There is also pain in the posteromedial region of the ankle. Peroneal tendon subluxation was present only with advanced hindfoot valgus (p = 0.010) and impingement (p = 0.004). You may search for similar articles that contain these same keywords or you may Approximately 1.5 years after surgery, our female patient at 12.5 years old complained of the same problems on her right foot, definitely occurring only around the fibula. MeSH Fibular stress fractures typically involve the distal fibular shaft, whereas fibular tip edema is likely the result of direct osseous contact with the calcaneus. The readers were blinded to patient group. 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]. These included isolated talocalcaneal impingement (n = 6, 21%), isolated subfibular impingement (n = 8, 29%), and combined talocalcanealsubfibular impingement (n = 14, 50%). 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. Similarly, a threshold angle of 26 provided the highest prevalence of impingement findings (70%) within a group of seven patients. 2019 Mar;58(2):374-376. doi: 10.1053/j.jfas.2018.08.047. 5A, 5B). Pain localized to the lateral subtalar region is often clinically felt to represent either subtalar joint degeneration or sinus tarsi syndrome. Address correspondence to A. Donovan ([emailprotected]). Department of Orthopaedics and Sports Medicine, University of Washington, Harborview Medical Center, 325 Ninth Avenue, Seattle, WA 98104, USA. 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. In addition, the mean angle was significantly greater in combined talocalcanealsubfibular impingement compared with isolated talocalcaneal impingement (p = 0.031) or isolated subfibular impingement (p = 0.020). 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. What Is the Os Trigonum? It is important to distinguish marrow edema involving the fibula in subfibular impingement from that related to a fibular stress fracture [29]. 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. 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. OBJECTIVE. Careers. 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. We propose that the association between hindfoot valgus with distal fibular periostitis and peroneal tendon subluxation-dislocation occurs through progressive worsening of calcaneal valgus, which leads to lateral displacement of the peroneal tendons along the lateral calcaneal wall. The source of the pain is the joint below the ankle joint, called the 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). (Drawing by Nachamie H, used with permission). CLINICAL IMPACT. Fourth, the true degree of hindfoot valgus could not be assessed because our MRI studies were not weight bearing, and correlation with standing radiographs was not available. A, Anteroposterior (A) and oblique (B) radiographs of ankle show hindfoot valgus and periostitis along lateral cortical margin of fibular tip (arrowheads). The ankle radiographs and MRI studies were first evaluated in consensus by two fellowship-trained musculoskeletal radiologists with 4 and 33 years of experience. Dive into the research topics of 'Subfibular impingement: Current concepts, imaging findings and management strategies'. 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]. 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 location of marrow edema may be a helpful distinguishing feature. The purpose of this study was to describe the MRI features of this extraarticular impingement and to correlate its presence with grading of posterior tibial tendon tear and severity of hindfoot valgus in patients with posterior tibial tendon tears. 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. MRI studies were classified as showing evidence of subfibular impingement if at least one of the following criteria was present: direct contact between the fibula and calcaneus with or without apposing marrow edema and presence of pseudofacets on both sides of the fibula and calcaneus (Fig. The mean angle was significantly lower among subjects without MRI evidence of impingement (14.1; SD, 6.1) than among subjects with either isolated talocalcaneal impingement (26.5; SD, 11.0) or combined talocalcanealsubfibular impingement (27.1; SD, 7.0) (p < 0.001). Moreover, the mean MRI hindfoot valgus angle was significantly greater in combined talocalcanealsubfibular impingement compared with isolated talocalcaneal or isolated subfibular impingement. government site. 2A and 2B) or sclerosis (low T1 and low T2 marrow signal; n = 3, 15%) (Figs. Clin Orthop Relat Res. In: Coughlin MJ, Mann RA, Saltzman CL, eds. Imaging features of subfibular impingement included extensive soft-tissue thickening between the fibula and the calcaneus. 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).

