It is uncertain whether these OLT or conventional OCD (best studied in the knee) represent differ-ent manifestations of a common pathologic process or sepa-rate pathologies. The most common sites are the posteromedial (53%) (Fig. Overlying cartilage may degenerate . When compared to medial talar OCDs, which of the following statements is true regarding lateral talar OCDs? Free, official coding info for 2021 ICD-10-CM M93.279 - includes detailed rules, notes, synonyms, ICD-9-CM conversion, index and annotation crosswalks, DRG grouping and more. Osteochondritis dissecans can be classified at surgery into 4 stages: stage I. stable; lesion in continuity with the host bone; covered by intact cartilage; stage II. Although the cartilage cap remains viable (. - can have family history of talus OCD . 2016 2017 2018 2019 2020 2021 Billable/Specific Code. The injury occurring on the medial aspect of the Talus is often deeper and cup shaped. Figures A and B are radiographs of the left ankle. Tested Concept, Total contact cast immobilization and nonweight-bearing for 6 weeks, (OBQ12.74) Osteochondritis dissecans (OCD) of the talus is a disea-se affecting the subchondral bone and secondarily the articular cartilage. - Gregory Berlet, MD, Foot & Ankle⎪Osteochondral Lesions of the Talus, Asymptomatic Medial Talar Dome OCD in a 17M, Osteochondral Lesions of the Talus with Midfoot Arthritis, Talus fracture, OCD, cartilage fragment, subchondral cyst. A 43-year-old male sustained a left ankle injury 3 years ago. 1 ) and anterolateral (46%) talar dome ( 1 ). 1) and anterolateral (46%) talar dome (1). The coronal plane of the MRI demonstrates anteromedial lesions of OLT, Hepple stage 1 and 2A in figure 2A, and 2B (arrow), respectively. The mean time of follow-up was 36 months (range, 25-49). More complex scaffolds that better replicate the microarchitecture of articular cartilage may become available. Osteochondral lesions of the talus. 1–3 Two common lesions are notable on the talus. Berndt & Harty Xray Classification . Perform general foot and ankle examination. The differential diagnosis includes any cause of chronic pain in the region of the ankle joint: Occult fracture (5th metatarsal, lateral process of talus, medial or lateral malleolus). When osteochondritis dissecans affects the ankle it typically occurs on the inner or medial portion of the ankle (talus). Treatment principles of osteochondral lesions of the ta… - can have family history of talus OCD . The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Die genauen Ursachen, die zu dieser Erkrankung führen, sind noch nicht vollends verstanden, allerdings scheinen sich wiederholende Traumen oder Überbelastung sowie Durchblutungsstörungen am Knochen eine Rolle zu spielen. Metal artifact can make MRI difficult to interpret in certain cases. Copyright © 2020 Lineage Medical, Inc. All rights reserved. What would be the next most appropriate step for treatment? 3 A debridement of the chondral part is required if symptomatic. Osteotomy usually is required as part of the surgical approach. 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). If a lesion is seen on plain radiographs, Best method for accurately characterizing the size and extent of a defect, Tends to overestimate the size of a lesion because of bone marrow edema. [] Although majority may be associated with trauma, some may develop insidiously. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. If the subchondral bone is violated, the defect attempts to heal with fibrous tissue or fibrocartilage. Die Osteochondrosis dissecans (kurz OCD bzw. The mean size of defect of OCD was 13.6 mm × 7.2 mm. ACI is a 2-stage procedure in which hyaline cartilage is harvested from the anterior aspect of the talus or a nonweightbearing portion of the knee in the first stage. Stage 3 • Nondisplaced lesion with lucency: Stage 4 • Displaced fragment Radiographs are unremarkable. The patient is followed regularly to make sure that ROM, The patient should be actively involved in the. Treatment algorithm for OLT lesions overlaps with the treatment for OCD and depends on lesion stability. Arthroscopy provides the best and most direct method for evaluating the articular surface and treating the abnormality. Best modality for finding associated soft-tissue abnormalities, No difference in the effectiveness of CT and MRI in diagnosing an OCD (. Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3–5). 3rd-generation techniques rely on a 3D bioscaffold to contain the cells instead of a periosteal flap (, Short-term clinical results generally are. The average age at surgery was 22.7 years (range, 19-34). This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Traumatic chondral defects, on the other hand, are often related to shear. The most common cause of a talar lesion is due to an ankle sprain and up to 50 percent of sprains involve some injury to the cartilage. Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. Q: How are unstable OCD lesions of the ankle treated? OCD of the talus usually occurs in patients aged between 10 and 40 years, and it peaks in the second decade of life. OCD usually causes pain during and after sports. Stage 1 - subchondral compression fracture . He complains of mechanical symptoms with ankle movement that continue to be symptomatic with everyday activities. 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, ankle inversion and dorsiflexion during axial load creates shearing of lateral talar dome and lateral OLT, ankle inversion, external rotation, and plantarflexion during axial load creates shearing of medial talar dome and medial OLT, possible repeitive microtrauma creates ischemic environment and loss of integrity of subchondral bone, leads to softening and disruption of overlying cartilage, among the thickest in the body (implications for osteochondral autografting), maintains tensile strength longer than femoral head with aging process, deltoid artery supplies majority of talar body and dome. Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): Talar hemiarthroplasty Using a metallic prosthesis for OCL of the talus was first described in 2010 for a defect of the medial talar dome in a cadaver [37]. The sagittal MRI demonstrates non-displaced mid-medial lesion of OLT, Hepple stage 3, in figure 2E (arrow) and displaced mid-lateral lesion of the OLT, Hepple stage 4, in (Fig. Cartilage damage was noted in 17–66% of ankles with lateral ligament injuries [ 3 , 12 , 21 , 26 ]. Pathology . Physical examination elicits pain with ankle dorsiflexion and plantarflexion, although subtalar motion is normal. A 21-year-old male reports right ankle pain after sustaining an inversion ankle injury 2 years ago. Eighteen symptomatic advanced-stage osteochondritis dissecans (OCD) of the talus (Berndt and Harty stages III 7 and IV 11) in 17 patients were treated with multiple autogenous osteochondral cylindrical grafts. Depending on how the ankle is injured, the problem can occur on the side of the talus closest to the other foot or on the outside part. Weak evidence suggests that a genetic component might be involved in some OCDs (, OCDs can be produced in cadaveric models by shear and compression forces (, Chronic: Recurrent injury from chronic ankle instability, Lateral OCD is associated with a recognized traumatic episode in 93% of cases (, Medial OCD is associated with a recognized traumatic episode in 61% of cases (. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. Other possible causes include ischemic events (AVN). All Rights Reserved. MRI staging system for osteochondral lesion of the talus. • Cartilage injury with underlying fracture and surrounding bony edema, • Stage 2a without surrounding bone edema, often limited secondary to pain or effusion, evaluate for ligamentous laxity or insufficiency, suspicion for OLT in setting of equivocal radiographs, helpful in evaluating subchondral bone and cysts, less reliable in purely cartilaginous lesions of nondisplaced OLTs, provides fine detail of lesions for pre-operative planning, persistent pain following injury, ankle sprains that do not heal with time, variable edema patterns, may overestimate degree of injury, unstable lesions show fluid deep to subchondral bone, predicts stability of lesion with 92% sensitivity, nondisplaced fragment with incomplete fracture, size > 1 cm and displaced lesions, shoulder lesions, salvage for failed marrow stimulation or drilling, period of immobilization in cast or boot for 6 weeks, followed by progressive weight bearing with physical therapy emphasizing peroneal strengthening, range of motion, and proprioceptive training, Arthroscopy with marrow stimulation (microfracture or antegrade drilling), debridement of unstable cartilage flaps to create stable and contained defect using curettes or shaver, loose bodies and cartilage removed using shaver or grasper, microfracture awl placed perpendicular to surface and tapped into subchondral bone 2-4 mm deep, inflow stopped to allow fat or blood to emanate from holes, indicating adequate penetration, Kirschner wire can be passed using anterior portals, or transmalleolar for central or posterior lesions, talus dorsiflexed and plantar flex to necessitate only 1 transosseous passing of wire, articular cartilage delamination and graft failure, 65-90% improvement in patient reported outcomes, fibrocartilage formation at site of lesion in 60% of patients on second-look arthroscopy, no correlation noted with patient outcomes, Arthroscopy with retrograde drilling and bone grafting, evaluate