The aim of this study was to assess factors associated with long-term patient-reported functional, pain, and satisfaction scores in patients who underwent (Bowers) hemiresection interposition technique (HIT) arthroplasty of the distal radioulnar joint (DRUJ). The secondary aims were to determine the complication and reoperation rates. A retrospective study with long-term follow-up of patients undergoing HIT arthroplasty was performed. Demographic, disease, and treatment characteristics were collected for the 66 included patients. Thirty-one patients completed all surveys, which were the Quick Disabilities of Arm, Shoulder and Hand (QuickDASH), our custom-made HIT arthroplasty questionnaire, Numeric Rating Scale (NRS) for pain, and NRS for satisfaction. The mean interval between surgery and follow-up by means of questionnaires was 8.6 ± 3.4 years. The mean QuickDASH score was 31.0 ± 20.2. The mean score of the HIT arthroplasty questionnaire was 2 ± 2. The median NRS for pain was 1 (interquartile range [IQR], 0-3), and the median NRS for satisfaction was 9 (IQR, 8-10). The complication rate and reoperation rate were 14% and 8%, respectively. Overall, patients expressed satisfaction with HIT arthroplasty, despite a mean QuickDASH score of 31.0. In our cohort, patients with inflammatory arthritis had higher satisfaction and lower pain scores. Patients who had prior trauma, prior surgery, or DRUJ subluxation are generally less satisfied. Men, older patients, and posttraumatic patients had higher long-term pain scores; however, posterior interosseous nerve neurectomy is associated with improved pain scores. Our findings support the use of HIT arthroplasty in patients with inflammatory arthritis.
