后路脊柱融合术治疗青少年特发性脊柱侧凸的畸形相关并发症

青少年特发性脊柱侧凸(AIS)是一种发生于青春期累及脊柱三个平面的脊柱畸形,发病机制未明。后路脊柱融合术(PSF)是目前治疗AIS应用最广泛的术式,但其术后并发症也逐渐引起了人们的重视,其中,畸形相关并发症如adding-on现象、近端交界性后凸、远端交界处后凸、冠状位失衡和双肩不平衡是AIS术后最常见的并发症,了解这些并发症的定义、诊断标准、发生率、自然史、危险因素和预防措施对于制定AIS的手术策略至关重要。本文对近年来关于PSF治疗AIS出现畸形相关并发症的最新研究进展进行了概述。

Deformity-related complications of posterior spinal fusion in the treatment of adolescent idiopathic scoliosis

Adolescent idiopathic scoliosis (AIS) is a spinal deformity involving the three planes of the spine during adolescence. The pathogenesis of AIS is still unknown. Pos terior spinal fusion (PSF) is a routine surgery that is most widely used to treat AIS. Its postoperative complications have gradually attracted people''s attention. Among those complications, adding-on phenomenon, proximal junctional kyphosis, distal junctional kyphosis, coronal imbalance and shoulder imbalance are the most common ones. Understanding the definition, diagnostic criteria, incidence, natural history, risk factors, and preventive measures of these complications is essential to make surgical strategies for AIS. This article reviews the latest research on the deformity-related complications of PSF in patients with AIS.
