Superior capsular reconstruction (SCR) is an emerging surgical technique used to treat patients with irreparable rotator cuff tears. In this procedure, a graft is attached between the superior glenoid and the greater tuberosity, with the aim of optimising glenohumeral joint function and stability. Pre-operative radiological evaluation of patients having such cuff tears is crucial for appropriate patient selection. Such imaging is particularly useful for the assessment of the cuff tear size and location, muscle wasting, fatty infiltration and the presence of any glenohumeral joint arthritis. In addition, post-operative imaging is useful in assessing graft integrity, with specific patterns of graft failure now being recognised on imaging. This article will discuss the indications and contraindications for this procedure, and review the biomechanical concepts of SCR in improving glenohumeral joint stability and restoring the force couples around the joint. The radiological appearances of the intact graft and the various patterns of graft failure will be illustrated, along with various radiological examples.
上盂唇前后部重建术
上盂唇前后部重建术（SCR）是一种新兴的手术技术，用于治疗不可修复的肩袖撕裂患者。在该手术中，将移植物固定在盂上缘和大结节之间，目的是优化盂肱关节功能和稳定性。对于接受此类肩袖撕裂治疗的患者，术前的影像学评估至关重要，有助于进行适当的患者选择。这种影像学检查对于评估肩袖撕裂的大小和位置、肌肉萎缩、脂肪浸润以及盂肱关节关节炎的存在特别有用。此外，术后影像学检查有助于评估移植物的完整性，目前在影像学上已经认识到特定的移植物失败模式。本文将讨论该手术的适应证和禁忌证，并回顾 SCR 改善盂肱关节稳定性和恢复关节周围力偶的生物力学概念。将说明完整移植物的影像学表现和各种移植物失败模式，并提供各种影像学示例。
