Carr JB, Hansen ST, Benirschke SK. Is there an ICD 10 for left The finding of periostitis was specific and highly sensitive for predicting peroneal tendon subluxation-dislocation. 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 readers were blinded to patient group. 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. It provides excellent correction of the deformity, allows early weight bearing, and preserves subtalar motion. 2015 Jan-Feb;35(1):179-99. doi: 10.1148/rg.351130062. 2012 Jun;17(2):195-204. doi: 10.1016/j.fcl.2012.03.004. Fig. Conservative Treatment 34%. The calculated odds ratio for fibular periostitis as a predictor of peroneal tendon subluxation-dislocation was 29.2 (95% CI, 5.9144.9). 1B). 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 ). The Journal of Bone and Joint surgery. The included patients were 18 years old and older, had hindfoot valgus, and underwent both radiographic and MRI examinations of the ankle between January 2015 and December 2018. Pain on the front and/or outside of the ankle joint. 1997;18:613615. Nerve Entrapment Syndromes of the Elbow, Forearm, and Wrist. risks included lateral plantar nerve irritation and FHL impingement from long interlocking screw . Hindfoot valgus on MRI was defined as abnormal in cases with a tibiocalcaneal angle > 6 [19]. 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. The blinded readers had substantial or almost perfect agreement on all imaging interpretations (concordance rate, 82.9-95.7%; = 0.66-0.91). This condition, sometimes called footballers ankle, causes pain in the front of the ankle joint. and transmitted securely. 1B Proposed mechanism for development of distal fibular periostitis in individuals with hindfoot valgus. HHS Vulnerability Disclosure, Help 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%. Symptomatic subfibular and/or lateral talocalcaneal impingement in pediatric patients may result from an accessory anterolateral talar facet (AALTF). 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].

Abballe (, Fibular Tip Periostitis: New Radiographic Sign Predictive of Chronic Peroneal Tendon Subluxation-Dislocation in Pes Planovalgus, Clinical Perspective. Lateral ankle pain in patients with hindfoot valgus may have a variety of causes, the most important of which is subfibular impingement. Multiple total ankle designs reportedly cause symptomatic gutter impingement in patients post-operatively. In our study, lateral hindfoot impingement was more common in patients with advanced posterior tibial tendon tear and with a greater MRI hindfoot valgus angle. Most patients had mild (n = 31, 41%) or moderate (n = 25, 33%) hindfoot valgus (Fig. Clin Orthop Relat Res. 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.

This impingement is one of the consequences of advanced hindfoot valgus, along with talocalcaneal and, ultimately, calcaneofibular impaction. 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. Extraarticular lateral hindfoot impingement with posterior tibial tendon tear: MRI correlation. 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]. 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. 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. 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]. J Bone Joint Surg. Bookshelf Posteromedial: A key clinical finding for a patient with a posteromedial impingement is tenderness to the posteromedial aspect upon inversion with the ankle in plantar flexion. 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.

Surgery of the Foot and Ankle. 1. Diagnosis is made 8th ed. 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]. Wolters Kluwer Health 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. Subfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. Lateral hindfoot impingement, with extra-articular talocalcaneal impingement and subfibular (calcaneofibular) impingement. J Foot Ankle Surg.

A, Anteroposterior (A) and oblique (B) radiographs of ankle show hindfoot valgus and periostitis along lateral cortical margin of fibular tip (arrowheads). How does it happen? A bed for the peroneal tendons was created around the remaining epiphysis of the fibula, and the fibular ligaments were reattached with Arthrex anchors (Arthrex, Naples, FL). 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). We observed symptomatic unilateral fibular impingement initially on the left foot of an 11-year-old female with an otherwise asymptomatic bilateral talocalcaneal coalition. CT (not shown) depicted peroneal tendon dislocation. 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). At the calcaneus, the marrow findings were mainly seen at the junction of the calcaneal tuberosity with the anterior process of the calcaneus. Institutional review board approval was obtained before participants were included in this retrospective study. Subperiosteal shortening of the fibula was performed at when she was 11 years old. Patients with minimal tendinosis or isolated tenosynovitis were excluded. important when there are symptoms of anterior ankle impingement. The tissues that are affected become damaged and inflamed, causing the pain typical of ankle impingement. Thirteen patients were excluded from the initial sample, leaving a total of 207 patients for inclusion in final enrollment (Fig. Fig. For information on cookies and how you can disable them visit our Privacy and Cookie Policy. Among the 220 patients whose cases were ultimately reviewed, 201 underwent a standard three-view examination and 19 underwent a standard two-view examination. 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. [22], would be a more sensitive method of detecting peroneal tendon subluxation-dislocation. In: Ferkel RD ed. Therefore, early detection of impingement is beneficial for successful surgical results. MRI findings of subfibular impingement (n = 22) most commonly included low T1 and predominantly low T2 signal intensity soft-tissue entrapment between the calcaneus and fibula (n = 15, 68%) (Figs. 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. The location of marrow edema may be a helpful distinguishing feature. There were 28 cases (37%) with lateral hindfoot impingement. 2019 Nov;49(12):1691-1701. doi: 10.1007/s00247-019-04459-5.