Among these, 35 patients (15 men, 20 women; mean age, 60.5 years) had radiographic evidence of distal fibular periostitis and were designated as the periostitis group. The os trigonum is an extra (accessory) bone that sometimes develops behind the ankle bone (talus). Posterior Fibular Groove Deepening Procedure With Low-Profile Screw Fixation of Fibrocartilaginous Flap for Chronic Peroneal Tendon Dislocation. Extraarticular lateral hindfoot impingement is associated with advanced posterior tibial tendon tears and increased MRI hindfoot valgus angle. 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. However, imaging of the asymptomatic right foot also showed a talocalcaneal coalition, with the coalition in both feet appearing equal. The peroneal tendons and lateral malleolar bursa were examined in all patients. Additionally, the peroneal trochlea appeared particularly prominent, more so on the left than on the right foot. Distal fibular periostitis in patients with hindfoot valgus can be a reliable radiographic indicator of this entity and may suggest the presence of subfibular impingement. All rights reserved. 3. What is the extra bone in your ankle called? Careers. Peroneal tendon subluxation likely represents an end stage of lateral impingement in patients with posterior tibial tendon dysfunction. Marlyand Heights, MO: Mosby, Inc; 2007:21. A dynamic MRI protocol, whereby patients plantarflex and dorsiflex the ankle, as proposed by Shellock et al. 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. Surgery of the Foot and Ankle. This website uses cookies. MRI hindfoot valgus angle was further categorized, using 10 increments as mild (716), moderate (1726), and severe (> 26). 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. 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. Radiographic fibular tip periostitis in patients with hindfoot valgus can be a predictor of PTS and subfibular impingement, potentially warranting further advanced imaging evaluation. Readers were trained to interpret the images using the aforementioned criteria for each imaging finding. 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. 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. important when there are symptoms of anterior ankle impingement. Although the hindfoot valgus angle is likely underestimated in our study because the MRI studies were not weight bearing, it may still be useful for assessing anatomic distortions [27]. Gallie WE.

This patient group size was based on statistical power calculation. The prevalence of impingement was significantly increased with greater MRI hindfoot valgus angle (p < 0.001). The purposes of this study were to assess the association between the radiographic finding of distal fibular periostitis and peroneal tendon subluxation-dislocation in patients with hindfoot valgus deformities and to propose this periostitis as a radiographic predictor of chronic peroneal tendon subluxation-dislocation. Fig. HHS Vulnerability Disclosure, Help 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. 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 site needs JavaScript to work properly. Most patients had mild (n = 31, 41%) or moderate (n = 25, 33%) hindfoot valgus (Fig. Hence, treatment should be determined accordingly. WebThese impingements are sequelae of flatfoot deformity and hindfoot valgus from a variety of causes such as posterior tibial tendon (PTT) deficiency, rheumatologic disorders, Calcaneal osteotomy is often necessary to correct the hindfoot valgus and lateral hindfoot impingement [1]. 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. A positive association was also seen between impingement and hindfoot valgus severity. Soft-tissue repair alone in patients with posterior tibial tendon dysfunction may lead to unsatisfactory surgical outcome and persistent lateral ankle pain. Your message has been successfully sent to your colleague. Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. 6D Radiographic findings in distal fibular periostitis. This finding suggests that distal fibular periostitis may be a good radiographic indicator of more severe pes planovalgus and that its presence may alert the interpreting radiologist to the possibility of a concomitant advanced abnormality, such as subfibular impingement. Fig. 3A and 3B) at the opposing surfaces of the lateral talar process and the lateral wall of the calcaneus. Cases were retrospectively identified by a keyword search of reports of ankle MRI examination performed at our institution (NYU Langone Health) for the terms hindfoot valgus and pes planovalgus. Patients were excluded from the dataset if MRI or radiographic images were of poor technical or diagnostic quality. 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. Fig. Bookshelf There were several limitations to our study. 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. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Associated with severe hindfoot deformity, subfibular impingement can be secondary to posterior tibial tendon dysfunction, calcaneal fracture malunion, or neuropathic or inflammatory arthritidies. 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]. 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). Bednarz PA, Beals TC, Manoli A. Subtalar distraction bone block fusion: an assessment of outcome. Peroneal tendon subluxation was seen in five (7%) of the 75 patients (Fig. Keywords: 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]. Additional parameters included 1220 920 field of view range, 256512 128256 matrix range, 45 mm slice thickness with 1.01.5 mm intersection gap, and echotrain length of 48. Federal government websites often end in .gov or .mil. 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. 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). Tenderness at the front of the ankle when touched. 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. Correction of hindfoot valgus, however, may not relieve lateral ankle pain if the peroneal tendon abnormality is not addressed. The study group was composed of 75 patients: 45 women, 30 men, mean age 58 years (age range, 2990 years) with MRI evidence of a posterior tibial tendon tear. collapse of the medial longitudinal arch. Patients who had radiographic diffuse fibular periostitis and bony productive changes that could have been clinically or radiographically attributed to other causes, such as posttraumatic fracture deformities, vascular insufficiency, or infectious processes, were also excluded from the primary dataset. We have anecdotally noted on radiographs, however, distal fibular periostitis associated with peroneal tendon subluxation-dislocation in patients with hindfoot valgus. Sign in. persistent subfibular pain after calcaneal fractures. It remains unclear whether this is primarily due to bony or soft-tissue impingement. Aside from posterior tibial tendon dysfunction, there are several additional causes of hindfoot valgus, such as healed intraarticular calcaneal fractures [30], neuropathic arthropathy [31], and inflammatory arthritides [12], which may lead to extraarticular impingement. Lateral hindfoot pain in patients with flatfoot deformity is frequently attributed to subfibular impingement. It remains unclear whether this is primarily due to bony or soft-tissue impingement. No studies have used weight-bearing CT scans to evaluate subfibular impingement. 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).

