[Effectiveness comparison between unilateral and bilateral percutaneous kyphoplasty for Kümmell disease].

Objective: To compare the effectiveness between unilateral and bilateral percutaneous kyphoplasty (PKP) in the treatment of Kümmell disease. Methods: >0.05). The operation time, intraoperative fluoroscopy times, amount of injected bone cement, and hospitalization time were recorded, and the situation of bone cement leakage was observed. The VAS score, ODI, anterior vertebral height, and kyphosis Cobb angle were evaluated before operation, at 1 day after operation, and at last follow-up. Results: >0.05). Conclusion: Both unilateral and bilateral PKP can achieve good effectiveness in treatment of Kümmell disease. But the unilateral puncture technique possesses advantages such as shorter operation time, less radiation dose, and less amount of injected bone cement.
