Surgery of the Foot and Ankle. Patient B is a 68-year-old woman who underwent a subtalar fusion in 2008 for severe subtalar arthrosis, with subsequent hardware removal a year later. Dashed lines (C) indicate tibial and calcaneal axes for hindfoot valgus measurements. B, Coronal fat-suppressed proton-density MR image shows subfibular impingement with direct contact between fibula (F) and calcaneus (Ca) and degenerative opposing cysts (open arrows). What causes Subfibular impingement? To our knowledge, there are no other radiographic markers of peroneal tendon subluxation-dislocation. Editorial Comment on "Fibular Tip Periostitis: New Radiographic Sign Predictive of Chronic Peroneal Tendon Subluxation-Dislocation in Pes Planovalgus". pes planus . Thirty-five patients with radiographic fibular tip periostitis and 35 ageand sex-matched individuals without periostitis were selected from among 220 consecutively registered patients with hindfoot valgus who had undergone both ankle radiography and MRI. These radiographic associations should be recognized by the radiologist, and MRI may be recommended as clinically indicated. At 10 years of age, it was questioned whether the pain was related to the coalition. M75.42 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 6D Radiographic findings in distal fibular periostitis. Although the imaging protocols were slightly different, the MRI protocol in most patients consisted of two sagittal acquisitions (T1-weighted spin-echo images and inversion recovery); two axial acquisitions (T1-weighted or intermediate-weighted and T2-weighted fast spin-echo, with or without fat suppression); a single coronal plane (T1-weighted or intermediate-weighted or T2-weighted fast spin-echo with fat suppression). It remains unclear whether this is primarily due to bony or soft-tissue impingement. Address correspondence to A. Donovan ([emailprotected]). B, Axial (B) and coronal (C) fat-suppressed proton-density MR images depict subfibular impingement with direct contact between fibula (F) and calcaneus (Ca) and apposing marrow edema (open arrows). Interreader agreement on the hindfoot valgus measurement was assessed by intraclass correlation (ICC) for the absolute agreement of individual measurements. - "Assessment of Bony Subfibular Impingement in Flatfoot Patients 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]. How does it happen? J Foot Ankle Surg. The hindfoot valgus measurements performed by the two readers had an ICC value of 0.87, corresponding to excellent agreement. The hindfoot valgus angle was Subtalar distraction arthrodesis is a hindfoot reconstructive procedure designed to treat posttraumatic sequelae of certain calcaneal fractures. Together they form a unique fingerprint. 4. 3B 61-year-old woman with hindfoot valgus, distal fibular tip periostitis, peroneus longus tendon subluxation, and subfibular impingement. J Foot Ankle Surg. The ankle MRI studies were performed on several different 1.5-T MR units (n = 73) and an open 0.2-T (n = 2) MR unit. There is a lot going on in this case: hindfoot valgus with extra-articular talocalcaneal impingement; suggestion of developing calcaneofibular impingement with subortical cysts present at the lateral malleolar tip. We observed symptomatic unilateral fibular impingement initially on the left foot of an 11-year-old female with an otherwise asymptomatic bilateral talocalcaneal coalition. Displaced Flap Tears of the Triangular Fibrocartilage Complex: Frequency, Flap Location, and the Comma Sign on Wrist MRI, Review. Clipboard, Search History, and several other advanced features are temporarily unavailable. After fixation with height-preserving fully threaded cancellous screws and careful closure, nonweight-bearing casting is provided for six weeks. Reconstruction and correction of symptomatic pes planovalgus alignment is a complex and difficult undertaking, often requiring a combination of bone and soft tissue surgical procedures to re-create proper alignment and restore the medial longitudinal arch of the foot. Associated with severe hindfoot deformity, Subtalar distraction bone block arthrodesis. We believe this may be related to entrapment of fat and even the calcaneofibular ligament between the two bones, with the development of fat atrophy and fibrosis [21]. Readers 1 and 2 both confirmed the findings of the consensus reading and found that peroneal tendon subluxation-dislocation was present significantly more often in the periostitis group (reader 1, 23/35 [65.7%]; reader 2, 30/35 [85.7%]) than in the control group (reader 1, 0/35; reader 2, 5/35 [14.3%]) (both readers, p < .001) (Table 1). Combined talocalcanealsubfibular impingement was seen in 12% (n = 8/62) of grade I, 33% (n = 2/6) of grade II, and 57% (n = 4/7) of grade III posterior tibial tendon tears. Chan SC, Alexander IJ. These included isolated talocalcaneal impingement (n = 6, 21%), isolated subfibular impingement (n = 8, 29%), and combined talocalcanealsubfibular impingement (n = 14, 50%). collapse of the medial