Neglected rupture of the Achilles tendon treated with peroneus brevis transfer: a functional assessment of 5 cases

The purpose of this study was to review the clinical results of 5 patients who underwent repair of a chronic Achilles tendon rupture using a combination of peroneus brevis transfer and plantaris tendon augmentation. The technique belongs to the group of local tendon transfer procedures making use of the transferred peroneus brevis tendon as strengthening material together with the plantaris tendon as suturing material. There were 4 males and 1 female with an average age of 49.4 years and an average time to presentation postinjury of 19.8 weeks (range 5-40 wk). All patients underwent Cybex strength testing before and approximately 1 year after surgery. This testing demonstrated a postoperative improvement in peak plantarflexion torque (Newton- meters/body weight) in all cases. The peak torque of plantar flexion increased in all patients (range, 21%-410%). Four patients were found to have an increase of the dorsal flexors peak torque (range, 31%-290%), whereas one patient showed a decrease (-37%). No patient experienced wound closure complications, postoperative pain, or functional limitations. In spite the possibility of residual lateral ankle instability, we found this modification to be a valuable innovation that offers a very good functional result, low morbidity, technical advantages to the surgeon and, most important, a durable and satisfactory result for the patients.
