Early experience with computer-assisted shoulder hemiarthroplasty for fractures of the proximal humerus: development of a novel technique and an in vitro comparison with traditional methods.

A computer-assisted technique was developed for treatment of 4-part proximal humeral fractures via a hemiarthroplasty and tuberosity fixation. This was compared with a standard traditional method in 7 pairs of cadaveric shoulders. The computer-assisted technique used preoperative computed tomography data and computer simulations of anatomic characteristics… CONTINUE READING
