Comparison of Reconstructive Techniques following Oncologic Intraarticular Resection of Proximal Humerus

Description

This presentation, led by Alexander Athey, discusses the outcomes of various surgical reconstruction techniques for proximal humeral malignancies. The proximal humerus is identified as a common site for both primary and metastatic tumors in the upper extremity, necessitating surgical interventions that often involve complex resections, including the rotator cuff and deltoid muscle. Reconstruction aims to restore shoulder stability and motion, with historical options such as endoprostheses, hemiarthroplasty, and osteoarticular allografts having specific complications like subluxation and collapse.



Recent advancements focus on reverse shoulder prosthesis technology, which enhances stability without needing a functional rotator cuff. Athey’s study compares outcomes from 78 patients who underwent intraarticular resections, with reconstruction categorized into hemiarthroplasty and reverse techniques. The analysis reveals that reverse prosthesis users generally experienced better functional outcomes and greater ranges of shoulder motion compared to traditional methods. The findings indicate that while complications like subluxation were present, the incidence of revision surgeries post-procedure was low, particularly for reverse reconstruction techniques, suggesting they offer a superior option for patients undergoing surgery for proximal humeral malignancies.
