Event Description

It was reported per a journal article from current orthopaedic practice (2020) that reported a study from the united states that looked at the use of a modular endoprosthetic reconstruction system with a reverse total shoulder arthroplasty for massive proximal humeral bone loss.The purpose of the study was to evaluate the preliminary outcomes of reconstruction with this device in patients with massive proximal humeral bone loss.The study reviewed twelve (12) patients with massive (>4cm) proximal humeral bone loss who had reconstruction with a reverse total shoulder arthroplasty using a single modular endoprosthetic system (comprehensive segment revision system, zimmer biomet).A standard deltopectoral approach was utilized, and all but one of the prostheses were press-fit; the other was cemented because of poor bone quality.The indication for revision was proximal humeral fracture (2), tumor (3), infection (3), gorham disease (1), and failed arthroplasty (3).The study population had a mean age of 62.8 years at time of surgery (range 22-79 years).Average follow-up was 2.1 years (range 1-3.1 years).The study reported one patient experienced grade ii scapular notching.No further intervention was provided.
