The Usefulness of a Three-Dimensional Printed Segmental Scapula Prosthesis for Recovering Shoulder Function in a Patient with Scapula Chondrosarcoma: A Case Report.

Rationale: Localized chondrosarcoma of the scapula has a favorable long-term survival outcome. Therefore, recovery of shoulder function after surgery is important in middle-aged patients. Currently, three-dimensional (3-D) printing implants can be applied for personalized limb salvage surgery. Patient concerns: A 41-year-old woman with a palpable scapular area presented with shoulder pain for 3 months, which was aggravated during shoulder exercise. Diagnoses: Chondrosarcoma at left scapular (Malawer S1, Enniking II B, and grade II chondrosarcoma). Interventions: Wide excision for a localized chondrosarcoma at the infrascapular lesion was performed and the resected muscles around the scapula were repaired with a 3-D printed segmental scapula prosthesis for recovery of shoulder function. Outcomes: The affected shoulder achieved satisfactory function after operation using the 3-D printed segmental scapula prosthesis at 1 year 6 months after the operation. Lessons: The 3-D printed segmental scapula prosthesis is a useful method for shoulder functional recovery in patients with scapula chondrosarcoma.
