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. Nonoperative management recommendations range from activity modification alone to nonweightbearing in a cast. When osteochondritis dissecans affects the ankle it typically occurs on the inner or medial portion of the ankle (talus). Evaluate for tenderness over the talar dome. Examine for crepitus or mechanical signs with ankle ROM. The top of the talus is dome-shaped and is completely covered with cartilage (connective tissue that allows the ankle to move smoothly). stable on probing; partial discontinuity of the lesion from the host bone; stage III. 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). Cartilage damage was noted in 17–66% of ankles with lateral ligament injuries [ 3 , 12 , 21 , 26 ]. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. • Cystic lesion within dome of talus with an intact roof on all view, • Cystic lesion communication to talar dome surface. 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 (. Dr. Ebraheim’s educational animated video describes Osteochondral Lesions of the Talus. Die Osteochondrosis dissecans (kurz OCD bzw.

This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Physical examination elicits pain with ankle dorsiflexion and plantarflexion, although subtalar motion is normal. - can have family history of talus OCD . Die OCD kann die meisten Gelenke des men… The lateral injuries to the Talus (ankle bone) are usually shallow and cup shaped. Berndt & Harty Xray Classification . Most classification systems are based on lesion descriptions by Berndt and Harty ( 2 ): The mean time of follow-up was 36 months (range, 25-49). 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. Osteochondral lesions of the talar dome can cause significant functional impairment and a decreased quality of life. Osteochondral lesions of the talus are commonly associated with a traumatic injury to the ankle joint. • There are… Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. We'll assume you're ok with this, but you can opt-out if you wish. Figure C shows the corresponding MRI. 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. It often develops above a bone cyst. (, 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 (. 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. • Open articular surface lesion with the overlying nondisplaced fragment. © 2020 - TeachMe Orthopedics. (OBQ13.46) Treatment is thus most appropriately based on the patient's symptoms, a very relevant fact given that many osteochondral lesions are incidental findings. Stage 1 • Cystic lesion within dome of talus with an intact roof on all view: Stage 2a • Cystic lesion communication to talar dome surface: Stage 2b • Open articular surface lesion with the overlying nondisplaced fragment. The most common sites are the posteromedial (53%) (Fig. Most cases of OCD usually follow a twisting injury to the ankle and are actually fractures of the joint surface. OCDs of the talus represent damage to the articular surface of the talar dome in the ankle joint. Humeral Shaft Fractures: Intramedullary Nailing, Humeral Shaft Fractures: Open Reduction Internal Fixation, Fractures of the Coronoid and Complex Instability of the…, Hip Arthroplasty for Intertrochanteric Hip Fractures, ACL Tear: Management in Skeletally Immature Athletes, Snapping Scapula and Winging of the Scapula, Chronic Posterolateral Rotatory Instability of the Elbow, Posterior Shoulder Instability: Diagnosis and Treatment, Thoracolumbar Decompression: Anterior and Posterior, This website uses cookies to improve your experience. Although the cartilage cap remains viable (. Fig. 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 ]. Examine for ankle instability (anterior drawer test, talar tilt test) or evidence of general ligamentous laxity. When compared to medial talar OCDs, which of the following statements is true regarding lateral talar OCDs? The mosaicplasty technique for osteochondral lesions of the talus. Although OCD of the talus is, by definition, detachment of an osteochondral fragment of the talar dome occurring in a growing patient, symptomatic OCD is more typically observed in adults. 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. The mean size of defect of OCD was 13.6 mm × 7.2 mm. The goal in osteochondral defects of the talus in Stages I and II according to Berndt and Harty is revascularization of the lesion. Copyright © 2020 Lineage Medical, Inc. All rights reserved. Doctors stage osteochondritis dissecans according to the size of the injury, whether the fragment is partially or completely detached, and whether the fragment stays in place. [] This is a broad terminology that encompasses a variety of disorders including osteochondritis dissecans, osteochondral fractures, and osteochondral defects. Delaying surgical intervention for chronic OCD does not appear to alter results of later surgery. Children are thought to have better healing potential than adults. 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. Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3–5). Perform general foot and ankle examination. Overlying cartilage may degenerate . The area where OCD occurs is located at the top of the talus. Loose bodies, fibrous tissue, and unstable cartilage are débrided. - can have family history of talus OCD . Tested Concept, Increased incidence of traumatic etiology, (OBQ06.213) 1–3 Two common lesions are notable on the talus. 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. These lesions can be chronic in nature, as seen in Osteochondritis Dissecans (OCD). Stage 1 - subchondral compression fracture . Other surgical options: Concurrent chronic ankle instability should be addressed with ligament reconstruction. A 43-year-old male sustained a left ankle injury 3 years ago. Weightbearing radiographs should be obtained initially. 1, 24 This debridement is limited to loose The axial MRI demonstrates mid-medial lesions of … 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.

