A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. In general, the best results can be expected for smaller lesions. The knee and the ankle joint are the most commonly involved joints for OCLs in the lower extremity. In children, they are most often found in the knee and elbow. Electronic databases from January 1966 to December 2006 were systematically screened. Osteochondritis Dissecans (OCD) is a condition that develops in the joints, most often in children and adolescents. OCD is an abbreviation which can stand for either Osteochondritis Dissecans or Osteochondral Defect. Osteochondral lesion of the talus (OLT) is a broad term used to describe an injury or abnormality of the talar articular cartilage and adjacent bone. The American Orthopaedic Foot & Ankle Society (AOFAS) offers information on this site as an educational service. OCD is often diagnosed with the help of an X-ray because it can easily reveal that a fragment has chipped off of the larger bone. Recovery after OLT treatment varies depending upon the nature of the lesion and the treatment. For an ankle OCD lesion, your child may be placed in a boot or cast for up to 6 weeks. Depending on the characteristics and location of the OLT, surgery may done arthroscopically or by opening the skin. Symptomatic osteochondral ankle defects often require surgical treatment. This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. 69% of … In particular cases also alternative diagnoses can be made on basis of CBCT (Figure 11). Your doctor may also recommend exercises or physical therapy to improve range of motion, strength and function. A variety of terms have been used to refer to this clinical entity, including osteochondritis dissecans (OCD), osteochondral fracture and osteochondra … 44,61,70 Classic teaching is that lateral OLTs are more likely due to trauma than medial lesions, with 94% of lateral lesions and 62% of medial lesions being caused by trauma. Lingering pain after an ankle sprain or a feeling your ankle is “stuck” or “catching” can be a sign of a bone chip in the ankle. It may not be possible to properly treat certain lesions arthroscopically due to the size or location of the lesion. OLTs usually occur after an injury to the ankle, either a single traumatic injury or as a result of repeated trauma. In my experience in 99% of these defects they can be treated in forced plantar flexion. Hip. 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). for professional medical advice, diagnoses or treatments. Osteochondritis dissecans is used when the patient is young and the cause is not exactly known, yet most probably due to repetitive microtrauma. An OCD lesion is comparable to a pot hole on the highway, once it begins the pathology will progress unless treatment is initiated. Osteochondral lesion of talus (OLT): • Only 0.09% of all fractures and 1% of all talus fractures – Traumatic etiology – Commonly: ankle sprain • Inversion injury • 6.5 per 100 ankle sprains – Bosien et al. Sometimes an ankle injury leads to damaged, rough areas of cartilage and bone underneath. The condition can be mild, moderate, or severe. Depending on the location of the bone chip, some patients feel a ‘catching’ sensation with certain ankle movements. The content is not intended to substitute Such lesions are a tear or fracture in the cartilage covering one of the bones in a joint. Osteochondritis dissecans is used when the patient is young and the cause is not exactly known, yet most probably due to repetitive microtrauma. It contains free information. Cartilage lesion on 6 mm. Lesion location, laterality, and all patient demographics were recorded. Once the diagnosis has been confirmed, treatment may be surgical or non-surgical, depending on the nature of the OLT, presence of other injuries, and patient characteristics. ... surgery may be necessary. Osteochondritis is a lesion that usually causes pain and stiffness of the ankle joint and affects all age groups. [2] That process can lead to pain, loose body formation and joint effusion.[1]  This also can confirm the size of the lesion: in case it is less then 15 mm in length on the sagital image then you can perform bone marrow stimulation. OCD most commonly affects the knee, although it can affect other joints such as the ankle or the elbow. The risk for ankle OCD for age group, sex, and ethnicity was assessed using multivariate logistic regression models. The talus sits inside the joint and allows the up and down motion of the ankle. Ankle arthroscopy plays a major role in management of these lesions, whether this is for further assessment, debridement or definitive treatment. Osteochondral lesions are injuries to the talus (the bottom bone of the ankle joint) that involve both the bone and the overlying cartilage. All surgeries come with possible complications, including the risks associated with anesthesia, infection, damage to nerves and blood vessels, and bleeding or blood clots. Epidemiology. Our podiatrists recommend: If you’ve had an ankle sprain, think you might have an OCD lesion of