Isolated deltoid paralysis is a rare pathology that can occur after axillary nerve injury due to shoulder trauma or infection. This condition leads to loss of deltoid function that can cause glenohumeral instability and inferior subluxation, resulting in rotator cuff muscle fatigue and pain. To establish dynamic glenohumeral stability, a novel technique was invented. Humeral suspension is achieved using a double button implant with non-resorbable high strength cords between the acromion and humeral head. This novel technique was used in two patients with isolated deltoid paralysis due to axillary nerve injury. The results indicate that the humeral suspension technique is a method that supports centralizing the humeral head and simultaneously dynamically stabilizes the glenohumeral joint. This approach yielded high patient satisfaction and reduced pain. Glenohumeral alignment was improved and remained intact 5 years postoperative. The humeral suspension technique is a promising surgical method for subluxated glenohumeral joint instability due to isolated deltoid paralysis.
孤立性三角肌麻痹是一种罕见的病理情况，可在因肩部创伤或感染导致腋神经损伤后发生。这种情况会导致三角肌功能丧失，进而引起盂肱关节不稳定和下方半脱位，导致肩袖肌群疲劳和疼痛。为建立动态盂肱关节稳定性，发明了一种新技术。使用双纽扣植入物并在肩峰和肱骨头之间连接不可吸收的高强度绳索来实现肱骨悬吊。该新技术应用于两名因腋神经损伤导致孤立性三角肌麻痹的患者。结果表明，肱骨悬吊技术是一种有助于使肱骨头中心化并同时动态稳定盂肱关节的方法。这种方法获得了较高的患者满意度并减轻了疼痛。盂肱关节对线得到改善，术后5年保持完好。肱骨悬吊技术是治疗因孤立性三角肌麻痹导致的盂肱关节半脱位不稳定的一种有前景的手术方法。
