The purpose of this study was to analyze resultsof the long head of triceps transfer for active elbowflexion restoration in children with arthrogryposis. Materials and Methods. 29 patients with lack of active elbow flexion aged from 10 months to 15 years were examined and treated in Turner Scientific and Research Institute for Children’s Orthopedics from2008 to 2014. The relation between potential donormuscle condition and the level of segmental spinalcord lesions was determined on the basis of clinical,neurological, physiological and ultrasound examina-tions. 35 transpositions of long head of the triceps in29 children were performed (17 - with mobilizationand 18 - without mobilization of the elbow). Results and Conclusion. Analysis of long-termresults of long head of triceps transposition as a ped-icle flap in patients with arthrogryposis has shown theeffectiveness of restoration of active forearm flexion.Good results were noted in 35 %, satisfactory in 35 %and pure in 30 % of cases in the series.
