“…Associated neurologic abnormalities can be divided into two broad categories: central nervous system defects or neuromuscular disorders. Though the remainder of vertical talus cases were once thought to be idiopathic in nature, there is increasing evidence for a genetic cause as many families demonstrate an autosomal dominant inheritance pattern [5,[12][13][14] (Table 1).…”

“…Coleman proposed two types of vertical talus, the first with isolated talonavicular dislocation and the second with both talonavicular and calcaneocuboid joint dislocations [34]. Ogata and Schoenecker [5] divided vertical talus into three groups. In group one, which is defined as idiopathic, there are no other associated diagnoses.…”

“…However, unlike casting for clubfoot [38], serial casting for congenital vertical talus has not been used until recently as a method of achieving definitive correction [39]. Instead, cast treatment for congenital vertical talus has been traditionally used as a method of improving the deformity and thereby decreasing the complexity of an inevitable extensive soft-tissue release operation [1,5,31,40].…”

“…It is characterized by a fixed dorsal dislocation of the navicular on the talar head and neck [2] resulting in a rigid flatfoot deformity. It occurs as an isolated deformity (idiopathic) in approximately half of all cases and is associated with neuromuscular and genetic disorders in the remaining cases [1,[3][4][5]. Fifty percent of children have bilateral involvement and there is no sex predilection [1].…”

Congenital vertical talus is an uncommon foot deformity that is present at birth and results in a rigid flatfoot deformity. Left untreated the deformity can result in pain and disability. Though the exact etiology of vertical talus is unknown, an increasing number of cases have been shown to have a genetic cause. Approximately 50% of all cases of vertical talus are associated with other neuromuscular abnormalities or known genetic syndromes. The remaining 50% of cases were once thought to be idiopathic in nature. However, there is increasing evidence that many of these cases are related to single gene defects. Most patients with vertical talus have been treated with major reconstructive surgeries that are fraught with complications such as wound necrosis, talar necrosis, undercorrection of the deformity, stiffness of the ankle and subtalar joint, and the eventual need for multiple operative procedures. Recently, a new approach to vertical talus that consists of serial casting and minimal surgery has resulted in excellent correction in the short-term. Longer follow-up will be necessary to ensure maintenance of correction with this new technique. A less invasive approach to the correction of vertical talus may provide more favorable long-term outcomes than more extensive surgery as has been shown to be true for clubfoot outcomes.

Purpose Congenital vertical talus (CVT) appears as an idiopathic or non-idiopathic deformity. In this study, we analysed the talar axis-first metatarsal base angle (TAM-BA) values of idiopathic and non-idiopathic CVT cases treated with the Dobbs method. Materials and methods Between January 2007 and July 2012, 20 cases of CVT were treated, starting with a manipulation, casting and a minimally invasive surgical approach. We analysed retrospectively the TAMBA values in idiopathic and non-idiopathic CVT. As a new indicator for the mobility in the talonavicular complex, we used the difference of the TAMBA in neutral position and the TAMBA in plantarflexion. TAMBA measurements of CVT successfully treated with the Dobbs method were compared to TAMBA values of CVT unsuccessfully treated using a minimally invasive approach. Results Out of 20 CVT, 14 were successfully treated with the Dobbs method. Of these 14, five feet were non-idiopathic and nine feet were idiopathic. Six feet did not have complete correction following the Dobbs protocol, and were associated with arthrogryposis or caudal regression syndrome. The initial TAMBA in idiopathic feet ranged from 70 to 110°(mean 88°). The TAMBA in non-idiopathic feet ranged from 75 to 128°(mean 105). Feet successfully treated with the Dobbs method had an initial TAMBA between 74 and 110°(mean 87°). Feet unsuccessfully treated with the Dobbs method had an initial TAMBA between 95 and 128°(mean 118°).The measurement difference between the TAMBA in neutral and plantarflexion positions in cases unsuccessfully treated with the Dobbs method were smaller compared to values of feet successfully treated with the Dobbs method. These differences were statistically significant (p \ 0.0001). Conclusion In our series, the success of the Dobbs method in CVT treatment depended on the flexibility in the talonavicular complex. The TAMBA value and TAMBA difference (TAMBA neutral minus TAMBA plantarflexion) express the flexibility in the talonavicular joint and could be predictive for the success of a minimally invasive treatment. Only in a few cases is the success of the Dobbs method limited. These feet are associated with a TAMBA greater than 120°in neutral position and, particularly, a TAMBA difference smaller than 25°.

Congenital vertical talus (CVT) is a primary dislocation of the talonavicular joint that often occurs in neuromusculoskeletal syndromes, but may also be seen as an isolated abnormality. Six families with isolated CVT were ascertained. DNA was isolated from 21 affected individuals and 17 unaffected individuals from these families, as well as from five sporadic patients with CVT. Variable expressivity was noted in three families, manifesting as clubfoot in three individuals. Genome-wide linkage analysis generated a maximum two-point logarithm of odds score on chromosome 2q with D2S1353 (Z max ¼ 1.43 at y max ¼ 0.1), 17 Mb from the HOXD gene cluster. DNA from one affected individual of each family was subjected to mutational analysis of the HOXD10 gene. A single missense mutation was identified (M319K, 956T > A) in the homeodomain recognition helix of the HOXD10 gene that segregated with disease in one large British family. This mutation was recently described in a family of Italian descent with CVT and Charcot-Marie-Tooth deformity HOXD10 gene mutations were not identified in any of the other families or sporadic patients with CVT, suggesting that genetic heterogeneity underlies this disorder. ß
