The clinical diagnosis was a biceps tendinitis or a bicipital bursitis. Unable to process the form. Although there is ongoing debate regarding the pathogenesis of OCD, there is a consensus supporting a traumatic/mechanical theory of injury to the osteochondral unit. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. (A) T1-weighted and (B) fat-saturated T2-weighted sagittal imaging of the ankle show an osteochondral lesion in the proximal cuboid in a patient who has refractory lateral ankle pain, failing conservative therapy after a severe sprain. The mechanism of injury leading to osteochondral injury in the hip is as yet uncer-tain; however, we propose two possible theo-ries. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Imaging Studies. Particularly in the younger patient, MRI plays an important clinical role in the diagnosis of pre-radiographic OA and focal osteochondral injury. The location of the abnormality is dictated by the mechanism of injury. Materials and methods: Patients with trochlear abnormalities were identified through keyword search of radiology dictations from 1999 to 2007. Publicationdate 2019-03-01. We also have observed several patients with osteochondral injuries of the lateral femoral condyle after transient dislocation of the pa-tella. 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. Swelling and pain to lateral malleolus. Article Rating. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Symptoms will vary depending on the type, extent and chronicity of the cartilage injury and include swelling, pain and decreased range of motion of the affected joint as well as stiffness or instability. Developed by renowned radiologists in each specialty, STATdx provides comprehensive decision support you can rely on - Osteochondral Injury, Shoulder Injuries to the talar dome should be suspected when an athlete presents with chronic ankle pain following an injury to the ankle. Subsequent MR imaging shows that there is a 15 mm osteochondral lesion at the lateral capitellum with separation of a bony fragment that is approximately 13 x 11 x 6 mm in depth. PURPOSE: To evaluate the cross-sectional imaging features of osteochondral defects (OCDs) of the glenoid fossa and to elicit a more detailed analysis of the trauma, if any, that may cause this injury. In this case, the lesion was caused by avascular necrosis of the bone just under the cartilage. Although an association with mechanical and traumatic factors has been established, the etiology remains poorly understood. Trauma. More recently, there has been brief mention in both the radiology and orthopedic literature of osteochondral injuries involving not only the patellar articular surface but also the articular surface of the lateral femoral condyle [6-10]. Materials and methods: Eight patients (seven male patients, one female patient; age range, 15-42 years; mean age, 27 years) with an OCD in the glenoid fossa were identified. Areas of decreased density (i.e., darker areas) seen on the plain x-rays (Figure 2) can be indicative of this condition, although it is not uncommon for the plain x-rays to be read as normal. Top Magn Reson Imaging 1998; 9:348-359. Soft tissue swelling adjacent to the lateral malleolus. Shoulder and Humerus. This is an unstable lesion with level of instability related to extent of cartilage fracture 5. Although osteochondral lesion is not a new diagnosis, our recognition of femoral head osteochondral lesions on MR imaging is likely reflective of the fact that MR imaging is now performed more frequently in patients with a symptomatic hip and normal radiographic findings. No acute fracture identified. 3-2). Griffith,D.T. 20, No. ...

ADVERTISEMENT: Supporters see fewer/no ads. Objectives: The aim of this article is to provide an overview of current optimal clinical cartilage imaging techniques of the foot and ankle and to show typical osteochondral injuries on imaging. 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 are acquired, potentially reversible injuries of the subchondral bone with or without associated articular cartilage involvement. Osteochondral lesions of the elbow are injuries that disrupt the cartilage and subjacent bone, and they most commonly involve the capitellum. Intra-articular osteochondral fracture of the talar dome as described. These imaging modalities each have pros and cons for evaluation of osteochondral lesions. Articular cartilage injuries of the knee can be debilitating if not treated properly. Frequently, acute injuries are not initially detected, and are thus managed as chronic lesions. The patient's medical record, imaging studies, and surgical reports were reviewed. acute–subacute injuries that predispose such individuals to early degenerative changes of the hips. Well defined small lucencies in the lateral aspect of the distal fibula and deformity of the distal fibula are consistent with previous internal fixation of an old fracture. The ankle mortice is overall maintained. Rubin DA, Kettering JM, Towers JD, Britton CA: MR imaging of knees having isolated and combined ligament injuries. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. It is a general term used to characterize the pathology encountered at the joint surface with no consideration of etiology. If radiographs are negative but an osteochondral lesion is still suspected, advanced imaging with MRI or CT scan is indicated. Osseous Pathology. We describe the clinical and radiographic features of 11 athletes found to have femoral head lesions similar in MR imaging appearance to osteochondral lesions in … Plain x-rays can be used to help diagnose an osteochondral lesion.
