Transposition of the pronator radio teres muscle to the radial extensors of the wrist, in infantile cerebral paralysis. An improved operative technique.

In the majority of cases of infantile cerebral paralysis, the upper limb is found to be in an attitude of pronation of the forearm, flexion and adduction of the wrist, and flexion of the fingers. The modified surgical technique practiced by the writers enables the pronation of the forearm and the flexion of the wrist to be corrected at the same time, by transposing the pronator teres muscle to the radial extensors of the wrist after passing it around the radius through the interosseous membrane, thus giving it a supinating action.
