What kyphoplasty is
Balloon kyphoplasty is a minimally invasive procedure for painful vertebral compression fractures, most of which occur in osteoporotic bone [V1][V2]. Through a small puncture, a needle is guided into the fractured vertebra under imaging, a balloon inflates to create a cavity and partially restore height, and bone cement fills the space to stabilize the fracture [V1]. It treats mechanical fracture pain — not arthritis, disc pain, or nerve compression.
Key numbers
- Same day: usual discharge timing for an uncomplicated case [V1].
- 24–72 hours: typical onset of meaningful pain relief [V1].
- 80–90%: pain improvement reported in well-selected series [V1].
- Weeks to a few months: the fracture age range in which the procedure works best [V1].
- Most cement leaks: asymptomatic and found only on imaging [V1].
Step 1: Conservative care first
Most compression fractures are managed initially without a procedure: analgesia, short-term activity modification, bracing in selected cases, early mobilization, and treatment of the underlying osteoporosis [V2]. Many fractures settle over 4 to 8 weeks. Kyphoplasty is considered when pain remains severe and functionally limiting, and imaging confirms an acute or non-healed fracture that matches the painful level.
Step 2: Confirming you are a candidate
- Focal pain over the fracture level, worse with standing, walking, and position change.
- MRI showing edema — evidence that the fracture is still active rather than healed [V1].
- No better explanation for the pain, such as facet arthropathy or radiculopathy.
- Fitness for prone positioning and sedation.
Step 3: The procedure
You lie face down, usually under sedation with local anesthetic, sometimes general anesthesia. Under fluoroscopy the needle is advanced into the vertebral body, the balloon is inflated, then cement is injected and allowed to harden over several minutes. Total time is typically 30 to 60 minutes per level. You are observed for a couple of hours, walk, and go home the same day [V1].
Step 4: Recovery and aftercare
Expect puncture-site soreness for a few days. Walking begins immediately; heavy lifting, bending, and twisting are limited for a few weeks. Posture and back-extensor strengthening usually start within one to two weeks — important because strength protects adjacent levels. Critically, the underlying bone disease must be treated: calcium and vitamin D adequacy, fall prevention, and prescription osteoporosis therapy where indicated [S1][S2].
Kyphoplasty versus vertebroplasty
| Feature | Kyphoplasty | Vertebroplasty |
|---|---|---|
| Cavity created first | Yes, with a balloon | No |
| Cement injection pressure | Lower | Higher |
| Height restoration | Partial, sometimes | Minimal |
| Cement leakage rate | Lower | Higher |
| Pain relief | Broadly similar | Broadly similar |
Risks
Cement leakage is the most common finding and usually causes no symptoms; rarely it can compress a nerve or embolize [V1]. Other risks include infection, bleeding, rib or pedicle fracture during access, and anesthesia-related events. Adjacent-level fractures can occur afterwards, which reflects untreated osteoporosis more than the procedure itself [V1][V2].
Red flags requiring urgent care
New leg weakness, numbness around the groin, or bladder or bowel changes after a compression fracture suggests canal compromise and needs emergency imaging [V2]. Fever, escalating pain, or wound discharge after the procedure needs same-day review.

Frequently asked questions
What is the recovery time after kyphoplasty?
Most people go home the same day and walk within a few hours. Pain relief often begins within 24 to 72 hours. Light activity resumes immediately, with heavy lifting and twisting avoided for a few weeks. Physical therapy for posture and back strength usually starts within one to two weeks.
What is the success rate of kyphoplasty?
In well-selected patients with an acute, painful fracture confirmed on imaging, published series report substantial pain improvement in roughly 80% to 90%. Results are considerably worse when the fracture is old and healed, or when pain is coming from another source such as the facet joints or a nerve root.
Is kyphoplasty safe for elderly patients?
It is commonly performed in people in their seventies and eighties and is usually done under sedation or light anesthesia through a small skin puncture. The main considerations are cardiopulmonary fitness for positioning face down and the risk of cement leakage. For many older adults, the alternative of prolonged immobility carries greater risk.
What is the difference between vertebroplasty and kyphoplasty?
Vertebroplasty injects cement directly into the fractured vertebra. Kyphoplasty first inflates a balloon to create a cavity and partially restore height, then fills it with cement at lower pressure. Kyphoplasty may restore a little more height and has lower cement-leakage rates; pain relief is broadly similar.
Can kyphoplasty be done on old fractures?
Sometimes, but results are less predictable. The procedure works best on fractures that are still acute or non-healed, typically within a few weeks to a few months and showing edema on MRI. A fully healed fracture is unlikely to be the pain source, so treating it rarely helps.
