Implantation of cementless hemiarthroplasty and tuberosity reconstruction with transosseous points in multi-fragmented displacement fracture of the humeral head. Corrected the position of the humeral component without signs of overstuffing. The acromion-humeral distance between the lower edge of the acromion and the head of the humerus (in neutral rotation) is normal. An area of less than 7 mm, with the head rising, indicates insufficiency of the rotator cuff, in particular, the supraspinatus tendon.
Shoulder hemiarthroplasty is a procedure which only the humeral head is replaced with a prosthesis and the fractured bone is reconstructed. In a traditional shoulder hemiarthroplasty, the humeral head is replaced with a polished metal ball and stem. Such surgery is performed when the humeral head is severely fractured but the glenoid and rotator cuff are normal.
