyphoplasty or Vertebroplasty? Cement Leaks and Symptoms to Report

The consent form sits on the kitchen table next to a cold cup of tea. Two weeks ago, a woman in her seventies bent to lift a bag of potting soil and felt something in her mid-back give way. The X-ray showed a vertebra squashed into a wedge. Now her spine team has offered a procedure that involves injecting cement into the bone, and the line that keeps catching her eye reads: cement leakage, nerve injury, pulmonary embolism.

Nobody on the team is trying to frighten her. Those words appear on every kyphoplasty consent form because they describe things that can genuinely happen. The trouble is that a list of complications, read alone at a kitchen table, gives no sense of scale, mechanism, or what to actually watch for once the bandage comes off.

This explainer aims to fill that gap: what kyphoplasty complications look like from the inside, why cement behaves the way it does, and which symptoms deserve a phone call rather than a wait-and-see.

What kyphoplasty and vertebroplasty actually do inside the bone

Both procedures treat a vertebral compression fracture, which is a break where the front of a spinal bone collapses because it has lost strength, most often from osteoporosis, a condition in which bone becomes porous and brittle. The goal is to stabilize the broken bone so it stops shifting with every breath and step.

Vertebroplasty is the older technique. A physician passes a hollow needle through the skin of the back, guided by live X-ray, into the fractured vertebra. Liquid bone cement, an acrylic material called polymethylmethacrylate, is pushed through the needle. It flows into the tiny gaps in the crushed bone and hardens within minutes, forming an internal cast.

Kyphoplasty adds one step. Before the cement goes in, a small balloon is inflated inside the vertebra to push the collapsed bone back toward its original height and create a cavity. The balloon is removed, and thicker cement is placed into that cavity under lower pressure. The word comes from kyphosis, the forward rounding of the upper back that compression fractures worsen.

That single difference, a cavity filled with thicker cement at lower pressure versus liquid cement forced into crushed bone, explains much of why the two procedures have slightly different complication patterns. Cement under high pressure finds every crack. Cement poured into a pre-made space tends to stay put.

Both are usually done under local anesthesia with sedation, or occasionally general anesthesia, and take under an hour per treated level, according to descriptions from major academic medical centers. Patients typically lie face down throughout, a detail that matters later when we discuss rib and positioning injuries.

Who is usually offered kyphoplasty, and who is asked to wait

Cement augmentation is not the first move for most compression fractures. Guidance from bodies including the National Institutes of Health describes conservative care as the starting point: a short period of relative rest, pain management, gradual return to walking, and treatment of the underlying osteoporosis. Many fractures settle this way.

Spine teams tend to consider kyphoplasty or vertebroplasty when pain remains severe enough to prevent walking or sleeping after several weeks of conservative care, when imaging confirms the painful vertebra is the recently fractured one, and when the person cannot tolerate the medicines or bed rest that conservative care requires. Older adults who become bed-bound face real risks from immobility, including pneumonia and blood clots, and that weighs into the decision.

Fractures caused by cancer weakening the bone are a separate category, where stabilization may be considered earlier as part of a broader treatment plan.

People are usually asked to wait, or offered something else, in several situations:

• The fracture is already healing well on repeat imaging and pain is trending down.
• There is an active infection anywhere in the body, since introducing a foreign material during infection raises the chance it becomes colonized.
• The back wall of the vertebra is broken or bone fragments already push toward the spinal canal, because cement could follow them.
• Bleeding is hard to control, for example because of anticoagulant medicines that cannot safely be paused.
• The pain does not match the fracture level, suggesting another cause.

The decision rests with the treating team after weighing imaging, examination, and how the person is actually coping day to day. A consent form lists what can go wrong; the conversation before it should explain why this person, at this moment.

Kyphoplasty complications: the full picture, not just the headline risk

Cement leakage gets the most attention, and rightly so, but it is one item on a longer list. Grouping kyphoplasty complications by mechanism helps make sense of them.

Problems related to the cement itself include leakage into the disc space above or below, leakage into veins with possible travel to the lungs, leakage backward into the spinal canal or the openings where nerve roots exit, and allergic or blood-pressure reactions during injection. Cement heats as it hardens, and heat near a nerve can irritate it.

Problems related to the needle and balloon include bleeding into the muscles of the back, fracture of the pedicle (the bony bridge the needle passes through), balloon rupture, and, rarely, direct injury to a nerve root or the spinal cord. Puncture of the lung lining is a recognized risk when the treated vertebra sits high in the chest.

