Treatment of Scapular Chondrosarcoma with a 3D-Printed Implant and Reverse Total Shoulder Arthroplasty: Case Report
Abstract
Chondrosarcomas are malignant, cartilage-producing tumors most commonly arising in the pelvis, femur, and humerus; involvement of the scapula is rare. Surgery is the primary treatment for nonmetastatic disease. Compared with pelvic chondrosarcoma, scapular lesions generally have a better prognosis because the regional anatomy allows wide local resection with negative margins.We report a case of glenoid chondrosarcoma in a 47-year-old man treated with tumor resection and reconstruction using a 3D-printed implant combined with reverse total shoulder arthroplasty. The rationale for presenting this case is its low incidence. The proposed surgical approach—including deltoid detachment—provided adequate exposure while protecting neurovascular structures. Reconstruction of the osseous defect with a 3D-printed implant and reverse shoulder arthroplasty facilitated recovery of shoulder motion and yielded good functional outcomes.Downloads
