Tarsal coalition

Jason S Chu, Tyler Underriner, Arthur Yegorov
Tarsal coalition is a condition described by partial union between tarsal bones. Its clinical significance is the potential cause for chronic pain in the ankle and foot. Diagnosis of this condition may be delayed until adolescence or early adulthood, and is often made incidentally on examination for other purposes. Treatments for this condition can range from conservative options to surgical approach. The calcaneonavicular and talocalcaneal subtypes make up the majority of this condition, with involvement among other tarsal bones much rarer in comparison...

Proximal symphalangism (SYM1B) (OMIM 615298) is an autosomal dominant developmental disorder affecting joint fusion. It is characterized by variable fusions of the proximal interphalangeal joints of the hands, typically of the ring and little finger, with the thumb typically being spared. SYM1 is frequently associated with coalition of tarsal bones and conductive hearing loss. Molecular studies have identified two possible genetic aetiologies for this syndrome, NOG and GDF5. We herein present a British caucasian family with SYM1B caused by a mutation of the GDF5 gene...

Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination-external rotation injuries. Deltoid ligament injuries have a significant impact on lateral ankle instability but can be overlooked in patients with lateral ligament injuries. Posterior tibial tendon dysfunction is usually associated with spring ligament or flexor retinaculum injury. Tarsal tunnel syndrome, accessory flexor muscles, and subtalar coalition should be considered as well as ligament and tendon tears in differential diagnosis of chronic medial ankle pain...

Posterior ankle pain is a cause of chronic pain and disability, afflicting a wide range of individuals. While proper identification of the cause is essential for timely and adequate treatment, identifying the cause and excluding mimickers is often challenging for the physician due to the complex nature of the joint. In addition, pathology that can cause posterior ankle pain may occur on their own or in co-existence. Clinical conditions that can present as posterior ankle pain include: posterior ankle impingement, Achilles tendon pathology, medial flexor tendon pathology, peroneal pathology, retrocalcaneal bursitis, posterior subtalar tarsal coalition, sinus tarsi, and tarsal tunnel syndrome...

OBJECTIVE: To assess, utilizing MRI, tarsal tunnel disease in patients with talocalcaneal coalitions. To the best of our knowledge, this has only anecdotally been described before. MATERIALS AND METHODS: Sixty-seven ankle MRIs with talocalcaneal coalition were retrospectively reviewed for disease of tendons and nerves of the tarsal tunnel. Interobserver variability in diagnosing tendon disease was performed in 30 of the 67 cases. Tarsal tunnel nerves were also evaluated in a control group of 20 consecutive ankle MRIs...

The human noggin (NOG) gene is responsible for a broad spectrum of clinical manifestations of NOG-related symphalangism spectrum disorder (NOG-SSD), which include proximal symphalangism, multiple synostoses, stapes ankylosis with broad thumbs (SABTT), tarsal-carpal coalition syndrome, and brachydactyly type B2. Some of these disorders exhibit phenotypes associated with congenital stapes ankylosis. In the present study, we describe a Japanese pedigree with dactylosymphysis and conductive hearing loss due to congenital stapes ankylosis...

INTRODUCTION: There is still a controversial discussion on the treatment of talocalcaneal coalition with and without planovalgus deformity. From 2002-2014 80 cases of talocalcaneal coalition in children and adolescents under 18 years of age were surgically treated by J. Hamel. The objective of this study is a retrospective analysis, especially of unfavourable results. METHODS: Patients with minimum follow up of 12 months were included (35.7 months on average)...

PURPOSE: It has been the observation of the senior author that there is a bony fullness or "double medial malleolus" over the middle facet as a consistent finding with most talocalcaneal coalitions (TCC). To document this observation, we reviewed records and radiographs in 3 patient groups. METHODS: Part 1: retrospective chart review was completed for 111 feet to determine the clinical presence of a palpable "double medial malleolus." Part 2: computed tomography (CT) scans for evaluation of tarsal coalition or symptomatic flatfoot between January 2006 and December 2014 were retrospectively reviewed for the same cohort...

