“…We also found male hips showed greater mean values for acetabular depth and width 18 , but further that African Americans had overall higher mean values in males and females for these measures than American Caucasians, though non-significant. Our finding of greater femoral head asphericity in African American and American Caucasian males, also corroborates previous studies that found increased prevalence of cam morphology in males for these groups 24 .…”

“…These include measures of acetabular orientation (depth, width, depth to width ratio) 33 , acetabular coverage (LCE) 11,23,32,33 , minimum joint space width as calculated using Bezier curves 30,34,35 , femoral head asphericity (AP alpha angle) 11,33 , femoral morphology (neck length, minimum neck width, head diameter) 36 , femoral alignment (femoral neck shaft angle [FNSA]) 37 . Pelvic width (inter-acetabular edge distance) along with the FNSA and acetabular depth to width ratio were measured due to likely sex-differences 19,24 . Hip morphology measures are described in Figs.…”

“…Among African Americans 20 , Chinese 8 and Japanese 21 , males show greater prevalence of radiographic hip OA (RHOA) than females, with Caucasian groups showing mixed results 20,22 . Pincer-type morphologies are more common in women, with cam-type morphologies more prevalent in males 12,23,24 . These differences may lead to increased risk of OA through changes in joint biomechanics and loading 10 .…”

s u m m a r yObjective: This paper aims to (i) identify differences in measures of hip morphology between four racial groups using anteroposterior (AP) hip x-rays, and (ii) examine whether these differences vary by sex. Methods: 912 hip x-rays (456 individuals) from four racial groups (European Caucasians, American Caucasians, African Americans and Chinese) were obtained. Males and females (45e75 years) with no radiographic hip OA (Kellgren and Lawrence < Grade 2 or Croft < Grade 1) were included. Eleven features of hip joint morphology were analysed. Linear regression with generalised estimating equations (GEE) was used to determine race and sex differences in hip morphology. Post-hoc Bonferroni procedure was used to adjust for multiple comparisons. Results: The final analysis included 875 hips. Chinese hips showed significant differences for the majority of measures to other racial groups. Chinese were characterised by more shallow and narrow acetabular sockets, reduced femoral head coverage, smaller femoral head diameter, and a lesser angle of alignment between the femoral neck and shaft. Variation was found between other racial groups, but with few statistically significant differences. The average of lateral centre edge angle, minimum neck width and neck length differed between race and sex (p-value for interaction < 0.05). Conclusions: Significant differences were found in measures of morphology between Chinese hips compared to African Americans or Caucasian groups; these may explain variation in hip OA prevalence rates between these groups and the lower rate of hip OA in Chinese. Sex differences were also identified, which may further explain male-female prevalence differences for OA.

“…Thus, the isolated presence of either cam or pincer morphology is insufficient for a diagnosis of FAI syndrome. It is important to note that these morphologies are thought to be fairly common (around 30% of the general population) including in people without hip symptoms [9,10].…”

Femoroacetabular impingement (FAI) is an often unrecognized hip disorder in young adults that can lead to early hip osteoarthritis and a decrease in sports performance. The diagnosis and treatment of this entity have rapidly evolved in recent years. Hip arthroscopy finds its place in the treatment of this conflict, and its indications are more and more frequent. The technical challenge of this operation involves a relatively long learning curve and a good knowledge of the hip anatomy in order to minimize the risk of complications and iatrogenic lesions. In addition to intra-articular structures of the hip joint, the anatomical structures that may be affected by the main and accessory arthroscopic approach are primarily the lateral femorocutaneous nerve, the lateral circumflex femoral artery, the medial circumflex femoral artery, and the circumflex superior iliac artery. A little further, 3-5 cm from the main portals, we must pay attention to the femoral nerve, the sciatic nerve, the superior gluteal nerve, the profunda femoris artery, the superficial femoral artery, and the common femoral artery. The pathogenesis of femoroacetabular impingement is not fully understood. The multifactorial origin is still relevant today. We have divided factors incriminated in the genesis of FAI into three groups.
