Before any operative instrumentation, fluoroscopic images were taken of the native hip joint at 12.5\u2010lb intervals between 0 and 100 lbs of axial traction on a postless traction table. Distraction was calculated as the difference between the total joint space at each traction interval and the baseline joint space. Labral height was measured on magnetic resonance imaging sagittal reformats at approximately 1:30 on the acetabular clockface by a musculoskeletal fellowship\u2010trained radiologist blinded to the traction data.
