the talar dome) in the ankle. OCD lesions of the elbow are typically found in athletes in the teen years after the physis has closed. The dome of the talus is covered by the trochlear articular surface, which supports the weight of the body. Lateral lesions are located in the middle third of the talar dome and are shallow and wafer- shaped. 1. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). The medial lesions tend to be deeper and cup shaped whereas the lateral lesions tend to be thinner and more wafer shaped . It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). The medial and lateral articular facets of the talus articulate with the medial and lateral malleoli. Symptoms of Osteochondral Lesion of the Talus. An osteochondral lesion of the talar dome is a condition characterized by damage to the cartilage and / or bone surfaces of the upper (superior) aspect of the talus bone (i.e. Symptoms of osteochondral lesions of the talus tend to develop gradually, and … “Osteo” means bone and “chondral” refers to cartilage. The treatment options are numerous and constantly evolving, with no well-established evidence base to … Osteochondral lesions of the talar dome are relatively common causes of ankle pain and disability. On the basis of repetitive microtraumas, avascular … This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). There are differing degrees of severity varying from very small undisplaced lesions to those that create large loose bodies and develop cysts in the talus. Osteochondral lesions of the talus, or talar dome lesions, can be classified as ischaemic or traumatic injuries and can be debilitating if untreated. The talar dome is trapezoidal in shape, and its anterior surface is, on average, 2.5 mm wider than the posterior surface. Talar dome lesions … If left untreated, osteochondral lesions of the talar dome can develop into arthritis. Medial lesions are typically located in the posterior third of the talar dome and are deeper and cup shaped (2). Osteochondral lesions of the talus are an increasingly recognised pathology of the ankle joint and can lead to significant complications if not treated appropriately. “Osteo” means bone and “chondral” refers to cartilage. Hereby, the most common reasons are a severe inversion ankle sprain, chronic ankle instability (CAI; causing in 5–9% of the cases a lateral talar OCL), 9, 10 or a fracture mechanism. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. One of the best diagnostic tests of an ankle osteochondral lesion of the talus is a diagnostic anesthetic injection of the ankle joint. Please note that OCD is a commonly used abbreviation for both osteochondral defect and osteochondritis dissecans, two closely related conditions. Treatment for osteochondral lesions of the talar dome vary depending on the severity of the injury. It is often associated with a traumatic injury, such as a severe ankle sprain. It is currently accepted that OCL of the talus is primarily traumatic in origin. Treatment depends on the severity of the talar dome lesion. Talar dome injuries result from trauma to the ankle including ankle sprains (6-38% of all ankle sprains), fractures (greater than 70% of all ankle fractures). “Osteo” means bone and “chondral” refers to cartilage. An osteochondral lesion of the talus (OLT) is an area of abnormal, damaged cartilage and bone on the top of the talus bone (the lower bone of the ankle joint). Figure 1 Relevant Anatomy for an Osteochondral Lesion of the Talar Dome A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. non-surgical treatment fails to relieve the symptoms of talar dome “Osteo” means bone and “chondral” refers to cartilage. OCD usually causes pain during and after sports. The most common sites are the posteromedial (53%) ( Fig. Approximately 50% of ankle sprains and up to 73% of ankle fractures result in some level of cartilage injury, and there are over 2 million ankle sprains alone per year.
