“…This information allows the surgeon to realize the ‘Kinematic alignment technique’. As Rivière et al say 17-18 ‘this technique aims at restoring the native combined femoral acetabular anteversion and the hip’s centre rotation occasionally adjusting the cup position and design based on the assessment of the individual spine modification’. The transverse acetabular ligament (TAL) is the reference to adjust the cup position.…”

Preoperative planning is mandatory to achieve the restoration of a correct and personalized biomechanics of the hip.The radiographic review is the first and fundamental step in the planning. Limb or pelvis malpositioning during the review results in mislead planning.Correct templating is possible using three different methods: acetate templating on digital X-ray, digital 2D templating on digital X-ray and 3D digital templating on CT scan.Time efficiency, costs, reproducibility and accuracy must be considered when comparing different templating methods. Based on these parameters, acetate templating should not be abandoned; digital templating allows a permanent record of planning and can be electronically viewed by different members of surgical team; 3D templating is intrinsically more accurate. There is no evidence in the few recently published studies that 3D templating impacts positively on clinical outcomes except in difficult cases.The transverse acetabular ligament (TAL) is a reliable intraoperative soft tissue reference to set cup position.Spine–hip relations in osteoarthritic patients undergoing hip joint replacement must be considered.Cite this article: EFORT Open Rev 2019;4:626-632.

“…However, the precise definition of an optimal ‘safe‐zone’ and the most reliable method for its determination continues to be debated. A mounting body of evidence suggesting there is not one generic ideal zone 6,8–10 . Furthermore, accuracy of traditional freehand acetabular positioning techniques is unreliable, 8 with suboptimal positioning as high as 53%, highlighting the inaccuracy of traditional techniques 11 .…”

“…[17][18][19][20][21] The importance of functional positioning of the acetabular component relative to individual spinopelvic mobility has been recognized. [8][9][10]22 The wide variability in functional arc of pelvic motion from 5 to 70 must be considered for optimal acetabular positioning, especially in HR. 9,10,[23][24][25][26] Functional positioning plans are created for a standard THA acetabular positioning; 6,7 therefore, adjustments need to be considered in relation to HR positioning.…”

Malpositioning of metal‐on‐metal hip resurfacing can have catastrophic outcomes. Edge loading especially, in addition to rim impingement and deformation of the acetabular component, can result in bearing failure and metallosis and pseudotumours from cobalt and chromium metal debris. This study has confirmed that the use of functional positioning in hip resurfacing results in improved precision and accuracy in achieving functional acetabular ideal zones. Overall the use of functional navigation in hip resurfacing has achieved both improved clinical outcomes and decreased complication rates leading to revision or failure.

“…The orientation of the acetabular cup remains a major challenge in total hip arthroplasty (THA) (Lewinnek, et al 1978) . New tools are continuously developed to allow orthopaedic surgeons to measure clinical parameters and assist them in their task (Dardenne, et al 2009) (Rivière, et al 2018). The sterEOS planning software developed by EOS Imaging® allows, from EOS images, the three dimensional measurement of several pelvic parameters useful in total hip arthroplasty (THA): the acetabulum inclination and anteversion, the femoral head diameter, the offset, the femoral neck length, the CCD angle, the femur torsion, the pelvic incidence, the sacral slope, the pelvic version, the pelvic obliquity, the pelvis axial rotation and the anterior pelvic plane (APP) inclination.…”

SterEOS is a software developed by EOS Imaging® allowing the measurement of 3D orthopaedic parameters on two bi-planar radiographs. The goal of this preliminary study was to assess the reliability of the pelvic measurements. Two observers, a novice and an intermediate user, measured three times these parameters on pre and postoperative EOS images coming from ten patients. Intra- and inter-observer precision have been evaluated with intra-class coefficient (ICC) and Bland-Altman graphs. On preoperative EOS images, a high intra- and inter-observer precision (ICC>0.8) was obtained for the measurement of the femoral head diameter, the femur length, the pelvic version and the pelvic obliquity. The offset, the femoral neck length, the pelvic incidence and the sacral slope measurement had a high intra-observer precision but a lower inter-observer precision. The measurement of the acetabulum inclination and anteversion, the CCD angle, the femur torsion, the pelvic rotation and the anterior pelvic plane inclination had a low intra- and inter-observer precision. Similar results were found on postoperative EOS images. Our results are partially consistent with the literature since authors found high intra- and inter-observer precision for all pelvic parameters. Further studies are therefore needed to evaluate the impact of the observer experience on the reliability of those measurements.
