Total humerus replacement with reverse shoulder design for non-oncologic indication: A case report

Reconstruction of large skeletal defects pose significant challenges for orthopedic surgeons, particularly in cases of chronic skeletal defects where the surrounding structures differ substantially from the original anatomical structures, further complicating management. A 54 year old male patient presented with a large skeletal defect after osteomyelitis surgery. The treatment of choice for this case was reconstruction using a total humerus megaprosthesis. The prosthesis was custom-designed with a reversed shoulder joint and a total elbow joint, which were 3D printed using CT-Scan imaging. A short-term follow-up revealed improvements for the patient in arm functionality and expectation-based satisfaction at 6 months post-surgery. Total humerus megaprosthesis joint replacement may be a promising option for treating chronic humeral defects. •Large bone loss of humerus after osteomyelitis is quiet rare•Total humerus replacement is not common procedure for non-oncologic indication•a modified design of total humerus implant with reverse shoulder could give a better result for patient.
