In adolescents without hip pathology, results published in the Journal of Children’s Orthopaedics showed epiphyseal tilt had no age-specific variations, as well as showed no difference in male and female patients in the superior and anterior plane.
Using pelvic CT scans, researchers reformatted radially oriented planes around the femoral neck and measured the epiphyseal tilt and angle in the anterior, anterosuperior and superior planes of 132 adolescents who presented with abdominal pain. Researchers used linear mixed model analysis to assess variations in the tilt angle and epiphyseal angle by age group from 12 to 18 years and by gender.
Results showed no change in epiphyseal tilt with increasing age. Although male patients had a smaller tilt angle in the anterosuperior plane, researchers found no difference in the anterior or superior planes. Male patients experienced a decrease in the epiphyseal angle in the anterior, anterosuperior and superior planes with increasing age. However, researchers noted no variation in epiphyseal angle with increasing age in female patients. Compared with female patients, researchers found larger epiphyseal angles in the anterior, anterosuperior and superior planes in male patients. – by Casey Tingle