cartilaginous surface for softening, dimpling with probe seen, Kirschner wire drilled from sinus tarsi into defect, fluoroscopy often helpful to confirm location, if bone grafting indicated, cannulated drill placed over K wire, Osteochondral autograft and allograft transplant, dictated by location of OLT and concomitant procedures required (i.e. In patients with OCD lesions of the dome of the talus, MRI is useful for preoperative evaluation. With proper treatment, the prognosis generally is good. Although Magnetic Resonance Imaging (MRI) at 1.5 Tesla is the leading cross-sectional modality for detection and staging of OCL, lack of … The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. We'll assume you're ok with this, but you can opt-out if you wish. The goal in osteochondral defects of the talus in Stages I and II according to Berndt and Harty is revascularization of the lesion. 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. This term refers to a wide spectrum of pathologies including mild bone marrow contusion as well as severe osteoarthritis resulting from long standing disease. Loomer R, Fisher C, Lloyd-Smith R, et al. Evaluate for tenderness over the talar dome. • Open articular surface lesion with the overlying nondisplaced fragment. Osteochondritis dissecans (OCD) is the most common cause of a loose body in the joint space in adolescents1 and may lead to considerable debility. Start as acute intra-articular fracture . The options for treating OCL are numerous and a number of surgical procedures can be performed arthroscopically. These lesions can be chronic in nature, as seen in Osteochondritis Dissecans (OCD). Technique guide are not considered high yield topics for orthopaedic standardized exams including the ABOS, EBOT and RC. stable on probing; partial discontinuity of the lesion from the host bone; stage III. If the subchondral bone is not violated, no healing occurs. Acute fractures do better than chronic lesions. Die OCD kann die meisten Gelenke des men… Physical therapy and NSAID's have not alleviated the symptoms. It often develops above a bone cyst. Most cases of osteochondritis dissecans of the talus occur around the time of skeletal maturity (10-14 years of age for girls and 12-16 years of age for boys). Osteochondritis dissecans, unspecified ankle and joints of foot. The incidence of osteochondral defects (OCD) of the talus is 0.09 % in the literature with a prevalence of 0.002 per 100,0001-3. Growth factors and the use of mesenchymal stem cells also will be important in refining the procedure and improving results. 6,51 This cartilage is cultured to grow chondrocytes, which can be viable for longer than 1 year. Stage 2 - partially attached osteochondral fragment / flap . ankle is a highly congruent mortise joint, oriented 15 degrees externally from midsagittal line of ankle, talus articulates with the medial malleolus medially, tibial plafond superiorly, posterior malleolus posteriorly, and fibula laterally. The top of the talus is part of the joint and is covered with articular cartilage , … Cyst may develop under fragment . The authors of this study have since published the clinical outcome of one case with good improvement in functional scores and return to sports after one year. Although biomechanically inferior to hyaline cartilage, fibrocartilage formation appears to be sufficient for smaller lesions. ROM usually is started 2–6 weeks after surgery, depending on the quality of the osteotomy fixation. Coronal T1-weighted image of the ankle, showing a medial talar OATS. Die Osteochondrosis dissecans (OCD, auch angloamerikanisch Osteochondritis dissecans) ist die umschriebene aseptische Knochennekrose unterhalb des Gelenkknorpels, die mit der Abstoßung des betroffenen Knochenareals mit dem darüberliegenden Knorpel als freier Gelenkkörper enden kann. • Complete fragment detachment but not displaced. However, in early stages, the cartilage layer is intact, and the lesions may not be seen at arthroscopy. (OBQ13.46) Other surgical options: Concurrent chronic ankle instability should be addressed with ligament reconstruction. Osteochondral lesion (OCL) is a term used to describe an injury or abnormality of the articular … Bei der Osteochondrosis dissecans stirbt ein Teil des Knochens unterhalb des Gelenkknorpels ab, sodass sich dieser ablösen kann und in der Gelenkhöhle lose vorliegt (Dissektat). ACI is a 2-stage procedure in which hyaline cartilage is harvested from the anterior aspect of the talus or a nonweightbearing portion of the knee in the first stage. Osteochondral defects of the talus is aseptic bone necrosis. Subchondral bone is penetrated to allow bleeding and fibrin clot formation. The top of the talus is dome-shaped and is completely covered with cartilage (connective tissue that allows the ankle to move smoothly). If the loosened piece of cartilage and bone stays in place, you may have few or no symptoms. KEY FACTS • The natural history of osteochondral lesions of the talus appears to be fairly benign, especially as it relates to the risk of the development of arthritis. 