the talus, or are having any type of issue with one or both ankles, contact a podiatrist at Advanced Foot & Ankle of Wisconsin today. Sometimes injuries to the ankle joint are harder to heal because the blood supply to the bones of the ankle is not as abundant as elsewhere in the body. Approximately 50% of ankle sprains and up to 73% of ankle fractures result in some level of cartilage injury, and there are over 2 million ankle sprains alone per year. Without early treatment, the lesion can become unstable or completely detached. It often occurs after an injury such as a sprain or trauma to the foot and ankle. These injuries may include softening of the cartilage layers, cyst-like lesions within the bone below the cartilage, or fracture of the cartilage and bone layers. Whether the cause of your ankle pain is a bone chip fracture or other issue, our foot and ankle specialists will get to the root cause and design an effective treatment plan. Non-surgical treatment is appropriate for certain lesions and usually involves immobilization and restricted weightbearing. Ankle sprains are a common cause of OLTs. When a rolling or twisting type injury occurs, part of the talus can crush or shear against another bone in the ankle joint. However, in early stages, the cartilage layer is intact… “Osteo” means bone and “chondral” refers to cartilage. Lesions with large cystic areas, diffuse arthritic changes, ankle malalignment, and prior history of infections are contraindications to this procedure. Osteochondritis of the talus is caused by a traumatic ankle injury, commonly a rolling-inward ankle sprain. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management.. stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. Dr. Ebraheim’s educational animated video describes Osteochondral Lesions of the Talus. Most of the talus is covered by cartilage. Arthroscopy uses a camera and small instruments to view and work within the joint through small incisions. 1955 – Older age group: • 2 nd through 4 th decade • Average … Lateral talar lesions are more common than medial lesions. Maire-Clare Killen and Rajiv Limaye shed light on a path of treatment that is constantly evolving. Ankle Osteochondritis Dissecans. Osteochondral lesions of the talus (OLT) are ankle joint injuries involving damage to the joint surface (cartilage) and/or underlying ankle bone (talus). Osteochondral lesions are most common in the knee joint, and the ankle is the next most frequent joint affected. When osteochondritis dissecans affects the ankle it typically occurs on the inner or medial portion of the ankle (talus). Our podiatrists accept insurance (including Medicaid & Medicare) and we’re happy to do a coverage check if you bring your plan information. Osteochondral lesions of the talus and the role of ankle arthroscopy. Common symptoms include prolonged pain, swelling, catching, and/or instability of the ankle joint. cartilage injury with associated subchondral fracture but without detachment Common symptoms include prolonged pain, swelling, catching and/or instability of the ankle joint. OCD is a type of osteochondrosis in which a lesion has formed within the cartilage layer itself, giving rise to secondary inflammation. The blood supply to the talus is not as rich as many other bones in the body, and as a result, injuries to the talus sometimes are more difficult to heal than similar injuries in other bones. OCD is most common in the knee joint, but it can happen in other joints such as the elbow and ankle. An OCD lesion of the ankle is a specific type of injury to the bottom bone in the ankle joint. American Orthopaedic Foot & Ankle Society, The American Orthopaedic Foot & Ankle Society (AOFAS) offers information on this site as an educational service. If your symptoms linger longer than expected, or if your ankle injury is severe enough to warrant an X-ray, you’ll head in for imaging tests. Occasionally, regular X-rays can show an OLT but frequently additional imaging is needed, such as a CT scan or an MRI. Foot & Ankle. Both magnetic resonance (MR) imaging and ankle arthroscopy are excellent tools commonly used to evaluate ankle cartilage (3–5). Preventing osteochondral lesions means avoiding traumatic ankle injuries such as sprains. The condition typically affects just one joint, however, some children can develop OCD in several joints. In this regard, CBCT-Arthrography (CBCT-A) may be very promising technique for precise staging of cartilage lesions of the ankle as an alternative for Multi Detector Computed Tomography (MDCT). Regional skeletal maturity and older age were more predictive of unstable lesions. The risk for ankle OCD for age group, sex, and ethnicity was assessed using multivariate logistic regression models. Members receive the 'Picture of the week', new operative techniques and can submit their problem cases for an expert opinion. If the blood supply to the talus is compromised by an injury, it could cause an area of the bone to die, resulting in a chip fracture. It is often associated with a traumatic injury