Abstract: 【Abstract】 Objective To observe and compare the efficacy of unipedicular and bipedicular percutaneous kyphoplasty for treating osteoporotic vertebral compressive fractures. Methods A total 32 patients with osteoporotic vertebral compression fractures in single segment vertebral body were included in the study. Of them,16 cases underwent unipedicular percutaneous kyphoplasty (unipedicular group) and another 16 were received bipedicular percutaneous kyphoplasty bipedicular group)..The complication, Kyphosis Cobb's angle, pain relief index score (VAS score), ADL score and operation duration were compare between two groups. Results There was no significant difference in occurrence of complication, pain relief and correction of spinal Kyphosis Cobb's angle in 6 month after operation between two groups. The operation duration of unipedicular kyphoplasty group was short than that of bipedicular kyphoplasty group (P>0.05). After operation in 6 months, Cobb's angle in unipedicular group was 4.8°±0.5° and less than that in bipedicular group (t=-14.840, P<0.001). VAS score in unipedicular group was 2.2±0.3 and less than that in bipedicular group (2.4±0.3)(t=-1.886, P=0.069). Kyphosis Cobb’s angle, pain relief index score (VAS score), ADL score in two groups were getting better than that before operation. Conclusion〓The effect of pain relief, Kyphosis Cobb's angle correctic and occurrence of complication between unipedicular with bipedicular kyphoplasty are similar, but the unipedicular kyphoplasty has the advantage of less operation time and simpler procedure.
