Posterior tibial tendon injury in young patients is mainly due to trauma or overuse. Peroneal tendinopathy – Injury leading to inflammation and/or tearing in the tendons that run along the outside of … The medial facets of the talar dome articulate with the medial malleolus, and lateral facet with the lateral malleolus. However when you compare the findings with the normal patient on the left, you will detect the big accessory soleus muscle. Then continue reading. PMID: 31084491 When the capsule is thickened, it may cause impingement or synovitis, which can be seen in the image in the middle. On the image in the middle there is a deltoid ligament injury with separation of the periosteum or "periosteal stripping". stage I. injury limited to articular cartilage; MRI findings: subchondral edema; x-ray findings: none; stage II. On the right a patient who developed postoperative fibrosis after resection of a Haglund exostosis. On the axial image, the edema is localised around the insertion site of the posterior syndesmosis. Joints: screen for effusion and look at the joint capsule for thickening. On sagital images the achilles tendon should be a straight line without any fluid around it and no focal thickening. Platelet-rich plasma is significantly better than hyaluronic acid. The images show tendinopathy of the PTT, aswell as injury to the spring ligament. This probably represents a mild strain (grade 1). This patient has edema in the calcaneus as a result of a stress fracture. It has a transverse orientation and is best seen on axial images. When the posterior tibial tendon is injured, be sure to check the spring ligmanent, since they together maintain the arch of the foot on the medial side. As the foot undergoes dorsiflexion, the peroneus brevis tendon is repeatedly compressed between the peroneus longus tendon and the lateral malleolus, predisposing to tear. Background: The incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. This injury usually results from overuse, especially in runners. Series shows the case of a 25-years-old man, a sports and physically active patient, with chronic ankle pain, a lateral talus osteochondral lesion (OCL), and chronic ankle instability. Fluid around the Achilles tendon is always abnormal. In addition, the flexor retinaculum is thickened. incidence 69% of ankle fractures; 70% of ankle sprains; 10% are bilateral The patient on the left has subtle edema around the ATFL-ligament, while the ligament itself looks normal. 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. This term refers to a wide spectrum of pathologies including mild bone marrow contusion as The tendons will show relatively hyperintense signal at 55* to B0), simulating pathology like tendinopathy or partial tears. Most of the time the ATFL is injured as well. In those cases you may consider a CT-scan which can be more sensitive. The advent of new procedures for repairing cartilage in knee and ankle joints has increased the need for accurate noninvasive methods to objectively evaluate the success of repair. An osteochondral lesion is a defect in the cartilage of a joint and the bone underneath. The anterior syndesmosis is also thickened but shows low signal. • To discuss concomitant MR findings. In the foot and ankle many accessory ossicles can be seen. The amount of fluid should not exceed the volume of the tendon itself. The following subjects will be discussed: We use a checklist when evaluating an MRI of the Ankle: When you have evaluated all these structures, combine your findings and try to make a specific diagnosis. Two examples of diffuse joint effusion in the tibiotalar joint. osteochondral lesions (OCLs) of the talus. OCD is an abbreviation which can stand for either Osteochondritis Dissecans or Osteochondral Defect.Osteochondritis dissecans is used when the patient is young and the cause is not exactly known, yet most probably due to repetitive microtrauma. Posterior tibial tendon dysfunction is more common in women and in people older than 40 years of age. The pathogenesis of these disorders is different, but the clinical presentation and imaging features are not always distinctive. Thickening of the periosteum is a common finding and indicates injury of the deltoid ligament in the past. Isolated injury of the anterior syndesmosis can be seen in low grade exorotation injuries. Split tears are associated with inversion injuries, most likely due to greater force on these tendons after ligamentous injury. In this patient there is very subtle edema in the distal fibula. The PTFL courses posterior to the lateral tubercle on the posterior aspect of the talus. In A there is edema and thickening around the anterior and posterior syndesmosis (arrow), indicative of acute grade 2 injuries. You can click on the image to enlarge. On the non fatsat images however, there is obvious thickened fibrotic tissue on the anterior side. This can be challenging, because the actual tear cannot be seen, only the architectural deformation. In this case there is a lot of edema in the navicular bone. 