“…Inter-and intraobserver repeatability was moderate or better for all radiographic measurements, as reported in a prior study of Cohort 1 [15]. The respective kappa values for inter-and intraobserver reads were 0.82 and 0.82 for coxa profunda, 0.59 and 0.68 for the crossover sign, and 0.71 and 0.85 for the posterior wall sign.…”

“…One player had an activities of daily living subscore of 72% and a sports subscore of 78%. This subject had bilateral coxa profunda and crossover signs and the lowest femoral headneck offset of the cohort [15]. Four additional players had a sports subscore of between 80% and 90%, one of which had coxa profunda of the right hip.…”

“…First, our symptomatic patients were represented by two patient cohorts with a predisposition to either acetabular over-or undercoverage rather than a single series of consecutive patients treated for hip pain at our institution. Second, our asymptomatic subjects were not fully representative of the general population but were a rather unique cohort of male collegiate football players previously reported to have a high prevalence of radiographic findings consistent with FAI [15]. Regardless of these possible limitations, these cohorts enabled us to fulfill our main purpose, which was to determine whether coxa profunda is found in both asymptomatic and symptomatic hips representing the spectrum of acetabular coverage.…”

“…Cohort 1 included radiographs of 67 asymptomatic male football players obtained as part of a prospective, institutional review board-approved study to determine the incidence of radiographic findings of FAI in collegiate football players [15]. Each subject completed a short questionnaire on the same day the radiographs were taken.…”

Background Coxa profunda, or a deep acetabular socket, is often used to diagnose pincer femoroacetabular impingement (FAI). Radiographically, coxa profunda is the finding of an acetabular fossa medial to the ilioischial line. However, the relative position of the acetabular fossa to the pelvis may not be indicative of acetabular coverage. Questions/purposes We therefore determined the incidence of coxa profunda and evaluated associations between coxa profunda and other radiographic parameters of acetabular coverage commonly used to diagnose pincer FAI and acetabular dysplasia.Methods We evaluated the radiographs of three cohorts for coxa profunda, lateral center edge (LCE) angle, acetabular index, posterior wall sign, and crossover sign. Data from 67 collegiate football players were collected prospectively (Cohort 1). We identified two patient cohorts Results In all three cohorts, we detected no difference in the LCE angle or acetabular index between hips with and without coxa profunda. Coxa profunda existed in hips representing the spectrum of acetabular coverage measured by LCE angle (À18°to 60°) and acetabular orientation determined by the crossover sign. Conclusions Coxa profunda was a common radiographic finding in both symptomatic patients and asymptomatic football players. Coxa profunda existed in hips representing the spectrum of acetabular coverage and was not associated with an overcovered acetabulum. We conclude coxa profunda is unrelated to overcoverage and suggest its use in diagnosis of pincer FAI be abandoned in favor of other determinants of focal or general overcoverage. Level of Evidence Level III, diagnostic study. See Instructions for Authors for a complete description of levels of evidence.

“…Young adults with more severe morphologic abnormalities and high-level vigorous athletes (football, soccer, hockey) are at higher risk of developing FAI [8]. Surgical treatment mainly with femoral and/or acetabular osteochondroplasty can be achieved with either open or arthroscopic techniques.…”
