Pes Planus in Rigid Adult-Acquired Flatfoot Deformity

Rigid adult-acquired flatfoot deformity represents a fixed, structural collapse of the medial longitudinal arch that does not correct passively on examination. This specific presentation of pes planus warrants a targeted surgical approach distinct from flexible flatfoot management.

Clinical scenario

Pes planus presenting as a rigid adult-acquired flatfoot deformity — a fixed hindfoot malalignment where the arch does not reconstitute under load correction, making conservative realignment strategies insufficient.

Treatment approach (partial overview)

Surgical management focuses on hindfoot joint fusion, approached via a medial incision. The protocol specifies which joints are addressed and whether procedures are performed in combination or in isolation — the full sequencing, joint selection criteria, and surgical details are in the complete protocol.

Rigid flatfoot deformity may be effectively treated by talonavicular and subtalar joint fusion in combination or in isolation.

Medial incision approach does not increase risk of complication when performing hindfoot fusion.

The medial incision approach provides adequate visualization and surgical access to hindfoot joints when performing a modified triple arthrodesis.
