Percutaneous kyphoplasty in treating osteoporotic vertebral compression fracture with kyphotic deformity: a compared study

Abstract

Abstract Background To evaluate the efficacy and safety of percutaneous kyphoplasty (PKP) for thoracolumbar osteoporotic vertebral compression fracture (OVCF) with kyphosis via unilateral versus bilateral approach. Methods All patients suffered OVCF with kyphosis were retrospectively reviewed. Of those, performed unilateral PKP or underwent bilateral PKP with random. The clinical and radiological data such as the correction of deformity, sagittal profle and record of the perioperative morbidity of the patients were analyzed. Results All patients (76 ± 3.6 years) were enrolled in this investigation, including 41 in the unilateral and 45 in the bilateral group. No significant difference in general data was detected between the two groups (p > 0.05). Howere, the operation time and cement amount 28.2 ± 3.4 min, 3.8 ± 0.6 ml in the unilateral group, while 50.1 ± 4.6 min, 5.4 ± 0.5 ml in the bilateral group, respectively (P < 0.05).In addition,The preoperative visual analog scale(VAS) and Vertebral local kyphosis angle were 8.8 ± 0.65 and 16.3 ± 6.5°compared to last follow-up 3.15 ± 0.78 and 14.26 ± 2.16°in unilateral group, while 8.5 ± 0.78 and 16.5 ± 7.1°compared to last follow-up 2.66 ± 0.86 and 13.81 ± 2.38°in bilateral group, respectively (P < 0.05). Furthermore, Oswestry Disablility Index (ODI) and prevertebral height ratio in both groups were significantly different before and after surgery, but no significant difference between the two groups (p > 0.05). Conclusions Both bilateral and unilateral PKP are relatively safe and provide effective treatment for patients with painful thoracolumbar osteoporotic vertebral compression fracture with mild kyphotic deformity. However, unilateral PKP need less operation time and volume of cement.
