Abstract
in English, Portuguese

Objective: To evaluate the correlation between radiographic parameters of the proximal femur with femoral neck fractures or transtrochanteric fractures.

Methods: Cervicodiaphyseal angle (CDA), femoral neck width (FNW), hip axis length (HAL), and acetabular tear drop distance (ATD) were analyzed in 30 pelvis anteroposterior view X-rays of patients with femoral neck fractures (n = 15) and transtrochanteric fractures (n = 15). The analysis was performed by comparing the results of the X-rays with femoral neck fractures and with transtrochanteric fractures.

Results: No statistically significant differences between samples were observed.

Conclusion: There was no correlation between radiographic parameters evaluated and specific occurrence of femoral neck fractures or transtrochanteric fractures.

Objetivo: Correlacionar parâmetros radiográficos do fêmur proximal com a ocorrência de fraturas do colo do fêmur ou fraturas transtrocantéricas do fêmur.

Métodos: Foram avaliados o ângulo cevicodiafisário (ACD), a largura do colo femoral (LCF), o comprimento do eixo do quadril (CEQ) e a distância entre as lágrimas acetabulares (DL) de radiografias de bacia em incidência anteroposterior de 30 pacientes com fratura de colo de fêmur (n = 15) e fratura transtrocantérica de fêmur (n = 15). A avaliação foi feita com a comparação dos pacientes com fratura de colo de fêmur com os pacientes com fratura transtrocantérica.

Resultados: Não foram observadas diferenças estatisticamente significantes entre as amostras obtidas entre os dois grupos comparados.

Conclusão: Não houve correlação entre os parâmetros radiográficos avaliados e ocorrência específica de fraturas de colo de fêmur ou fraturas transtrocantéricas de fêmur.
