Refixation of muscular insertions after endoprosthetic replacement of the proximal humerus.
We describe the refixation of muscle insertions after resection of the proximal humerus in tumor patients. The prosthesis specially designed for this purpose carries large drill holes in the places corresponding to the anatomical sites of the muscle insertions. The muscles are attached to the prosthesis by means of tendon strips from the fascia lata. This can be expected to produce better functional results and to prevent subluxation.
