Which orthosis is designed to support the longitudinal arch of the foot?

• A. Scaphoid Pad
• B. Lateral heel wedge
• C. Medial/ lateral sole wedges
• D. Rocker Bar

Answer: (A)

The scaphoid pad is designed to support the longitudinal arch by directly elevating and supporting the plantar navicular/scaphoid area. Placed under the scaphoid tuberosity, it helps maintain arch height during weight bearing, which reduces navicular drop and excessive pronation in flexible flat feet. The other options modify foot mechanics without providing direct arch support: a lateral heel wedge mainly changes subtalar motion for varus/valgus control; sole wedges adjust forefoot-to-rearfoot alignment but don’t elevate the arch; a rocker bar facilitates forward progression rather than supporting the arch itself. So, the scaphoid pad best fulfills the goal of supporting the longitudinal arch.
