Abstract
Cubonavicular coalition is a rare congenital anomaly involving fibrous or osseous fusion between the cuboid and navicular bones. This case report presents a comprehensive analysis of a 10-year-old female patient with cubonavicular coalition, detailing the diagnostic challenges and tailored therapeutic interventions. The patient presented with persistent left foot pain and restricted range of motion. Clinical examination, radiographic studies, and magnetic resonance imaging confirmed cubonavicular coalition. Laboratory investigations ruled out systemic inflammatory processes. A multidisciplinary approach was adopted, initially employing nonsteroidal anti-inflammatory drugs and physical therapy. Surgical resection of the coalition was performed due to persistent symptoms, leading to successful outcomes. This case report contributes valuable insights into the clinical presentation, diagnosis, and management of cubonavicular coalition in pediatric patients. The successful outcome underscores the importance of a comprehensive and individualized approach, providing a basis for informed decision-making in similar cases. Continued research is essential to refine therapeutic algorithms and enhance understanding of rare musculoskeletal anomalies.

Resection of Bar in the Management of Calcaneonavicular Coalition: A Systematic Review. Cureus 2023; 15:e39275. [PMID: 37346201 PMCID: PMC10279521 DOI: 10.7759/cureus.39275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/20/2023] [Indexed: 06/23/2023] Open
Abstract
The most commonly encountered type of tarsal coalition in symptomatic patients is the calcaneonavicular coalition. Non-surgical treatments are effective for most patients. However, if surgery is required, excision of the calcaneonavicular bar can be a successful option that preserves hindfoot mobility and function. We conducted a systematic review of calcaneonavicular bar excision in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) checklist. To conduct the review, we conducted a thorough search of several databases, including PubMed, Cochrane, Excerpta Medica Database (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Google Scholar, and bibliographies. We analyzed the chosen studies to collect information on patient demographics, clinical outcomes, surgical techniques, and potential complications. We identified 11 studies that included 274 patients for a total of 394 feet. The average age of patients in these studies was 12.5 years, ranging from 8.2 to 19.4 years. Follow-up periods varied from 2.3 to 23 years, with an average duration of 5.9 years. Excision of the calcaneonavicular bar was performed at 380 feet, while fusion was performed at 14 feet. In 50.5% of the feet, the extensor digitorum brevis was used as an interposition material. Successful outcomes after bar excision were observed in 82.9% of cases (304 feet) and were described as satisfactory, improved, good, or excellent outcomes. In one study, the American Orthopaedic Foot and Ankle Society (AOFAS) score improved from 47.89 to 90.22 in 12 feet after bar excision. Recurrence was reported in 52 feet out of the 380 feet that underwent bar excision. Progression of arthritis in the ankle and subtalar joint was reported in 25 feet. Various complications were reported, including paraesthesia in the hindfoot (three feet), midfoot pain (three feet), hindfoot pain (two feet), mild wound infection (one foot), and swelling and stiffness (one foot). Surgical excision of the calcaneonavicular bar has shown successful outcomes in most patients, regardless of the use of interposition material. These outcomes are associated with minimal and acceptable complications. However, since the studies conducted in the literature were single-center retrospective and prospective trials, a multicenter prospective study with patient-centered, validated outcomes would provide a better opportunity to support the evidence in favor of surgical excision of the calcaneonavicular bar. Overall, the use of various interposition materials is associated with reduced chances of recurrence compared to cases where no interposition material was used.

