Background
The mechanism of offloading plantar pressure with a TCC is by redistributing weight-bearing load across the entire plantar surface of the foot and increasing the plantar surface contact area [1]. An additional mechanism is by transfer of load to the cast walls however these studies relied on indirect methods [2–4]. No previous research has directly measured the load on the cast wall.
The aim of this pilot study was to:
-
1.
Systematically map pressure between the walls of the TCC and the lower limb to identify those areas of greatest pressure.
-
2.
To directly measure load transfer from the plantar surface of the foot to the cast walls.
