The interval between injury and surgery was similar in both groups (<
12 days). Postoperative protocol and rehabilitation was the same in both groups. Full range of motion as tolerated was allowed two week after surgery. Active range of motion, Mayo Elbow Performance Score (MEPS), pain, strength (Dexter isokinetic testing), patient satisfaction, operative time and elbow radiographs were evaluated at 12 months postoperatively. The mean follow-up was 17 months (range, 12–34).
Open arthrolysis (column procedure) trough a lateral (72%) or posterior (28%) approach followed a minimum rehabilitation period of 6 months post original injury. In 8 cases, an anterior transposition of the ulnar nerve was required. Patients received postoperative analgesia with Bupivacaine 0,0125% trough an indwelling catheter. No chemical or radiotherapy ectopic calcification prophylaxis was used. Postoperative complications, range of motion, X-ray evaluation, time to return to work, activity level and workers’ compensation were evaluated at the end of follow-up (24 months, range 12–36).
In 20% of cases, patients returned to their previous job with some restrictions (33% disability) and 12% changed to a less physically demanding occupation.
We considered factors such as: systemic conditions, functional work requirement, preoperative time, surgical technique, and their correlation with complications, clinical outcome and time to return to work and activity level.
Postoperative complications, pain (visual analogue scale), clinical and functional outcome based on DASH score, grip strength, X-ray evaluation, time to return to work and activity level were evaluated and compared at 3, 6 and 12 months of prospective follow-up.
Thirty-eight patients were treated with scaphoid excision and 4-corner fusion using dorsal circular plate. Thirty-nine patients were treated with total wrist fusion using one single, dorsal, precontoured and tapered plate for osteosynthesis and third carpometacarpal joint (CMCJ-3) was included. All patients were immobilised in a cast for 4 weeks after surgery. Postoperative complications, pain (visual analogue scale), clinical and functional outcome based on Green and O’Brien score, grip strength, X-ray evaluation, time to return to work and activity level were evaluated and compared.
The average time to return to work was 17 weeks (4-corner) and 16,2 weeks (total fusion). All patients return to work. Twelve percent of four-corner fusion and 72% of total wrist fusion return to the same work level with restrictions (until 33% of activity). Twenty-two percent of 4-corner fusion and 28% of total wrist fusion were unable to return to their previous activity level, performing lower intensity work activities. Overall satisfaction was high in both groups with 85% (4corner) and 93% (total fusion).
Total wrist fusion had less surgical failures, better level of satisfaction, lesser lost of force than 4-corner fusion, with less potential for further deterioration with time. However, 4-corner fusion allows return to work with a similar activity level and preserve a functional range of motion in patients with high levels of activity.
Pain, mobility and radiograhs were evaluated and also strength (isokinetics), functionality (DASH score) and, finally, the return to work at 3, 6 and 12 months.
The patients were assessed clinically (modified Mayo wrist score) and radiograhically. The grip and pinch strength were also studied.