A retrospective magnetic resonance imaging analysis of bone and soft tissue changes associated with the spectrum of tarsal coalitions. Clin Anat 2023; 36:336-343. [PMID: 35384073 DOI: 10.1002/ca.23866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2022] [Revised: 03/27/2022] [Accepted: 03/28/2022] [Indexed: 11/10/2022]
Abstract
We aimed to investigate the bone and soft tissue changes accompanying tarsal coalition (TC) and aimed to evaluate their association with the location and type of coalition. Ankle magnetic resonance imagings of 65 patients with TC were included. The relationship between the location and type of coalition and bone marrow edema, subchondral cysts, sinus tarsi syndrome, tarsal tunnel syndrome, posterior impingement syndrome, accessory bone, tibiotalar effusion, talar osteochondritis dissecans, ganglion cysts, and calcaneal spur were evaluated. Twenty-nine patients without coalition were selected as the control group, and the distribution of these variables between the two groups was analyzed. There were 33 females and 32 males in the coalition group (mean age: 42.0 ± 15.63 years), and 22 females and seven males in the control group (mean age: 44.79 ± 12.33 years). Coalition was most common in the talocalcaneal joint (n = 33, 50.8%), and the most common coalition type was non-osseous (n = 57, 87.6%). We find no significant difference between the pathologies defined in terms of coalition location and type. Sinus tarsi syndrome, tarsal tunnel syndrome, subchondral cysts, and tibiotalar effusion were found to be more common in the coalition group (p = 0.028, p = 0.010, p = 0.023, and p = 0.006, respectively). The presence of coalition increased the probability of developing tarsal tunnel syndrome 9.91 times (95% CI: [1.25-78.59]; p = 0.029), and sinus tarsi syndrome 3.66 times (95% CI: [1.14-11.78]; p = 0.029). Tarsal coalition may predispose bone and soft tissue changes. In this study, sinus tarsi syndrome, tarsal tunnel syndrome, subchondral cysts and tibiotalar effusion were found to be more common in the coalition group.

Fracture through Pre-Existing Tarsal Coalition: A Narrative Review. CHILDREN (BASEL, SWITZERLAND) 2022; 10:children10010072. [PMID: 36670623 PMCID: PMC9857168 DOI: 10.3390/children10010072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Revised: 12/21/2022] [Accepted: 12/27/2022] [Indexed: 12/31/2022]
Abstract
Tarsal coalitions are abnormal fibrous or bony connections between the tarsal bones of the foot. While not always symptomatic, coalitions can cause pain, alterations in forefoot and hindfoot morphology, and alterations in foot and ankle biomechanics. Previous research has described the association of tarsal coalitions with fractures of the lower extremity. Multiple reports of acute fracture in the presence of tarsal coalition have been presented, as have reports of stress fractures of the foot and ankle with concomitant coalition, insidious in onset and thought to be related to aberrancies in foot and ankle biomechanics. The purpose of this review is to discuss the biomechanics seen in tarsal coalitions and to describe reports of fracture occurring concomitantly with tarsal coalitions. We will discuss diagnostic options and treatment approaches in the setting of fracture with preexisting tarsal coalition.

Abstract
OBJECTIVE This study describes the radiographic diagnosis and nonoperative chiropractic management for a case of a chronic calcaneonavicular coalition in an adult patient. BACKGROUND Calcaneonavicular coalition is a congenital/acquired condition of the tarsal bones often diagnosed in individuals 8-12 years old. Considering its rare presentation (less than 1% of the population), there remains little literature on the conservative management of this condition. CASE PRESENTATION Chronic calcaneonavicular coalition in a 35-year-old recreational athlete is presented. MANAGEMENT/OUTCOME Following radiographic diagnosis, the patient was placed in a walking boot for four-weeks. After removal of the boot, the patient was managed nonoperatively. They reported a full resolution of symptoms with noted return to all pre-injury activities. SUMMARY Presentation of calcaneonavicular coalition may be dependent on many factors, including age, medical history, and chronicity of the condition. Previous medical background may include recurrent inversion ankle sprains, aggravated with activity, and alleviated with rest. Nonoperative management of calcaneonavicular coalition may be considered as a viable intervention.

Pseudomyogenic Hemangioendothelioma of the Talocalcaneal Coalition: A Case Report. J Foot Ankle Surg 2021; 60:1073-1078. [PMID: 34127373 DOI: 10.1053/j.jfas.2021.04.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 12/05/2020] [Accepted: 04/04/2021] [Indexed: 02/03/2023]
Abstract
Pseudomyogenic hemangioendothelioma is a rare soft tissue tumor most often found in the lower extremities and predominantly occurring in males. The talocalcaneal coalition is an anatomic anomaly that develops between the talus and calcaneus bones, can cause hindfoot pain and subtalar joint stiffness, and has a prevalence of less than 1%. We present what is to our knowledge the first case report of a 17-year-old male with pseudomyogenic hemangioendothelioma occurring within a talocalcaneal coalition. The patient was treated with local excision of the tumor and the coalition. His American Orthopaedic Foot & Ankle Society ankle/hindfoot score went from 70 preoperatively to 92 at 1 year postoperatively, and he has had no evidence of recurrence at 1 and 3 years postoperatively. These tumors have suggestive but not diagnostic computed tomography, magnetic resonance imaging, and histopathological findings, and they are associated with a uniquely characteristic immunophenotype, including immunochemical reactivity to CD31, FLi-1, INI-1, ERG, and FOSB. Primary treatment of pseudomyogenic hemangioendothelioma most often involves local excision (but can require amputation) and may include adjuvant radiotherapy and/or chemotherapy. It has a relatively favorable prognosis, with a moderate risk of local recurrence and a low risk of metastases. Because metastases have been reported many years after treatment, long-term follow-up is necessary.