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; Epidemiology . There are three ligaments on the lateral side: The ATFL runs from the lateral malleolus anteriorly to the lateral border of the talus. The fibers are interposed with fatty tissue, giving it a striped pattern on MR. AJR 2009; 193:687-695, Appendicitis - Pitfalls in US and CT diagnosis, Bi-RADS for Mammography and Ultrasound 2013, Coronary Artery Disease-Reporting and Data System, Contrast-enhanced MRA of peripheral vessels, Vascular Anomalies of Aorta, Pulmonary and Systemic vessels, Esophagus I: anatomy, rings, inflammation, Esophagus II: Strictures, Acute syndromes, Neoplasms and Vascular impressions, Esophagus: anatomy, rings and inflammation, Multiple Sclerosis - Diagnosis and differential diagnosis, Developmental Dysplasia of the Hip - Ultrasound, Ankle Ligaments on MRI: Appearance of Normal and Injured Ligaments. This artifact is visible on short TE images (f.e. Split tears of the peroneus longus are less common. Isolated injury of the CFL is uncommon. FIGURE 71-1 Osteochondral lesion of the talus. The talus is the bottom bone of the ankle joint. This sign presents as a fine linear band of high signal intensity which is the result of a small avulsion of cortical bone in a grade 3 full thickness tear. In addition to the standard planes, a oblique scan is sometimes included oriented perpendicular to the peroneus and tibialis posterior tendons. The extensor tendons are rarely injured. In B there is edema and thickening of the posterior syndesmosis, which is an acute grade 2 injury. Osteochondral lesions are relatively common in children and adolescents, and the incidence is increasing. The deltoid or medial ligament is more difficult to evaluate, since seven components have been described. Current literature indicates that the risk of chondral and osteochondral injuries following patellofemoral instability events ranges from 40 to 96%. When there is a break, tear, separation, or disruption of the cartilage that could be referred to as an osteochondral lesion. MR imaging is an accurate method with which to evaluate osteochondral lesions of the ankle joint, and it has become a widespread imaging modality with which to diagnose ankle disorders (1,3,5,16,17). ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. The deep layer connects the inferior border of the medial malleolus to the medial side of the talus. Accessory muscles are frequently seen around the ankle joint. cartilage injury with associated subchondral fracture but without detachment; thin sclerotic margin Another example of Achilles tendinopathy. The patient on the left has bone marrow edema in the medial malleolus. Scroll through the coronal images. Osteochondral lesions of the talus are common and difficult problems to treat. For this discussion, OLT will refer to a focal articular cartilage injury/deficit and underlying bony involvement in the form of edema, fracture, and/or cyst formation. This image shows an extreme case of insertion tendinopathy of the Achilles tendon. Radiograph of the left ankle (A) demonstrates a cortical defect with separation of an osseous fragment from the lateral talar dome (arrow). Weber B fracture (Lauge Hansen Supination Exorotation injury), Weber C fracture (Lauge Hansen Pronation Exorotation injury). More proximal, edema is seen around the membrana interossei. Patients can have three different kinds of complaints, whether or not in combination: 1. Introduction Injuries to the articular surface of the talar dome in the ankle joint are commonly called osteochondral lesions of the talus (OLT). This joint permits much of the up (dorsiflexion) and down (plantarflexion) motion of the foot and ankle. The os trigonum is present in the normal population in about 5-15%. Osteochondral Defect, Unstable. The peroneus brevis tendon is injury-prone, because it is positioned inbetween the fibula and peroneus longus tendon. This condition is also known as osteochondritis dissecans (OCD) of the talus or a talar osteochondral lesion (OCL). Bright rim sign Prognosis of these lesions depends on stability, location, and size of the lesion.Imaging has an essential