ABSTRACT Objective: To assess the adequacy to the Brazilian population of orthopedic implants used for treatment of proximal femoral fractures. Methods: The neck-shaft angle of the femur of 101 patients was measured in anteroposterior pelvis radiographs and these measurements were correlated to gender, age, height, weight and ethnicity. In addition, we compared the values of the neck -shaft angle with the angulation of the main implants available in the Brazilian market for the treatment of transtrochanteric fractures. Results: Of the 101 measurements, an average of 130.9±6.7° was obtained, ranging from 112° to 150°. Correlating these measurements with epidemiological variables, only age was statistically significant. Conclusion: Most of the analyzed population presented anatomical characteristics that allow the proper use of these implants to treat transtrochanteric fractures, as indicated from the analysis of neck-shaft angles. Nonetheless, 4% of individuals did not fit this pattern and would have required alternative implants. Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference ''gold'' standard.

RESUMO A dor glútea é um sintoma frequente em atletas. Sua definição etiológica é um desafio para o ortopedista. No presente estudo, os autores propõem, por meio de uma abordagem anatômica da região posterior da pelve e do fêmur proximal, dividida em quatro quadrantes, a investigação sistematizada do local, visando, por meio do diagnóstico correto, a aperfeiçoar o tratamento e acelerar o retorno do atleta ao esporte.

ABSTRACT Gluteal pain is a frequent symptom in athletes, and defining it etiologically is a challenge for orthopedists. In the present study, using an anatomical approach to the posterior region of the pelvis and the proximal femur, divided into four quadrants, systematized investigation is proposed with the aim of optimizing the treatment and accelerating athletes' return to their sport, through correct diagnosis.