Abstract
Tarsal coalition is a condition characterized by abnormal connections between ≥2 tarsi. Although tarsal coalition is not rare, tarsal coalitions involving >2 tarsi are very unusual. In this report, we describe a case of multiple tarsal coalitions in a 24-year-old male who experienced progressively worsening pain for 3 to 4 months before presenting for care. This case was unique in that all the tarsal and tarsometatarsal bones in the foot were fused and formed 1 integrated tarsal. All of the metatarsals were fused as well, and the patient had no joints or ranges of motion in the hindfoot or midfoot. The patient's pain was responsive to anti-inflammatory medications, and no surgical intervention was necessary. To the best of our knowledge, this is the most extensive case of multiple tarsal coalitions described in the literature to date.

Abstract
PURPOSE Tarsal coalitions are congenital fusions of two or more tarsal bones and can lead to foot pain and stiffness. Few studies examine the long-term reoperation rates following paediatric tarsal coalition surgery. METHODS A population-based database, linking medical records at all medical centres to capture the entire medical history of the full population of a Midwest county, was used to identify tarsal coalitions in children between 1966 and 2018. Records were reviewed for clinical data, surgical records and followed up to identify any subsequent surgical interventions. RESULTS A total of 58 patients (85 coalitions) were identified; 46 calcaneonavicular (CN) coalitions, 30 talocalcaneal (TC) coalitions and nine other coalitions (seven talonavicular, one naviculocuboid, one naviculocuneiform). In all, 46 coalitions were treated surgically (43 coalition resections, three arthrodeses) and 39 were treated nonoperatively. Patients treated surgically were less likely to report ongoing symptoms at final follow-up compared with patients managed nonoperatively (33% versus 67%; p = 0.0017). With a median 14.4 years (interquartile range 9.3 to 19.7) follow-up, there was an overall re-operation rate of 8.7% (4/46). Differences in reoperation rates by initial surgery (resection versus arthrodesis; p = 0.2936), coalition type (CN versus TC versus Other; p = 0.6487) or composition (osseous versus fibrocartilaginous; p = 0.29) did not reach statistical significance. CONCLUSION This is the first population-based study demonstrating the durability of surgical management of tarsal coalitions in a paediatric population. At final follow-up, patients treated surgically are less likely to report persistent symptoms compared with patients managed nonoperatively. Long-term reoperation rates appear to be low (8.7%).

Cryopreserved Amniotic Membrane and Autogenous Adipose Tissue as an Interpositional Spacer After Resection of a Cubonavicular Coalition: A Case Report and Review of the Literature. J Foot Ankle Surg 2020; 59:173-177.

Abstract
Coalitions of the hindfoot are a relatively rare but challenging condition encountered by foot and ankle surgeons. Those that manifest between the cuboid and navicular (cubonavicular coalitions) are seen even more infrequently and are estimated to comprise ∼1% of all tarsal coalitions. Treatment for cubonavicular coalitions parallels protocols for more common hindfoot coalitions. Typically, resection versus hindfoot arthrodesis procedures are used. The present study describes the case of a 34-year-old male with a painful cubonavicular coalition and early secondary signs of arthrosis. Despite the recommended guidelines of hindfoot arthrodesis, he elected for surgical resection. Autogenous adipose tissue and cryopreserved amniotic membrane were used for interposition at the resection site. This case demonstrates that surgical resection with interpositional grafting can be successful even in advanced disease states.

