While the arthroscopic classification of osteochondral lesions is considered standard, the Anderson MRI staging is the main form of staging used in this article. Magnetic resonance imaging (MRI) of the ankle joint. Using MR imaging, in 1989 Anderson and colleagues 7 revised the original classification schema developed by Berndt and Harty, noting that there was no mention of subchondral cyst formation during the evolution of osteochondral lesions, for which stage IIA was added . Using MR imaging, in 1989 Anderson and colleagues 7 revised the original classification schema developed by Berndt and Harty, noting that there was no mention of subchondral cyst formation during the evolution of osteochondral lesions, for which stage IIA was added . Results: Of the 43 patients, 21 (48.8%) presented with osteochondral lesions on MRI. The overlying cartilage is intact at the talus, whereas there is subtle cartilage lesion at the distal tibia (arrow). ‡Department of Radiology, Avon Orthopaedic Centre, Southmead Hospital, Bristol, United Kingdom. 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. Access to society journal content varies across our titles. The radiological results were evaluated using classification described by Hepple et al based on the MRI findings, the location of the lesion, the size of the osteochondral fragment, and the postoperative healing of the lesion. Andersson lesions refer to an inflammatory involvement of the intervertebral discs by spondyloarthritis. Gustilo-Anderson classification. 1989;71A:1143–1152; with permission. Fluid extended deep to the fragment, and there was subjacent marrow edema, all seen in Fig. 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. 4.11a–c. , Graf, B., Lange, R.H.: . grade 2: wound 1-10 cm in length without extensive soft-tissue damage, flaps or avulsions. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. FIGURE 3 Ferkel and Sgaglione’s CT classification of osteochondral lesions of the talus. The severity of the osteochondral lesions was assessed according to the Anderson classification. The Gustilo Anderson classification, also known as the Gustilo classification, is the most widely accepted classification system of open (or compound) fractures. Epidemiologically, the ankle registers 4% of all the human osteochondral defects. Diapaola, J.D. The diagnosis of an osteochondral lesion can be difficult and is often delayed. Osteochondral lesions of the talus (OTL) are among those injuries that we should not fail to recognize, especially following any type of hindfoot injury. Medial lesions are mostly located in the posterior half. MRI correctly identified all 40 osteochondral lesions and all 14 normal ankles. This term covers a wide spectrum of pathologies including (sub)chondral contusion, 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. (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 magnetic resonance imaging (MRI) stages and associated findings (Table 1).8,10 Elias et al.11 originally proposed an Among them, 10 (76.9%) were advanced-stage lesions (stages III and IV according to the Anderson classification). A lateral lesion has a typical shallow and wafer shape, indicating a shear mechanism of injury. Loomer, R. , Fisher, C. , Lloyd-Smith, R. , Sisler, J., Cooney, T.: . Login failed. Stages III and IV describe unstable lesions in which a lesion of the cartilage has allowed synovial fluid between the fragment and bone. 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 . 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). Bosien, W.R. , Staples, O.S., Russell, S.W. Symptomatic osteochondral ankle defects often require surgical treatment. Anderson, I.A. 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. Osteochondral lesion of the talus (OLT) is a common condition associated with ankle injury that brings challenges in the diagnosis and treatment. Much of this bone is covered with cartilage. An Andersson lesion, also known as rheumatic spondylodiskitis, refer to an inflammatory involvement of the intervertebral discs by spondyloarthritis. Osteochondral lesion of the talus (OLT) is a relatively com-mon injury that causes pain in the ankle in recreational and professional athletes.

They were thoroughly described 15 years ago in a round table session organized by Doré and Rosset for the Société orthopédique de l’Ouest. Ankle sprains are a common cause of OLTs. 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.

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. (b) The sagittal MRI shows a thin fibrillated cartilage covering the osteochondral lesion in the medial aspect of the talar dome. For example, Anderson et al. This technique could be a good form of treatment for patients with this condition who have an osteochondral fragment. 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.

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. 2. In their original classification, stage I is a small area of subchondral compression, stage II is a partially detached osteochondral fragment, stage III is a completely detached osteochondral fragment without displacement from the fracture bed, and stage IV is a detached and displaced osteochondral fragment. Soft tissue injury is graded on a combination of: NB: fracture comminution is not considered in the grading system. However, both stagings represent the pathological conditions associated with OCD's natural progression. This chapter is adapted from Chao W, Freeland E, Dedini R: Osteochondral Lesions of the Talus in … There are two main staging classifications used; one is determined by MRI diagnostic imaging while the other is determined arthroscopically.

CT is the most precise means of evaluating the bone lesion itself. There is a certain nosological confusion because many names have been given to these lesions involving both the cartilage and the subchondral bone: osteochondritis, osteonecrosis, osteochondral lesion or fracture, etc. DeSmet, A.A. , Fisher, D.R. Treatment of Osteochondral Lesions of the Talar Dome James W.
