Failed hemiarthroplasty revised to CTA prosthesis

Another interesting case from our OR yesterday. This patient had a hemiarthroplasty elsewhere for fracture. After this surgery, she has had weakness and instability. These plain films show non-union of the tuberosities and inferior as well as anterior instability.

Rather than trying to remove a cemented prosthesis from this fragile bone and convert this shoulder to a reverse, we elected to revise this loose and weak joint to a cuff tear arthropathy humeral head and attempt to achieve stability by upsizing the diameter and height of the head. This enabled us to restore stability with a good range of motion.

The patient has started active assisted rehabilitation and now has over 120 degrees of assisted elevation without instability and with increased comfort.
