[Clinical study of percutaneous vertebroplasty through extreme extrapedicular approach in the treatment of osteoporotic vertebral compression fracture].

OBJECTIVE: To evaluate the effectiveness of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic vertebral compression fracture (OVCF) through unilateral puncture of extreme extrapedicular approach and bilateral injection of bone cement. METHODS: >0.05). The radiation exposure time, operation time, volume of bone cement injection, rate of bone cement leakage, pre- and post-operative visual analogue scale (VAS) score and local Cobb angle were recorded and compared between the two groups. RESULTS: <0.05). CONCLUSION: It is simple, safe, and feasible to use the unilateral puncture of extreme extrapedicular approach and bilateral injection of bone cement to treat OVCF. Compared with the transpedicular approach, the bone cement can be distributed bilaterally in the vertebral body without prolonging the operation time and radiation exposure time, and has an advantage of decreasing long-term local Cobb angle losing of the fractured vertebrae.
