In 7 patients with OCD of the humeral head (all males ranging in age from 12 to 44 year), 5 of the patients (71%) demonstrated lesions in the right shoulder, suggesting an association with right-handedness. Kijowski R, De Smet AA. The incidence of osteochondritis dissecans in the condyles of the femur. Clin Sports Med. This retrospective study on OCD reporting and classification highlights the inadequacy of existing classification schemes, and emphasizes the critical need for improved diagnostic MRI protocols in musculoskeletal radiology in order to propel it toward evidence-based medicine.

See the main osteochondritis dissecans … Lateral radiograph of the knee reveals a calcified loose body (white arrowhead) in the infrapatellar fat pad and lucency in the articular surface of the patella (black arrowhead). Osteochondritis dissecans (OCD) can affect both adults and children, however the imaging characteristics and significance of imaging findings can differ in the juvenile subset with open physes. New Orleans, LA. Gregersen HE, Rasmussen OS. Case Discussion. 94 (14):1322-4. The purpose of this study was to investigate the performance of MRI criteria for predicting instability of osteochondritis dissecans (OCD) lesions of the elbow in children. [Medline]. Adv Orthop. [Medline]. [Medline]. Int Orthop. [13]. CT scans can be used to assess the osseous integration after refixation of OCD loose fragments. Posterior longitudinal sonogram reveals an unstable lesion with a slightly displaced fragment (asterisk) and a wide gap formation (arrows; courtesy of Dr Masatoshi Takahara). 2005 May. [Medline]. As the process progresses, more pronounced contour abnormalities, fragmentation and density changes (both lucency and sclerosis) become evident.
