Causes. Anderson, I.A. Consequently, fractures described as osteochondral must be sought within the fragmentary fractures. OCD is classified by the progression of the disease in stages. It has been reported that the incidence of delayed or misdiagnosis in patients with unexplained chronic ankle pain as high as 81%. The severity of the osteochondral lesions was assessed according to the Anderson classification. 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. (b) The sagittal MRI shows a thin fibrillated cartilage covering the osteochondral lesion in the medial aspect of the talar dome. The location and containment of the osteochondral lesion of the talus also may be implicated in the prognosis following the use of bone-marrow-stimulation techniques. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. This product could help you, Accessing resources off campus can be a challenge. Fluid extended deep to the fragment, and there was subjacent marrow edema, all seen in Fig. 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.

[] In 1922, Kappis described this process in the ankle joint. Resnick, D. , Niwayama, G., Coutts, R.D. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. Gustilo-Anderson classification. This chapter is adapted from Chao W, Freeland E, Dedini R: Osteochondral Lesions of the Talus in … They require a strong plan. A 16 × 19 mm osteochondral lesion was noted in the superior aspect of the lateral trochlea. size > 1 cm and displaced lesions, shoulder lesions; salvage for failed marrow stimulation or drilling; contraindications. Recent findings: Recent research has included larger cohort studies with longer follow-up as well as quality systematic reviews and meta-analyses. While the arthroscopic classification of osteochondral lesions is considered standard, the Anderson MRI staging is the main form of staging used in this article. Stage 2A represents a subchondral cyst; stage 2B, an incomplete separation of the osteochondral fragment; stage 3, fluid around an undetached, nondisplaced osteochondral fragment; and stage 4, a displaced osteochondral fragment of the talus. 8 Table 1.

Stone MD Key Points Although osteochondral lesions can occur over any portion of the talar dome or the tibia, the talar lesions typically occur over the anterolateral or the posteromedial talar dome. 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). Access to society journal content varies across our titles. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. There was a fragmented and sclerotic fragment overlying the osteochondral lesion. They were thoroughly described 15 years ago in a round table session organized by Doré and Rosset for the Société orthopédique de l’Ouest. Zalavras CG, Marcus RE, Levin LS et-al.

Find out about Lean Library here, If you have access to journal via a society or associations, read the instructions below. 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. Stage 3 - detached but undisplaced fragment. For more information view the SAGE Journals Article Sharing page. 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. Stages I and II are stable lesions. Management of open fractures and subsequent complications. Stage 2 - partially detached fragment. Lean Library can solve it. 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. Lateral osteochondral lesions are usually located in the anterior third of the talar dome. a Grade 2a osteochondral lesion medial central aspect of talar dome. Purpose of the review: To review the most recent literature on osteochondritis dissecans (OCD) lesions of the capitellum in overhead athletes and describe a treatment algorithm based on current best evidence and surgeon experience. 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 . A lateral lesion has a typical shallow and wafer shape, indicating a shear mechanism of injury. Osteochondral fractures of the dome of the talus. There are two main staging classifications used; one is determined by MRI diagnostic imaging while the other is determined arthroscopically. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease.

FIGURE 3 Ferkel and Sgaglione’s CT classification of osteochondral lesions of the talus. According to the modified Neer classification, the lesion had 'healed' radiologically. CT is the most precise means of evaluating the bone lesion itself. MRI correctly identified all 40 osteochondral lesions and all 14 normal ankles. 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. Isolated lesions of cartilage or subchondral bone are not considered an OCD 6.. Members of _ can log in with their society credentials below. Stage 4 - displaced fragment. The cause of osteochondral lesions is also discussed. Ankle sprains are a common cause of OLTs.
