We also thank James Babb for statistical analysis. At the calcaneus, the marrow findings were mainly seen at the junction of the calcaneal tuberosity with the anterior process of the calcaneus. Fig. MeSH 1). Clipboard, Search History, and several other advanced features are temporarily unavailable. 2020 Jan 15;34(1):46-52. doi: 10.7507/1002-1892.201905087. Both the consensus and the two independent interpretations showed that the frequency of peroneal tendon subluxation-dislocation was significantly greater in the group with periostitis (62.9%, 65.7%, and 85.7%) than in the group without periostitis (5.7%, 0%, and 14.3%) (p < .001). Most patients had mild (n = 31, 41%) or moderate (n = 25, 33%) hindfoot valgus (Fig. Additionally, the mean valgus measurements by the two readers were significantly higher for patients with peroneal tendon subluxation-dislocation (reader 1, 35.4; reader 2, 34.5) than those without it (reader 1, 27.2; reader 2, 25.7) (both readers, p < .001). The most common ankle injury is a sprain of the ATFL, which typically results from a plantar flexion/inversion mechanism,12,13 and impingement is an uncommon sequela (occurring in approximately 2% of cases).

[13] showed that valgus alignment measurement on MRI by means of the medial calcaneal contour was the most accurate method and had sensitivity and specificity of 86% and 75% with radiographic measurements as the reference standard. Extraarticular lateral hindfoot impingement is associated with advanced posterior tibial tendon tears and increased MRI hindfoot valgus angle. Impingement was seen in 32% (n = 20/62) of grade I, 50% (n = 3/6) of grade II, and 71% (n = 5/7) of grade III posterior tibial tendon tears. The blinded readers had substantial or almost perfect agreement on all imaging interpretations (concordance rate, 82.995.7%; = 0.660.91). In summary, the MRI features of lateral hindfoot impingement including osseous and soft-tissue abnormalities were more commonly seen in patients with advanced posterior tibial tendon tears and with a greater MRI hindfoot valgus angle. This may result in retromalleolar pain, lateral ankle instability, or popping and snapping sensations along the distal fibula [6]. Alternatively, further evaluation with ultrasound would be an additional cost-effective method of detecting peroneal tendon subluxation-dislocation, providing the advantage of the real-time dynamic properties of ultrasound and its utility for evaluating the integrity of the peroneal tendons and the SPR [23]. Displaced Flap Tears of the Triangular Fibrocartilage Complex: Frequency, Flap Location, and the Comma Sign on Wrist MRI, Review. Anteroposterior radiograph shows periostitis at level of insertion of superior peroneal retinaculum (SPR) (arrowheads). MRI features of talocalcaneal impingement (n = 20) included marrow edema (n = 20, 100%) or cystic changes (n = 19, 95%) (Figs. All rights reserved. Tearing of the superior peroneal retinaculum is a known cause of peroneal tendon subluxation-dislocation. Peroneal tendon displacement, previously not described in association with posterior tibial tendon dysfunction, may also be encountered with advanced hindfoot valgus and lateral impingement. WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Foot Ankle Int. 3). In addition, the presurgical status of the peroneal tendons is important because these tendons may be involved in several surgical procedures related to correction of a flatfoot deformity. Clin Orthop Relat Res. Among the 220 patients whose cases were ultimately reviewed, 201 underwent a standard three-view examination and 19 underwent a standard two-view examination.

