Radiology department of the Amsterdam University Medical Centre in Amsterdam and Alrijne hospital in Leiderdorp in the Netherlands. She had no history of trauma. In case of osteochondral fracture/injury, it is sometimes hard to tell if the fractured fragment is stable or not. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. Griffith,D.T. 0 0 vote. In the presented case the fragment was frankly displaced, making it without doubt stage IV osteochondral injury. If you would see this in the capitellum you would call it an osteochondral lesion of the capitellum. Two much smaller interarticular bony fragments. 11 Chondral injuries generally occur to either the anterolateral or posteromedial ankle. The combined use of standard and newer magnetic resonance (MR) imaging techniques makes it possible to evaluate both the morphologic status and the biochemical contents of the repair tissue (,1–,9).

Shoulder and Humerus. This is an unstable lesion with level of instability related to extent of cartilage fracture 5. This type of injury can be due to a severe ankle sprain that causes bone and cartilage to become loose, resulting in ongoing ankle pain. Osteochondral Injury – Coronal T2 weight MRI with fat saturation confirms a large osteochondral injury at the lateral talar dome (yellow arrow) with marked surrounding bone edema characterized by high T2 signal. Osteochondral injury. An inversion injury to the ankle with the foot in plantar flexion and lateral rotation of the tibia on the talus lead to a posteromedial talar dome lesion ( , 47 , , 48 ). When occurring in the elbow, osteochondritis dissecans refers primarily to lesions of the anterior aspect of the capitellum, although lesions of the trochlea, radial head, olecranon, and olecranon fossa have been described1. Fractures involving the articulating surfaces of bone are a common cause of chronic disability after joint injury. Elias DA, White LM, Fithian DC. 9 X 9 (axial) X 3 mm osteochondral fragment is demonstrated at the lateral aspect of the talar dome consistent with an intra-articular fracture. An x-ray series of the elbow demonstrates an effusion appears and a relatively large lucent area within the capitellum. Rubin DA, Kettering JM, Towers JD, Britton CA: MR imaging of knees having isolated and combined ligament injuries. This is essential in determining management. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Osteochondral Injury, Knee 1. Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. Osteochondral lesions are acquired, potentially reversible injuries of the subchondral bone with or without associated articular cartilage involvement. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Osteochondral fractures involve are an articular surface injury involving the articular cartilage and the subchondral bone plate. He has had mild intermittent discomfort in his knee for some time, but over the last month or so has developed recurrent locking. There was no recent injury. 1 . Acute Osteochondral Fractures in the Lower Extremities - Approach to Identification and Treatment. Osteochondral Lesion “Osteochondral lesion” is a broad and nonspecific term that has been used to refer to any lesion that involves the articular sur-face and subchondral region of a joint, af-fecting cartilage, bone, or both. 2. An osteochondral injury is an injury to the smooth surface on the end of bones, called articular cartilage (chondro), and the bone (osteo) underneath it. Osteochondral lesions of the elbow are injuries that disrupt the cartilage and subjacent bone, and they most commonly involve the capitellum. These imaging modalities each have pros and cons for evaluation of osteochondral lesions. MRI is the modality of choice, with high sensitivity and specificity for the detection of separation of the osteochondral fragment (see: osteochondral injury staging and osteochondritis dissecans surgical staging). Bookmarks (0) Musculoskeletal. Soft tissue swelling adjacent to the lateral malleolus. Imaging Studies. Osteochondral Injury – Coronal T2 weight MRI with fat saturation confirms a large osteochondral injury at the lateral talar dome (yellow arrow) with marked surrounding bone edema characterized by high T2 signal. Pioneer in Rad Blogging. The clinical diagnosis was a biceps tendinitis or a bicipital bursitis. The overlying cartilage appears intact. Epub 2015 Oct 23. the radiology and orthopedic literature of os-teochondral injuries involving not only the patellar articular surface but also the articular surface of the latera l femoral condyle [6–10]. rts * ABSTRACT CASE Radiographs of the right knee did not show any abnormality (Fig 1). 33, No. Injury results in delamination and potential sequestration of the affected bone. In this study, we aimed to precisely localize the hyperintense signal that is generated at the osteochondral junction when using ultrashort echo time magnetic resonance imaging (MRI) and to investigate the osteochondral junction using sweep imaging with Fourier transformation (SWIFT) MRI.
