Abstract
BACKGROUND: Scant data are published about different available therapeutic options for restoration of active elbow flexion in arthrogryposis with varying degrees of improvement. In this retrospective study we evaluated medium-term effects of bipolar latissimus dorsi transfer in patients with arthrogryposis. METHODS: Pedicled latissimus dorsi bipolar muscle transfer was used to restore elbow flexion in 11 patients (13 limbs) with arthrogryposis. Elbow and shoulder range of motions and strength of elbow flexion were measured preoperatively and at the last follow-up. The functional use of the upper limb was examined by observation of activities of daily living and presence of adaptive mechanisms. General satisfaction was assessed at the final follow-up. RESULTS: The patients were a mean age of 5.69 ± 2.49 years. The follow-up period was 27.31 ± 17.8 months. At the last examination, according to transferred muscle function and elbow range of motion, function of 12 limbs was graded as excellent and good, and 1 was graded poor. The active postoperative elbow range of motion was 97.7° ± 34.5°. The general satisfaction of the patients with the surgical results was 92.3%. Activities of daily living were improved in 10 of 13 limbs, but adaptive mechanisms were detected in all patients except 2 at the last follow-up. CONCLUSIONS: We suggest pedicled bipolar latissimus dorsi transfer as a reliable therapeutic option to restore active elbow flexion in arthrogryposis with acceptable results regarding regaining range of motion and patient satisfaction. Functional passive elbow range of motion and good quality of latissimus dorsi muscle preoperatively is mandatory.
