Where would you place a scaphoid pad for a cavus foot?

Placing a scaphoid pad under the tuberosity of the navicular is the appropriate choice for a cavus foot. This type of foot is characterized by a high arch, and individuals often experience increased pressures and discomfort in the forefoot and midfoot regions. The navicular bone is a key structural component of the arch, and cushioning it with a scaphoid pad helps to absorb shock and redistribute pressure through the midfoot.

By positioning the pad here, it can support the natural alignment of the foot, alleviate discomfort, and help to stabilize the arch during ambulation. This correction is essential in addressing the overactivity of the foot's arch in cavus deformities, potentially preventing further complications such as metatarsalgia or strain injuries.

In contrast, the other locations for placing the pad each serve different effects and purposes which do not align with the needs of someone with a cavus foot. Effective treatment and support for a high-arched foot focus on areas that can directly influence the arch's stability and pressure distribution.
