  • Description: <jats:title>Abstract</jats:title><jats:sec><jats:title>Background</jats:title><jats:p>Low back pain (LBP) has been associated with worse hip function for persons with femoroacetabular impingement syndrome (FAIS). Reports are limited to surgical populations and based on the presence or absence of LBP, regardless of pain severity.</jats:p></jats:sec><jats:sec><jats:title>Objectives</jats:title><jats:p>To report the prevalence of clinically significant LBP for persons with FAIS; compare demographics, pain, and function between those with and without clinically significant LBP; and evaluate relationships between hip function and both LBP‐related disability and LBP severity. We hypothesized that participants with LBP would be older, have higher body mass index (BMI), and report worse groin pain, longer symptom duration, and worse hip function. We hypothesized that worse LBP‐related disability and LBP severity would be related to worse hip function.</jats:p></jats:sec><jats:sec><jats:title>Design</jats:title><jats:p>Observational cross‐sectional study.</jats:p></jats:sec><jats:sec><jats:title>Setting</jats:title><jats:p>Hip preservation clinic.</jats:p></jats:sec><jats:sec><jats:title>Participants</jats:title><jats:p>158 persons with FAIS.</jats:p></jats:sec><jats:sec><jats:title>Interventions</jats:title><jats:p>n/a</jats:p></jats:sec><jats:sec><jats:title>Main Outcome Measure(s)</jats:title><jats:p>Visual analog pain scales (VAS 0‐100) were used to categorize participants with (≥30) and without (&lt;30) clinically significant LBP. Age, sex, BMI, pain severity and duration, and hip function (33‐item Hip Outcome Tool [iHOT33]) were compared between those with and without clinically significant LBP. Correlations were evaluated between the modified Oswestry Disability Index (ODI) and iHOT33, ODI and groin pain severity, LBP severity and iHOT33, and LBP and groin pain severity.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>Sixty percent of participants reported clinically significant LBP (n = 95). These participants reported worse iHOT33 scores (mean difference: 10.1 points) than those without clinically significant LBP (<jats:italic>p</jats:italic> = .001). Worse ODI scores were associated with worse iHOT33 scores (<jats:italic>P</jats:italic> &lt; .001; ρ = −0.74). Significant relationships were also observed between (1) ODI and groin pain, (2) LBP and iHOT33, and (3) LBP and groin pain, but the magnitudes of these correlations were weak (ρ ≤ 0.36).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Clinically significant LBP is highly prevalent in persons with FAIS and is associated with worse hip function. Worse LBP‐related disability, but not LBP severity, was strongly associated with worse hip function.</jats:p></jats:sec>
