Several mechanisms have been proposed for spur formation along the anterior margin of the joint. ; Source: Current Orthopaedic Practice, Volume 30,Number 1, January/February 2019, pp. The role of MRI in detecting anteromedial impingement has not yet been established [45] (Fig. Direct MR arthrography with intraarticular instillation of contrast agent has been shown to be highly sensitive (97%) and specific (100%) for assessing the anterolateral recess [25]. Clinical presentation Os subfibulare are usually asymptomatic although they may eventually cause painful syndromes or degenerative change in response to overuse and trauma. Malicky ES, Crary JL, Houghton MJ et al. In comparison, anterior osteophyte formation has been attributed to joint abnormalities related to hyperdorsiflexion, microtrauma, ankle instability, and recurrent supination [38, 39]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. MRI showed increased signal in the posteromedial capsule in four of nine subacute cases, increased signal in the posterior tibiotalar ligament in nine of nine cases, displacement of the PTT and flexor digitorum longus tendons in seven cases, and disruption of the posterior tibiotalar ligament fibers in four cases [20]. Epidemiology It is usually a unilateral phenomenon. Entrapment and thickening of the calcaneofibular ligament are also seen (Fig. Patients with anteromedial impingement often present with chronic anteromedial pain that is exacerbated by dorsiflexion.

On physical examination, there is focal anteromedial ankle tenderness and swelling with limited dorsiflexion and supination [4, 46]. author = "Kaplan, {Jonathan R.M.} The most common symptoms include pain and tenderness along the posterior ankle that is exacerbated on plantar flexion or dorsiflexion [6, 55]. Surgery for anterolateral impingement is reserved for patients not responding to conservative treatment such as physiotherapy or nonsteroidal antiinflammatory drugs (NSAIDs). There are several causes of lateral hindfoot impingement including PTT dysfunction [67, 68], healed intraarticular calcaneal fractures [69], neuropathic arthropathy [70], and inflammatory arthritides [71]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies.

Surgical Technique for Management of Severe Calcaneofibular Impingement: Case Series:. On ultrasound, hypoechoic nodular posteromedial soft-tissue thickening may be seen deep to the PTT, between the medial malleolus and talus. Peroneal tendon subluxation (Fig. Furthermore, ultrasound can facilitate imaging-guided therapeutic injection of the synovial lesion [20]. MRI often is necessary to rule out other causes of ankle pain. Similar to other types of ankle impingement, Doppler evaluation does not show increased flow within the abnormal soft tissues. Furthermore, mild posteromedial synovitis was present in two control subjects [20]. Pathophysiology and clinical features Anteromedial impingement is a relatively rare ankle impingement [45]. Ultrasound is helpful in guiding therapeutic injection of the posteromedial synovial mass in select patients with no associated osteochondral abnormality or joint instability [20]. Radiographs enable evaluation of the spurs and the tibiotalar joint space, both of which are important for diagnosis and preoperative planning (Fig. MRI often is necessary to rule out other causes of ankle pain.

Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Welcome to MyMichigan Health. Femoroacetabular impingement is an intra-articular or internal form of impingement, where structural changes combined with dynamic factors as repetitive abnormal contact of the acetabulum and the femoral head-neck junction lead to mechanical stress and shear forces on the labrum and chondral surfaces and subsequent damage 1-4. foot and ankle surgery; 1: 90 (1070): 20160735. Posterior ankle impingement (PAI) syndrome is one of the impingement syndromes involving the ankle. The extent of arthro desis should be limited to minimize the stress transfer to proximal and distal joints [72]. N1 - Publisher Copyright: Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. In this review, we describe the pathophysiology, clinical presentation, and imaging features of ankle impingement syndromes and extraarticular impingement syndromes with a focus on MRI findings. Check for errors and try again. Ultrasound has been shown to correlate well with arthroscopic findings in its ability to detect soft-tissue abnormalities including a synovial mass or capsular nodularity in the anterolateral gutter [19]. Impingement is a clinical syndrome of chronic pain and restricted range of movement caused by compression of abnormal bone or soft tissue within the ankle joint. This can include talocalcaneal, calcaneofibular (subfibular) or combined talocalcaneal-subfibular impingements. Regardless of the initial cause of flatfoot, patients with rigid flatfoot deformity experience decreased range of motion at the midfoot and hindfoot and decreased ankle dorsiflexion [72]. Impingement can be associated with a prior single traumatic event or repetitive microtrauma, often in an adolescent with anatomical predisposition. T2 - Current concepts, imaging findings and management strategies. CT is more sensitive than radiography for identifying cystic and sclerotic changes [9].

