(A) Preoperative anteroposterior and lateral radiographs of the ankle. Operative indications are chronic pain at the distal part of the fibula, symptoms of instability at the anterior talofibular ligament and/or calcaneofibular ligament, and a radiographic finding of an os fibulare. Careers. Os subfibulare can be especially debilitating for children and adolescents when symptomatic [4-7]. When the os subtibiale is associated with a ligamentous injury, conservative treatment is usually adequate. Os subfibulare was originally described by Leimbach [] in 1937 and is defined as an ossicle around the tip of the lateral malleolus of the ankle joint.Two main etiologies of the os subfibulare are discussed in the literature, including (1) accessory ossification center [22, 31, 34, 51, 52] and (2) posttraumatic sequelae of an avulsion fracture of the distal fibula following an ankle injury [38 .

We analyzed 36 patients complaining of functional instability without laxity, 1 year after an ankle inversion trauma associated with the observation of a subfibular ossicle. Note that displacement on varus stress testing was not a consistent finding in our series. The larger size and talofibular impingement of the ossicle were associated with greater need for operative treatment in patients with ankle instability. Conclusions: Os subfibulare is an anatomic variant considered either as a failure of an accessory ossification center to unite to the distal fibula, or, a supernumerary bone at the apex of the fibula [21, 22].
