Kyphoplasty for Vertebral Compression Fractures

Recommendations for Kyphoplasty

The American Heart Association recommends kyphoplasty as a reasonable therapeutic option for patients with severe back pain from vertebral compression fractures that is refractory to conservative medical therapy, with stronger evidence supporting its use in cancer-related fractures than in osteoporotic fractures (AHA Class IIA, Level of Evidence B) 1
Kyphoplasty is superior to conservative medical therapy in reducing back pain, disability, and improving performance status and quality of life for patients with cancer and disabling back pain from vertebral fractures (AHA Class IIA, Level of Evidence B) 1

Kyphoplasty provides significant pain reduction, with earlier achievement of significant pain relief compared to conservative treatment (30 days vs 116 days) 2
Kyphoplasty improves functional outcomes, with significant improvement in quality of life scores, and improved performance status scores, with 75% of kyphoplasty patients improving to a score of at least 70 (threshold for self-care) compared to 39% in conservative treatment 3

Cement leakage is a common complication of kyphoplasty, though often asymptomatic, and can lead to rare but serious complications such as pulmonary embolism from cement leakage into the venous system 1
Procedural risks of kyphoplasty include infection 1 and bleeding (particularly important in anticoagulated patients) 4

Conservative management, including analgesics, bed rest, back braces, physical therapy, and rehabilitation, as well as medical therapy for osteoporosis, is an alternative to kyphoplasty 3
Vertebroplasty is a similar procedure to kyphoplasty, without balloon inflation, and may provide better pain relief according to some meta-analyses, with a similar complication profile 5 and is less expensive than kyphoplasty (approximately 2.5 times less costly) 6

Patient selection is critical, and kyphoplasty shows better outcomes in the first month, but long-term outcomes may be similar to conservative treatment in properly selected patients, with earlier intervention warranted for cancer-related fractures 1
Post-procedure care includes bed rest, observation, regular assessment of vital signs and neurological function, supervised ambulation, and most patients can be discharged the same day or after overnight observation 1
Follow-up is necessary to assess pain levels, mobility, and analgesic requirements, and patients should be counseled to report any sudden increase or new back pain as it may indicate a new fracture, with prevention of future fractures particularly important 1

Kyphoplasty costs approximately 2.5 times more than vertebroplasty due to additional equipment, anesthesia, and hospital costs, according to the Journal of Neurointerventional Surgery 7

No head-to-head studies have compared kyphoplasty with vertebroplasty, making definitive superiority claims impossible, as noted in the Journal of Neurointerventional Surgery 7

Patients with vertebral compression fractures older than 12 weeks experience pain relief comparable to those with fractures younger than 12 weeks, indicating fracture age does not independently affect analgesic outcomes. 8
In the VERTOS II trial, significant pain relief from conservative medical management was typically achieved by three months post‑fracture. 8
Approximately 40 % of patients managed conservatively fail to achieve meaningful pain reduction after one year, and roughly 20 % progress to chronic back pain despite advanced analgesic therapy. 8

Bone‑marrow edema identified on MRI generally resolves within one to three months after fracture onset. 8
Most osteoporotic vertebral compression fractures demonstrate gradual pain improvement over a period of two to twelve weeks under conservative care. 8

Kyphoplasty is indicated when spinal deformity meets any of the following thresholds: kyphosis ≥ 15 %, scoliosis ≥ 10 %, dorsal wall height reduction ≥ 10 %, or vertebral body height loss ≥ 20 %. 8
Development of pulmonary dysfunction secondary to kyphotic deformity constitutes a justification for kyphoplasty. 8
The procedure is recommended to mitigate secondary complications of prolonged immobility, including reduced bone mineral density, increased risk of deep venous thrombosis, and cardiovascular or respiratory deconditioning. 8
Evidence demonstrates that fracture chronicity alone does not preclude clinical benefit from kyphoplasty, supporting its use even in chronic fractures when symptoms persist. 8

Standard conservative treatment yields gradual pain relief over 2–12 weeks, with MRI‑detected bone‑marrow edema typically resolving within 1–3 months. 8
Despite this, a substantial proportion of patients (≈40 %) remain with significant pain after one year, and about one‑fifth develop chronic back pain, underscoring the need for timely intervention when conservative measures fail. 8
