Randomized comparison of tape versus semi-rigid and versus lace-up ankle support in the treatment of acute lateral ankle ligament injury.

PURPOSE: Functional treatment is the optimal non-surgical treatment for acute lateral ankle ligament injury (ALALI) in favour of immobilization treatment. There is no single most effective functional treatment (tape, semi-rigid brace or lace-up brace) based on currently available randomized trials. METHODS: This study is designed as a randomized controlled trial to evaluate the difference in functional outcome after treatment with tape versus semi-rigid versus lace-up ankle support (brace) for grades II and III ALALIs. The Karlsson score and the FAOS were evaluated at 6-month follow-up. RESULTS: One hundred and ninety-three patients (52% males) were randomized, 66 patients were treated with tape, 58 patients with a semi-rigid brace and 62 patients with a lace-up brace. There were no significant differences in any baseline characteristics between the three groups. Mean age of the patients was 37.3 years (35.1-39.5; SD 15.3). Ninety-five males (49%) were included. One hundred and sixty-one (59 + 50 + 52) patients completed the study through final follow-up; 32% lost at follow-up. In two patients treated with tape support, the treatment was changed to a semi-rigid brace because of dermatomal blisters. Except for the difference in Foot and Ankle Outcome Score sport between the lace-up and the semi-rigid brace, there are no differences in any of the outcomes after 6-month follow-up. CONCLUSION: The most important finding of current study was that there is no difference in outcome 6 months after treatment with tape, semi-rigid brace and a lace-up brace. LEVEL OF EVIDENCE: I.

Outcome of Kienböck's disease 22 years after distal radius shortening osteotomy.

Loading of the lunate in patients with Kienböck's disease and a negative ulnar variance provide the rationale for a radial shortening osteotomy. This osteotomy decreases forces transmitted from the radius to the lunate. We retrospectively reviewed 12 patients with Kienböck's disease who had 13 radial shortening osteotomies to ascertain whether the reported short- and medium-term results endured in the long-term. We evaluated nine osteotomies in nine of the 12 patients with a minimum of 16 years followup (average, 22 years; range, 16-31 years). Three patients died and one was lost to followup. For the nine patients, the range of motion was impaired compared with the normal side. Grip strength was on average 90% of the unaffected side. The average visual analog scale score for pain was 2.4 and the average Disabilities of the Arm, Shoulder, and Hand score was 14 at latest followup. In eight patients, the Lichtman classification of Kienböck's disease did not change at followup, but in three patients there was radiographic progression of the disease, which occurred during the first 10 years postoperatively. The medium- and long-term results therefore were comparable. We recommend radial shortening in stable wrists (Stage 3A or less) with a negative ulnar variance. The radius should be shortened to the level of the ulna, normally 4 to 6 mm, after which stable (plate) fixation should be performed under compression.

Long term results of surgical intervention for osteoarthritis of the trapeziometacarpal joint : comparison of resection arthroplasty, trapeziectomy with tendon interposition and trapezio-metacarpal arthrodesis.

Trapeziometacarpal osteoarthritis is a common entity, often bilateral and predominantly affecting postmenopausal women. In the case of failure of conservative treatment, surgery is a good option. The aim of this study was to compare three surgical procedures. 63 patients (74 thumbs) with osteoarthritis of the trapezio-metacarpal joint were surgically treated; 54 patients were seen for follow-up, 7 had died and 2 were lost to follow-up. The patients were stratified according to treatment; resection arthroplasty (the joint surface's of the metacarpal and the trapezium are resected) (18 thumbs), trapeziectomy with tendon interposition (17 thumbs) or trapezio-metacarpal arthrodesis (28 thumbs). Baseline characteristics were comparable in the three groups for mean age at operation, Eaton classification, left right distribution and dominant hands operated. The average follow-up was 13 years for the resection group, 8 years for the trapeziectomy group and 9 years for the arthrodesis group. No statistically significant difference between the three groups was found for the visual analogue pain and satisfaction scale, pain frequency nor DASH score. Patients in the trapeziectomy group had significantly less pain compared to the arthrodesis group (p=0.025). Statistically, radial abduction was significantly better after trapeziectomy compared to resection arthroplasty (p<0.01) or arthrodesis (p=0.01). There was no difference among the three groups in grip and tip pinch strength nor in pain on palpation. None of the patients in the trapeziectomy group needed a re-operation, one patient in the resection arthroplasty group had a re-operation, and 22 patients in the arthrodesis group had one or more re-operations for hardware removal or because of a complication. This study shows that the resection arthroplasty has equally good long term results compared to trapeziectomy combined with tendon interposition or arthrodesis. Resection arthroplasty is performed through a single incision and is technically simple. In our clinic resection arthroplasty is therefore the preferred technique for the treatment of osteoarthritis of the trapeziometacarpal joint.
