Common tendon of the musculature of the anterior compartment of the leg

Clubfoot is a common pediatric condition with a variable etiology. Most commonly it is multifactorial with an uncertain cause. However, on occasion a definitive anatomical abnormality predisposes to the development of clubfoot. We present a case of a 3-year-old girl with clubfoot presenting with a full range of motion, but no active ankle or toe dorsiflexion despite anterior compartmental muscle contraction. The cause of this appearance was noted intraoperatively to be a common anterior compartment tendon, which was adhered to the distal tibia. This case presents an interesting anomaly that clinicians treating clubfoot should be aware of.
