title: FEMORAL ANTEVERSION AND THE NECK-SHAFT ANGLE: RELATIONSHIP WITH HIP OSTEOARTHRITIS.
abstract: OBJECTIVE
  To compare the existence of agreement between measurements of anteversion of the femoral neck and the degrees of osteoarthritis and abnormality of the neck-shaft angle in patients with unilateral idiopathic hip osteoarthritis, among three evaluators.
  
  
  METHODS
  Forty-two patients with unilateral hip osteoarthritis were evaluated by means of simple radiography and computed tomography.
  
  
  RESULTS
  It was observed that there was no significant variation in femoral anteversion between the diseased and healthy hips. There was strongest agreement between observers 1 and 2 in relation to both the diseased hips (cases) and the healthy hips (controls). Moreover, no significant agreement was found between observers 1 and 3 (p = 0.13) and between observers 2 and 3 (p = 0.12), in relation to the neck-shaft angle of the control hips.
  
  
  CONCLUSIONS
  Although there was no relationship between femoral anteversion and the neck-shaft angle in the patients with unilateral hip osteoarthritis, the present study showed that there was also no relationship with these angular deviations.
