Modified Percutaneous Vertebroplasty with Bilateral Cannulated Screws and Staged Cement Injection for Stage I and II Kummell’s Disease: A Mid-to-Long Term Follow-Up Study
This mid-to-long term follow-up study demonstrates that a modified percutaneous vertebroplasty technique utilizing bilateral cannulated screws, steerable cement delivery, and staged injection is a safe and feasible treatment for Stage I and II Kummell's disease, providing sustained pain relief, functional improvement, and durable vertebral height restoration while minimizing complications like cement loosening and re-collapse.