RESULTS. M75.42 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. MATERIALS AND METHODS. This finding raises the possibility that distal fibular periostitis may be a previously un-described radiographic sign of chronic peroneal tendon subluxation-dislocation. 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].

Peroneal tendon dislocation has also been observed in patients with congenital calcaneovalgus deformity [33]. Fig. 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. Tearing of the superior peroneal retinaculum is a known cause of peroneal tendon subluxation-dislocation. This stripping of the SPR allows the peroneal tendons to slide out of the retromalleolar groove. There were no cases of peroneal tendon dislocation. There was no significant association between the presence of lateral malleolar bursa and hindfoot valgus impingement or hindfoot valgus severity. 1993;75:331341.

MeSH 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. Unable to load your collection due to an error, Unable to load your delegates due to an error. 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). 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]. 2012 Sep 5;94(17):1584-94. doi: 10.2106/JBJS.K.00926. 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. The os trigonum is an extra (accessory) bone that sometimes develops behind the ankle bone (talus). Together they form a unique fingerprint. The ankle MRI examinations were performed at either 1.5 T or 3 T with several MRI units throughout our institution under standard institutional protocol. Our study noted a significant association between peroneal tendon subluxation and moderate or severe hindfoot valgus as well as combined talocalcanealsubfibular impingement. 2001;83:849854.

MeSH B, 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). WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. The predominant pattern was cystic changes with surrounding marrow edema (n = 16, 80%). Therefore, the symptoms were suspected to have been caused only by fibulocalcaneal impingement owing to a relatively long fibula. HHS Vulnerability Disclosure, Help 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. 3. 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. Fisher's exact test was used to evaluate associations among these findings. Subfibular impingement has been described in patients with flatfoot. Mann RA, Mann RA. Lateral adventitial bursa was present in 11 of 28 patients (39%) with lateral impingement (Fig. 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]. Some error has occurred while processing your request. B, Anteroposterior (A) and oblique (B) radiographs of ankle show hindfoot valgus and periostitis along lateral cortical margin of fibular tip (arrowheads). 1A, 1B, 1C). This lateral ankle pain has been attributed to extraarticular lateral hindfoot impingement including talocalcaneal (between the lateral talus and calcaneus) [3, 4] and subfibular (between the calcaneus and fibula) impingement [511] (Fig. Subfibular impingement is one cause of extraarticular ankle impingement associated with lateral ankle pain and is typically associated with pes planovalgus Figure 1. 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]. An official website of the United States government. It is important to distinguish marrow edema involving the fibula in subfibular impingement from that related to a fibular stress fracture [29]. 2018 Dec;37(12):2753-2758. doi: 10.1002/jum.14633.

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. Would you like email updates of new search results? 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. 5A, 5B). 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. Agreement on hindfoot valgus measurement was interpreted as poor if the ICC was less than 0.4; fair, 0.4 to less than 0.6; good, 0.6 to less than 0.75; excellent, 0.75 and greater. Furthermore, patients with radio-graphic evidence of distal fibular periostitis were also significantly more likely to have MRI evidence of subfibular impingement than those without it.

