An investigation on the use of an allograft composite in reverse shoulder arthroplasty for revision of a failed arthroplasty – conducted at the Florida Orthopaedic Institute and the Foundation for Orthopaedic Research and Education, both in Tampa – has garnered a number of honors this year:
- In March, to Jacob Cox, MD, a resident in orthopaedic surgery at the University of South Florida in Tampa (Class of 2019), was selected to present the paper, “Clinical Outcomes Following Reverse Shoulder Arthroplasty-Allograft Composite for the Revision of Failed Arthroplasty Associated with Proximal Humeral Bone Deficiency: 2- to 15-Year Follow-Up,” at the podium during the annual meeting of the American Academy of Orthopaedic Surgeons in New Orleans.
- In June, Paul B McLendon, MD, a 2012 graduate of Florida State University College of Medicine in Tallahassee and currently a fellow in orthopaedic shoulder and elbow surgery with the Florida Orthopaedic Institute, won the Robert H. Cofield Award. This award is given at the ASES Fellows Symposium, held in conjunction with the San Diego Shoulder Institute’s annual course, for the best research project by a fellow.
- Also in June, Dr. Cox won first place in the resident research competition at the 2018 Annual Meeting of the Florida Orthopaedic Society in St. Petersburg. The award is given to the research determined to be the best project undertaken by a current orthopaedic resident.
The study reports on a cohort of patients with proximal humeral bone loss who were treated with a reverse shoulder allograft-prosthetic composite following failure of anatomic shoulder arthroplasty. These patients generally present with significant pain and loss of shoulder function. Unfortunately, few options are available for reconstruction
At an average follow-up of 67 months, 70% of patients who received the allograft-prosthetic composite reported good to excellent results, 17% reported satisfactory results, and 13% reported unsatisfactory results. The researchers saw improvement in functional outcome scores and range of motion in forward flexion and abduction.
The reoperation-free survival rate of all reconstructions was 88% at 5 years, 78% at 10 years, and 67% beyond 10 years. Humeral-sided revision-free survival was 94% at 5 years, 89% at 10 years, and 75% beyond 10 years.
The researchers concluded that a reverse total shoulder allograft-prosthetic composite is a durable and effective option for managing patients with proximal humeral bone loss.