longitudinal arch. Cyst formation and/or sclerosis in this region Fibula 96%. Ca = calcaneus, F = fibula, T = talus. The source of the pain is the joint below the ankle joint, called the Disclaimer, National Library of Medicine Both readers found that the valgus angles were larger in patients with fibular tip periostitis (reader 1, 32.0; reader 2, 33.1) than in those without it (reader 1, 27.2; reader 2, 26.9) (reader 1, p = .01; reader 2, p = .002). It is connected to the talus by a fibrous band. Accessibility Interreader agreement on these findings was assessed by calculation of Cohen kappa coefficients and concordance rates. We developed a grading scheme for hindfoot valgus severity based on MRI measurement of the coronal tibiocalcaneal angle. For more information, please refer to our Privacy Policy. Another, scarcely recognized risk factor for the development of peroneal tendon subluxation-dislocation is osseous malalignment of the foot and ankle, specifically hindfoot valgus in adults with acquired flatfoot deformity. They also viewed a slideshow with two or three key images illustrating both positive and negative findings. lateral ankle pain due to subfibular impingement is a late symptom. 9. The treatment for anterior impingement in the ankle can include, Main points. Subfibular impingement has been described in patients with flatfoot. The tissues that are affected become damaged and inflamed, causing the pain typical of ankle impingement. Periostitis may develop as the result of direct contact between the calcaneus and fibula (occasionally with the formation of a neofacet) and/or chronic stress and stripping of the SPR caused by crowding and lateral displacement of the peroneal tendons by the abutting distal fibula and calcaneus. WebThe frequency of subfibular impingement was also statistically higher in the group with periostitis than in the group without it (p < .001). 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. Please try after some time. 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. persistent subfibular pain after calcaneal fractures. In our study, both the consensus and the independent interpretations showed that in patients with hindfoot valgus, peroneal tendon subluxation-dislocation was seen significantly more often in patients with radiographic evidence of distal fibular periostitis than in those without it. An official website of the United States government. Fig. The prevalence of impingement correlated with MRI hindfoot valgus angle (p < 0.001) (Table 3). The typical deformities of varus, expanded width, and lost height combine to create a rigid hindfoot with limited motion.2 When severe deformity exists, these problems can rarely be addressed with in situ fusion alone. 5A, 5B). Thus, grading of posterior tibial tendon tears and assessment of hindfoot valgus angles on MRI may aid in the detection of early lateral impingement.

Keywords: ankle, impingement syndrome, MRI, posterior tibial tendon. 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. Introduction. The authors thank James Babb for his assistance with statistical analysis. MRI hindfoot valgus angle was further categorized, using 10 increments as mild (716), moderate (1726), and severe (> 26). Mean valgus angle measurements were also significantly greater in patients with peroneal tendon subluxation-dislocation (32.1) than in those without (26.1) (p = .002). In stage II, there is a tear of the posterior tibial tendon with loss of normal alignment of the foot. Copyright 2017 American College of Foot and Ankle Surgeons. Reprints: Robert Probe, MD, Department of Orthopaedic Surgery, Baylor Scott and WhiteTemple, Temple, TX 2401 S 31st St. Temple, TX, 76508 (e-mail: [emailprotected]). The threshold angles of 16 and 26 used in the definitions were chosen to optimize the statistical power of the study for detecting an association between the hindfoot valgus classification and the frequency of talocalcaneal or subfibular impingement. This impingement may cause pain and disability and may limit athletic performance in high-level athletes. Magnetic resonance imaging showed a partial talocalcaneal coalition. Main points. Twenty-eight cases (37%) of lateral hindfoot impingement were identified, including six talocalcaneal, eight subfibular, and 14 talocalcanealsubfibular impingements. At 14 months postoperatively, the patient was free of pain with unrestricted movement, although the follow-up imaging studies showed complete bony fusion on the medial aspect of the coalition between the talus and calcaneus. METHODS. WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Clinical or radiographic grading scales for hindfoot valgus severity are lacking, although the normal angle was previously defined as 6 or less based on CT measurements [19]. Interestingly, MR images illustrating peroneal tendon dislocation in patients with severe hindfoot valgus secondary to posterior tibial tendon dysfunction have been published previously without addressing this association [32].

