First ray injuries.

The first ray differs from the other rays in its position and its importance with weight bearing. Because it is a critical structure in the formation of the tripod of the foot, injuries to this ray can cause critical alterations in the biomechanics of the foot. This allows for pathologic weight-bearing points of contact and deformity that lead to a disabling gait. Physicians who are involved in the care of the foot and ankle should be familiar with the spectrum of injuries that concern the first ray. These injuries, their management, and sequelae are reviewed.
