[Treatment of proximal humeral tumor: a case report].
In management of malignancy of the proximal humerus, amputation or a complete flail limb both give poor functional results. The limb-salvage procedure with joint reconstruction preserves function in the elbow and hand, thereby improving the quality of remaining life for patient. Prosthetic humeral replacement may avert amputation and preserve a functional arm, but neither segmental modular proximal humeral prosthesis nor custom-made prosthesis is readily available here. Combining the Neer II shoulder prosthesis and Kuntscher's nail with acrylic cement can replace the proximal humerus with an adjustable length of stem within the humeral shaft. A piece of mesh is incorporated into the prosthesis, placed around the neck of the Neer II shoulder prosthesis, and sutured to the rotator cuff to prevent subluxation of the humeral head and preserve some function of the rotator cuff. The above prosthetic humeral replacement has been applied to one patient with a primary osteosarcoma. It preserved the function of the elbow and hand well. One year post-operatively, there was no dislocation or subluxation. Details of procedures used are given.
