An incidental talonavicular coalition in a diabetic patient: a podiatric perspective

Bilateral Multiple Tarsal Coalitions (Talonavicular and Talocalcaneal Coalitions) with Recurrent Ankle Sprain in an Adolescent

Tarsal coalition is defined as an abnormal bony, cartilaginous, or fibrous union of two or more tarsal bones. The incidence of tarsal coalition is approximately 2% in the general population. Talocalcaneal and calcaneonavicular coalitions are the most common. The talonavicular coalition is a rare entity with an incidence of approximately 1.3% among patients with tarsal coalitions. We present a case of a 12-year-old girl who had talonavicular and talocalcaneal coalitions associated with a recurrent ankle sprain. The talonavicular coalition was asymptomatic, and the talocalcaneal coalition was the cause of ankle pain and recurrent sprain. Surgical resection of the talocalcaneal coalition led to successful clinical and functional outcomes. In conclusion, the possibility of multiple tarsal coalitions should be considered in tarsal coalition patients, and the talocalcaneal coalition should be considered as a differential diagnosis in an adolescent patient with a recurrent ankle sprain.

Incidental discovery of isolated talonavicular coalition: Report of two cases

Tarsal coalitions may cause altered foot biomechanics leading to patient disability from osteoarthritis and other sequelae. While some types of coalition are common, isolated talonavicular coalitions are relatively rare. We present two cases of osseous talonavicular coalition that were incidentally discovered in adults and were most likely asymptomatic. Talonavicular coalition may have a hereditary component and may be associated with other anomalies, but many seem isolated, asymptomatic, and incidental.

Talonavicular Coalition as a Cause of Foot Pain

Tarsal coalitions have an incidence of 2% and are often underdiagnosed. These are considered to be one of the causes of chronic ankle and foot pain. Among all tarsal coalitions, the talonavicular type represents a rare and uncommon condition. The purpose of this article was to present the case of a 35-year-old male patient with a bilateral talonavicular coalition treated conservatively. A review of the literature was also performed to understand the management of this rare condition.