There has been a lot of hype surrounding the advantages to be gained from rapid prototyping processes in a number of fields, including medicine. Our literature review aims objectively to assess how effective patient-specific surgical guides manufactured using rapid prototyping are in a number of orthopaedic surgical applications. To this end, we carried out a systematic review to identify and analyse clinical and experimental literature studies in which rapid prototyping patient-specific surgical guides are used, focusing especially on those that entail quantifiable outcomes and, at the same time, providing details on the guides' design and type of manufacturing process...

Tarsal coalition (a congenital fibrous, cartilaginous, or bony connection between two bones) classically presents with recurrent ankle sprains or with insidious onset of a painful, stiff flatfoot. Flatfoot is a benign finding most of the time, but it is important to distinguish the rigid flatfoot from the flexible flatfoot. A patient with recurrent sprains of the ankle or a stiff flatfoot should be evaluated for a tarsal coalition. The key to making the diagnosis is careful examination for stiffness in the subtalar joint and appropriate imaging studies...

Tarsal coalition is relatively frequent, with an estimated prevalence of 1-2%. Coalitions are most commonly talocalcaneal or calcaneonavicular, accounting for 90% of cases. While it is well known that bilateral tarsal coalitions can occur in up to 50% of cases, the presence of multiple coalitions in the same foot is less well described. In this report, we present a case of talocalcaneal and calcaneonavicular coalitions occurring in the same foot and briefly review the relevant literature.

Flatfoot (pes planus) is common in infants and children and often resolves by adolescence. Thus, flatfoot is described as physiologic because it is usually flexible, painless, and of no functional consequence. In rare instances, flatfoot can become painful or rigid, which may be a sign of underlying foot pathology, including arthritis or tarsal coalition. Despite its prevalence, there is no standard definition for pediatric flatfoot. Furthermore, there are no large, prospective studies that compare the natural history of idiopathic, flexible flat feet throughout development in response to various treatments...

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...

Tarsal coalitions refer to fibrous, cartilaginous or osseous fusion between two tarsal bones. Commonly seen are talocalcaneal coalitions and calcaneonavicular coalitions. Talonavicular, calcaneocuboid and cubonavicular coalition are very uncommonly seen. Talocalcaneal and calcaneonavicular coalitions are generally symptomatic whereas talonavicular coalitions are asymptomatic. Special view radiography, CT and MRI will be helpful in diagnosing coalitions depending on nature of coalitions. In this case report, we present 24-year-old male patient with rare combination of talocalcaneal and talonavicular coalition on ipsilateral side...

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...

INTRODUCTION: Tarsal coalition is abnormal fusion of two or more tarsal bones and is a common cause of foot pain. There are osseous, cartilaginous and fibrous subtypes. Calcaneonavicular and talocalcaneal coalitions are more frequent. Radiography is the primary diagnostic tool, however CT and MRI are precious examinations for differential diagnosis of osseous /non-osseous coalitions separations. Furthermore, cross-sectional imaging methods indicate the extension and secondary degenerative joint changes...

Isolated navicular-medial cuneiform tarsal coalition is a rare condition. Very few case reports exist, with limited treatment recommendations. We present a case of an 11-year-old with bilateral isolated osseous navicular-medial cuneiform tarsal coalition. The patient was treated with bilateral coalition excision and soft tissue interposition, with excellent results at 2 years of follow-up. The current case is unusual in being an osseous coalition rather than the more commonly seen cartilaginous or fibrous condition...

BACKGROUND: Children with flatfeet are frequently referred to pediatric orthopaedic clinics. Most of these patients are asymptomatic and require no treatment. Care must be taken to differentiate patients with flexible flatfeet from those with rigid deformity that may have underlying pathology and have need of treatment. Rigid flatfeet in infants may be attributable to a congenital vertical talus (CVT); whereas those in older children and adolescents may be due to an underlying tarsal coalition...
