The cause of osteochondritis dissecans of the talus is controversial. Some physicians believe it is the result of an injury or trauma to the ankle.Typically, however, a CT scan or an MRI is needed to confirm the diagnosis and evaluate the extent of the problem. 1.1. Osteochondritis dissecans (OCD) is a condition in which a segment of articular cartilage and subchondral bone separatesOther commonly affected sites are the talus (ankle), capitellum of the humerus (elbow), and femoral head (hip).lunate magnetic resonance imaging (MRI) metaphysis. Magnetic Resonance Imaging.Osteochondritis dissecans of the femoral head occurs as a rare complication in the late onset of Legg-Calv-Perthes disease, possibly secondary to a persistent loose fragment or the weakening induced during the revascularization phase.

Ultimately, osteochondritis dissecans is best diagnosed with imaging studies, such as magnetic resonance imaging scan (MRI scan) or an arthrogram. What is the treatment of osteochondritis dissecans? In 16 cases the changes were osteochondritis dissecans, either with sequestra or with multilocular cysts, and in three cases so-called synovial cysts. The site was in 13 cases the upper medial and in five cases the upper lateral angle of the talus, and in one patient both. X-ray and MRI revealed an osteochondritis dissecans lesion at an unusual tibial plateau location (Fig. 6d.4).Surgical treatment of OCD of the talus is controversial, with conflicting results reported in the literature. OCD and traumatic injury to the tarsocrural joint are less forgiving than in other joints. Proximal surface of talus. Head of 1st metatarsal. Most patients are athletic.

Imaging.Most often affected are the femoral condyles, the trochlea tali, and the distal humerus.In MRI, the signal of the fragment may be heterogeneous and may show several small lowsignal- intensity foci corresponding to bony elements. A Patients Guide to Osteochondritis Dissecans of the Talus. Introduction.Special tests such as a computerized tomography (CT) or a magnetic resonance imaging (MRI) scan may be necessary to determine the full extent of the area involved. Osteochondritis dissecans (OCD) is a problem that causes pain and stiffness of the ankle joint.On the talus, this covering is about one-eighth of an inch thick. This material allows the bones of theSpecial tests such as a computerized tomography (CT) or a magnetic resonance imaging (MRI) If the x-rays indicate that there is a bony abnormality in the talus suggestive of an osteochondritis dissecans then an MRI and/or CT scan may be ordered for the purposes of diagnosis and determining a treatment plan. Osteochondritis dissecans occurs in the knee joint in two groups of patients: (1) in. abnormal ossification within the epiphy-sis,12.44o6r8a combination of these.44A few series have shown a genetic predisposi Dipaola, Arthroscopy, 1991.

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.

Osteochondral Lesions of the Talus: Effect of Defect Size and Plantar flexion Angle on Ankle Joint Stresses. 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.

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 has been touted as helping in decision-making. CT scanning is favored by some for talar lesions, MR imaging is more sensitive for bone bruising.6. Berndt GL, Harty M.

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. 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.
