Locking plate fixation of proximal humerus fractures is known to have high complication rates. Even a technically well-performed surgery can be subject to loss of reduction, which can lead to an adverse functional outcome for the patient. In this case report, we describe a patient who underwent open reduction and internal fixation of a proximal humerus fracture complicated by delayed loss of reduction of a greater tuberosity fragment that was revised using arthroscopic techniques.
Arthroscopic repair of displaced greater tuberosity fragments after failed locking plate fixation of proximal humerus fractures can lead to good functional outcomes at 1-year follow-up.
肱骨近端骨折的锁定板固定已知具有较高的并发症发生率。即使手术技术操作良好，也可能出现复位丢失，从而导致患者的功能结果不佳。在本病例报告中，我们描述了一位接受肱骨近端骨折切开复位内固定术的患者，该患者发生了大结节骨块的延迟复位丢失，随后采用关节镜技术进行了翻修。
对于锁定板固定失败的肱骨近端骨折，采用关节镜修复移位的大结节骨块可在 1 年随访时获得良好的功能结果。
