What is the most common type of tarsal coalition?

• A. Talocalcaneal
• B. Calcaneonavicular
• C. Navicular-cuneiform
• D. Intermetatarsal

Answer: (B)

The most common type of tarsal coalition is calcaneonavicular coalition. This condition involves abnormal connections between the calcaneus (heel bone) and the navicular bone, leading to varying degrees of restriction in motion and potential pain in the foot. Calcaneonavicular coalitions are often diagnosed in childhood or adolescence, and they can manifest with symptoms such as flatfoot, pain, and stiffness. The presence of a coalition can impede normal joint movement and loading patterns, which can impact the biomechanics of the foot. In contrast, other types of tarsal coalition, such as talocalcaneal or navicular-cuneiform, are less frequently encountered. Talocalcaneal coalition involves the talus and calcaneus, while navicular-cuneiform coalition connects the navicular to the cuneiform bones. The intermetatarsal coalition pertains to connections among the metatarsal bones, but it does not directly involve the tarsal bones in a significant way. The higher incidence of calcaneonavicular coalitions in the population underscores its prominence as the most common type of tarsal coalition encountered in clinical practice. Understanding the prevalence and implications of this condition is crucial for podiatrists when diagnosing and
