Where is the appropriate placement for a scaphoid pad on a cavus foot?

The appropriate placement for a scaphoid pad on a cavus foot is indeed under the tuberosity of the navicular. This area is clinically significant because the scaphoid bone, which is located in this region, plays a crucial role in foot biomechanics. Cavus foot, characterized by an excessive arch, can lead to an imbalance in load distribution across the foot, often resulting in discomfort or instability.

Placing the scaphoid pad under the tuberosity of the navicular helps in several ways. It provides support to the medial midfoot, redistributing weight and improving alignment, which can enhance stability during movement. The pad also facilitates better shock absorption, leading to a reduction in pressure on areas that are typically overloaded in cavus foot types.

Placement in other areas, such as under the cuboid notch, under the 1st ray, or under the calcaneal cuboid, would not effectively address the specific needs associated with cavus foot. Each of those locations does not provide the same level of support and realignment needed for the midfoot, which is critical to managing the higher arches and preventing potential complications associated with cavus foot.