Abstract
PURPOSE We aimed to determine the factors that influence the symptoms of naviculo-cuneiform (NC) coalition using radiography and computed tomography (CT). METHODS We retrospectively reviewed the radiographic and CT findings of 37 NC coalition cases. The existence of a large pit (depth >3 mm), irregular articular surface, joint space narrowing, dorsal bony spur, subchondral sclerosis, multiple subchondral bony cysts, and intra-articular loose body were evaluated on radiographs or CT. The size of the largest subchondral bony cyst was also measured using CT. All cases were divided into two subgroups according to the symptoms. Fisher's exact test was used to distinguish the factors influencing the symptoms. RESULTS Twenty-three and fourteen feet were enrolled into the symptomatic and asymptomatic groups, respectively. The rates of the large pit on either radiograph (47.83 vs. 21.43%) or CT (65.22 vs. 28.57%) were significantly different between both groups ( p = 0.001). The mean size of the largest subchondral bony cyst on CT was also significantly greater in the symptomatic group (4.25 vs. 1.53 mm, p = 0.005). CONCLUSION A large deep pit and huge subchondral bony cyst on the radiograph or CT can be related to symptoms for the patient with NC coalition. A CT is highly recommended for a more accurate evaluation in patients with NC coalition.

Abstract
A tarsal coalition is an abnormal connection between two or more tarsal bones caused by failure of mesenchymal segmentation. The two most common tarsal coalitions are calcaneonavicular coalition (CNC) and talocalcaneal coalition (TCC). Both CNC and TCC can be associated with significant foot and ankle pain and impaired quality of life; there may also be concomitant foot and ankle deformity. Initial, non-operative management for symptomatic tarsal coalition commonly fails, leaving surgical intervention as the only recourse. The focus of this article is to critically describe the variety of methods used to surgically manage CNC and TCC. In review of the pertinent literature we highlight the ongoing treatment controversies in this field and discuss new innovations. The evidence-based algorithmic approach used by the authors in the management of tarsal coalitions is illustrated alongside some clinical pearls that should help surgeons treating this common, and at times complex, condition.

Abstract
Few studies have evaluated the long-term functional and radiological outcomes of tarsal coalition resections. This study aimed to report and compare the functional and radiological outcomes after talocalcaneal (TC) and calcaneonavicular (CN) coalition resections. Thirty-three patients between 12 and 35 years old with symptomatic tarsal coalitions participated, each undergoing tarsal coalition resections (24 TC and 9 CN). The range of motion, visual analog scale score, American Orthopedic Foot and Ankle Society hindfoot scale, Maryland foot score, tripod index, and modified Kellgren-Lawrence scale for subtalar osteoarthritis were used to evaluate the functional and radiological outcomes. The mean age at the time of surgery and mean follow-up in the TC group were 17.8 ± 5.6 years (range 13 to 35) and 6.2 ± 1.7 years (range 5 to 12), respectively, and 16.0 ± 4.4 years (range 12 to 23) and 7.7 ± 3.0 years (range, 5 to 12) in the CN group. There was no difference in the range of motion, outcome scores, tripod index score, and modified Kellgren-Lawrence scale score between patients in the 2 groups. A positive correlation was noted between the size of the TC coalition, coalition/joint surface ratio, and hindfoot valgus angle regarding outcome scores. However, there was no association between the modified Kellgren-Lawrence scale score and outcome scores. At the minimum 5-year follow-up, the functional and radiological outcomes were similar between TC and CN resections. Subtalar joint osteoarthritis developed in all patients with TC resections and most patients with CN resections, but patients did not have functional impairment.

Identification of a Novel NOG Missense Mutation in a Chinese Family With Symphalangism and Tarsal Coalitions. Front Genet 2019; 10:353.

Abstract
Background Proximal symphalangism (SYM1) is a rare genetic bone disorder characterized by the fusion of proximal interphalangeal joints in the hands and feet. Genetic studies have identified two genes underlying SYM1 as the noggin (NOG) and the growth differentiation factor 5 (GDF5). Case Report In the present report, a 43-year-old gravida at 11 weeks of gestation was referred for evaluation of abnormal fusions of the joints. In the initial diagnosis, physical examination was undertaken. However, traditional radiological examination was not applied due to the need to protect the fetus, making diagnosis results inefficient to determine the exact disease affecting the proband. To acquire alternative clinical evidences, we conducted radiological examinations on two other affected family members. The radiological examination revealed that they carried the symphalangism accompanied with tarsal coalition, a very rare manifestation of SYM1. A combination of whole exome sequencing (WES) and Sanger sequencing revealed a novel heterozygous missense mutation (c.163G > T; p.Asp55Tyr) in the NOG gene, which could be associated with the observed pathogenic SYM1 in the studied family. The p.Asp55Tyr mutation co-segregated with SYM1 through the affected and unaffected family members. In silico structural modeling of the p.Asp55Tyr mutation showed that it abolishes the interaction with the Arg167 residue and causes a change in the electrostatic potential profile of the type II binding site of the noggin protein. Conclusion Our findings indicate that the genetic test based on WES can be useful in diagnosing SYM1 patients, with particular advantages in preventing the fetus from contacting harmful X-ray through the traditional radiography. The novel pathogenic mutation identified would further expand our understanding of the mutation spectrum of NOG in association with SYM1 disease and provide a guidance on how to determine whether the fetus is affected by SYM1 through the prenatal diagnosis.

