“…Various methods of measuring limb length change during surgery include comparing the dimensions of the resected bone with the dimensions replaced by the prosthesis [12,57,58], comparing the distance between the center of the trial head and the lesser trochanter [30,43], the use of mechanical jigs and measuring calipers [6,22,37,44], or the use of reference pins driven into the pelvis [3,21,31]. Some surgeons advocate the use of computer-assisted methods [33,41,55]. We did not compare preoperative and postoperative LLDs.…”

“…These problems can lead to revision surgery and may even be a source of litigation. Despite new implant designs, instrumentation and surgical techniques, limb length discrepancy still remains a concern for patients and surgeons [4,14,28,34].…”

“…For example, a femur malpositioning in 10°abduction and 10°flexion would result in an apparent error of 17.4 mm in LL [23]. Techniques using pins or jigs that are fixed some distance away from the bone surface exaggerate these effects of rotational error because the measurements are made away from the rotational center of the joint [28].…”

“…Previous studies suggest measuring solely the distance between fixed points on the pelvis and on the operative leg with navigation systems can cause substantial errors in the measurement of LL and OS change through inaccurate femur repositioning with respect to the pelvis during prereconstruction and postreconstruction assessments [15,18,23]. For example, a femur malpositioning in 10°abduction and 10°flexion would result in an apparent error of 17.4 mm in LL [23].…”
