| Abstract | ||
| Background: Femoral neck anteversion (FNA) is a physiological torsion of the femur that plays an important role in the stability & function of the hip joint and has a great impact on the rotational movements of the hip. Abnormal development of the FNA may be associated with a number of orthopaedic problems affecting the hip joint & gait ranging from in-toing gait to disabling osteoarthritis. The assessment of the angle is therefore important in assessing such problems & determining the best course of action in their management. Aims: this study aims at measuring the FNA angle in healthy Iraqi children & examining its impact on hip rotational movements at different age groups. Patients and methods: 36 healthy Iraqi male children divided into 3 age groups were examined clinically for the range of hip rotation & were then subjected to X-ray estimation of the FNA angle of their hips using Ogata’s Biplanar method. Results & conclusions: all the children had FNA angles & hip rotational movements within the normal range for their age with a significant regression in FNA angle with increasing age that may be related to muscular torsional forces applied to growing epiphyses. The FNA angle was inversely proportional to lateral rotation of the hip but directly proportional to medial rotation. Sides to side differences were noticed in tested subjects and were statistically significant in the (8-9 years) age group. This bilateral disparity may normally result from cerebral lateralization or prolonged postural dynamic factors affecting the joints & soft tissues. | ||