Problems related to the person’s underlying condition include new fractures in neighboring vertebrae, fractured ribs from lying face down on brittle bones, and persistent pain despite a technically successful procedure.

Problems common to any procedure round out the list: infection at the skin or deep in the bone, reactions to sedation or anesthesia, and blood clots from reduced mobility.

Most of these are described as uncommon in patient information from academic centers, and serious neurologic injury is described as rare. The Cochrane review of vertebroplasty trials, which pooled placebo-controlled and open studies, reported that clinically important adverse events were infrequent across both real and sham procedures. Those are reassuring words, but they are also averages. What matters to an individual is knowing which symptom maps to which mechanism, so nothing important gets dismissed as ordinary soreness.

Cement leakage after kyphoplasty: where does the cement go, and does it matter?

A fractured vertebra is not a sealed box. Its outer wall is cracked, its top and bottom plates may be broken, and it is threaded with veins. Liquid cement pushed inside takes the path of least resistance, so some escaping is expected rather than exceptional.

Cement that leaks into the disc space, the cushion between vertebrae, is the most common pattern and usually causes no symptoms. Some researchers have asked whether cement in the disc stiffens the segment and stresses the next vertebra; the evidence is mixed and discussed later.

Cement that leaks into the soft tissue beside the spine, or forward into the space in front of it, is generally harmless and simply appears on later X-rays as a small white blob.

Cement that enters the vertebral veins can travel with the blood back toward the heart and lodge in the lungs. This is pulmonary cement embolism. Small fragments are often found incidentally on chest imaging and cause nothing. Larger amounts can cause chest pain, shortness of breath, cough, or a racing heart, sometimes within hours and occasionally days later. Case series in the medical literature describe this as uncommon and usually manageable, but it is the reason chest symptoms after spinal cement are never brushed aside.

Cement that leaks backward, into the spinal canal or the foramen where a nerve root exits, is the least common and the most consequential pattern. It can press on nerve tissue directly, and because hardening cement releases heat, it can also cause thermal irritation.

Two features make kyphoplasty leaks somewhat less likely than vertebroplasty leaks: the balloon cavity gives the cement a place to sit, and the thicker cement flows less freely. Neither eliminates the risk, and a competent operator watches the cement on live imaging and stops the moment it heads somewhere it should not.

Nerve pressure and radiculopathy: the leak that makes itself known

Radiculopathy means irritation or compression of a nerve root, the bundle of nerve fibers leaving the spinal cord at each level. In the mid and lower back, those roots run to the chest wall, abdomen, hips and legs, so a problem at one vertebra produces symptoms far from the injection site.

After cement augmentation, radiculopathy can arise in three ways. Cement may leak into the foramen and press the root directly. The needle may nick the root on its way in. Or a fragment of the broken back wall of the vertebra may be pushed backward, a retropulsed fragment, either during balloon inflation or in the weeks afterward as the bone settles. Published case reports describe delayed-onset radiculopathy weeks after an apparently uneventful kyphoplasty from exactly this mechanism, which is why new symptoms weeks later still count.

The feeling is distinct from the deep, central ache of the fracture. People describe a band of burning or electric pain wrapping around the ribs or abdomen, or shooting into the buttock and thigh. There may be a patch of numbness, tingling like pins and needles, or weakness such as a foot that slaps the floor.

Spinal cord compression, where cement or bone presses the cord itself rather than a single root, is rare but represents an emergency. Its signs are broader: weakness or numbness in both legs, unsteadiness, and difficulty controlling the bladder or bowel.

Treatment depends on cause and severity. Mild nerve irritation from a small leak is often managed with time and anti-inflammatory approaches under the team’s supervision. Significant compression may require surgery to remove the cement or fragment, sometimes through a minimally invasive endoscopic approach. None of this is decided by the patient at home; the job at home is to notice and report.

Adjacent-level fractures: does the cement cause the next break?

Perhaps the most debated of all kyphoplasty complications is the new fracture in the vertebra directly above or below the treated one. The theory is intuitive: a cement-filled vertebra is stiffer than its osteoporotic neighbors, so load that used to be shared now concentrates on the weaker bones next door.

The evidence is less tidy than the theory. People who have had one osteoporotic compression fracture are already at markedly increased risk of another whether or not they have cement placed, because the underlying bone disease has not changed. Osteoporosis resources from the National Institutes of Health and the NHS both emphasize that a first fragility fracture is one of the strongest predictors of a second. Disentangling how much of an adjacent fracture is due to cement stiffness and how much is simply the disease progressing has proven difficult, and studies point in different directions.