Abstract
Subtalar coalitions are a significant cause of morbidity, especially in the pediatric population. Arthrodesis was considered the standard of care, with coalitions involving >50% of the joint until the mid-1990s. Today, some are recommending resection of the coalition first and to save hindfoot arthrodesis as a salvage procedure. As a result, resection of talocalcaneal coalitions is becoming more common, and optimizing the surgical technique is a necessity in the field of orthopedics. We present a technique to optimize surgical resection of talocalcaneal coalitions by using Kirschner wires inserted from the lateral side, which allows us to demarcate the coalition. This gives us a greater ability to perform a more complete resection and also helps prevent iatrogenic trauma to the articulating surface.

Abstract
It has been proposed that patients with talocalcaneal and talonavicular coalitions have decreased ankle joint range of motion. It has also been reported that rotational forces regularly absorbed by the talocalcaneal joint are transferred to the ankle joint in patients with coalitions, increasing the stress on the ankle joint after trauma. To the best of our knowledge, only 1 reported study has detailed the increased stress placed on the ankle joint secondary to a coalition. We present a case study of a 53-year-old female who experienced a traumatic fall and subsequent right ankle fracture. Advanced imaging studies revealed a comminuted tibial pilon fracture and talocalcaneal and talonavicular joint coalitions. She underwent open reduction and internal fixation for treatment of the fracture, and the coalitions were not treated because they were asymptomatic. She was kept non-weightbearing for 6 weeks postoperatively and was returned to a regular sneaker at 10 weeks postoperatively. The postoperative films revealed stable intact fixation and pain-free gait with no increased restriction in her ankle joint range of motion. The hardware was removed at 13 months postoperatively. She had not experienced increased pain or arthritic changes at 15 months postoperatively.

Abstract
The ball-and-socket ankle joint is a rare deformity characterized by the loss of concavity in the trochlear surface of the talus with rounding of the articular surfaces of the distal fibula and tibia. Frequently, tarsal coalitions, fibular hypoplasia, and shortening of the limb accompany this deformity. To date, no data have been reported on surgical treatment of lateral ankle joint instability and peroneal tendon dislocation concomitant with a ball-and-socket ankle joint. In the present study, we report the case of a 43-year-old male patient with right lateral ankle joint instability and peroneal tendon dislocation in a ball-and-socket ankle joint, with accompanying tarsal coalition. This was surgically treated by lateral ankle joint ligament reconstruction and tenodesis.

Abstract
INTRODUCTION Recommendations for the initial treatment (nonoperative measures to surgical excision) of symptomatic tarsal coalitions vary. Because nonoperative outcomes are poorly established, we retrospectively evaluated their success in preventing surgery and achieving pain relief for pediatric patients with symptomatic tarsal coalitions. MATERIALS AND METHODS A retrospective study of pediatric patients with symptomatic tarsal coalitions treated at a single institution was undertaken. Clinical notes were examined for treatment methods, response to treatment, and need for additional procedures. A statistical analysis was performed using the chi-square and Mann-Whitney U tests. RESULTS Fifty symptomatic tarsal coalitions (mean patient age, 11.4 years; range, 8.1-17.9) were treated with nonoperative measures. Surgery was not required in 79% of calcaneonavicular and 62% of talocalcaneal coalitions. Pain relief was achieved in 53% of 81 nonoperative treatment trials. Continuous immobilization via casting, intermittent immobilization via walking boot, and supportive measures were not significantly different in pain relief (p = 0.35) or preventing surgery (p = 0.62). CONCLUSION Nonoperative treatment methods have the potential to achieve pain relief and prevent or delay surgery for symptomatic tarsal coalitions. However, some families may elect to forgo nonoperative measures knowing that surgery may eventually be required.

