We prospectively evaluated the clinical and functional outcomes of pronator teres to extensor carpi radialis brevis transfer in children with cerebral palsy. Patients were followed-up at 6 months postoperatively, and functionally assessed using the House classification, Manual Ability Classification System (MACS) and Upper Extremity Functional Index (UEFI). Fifteen children with a mean age of 8.1 years underwent tendon transfers. All patients were of Gschwind and Tonkin Grade 2 for pronation deformity; eight patients were of Zancolli’s classification Group 1 and seven, Group 2 for wrist flexion deformity. The average gain in active supination was 67°, and wrist extension 15°. An increase of 7.0 in the UEFI score was recorded, although no significant improvement in MACS and House classification was observed. We conclude that the pronator teres to extensor carpi radialis brevis transfer improves upper limb function through effective correction of forearm pronation and wrist flexion deformities.
