Paediatric foot deformities (treatment of flexible flat feet, sinus tarsi screw, arthroereisis)

In cases of flexible flatfoot in children, the most common treatment is a minor intervention involving a mini-titanium implant that can remain in the foot throughout their lifetime. Arthroereisis is frequently conducted for young patients with flexible flatfoot for whom conservative treatments have not been successful (subtalar arthroereisis). The malposition of the foot and misalignment of the heel bone (calcaneus) and ankle bone (talus) are corrected by blocking the lower ankle joint and making an insertion outside the articular capsule – usually in the sinus tarsi. For a patient to be eligible for this procedure, they must still have multiple years of their growth phase ahead of them so that the surrounding tendons and ligaments have time to develop properly.
