Abstract

The anatomy of the malleolar peroneal groove is presented. The results are based on a coupled osteological and CTscan study of 20 samples of fibulae. The average distal fibular torsion was 64 degrees. The peroneal groove was oriented posteriorly (mean value: 78 degrees). Three types of morphological variations were found: concave, flat, convex (the convex shaped groove was the most frequent one: 70%). The average width of the groove was 9 mm. These morphometric results were compared to "clinical" ones performed on patients with a peroneal tendons dislocation syndrome: CTscan study showed an osseous dysplasia concerning the groove depth (flat or convex) and/or a torsional insufficiency. Hypothesis of a bone dysplasia in peroneal dislocation syndrome is discussed.
