Validity of visual examination for femoral neck anteversion between (1-10 years old)


Background: Femoral Anteversion is a condition in which the femoral neck leans forward with respect to the rest of the femur. This causes the lower extremity on the affected side to rotate internally. Because some degrees of rotation of the femur is always presented during children’s growth, it is considered abnormal only if it is significantly different from the average value of a patient of the same age.Aim: To investigate the validity of visual angles estimation of hip joint.Study design: case series study in the Al-Jumhorei teaching hospital. Total 121 patients have been examined (51 males and 70 females), ages varies between 1year -10 years.Study period: 1st June 2010-1st Dec 2010 Methodology: Visual femoral neck examination has been carried for determination of hip joint motion in the internal position carried by the first examiner, and the second proved the femoral neck position by application of Goniometer, comparison of both reading has been recorded and analysis carried on.Results: Specificity of visual determinations for femoral neck anteversion of females appeared to be 90% for the right hips, males left hips appeared to be 100% ,while in studying both groups appeared to be 95% ,92% for each right and left hips respectively, with highly significant P ≤ 0.000. Conclusion: Visual determination of femoral neck anteversion proved to be an easy, quick, safe, valid and accurate method for screening hip joint alignment. Key word: Femoral neck anteversion, visual examination, reliability and validity
