Prevalence of Radiographic Parameters Predisposing to Femoroacetabular Impingement in Young Asymptomatic Chinese and White Subjects

Abstract

Background: Osteoarthritis of the hip is five to ten times more common in white people than in Chinese people. Little is

Prevalence of cam hip shape morphology: a systematic review

“…Table I provides a description of the 30 included studies. Eight studies originated from the USA 19e21,42e46 , five were from Japan 15,47e50 , two from the Netherlands 5,51 , Belgium 52,53 , Brazil 54,55 , South Korea 56,57 and Germany 58,59 . There were single studies from Denmark 10 , Canada 16 , New Zealand 60 , Turkey 61 , UK 62 , Switzerland 63 and Italy 64 .…”

Computer-based estimation of the hip joint reaction force and hip flexion angle in three different sitting configurations

“…The resulting intra-articular damage is responsible for hip pain of which FAI patients often complain during prolonged sitting, especially in low car seats (Larson and Giveans, 2008;Parvizi et al, 2007;Philippon et al, 2007a). With a reported radiographic prevalence of FAI at-risk signs of 30e70% in the Caucasian population (Frank et al, 2015;Jung et al, 2011;Kapron et al, 2011;Van Houcke et al, 2015) and a likely association with hip osteoarthritis development (Ganz et al, 2003(Ganz et al, , 2008Reid et al, 2010), FAI represents a relevant disease burden (Agricola and Weinans, 2016).…”

The History of Biomechanics in Total Hip Arthroplasty

“…The average value is 44 mm and increases with both the femoral size and decreasing neck-shaft angle [Figure 4]. 1922 The average neck-shaft angle in Caucasians is approximately 130°, with males tending more toward varus 2324. Besides the impact of the neck-shaft angle in the coronal plane, the amount of femoral version in the axial plane also influences the femoral offset 1925.…”
