cuboid navicular Tarsal Coalition in an adolescent female athlete
Journal of Bone and Joint Surgery American Volume, 2015Co-Authors: Tomoaki Kamiya, Kota Watanabe, Atsushi Teramoto, Toshihiko YamashitaAbstract:Case: A fourteen-year-old female shot-putter developed midfoot pain with activity that initially responded to nonoperative care. However, the symptoms subsequently returned and became persistent. Advanced imaging demonstrated a fibrous cuboid-navicular Tarsal Coalition. Surgical resection of the Tarsal Coalition was performed when the patient was seventeen years old, and she returned to sports activities postoperatively with no pain. Conclusion: Although fibrous cuboid-navicular Tarsal Coalition is a very rare condition, it should be considered as one cause of persistent midfoot pain in an adolescent athlete. Surgical resection of the Tarsal Coalition can lead to a resolution of symptoms.

congenital Tarsal Coalition multimodality evaluation with emphasis on ct and mr imaging
Radiographics, 2000Co-Authors: Joel S Newman, Arthur H NewbergAbstract:Congenital Tarsal Coalition is a diagnosis that is often overlooked in young patients who first present with foot and ankle pain. Calcaneonavicular and talocalcaneal Coalitions are encountered most frequently; fusion at other sites is much less common. Tarsal Coalitions may be osseous, cartilaginous, or fibrous. Calcaneonavicular Coalitions are readily detected on oblique radiographs. Radiographic confirmation of talocalcaneal Coalition is more difficult than for fusion at other locations, although several secondary radiographic signs may indirectly suggest the diagnosis. Computed tomography (CT) and magnetic resonance (MR) imaging are invaluable for assessment of Tarsal Coalitions because they allow differentiation of osseous from nonosseous Coalitions and because they depict the extent of joint involvement as well as secondary degenerative changes, features of vital importance in surgical planning. Short-inversion-time inversion recovery MR images may reveal bone marrow edema along the margins of the ab...

effects of Tarsal Coalition resection on dynamic plantar pressures and electromyography of lower extremity muscles
Journal of Foot & Ankle Surgery, 2005Co-Authors: Roger LyonAbstract:The goal of this study was to evaluate kinetic abnormalities in feet after Tarsal Coalition resection using plantar pressure measurements and electromyography of 4 muscle groups in the lower limb. Eleven subjects (14 feet) with Tarsal Coalition (3 feet with calcaneocuboid, 6 feet with calcaneonavicular, and 5 feet with talocalcaneal) underwent Coalition excision. Patients ranged in age from 9 to 17 years, and mean follow-up was 20 months. Two feet underwent subsequent subtalar fusion and 1 had a triple arthrodesis. Plantar pressure and electromyography measurements were compared with data taken from 68 normal (control) subjects between the ages of 6 to 16 years. Feet with Tarsal Coalition showed significant differences in the midfoot region, with increases in contact area (40.36 cm 2 ± 14.7 vs 18.02 cm 2 ± 8.0, P 2 sec ± 3.4 vs 1.83 N/cm 2 sec ± 0.9, P 2 ± 5.8, 6.81 N/cm 2 ± 2.8, P = .01). Tarsal Coalition feet also displayed reduced peak pressure and loading at the region of the fifth metaTarsal head as compared with uninvolved feet ( P

dynamic plantar pressure measurements in children with Tarsal Coalition
Pacific Conference on Computer Graphics and Applications, 2000Co-Authors: Roger LyonAbstract:Tarsal Coalition is a congenital foot anomaly seen in childhood. It results in a rigid flatfoot deformity. Radiographic studies are needed to confirm the diagnosis. Characterization of this foot deformity during normal gait was done using the Emed plantar pressure system (Novel Electronics Inc, St Paul, USA). The hindfoot demonstrated higher than normal peak pressure and increased peak pressure on the third metaTarsal area with an increased plantar contact area on the midfoot. The center of pressure line had a normal trajectory.

Tarsal Coalition an unusual cause of foot pain clinical spectrum and treatment in 129 patients
Seminars in Arthritis and Rheumatism, 1991Co-Authors: Craig W Carson, William W Ginsburg, Marc D Cohen, Richard A Mcleod, Harold B KitaokaAbstract:Abstract Tarsal Coalition is an unusual cause of foot symptoms. The abnormal fusion of Tarsal bones is caused by a congenital failure of mesenchyme to differentiate and form joints in the majority of cases. Symptoms from Tarsal Coalition generally present in the second decade of life when the congenital Coalition ossifies and becomes immobile. Patients describe pain and stiffness of the foot and reduced subtalar motion, local tenderness, and pes planus may be found on examination. In the adolescent, symptoms from Tarsal Coalition are readily recognized, but the diagnosis is frequently delayed in older patients. This is possibly due to physician unawareness that Coalition causes foot symptoms in older patients and to overlooking the Coalition on plain film radiography. Tarsal Coalition has an age-related distribution. The diagnosis should be considered in the patient with chronic foot pain, subtalar stiffness with or without a pes planus deformity.

Correlation between the accessory anterolateral talar facet, bone marrow edema, and Tarsal Coalitions
Skeletal Radiology, 2020Co-Authors: Josephina A. Vossen, Mashya Abbassi, Yanjun Qian, Curtis W. Hayes, Peter J Haar, Kevin B HooverAbstract:Objective The purposes of this study was to determine the prevalence of the accessory anterolateral talar facet (AALTF); to evaluate the relationship between AALTF, focal abutting bone marrow edema (FABME), and sinus tarsi edema; and to study the prevalence of Tarsal Coalitions in patients with the AALTF utilizing ankle MR images. Materials and methods 5-T ankle MR images were reviewed for the presence of AALTF, FABME, sinus tarsi edema, Tarsal Coalition, and location and type of Coalition (cartilaginous, fibrous, and osseous). Multivariate analysis was performed to examine the correlation between AALTF and the other variables. Results Three hundred ninety-one consecutive patients were included (age range 5–86 years; mean age 45 years). An AALTF was present in 3.6% (14/391) of patients. The AALTF prevalence was 2% in women and 6.6% in men. There was a significantly association between AALTF and FABME (9/14, p < 0.05), sinus tarsi edema (13/14, p < 0.05), and Tarsal Coalition (4/14, p < 0.05). Conclusion AALTF is relatively often detected on MRI of the ankle and significantly associated with BME, sinus tarsi edema, and subtalar Coalition. Patients with a Tarsal Coalition should be evaluated for the concurrent presence of an AALTF.
