Applied anatomy of peronaeus brevis tendon diverted partly to repair the seperation of tibiofibular syndesmosis

Objective: To provide anatomic basis for peroneus brevis tendon diverted partly to repair the seperation of tibiofibular syndesmosis. Methods: The morphological types of peroneus brevis tendon and the sizes of tibia and fibula were observed and measured on 30 sides of adult lower limb specimens, and two specimens were tested according to the operational need. Result: If we make the site of 1.0cm above ankle joint as standard, the length of peronaeus brevis above it was 12.5 ± 2.2 cm and bellow it was 9.5 ± 1.0 cm. The anteroposterior diameter of fibula was 2.1 ± 0.5 cm; the anteroposterior diameter of tibia was 3.4 ± 0.4 cm; the distance between the anterior margins of tibia and fibula was -2.8±0.4 cm, 1.3 ± 0.3 cm between the posterior margins of tibia and fibula and 5.3 ± 0.4 cm between the medial margin of tibia and lateral margin of fibula. Conlusion: Peroneus brevis tendon diverted partly to repair the separation of tibiofibular syndesmosis is feasible.
