Adult spinal deformity (ASD) surgery aims to correct abnormal spinal alignment in both the sagittal and coronal planes to alleviate pain and improve functional activities of daily living. Despite the advancements in surgical techniques that have led to better clinical outcomes, postoperative mechanical complications remain. These complications include instrumentation failure, with proximal junctional kyphosis (PJK), proximal junctional failure (PJF), and rod fractures (RFs) being the most common. Such complications deteriorate clinical outcomes and often require revision surgery, which can be more burdensome for surgeons and patients, than index surgery. Thus, the risk factors for mechanical complications must be identified, and effective preventive strategies established. Therefore, this study aimed to review the risk factors for mechanical complications, focusing on PJK, PJF, and RF, and explore prevention strategies for these complications in ASD surgery, drawing upon recent literature.
成人脊柱畸形（ASD）手术旨在矫正矢状面和冠状面的脊柱异常排列，以减轻疼痛并改善日常生活功能活动。尽管手术技术的进步带来了更好的临床结果，但术后机械并发症仍然存在。这些并发症包括内固定失败，其中近端交界性后凸（PJK）、近端交界性失败（PJF）和棒材骨折（RFs）最为常见。此类并发症会恶化临床结果，且通常需要翻修手术，这对比初次手术而言，对外科医生和患者来说负担可能更大。因此，必须确定机械并发症的危险因素，并制定有效的预防策略。所以，本研究旨在回顾机械并发症的危险因素，重点关注PJK、PJF和RF，并借鉴近期文献探讨ASD手术中这些并发症的预防策略。
