概要 Purpose
Foot deformities such as hallux valgus and flatfoot are common
problems that may require surgeries. The ideal foot shape must be
reconstructed in three dimensional (3D) orientation by adjusting
bones and soft tissues appropriately; otherwise, new foot problems
will be brought postoperatively as typified by transfer metatarsalgia
after hallux valgus surgery [1]. The types and amounts of bony or soft
tissue correction could be based on returning plantar pressures pattern
of known appropriate one. To evaluate correction, measurement of
plantar pressure in vertical posture is required. However, it is difficult
to estimate plantar pressure in standing posture during surgery since
the patient is in a supine position under anesthesia. We have proposed
a surgical assistance device that can measure plantar pressure under
physiological load state of the bones as if the patient is in the standing
posture during surgery (Intraoperative Plantar Pressure Measurement
(IPPM) device) [2]. We constructed a system to guide an operator to
align pushing plate on the patient foot in appropriate location and
orientation using surgical navigation technology. It was demonstrated
that the plantar pressure distribution can be reproduced similar to that
in the standing posture under the condition where the floor reaction
force passed near the center of the femoral head and the Center of
Pressure (CoP) that is defined as centroid of the applied pressure on
the foot was located similar to the CoP during the normal standing
posture.
