A Closer Look At The Use Of Interference Screws For Lateral Ankle Stabilization

Erigena Baze, DPM, Danielle N. Butto and Lawrence DiDomenico, DPM

   Perform a stress test. This should demonstrate stability with the talar tilt and anterior drawer tests. After confirming stability, the guide wires exit through the plantar aspect of the foot and one cuts the fiber wire while applying tension on the fiber wire. Then suture the periosteal flap closed at the anterior aspect of the fibula, which includes the transferred tendon acting as another point of fixation. Close the deep and superficial layers per your preference and cast the patient in a neutral position for four weeks. At four weeks, the patient can bear full weight in a surgical cast boot and initiate a physical therapy program.

In Conclusion

Lateral ankle stabilization utilizing an interference screw with a split peroneal brevis tendon transfer is an excellent procedure for anterior talofibular and calcaneofibular ligament repair. The tendon transfer coupled with the tensile strength of the interference screw fixation provides superior stability to the ankle and subtalar joints.
