The following video illustrates the surgical technique for a proximal humerus allograft-prosthetic complex to manage ... read more ↘ humeral component loosening from bone loss.
First step is measuring the amount of bone loss either preoperatively though CT scans or intraoperatively. The proximal humerus allograft should be fashioned to proper height by creating a step-cut with appropriate amount of bone remaining medially.
The allograft humeral head is cut, cancellous bone is removed, and a step-cut is performed. Subscapularis tendon should be left on graft for anterior repair. Trial to confirm soft tissue balancing and range of motion. Bone loss can be measured by clamping trail at level of humerus.
The allograft is secured to the patient’s proximal humerus using multiple cerclage wires or plate as shown in the video, and the humeral stem is cemented into place. ↖ read less