Third, access to patients' clinical history and surgical correlation was restricted, and the MRI criteria for impingement were established in the absence of clinical correlation. CLINICAL IMPACT. A, Drawings across coronal (A) and axial (B) planes show direct fibular and calcaneal contact due to calcaneal valgus with secondary stripping of superior peroneal retinaculum (open arrows) at its fibular attachment, distal fibular tip periostitis (solid arrow), and dislocation of peroneal tendons (arrowhead, B). MRI studies were evaluated by consensus by two musculoskeletal radiologists with 22 and 1 years of experience, respectively. In this case, a tricortical iliac crest autograft was cut to fill this defect. Acute traumatic injuries involving ankle dorsiflexion with inversion and forceful contractions of the peroneal musculature can avulse or strip the SPR at its fibular attachment, allowing the peroneal tendons to sublux or fully dislocate out of the retromalleolar groove [5]. This case depicts this procedure applied to a 42-year-old man who had undergone nonoperative treatment for a calcaneal fracture 4 years prior. Chronic undiagnosed peroneal tendon subluxation-dislocation can be a persistent cause of lateral ankle pain, leading to further degeneration and the possibility of complete peroneal tendon tears. PMC Lateral hindfoot impingement is, The clinical test for anterolateral ankle impingement is the impingement test or Molloy-Bendall test. 6A Radiographic findings in distal fibular periostitis. Among the 24 patients with fibular periostitis and MRI evidence of impingement, 18 (75.0%) also had peroneal tendon subluxation-dislocation (Figs. 1. The bone spurs can either form on the end of the shin bone (the tibia), on top of the ankle bone (the talus), or on both. The patient sample with hindfoot valgus was subdivided into two groups: a case group that included patients with radiographic fibular tip periostitis and a control group of age- and sex-matched individuals with no radiographic evidence of fibular tip periostitis. Philidelphia, JB Lippincott: 231-254, 1996. In one patient, there was remodeling of the calcaneus and fibula with the formation of a neofacet (Fig. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. The most common ankle injury is a sprain of the ATFL, which typically results from a plantar flexion/inversion mechanism, A common source of chronic ankle pain among athletes is anterior ankle impingement. The blinded readers had substantial or almost perfect agreement on all imaging interpretations (concordance rate, 82.9-95.7%; = 0.66-0.91). This association was first postulated by Donovan and Rosenberg [10] in 2009, but to our knowledge there have been no additional discussions in the literature surrounding peroneal tendon dislocation in patients with lateral subfibular impingement syndrome. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. C, Axial fat-suppressed proton-density MR image shows lateral subluxation of peroneus longus tendon at level of retromalleolar groove (arrow) and fibular periostitis (arrowhead). It is connected to the talus by a fibrous band. Thirteen patients were excluded from the initial sample, leaving a total of 207 patients for inclusion in final enrollment (Fig. Please see the Editorial Comment by Lauren Ladd discussing this article. Copyright 2013-2020, American Roentgen Ray Society, ARRS, All Rights Reserved. Thus, the presence of fibular tip periostitis may be the first sign that further investigation to assess the integrity of the peroneal tendons may be warranted before surgery. 4A, 4B, 4C, 4D). Oblique radiograph shows diffuse smooth periostitis (arrows) along distal fibular diaphysis not correlating with SPR attachment site and presumed on subsequent MRI (not shown) to be secondary to chronic venous insufficiency. The site is secure. MRI studies can help identify the size of peroneal tendon tear and identify concomitant injuries to nearby structures. Interobserver agreement and accuracy, sensitivity, and specificity in the detection of fibular periostitis, peroneal tendon subluxation-dislocation, and subfibular impingement were calculated, and Fischer exact, Mann-Whitney, kappa coefficient, and intraclass correlation tests were performed. Fig. Fig. However, SPR abnormalities and peroneal tendon subluxation-dislocation are typically radiographically occult, and the clinical symptoms can often be misdiagnosed as a lateral ankle ligament sprain [5, 6]. The keyword search yielded the records of 220 consecutively enrolled adult patients with hindfoot valgus and both ankle radiographs and MRI examinations. BACKGROUND. Statistical computations were performed using SAS version 9.0 (SAS Institute). To the best of our knowledge, the MRI appearance of lateral hindfoot impingement has not been reported. RESULTS. Correction of hindfoot valgus, however, may not relieve lateral ankle pain if the peroneal tendon abnormality is not addressed. 2012 Sep 5;94(17):1584-94. doi: 10.2106/JBJS.K.00926. Fig. Several models of acquired hindfoot deformity suggest that lateral hindfoot impingement is related to a lateral shift of weight bearing from the talar dome to the lateral talus and fibula [14] as well as to talocalcaneal joint subluxation [15]. We observed symptomatic unilateral fibular impingement initially on the left foot of an 11-year-old female with an otherwise asymptomatic bilateral talocalcaneal coalition.

