Abstract

The purpose of this study was to report the results following implantation of a total distal radioulnar joint prosthesis in five multioperated patients with posttraumatic or Essex-Lopresti injury. The range of motion (ROM) for flexion and extension, radial deviation and ulnar deviation of the wrist, and pronation and supination of the forearm, grip strength, pain intensity through a visual analog scale (VAS), surgical complications and ability to return to work, were recorded. Subjective and objective functions were assessed using the quick DASH questionnaire and the modified Mayo wrist score, respectively. The mean postoperative follow-up was 4.3 years. Average postoperative increase in ROM was 28.8° for flexion-extension; 2.2° for radial and ulnar deviation, and 18° for pronation-supination, reaching 85.8%, 85% and 80.8% of the contralateral hand function, respectively. Grip strength increased by 6.8kg, with recovery of 78% of the strength of the unaffected hand. VAS score decreased to a mean of 6.2 postoperatively. There were complications in two cases. All five patients showed no signs of implant loosening or movement. The quick DASH score decreased from a mean of 85 preoperatively to 38.6 postoperatively. The modified Mayo wrist score increased from a mean of 24 preoperatively to 73 at final follow-up. Four patients recovered their professional and daily activities without restriction and were satisfied with the procedure; one patient with heterotopic bone formation at the distal tip of the ulnar stem did not want any further surgery and agreed to job modifications.
