概括

对近距离连接失效 (PJF) 的修订策略取决于近距离连接角度 (PJA) 校正. 将融合延长至少8个层次,可以最大限度地减少近端结节 (PJK) 和PJF的复发.

科学领域:

脊柱外科手术脊柱外科手术
整形外科的研究研究.
外科手术的结果

背景情况:

靠近结节衰竭 (PJF) 是脊髓融合后的一种并发症.
对于PJF的最佳修订策略,包括角度校正和融合扩展,需要进一步定义.

研究的目的:

在PJF的修复手术期间确定焦点角度校正和近端延伸的最佳策略.
调查近距离结角 (PJA) 减小和近距离结角 (PJK) 和/或PJF复发之间的相关性.

主要方法:

一个前性收集的多中心数据库的回顾性审查.
对134名接受PJF检查的患者进行分析.
按PJK校正度和近接延伸水平进行分层,以报告放射性PJK和经常性PJF率.

主要成果:

在PJA减少和复发PJK (r = -222) 之间观察到相关性.
复发的PJK和PJF很少见 (0%和4.5%) 在融合扩展≥8水平的患者中.
患有大PJA减少 (>30°) 和<8级延伸的患者的复发率最高 (31.8%PJK,16.0%PJF).

结论:

通过将PJA减小到<30°,可以将PJK的复发减少到最低.
更广泛的近接融合结构 (≥8级) 可以减轻复发的PJK/PJF速率,特别是当需要更大的PJA校正时.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