N2 - Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. MRI; Marrow edema is uncommonly seen with anterior ankle impingement [29, 44]. Interobserver agreement and accuracy, sensitivity, and specificity in the detection of fibular periostitis, peroneal . However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures This accessory, or distal, fascicle is separated from the anteroinferior tibiofibular ligament by a fibrofatty septum (Fig. or neuropathic or inflammatory arthritidies. 3 CONCLUSION. The diagnosis of anterior impingement is usually clinical, based on anterior ankle pain with limited and painful dorsiflexion [31]. ;Sheth, Pooja A trial of nonoperative management should be exhausted prior to open or arthroscopic procedures being considered. Posteromedial abnormalities were present in all patients with a clinical diagnosis of posteromedial impingement, but posterior and posterolateral synovitis were also seen in these patients [20]. Arthroscopy and open surgery to remove spurs or soft-tissue abnormalities are effective in patients with no underlying tibiotalar articular disease [3, 34, 36, 40, 41]. Conventional weight-bearing ankle radiographs are useful to assess the plantar arch and hindfoot valgus. 3).

Ligamentous and capsular tearing and the resultant microinstability and hemorrhage after an ankle sprain may lead to reactive synovial hyperplasia and scarring in the anterolateral gutter [2] (Fig. MRI is useful in confirming the diagnosis, evaluating patients with an uncertain clinical diagnosis, and planning surgery. Pain can also be caused by flexor hallucis longus (FHL) tenosynovitis [53] and soft-tissue impingement. CT may be helpful for further characterizing the location and size of the spurs but is rarely indicated [36] (Fig. Ankle impingement, typically secondary to an ankle sprain, is classified according to its anatomic relationship to the tibiotalar joint as anterolateral [2], anterior [3], anteromedial [4], posteromedial [5], or posterior [6] impingement. Os subfibulare is an accessory ossicle that lies at the tip of the lateral malleolus of the ankle and is rarely reported 1. 7A, 7B) may be noted on axial, sagittal, or coronal MRI. The addition of Doppler assessment has not been shown to be helpful [19]. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. 4A, 4B). Compression causing subsequent hypertrophic changes and fibrosis of the posteromedial tibiotalar capsule and posterior deltoid fibersspecifically, those of the posterior tibiotalar ligament between the talus and medial malleolusis suggested as the inciting event for posteromedial impingement [5]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Additionally, MRI is valuable in the detection of extraarticular, lateral hindfoot impingements in patients with hindfoot valgus deformity. CT; In most patients, ultrasound will show hypoechoic, nodular capsular thickening localized to the lateral aspect of the lateral talar process or the os trigonum.

However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. For patients unable to undergo an MRI examination, CT arthrography may be useful. Physical therapy and orthotics relieve stress and pain in the ankle. Conventional MRI may play a role in excluding other abnormalities contributing to a patient's symptoms, such as talar osteochondral injuries, but may not be sensitive in detecting subtle capsular changes. Methods:: Patients with posterior tibial tendonitis were retrospectively searched and reviewed. Role of imaging and imaging featuresIn most cases, conventional, preferably weight-bearing, radiography is the imaging study of choice because anterior impingement is typically related to osseous abnormalities [3, 42]. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies.

Therefore, detection of impingement with MRI at an early stage may be beneficial [10, 74]. These patients include those with isolated posteromedial synovitis and no associated chondral injury or ligament instability. Some of these abnormalities may coexist with anterolateral impingement and may lead to persistent pain despite surgical resection of the tissues causing impingement. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. This can include talocalcaneal, calcaneofibular (subfibular)or combined talocalcaneal-subfibular impingements. 1 to maintaining your privacy and will not share your personal information without 3. Talocalcaneal impingement typically occurs before subfibular or combined talocalcanealsubfibular impingements [9, 10]. What causes Subfibular impingement?

An additional imaging feature, seen more commonly in patients with clinical anterolateral impingement, includes the absence of the recess between the anterolateral soft tissues and the anterior surface of the fibula despite adequate joint distention with contrast material [25]. In general, the diagnosis of ankle impingement is clinical, with supporting information provided by radiographs and more advanced imaging (CT, MRI and ultrasound), 3 - 6 which can help further elucidate the anatomic mechanism of impingement, localize pathology to guide diagnostic and therapeutic injections and assist with pre-surgical planning. However, in the setting of a prior ankle sprain, posterolateral ankle laxity leads to anterior extrusion of the talar dome with dorsiflexion, increased pressure at the site of contact, and subsequent synovial hypertrophy and impingement between the anterolateral talus and the accessory anteroinferior tibiofibular ligament [12]. Talocalcaneal and subfibular impingement in symptomatic flatfoot in adults. The main differential diagnosis for postero medial ankle pain includes PTT abnormalities. The Achilles tendon may show contracture and tightness [72]. / Kaplan, Jonathan R.M. Kaplan, Amiethab Aiyer, Duc M. Nguyen, Ettore Vulcano, Leonard T.

Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. American journal of roentgenology. The mechanism is not well understood but is likely a rare complication of a supination (inversion) injury [4, 46] rather than a pronation (eversion) injury as initially hypothesized [45]. Most patients with posterior impingement respond to conservative management including physiotherapy. Alternatively, there may be subluxation of the subtalar joint resulting in impingement between the calcaneum and the fibula 4. Extra-articular calcaneofibular impingement (EA-CFI), Extra-articular talocalcaneal impingement (EA-TCI), Extraarticular lateral hindfoot impingement syndrome, Extra-articular lateral hindfoot impingement syndrome (ELHIS), additionally, removal of any subfibular or superolateral calcaneal bone causing impingement. Several normal osseous and soft-tissue anatomic variants predispose individuals to posterior impingement including a prominent os trigonum, a prominent lateral talar process (Stieda process), a shelflike superior prominence of the calcaneal tuberosity, and a posterior intermalleolar ligament [49, 52]. 4. Healed intra-articular calcaneal fractures, neuropathic arthropathy, and inflammatory arthritides may also play a causative role.

Campbell, 2019 MENU Browse Resources Authors Librarians Editors Societies Reviewers Advanced Search IN THIS JOURNAL Journal Home Browse Journal Current Issue OnlineFirst ;Jose, Jean In cases of sinus tarsi narrowing, calcaneofibular impingement is unlikely to occur without sinus tarsi impingement. The frequency of subfibular impingement was also statistically higher in the group with periostitis than in the group without it (p < .001). It is of paramount importance, however, to remember that MRI features supportive of impingement may be present in asymptomatic individuals and that accurate diagnosis requires careful correlation of imaging features with the clinical picture. It is thought to represent a normal variant and may be identified in 2197% of ankles [12, 1416]. You may be trying to access this site from a secured browser on the server. Unilateral Sacroiliitis: Differential Diagnosis Between Infectious Sacroiliitis and Spondyloarthritis Based on MRI Findings, Clinical Observations. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is typically associated with pes planovalgus resulting from posterior tibial tendon dysfunction or calcaneal fracture malunion.. How do you treat ankle impingement? Is there an ICD 10 for left shoulder impingement syndrome? Syed Ehtasham Junaid, Anil Haldar, Raul Colta, Karan Malhotra, Kar Ho Brian Lee, Matthew Welck, Asif Saifuddin. Management focuses on limitation of symptom-provoking activity, such as correction of overpronation in ballet dancers, as well as physiotherapy [31]. Pathophysiology and clinical features Anterior ankle impingement syndrome is a common cause of chronic ankle pain, especially in ballet dancers and soccer players [31, 32]. 4: Results: Twenty-eight cases (37%) of lateral hindfoot impingement were identified, including six talocalcaneal, eight subfibular, and 14 talocalcaneal-subfibular impingements. ;Vulcano, Ettore 2. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. The main role of ultrasound is to assist with therapeutic injection of the synchondrosis [56]. 5. MRI features of lateral hindfoot impingement are more commonly seen in patients with advanced PTT tears and with greater MR hindfoot valgus angle [10]. 10A, 10B, 10C and 11A, 11B). All rights reserved. Furthermore, abrasion of the anterolateral talar dome articular surface and secondary chondral injury may develop [15]. Glenoid Dysplasia: Incidence and Association with Posterior Labral Tears as Evaluated on MRI, Original Research. Although some patients present after an acute injury such as avulsion of the posterior talofibular ligament, disruption of the synchondrosis, or a talar fracture, most patients report insidious development of symptoms related to repetitive athletic activity that requires plantar flexion [6]. The efficacy of conventional nonarthrographic MRI to detect anterolateral gutter soft-tissue abnormalities remains controversial, with a wide range of sensitivities (39100%) and specificities (50100%) [2123], and has been shown to be accurate in detecting only substantial joint effusions [24]. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. The ossicle itself may fracture. Conventional arthrography may confirm disruption at the synchondrosis, evident by contrast material collecting within the synchondrosis, and is an excellent tool for performing a diagnostic or therapeutic injection.

