ABSTRACT
Background: A tarsal coalition is a bridging of two or more of the bones in the hindfoot. Multiple coalitions aredescribed in the literature. However, the presence of a tibio-talar coalition has not previously been reported.Results : Here, we describe the first reported case of tibio-talar and fibulo-talar coalition in the literature in a 31-year-old male. The patient had a 5-year history of bilateral hindfoot and ankle pain, with an established rightsided talo-calaneal coalition. Investigations and subsequent open chilectomy and debridement surgery confirmeda tibio-talar and fibulo-talar coalition. The patient was discharged at one-year following surgery as he was painfree and returned to work.Conclusions: We report the first case of failure of mesenchymal segmentation leading to tibio-talar fibrouscoalition and fibulo-talar coalition. In this case surgical debridement provided resolution of symptoms. Level ofClinical Evidence: 4
ABSTRACT
This paper reports a rare case of the symptomatic third metatarsal (MT3) - lateral cuneiform (LC) in a 55-year-old male who presented with complaints of severe intermittent pain in his right foot. Plain radiographs and computed tomography scans revealed sclerosis and irregularity at this joint. The intraoperative findings demonstrated a fibrocartilaginous coalition. The pain had improved one year after removing the MT3-LC joint by en bloc and arthrodesis.

PURPOSE: Tarsal coalition results from defects during the developmental stage and produes ankle pain and limitations in the range of motions. Its incidence has been reported to be 1%, but there has not been any reports with respect to Koreans. Therefore, we evaluated the prevalence of tarsal coalition in Koreans. MATERIALS AND METHODS: Between 2005 and 2014, we analyzed a total of 733 cases of foot and ankle magnetic resonance imaging (MRI) in our hospital. There were 391 men and 342 women. All MRI readings were read by a radiologist in our hospital. We classified the coalitions in accordance with the histological and anatomical characteristics, and calculated the prevalence in each group. Moreover, we tried to determine the prevalence of tarsal coalitions in accordance with sex, age, and proportion of the symptomatic tarsal coalitions. RESULTS: There were a total of 11 MRIs of tarsal coalition—9 talocalcaneal coalitions, 1 calcaneocuboidal coalition, and 1 calcaneonavicular coalition. Nine tarsal coalitions were observed in men and 2 in women. CONCLUSION: Through this study, we found that the prevalence of tarsal coalition, including the asymptomatic patients, is similar to the previously known prevalence (1%). By getting more MRIs of the foot and ankle, we could better represent the prevalence of tarsal coalitions in Koreans.

Abstract: The talonavicular coalition is a rare congenital anomaly of the foot, often associated with other malformations. Unlike other coalitions, most patients are asymptomatic and do not require surgery. The authors describe two cases of patients with talonavicular coalition, one bilateral and the other unilateral associated with other malformations. The sign of the mushroom is presented as a practical way to diagnose talonavicular coalition on a standing anteroposterior radiograph, in which the contours of the bone fusion mimic the shape of a mushroom. This sign will help radiologists in the proper diagnosis of this rare coalition.
Resumen: La coalición talonavicular es una anomalía congénita poco frecuente del pie, a menudo asociada a otras malformaciones. A diferencia de otras coaliciones, la mayoría de los pacientes son asintomáticos, y no requieren cirugía. Los autores describen 2 casos de pacientes con coalición talonavicular, uno bilateral y el otro unilateral, asociados a otras malformaciones. Presentamos el signo de la seta como una práctica manera de diagnosticar la coalición talonavicular en proyección anteroposterior del pie, en el cual los contornos de la fusión ósea remedan la forma de un hongo. Este signo será de ayuda a los radiólogos para el adecuado diagnóstico de esta rara coalición.

The tarsal coalition corresponds to the abnormal osseous, cartilaginous or fibrous joining between two or more bones in the midfoot or hindfoot. The anteater nose sign is caused by a tubular elongation of the anterior process of the calcaneus that approaches or overlaps the tarsal scaphoid (navicular) and resembles the nose of an anteater on a lateral foot or ankle radiograph.
La coalición tarsal corresponde a la unión anormal, ya sea ósea, cartilaginosa o fibrosa, entre dos o más huesos del retro o medio pie. El signo de la nariz del oso hormiguero es causada por un alargamiento tubular del proceso anterior del calcáneo que se acerca o se superpone con el escafoides tarsiano y se asemeja a la nariz de un oso hormiguero en una radiografía lateral del pie o tobillo.

A tarsal coalition is an abnormal union between 2 or more tarsal bones of the hind- and midfoot, which can be congenital or acquired. The documented overall incidence of tarsal coalition is 1% or less. The resulting abnormal articulation leads to accelerated degeneration within adjacent joint. Pain is often diffuse, exacerbated by strenuous activity or following an ankle sprain. The findings on physical examination is protruded mass, diminished range of motion of the involved joint. It is possible to identify of tarsal coalitions with conventional radiography, but CT scanning necessary to evaluate of the size, location, characteristic and preoperative planning of tarsal coalitions. The initial treatment for a tarsal coalition is conservative, but tarsal coalitions unresponsive to conservative treatment, are managed by coalition resection, or arthrodesis in case of presence of degenerative changes.
