  1. Osteochondritis dissecans of the talus is a subset of osteochondral lesions of the talus that also includes osteochondral fractures, avascular necrosis, and degenerative arthritis. Osteochondral lesions of the talus can be associated with injury to the ankle
  2. Osteochondritis dissecans (os-tee-o-kon-DRY-tis DIS-uh-kanz) is a joint condition in which bone underneath the cartilage of a joint dies due to lack of blood flow. This bone and cartilage can then break loose, causing pain and possibly hindering joint motion. Osteochondritis dissecans occurs most often in children and adolescents
  3. Osteochondritis dissecans can often be a progressive pathologic process: evolving to joint deformity and occasionally bone and cartilage fragmentation to intra-articular cartilage instability. When osteochondritis dissecans affects the ankle it typically occurs on the inner or medial portion of the ankle (talus)
  4. An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL)
  5. Osteochondritis dissecans (OCD) is a problem that causes pain and stiffness of the ankle joint. It can occur in all age groups. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. This guide will help you understan

Osteochondritis Dissecans of the Talus. Osteochondritis dissecans can cause pain and stiffness of the ankle joint. These lesions are thought to be caused by injury to the bone underneath the joint surface or by loss of blood supply to a part of the bone. There may be intermittent swelling, pain in the joint. X-rays of the ankle usually reveal a. Osteochondritis dissecans (OCD) is a condition that develops in joints, most often in children and adolescents. It occurs when a small segment of bone begins to separate from its surrounding region due to a lack of blood supply. As a result, the small piece of bone and the cartilage covering it begin to crack and loosen Osteochondritis dissecans (OCD) is the end result of the aseptic separation of an osteochondral fragment with the gradual fragmentation of the articular surface and results in an osteochondral defect. It is often associated with intraarticular loose bodies Osteochondritis dissecans (OCD) of the ankle is the end result of the aseptic separation of an osteochondral fragment of the talar dome with the gradual fragmentation of the articular surface. See the main osteochondritis dissecans article for a general discussion on this condition, which mostly affects the knees Osteochondral injuries of the talus are either idiopathic (osteochondritis dissecans) or related to a traumatic event (ankle sprain or fracture). Tol et al. 1, in a review of >580 osteochondral defects of the talus, reported that trauma was implicated as the cause in 76% of the cases

Abstract Osteochondritis dissecans (OCD) of the talus is rare in children. The lesion is encountered on either the medial or lateral surface of the talar dome. The etiology is unknown, although trauma has been implicated, particularly in lateral lesions Osteochondral lesions, also known as osteochondritis dissecans, are areas of damaged bone and cartilage on the surface of the ankle bone (the talus), usually caused by an ankle injury An osteochondral ankle defect is a lesion of the talar cartilage and subchondral bone mostly caused by a single or multiple traumatic events, leading to partial or complete detachment of the fragment. The defects cause deep ankle pain associated with weightbearing Osteochondritis dissecans of the talus is defined as a subchondral bony lesion of a small fragment of bone, usually less than 2 cm in diameter, with overlying intact articular cartilage. This fragment then becomes separated from its bed and undergoes necrosis Osteochondritis dissecans is a condition that causes ankle pain and stiffness. Osteochondritis dissecans can affect all age groups and usually follows a twisting injury to the ankle such as an ankle sprain

Conditions and Treatments

Osteochondral lesions are a type of fracture on the surface of the ankle bone (talus). OCD lesions are also called osteochondritis dissecans or osteochondral fractures. Osteochondral lesions are most common in the knee joint, and the ankle is the next most frequent joint affected Description OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. The most common sites are the posteromedial (53%) (Fig. 1) and anterolateral (46%) talar dome (1) Appropriate Use Criteria on the Diagnosis and Treatment of Osteochondritis Dissecans. Appropriate use criteria (AUC) provide treatment recommendations on a patient-specific level using evidence from AAOS clinical practice guidelines, along with clinician expertise and experience BACKGROUND: The ideal treatment for juvenile osteochondritis dissecans of the talus (ODT) is still unclear. To determine predictors of failure of conservative treatment, children admitted for ODT were retrospectively analyzed. METHODS: Patient files were analyzed to search for children treated for an ODT between 2000 and 2011

Osteochondritis dissecans affecting the talus is considered a rare condition. According to Berndt & Harty (1959) it was first reported by Kappis (1922). Without knowledge of Kappis' publication, Wolff (1926), in Denmark, reported two cases, one of which had been diagnosed as early as 1916 Summary. Ankle arthroscopy is an effective procedure for the evaluation and management of osteochondritis dissecans of the talus. For active individuals with detached lesions, excision, curettage, and drilling are an effective treatment. The ability to drill arthroscopically significantly reduces the morbidity associated with open procedures

Osteochondritis Dissecans (OCD) Talus/Tibia The ankle joint is composed of the bottom of the tibia (shin) bone and the top of the talus (ankle) bone. The top of the talus is dome-shaped and is completely covered with cartilage (connective tissue that allows the ankle to move smoothly) Most often, our experts use cartilage regeneration to repair osteochondral lesions of the talus, also known as osteochondritis dissecans. The talus is the bone at the bottom of your ankle joint. Osteochondral lesions happen when you injure the talus and its cartilage. Normally, the pain from a sprain or other injury goes away with treatment Osteochondritis Dissecans of the Talus - OATs Post Op. Posted by momamiya @momamiya, Jun 15 12:42am. Hi!
