Radiographic Prevalence Of Osteoarthritis Of The Scaphotrapeziotrapezoid Joint In Patients With Carpometacarpal Osteoarthritis Of The Thumb: A Retrospective Case Series, Charlotte E. Orr, Robert Mercer, Deana M. Mercer, Drew K. Newhoff, Matthew D. Martin, Moheb S. Moneim

UNM Orthopaedic Research Journal

Background: In planning operative treatment of thumb carpometacarpal (CMC) joint osteoarthritis, surgeons should consider the presence of an arthritic scaphotrapeziotrapezoid (STT) joint. We aimed to determine the radiographic prevalence of concomitant (STT) osteoarthritis with thumb CMC osteoarthritis in patients who underwent surgical treatment at our institution. We hypothesized that the prevalence of concomitant arthritis at these 2 joints (STT and CMC) would be lower than previously reported.

Methods: Between September 2005 and July 2012, a total of 417 patients were identified from our institution using the Current Procedural Terminology code for thumb CMC joint arthroplasty (25447). After applying exclusion criteria …

Total Ankle Replacement, Then And Now: A Review, Katherine J. Gavin

UNM Orthopaedic Research Journal

Total ankle replacement (TAR) for treating end-stage osteoarthritis of the ankle joint has been evolving since the early 1960s. Increased understanding of the biomechanics and kinematics of the foot and ankle, postoperative results of implant use, and advances in technology have led to improved implant designs and treatment outcomes. The current study reviews associated historical perspectives, kinematics, biomechanics, patient selection, imaging procedures, modern surgical techniques, postoperative complications, and comparison studies with arthrodesis to help evaluate TAR in successfully treating osteoarthritis of the ankle joint. Although arthrodesis remains the gold standard for treatment, findings of new studies have suggested that TAR …