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). He has been treating his symptoms with physical therapy and anti-inflammatory medications with little effect. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain Bony fragment may - revascularise & unite - undergo AVN & not unite . Examine for crepitus or mechanical signs with ankle ROM. Osteochondritis dissecans(OCD) is a problem that causes pain and stiffness of the ankle joint. Sie kann die meisten Gelenke des menschlichen Körpers betreffen, sie tritt aber vor besonders häufig im oberen Sprunggelenk … Ankle ROM exercises, peroneal strengthening, progressive ambulation, and proprioception training. unstable on probing; fragment not dislocated; complete discontinuity of the "dead in situ" lesion; stage IV Berndt AL, Harty M. Transchondral fractures (osteochondritis dissecans) of the talus. Overlying cartilage may degenerate . The MRI demonstrates the osteochondral lesions of the talus (OLT). There is an increasing prevalence of … 1. The lateral injuries to the Talus (ankle bone) are usually shallow and cup shaped. Es verbleibt dann ein Gelenkflächendefekt (Mausbett). the talus” (OLT) [10]. Giannini S, Vannini F. Operative treatment of osteochondral lesions of the talar dome: current concepts review. Procedures that transfer hyaline cartilage to the defect: OATS/mosaicplasty, allograft transfer, Generally recommended for large lesions or lesions that fail other forms of treatment. The diagnosis of OCD most frequently depends on obtaining an imaging study: Plain radiographs or CT, MRI, or bone scans. OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. Osteochondral lesions of the talus. The bone lesions on the lateral or outside portion of the talus are most often related to trauma. When not displaced, a chronic osteochondral fragment often is attached to the defect by fibrous tissue. It is thought that mesenchymal stem cells in the clot lead to the formation of fibrocartilage. • Cystic lesion within dome of talus with an intact roof on all view, • Cystic lesion communication to talar dome surface. However, for the last six months, he has developed persistent ankle pain with intermittent swelling. It can occur in all age groups. The axial MRI demonstrates mid-medial lesions of … It is also called an osteochondral defect (OCD) or talar osteochondral lesion (OCL). Table 3. These lesions are of high clinical relevance as they are commonly missed … Berndt & Harty Xray Classification .

Giannini S, Buda R, Grigolo B, et al. Procedures that reduce and stabilize the displaced fragment: Usually recommended only for lesions that are large enough to be amenable to internal fixation. The ankle is the third most frequently affected site, after the knee and elbow, and it accounts for 4% of all OCD cases (1, 2). Make sure the patient does not have other. Treatment is thus most appropriately based on the patient's symptoms, a very relevant fact given that many osteochondral lesions are incidental findings. OD, angloamerikanisch auch Osteochondritis dissecans) ist eine umschriebene Knochenläsion unterhalb des Gelenkknorpels, die mit der Abstoßung des betroffenen Knochenareals mit dem darüberliegenden Knorpel als freier Gelenkkörper (Gelenkmaus) enden kann. Maire-Clare Killen and Rajiv Limaye shed light on a path of treatment that is constantly evolving. INTRODUCTION. On the lateral aspect of the ankle it most often occurs from trauma. In the ankle OCD can occur anterolateral or posteriomedial. Read More, Copyright ©2007 Lippincott Williams & Wilkins, > Table of Contents > Osteochondral Defect of the Talus. Microfracture or drilling: 4–6 weeks of nonweightbearing is recommended to allow the defect to heal, with ankle ROM encouraged. During his workup, an MRI shows a 1x1 cm lateral talar osteochondral defect (OCD). Once enough cells are available, the chondrocytes are reimplanted into the defect. