APSI scaphoid hemiarthroplasty - long-term results
ABSTRACT Objective: This study is aimed at evaluating the long-term results of proximal scaphoid hemiarthroplasty for post-traumatic avascular necrosis at this institution. Methods: Twelve patients who underwent this procedure were identified, and the mean follow-up time was 6.5 years (range: 5-8 years). All patients were male, with a mean age of 39 years (range: 28-55 years). In eight patients, the non-dominant limb was affected. The procedure was carried out through a dorsal approach and all patients underwent the same rehabilitation protocol. Cases were evaluated regarding complications, pain, range of motion, functional status (Mayo Wrist Score), and disability (QuickDASH Score). Results: No immediate post-operative complications, such as infection or dislocation of the implant, were observed. All patients presented with peri-implant osteolysis at follow-up, on a radiograph study. None of the patients was forced to abandon their previous professional activity, although about 50% required some type of adaptation at their workplace. The mean functional capacity was, according to the Mayo Wrist Score, of 67.5 points (range: 50-80), corresponding to a satisfactory degree of function. The QuickDASH disability score presented a mean of 25 (range: 3-47.7). Conclusion: The results of this series are in line with previously published studies about this technique. Hemiarthroplasty with a pyrocarbon implant is a safe technique for the treatment of post-fracture avascular necrosis of the scaphoid proximal pole. This technique allowed for satisfactory functional results at a mean follow-up of 6.5 years.
