“…A fourth case of incidental finding was described by Chu [24], after a pilon fracture, but it is unclear whether or not the patient was symptomatic from the coalition. Interestingly, these three asymptomatic patients [21][22][23] were in their forties (mean and median 45 years old), while symptomatic patients [16][17][18][19][20][25][26][27][28][29][30][31][32][33][34][35] were younger (mean age 23 years old, median 17 years old). The analysis of the cases of the literature for cubonavicular coalition revealed that symptoms were more frequent for nonosseous (14/16, 88%) than osseous (7/9 cases, 78%) union but the small number of cases does not allow any assertion.…”

Introduction. Cubonavicular coalitions represent a relatively rare condition with less than forty cases described in the literature, the majority of which are fibrocartilaginous. To our knowledge, cubonavicular osseous coalition associated with osteoarthritis of the midfoot has never been described. Case Presentation. We present the case of a 26-year-old man with bilateral Achilles tendinosis, in whom radiological studies show an incidental finding of a complete osseous cubonavicular coalition, as well as a partial osseous cubo-third cuneiform coalition and a fibrous band between the first and second cuneiforms of the right foot, associated with arthritic changes of the tarsometatarsal joint. A nonosseous calcaneocubonavicular coalition was found on the left foot. These multiples coalitions were asymptomatic in this case. Discussion. Cubonavicular coalition, even asymptomatic, can cause midfoot osteoarthritis in young patients. We may therefore suspect that the immobility of the cubonavicular joint causes additional stress on the midfoot.

“…Talocalcaneal and calcaneo-navicular coalitions account for over 90% of cases and talo-navicular and calcaneo-cuboid coalitions for approximately 1% each. However, coalition between the cuboid and navicular is rare, with few reported cases in the literature [1,[5][6][7]. Conventional radiography is often sufficient for the diagnosis of more common tarsal coalitions, with a number of characteristic secondary radiographic signs described including the classical 'anteater nose' sign seen in calcaneo-navicular coalition.…”

DiscussionTarsal coalition is a congenital abnormality in which there are varying degrees of fusion between one or more bones in the foot. Reported to occur in 1-2% of the population, it is thought to result from a failure of mesenchymal separation during the first 8 weeks of embryonic development leading to failure of tarsal separation. A cartilaginous bridge persists between the tarsal bones, which can ossify spontaneously during maturation or because of activity-related mechanical stress. As a result, tarsal bridging coalition can be cartilaginous (synchondrosis), fibrous (syndesmosis) or osseous (synostosis) [1,2].The lateral surface of the navicular bone is rough and irregular, affording attachment of the cubo-navicular ligament, which also attaches to the dorsal and posteromedial surfaces of the cuboid. Usually, the anteromedial surface of the cuboid provides an articulating facet for the lateral cuneiform, but frequently there is an additional articulation with the navicular, divided from the lateral cuneiform articulation by a small vertical ridge. Similarly, the rough lateral surface of the navicular can provide an articulating facet for the cuboid bone [3]. Coalition of this articulation results in rigidity and potentially altered morphology of the hindfoot, commonly manifesting as a congenital flatfoot deformity. The altered biomechanics and rigidity of this deformity can result in a variety of extraarticular soft tissue and osseous ankle impingement syndromes, potentially progressing to early onset degenerative arthritis [4].Tarsal coalition is often asymptomatic but usually presents in adolescence as a painful foot, exacerbated by exercise. Talocalcaneal and calcaneo-navicular coalitions account for over 90% of cases and talo-navicular and calcaneo-cuboid coalitions for approximately 1% each. However, coalition between the cuboid and navicular is rare, with few reported cases in the literature [1,[5][6][7]. Conventional radiography is often sufficient for the diagnosis of more common tarsal coalitions, with a number of characteristic secondary radiographic signs described including the classical 'anteater nose' sign seen in calcaneo-navicular coalition. Clues to the existence of less common coalitions may also be seen with plain film such as subtle posterior facet irregularity in cases of posteromedial subtalar coalition [8]. Non-osseous or rarer coalitions may require cross-sectional imaging for diagnosis. MR imaging should be performed in three planes, with at least one fat-suppressed sequence to identify bone marrow oedema. Osseous coalitions will show marrow bridging across the coalesced articulation and the joint space will often be reduced. Cartilaginous bridges return signal similar to articular cartilage and fibrous coalitions return intermediate-to-low signal intensity. Fat-suppressed fluid-sensitive sequences may show marrow oedema along the fused articulation [1].We present a patient with an insidious onset of pain in his left foot, which was particularly severe following exercise or work...

“…ТК класифікують за локалізацією, протяжністю зрощення, видом тканини аномального зрощення та клінічними проявами [1,3,4]. За локалізацією розрізняють позасуглобові ТК, до яких зараховують п'ятково-човноподібну та кубоподібно-човноподібну коаліції; внутрішньосуглобові, серед яких виділяють таранно-п'яткову коаліцію, за якої можливе злиття середньої, задньої або передньої фасетки; та комбіновані ТК, такі як таранно-човноподібна, човноподібно-кли-ноподібна, п'ятково-кубоподібна [1][2][3][4].

Tarsal coalitions (TC) are congenital abnormal connections of the rearfoot bones. They occur in 1 to 13 % of all population. The article deals with the features of clinical and instrumental diagnosis of TC according to the literature. The main clinical manifestations are pain syndrome in the subtalar area, rigid flat foot; peroneal spastic flat foot is possible. Radiographic imaging of TC includes direct and indirect signs. To verify bone coalition, computed tomo-graphy is indicated, in cases of cartilaginous and fibrous — magnetic resonance imaging. Despite the long history of studying the problem, the diagnosis of TC remains a live issue today. Difficulties in diagnosing this pathology are due to the lack of physicians’ awareness of the clinical and radiographic picture of TC. Classical orthopedic exa-mination and suspicion of possible TC will allow detecting pathology in time and avoiding inappropriate treatment. The use of modern imaging techniques, such as computed tomography and magnetic resonance imaging, helps increase the accuracy of TC diagnosis.
