Objectives/Interrogation: Since elbow extansion is a passive movement when shoulder is adducted and at secondary importance compairing elbow flexion, muscle transfer to triceps is not commonly mentioned in obstetrical palsy literature.This need was observed specially in patients whom had improved shoulder abduction with surgery but have limited elbow extansion.
Methods: Previously, we had operated on 13 patients with elbow extansion restoration ages between 5-16 years. We used brachioradialis muscle in 6 patients, brachialis muscle in 6 patients and posterior deltoid muscle in one patient with pros and cons of each method.
Later on depending on the anatomic studies for lower trapezius transfer in order to have better shoulder external rotation, we used ipsilateral lower trapezius muscle by elongation with tensor fascia lata graft to triceps muscle, in 15 obstetric palsy cases.
Results and Conclusions: Average elbow extansion was improved 50 degrees and shoulder abduction was improved 35 degrees in our patients.Ipsilateral lower trapezius transfer is a good tecnique for triceps function restoration with minimal donor site morbidity.
