Sagittal pelvic kinematics along with spino-pelvic angular parameters have
recently been studied by numerous investigators for their effect on total hip
replacement (THR) clinical outcomes, but many issue of spine-hip relations (SHR)
are currently unexplored. Therefore, our review aims at clarifying the following
questions: is there any evidence of a relationship between articular
impingement/dislocation risk in primary THR and (1) certain sagittal pelvic
kinematics patterns, (2) pelvic incidence, and (3) types of SHRs? A systematic
review of the existing literature utilising PubMed and Google search engines was
performed in January 2017. Only clinical or computational studies published in
peer-reviewed journals over the last five years in either English or French were
reviewed. We identified 769 reports, of which 12 met our eligibility criteria. A
review of literature shows that sagittal pelvic kinematics, but not the pelvic
incidence, influences the risk of prosthetic impingement/dislocation. We found no
study having assessed the relationship between this risk and the types of SHRs.
Sagittal pelvic kinematics is highly variable among individuals and certain
kinematic patterns substantially influences the risk of prosthetic
impingement/dislocation. Recommendations for cup positioning are therefore
switching from a systematic to a patient-specific approach, with the standing cup
orientation Lewinneck safe zone progressively giving way to a new parameter of
interest: the functional orientation of the cup. Based on a recently published
classification for SHRs, We propose a new concept of "kinematically aligned THR"
for the purposes of THR planning. Further studies are needed to investigate the
relevance of such a classification towards the assumptions and hypothesis we have
made. Level of evidence,- Level IV, systematic review of level III and IV studies.
