Abstract：
We report the 5-year outcome of an isolated, atraumatic full-thickness infraspinatus myotendinous junction tear treated with open surgical repair. The index patient developed severe pain and weakness in external rotation strength following a subacromial corticosteroid injection. Magnetic resonance imaging and ultrasound of the shoulder demonstrated a full-thickness myotendinous junction tear with extensive muscle edema, mild atrophy and a spinoglenoid notch varix. Due to persistent, worsening pain and presence of ER weakness, the patient underwent primary infraspinatus muscle-tendon repair with allograft augmentation via an arthroscopic-assisted open posterior approach. The patient had an uneventful postoperative course with a resolution of pain and improvement in ER strength, which is maintained at the latest 5-year follow-up. This case report highlights a favorable long-term outcome of an isolated infraspinatus myotendinous junction tear treated with primary muscle-tendon repair and dermal allograft augmentation.
摘要：
我们报告了一个孤立的5年结果，无创伤的全层冈下肌腱连接部撕裂，并进行开放手术修复。肩峰下注射皮质类固醇后，该索引患者出现严重疼痛和外部旋转力量无力。磁共振成像和肩部超声显示肌腱交界处全层撕裂伴广泛的肌肉水肿，轻度萎缩和棘锥样切迹静脉曲张。由于坚持不懈,恶化的疼痛和ER无力的存在，患者通过关节镜辅助的开放后入路接受了原发性冈下肌腱修复和同种异体移植.患者术后过程平稳，疼痛缓解，内质网强度改善，在最近的5年随访中保持不变。此病例报告强调了通过原发性肌腱修复和同种异体真皮移植增强治疗的孤立性冈下肌肌腱连接撕裂的长期有利结果。
