Look for loose bodies and damage to the lateral aspect of the talus, which may require debridement. 2. Os trigonum. He reported that an ossicle of the lateral malleolus may be an avulsion fracture from the fibular tip or talus or accessory bones developing from a secondary ossification center. occurs as a plantar medial enlargement of the navicular bone exists as accessory bone or as completely ossified extension of the navicular Genetics inheritance pattern autosomal dominant Associated conditions flat feet posterior tibial tendon insufficiency Anatomy Osteology navicular bone normally has a single center of ossification We hypothesized that os subfibulare could interrupt the talofibular space causing impingement, resulting in chronic pain and functional instability around the lateral malleolus. The pathologic examination showed that the ossicle was covered with fibrocartilaginous tissue. The ossicle itself may fracture. However, there is only one report 2 of os subfibulare being caused by accessory ossification. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Jones J, Yap J, El-Feky M, et al.

The purpose of this Technical Note is to describe the details of arthroscopic stabilization of the os subfibulare. The first is that the ossicles are caused by an avulsion fracture 1,5 and the second is that the ossicles occur as a result of accessory ossification. Summary Osgood-Schlatter disease is osteochondrosis or traction apophysitis of the tibial tubercle, commonly presenting as anterior knee pain in the pediatric population. The anterior talofibular ligament had a low to isointense signal on T2-weighted images; however, the surroundings of the ossicle had an isointense signal on T2-weighted images. Your message has been successfully sent to your colleague. While os subfibulare typically remains asymptomatic, some cases may present with ankle pain or instability. Based on the current patients history and the current findings, the ossicle was caused by an accessory ossification rather than an avulsion fracture of the anterior talofibular ligament.

Pathologic examination showed that the ossicle was covered with fibrocartilaginous tissue, and there was no attachment of ligament fibers at the proximal or the distal ends of the ossicle. As a result, ankle arthroscopy and resection of the ossicle were done. When running, the patient limped and had localized pain over the tip of the lateral malleolus in his right ankle.

Please try after some time. Alignment has been maintained. The ossicle could not be seen directly. All three patients had recurrent ankle sprains and had well-localized and consistent tenderness precisely at the site of the anomalous ossific center. Although asymptomatic, it may become symptomatic occasionally, causing lateral foot pain and requiring surgical excision 2. Richard B. Birrer, Bernard Griesemer, Mary B. Cataletto. 2. Diagnosis can made with pelvis radiographs but frequently require pelvic CT scan for full characterization. It could be dissected easily because the anterior talofibular ligament fibers were not attached to the ossicle directly. (Untersuchungen an 500 Rontgenbildern der Chir Universitatsklinik zu Jena.) The os subfibulare is a normal anatomic variant that represents either an unfused accessory ossification centre or a supernumerary bone [1]. Os subfibulare is a separated ossicle at the tip of the lateral malleolus and inferior portion of the fibular tuberosity of the ankle which is rarely reported. The crutches were discarded after 6 weeks, and the patient returned to athletic activity 4 months after surgery with none of his previous symptoms. The ankle had an effusion, and range of motion was not limited. The anterior talofibular ligament had low to isointense signal images. One day after surgery, the patient was allowed to walk using crutches, but he was not allowed to bear weight for 3 weeks.
