1 ) and anterolateral (46%) talar dome ( 1 ). Symptoms of osteochondral lesions of the talus tend to develop gradually, and … The treatment options are numerous and constantly evolving, with no well-established evidence base to … This presents as a more challenging condition to treat and can often only be addressed by surgical intervention. Also known as a talar dome lesion, this condition causes pain and swelling within the ankle, and left untreated, may lead to long-term damage to the bone. incidence. The medial and lateral articular facets of the talus articulate with the medial and lateral malleoli. Osteochondral lesions of the talus are an increasingly recognised pathology of the ankle joint and can lead to significant complications if not treated appropriately. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. 66 The mechanism for traumatic impaction of the lateral … Osteochondraldefect is a broad term that describes the morphological change of a localized gap in the articular cartilage and subchondral bone 5. 1. In these cases, the most affected area is the posteromedial talar dome (see Table 71-1). On the basis of repetitive microtraumas, avascular … 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. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. There is an association with trauma to the ankle, particularly in lateral talar dome lesions. non-surgical treatment fails to relieve the symptoms of talar dome One of the best diagnostic tests of an ankle osteochondral lesion of the talus is a diagnostic anesthetic injection of the ankle joint. “Osteo” means bone and “chondral” refers to cartilage. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. An osteo-chondral lesion is a defect in the upper surface of the talus that involves bone (osteo) and cartilage (chondral). Appropriate management is therefore vital. Leaving a talar dome injury untreated commonly results in osteoarthritis changes of the ankle joint, chronic pain and limitations in joint range of motion. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Figure 1 Relevant Anatomy for an Osteochondral Lesion of the Talar Dome During this period of immobilization, nonweightbearing range-of-motion exercises may be recommended. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): Although osteochondral lesions can occur over any portion of the talar dome or the tibia, the talar lesions typically occur over the anterolateral or the posteromedial talar dome. Osteochondral lesions of the talus, or talar dome lesions, can be classified as ischaemic or traumatic injuries and can be debilitating if untreated. The most common sites are the posteromedial (53%) ( Fig. “Osteo” means bone and “chondral” refers to cartilage. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. OCD lesions of the elbow are typically found in athletes in the teen years after the physis has closed. Other terms used include an osteochondral defect (OCD), osteochondral lesion of the talus (OLT) and osteochondritis dessecans, which are all used interchangeably. However, medial lesions are more common than lateral OCLs. Methods: A professional rugby league player underwent surgery for a complex injury to the ankle. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). 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). Medial lesions are typically located in the posterior third of the talar dome and are deeper and cup shaped (2). Osteochondral lesions of the talar dome are relatively common causes of ankle pain and disability. Symptoms related to this condition are nonspecific including pain, swelling, stiffness, and mechanical symptoms of locking and catching. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. Osteochondral lesion of the talus (OLT) is a common condition associated with ankle injury that brings challenges in the diagnosis and treatment. “Osteo” means bone and “chondral” refers to cartilage. Talar dome fractures are often missed at the initial examination following an ankle sprain or injury. The treatment given for the sprain or injury usually fails to treat the unidentified fracture. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). “Osteo” means bone and “chondral” refers to cartilage. Background: Talar osteochondral lesions represent challenging clinical entities, particularly in high-demand athletes. focal injuries to the talar dome with variable involvement of the subchondral bone and cartilage resulting in osteochondral lesion of the talus (OLT) may be caused by traumatic event or result of repetitive microtrauma. Please note that OCD is a commonly used abbreviation for both osteochondral defect and osteochondritis dissecans, two closely related conditions. Lateral lesions are located in the middle third of the talar dome and are shallow and wafer- shaped. If the lesion is stable (without loose pieces of cartilage or bone), one or more of the following non-surgical treatment options may be considered: 1. Talar dome lesions usually occur from an injury, such as an ankle sprain. Berndt and Harty proved this in a report in which anteromedial and posterolateral lesions were created using cadavers.4 They found that anterolateral lesions could be created by dorsiflexing and inverting the ankle, causing the anterolateral aspect of the talar dome to impinge on the fibula. Talar dome lesions … This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). It is currently accepted that OCL of the talus is primarily traumatic in origin. Talar dome lesions … OCD usually causes pain during and after sports. This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL). (1,2,3) Talar dome injuries create a focal defect in the dome of the talus that results in injury to the cartilage and underlying bone. The ankle OCD lesion is rare in the pediatric population, mainly occurring in adults with the average age being 21 years of age. Epidemiology. If left untreated, osteochondral lesions of the talar dome can develop into arthritis. Surgical treatment of large lesions often requires a 2-step procedure, or the use of osteotomy in the case of autologous osteochondral transfer, which can delay return to sport. Immobilization – Depending on the type of injury, the leg may be placed in a cast or cast boot to protect the talus. Presentation. 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. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint.
