Pitfall
Be cautious while deepening the fibular groove with respect to the ligamentous structures. Medially from the groove, the posterior syndesmotic ligaments and the posterior talofibular ligament are located. Follow the contour of the groove from proximal to distal. The calcaneofibular ligament inserts more anterior in the most distal part of the lateral malleolus. When shaving the groove distally and anteriorly, aim the shaver medial from the calcaneofibular ligament insertion
