“…The overall experience with different designs during the last three and a half decades strongly indicates there are specific criteria to optimize the clinical results [19]. Distal component fixation should primarily be within the carpus rather than relying on the metacarpal canals.…”

“…In patients who have adequate bone quality, fixation by osteointegration rather than cement would seem to be a better choice for both components to improve durability and reduce bone destruction if revision is necessary. The articulation should be broad, generally ellipsoidal in shape, and semiconstrained [19]. It should also resist imbalance and instability yet provide a functional range of motion that can be achieved early with minimal formal rehabilitation.…”

“…The increased radial component width provides greater capture of the carpal component, thus conferring greater rotational stability. 9 Early results with the Universal 2 prosthesis have been encouraging, with no episodes of dislocation, implant loosening, or revision. 8,10 We report outcomes of 21 TWA using the Universal 2 prostheses.…”

purpose. To report outcomes of 21 total wrist arthroplasties (TWA) using the Universal 2 prosthesis. Methods. Five men and 14 women aged 44 to 82 (mean, 62) years underwent 21 total wrist arthroplasties for rheumatoid arthritis (n=19) and post-traumatic arthritis (n=2) by a single surgeon using the Universal 2 prosthesis. Pre-and post-operative pain and function were assessed by a single surgeon using the Disabilities of the Arm, Shoulder and Hand (DASH) score and the patient-rated wrist evaluation (PRWE) score. Range of motion, stability, dislocation rate, and neurovascular status were also assessed. Radiographs were evaluated for implant alignment and fit, screw positioning, and implant loosening. results. The mean time to assessment of the range of motion was 3.1 (range, 1.8-3.9) years, and the mean time to assessment of the PRWE score was 4.8 (range, 2.1-7.3) years. The range of motion in each direction and the mean DASH and PRWE scores improved significantly following TWA. Two patients Total wrist arthroplasty using the Universal 2 prosthesis 2012;20(3):365-8 had restricted range of motion, which was treated by manipulation under anaesthetic (after 6 months in one and 8 weeks in the other). One patient underwent excision of a palmar bony bridge. One patient endured extensor pollicis longus rupture and underwent tendon transfer after 5 months. Radiographs revealed no evidence of implant loosening, migration, or malalignment. There was no sign of osteonecrosis in the remaining carpals or metacarpals. conclusion. The Universal 2 TWA achieved significant improvement in range of motion and functional outcome of the wrist, with reduced rates of early joint instability, dislocation, and implant loosening, compared to previous implants. The small implant size and cementless design reduce bone loss and osteonecrosis. Journal of Orthopaedic Surgery

“…Eine oberflächliche und 2 tiefe Infekionen wurden beobachtet. Bei einer Komplikationsrate von 32 % (12 Patienten) bestand bei 5 Patienten eine Luxation nach palmar, ein Problem, das wir ebenfalls bei der UTW-I-Prothese beobachteten und das durch die Entwicklung der UTW-II-Prothese mit Wechsel der Inlayform von einem Torus zu einem Ellipsoid und Vergrößerung der radialen Kontaktfläche behoben wurde [7].…”

Total wrist arthroplasty. Outcome of the UTW prosthesisAbstract Total wrist arthroplasty is an option to wrist arthrodesis in the treatment of irreversible wrist destruction. The universal total wrist prosthesis (UTW) was developed by Menon in 1988 and, since 2003, an improved version (UTW II) is available. From 2001 until 2007, 9 patients with degenerative or post-traumatic osteoarthritis of the wrist were treated with an UTW-prosthesis. The mean follow-up was 3 years. Mean pain relief improved from 8 points preoperative to 2 points postoperative on a visual-based analogue scale. The mean DASH score is 48 (± 29) at follow-up. The mean range of motion is 60°. Complications included a luxation of the prosthesis and an extensor tendon rupture. Component loosening was not observed. Total wrist arthroplasty is not a standard procedure. The UTW-prosthesis is a modern unconstrained wrist arthroplasty. Observing differentiated and strict indications and having careful operative technique, a good or very good outcome can be achieved with the UTW-prosthesis.