such as a … Much of this bone is covered with cartilage. The goal of non-surgical treatment is to allow the injured cartilage and bone to heal. This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondral lesions of the talus are a reasonably infrequent cause of long-standing ankle pain and stiffness and are often the result of a severe ankle sprain type injury. Osteochondritis dissecans (OCD) is a localized injury or condition affecting an articular surface that involves separation of a segment of cartilage and subchondral bone (Schenck, 1996). It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). OCD is characterized by a loss of blood supply to one or more bones in the ankle, which may result in a fracture or break within the ankle joint. This also can confirm the size of the lesion: in case it is less then 15 mm in length on the sagital image then you can perform bone marrow stimulation. Symptoms. The condition typically affects just one joint, however, some children can develop OCD in several joints. When a rolling or twisting type injury occurs, part of the talus can crush or shear against another bone in the ankle joint. With this type of injury, a section of the talus surface may impact another part of the ankle joint (tibia or fibula) and injure the talus. The proportion of the patient population treated succes … These sequences were performed, and their ability to distinguish the osteochondral lesions from normal bone, cartilage, and surrounding soft tissue was assessed. [1] This may result in separation and instability of a segment of cartilage and free movement of these osteochondral fragments within the joint space. A talar dome lesion is an injury to the cartilage and underlying bone of the talus within the ankle joint. No matter how long ago your ankle injury occurred, if pain persists it’s extremely important to get a professional evaluation. See the main osteochondritis dissecans article for a general discussion on this condition, which mostly affects the knees. The cartilage can be torn, crushed or damaged and, in rare cases, a cyst can form in the cartilage. This plantair flexed CT will also give you a good idea of the location of the OCD during the surgery. This is a developmental disease that occurs in rapidly growing large breed dogs typically between 6 and 9 months of age and tends to occur more often in male dogs. “Osteo” means bone and “chondral” refers to cartilage. Approximately 50% of ankle sprains and up to 73% of ankle fractures result in some level of cartilage injury, and there are over 2 million ankle sprains alone per year. The goals of surgery are to restore the normal shape and gliding surface of the talus in order to re-establish normal mechanics and joint forces. Osteochondritis dissecans (OCD) of the talus (ankle bone) happens when repetitive trauma results in a blood supply injury to the talus and the bone either fails to develop from the cartilage your kid was born with, or the maturing bone dies and therefore softens and collapses. People with OCD report activity-related pain that develops gradually. Osteochondral lesion of talus (OLT): • Only 0.09% of all fractures and 1% of all talus fractures – Traumatic etiology – Commonly: ankle sprain • Inversion injury • 6.5 per 100 ankle sprains – Bosien et al. The talus is the bottom bone of the ankle joint. [ 46 ] Patients can have three different kinds of complaints, whether or not in combination: 1. Mild OCD: A piece of bone has begun to separate from the joint, but this piece is still firmly held in place by a covering of cartilage (dense elastic tissue that helps cushion the joint). OCD lesions are also called osteochondritis dissecans or osteochondral fractures. You and your foot and ankle orthopaedic surgeon can discuss these treatment options and decide which one is best. Ankle OCD incidence was determined for the group as a whole and by both sex and age group (divided into age groups of 2-5, 6-11, and 12-19 years). Most of the talus is covered by cartilage. In addition to standard surgical risks, additional complications may include the failure of any transplanted tissue (bone or cartilage). •Splint immobilization. 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 top of the talus is dome-shaped and is completely covered with cartilage—a tough, rubbery tissue that enables the ankle to move smoothly. The content of FootCareMD, including text, images, and graphics, is for informational purposes only. Structure and function. More involved procedures that include bone grafting or cartilage transfer may require a longer period of recovery. Keywords Ankle .Children .MRI .OCD .OLT .Osteochondritisdissecans .Osteochondrallesion .Talar dome Introduction Osteochondritis dissecans (OCD) presents as a spectrum of disease that can … incidence. The most common joints affected by osteochondritis dissecans are the knee, ankle and elbow, although it can also occur in other joints. Some patients, however, have no history of an injury to their ankle. Today, we explain what causes the condition, and what can be done to treat it. OLT can be caused by any twisting-type injury to the ankle if it is severe enough. This may be followed with gradual progression of weightbearing and physical therapy. Call or email one of our five Milwaukee podiatry clinics to schedule an appointment for your ankle pain. The content of FootCareMD, including text, images, and graphics, is for informational purposes only. They may also be called osteochondritis dessicans or osteochondral fractures. Contained lesions (lesions with an intact lateral wall) seem to have improved outcomes in comparison to uncontained lesions. Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. This condition is also known as either osteochondritis dissecans (OCD) of the talus or as a talar osteochondral lesion (OCL). Figure 11 Alternative diagnosis on CBCT compared to MRI. Often, there may be several treatment options. Your surgeon will select the best procedure to repair the OCD lesion which may involve removal of the loose bone and cartilage fragment as well as arthroscopically cleaning the joint of any inflammation. OCD most commonly affects the knee, although it can affect other joints such as the ankle or the elbow. It is also called an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). Osteochondritis can be caused by a recent or not-so-recent ankle injury. The results of non-surgical treatment of OLTs have been disappointing. The most common joints affected by osteochondritis dissecans are the knee, ankle and elbow, although it can also occur in other joints. 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. OCD. In many cases of OCD in children, the affected bone and cartilage heal on their own, especially if a child is still growing. Osteochondritis dissecans can occur in different joints, including the hip and ankle, but 75 percent of cases affect the knee. 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. Osteochondral lesions (OCLs) are focal articular injuries of the subchondral bone and the cartilage with a multifaceted cause (trauma, ligament instability, ischemic necrosis, malalignment, endocrine diseases, and others). An osteochondral ankle defect is a lesion of the talar cartilage and subchondral bone mostly caused by a single or multiple traumatic events, leading to partial or complete detachment of the fragment. After an injury such as an ankle sprain, the initial pain and swelling should decrease with appropriate attention (rest, elevation). The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. Procedures that transfer bone or cartilage to an OLT also have good outcomes. The decision on which treatment is the most appropriate is largely dependent on the age and activity level of the patient, the presence and severity of the symptoms, as well as the size and location of the lesion. Despite surgery going as well as possible, there is still a chance the pain will persist requiring additional treatment in the future. The content is not intended to substitute OLTs usually occur after an injury to the ankle, either a single traumatic injury or as a result of repeated trauma. This procedure is a single-stage procedure and as it does not require a press fit or graft contouring due to its particulate nature, it can be carried out arthroscopically. Enter This is referred to as an osteochondral defect (OCD) or osteochondral lesion of the talus (OLT). This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). A variety of terms have been used to refer to this clinical entity, including osteochondritis dissecans (OCD), osteochondral fracture and osteochondral defect. Much like other ankle sprains, osteochondritis dissecans causes swelling, pain and an inability to bear weight. When you hear the initials OCD, you probably assume we’re talking about obsessive compulsive disorder, but there’s another OCD that affects your ankles and feet. The ankle joint is the most commonly injured joint in athletes, and OCD lesions primarily are found in the ankle (Giovanni et al, 2007). The hope is to minimize symptoms and limit the risk of developing arthritis. Osteochondral lesions or osteochondritis dessicans can occur in any joint, but are most common in the knee and ankle. Lesion location, laterality, and all patient demographics were recorded. It was once believed that all OLTs progress and worsen with time. Along with the tibia and fibula (shin bones) this forms the ankle joint. Also, if an OLT is too large to heal on its own but small enough to allow for the transplantation of new tissue, surgery might be an option. Foot and ankle orthopaedic surgeons diagnose OLTs with a combination of clinical and special studies. The caring surgical podiatrists at Advanced Foot & Ankle of Wisconsin will diagnose the true source of your ankle pain so you can heal. 44,61,70 Classic teaching is that lateral OLTs are more likely due to trauma than medial lesions, with 94% of lateral lesions and 62% of medial lesions … Recovery from osteochondritis dissecans ankle surgery is likely to involve keeping your weight off the ankle for a time.