What most clinicians agree on:

• Adjacent fractures after augmentation do occur and tend to cluster in the first months.
• Cement leaking into the disc may increase the mechanical stress on the neighboring vertebra, which is one reason operators try to avoid it.
• Untreated osteoporosis is the larger, modifiable driver.

That last point deserves emphasis. A cement procedure fixes one bone; it does nothing for the other twenty-three. Bone-strengthening medicines, whether they slow bone breakdown or stimulate new bone formation, along with adequate calcium and vitamin D intake and fall prevention, address the reason the fracture happened in the first place. Decisions about which of these fits a given person belong to the prescribing clinician, but the question of whether bone health has been formally assessed is a fair one for any patient to raise before and after the procedure.

Symptoms of an adjacent fracture mimic the original: sudden new mid-back pain, often after minimal strain, at a level just above or below the treated one.

Infection, bleeding, and the risks that come with any procedure

Cement is a foreign material sitting inside bone for life. If bacteria reach it, they can form a stubborn film that antibiotics penetrate poorly. Deep infection of a cemented vertebra, a form of spondylitis or vertebral osteomyelitis, is rare, but it is serious enough that teams screen for active infection beforehand and use sterile technique and often a single dose of preventive antibiotic during the procedure.

Skin infection at the needle site is more common and less dangerous. Redness spreading beyond the puncture, warmth, discharge, or a fever in the first two weeks are the typical cues. Deep infection announces itself more slowly: pain that improves for a while and then worsens, night sweats, fatigue, or a low-grade fever weeks later. Blood tests and imaging sort this out; home guesswork does not.

Bleeding into the back muscles produces a tender, sometimes visible swelling and bruising. Because the needle passes near veins around the spine, people taking anticoagulants or antiplatelet medicines are usually asked to discuss timing with the prescriber beforehand. Nobody should stop these medicines on their own initiative; the balance between bleeding risk and clot risk is individual.

Face-down positioning on a hard table can fracture brittle ribs, producing sharp pain with breathing or coughing that is easily mistaken for a lung problem. Some people also notice temporary soreness or numbness where padding pressed on the chest or hips.

Sedation and anesthesia carry their own small risks, including nausea, breathing suppression, and confusion in older adults that usually clears within a day or two.

Transient drops in blood pressure during cement injection are recognized, thought to relate to the cement monomer or to fat and marrow being pushed into the circulation. Monitoring during the procedure is designed to catch this.

Finally, reduced mobility around any procedure raises the risk of a blood clot in the leg. Early walking, which is also the goal of the procedure, is the best countermeasure.

Kyphoplasty vs vertebroplasty risks: a side-by-side view

People often ask whether one procedure is safer. The honest answer is that they share almost the same list of possible problems, with differences of degree rather than kind. The table below summarizes what patient education from major academic centers and the trial literature generally describe.

Feature	Vertebroplasty	Kyphoplasty
Cement consistency	Thinner, injected under higher pressure	Thicker, placed into a balloon-made cavity
Cement leakage seen on imaging	More often reported	Less often reported
Symptomatic leaks	Uncommon	Uncommon
Height restoration attempt	No	Yes, via balloon
Balloon-specific risks	None	Balloon rupture, pedicle stress
Anesthesia	Usually local with sedation	Local with sedation or general
Procedure time	Shorter per level	Somewhat longer per level
Adjacent-level fracture	Reported	Reported
Infection, bleeding, nerve injury	Rare	Rare

A few caveats keep the table honest. Leakage rates vary enormously between studies depending on how hard the researchers looked; a CT scan finds far more tiny leaks than a plain X-ray, and most of what it finds is clinically silent. The Cochrane review of vertebroplasty, which examined the strongest trials, concluded with high-certainty evidence that the procedure offers no clinically important benefit over a sham procedure for pain and function in osteoporotic fractures, a finding that has made many teams more selective about who is offered either procedure.

Kyphoplasty has fewer placebo-controlled trials, so its benefit and risk profile is less firmly pinned down. Neither technique has been shown to be clearly superior for safety in a way that would override an individual team’s judgment about fracture shape, bone quality, and the operator’s own experience.

What are the symptoms of a failed kyphoplasty?

The phrase failed kyphoplasty covers two quite different situations, and it helps to separate them.