Supported in part by a research travel grant from the Fundacin Alfonso Martn Escudero of Madrid, Spain (E. Ramos Gavil). A radiology database was retrospectively reviewed to identify patients with an MRI diagnosis of a posterior tibial tendon tear over an approximately 5-year period from January 2003 to March 2008. 3B 61-year-old woman with hindfoot valgus, distal fibular tip periostitis, peroneus longus tendon subluxation, and subfibular impingement. 2008 Jul-Aug;47(4):288-94. doi: 10.1053/j.jfas.2008.04.004. Evaluation of MR images showed the largest proportion of patients having grade Ia (n = 26, 35%) and grade Ib (n = 36, 48%) tears, and a smaller proportion having grade II (n = 6, 8%) and grade III (n = 7, 9%) tears. The following MRI features were recorded: grade of posterior tibial tendon tear, MRI hindfoot valgus angle, lateral hindfoot impingement, peroneal tendon dislocation, and lateral malleolar bursa. These procedures include calcaneal translational osteotomies, lateral column lengthening, hindfoot arthrodesis, posterior tibial tendon reconstruction, and peroneus brevis to peroneus longus tendon transfers [19, 20]. Athletes, Return to activity or sport depends on the individual, but athletes with uncomplicated cases, Posteromedial: A key clinical finding for a patient with a posteromedial impingement is. The peroneal tendons were classified as subluxed or dislocated on MRI when they were located beyond the normal expected lateral cortical margin of the distal fibula, at the level of the retromalleolar groove (Fig. Bookshelf Before HHS Vulnerability Disclosure, Help The medial, rather than the lateral, calcaneal wall was selected because it had less variability and fewer bony protuberances. Calcaneal fractures, congenital abnormalities including absence or hyper-elasticity of the SPR, and abnormal flat or convex contours of the retromalleolar groove have also been implicated as predisposing patients to peroneal tendon subluxation-dislocation [7]. Department of Orthopaedic Surgery, Baylor Scott and WhiteTemple, Temple, TX. The .gov means its official. Keywords: dislocation, fibular tip periostitis, hindfoot valgus, peroneal tendon, pes planovalgus, subfibular impingement, subluxation. We developed a grading scheme for hindfoot valgus severity based on MRI measurement of the coronal tibiocalcaneal angle. BACKGROUND. Radiographics. Posterior tibial tendon dysfunction with secondary hindfoot valgus can lead to painful extraarticular, lateral talocalcaneal, and subfibular impingements, often necessitating surgical intervention. A, Anteroposterior radiograph shows distal fibular tip periostitis (arrowheads). Together they form a unique fingerprint. This patient group size was based on statistical power calculation. We have anecdotally noted on radiographs, however, distal fibular periostitis associated with peroneal tendon subluxation-dislocation in patients with hindfoot valgus. Finally, in stage IV, there is additional valgus angulation of the talus at the tibiotalar joint [25, 26]. 6. Another limitation was that the MRI examinations were nonweightbearing, as were many of the corresponding radiographic examinations, possibly affecting our calculations of hindfoot valgus angles. 2019 Nov;49(12):1691-1701. doi: 10.1007/s00247-019-04459-5. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. This is the American ICD-10-CM version of M75.42 - other international versions of ICD-10 M75.42 may differ. Less frequent findings in subfibular impingement included fibular tip marrow edema and contact between the fibula and calcaneus, occasionally with the formation of a calcaneal neofacet. Two additional fellowship-trained blinded musculoskeletal radiologists with 4 years (reader 1) and 3 years (reader 2) of experience subsequently independently reviewed the ankle radiographs and MRI examinations of both patient groups. Studies were retrospectively assessed by two musculoskeletal radiologists in consensus and by two additional blinded radiologists independently for the presence of peroneal tendon subluxation-dislocation, presence of subfibular impingement, and hindfoot valgus angle measurements.

Moreover, the mean MRI hindfoot valgus angle was significantly greater in combined talocalcanealsubfibular impingement compared with isolated talocalcaneal or isolated subfibular impingement. If fibular edema is related to impingement, then edema may be seen in the adjacent portion of the calcaneus, which would be absent in a stress fracture. The ankle radiographs were assessed for the presence or absence of fibular tip periostitis. Balancing the theoretic osteogenic advantages of autograft against the attendant patient morbidity remains a debatable point.6 With shared decision-making, this patient chose autograft because of the inductive properties and reduced immunogenic considerations.4 Reported results of distraction arthrodesis consistently demonstrate healing rate above 95%4 and improved hindfoot function.79 The authors' technique for subtalar distraction arthrodesis includes the use of a medially placed femoral distractor and lateral lamina spreader to aid in articular exposure, restoration of calcaneal height, and hindfoot alignment. It possibly occurs with valgus deformity associated with talocalcaneal coalition. WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. The periostitis noted in venous insufficiency and infection is more diffuse than that found in our patients with hindfoot valgus and typically extends farther proximally along the distal fibular diaphysis (Fig. Fig. PMC MRI hindfoot valgus angle was further categorized, using 10 increments as mild (716), moderate (1726), and severe (> 26).

