Radiologic Findings and Clinical Significance of the Herniation Pits of the Femoral Neck / 实用放射学杂志

ABSTRACT

Objective To study the incidence and clinical significance of the herniation pits of the femoral neck.Methods 600 cases(299 men,301 women,18～82 years)were collected.The incidence,radiologic finding and clinical significance of the herniation pit of the femoral neck were analysed.Results Of 1200 hip joints in 600 cases,there was 58 cases(64 sides)(5.3%)with herniation pits of the femoral neck,including 39 men(68.7%)and 19 women(31.3%),the lesions localized in the left joint in 25 eases(39.1%),in the right joint in 27 cases(42.2%)and in bilateral joints in 6 cases(18.7%).There were a obvious significant differences on both sexes,and no significant differences on age groups.On X-ray film,the lesions appeared as a round radiolucency with thin clear sclerotic rim.Conclusion The incidence of the herniation pit of the femoral neck is 5.3%,which has a typical X-ray feature,and may indicate the femoroacetabular impingement.
