Osteochondral defects (OCD) or lesions (OCL) are focal areas of damage with articular cartilage damage and injury of the adjacent subchondral bone plate and subchondral cancellous bone. Osteochondritis dissecans (OCD) OCD represents a chronic “overload” injury of the epiphysis. Etiology relates to a subchondral fatigue fracture usually as a result of shearing, rotatory or tangentially aligned impaction forces. Osteochondral lesions (osteochondritis dissecans) of the talus are common articular lesions that are usually traumatic in origin. Osteochondritis dissecans (OCD) of the elbow is a con-dition of the subchondral bone and overlying cartilage, ... Grading of all OCD lesions is presented in Table 3. There is a small amount of signal within the underlying bone without any cyst formation or bone loss The patient had… She has no history of acute injury, and she reported no episodes of instability, giving-way, or locking of the knee.

Osteochondritis Dissecans: Etiology, Pathology, and Imaging with a Special Focus on the Knee Joint. Osteochondritis dissecans (OCD) of the elbow is a condition of the subchondral bone and overlying cartilage, mostly affecting a part of the humeral capitellum. Osteochondritis dissecans (OCD) of the elbow is localised most commonly at the capitellum. Osteochondritis Dissecans. Nowadays, the term of Osteochondritis Dissecans (OCD) is the most widely used for an idiopathic fracture line extending through the articular cartilage and the underlying bone in the knee [1, 2]. With the advent of MRI, this grading system was further revised including evaluation of structures invisible on conventional radiology, such as the integrity of the cartilage and presence of BME. In children whose bones are still growing, the bone defect may heal with a period of rest and protection. Mesgarzadeh M, Sapega AA, Bonakdarpour A, et al. Lower: oblique view.

Diduch DEFINITION Osteochondritis dissecans (OCD), avascular necrosis (AVN), spontaneous osteonecrosis of the knee, and chondral and osteochondral lesions all occur at or beneath the articular surface of a weight-bearing joint and are easily confused (FIG 1). MR grading system of osteochondritis dissecans lesions: Comparison with arthroscopy European Journal of Radiology, Vol. It can also affect other joints, such as elbows and ankles. The capitellum of the immature elbow has a tenuous vascular supply consisting of one or two posterior vessels. This condition occurs when a piece of the bone partially or fully separates from the end of the bone that forms a joint. 1 .