role in the diagnosis, staging, and management of osteochondral lesions. When there is edema like in this case and no visible fracture line, you may consider CT. Do not mention the edema without having ruled out a fracture line on MR or CT. This patient has bone marrow edema in both the medial malleolus and the medial talus. You can enlarge the image by clicking on it. Our method applies a new navigational approach to the cross-sectional modality MR imaging. https://doi.org/10.1016/j.rcl.2008.10.001. Some components are always present, while others are variable and not always seen on a standard MR. Peroneal tendinopathy – Injury leading to inflammation and/or tearing in the tendons that run along the outside of … Much of this bone is covered with cartilage. Osteochondral lesions (OCLs) about the foot and ankle often manifest clinically as prolonged joint pain after trauma, often an ankle sprain, which is refractory to conventional, conservative therapeutic treatment. An osteochondral lesion is seen at the posterior weightbearing surface of the medial femoral condyle. Achilles tendinopathy is most likely due to a series of microtears that weaken the tendon and cause swelling of the tendon (image on the right). Background A brief anatomy of the ankle joint: Here three patients with various stages of OCD. Since they have a normal signal intensity, they are easily missed. The axial image nicely depicts the stress fracture. On the non fatsat images there is subtle thickening of the capsule, with reactive changes in the surrounding soft tissue. Thickening of the Achilles is seen with paratenonitis. It is unclear based on current literature if there is an association between the number of instability events and the prevalence and severity of chondral and osteochondral … This patient had a Weber C fracture, which is a grade 4 pronation exorotation injury in the Lauge-Hansen classification. Start your exam with fatsat images of the bones to screen for edema. Plain radiographs are useful in the initial evaluation of patients with acute or chronic complaints of ankle pain and swelling. This patient has multiple stress fractures of the calcaneus. Osteochondral defect of talus – Usually occurring from a sprained ankle, the cartilage of the anklebone becomes bruised, can crack and may lead to the formation of a cyst on the talus bone. The talar dome has no direct muscle attachments(2); during norm… The lateral ligaments also show edema and thickening. 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). This is edema due to a ligamentous avulsion injury. A study by Verhagen and colleagues found MRI has a greater sensitivity in comparison to computed tomography (CT). The Spring ligament is oriented obliquely and has a close relation with the deltoid ligament and the posterior tibial tendon. The bone right underneath the cartilage will also be injured. Here two patients with bone marrow edema. Plantar fasciitis, the most common cause of heel pain in the athlete, is a low-grade inflammation involving the plantar aponeurosis and the perifascial structures. The CFL runs from the distal fibula to the lateral side of the calcaneus and is best appreciated on coronal images. There is fibrosis along the posterior calcaneus and the posterior joint capsule. Osteochondral injury staging system for MRI attempts to grade the stability and severity of osteochondral injury and is used to plan management. The two most common injuries are tendinopathy and rupture. https://doi.org/10.1016/j.rcl.2008.10.001 Get rights and content. Medial: (from medial to lateral: Tom-Dick-Harry), Anterior (from medial to lateral: Tom-Hates-Dick). We use cookies to help provide and enhance our service and tailor content and ads. Many of these lesions are first diagnosed by plain film. RESULTS: Microscopy coil imaging at 1.5 T yielded 20% better signal-to-noise characteristics than ankle coil imaging at 3 T. High-resolution MR revealed that osteochondral junction separation, due to focal collapse of the subchondral bone, was a common feature, being present in 28 (45%) of 61 medial central osteochondral lesions. Compression of the os trigonum and surrounding soft tissues between the tibia and the calcaneus during plantar flexion can be a cause of posterior impingement. The articulation of the talar dome and the trochlear surface (tibia and fibula) supports the weight of the body. A fluid-filled break in the articular surface (arrowhead) is present, and there is fluid at the anterior interface of the fragment (arrow). This case is shown to demonstrate the great variety of ossicles and tubercles on the