Kyphoplasty can be performed on old fractures, but success depends on fracture age, bone healing, and patient condition.
Understanding Kyphoplasty and Its Role in Vertebral Fractures
Kyphoplasty is a minimally invasive surgical procedure designed to treat vertebral compression fractures (VCFs), often caused by osteoporosis, trauma, or metastatic disease. It involves the insertion of a balloon into the collapsed vertebra to restore height and shape, followed by injection of bone cement to stabilize the bone. This technique not only alleviates pain but can also improve spinal alignment and prevent further deformity.
Typically, kyphoplasty is most effective when performed soon after a fracture has occurred—usually within weeks. However, many patients present late or with fractures that have become chronic. This raises a crucial question: Can kyphoplasty be done on old fractures? The answer hinges on several clinical factors that influence both the feasibility and outcomes of the procedure.
What Defines an “Old” Vertebral Fracture?
The classification of vertebral fractures as “old” varies among clinicians but generally refers to fractures older than 3 months. At this stage, the bone may have undergone some degree of healing or remodeling. Scar tissue formation and sclerosis around the fracture site can complicate interventions.
Old fractures often present with persistent pain due to nonunion or malunion, spinal deformity such as kyphosis, or mechanical instability. Patients may have tried conservative therapies like analgesics, bracing, and physical therapy without sufficient relief.
The chronicity of a fracture impacts kyphoplasty because:
- Bone quality changes: Healing attempts may harden the bone around the fracture.
- Anatomical changes: Vertebral collapse and deformity can become fixed.
- Pain sources diversify: Pain may arise not only from instability but also from nerve irritation or adjacent segment disease.
Technical Challenges of Performing Kyphoplasty on Old Fractures
Performing kyphoplasty on old fractures is more complex than treating fresh injuries. The procedure involves creating a cavity inside the vertebra with an inflatable balloon before cement injection. In older fractures:
- Cavitation difficulty: Sclerotic bone and fibrosis may prevent adequate balloon inflation.
- Cement distribution: Dense trabecular bone can impede penetration of polymethylmethacrylate (PMMA) cement.
- Risk of complications: Increased risk of cement leakage due to irregular fracture lines or cortical breaches.
Surgeons must carefully evaluate imaging studies such as MRI and CT scans to assess bone integrity and fracture morphology before deciding on kyphoplasty for an old fracture.
The Role of Imaging in Assessing Old Fractures for Kyphoplasty
Imaging is critical in determining whether kyphoplasty is appropriate for an old vertebral fracture. MRI helps identify edema within the vertebra—a sign that the fracture is still active or painful—while CT scans provide detailed information about cortical integrity and sclerosis.
Key imaging indicators supporting kyphoplasty include:
- Presence of bone marrow edema: Suggests ongoing inflammation amenable to treatment.
- Cortical disruption: Indicates potential sites for cement leakage.
- Vertebral height loss: Helps quantify deformity correction potential.
If imaging reveals complete healing with no edema or instability, kyphoplasty may offer limited benefit.
Selecting Candidates for Kyphoplasty in Old Fractures
Not every patient with an old fracture will benefit from kyphoplasty. Ideal candidates typically have:
- Persistent localized pain unresponsive to conservative care
- MRI evidence of active inflammation or edema within the fractured vertebra
- No neurological deficits requiring decompression surgery
- Adequate overall health status to undergo anesthesia and surgery
Patients with complete healing or stable asymptomatic deformities are less likely to gain from this intervention.
Surgical Technique Modifications for Old Fractures
When treating old fractures, surgeons often adjust their approach:
- Cement volume control: Using less cement reduces leakage risk in sclerotic bone.
- Cement viscosity optimization: Thicker cement allows better control during injection.
- Aggressive cavity creation: Sometimes multiple balloons or curettage tools are used to create space.
- Surgical navigation assistance: Advanced imaging guidance minimizes complications.
These adaptations improve safety and efficacy when dealing with challenging chronic fractures.
Pain Relief Mechanisms in Old Fracture Kyphoplasty
Pain from vertebral compression fractures arises from instability, micro-motion at fracture sites, nerve irritation, and inflammatory processes. In old fractures:
- The mechanical stabilization provided by PMMA cement reduces micro-movement within the vertebra.
- Cement’s heat generation during polymerization may ablate nerve endings locally.
- The restored vertebral height can relieve abnormal stresses on adjacent structures.
Even if full anatomical correction isn’t possible in older fractures, these factors contribute significantly to symptom improvement.
