PROBLEM: This paper investigates which angles of acetabular (AA) and @entity2096 ( @entity2096 ) have to be considered as normal and which ones cause changes in range of movements, @entity158 and @entity571 . METHOD OF INVESTIGATION: 15-20 degrees of anteversion of AA and @entity2096 were tested regarding normality. Diminished anteversion angles were divided in groups -2 and -3, and increased angles in groups +2 and +3. RESULTS: The material consisted of 356 hip joints with computerized tomographies, investigated separately in @entity85 . Changes in range of movement, @entity158 and @entity571 were minimal in the normal angle group 1 and increasing in the extreme angle groups -2 and -3 and +2 and +3. Diminished AA and @entity2096 cause a decrease of internal rotation of the hip and an increase of external rotation, @entity158 and @entity571 . When groups of diminished AA or @entity2096 angles were found combined with the normal angle group 1 or increased angles of AA or @entity2096 (+2/+3), the pathological consequences were compensated or diminished especially by higher @entity2096 angles and less by AA angles. The results in all investigations were statistically significant if the number of observations was large enough. The instability index of McKibbin was used in the different angle groups of deviation from normal. Adding the angles of AA and @entity2096 together gives a good impression of the degree of @entity2003 and the prognosis of the joint. SIGNIFICANCE: In @entity1 and adults diminished AA and @entity2096 are quite frequent. They cause @entity158 and @entity571 , but are diagnosed seldom.