The demonstrated technique uses a vertical posterolateral approach allowing sufficient exposure of the lateral exostosis for its removal. risks included lateral plantar nerve irritation and FHL impingement from long interlocking screw . 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. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. Therefore, early detection of impingement is beneficial for successful surgical results. Foot function after subtalar distraction bone-block arthrodesis: a prospective study. 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. How its caused/treatment. Understanding the Lymphatics: An Updated Review of the N Category of the AJCC 8th Edition for Urogenital Cancers, Editorial Comment. Jonathan R.M. fibular overgrowth; fibulocalcaneal impingement; growing child; position of distal fibular physis; talocalcaneal coalition. B, Anteroposterior (A) and oblique (B) radiographs of ankle show hindfoot valgus and periostitis along lateral cortical margin of fibular tip (arrowheads). RESULTS. 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. Lateral wall exostosis with peroneal tendon irritation. 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 prevalence of impingement was significantly increased with greater MRI hindfoot valgus angle ( p < 0.001). Lateral hindfoot impingement is, The clinical test for anterolateral ankle impingement is the impingement test or Molloy-Bendall test. 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. Before J Bone Joint Surg. There were several limitations to our study, including a small patient sample and retrospective selection of patients. In: Ferkel RD ed. The typical indication for distraction arthrodesis is subtalar arthrosis in combination with loss of calcaneal height with or without subfibular impingement. Before 6C Radiographic findings in distal fibular periostitis. Peroneal tendon dislocation (straight solid arrow) and split tear of peroneus brevis (curved solid arrows) also are evident. 4B 54-year-old man with pes planovalgus, distal fibular periostitis, subfibular impingement, peroneal tendon dislocation, and peroneus brevis split tear. Talocalcaneal and subfibular impingement in symptomatic flatfoot in adults There appear to be two frequently occurring extra-articular sources of bone impingement in the lateral aspect of the hindfoot in adults with symptomatic severe flatfoot deformity. The powerful medially based distractor is lengthened until a slight hindfoot valgus position is achieved. Tenderness is most seen in passive ankle inversion and passive plantar flexion. Foot Ankle Int, 20(7):422-427, 1999. Peroneal tendon subluxation likely represents an end stage of lateral impingement in patients with posterior tibial tendon dysfunction. 2018 May-Jun;57(3):478-483. doi: 10.1053/j.jfas.2017.10.033. The MRI studies were examined for the presence of peroneal tendon subluxation-dislocation, the presence of extraarticular subfibular impingement, and the degree of hindfoot valgus. In addition, lateral ankle pain in patients with posterior tibial tendon dysfunction has been attributed to sinus tarsi pathology, fibular stress fractures [12], and lateral adventitial bursa [13]. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. 1943;25:731736. The ROC analysis showed that the threshold value of 16 resulted in a diagnostic test with the highest average of sensitivity and specificity. The prevalence of talocalcanealsubfibular impingement significantly increased with grading of posterior tibial tendon tear (p = 0.018). Associated with severe hindfoot deformity, 2001;83:849854. Soft-tissue repair alone in patients with posterior tibial tendon dysfunction may lead to unsatisfactory surgical outcome and persistent lateral ankle pain. Future studies with recently introduced weight-bearing MRI capabilities [28] may aid in correlating our MRI hindfoot valgus grading scale with weight-bearing radiographs and with clinical stages of posterior tibial tendon dysfunction. Tenderness at the front of the ankle when touched. 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. 2012 Sep 5;94(17):1584-94. doi: 10.2106/JBJS.K.00926. However, the flatfoot deformity is mobile. important when there are symptoms of anterior ankle impingement. In stage I, patients present with mild medial ankle pain because of posterior tibial tendon tenosynovitis or tendinosis. 