Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. 1959. Magnetic resonance imaging of the elbow: update on current techniques and indications. 1 ) and anterolateral (46%) talar dome ( 1 ). Letts M, Davidson D, Ahmer A. Osteochondritis dissecans of the talus in children. Osteochondral lesions (osteochondritis dissecans) of the talus are common articular lesions that are usually traumatic in origin. When it becomes necrotic, the overlying cartilage is devitalized, and frequently the entire fragment separates out and forms an intra-articular loose body. 24, No. We studied the value of MR imaging in determining the stability of the osteochondral fragments. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Osteochondritis dissecans is an aseptic necrosis of subchondral bone and the overlying cartilage. 7 Simultaneous surgery for chronic lateral ankle instability accompanied by only subchondral bone lesion of talus It can occur in all age groups. Flynn JM, Kocher MS, Ganley TJ. MRI-guided percutaneous retrograde drilling of osteochondritis dissecans of the talus: a feasibility study 17 April 2014 | European Radiology, Vol. Osteochondritis dissecans of the talus | Radiology Case ... ... . This retrospective IRB-approved and HIPPA-compliant study included children with OLT, who underwent an ankle MRI examination between March 1, 2011, and May 31, 2018. J Bone Joint Surg [Am]. Berndt AL, Harty M. Transchondral fracture (osteochondritis dissecans) of the talus. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): Role of magnetic resonance imaging and clinical criteria in predicting successful nonoperative treatment of osteochondritis dissecans in children. Brunton LM, Anderson MW, Pannunzio ME, et al. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. J Pediatr Orthop 2003; 23:617. 1 A 26-year-old housewife presented with chronic ankle pain for 3 weeks duration with intermittent swelling after exertion, without any history of trauma. Osteochondritis dissecans has been reported to affect the ankle as the third most common joint, after the knee and the elbow. 41(A):988-1020. Osteochondritis dissecans of the knee. J Hand Surg Am 2006; 31:1001. Osteochondritis dissecans (OCD) is a problem that causes pain and stiffness of the ankle joint. The most common sites are the posteromedial (53%) ( Fig. 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. It can occur in all age groups. Clinical management of these lesions is based on whether or not the fragments are attached. Pill SG, Ganley TJ, Milam RA, Lou JE, Meyer JS, Flynn JM. Osteochondritis dissecans (OCD) of the talus is a subchondral bone pathology that presents as an osteochondral lesion of the talar dome with consequent articular cartilage abnormalities. Osteochondral lesions of the talus can be associated with injury to the ankle. Osteochondritis dissecans of the talus is a subset of osteochondral lesions of the talus that also includes osteochondral fractures, avascular necrosis, and degenerative arthritis. Usually a small area of bone adjacent to the articulating surface is affected. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. This article discusses the anatomy, path … Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome.
