Reconstruction with constrained prosthesis after total scapulectomy.

Abstract

Scapular prosthetic replacement after total scapulectomy can result in oncologic salvage and good postoperative function with a low rate of complications. Ten patients who underwent constrained scapular prosthetic replacement after total scapulectomy between 2003 and 2009 were reviewed retrospectively. At a mean follow-up of 36 months, 2 patients died of their disease. One patient showed recurrence and metastasis. Complications, including dislocation and superficial wound infection, occurred in 2 patients. The mean Musculoskeletal Tumor Society 93 score was 23.2 of 30 points. High scores were achieved for most items except hand position; only 5 patients can raise their hands above their waist. The ranges of active shoulder abduction and forward flexion motion were 20° to 45° and 40° to 65°, respectively. All patients retained normal hand and elbow functions. Although there are limitations in the shoulder's active motion, reconstruction with a scapular prosthesis can provide oncologic salvage and result in good postoperative function with a low rate of complications.
