Tarsal Coalition

What is a Tarsal Coalition?

Understanding the condition

Tarsal coalition is a congenital foot condition in which two or more of the tarsal bones are joined by an abnormal bone connection made of bone, cartilage, or fibrous tissue. These fused foot bones restrict normal movement of the subtalar joint, leading to rigid flatfoot, painful flat feet, foot stiffness, and ankle stiffness. Many children do not develop symptoms until adolescence, when the bones mature, resulting in foot pain in teenagers, adolescent foot pain, or even recurrent ankle sprains. Early tarsal coalition treatment is important to relieve symptoms, improve mobility, and prevent progression of this congenital foot deformity.

How We Diagnose Tarsal Coalition

Diagnosis includes a physical examination to assess foot motion, alignment, and tenderness. X-rays are typically used to identify abnormal bone connections, while CT or MRI scans may be ordered for a detailed view of the coalition and surrounding structures.

How We Heal Tarsal Coalition

How is surgery performed?

Surgery may be considered if conservative treatment fails and the child has significant pain or restricted motion. Surgical options include: Simple excision: Removing the accessory navicular bone. Kidner procedure: Removing the extra bone and repositioning or repairing the posterior tibial tendon to restore proper function.