Advanced Radiology Services hires the nation's best and brightest board-certified radiologists. Delaminated Tears of the Rotator Cuff: Prevalence, Characteristics, and Diagnostic Accuracy Using Indirect MR Arthrography, Original Report. A superimposed rotational mechanism and repeated microtrauma lead to anteromedial capsular thickening and synovitis in the region of the anterior tibiotalar ligament of the deltoid complex [4]. As in the assessment of patients with anterolateral impingement, the addition of Doppler ultrasound does not show increased flow within the abnormal soft tissue in patients with posteromedial impingement [19, 20]. MRI may be useful in examining patients in whom coexistent abnormalities are suspected clinically [29]. The accessory anteroinferior tibiofibular ligament may normally contact the anterolateral corner of the talus. 10A, 10B, 10C). Administration of IV gadolinium may improve detection of small focal areas of synovitis surrounding the posterior ligaments [60].

Patients with anterolateral impingement present with chronic ankle pain, swelling along the anterolateral aspect of the ankle, and limited dorsiflexion. Ankle impingement syndromes are defined as pathologic conditions resulting in chronic, painful restriction to movement at the tibiotalar articulation secondary to soft-tissue or osseous abnormalities [1]. The other authors have no disclosures. On physical examination, there is posterior ankle tenderness and occasionally there may be palpable soft-tissue thickening anterior to, but not involving, the Achilles tendon [6]. Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. Some error has occurred while processing your request. A clinical sign that is helpful in differentiating posteromedial impingement and PTT abnormalities is posteromedial tenderness on inversion with the ankle in plantar flexion, which is seen in patients with posteromedial impingement and not in those with PTT abnormalities [5]. MRI often is necessary to rule out other causes of ankle pain. Subjects had documented flatfoot deformity, posterior tibial tenderness, weight . Ankle impingement syndromes: an imaging review. Posterior impingement, also termed os trigonum syndrome, typically occurs due to a large os trigonum or Stieda process . These include talonavicular arthrodesis, double arthrodesis at Chopart joints, a subtalar arthrodesis, and a triple arthrodesis.

Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. Production or aggravation of pain during this maneuver, or so-called positive impingement sign, has been shown to be highly sensitive and specific (94.8% and 88%, respectively) for identifying anterolateral impingement [17]. The objective of this article is to review the pathophysiology and clinical presentation of impingement syndromes at the ankle joint (anterolateral, anterior, anteromedial, posteromedial, and posterior) and the role of MRI in evaluating impingement at the ankle joint and at extraarticular locations, lateral to the ankle joint (talocalcaneal and calcaneofibular). Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. In patients with anterolateral impingement, indirect MR arthrography did not offer additional information compared with conventional MRI [29]. Anterolateral Impingement (Ankle) 6 min. Imaging features of subfibular impingement often include extensive lateral soft-tissue thickening between the fibula and the calcaneus (Fig. It usually occurs following a sprain injury or repetitive microtrauma causing haemorrhage, synovial hyperplasia, and abnormal soft tissue interposition within the joint. However, in recalcitrant cases unresponsive to conservative treatment, there are several surgical procedures described for the management of these deforming forces. MRI often is necessary to rule out other causes of ankle pain, and advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-Tissue thickening between the Fibula and the calcaneu. Associated with severe hindfoot deformity, subfibular. Please try after some time. 15. It remains unclear whether this is primarily due to bony or soft-tissue impingement. Jay M. Levin, James K. DeOrio. 6A, 6B). Surgical correction of osseous lateral hindfoot impingement related to hindfoot valgus is increasingly being performed [7]. Intraarticular contrast instillation in conjunction with CT or MRI may be more accurate for detecting capsular abnormalities and osseous spurs [4]. subfibular impingement, Affiliations: In patients with advanced synovitis, the synovial tissue may become molded to the triangular shape of the anterolateral gutter. Pain can be caused by disruption of the cartilaginous synchondrosis between the os trigonum and the lateral talar tubercle due to repetitive microtrauma and chronic inflammation. The goal of conservative treatment early in the course of the disease is to prevent further disability and progressive deformity. Data is temporarily unavailable. The awareness of hindfoot malalignment on non-weight-bearing ankle MRI. Lateral talocalcaneal and subfibular impingements were defined as signal and morphologic alterations or direct contact at the opposing surfaces of the lateral talus and calcaneus and at the fibula and calcaneus, respectively. This condition is most commonly seen in ballet dancers [51] and soccer players [39]. 1A, 1B). Address correspondence to A. Donovan ([emailprotected]). 5A, 5B). These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. Role of MRI and imaging featuresThe role of MRI in evaluating anterolateral impingement is to exclude abnormalities other than soft-tissue impingement and to assess patients with an uncertain clinical diagnosis. No Reference information available - sign in for access. presence of subfibular impingement, and hindfoot valgus angle measurements. 2 Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment However, there is no associated ligamentous ankle instability. However, the severity of symptoms is not associated with the presence or size of either of these two structures [6]. Osseous correction of hindfoot deformity is required and consists of calcaneal osteotomy, either at the body (medial calcaneal displacement osteotomy) or at the anterior calcaneus (lateral column lengthening). modify the keyword list to augment your search. MRI can aid in the management of posteromedial impingement by excluding significant concomitant injuries and by identifying patients who may benefit from ultrasoundguided therapeutic injection. Because anterolateral impingement is a soft-tissue abnormality, conventional radiography has limited utility apart from excluding osseous abnormalities. Extra-articular lateral hindfoot impingement syndrome is a non-traumatic cause of ankle impingement. title = "Subfibular impingement: Current concepts, imaging findings and management strategies". Operative treatment is reserved for patients that fail non-operative treatment. Bilateral posterior ankle impingement syndrome has been described but is rare 5 . View Record in Scopus Google Scholar. Together they form a unique fingerprint. The predominant abnormality detected on MRI is spur formation along the anterior tibial rim, medial lateral malleolus, or talar neck and is often accompanied by synovitis and soft-tissue thickening in the anterior recess (Fig. Hindfoot valgus (often defined as a tibiocalcaneal angle >11) with one or both of the following 5: Treatment may be non-operative or operative.

