Modified Steindler procedure for elbow flexion restoration.
The results of modified Steindler procedures for elbow flexion performed during the past 20 years were reviewed retrospectively. The modifications were designed to avoid the phenomenon of the patient having to make a fist in order to obtain elbow flexion (Steindler's effect). The flexor carpi ulnaris, the flexor carpi radialis, and the palmaris longus, along with a bone fragment, are transferred to the anterior aspect of the humerus. The muscles are carefully separated from the flexor digitorum superficialis, which is left in place. This avoids both flexion of the fingers and pronation. Indications are discussed, especially in brachial plexus reconstructive surgery. Steindler's procedure is indicated in upper plexus lesions (C5-C6); other transfers are more appropriate for lower plexus palsies. Results were assessed according to elbow flexion against resistance. Flexion over 120 degrees when lifting 3 kg was rated very good. Of 32 modified Steindler procedures reviewed, 18 were rated very good, 8 good, 4 fair, and 2 poor.
