Abstract:

BACKGROUND: The percutaneous kyphoplasty may form a cavity with surrounding relatively tight cancellous bone in vertebral body through balloon compression expansion, can effectively reduce the leakage rate of bone cement, at the same time the expanding balloon contributes to reduce collapsed vertebral body and correct kyphosis.
OBJECTIVE: To retrospectively analyze the influence of manual reduction combined with percutaneous kyphoplasty bone cement on fracture leakage and vertebral height restoration in treatment of osteoporotic vertebral compression fracture.
METHODS: Thirty-one patients (41 vertebras) with osteoporotic vertebral compression fracture, aged 53-82 years at a mean of 69 years, were treated with manual reduction and percutaneous kyphoplasty from February 2008 to June 2010 in Department of Orthopedics, General Hospital of Huabei Oil Field Company. Prior to operation, the lumbar part was over-extending reduction by manipulation. The postoperative pain relief, vertebral height restoration and bone cement leakage were recorded during follow-up.
RESULTS AND CONCLUSION: All the patients were involved in follow-up for 8-13 months, with an average (11±1.6) months. The visual analogue scale was reduced from (6.7±1.9) points preoperation to (1.3±1.2) points postoperation, with significant differences (P < 0.05). The vertebral height was restored from (15.7±5.2) mm preoperation to (20.2±4.5) mm postoperation, with significant differences (P < 0.05). Extra vertebral leakage of bone cement was observed in three vertebrae with no marked clinical symptoms. Manual reduction combined with percutaneous kyphoplasty is a safety method for osteoporotic vertebral compression fracture, for advantages of pain relief, significant restoration of the vertebrae height and minor the leakage of bone cement.