Editorial Comment on "Fibular Tip Periostitis: New Radiographic Sign Predictive of Chronic Peroneal Tendon Subluxation-Dislocation in Pes Planovalgus". 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. Additional exclusion criteria included navicular posterior tibial tendon tear, prior posterior tibial tendon surgery, and incomplete or unavailable studies on our PACS. In stage II, there is a tear of the posterior tibial tendon with loss of normal alignment of the foot. Anteroposterior radiograph shows smooth periosteal reaction (arrows) along distal fibular diaphysis secondary to callus formation. A positive association was also seen between impingement and hindfoot valgus severity. 8600 Rockville Pike What is the extra bone in your ankle called? WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. WebSubfibular impingement is one cause of extraarticular ankle impingement characterized by pain in the lateral aspect of the hindfoot. The prevalence of impingement was significantly increased with greater MRI hindfoot valgus angle (p < 0.001). Investigations involving middle facet coalitions--Part II. Calcaneal osteotomy is often necessary to correct the hindfoot valgus and lateral hindfoot impingement [1]. We developed a grading scheme for hindfoot valgus severity based on MRI measurement of the coronal tibiocalcaneal angle. In contrast, stage III represents severe incompetence of the posterior tibial tendon and progression to a fixed flatfoot deformity. 4. Sural nerve neuroma . The blinded readers had substantial or almost perfect agreement on all imaging interpretations (concordance rate, 82.995.7%; = 0.660.91). 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. Odds ratios were calculated to assess the utility of distal fibular periostitis as a predictor of peroneal tendon subluxation-dislocation.

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. Ankle Ligaments on MRI: Appearance of Normal and Injured Ligaments, Superior Labral Anteroposterior Tear: Classification and Diagnosis on MRI and MR Arthrography, Review. Hindfoot valgus angle measurements were significantly greater in the periostitis group (30.7) than in the control group (25.7) (p = .007). Therefore, it is important for the radiologist to raise the possibility of peroneal tendon subluxation-dislocation, which according to our findings can be surmised by the presence of periostitis of the distal fibula. To the best of our knowledge, these relationships have not been described previously in the literature. Fig. All statistical tests were conducted at the two-sided 5% significance level with SAS software (version 9.4, SAS Institute).

Furthermore, combined talocalcanealsubfibular impingement was seen in a minority of cases with grade I posterior tibial tendon tears (12%), whereas a higher percentage was seen with grade II (33%) and grade III (57%) posterior tibial tendon tears. pes planus . Finally, periostitis related to callus formation in healing bone is easily recognized, because it centers on the site of fracture deformity (Fig. This may result in retromalleolar pain, lateral ankle instability, or popping and snapping sensations along the distal fibula [6]. Care should be taken to differentiate distal fibular periostitis secondary to hindfoot valgus from acute avulsion of the SPR and from other causes of distal fibular periosteal reaction, such as venous insufficiency, infection, and fracture (Fig. 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. WebSubfibular 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 Bilateral Triple Talocalcaneal, Calcaneonavicular, and Talonavicular Tarsal Coalition: A Case Report. It is possible that the proximity of the calcaneus to the fibula with advanced posterior tibial tendon dysfunction leads to crowding and subsequent displacement of the peroneal tendons of the retromalleolar groove. 5. 2008 Jul-Aug;47(4):288-94. doi: 10.1053/j.jfas.2008.04.004. 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.

