Abstract:
Surgical principles in sarcoma are a wide resection, including surrounding tissues and maximisation of the function of the affected limb. Rotator cuff muscles are biomechanically important structures acting as a force couple in movement of the shoulder joint. Thus, conjoined tendons are essential for motion capability in absence of the supraspinatus muscle. This article reports a case of a large undifferentiated pleomorphic sarcoma (UPS) at the suprascapular fossa in a 78-year-old man. After diagnosis of sarcoma, he underwent wide, en-bloc excision preserving conjoined tendons of rotator cuff muscles and low-dose radiation therapy for surveillance of local recurrence. All dissection was performed to avoid contaminating the tumour and involved the whole supraspinatus except the conjoined tendons. We report a case of UPS at the suprascapular fossa, which showed a good result after a wide resection preserving conjoined tendons of rotator cuff muscles. Level of Evidence: Level V (Therapeutic).
摘要:
肉瘤的手术原则是广泛切除,包括周围组织和受影响肢体功能的最大化。肩袖肌肉是在肩关节运动中充当力偶的生物力学重要结构。因此,在没有冈上肌的情况下,联合肌腱对于运动能力至关重要。本文报道了一名78岁男性肩胛骨上窝大型未分化多形性肉瘤(UPS)的病例。诊断为肉瘤后,他经历了广泛的,保留肩袖肌肉联合肌腱的整块切除和低剂量放射治疗以监测局部复发。进行所有解剖都是为了避免污染肿瘤,并且涉及整个冈上肌,除了连筋。我们报告一例肩胛骨上窝的UPS,在广泛切除保留肩袖肌联合肌腱后显示出良好的效果。证据等级:V级(治疗)。
