Background: We would like to describe our experience with Peroneus Brevis flap in complicated Achilles
tendon re-ruptures with fringed stumps.
Methods: Eight patients with monolateral re-rupture of Achilles tendon were selected as eligible for
surgical repair with Peroneus Brevis flap. Patients’ outcome was evaluated clinically (ATRS and ROM),
functionally (Gait analysis) and MRI was performed before and after surgery.
Results: Effective coverage of tissue defect was reached in all patients. Functional assessment evaluation
results were registered in a follow-up time that ranged from 12 to 18 months. ATRS and ROM tests’ results
showed good functional recovery without functional limitations or subjective reports pain. Postoperative MRI showed no signs of inflammation or tissue gaps. Gait analysis showed a partial reduction of
performance in the affected side that did not affect patients’ quality of life.
Conclusions: In the presence of fringed stumps in Achilles tendon re-rupture, tendon flaps have the
benefits of autologous tissues transfers and present less risks of failure than free flaps. Among them,
Peroneus Brevis flap is easy to perform and leads to donor site’s low morbidity. Our preliminary
experience provides support for this technique to be potentially validated in larger more controlled trial.