The ROC analysis showed that the threshold value of 16 resulted in a diagnostic test with the highest average of sensitivity and specificity. fibular overgrowth; fibulocalcaneal impingement; growing child; position of distal fibular physis; talocalcaneal coalition. 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]. Foot Ankle Int. The authors thank James Babb for his assistance with statistical analysis. The patient then presented in 2016 with a complaint of lateral ankle pain, 5 of 10 in severity, with imaging consistent with subtalar nonunion as well as subfibular impingement . Extraarticular lateral hindfoot impingement is associated with advanced posterior tibial tendon tears and increased MRI hindfoot valgus angle. A, Anteroposterior radiograph shows distal fibular periostitis (arrowhead). For radiographic fibular periostitis, the readers were concordant on 95.7% of their interpretations, having almost perfect agreement ( = 0.91). Medial calcaneal sliding osteotomy is a surgical procedure designed to dramatically modify the existing shape of your foot, creating an arch to correct flat feet. Specifically, the images were evaluated for the presence of marrow edema, cystic changes, or sclerosis at the opposing osseous surfaces of the talus and calcaneus or the fibula and calcaneus and the presence of soft-tissue entrapment at those locations. Bookshelf Interreader agreement on these findings was assessed by calculation of Cohen kappa coefficients and concordance rates. WebAnkle impingement refers to a chronic painful mechanical limitation of ankle motion caused by soft-tissue or osseous abnormality affecting the tibiotalar joint or extraarticular soft The keyword search yielded the records of 220 consecutively enrolled adult patients with hindfoot valgus and both ankle radiographs and MRI examinations. The prevalence of impingement was significantly increased with greater MRI hindfoot valgus angle (p< 0.001). Bone Marrow 28%. 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]. 4A 54-year-old man with pes planovalgus, distal fibular periostitis, subfibular impingement, peroneal tendon dislocation, and peroneus brevis split tear. your express consent. 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%). Tenderness at the front of the ankle when touched. C, 50-year-old woman with distal fibular periostitis (not in study sample). Medical records were reviewed and the clinical details recorded included patient age, sex, involved side, and clinical indication for the MRI study. Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi. MRI features of talocalcaneal impingement (n = 20) included marrow edema (n = 20, 100%) or cystic changes (n = 19, 95%) (Figs. How its caused/treatment. 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. To the best of our knowledge, the MRI appearance of lateral hindfoot impingement has not been reported. Furthermore, both readers found that subfibular impingement was significantly more prevalent in the periostitis group (reader 1, 25/35 [71.4%]; reader 2, 20/35 [57.1%]) than in the control group (reader 1, 1/35 [2.9%]; reader 2, 0/35) (both readers, p < .001). Statistical analyses were performed using Cochran-Armitage, Fisher's exact, and Mann-Whitney tests. 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 finding of periostitis was specific and highly sensitive for predicting peroneal tendon subluxation-dislocation. CLINICAL IMPACT. 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. Foot function after subtalar distraction bone-block arthrodesis: a prospective study. Anterior Shoulder Instability in the Aging Population: MRI Injury Pattern and Management. 2 Flowchart depicts selection process for study. This video demonstrates one method of performing this procedure which resulted in dramatic pain improvement and functional restoration. This includes peroneus brevis to peroneus longus tendon transfer, in which weakening the lateral tendons compensates for loss of medial preservers of the longitudinal arch, and peroneal to posterior tibial tendon transfer, which is performed as a way to strengthen the posterior tibialis tendon [11, 12, 20]. and transmitted securely. Federal government websites often end in .gov or .mil. This patient group size was based on statistical power calculation. FOIA 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. 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. (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. Severe hindfoot valgus was present in a minority of patients (n = 14, 19%). Fig. MRI studies can help identify the size of peroneal tendon tear and identify concomitant injuries to nearby structures. Among the 24 patients with fibular periostitis and MRI evidence of impingement, 18 (75.0%) also had peroneal tendon subluxation-dislocation (Figs. 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]. RESULTS. Fibular tip periostitis proved to be both a specific and a highly sensitive indicator of peroneal tendon subluxation-dislocation. Impingement syndromes of the ankle and hindfoot. 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. Bethesda, MD 20894, Web Policies 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). 3B 61-year-old woman with hindfoot valgus, distal fibular tip periostitis, peroneus longus tendon subluxation, and subfibular impingement. We also thank James Babb for statistical analysis. Complications of iliac crest bone graft harvesting. Both fibular marrow abnormalities occur with increased frequency in hindfoot valgus and lateral impingement [12, 27]. However, this method may have introduced selection bias in study enrollment. Soft-tissue repair alone in patients with posterior tibial tendon dysfunction may lead to unsatisfactory surgical outcome and persistent lateral ankle pain. 5B 78-year-old man with hindfoot valgus, distal fibular tip periostitis, peroneal tendon dislocation, and subfibular impingement. 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. 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]. The typical indication for distraction arthrodesis is subtalar arthrosis in combination with loss of calcaneal height with or without subfibular impingement. Peroneal tendon subluxation was present only with advanced hindfoot valgus (p = 0.010) and impingement (p = 0.004).
