Clavicle fracture after reverse total shoulder arthroplasty: a case report with literature review.

In reverse total shoulder arthroplasty, retensioning of the deltoid muscle is essential for regaining active elevation. However, the procedure remains problematic, in that it may potentially produce complications not only because it is a complex procedure but also because it causes anatomical changes. We experienced a rare case of a 64-year-old woman presenting with non-traumatic clavicle fracture after reverse total shoulder arthroplasty via a deltopectoral approach. In our case, the patient presented with pain in the clavicle area, which worsened during joint movement. Therefore, surgeons should consider the possibility of clavicle fracture in patients presenting with pain in the clavicle area which worsens.
