AbstractThe arthrotically destroyed distal radioulnar joint will lead to painful limitation of forearm rotation. Alternative treatment options are the hemiresection-interposition arthroplasty or the Kapandji-Sauvé procedure. The aim of our study was to evaluate the clinical and functional results following the hemiresection-interposition arthroplasty in non-rheumatoid patients. The most common posttraumatic cause of the arthrosis was the malunited distal radius fracture. In a retrospective study we examined 36 of 51 patients with a mean age of 53 years after an average follow up of 34 months clinically, radiologically and using the DASH questionnaire. The average preoperative pain measured 7.8 on the visual analog scale and was reduced statistically highly significant (p < 0.01) to 3.9. Whilst pronation increased statistically not significantly from a mean of 74 degrees to 76 degrees (p = 0.428), supination improved significantly from 54 degrees to 69 degrees (p - 0.012). The average grip strength increased statistically highly significant (p<0.001) from 40% to 64% compared to the unaffected side. Patients' satisfaction with the result averaged 6.9 on a visual analog scale. Using a modified Mayo-wrist score, six patients were rated to have an excellent, eleven patients a good, ten patients a satisfactory and four patients a poor result. The average DASH score measured 35. In 21 patients radioulnar impingement was found. This appeared to be painful in 14 patients and required revision surgery using the ulnar head prosthesis in five patients. In three patients, secondary ulnar shortening had to be performed due to a remaining painful impaction of the distal ulna against the lunate and triquetrum. Comparing our clinical results with the reported results following the Kapandji-Sauvé procedure from the literature, there was no evident superiority of either of the procedures. There is a need for a functional evaluation following the Kapandji-Sauvé procedure to compare the remaining functional impairment following both procedures. In conclusion both procedures have to be classified salvage procedures and therefore the indication should be limited to the arthrotically destroyed distal radioulnar joint.
