Final answer:
A tarsal coalition usually happens in childhood or adolescence, typically between the ages of 10 and 16 during the ossification process of the tarsal bones.
Step-by-step explanation:
A tarsal coalition refers to an abnormal connection that develops between two bones in the back of the foot (the tarsal bones). This condition usually becomes evident during childhood or adolescence.
Especially, a TC coalition, which often involves the talus and calcaneus bones, typically presents symptoms in patients between the ages of 10 and 16, coinciding with the ossification process of these bones in adolescence.
Most cases are discovered when children or teenagers present with symptoms such as foot pain, a flatfoot deformity, or a limp.
Treatment for tarsal coalition can range from conservative methods such as rest, orthotic devices, and physical therapy, to more invasive approaches like corticosteroid injections or surgical intervention, depending on the severity and the response to initial treatment.