The first is a procedure that went technically as planned but did not relieve pain. This is more common than dramatic complications and, frustratingly, often has no single explanation. Possible reasons include pain that was never coming from the treated vertebra in the first place, an additional fracture that was missed or occurred afterward, arthritis in the small joints of the spine, muscle strain from months of guarding, or a fracture that had already begun healing so that stabilization added little. The Cochrane trial evidence, in which sham procedures relieved pain about as well as real vertebroplasty, is a reminder that the natural course of these fractures involves gradual improvement regardless.

Symptoms in this first group look like the original problem: a deep, central ache in the back that worsens with standing and eases lying down, present from the first days and not improving over the following weeks.

The second situation is a genuine complication. Symptoms here are new and different from the original pain:

• A band of burning, electric or shooting pain wrapping around the trunk or running down a leg.
• Numbness, tingling or weakness in a leg or foot.
• Sudden, sharp new pain at a slightly different level, suggesting an adjacent fracture.
• Pain that improved and then returned with fever, sweats or fatigue, suggesting infection.
• Chest pain, breathlessness or cough, suggesting cement in the lungs or a rib injury.

The distinction matters for what happens next. Persistent original-type pain usually leads to repeat imaging and a fresh look at other pain sources. New neurologic or systemic symptoms lead to urgent imaging, sometimes the same day. Either way, deciding which category a symptom belongs in is the team’s job, and the earlier they hear about it, the more options remain.

What the first days and weeks after kyphoplasty usually look like

Most people go home the same day or after one night, according to patient information from academic medical centers. The puncture sites are covered with small dressings. Soreness at those sites and in the back muscles is expected and typically fades over a few days.

Walking is encouraged early, often within hours, because mobility protects against clots, pneumonia and the muscle loss that immobility brings. Bending, twisting and lifting anything heavier than a few pounds are usually discouraged for a period the team specifies, commonly a couple of weeks, while the surrounding tissues settle.

Many people notice their fracture pain has changed within the first day or two. Some describe it as gone; others describe a different, more muscular soreness taking its place. Improvement that continues over the first two weeks is the pattern teams hope to see. Pain that plateaus early or drifts upward is worth mentioning at the follow-up visit rather than waiting.

A typical follow-up appointment happens within a few weeks and usually includes a plain X-ray to check cement position and vertebral height. This is also where an adjacent fracture would be caught if new pain has appeared.

On sleep, a question people ask constantly: there is no single correct position with a compression fracture, before or after cement. Lying on the back with a pillow under the knees, or on the side with a pillow between the knees, keeps the spine in a neutral line and is what physical therapists commonly suggest. Getting out of bed by rolling to the side and pushing up with the arms, rather than sitting straight up, reduces the twisting load on the mid-back. A firmer mattress tends to feel better than a soft one that lets the trunk sag. Whatever position allows sleep without sharp pain is acceptable; comfort is the guide, not a rule.

Physical therapy focused on posture, gentle extension and balance is commonly recommended once the acute phase passes, and it doubles as fall prevention.

Compression fracture healing time and the life expectancy question

Two searches sit right beside kyphoplasty complications in the questions people type: how long a compression fracture takes to heal, and what it means for life expectancy in older adults. Both deserve straight answers.

On healing time, MedlinePlus describes most compression fractures from injury as healing within roughly 8 to 10 weeks with rest, bracing and pain management, and other academic patient resources give a range of about two to three months. Bone heals on that timeline whether or not cement is placed; what cement changes, when it works, is how much the fracture hurts during that window, not the biology of bone repair. People with osteoporosis, diabetes, or who smoke may heal more slowly, and some vertebrae never regain their original height, leaving a permanent wedge. That wedge is why people lose height and develop a rounded upper back over years of repeated fractures.

On life expectancy, the research is sobering but needs context. Large population studies summarized by osteoporosis resources from the National Institutes of Health and major academic centers have found that older adults who suffer a vertebral fracture have higher mortality in the following years than peers who do not. The fracture itself is rarely the cause. Rather, it is a marker of frailty and often coincides with reduced mobility, which in turn raises the risk of pneumonia, blood clots, further falls and loss of independence. A vertebral fracture also signals that hip fracture risk is elevated, and hip fractures carry substantial mortality of their own.

The useful conclusion is not fatalism. A compression fracture is a warning that bone health and fall risk need serious attention: bone density testing, a conversation about bone-strengthening treatment, vision and footwear checks, balance training, and a home free of loose rugs. Those interventions address the mortality signal far more directly than any cement ever could.

