Abstract
A Lower Leg Walker for the treatment of ankle fractures and a variety of other injuries to the foot and ankle, has a foot platform base comprising a rigid chassis of more or less parallelepiped shape. The chassis is substantially a plurality of ribs disposed at right angles, forming a grid and is over-moulded with resilient materials forming a shoe shape. The foot platform base supports and accommodates the human foot and has a distinctive, low, double rocker profile on its underside. The lower leg walker is provided with attachment hinges for securing a pair of upright side-members to the foot platform base and these are covered with hook and loop attachment material which releasably secures them to a wrap which is lined with terry material and encloses the foot, ankle and lower leg. The device is secured to the patient with a series of straps.
