AbstractBackgroundIn orthopedic oncology, total scapulectomy is necessary to allow a wide resection of extended malignancies of the scapula and scapular girdle. Scapular reconstruction is challenging even for the most experienced surgeon. This paper reports our experience with total scapular resections, followed by humeral suspension or custom-made prostheses.MethodsIn this retrospective study, we evaluated all the oncologic patients treated in our institution between 2016 and 2023 with total scapulectomy and consequential reconstruction using humeral suspension or a custom-made prosthesis. Only cases suffering from malignant bone tumors were included. The postoperative functionality of the treated limbs was assessed using the Musculoskeletal Tumor Society (MSTS) scoring scale. Complications and local recurrences were also recorded.ResultsNine patients were enrolled. Five had custom-made implants, and four had humeral suspensions. The mean postoperative MSTS score of patients treated with custom-made prostheses was 24.0 (22–26). Globally, our cohort’s mean MSTS score was 19.1 (9–26). Patients with custom-made prostheses had significantly better functional outcomes (MSTS 24 vs 13) and similar complication rates (40% vs 50%) than those who received humeral suspensions.ConclusionOur outcomes suggest that, when feasible, custom-made scapular prostheses can represent a reliable reconstructive option after total scapulectomy for malignant scapular tumors.
