The diagnosis and investigation of such lesions have been greatly enhanced by modern high resolution magnetic resonance imaging capabilities, which have provided far greater detail of the pathological anatomy. Osteochondral lesion of the talus (OLT) is a relatively com-mon injury that causes pain in the ankle in recreational and professional athletes. The top of the talus is dome-shaped and is completely covered with cartilage—a tough, rubbery tissue that enables the ankle to move smoothly. Sign in using your membership username and password. (b) The sagittal MRI shows a thin fibrillated cartilage covering the osteochondral lesion in the medial aspect of the talar dome. 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 cause of osteochondral lesions is also discussed. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. The blood supply to the talus is not as rich as many other bones in the body, and as a result injuries to the talus sometimes are more difficult to heal than similar injuries in other bones.

Osteochondral lesions of the talus in a sports medicine clinic. The Gustilo Anderson classification, also known as the Gustilo classification, is the most widely accepted classification system of open (or compound) fractures. An osteochondral lesion of the talar dome is a condition characterized by damage to the cartilage and / or bone surfaces of the upper (superior) aspect of the talus bone (i.e. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. grade 2: wound 1-10 cm in length without extensive soft-tissue damage, flaps or avulsions. Lateral osteochondral lesions are usually located in the anterior third of the talar dome. A classification system applicable to both MRI and arthroscopy is proposed. Loomer, R. , Fisher, C. , Lloyd-Smith, R. , Sisler, J., Cooney, T.: . Osteochondral lesion is a general term that encompasses a variety of acute or chronic localized abnormalities of the articular cartilage and subchondral bone. location of OCLs, respectively.5,8–11 These classifications have typically been used to characterize OCLs of the talus (OCLT), describing the degree of osteochondral involve-ment and the location of the lesion.5,8–11 In 1959, Berndt and Harty described a classification system for OCLs on plain radiograph, which Anderson referenced to create Ankle sprains are a common cause of OLTs.

Find out about Lean Library here, If you have access to journal via a society or associations, read the instructions below. 8 Table 1. Classification of osteochondral lesions of the talus using MRI. Stage 2 - partially detached fragment. Stage IIA: Cystic lesion with communication to the talar dome surface. We instructed her to take a period of rest from participating in sports, including basketball, and surgery was put off at this time. From this case-series study was derived the Berndt and Harty classification which is considered to be the standard classification for this type of injuries and which is based on plain radiographs and surgical exploration. The talus is the bottom bone of the ankle joint. According to the modified Neer classification, the lesion had 'healed' radiologically. Stages I and II are stable lesions. Severe locking or catching symptoms, where the ankle freezes up and will not bend, may indicate that there is a large osteochondral lesion or even a loose piece of cartilage or free bone within the joint. Last, a commonly used arthroscopic classification is the OCL classification of the International Cartilage Repair Society. Osteochondral defect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5.It is often used synonymously with osteochondral injury/defect and in the pediatric population.

However, both stagings represent the pathological conditions associated with OCD's natural progression. Results: Of the 43 patients, 21 (48.8%) presented with osteochondral lesions on MRI. Magnetic resonance imaging (MRI) showed a high intensity area at the medial talar dome on T2 weighted images, the OLT was classified as grade 3 according to Anderson's classification . Purpose: The purpose of this study was to show that magnetic resonance imaging (MRI) can accurately and noninvasively evaluate the articular cartilage overlying osteochondral lesions of the talus, using arthroscopy as the standard, and provide information about lesion stability. This term refers to a wide spectrum of pathologies including mild bone marrow contusion as well as severe osteoarthritis resulting from long standing disease. †Department of Orthopaedics, Avon Orthopaedic Centre, Southmead Hospital, Bristol, United Kingdom. Stage 4 - displaced fragment. The MRI classification of osteochondral lesions of the talus developed by Anderson et al 7 defines stage 1 as bone marrow edema. The earliest report of osteochondritis dissecans (OCD) was published in 1888 by Konig, who characterized a loose-body formation associated with articular cartilage and subchondral bone fracture. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). Figure 7: Stage 1 lesion according to Anderson classification. Articular Cartilage Defects of the Ankle JORDAN KERKER RICHARD D.