posterior side of the talus. Here an example of a grade 3 ATFL tear with a bright rim sign (arrow). OCD usually causes pain during and after sports. The superficial layer of the deltoid ligament is connected to the navicular bone anteriorly and the calcaneus posteriorly. Membrana interossei, which runs all the way up to the fibular head. Treatment Non-surgical or surgical treatment may be recommended for the management of osteochondral injuries of the ankle joint. There is also some joint effusion in the talocalcaneal joint. Scroll through the image stack for the ligamentous anatomy in the axial plane. Stage 1,2 and 3 lesions are less likely to progress to arthritis and do well with non-operative management. The os trigonum is present in the normal population in about 5-15%. The tibia and fibula bones sit above and to the sides of the talus, forming the ankle joint. Some examples of accessory muscles. The deltoid ligament is best evaluated in the coronal plane. It is a result of repetitive impaction of the fibrotic tissue on the bone during dorsal flexion. Three fat sat axial images of the achilles tendon. Here a normal PTFL and a grade 2 tear. Finally, when fluid flows underneath the defect, the OCD can become unstable and may result in a corpus liberum. CONCLUSION: AMIC for osteochondral talar lesions led to significant pain reduction, recovery of ankle function, and successful return to sport. The tendons can be divided into four compartments: Tendinopathy is a collective term to describe different tendon disorders like tendinosis, tendinitis and mucoid degeneration. A is showing low grade injury of the deep deltoid ligament. The patient on the right has edema in the medial talus. This part is prone to rupture because the blood flow in this area is poor, which also can impair its ability to heal. Perform the initial testing without contrast dye injection. The bone marrow edema is likely due to impaction of talus and medial malleolus secondary to inversion injury. Bones: screen on fatsat images for bone marrow edema. It is thought that it is caused by a chemical shift artifact when subcortical fatty marrow is exposed to joint fluid. In the middle and right we see two examples of cashew nut deformity, indicative of partial split rupture. It is difficult to differentiate between grade 1 and 2 injuries, because the edema will blur the normal striped pattern. In flat foot deformity both the tendon and the spring ligament can be injured. In C - the anterior syndesmosis is thickened and there probably is a focal discontinuity (arrow) and that is the reason why this was called a grade 3 injury (full thickness tear). The image on the right shows fiber discontinuity making it a full thickness or grade 3 tear. This is scar formation as a result of prior injury. Spurring as seen on a X-ray therefore can be seen in symptomatic and asymptomatic patients. The patient in the middle has thickening and architecture distortion representing a partial tear (grade 2). Sometimes the fracture line is not seen on MR. MRI is the best imaging modality, which helps to visualize the cartilage and bone lesions as well as bone edema. Ligaments: check the syndesmosis, the lateral and medial ligaments. PD). Accessory FHL or FDL are associated with tarsal tunnel syndrome. On these images we can recognize the close relationship between the deltoid ligament and the periosteum of the medial malleolus and the flexor retinaculum. Notice additional injury to the ATFL in all cases. Injuries to the articular surface of the talar dome in the ankle joint are commonly called osteochondral lesions of the talus (OLT). Cartilage is a connective tissue that covers the bones between joints. In this patient there is a full thickness tear of the anterior syndesmosis (yellow arrow). Terminology Osteochondral defect is a broad term that des... Osteochondral defects (OCD) or lesions (OCL) are focal areas of damage with articular cartilage damage and injury of the adjacent subchondral bone plate and subchondral cancellous bone. Outline. The MOCART score did not correlate with the good clinical results; the interpretation of postoperative imaging remains therefore challenging. On long TE images (like T2) this artifact does also occur but less pronounced. The bone marrow edema in these patients is due to avulsion injury on the insertion sites of the deltoid ligament. It runs from the tuberosity of the calcaneus to the heads of the metatarsal bones. Copyright © 2020 Elsevier B.V. or its licensors or contributors. They are associated with a prominent calcaneal tubercle. This was the cause of continuing