Magnetic resonance imaging (MRI) is widely used for diagnosing osteochondral lesions in the talus. The purpose of our study was to investigate the performance of MRI findings to predict instability of osteochondral lesion of the talus (OLT) in children and the association between skeletal maturity and lesion stability. The use of MRI enables one to evaluate the tibiotalar joint for synovitis, stress reaction, avascular necrosis, chondritis and osteoarthritis in addition to osteochondral lesions. Introduction. An osteochondral lesion of the distal tibia and fibula has been thought of as a rare condition, although it is located in the same weight-bearing joint as an osteochondral lesion of the talus (OLT). The type of surgery that is required for your osteochondral lesion depends on its size, the age of the patient, the location of the osteochondral lesion, and its characteristics on MRI. (b) The sagittal MRI shows a thin fibrillated cartilage covering the osteochondral lesion in the medial aspect of the talar dome. FIGURE 71-1 Osteochondral lesion of the talus. 1 ) and anterolateral (46%) talar dome ( 1 ). Purpose: The purpose of this study was to show that magnetic resonance imaging (MRI) can accurately and noninvasively evaluate the articular cartilage overlying osteochondral lesions of the talus, using arthroscopy as the standard, and provide information about lesion stability. Although magnetic resonance imaging (MRI) is commonly used in the preoperative evaluation of OLTs, the reliability of the MRI measurement … 3. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. The clinical outcome was recorded with ankle function scores, and MRI … MRI: Medial osteochondral lesion of the talus, with central piece of bone. Treatment of talar OCLs can be conservative or surgical, depending on whether the lesion is unstable or refractory to conservative management. Classification of osteochondral lesions of the talus using MRI. Chuckpaiwong et al. Art. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Patients and methods - This study included 142 patients w … Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. 17 Osteochondral Lesions of the Talus MARK E. EASLEY, STEVEN D. SIDES, AND ALISON P. TOTH Treatment of symptomatic focal talar osteochondral defects has undergone a dramatic evolution over the past decade. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. However, the lesion exhibits various conditions even … Background and purpose - The frequency of progression of osteoarthritis and persistence of symptoms in untreated osteochondral lesion of the talus (OCL) is not well known. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. MRI of the ankle is performed to assess the ligaments, bones, and articular cartilage as well as the tendons and other soft tissues of the ankle joint [1, 2].Osteochondral lesions of the talar dome are a frequently encountered abnormality on MRI examination of the ankle. Slight increase in degenerative changes of the ankle with limited cartilage damage of anterior distal tibia. 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). Osteochondral lesions of the talus are diagnosed with a medical history, thorough physical examination, X-rays, CT and MRI. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. … 1, pp. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Foot Ankle Int . Fig. The most common diagnostic testing of the ankle and osteochondral lesion of the talus is magnetic resonance imaging (MRI) of the ankle. Lesion size is a major determinant of treatment strategy for osteochondral lesions of the talus (OLTs). Total lesion size unchanged. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Magnetic resonance imaging (MRI) is the gold standard for evaluating osteochondral lesions and one should order this for chronic ankle pain unresponsive to nonsurgical care. Magnetic resonance imaging (MRI) of the ankle joint. They may also be called osteochondritis dessicans or osteochondral fractures. Nonoperatively managed stage 5 osteochondral talar lesions. The presence of an osteochondral lesion may initially go undetected and may manifest many months after the initial ankle injury. They followed up 25 patients with osteochondral lesions in the talus and treated with arthroscopic microfracture. SCIENTIFIC ARTICLE Osteochondral lesion of the talus in children: Are there MRI findings of instability? (c) T-2 Maya Patel1 & Michael L. Francavilla2,3 & J. Todd R. Lawrence3,4 & Christian A. Barrera2 & Michael K. Nguyen2 & Cruz Longoria5 & Jie C. Nguyen2,3 Received: 12 January 2020 /Revised: 23 March 2020/Accepted: 30 March 2020 An Osteochondral Lesion of the Distal Tibia and Fibula in Patients With an Osteochondral Lesion of the Talus on MRI: Prevalence, Location, and Concomitant Ligament and Tendon Injuries. CT is used to accurately diagnose the size of the lesion … Magnetic resonance imaging (MRI) is useful for evaluating the stability of an osteochondral lesion of the talus (OLT). Increased cyst formation compared to images of 2011, but diminished bone oedema. Historically, a variety of terms have been used to refer to this clinical entity including osteochondritis dissecans, osteochondral fracture, and osteochondral defect. Arthroscopic management of transchondral talar dome fractures (osteochondritis dissecans) and anterior impingement lesions of the ankle joint. Osteochondral lesions of the talus: change in MRI findings over time in talar lesions without operative intervention and implications for staging systems. Purpose: The purpose of this study was to compare outcomes of chondroplasty versus microfracture versus osteochondral autologous transplantation (OAT) in patients with osteochondral lesions of the talus (OLT).Methods: After prospective sample size analysis, patients with symptomatic, recalcitrant Ferkel class 2b, 3, and 4 OLT were randomized to chondroplasty, microfracture, or OAT … Develop insidiously is an injury to the cartilage and underlying bone of the dome!
