Balloon kyphoplasty with calcium phosphate cement augmentation in treatment of osteoporotic vertebral compressive fractures / 中华骨科杂志

ABSTRACT

Objective To evaluate the efficacy and safety of balloon kyphoplasty in the treatment of painful osteoporotic vertebral compressive fractures. Methods From May 2000 to June 2002, 56 consecutive procedures were performed in 30 patients of painful osteoporotic vertebral compressive fractures with intact posterior vertebral body wall. Each procedure includes bilateral insertion of inflatable balloon, fracture reduction and fulfilled with bone cement. Preoperative and postoperative symptom levels, complications and radiographic findings were recorded and analyzed. Results All 30 patients tolerated the procedure well with immediate relief of their back pain in 48 hours. The mean loss of the anterior and mid vertebral body heights were (13.6?2.3) mm, (9.2?1.4) mm preoperatively and (4.7?1.5) mm, (3.4?1.1) mm postoperatively. The mean kyphosis was improved from 23.4??5.2? to 9.2??4.7?. Cement leakage and cerebrospinal fluid leakage occurred at one level respectively and resulted in no clinical symptoms, no other complication was found. Conclusion As a promising minimally invasive surgery, balloon kyphoplasty can provide early improvement of pain and function as well as spinal alignment in treatment of painful osteoporotic compressive fractures.