impingement. In B - the anterior syndesmosis is thickened with edema, indicating partial tearing or grade 2 injury. When a small defect in the chondral plate is present, the intraarticular fluid will erode the subchondral bone, which will result in bone marrow edema. In C there is scar tissue as a result of previous injury, which again can be a cause of posterior impingement. The most common ossicle is the os trigonum, which is a prominent unfused apophysis of the lateral tubercle of the talus. B and C clearly show disruption of fibers, so these are grade 3 injuries. At the insertion on the medial malleolus, it blends with the periosteum of the medial malleolus and the flexor retinaculum. The left image shows a normal fluid accumulation in the tibiotalar joint, talocalcaneal joint en retrocalcaneal bursa. This ligament serves as a hammock for the talus. Other terms that refer to the same general process are osteochondral defects (OCD), osteochondritis dissecans, and transchondral fracture. The posterior tibial tendon is the most commonly injured tendon. Most tendons in the ankle joint have a tenosynovial layer. Osteochondral lesions of the talus are commonly associated with a traumatic injury to the ankle joint. 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. The Achilles tendon is the largest and strongest tendon in the human body. This means that when the CFL or the PTFL are injured, it is very likely that the ATFL is injured aswell. The CFL passes two joints, the talocrural joint and the talocalcaneal joint. Radiographs showed a suspicious area on the lateral talar dome. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome. This patient has an unfused prominent lateral tubercle with a fibrous connection to the talus, therefore it is a partly fused os trigonum. By continuing you agree to the use of cookies. This is especially seen in ballet dancers. This can be a cause of Achilles tendinopathy. Here we see three patients with ATFL injury. The effusion can run alongside the flexor hallucis longus tendon (FHL), since this tendon sheath is continuous with the joint. Edema is present in the bed of the defect (asterisk). Noncontrast MR imaging is the standard of care imaging modality for diagnosing and classifying osteochondral lesions… In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Capsular thickenig and soft tissue abnormalities are usually better seen on non-fatsat images. by Kiley D. Perrich et al. Notice that there is also a grade 2 tear of the ATFL. Here another patient with an os trigonum. Here an example of an os trigonum with rather subtle edema. This patient had anterior ankle pain due to impingement by the thickened capsule. The patient on the right has a full thickness tear (grade 3). They are usually asymptomatic, but can be a cause of impingement in specific patient groups (dancers, athletes). • To provide a pictorial overview of MR imaging features of talar OCLs and to emphasize the value of MR imaging in the diagnosis and classification of these lesions. Usually this is best appreciated on fatsat images. On the fatsat images, you may think that there is only some edema in the subcutaneous fatty tissue. Background:Osteochondral lesions of the talus (OCLTs) secondary to ankle fractures have previously been reported in the literature. Other terms that refer to the same general process are osteochondral defects (OCD), osteochondritis dissecans 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. Isolated injury is very rare. Small tears or subtle tendinopathy are better visualized on these views. The articular cartilage imaging group of the International Cartilage Repair Society has issued detailed recommendations with r… On the image on the right there is thickening of the deltoid ligament with a low signal intensity as a result of chronic injury. The term Stieda process is used, when the lateral tubercle is very prominent. Bone marrow edema is only an indication that there is something abnormal in the bone or connected structures. In this case there is fibrous thickening of the capsule (arrow). When the patient is treated, the edema will vanish, but the spurring may still be present. Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. This is the most commonly injured ligament of the ankle and it is also the first to be injured on the lateral side. This process can evolve into cyst formation. MR can show edema around the insertion of the plantar fascia on the calcaneus and spurring. Copyright © 2008 Elsevier Inc. All rights reserved. A small amount of fluid around the tendon therefore can be normal. 