The clinical efficacy of unilateral percutaneous kyphoplasty for the treatment of elder patients with osteoporotic vertebral compression fractures

Abstract

Objective To retrospectively investigate the clinical efficacy of unilateral percutaneous kyphoplasty (PKP) for the treatment of elder patients with osteoporotic vertebral compression fractures(OVCF). Methods One hundred and twelve elder patients, aged≥60 years old, both sexes, with osteoporotic vertebral compression fractures were treated by PKP from February 2011 to February 2019 in the department of Orthopedics of Yucheng People's Hospital. The visual analogue scale (VAS), height of vertebral body and Cobb angle were evaluated before and after the operation. Results All patients were successfully operated. The vertebral height was significantly improved from (18.42±2.31) mm before PKP to (27.67±2.53) mm and (27.13±2.75) at the 3 days and 3 months after the operation (all P<0.05). The local Cobb angle was significantly reduced from (25.83±7.14)° before PKP to (13.79±7.25)° and (13.17±7.43)° at the 3 days and 3 months after the operation (all P<0.05). The average VAS significantly decreased from (7.56±1.25) before PKP to (3.05±1.34), (3.05±1.34), (2.96±1.27) and (2.91±1.19) at the 3 days,1 month, 3 months and 6 months, respectively (all P<0.05). VAS 0-3 was in 97, 101, 100 and 99 patients at the 3 days, 1 month, 3 months and 6 months after the operation respectively. Conclusion Unilateral percutaneous kyphoplasty can efficiently relieve back pain, restore the vertebral height and correct the kyphosis in the treatment of elder patients with osteoporotic vertebral compression fractures.
