ObjectiveTo explore the clinical outcomes of percutaneous vertebroplasty(PVP), percutaneous kyphoplasty(PKP) and percutaneous hollow pedicle screw with lateral holes implanted bone cement reinforcement in treating osteoporotic vertebral compression fracture(OVCF).MethodsFrom May 2012 to November 2013, the clinical data of 90 patients with osteoporotic vertebral compression fracture were retrospectively analyzed. According to the different methods of operation, the patients were divided into three groups, including the percutaneous hollow pedicle screw with lateral holes implanted bone cement reinforcement group (group A), percutaneous vertebroplasty group (group B), percutaneous kyphoplasty group (group C), each group had 30 patients. Pre operative, postoperative at 1 day, 3 months, 1 year, the back pain was assessed by visual analogue scale(VAS), and vertebral height compression ratio, Cobb angle were measured by X-rays.ResultsAll operations were successful and no complications such as postoperative infections and deep vein thrombosis were found. At the final follow up, there were 2 patients with mild postoperative back pain in group A;7 patients with moderate postoperative back pain, 4 patients with severe postoperative back pain, 2 patients with postoperative vertebral refracture in group B; 5 patients with moderate postoperative back pain, 3 patients with severe postoperative back pain, 4 patients with postoperative vertebral refracture in group C. Postoperative VAS, vertebral height compression ratio, Cobb angle of all patients have obviously improved than preoperative(P<0.05). On 1 day, 3 months, 1 year after operation, there was significant difference between group A and group B, C(P<0.05), there was no significant difference between group B and group C(P>0.05). There was no significant difference in group A above items and different times(P>0.05), and there was significant difference in group B, C above items and different times(P<0.05).ConclusionsThe effect of PVP and PKP on the immediately postoperative pain relief was more than percutaneous hollow pedicle screw with lateral holes implanted bone cement reinforcement in treating osteoporotic vertebral compression fracture, but, residual back pain can happen in different extent in the patients underwent PVP and PKP. Percutaneous hollow pedicle screw with lateral holes implanted bone cement reinforcement technique has obvious advantage in recovery of the vertebral height, correction of vertebral deformity, reduction of postoperative back pain.
