With coverage during standing (r = 0.929 – 0.989). Coverage at each time point of gait strongly correlated Results: For total coverage, very little change in coverage occurred during gait (range:ģ5.0 – 36.7% mean: 36.2%). Coverage in standing was correlated with that (anterior, superior, posterior, inferior). Standing position and during gait was measured overall and on a regional basis Measured in-vivo for eleven asymptomatic morphologically normal subjects using dualįluoroscopy and model-based tracking of 3-D CT models. Materials and Methods: The kinematic position of the hip during standing and gait was Relationship between 3-D femoral head coverage in standing to that measured during The objectives of this study were to: 1) quantify total and regional 3-Dįemoral head coverage in a standing position and during gait, and 2) quantify the Static assessments of coverage may not provide accurate information regarding theĭynamic, three-dimensional (3-D) relationship between the femoral head andĪcetabulum. Femoral head coverage is typically evaluated using radiographs, and/orĬomputed tomography (CT) or magnetic resonance images obtained supine. Introduction: Individuals with over- or under-covered hips may deve lop hip May lead to differences between this version and the Version of Record.