Talocalcaneal tarsal coalitions are a common source of foot pain, stiffness, and deformity. These coalitions are treated symptomatically with rest and periods of immobilization. When those measures fail, surgical resection is attempted. This procedure is an anatomic challenge with the consequence of leaving residual coalition. The residual coalition primarily results from difficulty with intraoperative imaging because fluoroscopy does not provide adequate detail of this area. Some investigators have recommended intraoperative computed tomography after resection with reasonable results. We describe the combination of an intraoperative computed tomography with a navigated instrument system for resection of talocalcaneal coalitions. The use of a navigated probe and burr aids in defining the most anterior, posterior, and medial extents of the coalition. This technique reduces the morbidity, with less bone removed and preservation of intact subtalar articulations and allows for an efficient, thorough, and controlled resection.

Abstract
Postaxial limb hypoplasia (PALH) is a group of nonhereditary diseases with congenital lower limb deficiency affecting the fibular ray, including fibular hemimelia, proximal femoral focal deficiency, and tarsal coalition. The etiology and the developmental biology of the anomaly are still not fully understood. Here, we review the previous classification systems, present the clinical features, and discuss the developmental biology of PALH.

Abstract
Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score). Blinded analysis of the preoperative CT scan findings determined the presence of a standard MF versus a PMST coalition. The perioperative factors and postoperative outcomes between the MF and PMST coalitions were compared. A total of 51 feet (36 patients) were included. The mean follow-up duration was 2.6 years after surgery. Of the 51 feet, 15 (29.4%) had a PMST coalition and 36 (70.6%) had an MF coalition. No difference was found in the UCLA activity score; however, the mean AOFAS scale score was higher for patients with PMST (95.7) than for those with MF (86.5; p = .018). Of the patients with a PMST, none had foot pain limiting their activities at the final clinical follow-up visit. However, in the group with an MF subtalar coalition, 10 (27.8%) had ongoing foot pain limiting activity at the final follow-up visit (p = .024). Compared with MF subtalar tarsal coalitions, patients with PMST coalitions showed significantly improved clinical outcomes after excision. Preoperative identification of the facet morphology can improve patient counseling and expectations after surgery.

Abstract
UNLABELLED Tarsal coalition is a bony or fibrous bridge between 2 tarsal bones. The condition is typically congenital and presents in early to mid-adolescence. Common symptoms include ankle pain, stiffness, and limited range of motion. Conservative treatment of tarsal coalition consists of immobilization, short leg walking cast, steroid injections, physical therapy, ankle braces, and orthotics. When conservative care fails, surgical intervention for tarsal coalition includes excision of the coalition or joint arthrodesis. We present a case of a high school football player with a 5-year history of left ankle pain secondary to a talocalcaneal coalition. The athlete did not respond favorably to conservative treatment and underwent a subtalar joint arthrodesis. Prior to surgery, the athlete consented to self-reported functional outcome measures, range of motion measures, and 3D video gait analysis to evaluate the effects of surgery. Measurements were taken prior to surgery and 1½ years after surgery. Clinically significant improvements were seen in subjective outcome measures and functional ankle range of motion in this case. There is limited research available to validate long-term outcomes for current conservative and surgical treatments of tarsal coalition. In this case, joint arthrodesis resulted in a good long-term outcome for this athlete. LEVELS OF EVIDENCE Therapeutic, Level IV: Case study.

Abstract
Tarsal coalitions are an abnormal union between 2 tarsal bones. They occur most commonly between the calcaneus and talus or the calcaneus and navicular but can also arise from other joints in the foot. Isolated cases of coalitions between the medial cuneiform and navicular are extremely rare, and only a few cases have been reported. Treatment recommendations are, therefore, sparse, and no long-term follow-up data have been reported. We present the case of 2 sisters, each diagnosed with a symptomatic naviculocuneiform coalition. To our knowledge, this is the first reported case in 2 first-degree relatives. Both sisters were involved in sports and presented with pain during physical activities. After conservative treatment had failed, they were both treated successfully with surgical excision of the coalition and arthrodiastasis, followed by a progressive return to activities. At the last follow-up examination at 5 and 3 years postoperatively, they remained pain free and fully involved in college soccer, making excision of a naviculocuneiform coalition with arthrodiastasis a valid treatment in the young athletic population.

