Biceps tendon rerouting and percutaneous osteoclasis in the treatment of supination deformity in obstetrical palsy.

Paralytic supination deformity of the forearm, secondary to obstetrical palsy, was treated by biceps tendon rerouting in 11 children. In two patients additional pronation was obtained by subsequent percutaneous osteoclasis and rotation of the radius and ulna. Correction of the supination deformity resulted in improvement of single-handed as well as two-handed activities in all patients.
