Abstract

We studied the results of tibialis posterior (TP) tendon transfer through the interosseal membrane in patients affected with a deficit in the common peroneal nerve (CPN). Patients underwent a clinical, radiographic and electromyographic (EMG) examination before surgery. In recent cases dynamic EMG and computerized gait analysis were also performed. At follow-up we evaluated all patients with a computerized gait analysis and dynamic EMG. We noticed a decrease in passive and active mobility after surgery. There was progressive increase in the average walking speed to physiological values. Step length, average speed of the foot and duration of the step reached physiological values after surgery. Dynamic EMG at follow-up showed continuous basic activity, with two activity peaks. The first was similar to the natural activation of the TP. The second coincided with ankle dorsiflexion in the final part of the swing phase. The presence of a continuous activity of the muscle during walking is a confirmation of the muscle function at least partially as a tenodesis. In two patients the tendon never functioned after the transfer.