Abstract
We describe a rare case of a nonosseous coalition of the lateral cuneocuboid joint with peroneal spasm that we successfully treated with resection. A 60-year-old female had been experiencing constant pain in her right foot, particularly when walking and going up and down stairs. The pain had been present for approximately 1 year after she had experienced a minor injury. Her right ankle showed plantar flexion restrictions (right 20° and left 40°) and was held in an antalgic valgus position. Sudden passive plantar flexion produced pain behind the lateral malleolus of the right ankle. Tenderness was detected in the right peroneus brevis tendon and the right sinus tarsi. On plain radiographs, the oblique view showed an irregularity in the articular surface of the lateral cuneocuboid joint in both feet. On computed tomography images, there was no osseous continuation in the lateral cuneocuboid joint, indicative of a nonosseous bridge between the lateral cuneiform and the cuboid. The nonosseous coalition between the lateral cuneiform and the cuboid was resected and the trabecular surfaces and cortical margins covered with a thin film of bone wax. The patient's recovery was unremarkable, and 1 year after surgery, she was able to walk without pain and was able to perform her usual activities and job.

Abstract
Calcaneonavicular coalition is a congenital anomaly characterized by a connection between the calcaneus and the navicular. It can manifest as lateral foot pain, peroneal spastic flatfoot, and repeated ankle sprains. Surgery is required in the case of chronic pain and after failure of conservative treatment. The aim of surgical intervention is pain relief and preventing recurrence. Arthroscopic resection is a minimally invasive alternative that has the advantages of quicker recovery and better aesthetic results. This technique has shown significant symptomatic improvement and no recurrence at early follow-up points in a small number of reported cases. The present report presents the case of a child with bilateral calcaneonavicular coalition. This is the first report to our knowledge that describes the outcome of simultaneous bilateral arthroscopic resection of calcaneonavicular coalition in a child with a 2-year follow-up period.

Abstract
A 17-year-old girl with bilateral ball-and-socket ankles reported left medial heel pain. Her left heel had gone into a varus position on tiptoeing, and a painful clunk had occurred when returning to normal standing. The clunk persisted after physiotherapy and treatment with an orthosis. Subtalar arthroscopy and peroneal tendoscopy showed mild diffuse synovitis of the ankle joint, especially over the posterior capsule, and a patch of inflamed and fibrotic synovium at the posterolateral corner of the subtalar joint. The clunk subsided immediately after arthroscopic synovectomy and had not recurred during 5 years of follow-up. We found no other reported cases of ankle and subtalar synovitis occurring in patients with a ball-and-socket ankle joint.

Abstract
BACKGROUND Tarsal coalitions affect up to 13% of the population and can be a cause of chronic ankle and hindfoot pain. They can be subdivided as osseous, cartilaginous, or fibrous types, each with unique radiographic, CT, and MR imaging findings. In particular, MR imaging offers the unique ability to determine the exact type of tarsal coalition that is present as well as whether any associated soft tissue abnormalities are present. QUESTIONS/PURPOSES The purposes of this paper were to (1) review the anatomy of the hindfoot; (2) review the radiographic, CT, and MR imaging findings of tarsal coalitions; and (3) review the imaging appearance of the specific types of tarsal coalitions. METHODS Online searches were performed using Google Scholar with the search criteria of "tarsal coalition," "hindfoot anatomy," and "subtalar coalition," and limiting the searches to papers published in the last 10 years in major radiology journals. RESULTS The anatomy of the hindfoot is complex but essential to understand. There are various radiographic, CT, and MR imaging findings that can be consistently noted in cases of tarsal coalition. The specific types of tarsal coalition demonstrate characteristic imaging findings. CONCLUSIONS Knowledge of the normal anatomy of the foot, in particular the hindfoot, combined with the knowledge of the imaging characteristics of different histologic subtypes of coalitions (osseous, cartilaginous, and fibrous) is essential for interpreting radiographic, CT, and MR images of the ankle and foot.