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]. PMC Anteroposterior radiograph shows smooth periosteal reaction (arrows) along distal fibular diaphysis secondary to callus formation. No studies have used weight-bearing CT scans to 1997;18:785791. C, Axial (B) and coronal (C) fat-suppressed proton-density MR images depict subfibular impingement with direct contact between fibula (F) and calcaneus (Ca) and apposing marrow edema (open arrows). [13], who classified a valgus angle greater than 10 as abnormal. A positive association was also seen between impingement and hindfoot valgus severity. 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. It is important to distinguish marrow edema involving the fibula in subfibular impingement from that related to a fibular stress fracture [29]. AJR Am J Roentgenol. Clinical history of posterior tibial tendon dysfunction was provided for the majority of patients (n = 45, 60%). The subsequent heel valgus that develops as a result of the altered anatomic alignment of the talus and calcaneus can laterally displace the peroneal tendons, causing them to dislocate from the retromalleolar groove [10]. Peroneal tendon subluxation-dislocation is a dynamic phenomenon and may have been underestimated on the static MR images. Additionally, future prospective studies could investigate whether the presence of radiographic fibular tip periostitis in all patients, not solely those with hindfoot valgus, is a reliable predictor of chronic peroneal tendon subluxation-dislocation. This case depicts this procedure applied to a 42-year-old man who had undergone nonoperative treatment for a 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). Athletes perform this by dorsiflexing the ankle while simultaneously palpating and pressing the anteromedial ankle joint area. Pain at the end-range of stretching your toes toward your shin. 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. B, 34-year-old woman with acute inversion injury (not in study sample). However, imaging of the asymptomatic right foot also showed a talocalcaneal coalition, with the coalition in both feet appearing equal. Fig. Subfibular impingement, which refers to either soft tissue or osseous impingement between the distal fibula and calcaneus, is characterized by pain at the lateral aspect of the hindfoot and often coexists with talocalcaneal and sinus tarsi impingement. D, 73-year-old woman with healed fracture deformity (not in study sample). The radiologist should be familiar with these different entities when encountering patients with lateral ankle pain and with MRI features of lateral impingement. Fig. The flattening of the medial arch of the foot that occurs in acquired flatfoot is most commonly attributed to posterior tibial tendon insufficiency [8, 9]. 3A and 3B) at the opposing surfaces of the lateral talar process and the lateral wall of the calcaneus.

Patients were placed in the supine position, with the ankle in mild (20) plantar flexion. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is American Volume , 01 Nov 2002, 84 (11): 2005-2009. Fig. sharing sensitive information, make sure youre on a federal Radiographic fibular tip periostitis in patients with hindfoot valgus can be a predictor of PTS and subfibular impingement, potentially warranting further advanced imaging evaluation. Among the 24 patients with fibular periostitis and MRI evidence of impingement, 18 (75.0%) also had peroneal tendon subluxation-dislocation (Figs. Furthermore, with the consensus opinions from MRI interpretation as a reference standard for detecting peroneal tendon subluxation-dislocation, radiographic fibular periostitis was predictive of peroneal subluxation-dislocation with sensitivity of 91.7% and specificity of 71.7%. 6). Furthermore, cases were identified by a keyword search of ankle MRI reports rather than a keyword search of radiographic reports. 1A Proposed mechanism for development of distal fibular periostitis in individuals with hindfoot valgus. 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. Please enable it to take advantage of the complete set of features! WebNo studies have used weight-bearing CT scans to evaluate subfibular impingement. This stripping of the SPR allows the peroneal tendons to slide out of the retromalleolar groove. Please enable it to take advantage of the complete set of features! Radiographics. Marlyand Heights, MO: Mosby, Inc; 2007:21. 5A 78-year-old man with hindfoot valgus, distal fibular tip periostitis, peroneal tendon dislocation, and subfibular impingement. Once this position is reached, routine arthrodesis surface preparation is performed followed by direct measurement of defect size. Published by Elsevier Inc. All rights reserved.

