Abstract
We used Laser Doppler flowmetry to measure the effect on the blood flow to the femoral head/ neck junction of two surgical approaches during resurfacing arthroplasty. We studied 24 hips undergoing resurfacing arthroplasty for osteoarthritis. Of these, 12 had a posterior approach and 12 a trochanteric flip approach. A Laser probe was placed under radiological control in the superolateral part of the femoral head/ neck junction. The Doppler flux was measured at stages of the operation and compared with the initial flux. In both groups the main fall in blood flow occurred during the initial exposure and capsulotomy of the hip joint.
There was a greater reduction in blood flow with the posterior ( 40%) than with the trochanteric flip approach ( 11%).
