UNASSIGNED: Single surgeon, retrospective case series of surgical technique at major trauma centre in Scotland. A 2.0mm mini-fragment plate was secured to the humeral head to act as an intramedullary strut during fixation in complex proximal humerus fractures. Fracture union and neck-shaft angle were assessed radiologically, whilst range of motion and complication profiles were assessed clinically.
UNASSIGNED: Twelve patients were followed up for an average of 10 months post-operatively. All achieved bony union with a mean neck-shaft angle of 128°. Mean range of motion values were 100° forward elevation, 83° abduction, 60° internal rotation and 37° external rotation. Four patients required further surgical intervention- two for hardware prominence, one for adhesive capsulitis and one for subsequent rotator cuff failure. There were no cases of avascular necrosis or infection.
UNASSIGNED: This novel technique addresses the established biomechanical propensity of proximal humerus fractures to fail in varus collapse and screw cut-out. This method provides an alternative to arthroplasty in the most severe proximal humerus fractures and is readily adopted via standard orthopaedic kit.
■单身外科医生,苏格兰主要创伤中心手术技术的回顾性病例系列。在复杂的肱骨近端骨折的固定过程中,将2.0mm的微型碎片板固定在肱骨头上,用作髓内支柱。通过放射学评估骨折愈合和颈轴角度,同时对运动范围和并发症情况进行了临床评估。
■术后随访12例,平均10个月。所有都实现了平均颈轴角度为128°的骨性结合。平均运动范围值为100°向前仰角,83°外展,60°内旋和37°外旋。四名患者需要进一步的手术干预-两名患者需要硬件突出,一个用于粘连性囊炎,一个用于随后的肩袖故障。无血管坏死或感染病例。
■这项新技术解决了已确定的肱骨近端骨折在内翻塌陷和螺钉切除时失败的生物力学倾向。该方法在最严重的肱骨近端骨折中提供了关节成形术的替代方法,并且易于通过标准骨科套件采用。