Journal of Bone and Joint Surgery (Am) 2002 November 84-A: 2005-2009. . MRI may be advantageous compared with ultrasound in differentiating between anterolateral impingement and other potential osseous and intraarticular causes for persistent ankle pain after an ankle sprain such as marrow contusions, chondral defects, osteochondral talar lesions, intraarticular bodies, and sinus tarsi syndrome. CT facilitates accurate assessment of osseous changes between the os trigonum and talus, such as fragmentation of the os and pressure-related erosions along the talus [49]. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. Associated findings include thickening of the anterior talofibular ligament. Both conventional MRI and ultrasound are useful for detecting posteromedial impingement [20, 48]. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. In patients unresponsive to conservative therapy, arthroscopic resection of the os trigonum and any associated soft-tissue abnormality can also result in symptom relief and functional improvement [6, 55]. American Journal of Radiology, September 2010, Vol. Introduction Pain localized to the lateral subtalar region is often clinically felt to represent either subtalar joint degeneration or sinus tarsi syndrome. 2: Osseous outgrowths at the anterior ankle joint, which are at times asymptomatic, represent a major pathologic component of this impingement syndrome, but soft-tissue impingement due to hypertrophied synovium also occurs [33] (Fig. Associated injuries including articular cartilage and ligamentous tears need to be assessed and potentially may need to be repaired during surgery. MRI often is necessary to rule out other causes of ankle pain. Soft-tissue abnormalities at the posterior ankle such as posterior capsular thickening, ligament disruption, FHL tenosynovitis, and soft-tissue edema and synovitis can also be well depicted by MRI [49, 50, 60] (Figs. MRI has been used to evaluate both the subacute stage (i.e., within 4 weeks of the participating injury) and the chronic stage (i.e., 1452 weeks after injury) of posteromedial impingement [20, 48] (Fig. Conservative management is usually successful in most patients with anterior ankle impingement syndrome. 1A, 1B ). Clinical presentation ;Aiyer, Amiethab The radiologist must recognize, however, that MRI features supportive of impingement may not necessarily be the cause of the patient's pain and that accurate diagnosis requires careful correlation with the clinical picture and, if necessary, dynamic ultrasound for confirmation.

Ultrasound-guided therapeutic injections can provide symptom relief in appropriately selected patients. Patients usually present after the development of significant soft-tissue abnormality such as synovial thickening along the posterior capsule or thickening of the posterior intermalleolar or talofibular ligaments [52, 54]. Level of Evidence: Level V.". Patients usually present with posteromedial point tenderness and pain between the medial wall of the talus and the posterior margin of the medial malleolus [5, 20]. Pathology Etiology Glenohumeral Joint, Wrist and Ankle Plica. Early detection of impingement using MRI may be beneficial for successful surgical results [9, 10]. (2009) AJR. 7 min. Advanced imaging findings are related to abutment between the fibula and calcaneus and include subcortical marrow edema, cystic changes, sclerosis, and the presence of soft-tissue entrapment or extensive soft-tissue thickening between the fibula and the calcaneus. Similar to conventional MRI, this technique is limited by a lack of joint fluid [29].