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. Caudally, it is connected to the Spring ligament, which is the superomedial part of the calcaneonavicular ligament. No fracture line is visible. It results in pain and swelling on the medial aspect of the ankle and an acquired flatfoot deformity. Note that the periosteum and flexor retinaculum are also thickened. The peroneus longus tendon migrates forward into the peroneus brevis tendon tear, thereby preventing healing (figure). In the foot and ankle many accessory ossicles can be seen. 1–3 Two common lesions are notable on the talus. In this patient there is only a small effusion in the ankle joint. Rupture of the Achilles tendon usually occurs in the part of the tendon situated within 6 centimeters of the insertion to the calcaneus. Patients typically present with chronic ankle pain and swelling, and some have mechanical symptoms. MRI is the best imaging modality which helps to visualize the cartilage and the bone lesions as well as bone edema. Tendinopathy is seen as abnormal swelling of the tendon, but you have to realize, that the normal posterior tibial tendon can measure twice the size of the flexor digitorum tendon. Both patients have had an eversion injury, with stretching of the deltoid ligament. The orientation of the tendons along the medial and lateral malleolus can cause the 'magic angle artifact' to occur. This can also lead to posterior impingement. Standard axial, coronal and sagittal planes are used in the ankle both on 1.5T and in 3T. Too much fluid is indicative of bursitis. Once you have studied the bones, scan the joints for effusion. A transverse diameter of 8 mm is the cut off. These images show injury to the deep deltoid ligament. The achilles tendon does not have a tenosynovial layer but a paratenon. In this article a systematic approach is presented on how to describe a standard MRI of the ankle. On the axial image more unfused prominent tubercles on both the medial and lateral side of the lateral tubercle are seen. This is an example of posterior impingement due to a symptomatic os trigonum. Stress fractures are easy to miss on MR alone and this could lead to a wrong diagnosis like for instance osteomyelitis. This term covers a wide spectrum of pathologies including (sub)chondral contusion, osteochondritis dissecans, osteochondral fracture and osteoarthritis resulting from longstanding disease. Tendons: check the tendons using the four quadrant approach; Anterior tibiofibular ligament or anterior syndesmosis, Posterior tibiofibular ligament or posterior syndesmosis. They typically are associated with a history of trauma; however, nontraumatic etiologies have been described. Staging of Osteochondral Lesions of the Talus: MRI and Cone Beam CT Magdalena Posadzy*, Julie Desimpel† and Filip Vanhoenacker‡ Osteochondral lesions (OCL) of the talus involve both articular cartilage and subchondral bone of the talar dome. There is also a fracture of the malleolus tertius (blue arrow). When the fracture is not seen on the T2W fatsat-images, look at the non-fatsat T2W or the T1W- images for a hypointense fracture line. Stress fractures of the calcaneus are a frequently unrecognized source of heel pain. First look at the images. The patient on the right has a hypertrophic plantaris muscle. When it is injured, there has to be injury to the other lateral ligaments. Acute injury presents as edema and thickening, while an old injury presents with thickening and low signal intensity due to scar formation. Here another example of thickening of the capsule. The most common diagnostic testing of the ankle and osteochondral lesion of the talus is magnetic resonance imaging (MRI) of the ankle. 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. Noncontrast MR imaging is the standard of care imaging modality for diagnosing and classifying osteochondral lesions, but equivocal or difficult lesions can be assessed more specifically with direct MR arthrography or in conjunction with multidetector CT. Once an OCL has been identified, the imager should make every effort to determine whether it is stable or potentially unstable. The Haglund syndrome consists of the triad of: This image shows fibrotic tissue anterior to the Achilles tendon (yellow arrow) after resection of a Haglund exostosis. Non-surgical: Osteochondral lesions of the ankle can be treated with injections of Platelet-rich plasma and hyaluronic acid, which results in a decrease in pain scores and an increase in function for at least 6 months. The syndesmosis, the edema is seen in the Lauge-Hansen classification small tear is initiated, it is common.
