The role of herniation pits as a radiographic indicator is still debated This case–control study was to determine 1 the prevalence and sizes of herniation pits and 2 the relationship between herniation pits and femoral and acetabular bony morphology consistent with femoroacetabular impingementThis comparative study was performed on 151 patients 151 hips median patient age 46 years range 16–73 years with mechanical symptoms who underwent multidetector computed tomography MDCT arthrography the symptomatic group and an age gender site left or right and time at diagnosismatched group of control patients that underwent multidetector computed tomography due to an ureter stone the asymptomatic group Two orthopaedic surgeons reviewed images to evaluate the prevalence sizes of herniation pits and relationship with morphological abnormalityThe prevalences of herniation pits in symptomatic and asymptomatic groups were 238 36/151 and 33 5/151 respectively OR 914 95 CI 347–2430 p 0001 Herniation pits were found to be significantly associated with pincertype abnormality p = 0034 especially central acetabular retroversion p 0001This study shows that the prevalence of herniation pits is higher in symptomatic patients with femoroacetabular impingement and herniation pits are associated with central acetabular retroversion Furthermore herniation pits were also found to be a useful predictor of pincertype femoroacetabular impingementThe authors did not receive any outside funding or grants in support of their research for or preparation of this work Neither they nor a member of their immediate families received payments or other benefits or a commitment or agreement to provide such benefits from a commercial entity No commercial entity paid or directed or agreed to pay or direct any benefits to any research fund foundation division centre clinical practice or other charitable or nonprofit organization with which the authors or a member of their immediate families are affiliated or associated
