A Retrospective Study of the Functional Outcomes in Patients with Proximal Humeral Bone Defect after Shoulder Fusion or Prosthetic Replacement.

Shoulder arthrodesis is a reliable reconstructive procedure in patients with large bone defects after the resection of proximal humeral tumors for pediatric osteosarcoma patients. Moreover, prosthetic replacement with anatomical implants results in poor function in older metastasis patients with large bone defects and resection of the deltoid muscle.