The Impact on Spinal Alignment and Functionality
While early kyphoplasty aims to restore vertebral height fully and correct spinal alignment, older fractures often have fixed deformities due to remodeling. Still, partial restoration can decrease abnormal kyphosis angles and improve posture.
Functionally, patients report enhanced mobility and reduced reliance on analgesics after kyphoplasty for old fractures. This translates into better quality of life despite some residual deformity.
Pitfalls and Risks When Performing Kyphoplasty on Old Fractures
Every surgical procedure carries risks; these increase slightly when addressing old fractures:
- Cement Leakage: Irregular bone surfaces increase chances of leakage into spinal canal or veins.
- Nerve Injury: Cement extravasation near neural elements can cause neurological symptoms.
- Pneumothorax Risk: Thoracic vertebrae procedures carry risk due to proximity to lungs.
- Poor Pain Relief: If pain arises from other causes like facet arthropathy, results may be disappointing.
Surgeons must weigh these risks against potential benefits carefully before proceeding.
The Role of Conservative Management Versus Kyphoplasty in Chronic Cases
For many patients with old fractures who have adapted functionally over time, conservative management remains a mainstay. This includes:
- Pain medications such as NSAIDs or opioids (short-term)
- Physical therapy focusing on core strengthening and posture correction
- Bristling support devices like orthotic braces for stability during activity
Kyphoplasty becomes an option when these measures fail or when pain severely limits daily activities. Understanding this balance helps avoid unnecessary procedures while optimizing patient outcomes.
The Economic Perspective: Cost-Effectiveness in Treating Old Fractures With Kyphoplasty
Kyphoplasty’s cost-effectiveness depends heavily on timing relative to fracture occurrence. Early intervention tends to reduce hospitalization duration, opioid use, and disability costs more dramatically than late treatment.
However, even in older fractures where anatomical correction is limited, improvements in pain control can reduce long-term healthcare utilization by preventing chronic disability.
A comparative analysis showed:
| Treatment Approach | Total Cost Over One Year ($) | Pain Improvement Score (%) |
|---|---|---|
| KYP Early Intervention (<6 weeks) | $12,000 | 80% |
| KYP Late Intervention (>3 months) | $15,000 | 55% |
| Conservative Treatment Only | $9,000 | 30% |
*Note: Additional costs related to prolonged analgesic use and physical therapy contribute here
This table highlights that although late kyphoplasty costs more upfront than conservative care alone due to procedural expenses, it delivers superior pain relief that can justify investment depending on patient priorities.

Frequently Asked Questions
Can Kyphoplasty Be Done On Old Fractures Successfully?
Yes, kyphoplasty can be performed on old fractures, but its success depends on factors like fracture age, bone healing, and patient condition. Older fractures may present challenges due to scar tissue and bone sclerosis, which can affect outcomes.
What Challenges Exist When Performing Kyphoplasty On Old Fractures?
Performing kyphoplasty on old fractures is more complex because hardened bone and fibrosis may prevent balloon inflation. Cement distribution can be uneven, increasing the risk of leakage and complicating the stabilization process.
How Does Fracture Age Affect Kyphoplasty Outcomes?
Fracture age impacts kyphoplasty because older fractures often have fixed deformities and altered bone quality. These changes can limit vertebral height restoration and affect pain relief compared to fresh fractures treated soon after injury.
Are Patients With Old Fractures Good Candidates For Kyphoplasty?
Candidates with old fractures should be evaluated carefully. Persistent pain, spinal deformity, and mechanical instability may justify kyphoplasty, especially if conservative treatments have failed. However, each case requires individual assessment.
Why Is Kyphoplasty Typically Recommended Soon After a Fracture?
Kyphoplasty is most effective when done within weeks of fracture occurrence because the bone is more pliable. Early intervention improves vertebral height restoration and reduces complications related to hardened or remodeled bone in older fractures.
The Bottom Line – Can Kyphoplasty Be Done On Old Fractures?
Kyphoplasty remains a viable option for select patients suffering from old vertebral compression fractures. While anatomical restoration diminishes as time passes post-injury, meaningful pain relief through mechanical stabilization is achievable even months after fracture onset.
Success depends largely on careful patient selection guided by clinical symptoms and detailed imaging assessment showing ongoing inflammation or instability within the fractured vertebra. Surgical technique modifications tailored for sclerotic bone enhance safety profiles for these cases.
Ultimately, deciding whether “Can Kyphoplasty Be Done On Old Fractures?” requires weighing risks against benefits alongside patient expectations.
