Osteochondritis Dissecans (OCD)Professor Sanjiv Jari23rd February 2016.The current imaging technique of choice is magnetic resonance imaging ( MRI), with high resolution 3T scanners being even more sensitive. Osteochondritis dissecans (OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone. OCD usually causes pain and swelling of the affected joint which catches and locks during movement. Osteochondritis dissecans is an injury to the talus bone of the ankle joint.For that reason, if patients fail to improve, it is often necessary to obtain more sophisticated imaging studies such as MRIs, CT scans, bone scans, or tomograms. MRI magnetic resonance imaging.(OCD osteochondritis dissecans MRI magnetic resonance imaging). Factors such as location of the lesion, relationship to weight-bearing surface, stability, physis closure and clinical presentation should be considered.

An osteochondritis dissecans lesion in the knee is a condition that is caused by a reduction of blood flow to the end of a bone within the knee joint. This condition occurs most often in adolescent males under the age of 25. The first sequence of MRI scans in a coronal scan. OSTEOCHONDRITIS DISSECANS (OCD). What is OCD? Osteochondritis dissecans (OCD) or osteochondrosis is a failure of the bone underlying the smooth articular cartilage inside the joints, i.e. the subchondral bone, to form properly from the skeletons cartilage template.

Imaging The mortis view may show the lesion best. CT and MRI may be helpful to assess the extent of the lesion and cartilage status if operative management is being considered.Stage 4 The fragment becomes a loose body in the joint. Management of Osteochondritis Dissecans. An MRI (magnetic resonance imaging) is also useful in determining the stability or instability of the bone fragment.How is osteochondritis dissecans treated? Once a diagnosis has been made, the treatment goals are to reduce pain, restore the contour of the joint surface and minimize the likelihood This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL).Many patients with talar OLTs are asymptomatic (no pain or swelling). OLTs can be an identifcal finding on an MRI ordered to assess another problem. MRI is the single best study for both the diagnosis and prognosis of the osteochondritis dissecans lesion of the talus. Occasionally other studies may be helpful such as a computed tomography (CT scan) ankle (talus): see osteochondritis dissecans of the ankle.CT has the advantage of sectional imaging through the joint and multiplanar reformats. Findings are similar to those seen on plain film. MRI. There are two main types of osteochondritis dissecans, Adult osteochondritis dissecans and juvenile osteochondritis dissecans.Staging of Osteochondritis Dissecans[4]. Stage. Appearance on MRI. Osteochondritis dissecans of the talus is defined as a subchondral bony lesion of a small fragment of bone, usually less than 2 cm in diameter, with overlying intact articular cartilage.X-ray CT scan or an MRI is commonly used for the diagnosis of the condition. Osteochondritis dissecans (OD) tali is a chronic affection of the subchondral bone and is added to the group of aseptic respective aseptic-idiopatic osteonecrosis.All patients were scored pre- and postoperatively using the Kitaoka score, visual analog pain-scale, native x-ray and MRI. CT scans or MRI (magnetic resonance imagining) may be necessary because often osteochondritis dissecans does not show up on x-rays.Ankle fusion is also used in some cases, if the talus is very badly damaged.