Bilateral Triple Talocalcaneal, Calcaneonavicular, and Talonavicular Tarsal Coalition: A Case Report. The interpreting radiologist should recognize these associations and possibly recommend advanced cross-sectional imaging, such as MRI, as clinically indicated. Clipboard, Search History, and several other advanced features are temporarily unavailable. 1997;18:613615. This condition, sometimes called footballers ankle, causes pain in the front of the ankle joint. 6B). These muscles are responsible for eversion of the foot and plantar flexion of the ankle and act as dynamic lateral stabilizers of the ankle joint [1]. Periostitis predicted PTS with 91.7% sensitivity and 71.7% specificity. How does anterior ankle impingement happen? 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. 4A and 4B) or distal fibular marrow edema (n = 8, 36%) (Fig. In summary, in patients with hindfoot valgus, radiographic evidence of focal distal fibular tip periostitis suggests chronic SPR stress and raises the likely possibility of peroneal tendon subluxation-dislocation, subfibular impingement, and advanced hind-foot valgus deformity. Fisher's exact test was used to evaluate associations among these findings. To our knowledge, there are no other radiographic markers of peroneal tendon subluxation-dislocation. For radiographic fibular periostitis, the readers were concordant on 95.7% of their interpretations, having almost perfect agreement ( = 0.91). Symptomatic subfibular and/or lateral talocalcaneal impingement in pediatric patients may result from an accessory anterolateral talar facet (AALTF).

Cyst formation and/or sclerosis in this region Access personal subscriptions, purchases, paired institutional or society access and free tools such as email alerts and saved searches. 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. 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. Asterisk indicates poor definition of superior peroneal retinaculum at attachment to fibula. The treatment for anterior impingement in the ankle can include, Main points. There were 28 cases (37%) with lateral hindfoot impingement. 6% (132/2119) 4. DOI: 10.2106/00004623-200211000-00015 PMID: 12429762. Ca = calcaneus, F = fibula, T = talus. Physical exam.

Figure 1. Specifically, the threshold angle of 16 was used to distinguish mild from moderate hindfoot valgus based on a receiver operating characteristic (ROC) analysis to assess the MRI hindfoot valgus angle as a predictor for a finding of impingement. Our data support previous studies showing that talocalcaneal impingement may represent an earlier stage of posterior tibial tendon dysfunction than subfibular or combined talocalcanealsubfibular impingement [20]. Epub 2017 Dec 19. It provides excellent correction of the deformity, allows early weight bearing, and preserves subtalar motion. Foot Ankle Int. 1. Websummary Tibiotalar Impingement is a source of anterior ankle pain that is most often caused by osteophyte impingement in the anterior tibiotalar joint. 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. Foot Ankle. Finally, in stage IV, there is additional valgus angulation of the talus at the tibiotalar joint [25, 26]. Peroneal tendons (solid arrow) are dislocated from retromalleolar groove.

