“…There was no device used to bring the anterior pelvic plane parallel to the film as originally described by Lewinnek et al [9]. Thus, obliquity due to spinal deformities and pelvic tilt are not accounted for which might affect the measurement accuracy for cup version [29]. However, Lu et al [10] demonstrated that standard AP pelvic radiographs without the use of such a device allow for reliable and accurate measurements of acetabular orientation in relation to computed tomography (CT).…”

Purpose Limited data exist for the reconstructive potential of short bone-preserving stems in THA using a minimal invasive posterolateral approach. Our study aim was to assess the effect of stem design on the reconstruction of hip offset and leg length in MIS posterolateral THA. Methods This retrospective consecutive single-surgeon study compares hip offset and leg length, as well as acetabular component positioning (cup anteversion; inclination) of 129 THAs with a cementless standard-length stem (Synergy®) and 143 THAs with a cementless short bone-preserving stem (Trilock®). Results In reference to the contralateral side, the mean difference in hip offset was 0.9 mm (p=0.067) for the standard stem and 0.1 mm (p=0.793) for the short stem, respectively. Leglength discrepancy was 0.7 mm (Synergy®) and 0.9 mm (Trilock®), respectively. A total of 233 (86 %) acetabular components fell within the target zone for anteversion and inclination. Conclusion Accurate component positioning in MIS posterolateral approach THA is possible and is not influenced by the type of stem.

“…Several studies conducted by experienced surgeons at prominent institutions have looked at the accuracy of acetabular component position when using traditional methods utilizing mechanical guides and anatomic landmarks such as the anterior superior iliac spine and pubic symphysis [7] and transverse acetabular ligament [15,16]. In this setting, component position is dependent on the surgeon's interpretation of the position of the patient's pelvis on the operating table.…”

Fluoroscopy assessment during anterior minimally invasive hip replacement is more accurate than with the posterior approach

Using fluoroscopy in the direct anterior approach, we achieved better intra-operative assessment of cup orientation resulting in decreased variability of acetabular cup anteversion than when used in the posterior approach. At least some of the improvement was due to the fact that the fluoroscopic image in the supine position was more accurate as measured against the postoperative standing AP pelvis. This study may influence the choice of approach in total hip replacement.