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Letts M, Davidson D, Ahmer A. Osteochondritis dissecans of the talus in children. Brostrum), medial malleolar osteotomy for medial and posterior lesions, longitudinal incision centered over medial malleolus, flexor retinaculum released posteriorly; PTT retracted posteriorly, osteotomy guided based of 2 parallelly placed K-wires, with goal to enter plafond at lateral extent of OLT, prior to osteotomy, 2 drill holes placed to aid in reduction following procedure, sagittal saw and osteotome used to complete osteotomy, care taken not to cause thermal necrosis to bone or damage cartilage, lateral malleolar osteotomy or ATFL/CFL release for lateral lesions, longitudinal incision centered over lateral malleolus, oblique osteotomy planned, with predrilling of small fragment screws holes to aid in reduction following procedure, alternatively, if lateral ligament reconstruction is planned, extensor retinaculum may be released, peroneal tendons retracted posteriorly and ATFL and CFL released, ankle inverted and plantarflexed to expose talar dome, OLT debrided and measured using sizing guide, appropriately sized autograft may be harvested from knee and placed into OLT, impacted gently into defect, OATs harvested from the knee have a cartilage thickness less than the native talus, this will cause immediate post-operative xrays to show a prominent graft despite the cartilage surface being flush, do not release deltoid ligament as may jeopardize deltoid artery blood supply, ankle impingement if graft plug left proud, small percentage of patients do not achieve pain relief regardless of treatment, Posterior Tibial Tendon Insufficiency (PTTI), lesions may progress to involve entire ankle joint, mechanical symptoms such as catching or locking, arthroscopic harvest of chondrocytes (from ankle or alternatively from knee) are sent for cultured growth, open approach via osteotomy for implantation, debridement of lesion to create stable cartilage rim, subchondral bone exposed, bone graft may be placed if underlying cyst and bone loss, periosteum from tibia taken and fitted to defect, this is sutured into place this small caliber suture, omitting one area to leave access to underlying defect, water-tight seal confirmed, cultured chondrocytes placed under flap and suture placed, fibrin glue placed over defect, newer technique of matrix-based chondrocyte implantation (MACI) shown equivalent outcomes to ACI and may obviate need for osteotomy. Radiography cannot directly depict the cartilage surface (3). Osteochondritis dissecans (OCD) is an aseptic bone necrosis and represents pathology of high clinical relevance, which is frequently located on the talus. Defined as a separation of articular cartilage from the talar dome, with varying amounts of subchondral bone. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Bony fragment may - revascularise & unite - undergo AVN & not unite . Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. Nonoperative management recommendations range from activity modification alone to nonweightbearing in a cast. Tested Concept, Avoidance of dancing with CAM walker boot for 2 weeks, Type in at least one full word to see suggestions list, 2019 Orthopaedic Summit Evolving Techniques, Debridement And Abrasion: It's Simple And Yields Great Results: Watch Me! (, No clear method is available for preventing this, Most patients who develop OCDs are in their 2nd–4th decades, with a mean age of 26.9 years (. Dr. Ebraheim’s educational animated video describes Osteochondral Lesions of the Talus. • There are… MRI is less useful for determining healing of OCD lesions because clinical healing may not correlate with imaging [ 5,20 ], and, in patients with operative repair, bony edema from instrumentation interferes with identification of healing during the postoperative period [ 44 ]. Delaying surgical intervention for chronic OCD does not appear to alter results of later surgery. [ 2 ] © 2020 - TeachMe Orthopedics. Stage 1 - subchondral compression fracture . Weightbearing radiographs should be obtained initially. Pathology . Examine for ankle instability (anterior drawer test, talar tilt test) or evidence of general ligamentous laxity. Procedures that regrow hyaline cartilage, such as autologous chondrocyte transfer: Cartilage is harvested (usually from the knee) and grown in culture. Children are thought to have better healing potential than adults. The average age at surgery was 22.7 years (range, 19-34). Stable “Osteo” means bone and “chondral” refers to cartilage. Santrock RD, Buchanan MM, Lee TH, et al. The most common sites are the posteromedial (53%) ( Fig. The historical term for this grouping of pathologies, osteochondritis dissecans (OCD), emphasized a localized vascular deficiency within the talus as the principle pathology with the symptoms being secondary to loss of adequate chondral support &/or cyst formation within the talus. Osteochondral lesions of the talus and the role of ankle arthroscopy. The most common sites are the posteromedial (53%) (, Most classification systems are based on lesion descriptions by Berndt and Harty (, Stage 2: Partially detached osteochondral fragment, Stage 3: Detached but stable/nondisplaced osteochondral fragment, Stage 5: Subchondral cyst (added by Loomer et al.)