This stripping of the SPR allows the peroneal tendons to slide out of the retromalleolar groove. J Bone Joint Surg Am. CLINICAL IMPACT. 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 tissues that are affected become damaged and inflamed, causing the pain typical of ankle impingement. fibular overgrowth; fibulocalcaneal impingement; growing child; position of distal fibular physis; talocalcaneal coalition. The keyword search yielded the records of 220 consecutively enrolled adult patients with hindfoot valgus and both ankle radiographs and MRI examinations. Further distraction force is applied through the laterally based lamina spreader until a talar declination angle similar to the opposite side is achieved. The 2 spurs abut during ankle dorsiflexion (Figure 2). RESULTS. Anteroposterior radiograph shows periostitis at level of insertion of superior peroneal retinaculum (SPR) (arrowheads). 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. 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). Bethesda, MD 20894, Web Policies Fig. Peroneal tendon displacement, previously not described in association with posterior tibial tendon dysfunction, may also be encountered with advanced hindfoot valgus and lateral impingement. Distal fibular periostitis in patients with hindfoot valgus can be a reliable radiographic indicator of this entity and may suggest the presence of subfibular impingement. Taljanovic MS, Alcala JN, Gimber LH, Rieke JD, Chilvers MM, Latt LD.

Hindfoot valgus with subfibular impingement. FOIA To the best of our knowledge, these relationships have not been described previously in the literature. Is there an ICD 10 for left At the level of the ankle joint, the peroneus longus and peroneus brevis tendons share a common synovial sheath within the retromalleolar groove of the distal fibula in which the peroneus brevis tendon is anteromedial to the peroneus longus tendon [2, 3]. The authors thank James Babb for his assistance with statistical analysis. The medial, rather than the lateral, calcaneal wall was selected because it had less variability and fewer bony protuberances. In patients with hind-foot valgus, the presurgical status of the peroneal tendons is particularly important because the tendons can be used in surgical treatment [11, 12]. An additional 35 consecutively assigned patients without fibular periostitis composed the age- and sex-matched control group (15 men, 20 women; mean age, 59.8 years). A common source of chronic ankle pain among athletes is anterior ankle impingement. The prevalence of impingement correlated with MRI hindfoot valgus angle (p < 0.001) (Table 3). This case depicts this procedure applied to a 42-year-old man who had undergone nonoperative treatment for a calcaneal fracture 4 years prior. In stage I, patients present with mild medial ankle pain because of posterior tibial tendon tenosynovitis or tendinosis. The finding of periostitis was specific and highly sensitive for predicting peroneal tendon subluxation-dislocation. All statistical tests were conducted at the two-sided 5% significance level with SAS software (version 9.4, SAS Institute). 1993;75:331341. Unable to load your collection due to an error, Unable to load your delegates due to an error. 2. Dashed lines (C) indicate tibial and calcaneal axes for hindfoot valgus measurements. This may have resulted in falsely high MRI prevalence of lateral impingement in our patient population. MRI studies can help identify the size of peroneal tendon tear and identify concomitant injuries to nearby structures. B, 34-year-old woman with acute inversion injury (not in study sample). Fig. 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. 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. 6). Lateral hindfoot pain in patients with flatfoot deformity is frequently attributed to subfibular impingement. Introduction. Bookshelf Hindfoot valgus on MRI was defined as abnormal in cases with a tibiocalcaneal angle > 6 [19]. Subfibular impingement has been described in patients with flatfoot. Odds ratios were calculated to assess the utility of distal fibular periostitis as a predictor of peroneal tendon subluxation-dislocation. Protocols varied minimally and mostly consisted of an axial fat-suppressed T2-weighted fast spin-echo (FSE) sequence (TR/TE, 40004500/5060), an axial fat-suppressed and nonfat-suppressed proton-density FSE sequence (TR/TE, 25003500/3040), a coronal fat-suppressed proton-density FSE sequence, a sagittal fat-suppressed proton-density FSE sequence, and a sagittal T1-weighted FSE sequence (TR/TE, 400800/1020). The readers had substantial interreader agreement and were concordant in detecting peroneal tendon subluxation-dislocation (82.9%, = 0.66) and subfibular impingement (88.6%, = 0.74). We theorize that lateral displacement of the peroneal tendons by calcaneal valgus and/or direct fibular-calcaneal contact, as noted in subfibular impingement, causes chronic stress and periosteal stripping at the fibular attachment of the SPR, resulting in distal fibular periostitis (Fig. 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. The https:// ensures that you are connecting to the Tarsal coalitions in the adult population: does treatment differ from the adolescent? may email you for journal alerts and information, but is committed Furthermore, this video demonstrates the restoration of lost height and coronal plane alignment through the combined use of a medially based femoral distractor and a laterally applied lamina spreader. Thus, grading of posterior tibial tendon tears and assessment of hindfoot valgus angles on MRI may aid in the detection of early lateral impingement.
