RESUMO
Objective The present study aimed to determine the average hip anthropometry of a regional Brazilian population using measurements based on computerized axial tomography (CAT). Methods Retrospective, descriptive analysis of hip measurements from 200 abdominal CATs from patients visiting a medical center. The tests were selected at random to determine 30 previously defined anthropometric measurements. The data were statistically analyzed and compared according to gender and age. Results The prevalence of hip dysplasia was 6%. Signs suggesting femoroacetabular impingement were seen in 26% of cases. Patients over 50 years old presented significantly greater measures of horizontal acetabulum sectors, center-edge angle, and acetabular arch, as well as lower extrusion index, cervical-diaphyseal angle and vertical offset. Some measurements were significantly different according to gender: the lateral center-edge angle (µ = 35.5°) and the acetabular arch (µ = 68.7°) were higher in females. Males presented increased extrusion index (µ = 16%), lateral offset (µ = 38.3 mm), depth (µ = 19.5 mm), and neck diameter (µ = 26.4 mm). Conclusion The present study characterized the hip anthropometry of a regional Brazilian population. It also demonstrated significant morphological differences per age group and gender.

Some measurements were significantly different according to gender: the lateral center-edge angle (µ » 35.5°) and the acetabular arch (µ » 68.7°) were higher in females. Males presented increased extrusion index (µ » 16%), lateral offset (µ » 38.3 mm), depth (µ » 19.5 mm), and neck diameter (µ » 26.4 mm).

Resumo Objetivo Determinar a antropometria média do quadril de uma população regional brasileira através de medidas obtidas pela tomografia axial computadorizada (TAC). Método Análise analítico-descritiva, retrospectiva, de medidas coxofemorais de 200 TACs do abdômen de pacientes atendidos em um centro médico. Foram selecionados aleatoriamente exames que permitissem a aferição de 30 medidas antropométricas previamente definidas. Os dados foram estatisticamente analisados e comparados quanto a sexo e idade. Resultados A prevalência de displasia do quadril foi de 6%. Sinais sugestivos de impacto fêmoro-acetabular foramvistosem26% doscasos.A análise dos resultadosnogrupoacima de 50 anos demonstrou medidas significativamente maiores dos: setores horizontais do acetábulo,doângulocentro-bordaedoarcoacetabular,acompanhadosdemenoríndicede extrusão, ângulo cérvico-diafisário e offset vertical. Algumas medidas foram significativamente diferentes em função do sexo: o ângulo centro-borda lateral (µ» 35.5°) e o arco acetabular(µ» 68.7°)semostraram maioresnosexo feminino.Nogrupomasculino,foram maiores o índice de extrusão (µ» 16%), o offset lateral (µ» 38,3mm), a profundidade (µ» 19,5mm) e o diâmetro do colo (µ» 26,4mm). Conclusão O presente estudo caracterizou a antropometria do quadril de uma população brasileira. Demonstrou ainda diferenças morfológicas significativas do quadril entre diferentes faixas etárias e sexos.