Osteochondral lesion (OCL) is a term used to describe an injury or abnormality of the articular … 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. Osteochondritis dissecans(OCD) is a problem that causes pain and stiffness of the ankle joint. • 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. This guide will help you understand 1. how OCD develops 2. how the condition causes problems 3. what can be done for your pain Sie kann die meisten Gelenke des menschlichen Körpers betreffen, sie tritt aber vor besonders häufig im oberen Sprunggelenk … However, for the last six months, he has developed persistent ankle pain with intermittent swelling. Osteochondral defects of the talus is aseptic bone necrosis. ROM usually is started 2–6 weeks after surgery, depending on the quality of the osteotomy fixation. Other possible causes include ischemic events (AVN). Pathology . 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. Es verbleibt dann ein Gelenkflächendefekt (Mausbett). More complex scaffolds that better replicate the microarchitecture of articular cartilage may become available. OCD usually causes pain during and after sports. MRI staging system for osteochondral lesion of the talus. Bony fragment may - revascularise & unite - undergo AVN & not unite . unstable on probing; fragment not dislocated; complete discontinuity of the "dead in situ" lesion; stage IV The options for treating OCL are numerous and a number of surgical procedures can be performed arthroscopically. 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. The diagnosis of OCD most frequently depends on obtaining an imaging study: Plain radiographs or CT, MRI, or bone scans. 3 A debridement of the chondral part is required if symptomatic. Acute fractures do better than chronic lesions. The mean time of follow-up was 36 months (range, 25-49). 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). 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. If the subchondral bone is not violated, no healing occurs. Stage 2 - partially attached osteochondral fragment / flap . Although biomechanically inferior to hyaline cartilage, fibrocartilage formation appears to be sufficient for smaller lesions. 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]. 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. On the lateral aspect of the ankle it most often occurs from trauma. Osteochondral lesions of the talus (OLT) are those that affect the chondral and subchondral areas of the talus. There is an increasing prevalence of … Autologous chondrocyte transplantation in osteochondral lesions of the ankle joint. The most common sites are the posteromedial (53%) ( Fig. Bony fragment may - revascularise & unite - undergo AVN & not unite . Berndt & Harty Xray Classification . Arthroscopy provides the best and most direct method for evaluating the articular surface and treating the abnormality. In patients with OCD lesions of the dome of the talus, MRI is useful for preoperative evaluation. Raikin SM. Microfracture or drilling: 4–6 weeks of nonweightbearing is recommended to allow the defect to heal, with ankle ROM encouraged. The average age at surgery was 22.7 years (range, 19-34). A 21-year-old male reports right ankle pain after sustaining an inversion ankle injury 2 years ago. Stage 3 • Nondisplaced lesion with lucency: Stage 4 • Displaced fragment Osteotomy usually is required as part of the surgical approach. He complains of mechanical symptoms with ankle movement that continue to be symptomatic with everyday activities. Overlying cartilage may degenerate . - 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. INTRODUCTION. 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. 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). Osteochondral lesions of the talus and the role of ankle arthroscopy. Stage VI: massive osteochondral defects of the talus. The injury occurring on the medial aspect of the Talus is often deeper and cup shaped. 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. 3rd-generation techniques rely on a 3D bioscaffold to contain the cells instead of a periosteal flap (, Short-term clinical results generally are. When not displaced, a chronic osteochondral fragment often is attached to the defect by fibrous tissue. Once enough cells are available, the chondrocytes are reimplanted into the defect. 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. Table 3. Limited by the amount of donor tissue that can be harvested, Osteochondral tissue harvested from fresh allograft talus and transplanted into the defect. 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. Osteochondral lesions of the talus. Radiographs are unremarkable. If the subchondral bone is violated, the defect attempts to heal with fibrous tissue or fibrocartilage. 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). OCD of the talus usually occurs in patients aged between 10 and 40 years, and it peaks in the second decade of life. It can occur in all age groups. 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. Giannini S, Vannini F. Operative treatment of osteochondral lesions of the talar dome: current concepts review. Osteochondral lesions of the talus. 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.) Santrock RD, Buchanan MM, Lee TH, et al. Osteochondral defect (OCD) or lesion of the talus can accompany chronic lateral ankle instability (CAI). 6,51 This cartilage is cultured to grow chondrocytes, which can be viable for longer than 1 year. The talus is the 3rd most common site (after the knee and elbow) of osteochondral lesions. Cyst may develop under fragment . Any procedure that requires an osteotomy necessitates nonweightbearing until the osteotomy heals (4–8 weeks). Stable The average age at surgery was 22.7 years (range, 19-34). Infektionen des Knochens hingegen spielen keine Rolle in der Entstehung der Osteochondrosi… Accept Complications include malunion or nonunion of an osteotomy, persistent pain, stiffness, and arthritis. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Ankle ROM exercises, peroneal strengthening, progressive ambulation, and proprioception training. Make sure the patient does not have other. Cyst may develop under fragment . Procedures that reduce and stabilize the displaced fragment: Usually recommended only for lesions that are large enough to be amenable to internal fixation. 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. Radiographs at the time were negative and his pain improved over the next two months.

Subchondral bone is penetrated to allow bleeding and fibrin clot formation. [] Although majority may be associated with trauma, some may develop insidiously. Figures A and B are radiographs of the left ankle. In later stages of the disorder there will be swelling of the affected joint which catches and locks during movement. What would be the next most appropriate step for treatment? Q: How are unstable OCD lesions of the ankle treated? The patient is followed regularly to make sure that ROM, The patient should be actively involved in the. The bone lesions on the lateral or outside portion of the talus are most often related to trauma. Letts M, Davidson D, Ahmer A. Osteochondritis dissecans of the talus in children.
