Acetabular dysplasia in the Sami population: a population study among Sami in north Norway.

Objectives: The overall aim of this study was to evaluate the acetabular coverage of the femoral head as measured by the centre-edge (CE) angle of Wiberg and to evaluate any association between low back pain and hip dysplasia in a Sami-dominated area (the municipalities of Karasjok and Kautokeino) in north Norway.

Study Design: A cross-sectional population-based study, which included questionnaires and a radiographic examination of the hips.

Methods: A total of 1723 individuals were invited to participate in a general health survey.
