For those ossicles located anteromedially to the lateral malleolus and not at its tip, the interface between the ossicle and lateral malleolus is oblique. Arthroscopic synovectomy of the lateral gutter of the ankle joint is performed with an arthroscopic shaver (Dyonics; Smith & Nephew, Andover, MA) (Fig 3). Subtalar instability, if present, cannot be detected during ankle arthroscopy. Avulsion fracture of the lateral ankle ligaments in cases of severe inversion injury is more common than previously believed and requires high level of suspicion in order to obtain an accurate diagnosis and achieve adequate stability.

Two cases of os subfibulare were treated by a different surgeon at our institution with debridement and screw fixation. Acute trauma or chronic inversion stress can lead to avulsion of the ossicle from the lateral malleolus, and the ankle may become symptomatic.2 Both size and location of the os subfibulare play a role in determining the clinical effect of the separated ossicle. Data is temporarily unavailable. It is a round or comma-shaped bone which is rarely seen (Figure 7 ). After removal of the os subfibulare, the fibular bed is debrided to healthy cancellous bone. Falling on an outstretched hand. 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. 2 The ossicle is sometimes symptomatic and presents with local pain or lateral ankle instability. A 2.7-mm 30 arthroscope (Henke Sass Wolf, Tuttlingen, Germany) is used for this procedure. Avulsion fracture may fail to unite because it is intra-articular and bathed in synovial fluid or because the tension on the anterior talofibular ligament attached to the ossicle causes a separation of the fragment from the bone. Perform an approach to the lateral malleolus and excise the fragment while preserving the anterior talofibular ligament and calcaneofibular ligament. The site is secure. [Clinical outcome of arthroscopic excision of the os subfibulare in ankle pain]. The patient is in supine position. Displacement of the os subfibulare can be shown during an inversion stress test (Fig 1). Accessibility government site.

Avoid making bone tunnels through the distal fibular physis in skeletally immature patients. Buckled Fracture: (or impacted fracture), ends are driven into each other; commonly seen in arm fractures in children. The knee is flexed and supported by a triangular supporting frame (Innomed, Savannah, GA) during the arthroscopic procedure. Pass one of the calcaneofibular ligament stitch ends through the middle tunnel (with the one anterior talofibular ligament stitch), and pass the other calcaneofibular ligament stitch end through the most distal hole (Fig. It is usually detected incidently, however, it may be misdiagnosed as lateral malleolar avulsion. Incidence and Significance, Symptomatic ossicles of the lateral malleolus in children, The symptomatic os subfibulare. Recurrent lateral ankle sprains and instability during athletic activity. The opposing surfaces of lateral malleolus and os subfibulare are debrided with an arthroscopic shaver.

OS, os subfibulare. This report describes the technical details of arthroscopic stabilization of the unstable os subfibulare. FOIA One theory proposes that it is caused by an avulsion fracture attributable to pull of the anterior talofibular ligament, whereas the other theory proposes that it is the result of an accessory ossification center. Also, no author has had any other relationships, or has engaged in any other activities, that could be perceived to influence or have the potential to influence what is written in this work. The stability of the ossicle and lateral ankle is evaluated. J Foot Ankle Surg. Arthroscopic stabilization of unstable os subfibulare has the advantages of better cosmetic results, less pain, and less surgical trauma. An ossicle that is >10mm or located at the anterior distal end of the lateral malleolus is more likely to be associated with disruption of the lateral ankle ligament complex.3, In general, nonoperative treatment (a period of rest with restricted weightbearing or immobilization) should be the first line of treatment.1 Surgical treatment is indicated if conservative treatment fails to relieve symptoms. While three patients returned within the first three days for splitting of a tight cast, there were no wound complications, compartment syndromes, or infections. The stability of the os subfibulare after screw fixation is tested. 2 Berg 1stated that separated ossicles of the lateral malleolus are an avulsion fracture rather than a normal variant. At the time of surgery, every bone fragment in our series was attached, either completely or to a portion of either the anterior talofibular ligament or the calcaneofibular ligament. 1 it is a result of an unfused accessory ossification center or an avulsion fracture of the anterior talofibular ligament.

Avulsion fracture of the fibula associated with recurrent instability of the ankle. The site is secure. The incidence of os subfibulare at the initial radiograph was about 1%. There are three common accessory ossicles in the ankle: os trigunum (usually forms at 7-13 years old); os subtibiale (when the medial malleolus epiphysis fails to fuse with the tibia in the later teenage years); os subfibulare (can also be an unfused ossification centre or an avulsion fracture). Indications and Contraindications of Arthroscopic Stabilization of Unstable Os Subfibulare. Relation of severity and disability. Microfracture of the fusion surface of the os subfibulare is not effective because of the mobility of the ossicle.
