The study was a review of case records of patients between January 2016 and December 2019 who were diagnosed with osteochondral lesion of the talus and were treated with arthroscope-assisted retroarticular drilling and autologous cancellous bone grafting. Thieme, 2006. A microfracture technique of osteochondral lesion of the talus is demonstrated. Check for errors and try again. The term osteochondritis dissecans has persisted, and has since been broadened to describe a similar process occurring in many other joints, including the knee, hip, elbow, and metatarsophalangeal joints . We studied the incidence of osteochondral lesions of the talus (OCLT) with various ankle fracture patterns and assessed their impact on functional outcome. A study by Verhagen and colleagues found MRI has a greater sensitivity in comparison to computed tomography (CT). Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Imaging strategies for the knee. Dieser Teil des Sprungbeins bildet mit dem unteren Schien- und Wadenbein das sogenannte obere Sprunggelenk. netic resonance imaging [MRI]), has been targeted as a viable entity to treat in a therapeutic strategy to relieve pain.2 Inhibition of subchondral lesions has been shown to alleviate joint pain.1 Several arthroscopic and open sur-gical techniques have been used to address subchondral disease, including osteochondral autograft and allograft,3 Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. INTRODUCTION. There is also a bone on top of the talus. 6.1. Patients may report acute, chronic repetitive, or minimal but distinct traumatic events or no trauma at all. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondral defects of the talus (OCD) are a well-established pathology within the ankle. Introduction. cartilage injury with associated subchondral fracture but without detachment 10 Because these lesions typically are undiagnosed, these numbers may be inordinately low. Cuttica DJ, Shockley JA, Hyer CF, Berlet GC. When planning the treatment of osteochondral lesions of the talus, it is important to evaluate the articular cartilage to distinguish between stable and unstable lesions (1,2).Radiography cannot directly depict the cartilage surface ().Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3 –5). 2010). Onset is between childhood and middle age, with the majority of patients being between 10 and 40 years of age, with approximately a 2:1 male to female ratio 3. 2,5,14,28,30,41,42 Up to 70% of ankle trauma may entail some form of chondral or osteochondral injury, 1 and thus OLTs are a topic of increasing interest. Intraoperatively, the lesions … Novel Application of Magnetic Resonance Imaging Demonstrates Characteristic Differences in Vasculature at Predilection Sites of Osteochondritis Dissecans. Though there is some evidence that the high grade lesions do less well with an arthroscopic debridement and microfracture this is a much smaller operation than open grafting and a number will settle with no more intervention required.

Mechanical malalignment overloads either the medial or lateral boarders of the talus depending if there is tibial or hindfoot varus or valgus . Osteochondritis dissecans (OCD or OD) is a joint disorder primarily of the subchondral bone in which cracks form in the articular cartilage and the underlying subchondral bone. Of the remaining 7 lesions, all were identified within 1 grade. Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. Thieme, 2006. Perform the initial testing without contrast dye injection. It also aids in the assessment of stability and determination of the presence of a cystic component. With an estimated incidence of 27 per 100 000 person-years, these lesions are not uncommon. As such, it can go on to produce a partially or completely detached osteochondral fragment [ 1 – 3 … Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. Conclusions: This study shows that MRI can be used to evaluate the articular cartilage covering osteochondral lesions of the talus … Ferkel RD, Zanotti RM, Komenda GA et-al. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. When analyzing osteochondral lesions on MR images of the knee, the radiologist must first consider patient demographics, clinical presentation, and history of trauma. talus; capitellum of the humerus; Staging. Radiographic features Plain radiograph and CT. 2010;31(1):90-101. On review of all literature describing transchondral fractures of the talus, Berndt and Harty developed a classification system for staging of osteochondral lesions of the talus (OLTs). Follow-up study of MRI for osteochondral lesion of the talus. Perform the initial testing without contrast dye injection. 3. We report the outcome of a nonoperative treatment for symptomatic OCL. 3. This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL). Thompson JP, Loomer RL. OLTs typically are preceded by a traumatic event and generally result in vascular damage to the subchondral bone. Arthroscopic grade A and F showed good correlation (80 and 100%). J Bone J Joint Surg Br. Annals of Clinical and Analytical Medicine; inquiry The ankle joint is an articulation of the end of the tibia and fibula (shin bones) with the talus (heel bone). incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral; medial talar dome lesions more common; location medial talar dome. 3 illustrates the classification of osteochondral lesions of the talus using MRI. With recent advances in arthroscopic techniques, the number of operations for OCL is increasing (van Dijk et al. They are most commonly associated with ankle trauma and wh… Osteochondral injuries are graded according to the stability and location of the fragment and presence of secondary degenerative changes (see: osteochondral injury staging). Maeurer Juergen. The OCLT was graded as follows: 0, … It is often associated with a traumatic injury, such as a severe Later on, this grading system has been modified to computed tomographic evaluation and correlated with arthroscopy, distinguishing cystic lesion of talar dome seen in primary stages with or without communication to the articular The incidence of OLTs is only 0.09% of all fractures and 1% of talus fractures. A number of repair strategies exist, including microfracture, osteochondral autograft transfer, and cell-based transplantation techniques, but each has its own limitations. Figure 2 (right): 28 y.o.