What people often get wrong about kyphoplasty complications

Myth: any cement outside the bone is a disaster. Reality: small leaks into the disc or soft tissue are common findings on imaging and usually cause nothing. What matters is where the cement went and whether it produced symptoms, not whether the picture looks perfect.

Myth: if the pain is not gone by morning, the procedure failed. Reality: many people improve over days to two weeks, and muscle soreness from months of guarding can mask early gains. Persistent original-type pain at the follow-up visit is the point at which the team takes a fresh look.

Myth: the cement will wear out or need replacing. Reality: polymethylmethacrylate is a durable material used in joint replacements for decades. Long-term concerns center on the neighboring bones, not on the cement degrading.

Myth: cement prevents future fractures elsewhere. Reality: it stabilizes one vertebra only. The osteoporosis that broke it remains, which is why bone health treatment is the more important long-term conversation.

Myth: kyphoplasty restores full height and reverses the hunch. Reality: the balloon can recover some height in fresh fractures, but results vary widely, and older or already-healed fractures may not budge. Nobody should expect a straightened spine.

Myth: the procedure has been proven effective beyond doubt. Reality: the Cochrane review found high-certainty evidence that vertebroplasty does not outperform a sham procedure for osteoporotic fracture pain, and kyphoplasty has fewer rigorous trials. Reasonable clinicians disagree about when these procedures help, which is exactly why the decision is individualized rather than automatic.

Myth: complications only happen in the first day. Reality: adjacent fractures, delayed nerve compression from a shifting bone fragment, and deep infection can all surface weeks later. The window for reporting new symptoms stays open for months.

Questions to ask your care team before agreeing to kyphoplasty

A good pre-procedure conversation leaves a person able to explain, in their own words, why this procedure and why now. These questions tend to draw out the information that matters most.

• How do you know this specific vertebra is the source of my pain, and how recent is the fracture on imaging?
• What has conservative care achieved so far, and what would change if we waited another few weeks?
• Is the back wall of the vertebra intact? If not, how does that change the plan?
• Which procedure are you recommending, vertebroplasty or kyphoplasty, and what about my fracture makes that the better fit?
• What is your approach if cement starts to leak during the procedure?
• What kind of anesthesia will I have, and what are the risks given my other health conditions?
• Which of my regular medicines, particularly blood thinners, need to be discussed with the prescriber beforehand?
• What symptoms in the first two weeks would you want to hear about the same day, and how do I reach someone after hours?
• When is my follow-up, and will it include imaging?
• Has my bone density been measured, and who will manage treatment of the osteoporosis itself?
• What physical therapy or fall-prevention support is available afterward?
• If the pain does not improve, what would the next steps be?

Writing the answers down, or bringing someone to take notes, is worth doing. Consent conversations cover a lot in a short time, and the details about who to call and when tend to be the ones forgotten by the time they are needed.

None of these questions challenge the team’s expertise. They signal a patient who understands that the procedure is one part of a longer plan for a fragile spine, and most clinicians welcome exactly that.

When to call your doctor after kyphoplasty or vertebroplasty

Ordinary recovery includes puncture-site soreness, mild back muscle aching, bruising, and tiredness from sedation for a day or two. The signs below fall outside ordinary and warrant a call to the treating team, or emergency care where indicated.

Seek emergency care immediately for:

• New weakness in one or both legs, or difficulty walking that was not present before.
• Loss of bladder or bowel control, or new difficulty starting urination.
• Numbness in the groin or inner thighs.
• Chest pain, sudden shortness of breath, coughing up blood, or a racing heartbeat.
• Severe headache with neck stiffness, or confusion that does not clear.

Call the treating team the same day for:

• Burning, electric or shooting pain wrapping around the trunk or traveling down a leg, especially if it is new.
• Tingling or numbness in a leg or foot.
• Fever, chills, or night sweats.
• Redness spreading from the puncture site, warmth, swelling, or fluid leaking from it.
• Sudden new back pain at a different level, particularly after a minor strain.
• Sharp pain with breathing or coughing, which may indicate a rib injury.
• Calf pain, swelling or warmth in one leg, which may indicate a blood clot.

Mention at the next appointment, or sooner if worsening:

• Original fracture pain that has not improved at all after two weeks.
• Pain that improved and then gradually returned.
• Persistent nausea, poor appetite or unusual fatigue.

