抄録 Thigh pain often appears after total hip arthroplasty (THA) using a cementless femoral component. It is known that sensory nerve endings exist in the medullary cavity of the bone. The purpose of this study was to investigate, in a rabbit model, whether the pressure on the femoral bone applied from inside the medullary cavity of the femoral bone causes flexion withdrawal reflex.
 We loaded pressure on the inside of the medullary cavity of the femoral bone and observed whether muscle activity occurs. The pain resulting from pressure was evaluated by hind limb flexor activity produced by the flexor reflex. An integrated waveform was used to evaluate the degree of muscle activity. For the laboratory-animal models, we prepared the medullary cavity of the rabbits in two ways. In the rabbits with slight reaming, the flexor reflex appeared in low pressure. However, in rabbits with greater reaming, the flexor reflex did not appear, even under high pressure. This suggests that the pain was induced when the sensory nerve endings remained in the inside of the medullary cavity of the femoral bone and the sensory nerve endings were stimulated by the stress.
