From: Pelvic posture and kinematics in femoroacetabular impingement: a systematic review
Field of investigation | Subfield of investigation | Study | Methods | Main findings | Main limitations |
---|---|---|---|---|---|
Pelvic posture | Pelvic incidence | Gebhart et al. [24] | Photography and manual goniometry | PI is lower in cam- and pincer-FAI than in normal hips | Only male cadaveric specimens; poor diagnostic criteria for pincer-FAI |
Hellman et al. [25] | Radiology | Symptomatic pincer and combined FAI have lower PI than healthy hips and pure cam-FAI | Historical healthy controls | ||
Weinberg et al. [22] | Radiology | Mixed-FAI have lower PI than controls | Retrospective CT review, without most clinical information | ||
Pelvic posture in acetabular dysplasia with cam deformity | Ida et al. [28] | Radiology | The presence of cam deformity increases the forward PT among dysplastic hips (only in upright position) | PI not measured | |
Pelvic kinematics | Hip flexion without weight-bearing | Van Houcke et al. [29] | Motion capture analysis | Higher pelvic back tilt with supine hip flexion in cam-FAI patients compared to healthy controls (only with active motion) | Blinding and intra-/inter-rater reliability not mentioned |
Walking and stair climbing | Kennedy et al. [30] | Motion capture analysis | Cam-FAI patients show less frontal pelvic ROM than healthy controls in level walking. No difference of axial and sagittal ROM | Blinding and power analysis not mentioned. No ROM exact values reported | |
Rylander et al. [31] | Motion capture analysis | Pincer- and mixed-FAI patients display higher pelvic forward tilt and axial ROM while climbing stairs than healthy controls, both before and after surgery. No difference in level walking | No physical or radiological examination of healthy controls. Blinding and intra-/inter-rater reliability not mentioned | ||
Squat | Lamontagne et al. [32] | Motion capture analysis | Cam-FAI patients squat higher than control, with lower sagittal pelvic ROM and more pelvic forward tilt at maximum depth | Blinding and intra-/inter-rater reliability not mentioned | |
Lamontagne et al. [33] | Motion capture analysis | Cam-FAI patients squat lower after corrective surgery, but sagittal pelvic ROM is not improved | Blinding and intra-/inter-rater reliability not mentioned. No ROM exact values reported | ||
Ng et al. [34] | Motion capture analysis | Low sagittal pelvic ROM is a crucial feature (along with α angle and neck-shaft angle) to determine symptoms in cam-FAI patients | – | ||
Wilson et al. [21] | Motion capture analysis | FAI patients squat lower if knee separation is allowed | Exact FAI type not reported. Blinding and intra-/inter-rater reliability not mentioned | ||
Bagwell et al. [23] | Motion capture analysis and force plate | Cam-FAI patients squat higher than controls but with less posterior PT, likely because the extensor moment is reduced. Reduced hip internal rotation | No blinding mentioned |
