Which treatment is indicated for Johnson and Strom Stage II flat foot deformity?

• A. FDL transfer to navicular
• B. Pan-talar fusion
• C. Subtalar joint fusion
• D. Orthotics and rest

Answer: (A)

In the context of Johnson and Strom Stage II flat foot deformity, the goal of treatment is to address the mechanical instability and the associated pain, while still maintaining some level of foot function. In Stage II, the condition is characterized by a flexible flat foot with some degree of functional loss, but the joints are still mobile. Transferring the flexor digitorum longus (FDL) tendon to the navicular is a surgical intervention used to restore the support and alignment of the foot. This technique helps in re-establishing the medial arch by providing a dynamic stabilizing force when the foot is in motion. The FDL tendon serves as a secondary tendon for the posterior tibial muscle, which is compromised in this deformity. By rerouting the tendon, it assists in flexing the toes while also providing support to the navicular, combating the flat foot deformity effectively in this stage. The other treatments may not be as suitable for Stage II. While pan-talar fusion and subtalar joint fusion are more invasive options typically reserved for more advanced stages of flat foot deformity or where there is significant arthritis, orthotics and rest may provide symptomatic relief but do not address the underlying mechanical instability effectively. Therefore, the most appropriate and