A short paragraph for the person at the kitchen table: the vast majority of people who have these procedures experience none of the emergency signs above. Knowing them is not about expecting the worst. It is about recognizing that a leg that will not lift or a bladder that will not empty is not something to sleep on, and that a phone call costs nothing while a delay can cost a great deal. Every decision about what those symptoms mean, and what to do about them, belongs to the treating team.

Frequently asked questions

What are the symptoms of a failed kyphoplasty?

A failed kyphoplasty most often means the original deep, central back pain simply did not improve, which may reflect pain coming from another source or a fracture that was already healing. True complications produce new and different symptoms: burning or electric pain wrapping around the trunk or down a leg, numbness, leg weakness, fever, or chest symptoms. Either pattern should be discussed with the treating team, who will decide whether repeat imaging is needed.

How common is cement leakage after kyphoplasty?

Cement leakage is a recognized and fairly frequent imaging finding after both kyphoplasty and vertebroplasty, with rates varying widely between studies depending on whether CT or plain X-ray was used to look. Most leaks are small, confined to the disc or soft tissue, and cause no symptoms. Kyphoplasty is generally reported to leak less often than vertebroplasty because thicker cement is placed into a balloon-made cavity at lower pressure.

Can cement from kyphoplasty travel to the lungs?

Yes. Cement that enters the veins around the vertebra can travel with blood flow to the lungs, a complication called pulmonary cement embolism. Small fragments are often found incidentally on chest imaging and cause no problems. Larger amounts can cause chest pain, shortness of breath, cough or a rapid heartbeat, sometimes hours to days after the procedure. Any chest symptoms after spinal cement placement warrant urgent medical assessment.

How long does it take to heal a compression fracture of the spine?

MedlinePlus describes most compression fractures as healing within roughly 8 to 10 weeks with rest, bracing and pain management, and other academic sources give a range of about two to three months. Cement procedures do not speed bone healing; when they help, they reduce pain during that window. Osteoporosis, diabetes and smoking can slow healing, and some vertebrae remain permanently wedge-shaped even after the bone knits.

What is the life expectancy after a compression fracture in elderly patients?

Population studies summarized by osteoporosis resources show that older adults who suffer a vertebral fracture have higher mortality in following years than peers who do not, but the fracture is a marker of frailty rather than the direct cause. Reduced mobility, further falls and hip fracture risk drive much of the difference. Bone-strengthening treatment, fall prevention and staying active address that risk far more directly than any single procedure.

What is the best way to sleep with a compression fracture?

There is no single correct position; comfort is the guide. Lying on the back with a pillow under the knees, or on the side with a pillow between the knees, keeps the spine neutral and is commonly suggested by physical therapists. A firmer mattress usually feels better than a soft one. Getting out of bed by rolling to the side and pushing up with the arms reduces twisting strain on the mid-back.

Does kyphoplasty cause fractures in the vertebrae next to it?

New fractures in the vertebra above or below a treated level do occur, and a stiff cemented bone may shift load onto weaker neighbors. However, anyone who has had one osteoporotic fracture is already at sharply increased risk of another regardless of treatment, and studies disagree on how much extra risk the cement adds. Treating the underlying osteoporosis is considered the most important way to reduce that risk.

Kyphoplasty vs vertebroplasty risks: which is safer?

The two procedures share almost the same list of possible complications, differing in degree rather than kind. Kyphoplasty is generally associated with fewer cement leaks because of its balloon cavity and thicker cement, but it adds balloon-specific risks and often takes longer. Neither has been proven clearly safer overall, and the choice depends on fracture shape, bone quality and the treating team’s judgment and experience.

How long after kyphoplasty can complications appear?

Some complications, such as cement leaks affecting a nerve or cement reaching the lungs, tend to appear within hours to days. Others surface later: adjacent-level fractures often occur within the first months, a retropulsed bone fragment can cause delayed nerve compression weeks afterward, and deep infection may build slowly over several weeks. New or changing symptoms remain worth reporting to the treating team for months after the procedure.

Does kyphoplasty actually work for compression fracture pain?

The evidence is genuinely mixed. The Cochrane review of vertebroplasty found high-certainty evidence of no clinically important benefit over a sham procedure for pain or function in osteoporotic fractures. Kyphoplasty has fewer placebo-controlled trials, so its benefit is less firmly established. Many teams therefore reserve these procedures for people with severe, persistent pain who have not improved with conservative care, and the decision is individualized.
