Routinely-Collected Outcomes of Proximal Row Carpectomy

Abstract

To describe patient-reported pain and function 12 months after proximal row carpectomy (PRC). Secondary outcomes included return to work, grip strength, range of wrist motion, satisfaction with treatment results, and complications. This cohort study was part of the British Society for Surgery of the Hand Studyathon 2021, using ongoing routinely-collected data of 304 eligible patients who underwent PRC (73% scapholunate advanced collapse, 11% scaphoid nonunion advanced collapse wrist; 11% Kienböck, 5% other indications) from Xpert Clinics, the Netherlands between 2012-2020. The primary outcome was the Patient Rated Wrist/Hand Evaluation total score (range, 0-100, lower scores indicate better performance). Of the 304 patients, the primary outcome was available in 217 patients. The total Patient Rated Wrist/Hand Evaluation score improved from 60 (95% confidence interval [CI], 57-63) to 38 (95% CI, 35-41) at 3 months, and 26 (95% CI, 23-29) at 12 months. The pain and function subscales improved by 18 (95% CI, 17-20) and 16 (95% CI, 14-18) points, respectively. At 12 months, 82% had returned to work at a median time of 12 (95% CI, 9-14) weeks following PRC. Grip strength did not improve. Wrist flexion and extension demonstrated a clinically irrelevant decrease. Satisfaction with treatment result was excellent in 27% of patients, good in 42%, fair in 20%, moderate in 6%, and poor in 5%. Complications occurred in 11% of patients, and conversion to wrist arthroplasty occurred in 2 patients. A clinically relevant improvement in patient-reported pain and function was observed at 3 months after PRC, with continued improvement to 12 months. These data can be used for shared-decision making and expectation management. Therapeutic IV.