Our study noted a significant association between peroneal tendon subluxation and moderate or severe hindfoot valgus as well as combined talocalcanealsubfibular impingement. In: Coughlin MJ, Mann RA, Saltzman CL, eds. [13], who classified a valgus angle greater than 10 as abnormal. Imaging features of subfibular impingement often include extensive lateral soft-tissue thickening between the fibula and the calcaneus (Fig. 13A, 13B, 13C ). Entrapment and thickening of the calcaneofibular ligament are also seen (Fig. 13A, 13B, 13C ). Associated with severe hindfoot WebThese impingements are sequelae of flatfoot deformity and hindfoot valgus from a variety of causes such as posterior tibial tendon (PTT) deficiency, rheumatologic disorders, 2018 May-Jun;57(3):478-483. doi: 10.1053/j.jfas.2017.10.033. Lateral wall exostosis with peroneal tendon irritation. Anterior ankle impingement is caused by traumatic or repetitive compression to the structures at the front of the ankle as the tibia and talus move towards each other during movements. Further study is needed to correlate MRI findings of lateral hindfoot impingement with clinical grading of posterior tibial tendon dysfunction, lateral hindfoot pain, surgical findings, and patient outcome after surgery. At 10 years of age, it was questioned whether the pain was related to the coalition. to maintaining your privacy and will not share your personal information without Keywords: Please enable it to take advantage of the complete set of features! An exact Mann-Whitney test was used to compare subjects with and without talocalcaneal or subfibular impingement, peroneal dislocation, or lateral adventitial bursitis with the measured MRI hindfoot valgus angle. Bethesda, MD 20894, Web Policies Calcaneal osteotomy is often necessary to correct the hindfoot valgus and lateral hindfoot impingement [1]. The typical indication for distraction arthrodesis is subtalar arthrosis in combination with loss of calcaneal height with or without subfibular impingement. Sural nerve neuroma . WebThe impingement in the lateral aspect of the hindfoot may first occur within the sinus tarsi and then involve the calcaneofibular region. This was done to decrease the number of positive search results. The radiographic volume at our institution is several times the MRI volume; therefore, our method facilitated identification of patients with hindfoot valgus who had both MR images and radio-graphs available for review. 8. Because conservative treatment options for peroneal tendon subluxation-dislocation have proven ineffective, surgical therapies, such as tendon rerouting, reconstruction or repair of the SPR, bone block procedures, and fibular groove deepening, have become the mainstay of treatment [1418]. A positive association was also seen between impingement and hindfoot valgus severity. Odds ratios were calculated to assess the utility of distal fibular periostitis as a predictor of peroneal tendon subluxation-dislocation. However, with the exception of cortical avulsions at the fibular attachment, superior peroneal retinaculum injury and subsequent peroneal tendon subluxation-dislocation are typically radiographically occult.

Search for Similar Articles Concomitant presence of peroneal tendon subluxation-dislocation and peroneal tendon abnormality, as found in our study and as noted by Donovan and Rosenberg [10], may be an additional cause of lateral ankle pain associated with hindfoot valgus. Ca = calcaneus, F = fibula, T = talus. Patients with hindfoot valgus and fibular tip periostitis were significantly more likely to have MRI evidence of peroneal tendon subluxation-dislocation (PTS) and subfibular impingement (62.9% and 68.6%, p < .001) than those without periostitis (5.7% and 0%, p < .001). In stage I, patients present with mild medial ankle pain because of posterior tibial tendon tenosynovitis or tendinosis. 8th ed. Its caused by, Anterior ankle impingement syndrome is a condition that occurs, How does it happen? Figure 1. The Cochran-Armitage trend test was used to correlate the prevalence of talocalcaneal or subfibular impingement, peroneal subluxationdislocation, and lateral adventitial bursa with grading of posterior tibial tendon tear. Reporting Templates for MRI and Water-Soluble Contrast Enema in Patients With Ileal PouchAnal Anastomosis: Experience From a Large Referral Center, Short Report. MR images from 75 patients (45 women and 30 men) with MRI evidence of posterior tibial tendon tears were evaluated for grade of posterior tibial tendon tear, hindfoot valgus angle, osseous contact or opposing marrow signal changes at the taluscalcaneus or fibulacalcaneus, peroneal tendon subluxationdislocation, and presence of lateral malleolar bursa. The lateral compartment musculature of the distal lower extremity comprises the peroneus longus and peroneus brevis muscles. If left untreated, chronic peroneal tendon subluxation-dislocation can progress to tendinosis and tenosynovitis, split tears, and even tendon rupture, particularly of the peroneus brevis tendon as it is subjected to friction while sliding in and out of the retromalleolar groove. 2019 Mar;58(2):374-376. doi: 10.1053/j.jfas.2018.08.047. 4A and 4B) or distal fibular marrow edema (n = 8, 36%) (Fig. 2021 Aug;217(2):449. doi: 10.2214/AJR.20.24754. 5.

