What is tarsal coalition?
Tarsal coalition refers to an abnormal connection of fibrous tissue between the tarsal bones of the feet. There are seven tarsals that comprise the mid and hind foot, located in the ankle, heel, and arch of the foot. The condition is associated with pain and reduced mobility in the feet, which can impact the patient's ability to perform many everyday functions.
Many tarsal coalitions are due to a genetic condition in which two or more bones fuse together during fetal development. In around half of cases, both feet will be affected. However, in some rare cases tarsal coalition occurs as a result of infection, injury or arthritis. Often, tarsal coalition results in a rigid flat foot, causing pain and, in some cases, having debilitating impacts on mobility.
Although infants are typically born with the condition, it is difficult to identify until the child's bones begin to mature. With this comes the onset of painful symptoms, usually in mid to late childhood. However, most children born with tarsal coalition will never develop symptoms and therefore do not require treatment.
