Thumb carpometacarpal osteoarthritis: arthrodesis compared with ligament reconstruction and tendon interposition.

BACKGROUND: There has been considerable controversy regarding the procedure of choice for treatment of any given stage of osteoarthritis of the thumb carpometacarpal joint. This study was designed to directly compare the clinical results of two common surgical procedures for this condition, trapeziometacarpal arthrodesis and trapezial excision with ligament reconstruction and tendon interposition, in similar patient populations. METHODS: Between 1988 and 1998, 109 patients (141 thumbs) who were less than sixty years old were treated with one of the two procedures. In a retrospective review, forty-two patients (fifty-eight thumbs) treated with arthrodesis completed an outcome questionnaire and twenty-nine patients (forty-four thumbs) treated with arthrodesis completed the questionnaire and were examined. In the group treated with trapezial excision with ligament reconstruction and tendon interposition, thirty-nine patients (forty-nine thumbs) completed the questionnaire and thirty patients (thirty-eight thumbs) completed the questionnaire and were examined. The average duration of follow-up was sixty-nine months. The groups were similar with regard to age, gender, hand dominance, and duration of follow-up. RESULTS: Subjective evaluation of pain, function, and satisfaction demonstrated no significant difference between the two groups, with >90% of patients satisfied following either procedure. Although grip strength did not differ between the groups, the arthrodesis group had significantly stronger lateral pinch (p < 0.001) and chuck pinch (p < 0.01). The group treated with ligament reconstruction and tendon interposition had a better range of motion with regard to opposition (p < 0.05) and the ability to flatten the hand (p < 0.0001). There was a higher complication rate in the arthrodesis group, with nonunion of the fusion site accounting for the majority of the complications. However, despite a persistent nonunion in six thumbs, those thumbs and the thumbs in which union was obtained did not differ with regard to pain; all of the patients with nonunion had improvement in their pain status compared with preoperatively, and all were very satisfied with the outcome. Peritrapezial arthritis developed in nine patients (fourteen thumbs). This finding was not related to age and did not affect overall pain, function, or satisfaction. CONCLUSIONS: Although traditionally arthrodesis and ligament reconstruction and tendon interposition have been indicated in two different patient populations, we compared them in a homogeneous group and found that the two procedures had similar results with regard to pain, function, and satisfaction despite minimal differences in strength and motion. Although complications were more frequent following arthrodesis, most did not affect the overall outcome.

Wrist arthrodesis with excision of the proximal carpal bones using the Ao/ASIF wrist fusion plate and local bone graft.

We present our series of 17 patients who underwent wrist arthrodesis with excision of the proximal row carpal bones using the AO wrist fusion plate and local bone graft obtained from the excised proximal carpal row. All patients were evaluated using a questionnaire to assess pain, function, ability to perform an occupation and satisfaction with the procedure. The mean follow-up was 17 months, at which time all the fusions had united. Clinical outcome scores showed that 14 and 15 of the 17 patients achieved good or excellent results with regard to their current condition and clinical improvement, respectively. Four patients required secondary surgery, two for fractures and two for instability of the distal radio-ulnar joint unrelated to the wrist fusion.

Myositis ossificans after a supracondylar fracture of the humerus in a child.

Myositis Ossificans After a Supracondylar Fracture of the Humerus in a Child. In addition to the better known complications of supracondylar humerus fractures, myositis ossificans is often listed as a less common complication. This complication is extremely rare in children and historically has been attributed to high-energy trauma, manipulation, surgical intervention, aggressive passive range-of-motion exercises, or associated head injury. We present a case report of a 3-year-old girl who developed myositis ossificans after a low-energy supracondylar fracture of the humerus despite having been treated without manipulation, surgery, or physical therapy. This report illustrates that supracondylar humerus fractures can be complicated by myositis ossificans despite the best attempts at prevention.
