Partial ulnar head replacement : Eclipse® prosthesis : a multicentric review of 27 patients

Abstract : Purpose : Treatment options of distal radioulnar joint (DRUJ) disorders consist of ulnar resection, the Bowers or the Kapandji-Sauvé procedure. However these nonanatomic procedures lead to a lot of complications like decreased grip, persistent pain and instability of the DRUJ as the "ulna impingement syndrome". This multicentric study reports experience of several surgeons treating DRUJ disorders using a partial ulnar head prosthesis. Method : Twenty-seven wrists in 27 patients (20 females, 7 males) were treated for painfull DRUJ disorders secondary to postraumatic arthrosis (7cases), idiopathic arthrosis (13 cases), inflammatory diseases (6 cases) and congenital disease (1 case) with an Eclypse prosthesis (Bioprofile, Grenoble, France). The mean follow-up is 30 months. Post-operative assessments included pain score, satisfaction, forearm range of motion, grip strength, clinical and radiographic examination. The DASH score and the Mayo Wrist Score (MWS) was calculated. Results : The mean pain score decreased from 6 preoperative to 1,7 postoperative and 24 patients were very satisfied and satisfied. The mean pronation was 83,3°, supination 64°, extension 58,1° and flexion 56,4°. Average grip strength was 14kg or 102% of the opposite side. The mean DASH score was 26,3 and the mean MWS was 76,8 with 16 excellent and good results. All wrists were clinically stable. One revision occured at 22 months and one patient had a distal migration of the prosthesis. Conclusion : Eclypse prosthesis seemed to be a good option for treatment of DRUJ disorders with a low rate of complication. Larger clinical study will needed to determine the long-term sucess of Eclypse prosthesis.
