Fig. 3From: Effects of lower limb and pelvic pin positions on leg length and offset measurement errors in experimental total hip arthroplastyLeg length and offset measurement errors in relation to flexion-extension. The limb is moved from 30° flexion to 30° extension. P1, pelvic pin position in the iliac tubercle; P2, pelvic pin position in the iliac crest in line with the longitudinal axis of the femur; LL, leg length; OS, offsetBack to article page
