Diagnosis. 2016 Jun; 10(6):22-29 Radiology: Intra -articular osteoid osteoma at the femoral trochlea treated with osteochondral autograft transplantation Leeman et al. 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. The staging, prognosis, and treatment of osteochondral lesions in the elbow are based on a combination of radiographic, magnetic resonance imaging, and arthroscopic findings. Background: Osteochondral defects represent a main risk factor for osteoarthritis of the ankle. Prominent anterior talar neck spur noted. 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. 3-2). 11 Chondral injuries generally occur to either the anterolateral or posteromedial ankle.
