Proximal Row Carpectomy Combined with Wrist Hemiarthroplasty

Abstract

Proximal row carpectomy (PRC) combined with distal radius hemiarthroplasty is a relatively novel procedure that rivals total wrist arthrodesis and offers a new surgical treatment option for select patients with painful, end-stage wrist disease. We present our early experience with this procedure. A retrospective chart review was conducted for nonrheumatoid patients diagnosed with wrist arthritis and subsequently treated with wrist hemiarthroplasty combined with PRC. The minimum follow-up duration was 12 months. Preoperative and postoperative flexion, extension, and grip strength were recorded. Postoperative radiographic findings were assessed. The Patient-Rated Wrist Evaluation (PRWE) questionnaire was administered to gauge postoperative pain and function. The records of 10 patients were reviewed. The mean age was 64 years and the mean postoperative follow-up duration was 19 months. Postoperative flexion, extension, and grip strength were all found to be less than the preoperative levels. The mean postoperative PRWE score for pain and function were 26 and 23, respectively. The complications were diverse and occurred at a relatively high rate. PRC combined with distal radius hemiarthroplasty is a novel procedure that offers a potential surgical option for the treatment of wrist arthritis in select patients. Our early experience has lead us to modify our technique with regard to the implant material, and at this stage, the surgical technique and the most appropriate implant may require further optimization. The level of evidence for this study is IV (therapeutic).
