Relationship between hip pathoanatomy and symptomatic FAI has been reported to be
weak. This is explained by the reciprocal interaction between proximal femur and
acetabular anatomies, but potentially also by the individual spine-hip relations
(SHR). The key-answer for a complete understanding of the pathophysiology of FAI
might lie in the comprehension of the SHRs, which have not yet been fully addressed. Therefore we conducted a systematic review to answer the subsequent
questions: Is there any evidence of a relationship between FAI and (1) sagittal
pelvic kinematics, (2) pelvic incidence, and (3) types of SHRs? A systematic
review of the existing literature utilizing PubMed and Google search engines was
performed in December 2016. Only studies published in peer-reviewed journals over
the last ten years in either English or French were reviewed. We identified 90
reports, of which 9 met our eligibility criteria. Review of literature shows
Caucasian FAI patients have a pelvis with higher anterior tilt, lesser sagittal
mobility, and lower pelvic incidence compared to healthy patients. We found no
study having assessed the relationship between SHR and FAI. In order to help
further investigations at answering questions 3 and 4, we have developed a
classification for SHRs.
The classification according spino-pelvic parameters
allows identifying patient at risk regarding FAI occurrence. Higher anterior
pelvic tilt in standing, sitting and squatting positions and lower pelvic
incidence have been found to correlate with symptomatic FAI. Because defining the
individual SHR might increase the understanding of the pathophysiology of hip
impingement, we have developed a classification for SHRs. LEVEL OF EVIDENCE:
Level IV, systematic review of Level III and IV studies.