Abstract
BACKGROUND Naviculo-first cuneiform coalition is a rare form of tarsal coalition with few reports. We therefore have analyzed its clinical features and the results of treatment. METHODS We analyzed 36 feet in 28 patients diagnosed with naviculo-first cuneiform coalition from January 2003 to December 2010. The 28 patients were 10 males and 18 females, with 18 right and 18 left feet, including 8 patients with bilateral coalition. The location and morphological pattern of naviculo-first cuneiform coalition were analyzed radiologically. Symptomatic patients initially received conservative management for 6 months. Six feet of 5 patients were treated operatively, 3 feet by curettage and 3 by fusion. RESULTS Eighteen feet had symptoms, while 18 feet without symptoms were diagnosed incidentally. Mean patient age at diagnosis was 34.6 years (range, 10-68 years). The mean age at diagnosis of symptomatic patients was 29.6 years (range, 10-50 years). Coalitions were located mainly in the medioplantar area. There was no bony coalition. Computed tomography or magnetic resonance imaging showed a cystic pattern in 7 patients, an irregular pattern in 4, a combined pattern in 5, and a spur-forming pattern in 1. The mean American Orthopaedic Foot & Ankle Society scores at the last follow-up in patients treated conservatively and operatively were 95.3 (range, 87-100) and 83.5 (range, 70-95), respectively. Among the 5 operated patients, 3 patients (60%) complained of pain, including 2 who received curettage and 1 who developed a nonunion after attempted fusion. CONCLUSION Conservative treatment should be considered over surgery in treating naviculo-first cuneiform coalition. LEVEL OF EVIDENCE Level III, comparative case series.

Abstract
Peroneal spastic flatfoot is an uncommon condition. It often presents as a rigid and usually painful valgus deformity in the hindfoot with peroneal muscles spasms. Although tarsal coalition is an important cause, a few patients have not undergone bone coalitions. We describe a 27-year-old female who experienced recurrent peroneal spastic flatfoot after an injury. She was treated successfully with a combination of botulinum toxin type A and immobilization of the foot in a neutral position with a cast. After 3 years, the condition had not recurred, and she was pain free and walked normally, with no increase in muscle tone. This unique treatment could be of potential use to treat many patients with such conditions.

Abstract
BACKGROUND There are few long-term studies evaluating tarsal coalition resections. The purpose of this study was to compare patient outcomes following resection of calcaneonavicular (CN) and talocalcaneal (TC) bars and to determine the relationship between the extent of a coalition and the outcome of resection. METHODS Patients younger than 18 years receiving resection for symptomatic tarsal coalition (1991-2004 inclusive) were eligible to participate. Follow-up evaluation included clinical examination to assess range of motion and self-reported functional outcome questionnaires. Two validated functional scales were used: the American Academy of Orthopaedic Surgeons (AAOS) Foot and Ankle Module, and the Foot Function Index (FFI). Twenty-four patients with 32 tarsal coalition resections (19 CN and 13 TC feet) were included in this study. For CN and TC patients, the mean age at the time of surgery was 11.8 ± 1.1 and 11.9 ± 2.5 years, and the mean age at follow-up was 27.1 ± 1.1 and 25.0 ± 2.5 years, respectively. RESULTS Inversion and eversion were significantly less for TC feet when compared with CN (P = .03 and P = .01, respectively). No difference was noted between the CN and TC groups with respect to outcome scores. Furthermore, no association was noted between the size of TC coalition or hindfoot valgus angle with respect to outcome scores. CONCLUSION Resected CN and TC bars behaved similarly in the long term in terms of function and patient satisfaction. Favorable results were attained when resections were performed on TC coalitions that were greater than 50% of the posterior facet and hindfoot valgus angles greater than 16 degrees. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
This case reports an adolescent athlete with activity related chronic bilateral dorsal foot pain and stiffness. A 15 year old competitive female basketball player presented to a chiropractor subsequent to an unsuccessful course of conservative treatment for posterior tibial dysfunction. The patient's plain films were incorrectly read as normal and a CT scan obtained by the radiologist called the findings bilateral osteoarthritis. The patient was awaiting a referral to a rheumatologist at the time of initial consultation with the chiropractor. Examination revealed limited subtalar mobility and review of the images revealed bilateral non-osseous talocalcaneal coalition. The patient was subsequently directed to a pediatric orthopedic surgeon and is scheduled for a resection of the coalition. Primary care practitioners should be aware of this uncommon, but not rare, variable clinical presentation as misdiagnosis and mismanagement could lead to suboptimal patient outcomes. To our knowledge this is the first case report of a patient with tarsal coalition published in chiropractic literature. In addition, this case is the first to report radiographic evidence of chronic mechanical stress to the second metatarsal associated with tarsal coalition.