We noted an increased prevalence of impingement, particularly the more advanced, combined talocalcanealsubfibular impingement, with advanced posterior tibial tendon tears. 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). 2 Flowchart depicts selection process for study. Unable to load your collection due to an error, Unable to load your delegates due to an error. Statistical computations were performed using SAS version 9.0 (SAS Institute). In the authors' opinion, when satisfactory lateral wall decompression can be achieved with a posterolateral vertical incision, it is preferred because it avoids the creation of a transverse limb that may require closure with incisional tension.5 A corollary to this is that when necessary, the extensile approach has also been shown useful when necessary with acceptable healing rates. The peroneal tendons and lateral malleolar bursa were examined in all patients. Additional known causes of peroneal tendon subluxation-dislocation include an accessory peroneus quartus or a low-lying peroneus brevis muscle belly, which can crowd the retromalleolar groove and stretch the SPR [6]. CLINICAL IMPACT. BackgroundThis study assessed the average time to return to training and official game participation after modified Brostrm operation (MBO) in elite athletes.MethodsSixty athletes diagnosed with lateral ankle instability underwent MBO from October 2011 to December 2013. A common source of chronic ankle pain among athletes is anterior ankle impingement. Anterior Shoulder Instability in the Aging Population: MRI Injury Pattern and Management. Hence, treatment should be determined accordingly. Their average age was 19.3 years, and the average follow-up time was 28.8 months. The readers were blinded to patient group. The level of agreement was interpreted as poor if the kappa value was less than zero, slight if the kappa value was greater than zero but 0.2 or less, fair if the kappa value was greater than 0.2 but 0.4 or less, moderate if the kappa value was greater than 0.4 but 0.6 or less, substantial if the kappa was greater than 0.6 but 0.8 or less, and almost perfect if the kappa value was greater than 0.8. Odds ratios were calculated to assess the utility of distal fibular periostitis as a predictor of peroneal tendon subluxation-dislocation. This finding raises the possibility that distal fibular periostitis may be a previously un-described radiographic sign of chronic peroneal tendon subluxation-dislocation. 1st ed. 2015 Jan-Feb;35(1):179-99. doi: 10.1148/rg.351130062. The hindfoot valgus angle was statistically larger in the group with periostitis than in the control group (p = .01.002) and among patients with versus those without peroneal tendon subluxation-dislocation (p = .002 to p < .001). Therefore, the symptoms were suspected to have been caused only by fibulocalcaneal impingement owing to a relatively long fibula. Keywords: (Drawing by Nachamie H, used with permission). In contrast, stage III represents severe incompetence of the posterior tibial tendon and progression to a fixed flatfoot deformity. 1A, 1B, 1C). 6. Additional parameters included a 110160 110150 mm FOV, 256512 128256 matrix, and 3- to 4-mm slice thickness. The major stabilizer of the peroneal tendons and their sheath at this point is the superior peroneal retinaculum (SPR). Conservative Treatment 34%. There was a positive association between tendon subluxation and the presence of impingement (p = 0.006); the former was identified only in cases of impingement and mostly with combined talocalcanealsubfibular impingement (n = 4, 80%). With the opinions from the consensus interpretation as a reference standard, sensitivity, specificity, and accuracy were calculated for each of the blinded readers' assessments of radiographic fibular tip periostitis, peroneal tendon subluxation-dislocation on MRI, and subfibular impingement on MRI. Further distraction force is applied through the laterally based lamina spreader until a talar declination angle similar to the opposite side is achieved. 2008 Jul-Aug;47(4):288-94. doi: 10.1053/j.jfas.2008.04.004. Federal government websites often end in .gov or .mil. This case depicts this procedure applied to a 42-year-old man who had undergone nonoperative treatment for a calcaneal fracture 4 years prior. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Anterior ankle impingement syndrome is a condition that occurs when bone spurs form in the front of the ankle joint. Bookshelf 1B). The purpose of this study was to evaluate the previously undescribed association between radiographic fibular tip periostitis and MRI evidence of peroneal tendon subluxation-dislocation in patients with hindfoot valgus. Medical records were reviewed and the clinical details recorded included patient age, sex, involved side, and clinical indication for the MRI study. In a minority of cases of acute trauma, a small cortical avulsion at the fibular insertion of the SPR may be the only radiographic indicator of the injury and of potential acute peroneal tendon subluxation-dislocation. Fig. This, in turn, causes chronic stress and tension on the SPR at its fibular attachment, and secondary stripping of the SPR results in the radiographic evidence of chronic fibular tip periostitis and productive changes. Please enable scripts and reload this page. SPR abnormalities are known to lead to peroneal tendon subluxation and dislocation. Fig. 2009 Sep;193(3):672-8. doi: 10.2214/AJR.08.2215. Statistical significance was defined as a p value less than 0.05. Fig. MRI studies can help identify the size of peroneal tendon tear and identify concomitant injuries to nearby structures. The MRI hindfoot valgus angle was measured on the most posterior coronal image that included the tibia and calcaneus by intersecting a line along the long axis of the tibia and a line along the medial wall of the calcaneus (Fig. (a) Sinus tarsi impingement between the lateral process of the talus and the superior aspect of the calcaneus seen on sagittal weight-bearing CT scans. The location of marrow edema may be a helpful distinguishing feature. Peroneal tendon displacement, previously not described in association with posterior tibial tendon dysfunction, may also be encountered with advanced hindfoot valgus and lateral impingement. Foot Ankle. 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. The degree of hindfoot valgus was significantly greater in patients with periostitis than in those without it and in patients with peroneal tendon subluxation-dislocation than in those without it. Lateral hindfoot impingement is bony abutment of the talus and calcaneum (talocalcaneal impingement) and of the fibula (subfibular impingement) with entrapment of the lateral soft tissues of the hindfoot.
