Osteochondral Lesions of the Talus Wheeless

Location: http://www.wheelessonline.com/ortho/osteochondral_lesions_of_the_talus_dup_of_5051

Although a traumatic etiology is believed to play a major role in production of these lesions, idiopathic osteonecrosis may be another factor;
Anterolateral lesions:
- may result from impaction of talus on fibula as the dorsiflexed ankle is forced into inversion (see ankle sprain);
- the vast majority are caused by trauma;
- these...

2000 Posttraumatic subchondral bone contusions and fractures of the talotibial joint

Location: http://www.ajronline.org/cgi/content/full/175/6/1707

OBJECTIVE: The objective of this study was to determine the presence and location of subchondral bone contusions, fractures, and "kissing" lesions of the talotibial joint after a sprain of the ankle shown on MR imaging. MATERIALS AND METHODS: We retrospectively reviewed the images of all consecutive patients who underwent MR...

Extra-articular extrusion of an osteochondral fragment of the talar dome

Location: http://www.jbjs.org.uk/cgi/reprint/85-B/3/431

Osteochondral fractures of the talus are uncommon. They are classified according to Berndt and Harty, as progressing in severity through four stages. This classification, however, does not address extra-articular extrusion of the osteochondral fragment. We report an osteochondral lesion of the talar dome which presented as an extruded extra-articular fragment...

Foot Fractures Frequently Misdiagnosed as Ankle Sprains

Location: http://www.aafp.org/afp/20020901/785.html

Most ankle injuries are straightforward ligamentous injuries. However, the clinical presentation of subtle fractures can be similar to that of ankle sprains, and these fractures are frequently missed on initial examination. Fractures of the talar dome may be medial or lateral, and they are usually the result of inversion injuries,...

Osteochondral lesions of the talar dome

Location: http://www.ncbi.nlm.nih.gov/pubmed/15156819

Osteochondral lesions were first described by Konig in 1888. He theorized that spontaneous necrosis was a causative factor for this condition. In 1922, Kappis described osteochondral lesions in the talus. Rendu,in a report published in 1932 describing intraarticular fractures of the talus, was the first to propose that these lesions may...

The role of bone scintigraphy in the evaluation of talar dome fractures

Location: http://jnm.snmjournals.org/cgi/reprint/32/12/2241

We undertook a retrospective study of 122 patients with ankle pain to determine the accuracy of bone scintigraphy using 99mTc-methylene diphosphonate (MDP) for detection of osteochondral talar dome fractures (OCTDF). Plain radiographs, which were available in 97 patients, had not revealed any abnormality in the talar dome. Bone scintigraphy was...