Peroneal tendon dislocation (straight solid arrow) and split tear of peroneus brevis (curved solid arrows) also are evident. Finally, our study described associations between posterior tibial tendon tear severity, hindfoot valgus severity, and lateral hindfoot impingement; causal relationships between these findings cannot be established. The finding of distal fibular periostitis can be of particular value to the radiologist during nonweightbearing radiographic examinations, because it can suggest the presence of a higher grade of pes planovalgus than could be typically estimated on a nonweight-bearing radiograph. dislocation; fibular tip periostitis; hindfoot valgus; peroneal tendon; pes planovalgus; subfibular impingement; subluxation. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. 2 Flowchart depicts selection process for study. 4. Keywords: ankle, impingement syndrome, MRI, posterior tibial tendon. Pain and functional impairment are an unfortunate and common sequelae after calcaneal fracture.1 Etiologies of these complaints include subtalar arthrosis and malposition of the body of the calcaneus. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is typically associated with pes planovalgus The most common manifestations of talocalcaneal impingement were cystic changes and edema in the lateral process of the talus and the lateral calcaneus. tibialis posterior tenosynovitis with interstitial split tear. Draghi F, Bortolotto C, Draghi AG, Gitto S. J Ultrasound Med. Hindfoot valgus on MRI was defined as abnormal in cases with a tibiocalcaneal angle > 6 [19]. (b) Calcaneofibular impingement between the fibula and the calcaneus on the coronal weight-bearing CT scans. Magnetic resonance imaging showed a partial talocalcaneal coalition. OBJECTIVE. At the last follow-up examination, she was asymptomatic 2.5 years after the initial surgery of the left foot and 11 months after surgery on the right. Introduction. Peroneal tendon subluxation was seen in five (7%) of the 75 patients (Fig. Wolters Kluwer Health, Inc. and/or its subsidiaries. Foot Ankle Int, 20(7):422-427, 1999. These observations parallel the clinical manifestations of posterior tibial tendon dysfunction in which longitudinal arch collapse progresses through four stages based on the severity of the flatfoot deformity [25, 26]. We defined fibular tip periostitis as periostitis or bony productive change noted on anteroposterior and/or oblique radio-graphs along the lateral distal fibular cortical margin, where the SPR insertion is expected (Fig. Posterior tibial tendon dysfunction is the most common cause of acquired flatfoot and hindfoot valgus and may lead to medial and, with advanced disease, lateral ankle pain [1, 2]. It provides excellent correction of the deformity, allows early weight bearing, and preserves subtalar motion. In: Ferkel RD ed. Clipboard, Search History, and several other advanced features are temporarily unavailable. Journal of Orthopaedic Trauma35:S54-S55, August 2021.

This is followed by weight-bearing casting for another 6 weeks and subsequent gradual return to normal activities once radiographic confirmation of bone healing achieved. MRI criteria for lateral hindfoot impingement, using all imaging planes, were based on previously described CT criteria for osseous impingement [20] and on previously described MRI criteria for soft-tissue and osseous ankle impingement syndromes at other locations [2123]. The hindfoot valgus angle was Although medial ankle pain is the presenting symptom in early stages of posterior tibial tendon dysfunction, lateral ankle pain related to hindfoot valgus and lateral impingement predominates in long-standing posterior tibial tendon dysfunction [14] and often necessitates osseous correction of the foot deformity [5]. Furthermore, there was a significant positive association between the presence of combined talocalcanealsubfibular impingement and severity of posterior tibial tendon tear (p = 0.020) (Table 2). The peroneal tendons were defined as subluxed or dislocated when the tendons were partially out or lateral to the fibular groove, respectively [24]. may email you for journal alerts and information, but is committed 2). The radiographic finding of fibular tip periostitis in patients with hindfoot valgus can be a predictor of peroneal tendon subluxation-dislocation and may also suggest advanced hindfoot valgus and subfibular impingement.
