BACKGROUND: Although modular prosthesis is commercially available to meet requirements in most limb salvage surgeries, customized prosthesis is still needed. In contrast to traditional complicated procedures, rapid prototyping (RP) technique can directly manufacture customized @entity702 prosthesis. The objectives of this study were to describe the workflow of this technique and show the follow-up results of @entity1 . METHODS: Three @entity1 with clavicle @entity2828 ( @entity2828 ), scapular @entity2828 , and @entity530 (CS) were scanned by computer tomography (CT). The images were segmented and reconstructed for preoperative planning and prosthesis design. Then, the data of prosthesis were imported into an electron beam melting system to manufacture implants. These three @entity1 received prosthesis implantation after @entity5 excision. They were followed up to evaluate survival rate, functional outcome, and complications. RESULTS: All @entity1 were alive with no evidence of disease. The @entity85 Society (MSTS) scores were 93, 73, and 90  % for @entity1 with clavicle @entity2828 , scapular @entity2828 , and pelvic CS, respectively. No surgical complications including limb length discrepancy, @entity1349 , and implant breakage were observed in current study. CONCLUSIONS: Electron beam melting (EBM) is a useful method to directly manufacture customized @entity702 prostheses. It might improve the effectiveness of limb salvage surgery for @entity242 in unusual sites.
