在成人脊柱畸形手术中，上器械椎体（UIV）骨折导致严重的并发症，如脊髓损伤，占0.5- 0.8%。尽管尖端-顶点距离对于防止股骨近端骨折手术中螺钉切出很重要，但这表明骨碎片的螺钉占用率也很重要。本研究的目的是探讨椎弓根螺钉（ORPS）占用率如何影响UIV骨折。术后1年UIV骨折的患者定义为骨折组（F）;其他患者定义为无骨折组（NF）。评价了ORPS、椎弓根螺钉（PS）切出、药物和骨密度。显著性差异（P
Upper instrumented vertebra (UIV) fracture in adult spinal deformity surgery leads serious complications, such as spinal cord injury in 0.5-0.8%. Although tip-apex distance is important for preventing screw cut-out in proximal femoral fracture surgery, this suggest that the screw occupancy rate for bone fragments is also important. The purpose of this study was to investigate how the occupancy rate of pedicle screws (ORPS) affects UIV fracture. Patients with UIV fracture 1 year after surgery were defined as the fracture group (F); others were defined as the no fracture group (NF). ORPS, cut-out of pedicle screw (PS), medications, and bone mineral density were evaluated. Significant differences (P
