Percutaneous kyphoplasty in treating thoracolumbar osteoporosis vertebral burst fractures / 中国医师进修杂志

ABSTRACT

Objective To evaluate the feasibility of percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral burst fractures (OVBF) without nerve injury, and observe the clinical therapeutic effect. Methods A total of 32 patients with primary OVBF without nerve injury were treated by PKP from January 2009 to January 2013. The volume of bone cement intraoperative injection and complications after operation were observed. The visual analog scale (VAS) and Oswesty disability index (ODI) before and after operation were metered to evaluate pain relief and improvement of life quality. The Beck index, Cobb angle and vertebral canal bones occupying rate were metered before and after operation to evaluate the recovery of vertebral body height, correction of kyphosis and change of intraspinal bone block position. Results There were no serious complication occurred. The operation time was (52.05± 7.60) min, the volume of bone cement intraoperative injection was (4.08 ± 1.50) ml. After operation for one day, the VAS decreased from (7.89±0.52) scores to (2.31±0.39) scores, the Cobb angle decreased from (19.15±3.20)°to (11.19±2.58)°, the Beck index increased from 0.46±0.06 to 0.61±0.07, there were significant differences (P<0.01 or<0.05). The rate of spinal bones occupying after operation for one day was not decreased obviously, but after operation for 3 months, it decreased from (17.89±5.03)%to (9.18±4.17)%, there was significant difference (P<0.05).The ODI before operation was (76.89± 6.72) scores, after operation for 3 months was (30.86± 7.25) scores, there was significant difference (P<0.01). Conclusions The pain could be relieved effectively, and the quality of life could be improved by the method of PKP in treating OVBF. Meanwhile, the vertebral body height and kyphosis could be corrected and the rate of spinal bones occupying could not be increased significantly.
