New Study Examines Anatomic Structures and Range of Motion Restrictions in Hip Normal Movement – a Cadaveric Study

Traditional studies of hip kinematics have not identified which anatomic structures limit the range of motion (ROM) when the hip is placed in different maneuvers. In this study, Dr. Incavo and co-authors attempted to answer two questions: (a) During which maneuvers is the motion of the hip limited by bony impingement between the femur and pelvis? (b) When is hip ROM determined by the constraint of soft tissues and to what extent? They measured the ROM of eight cadaveric hips in 17 maneuvers using a motion capture system. The study was published in the Journal of Orthopaedic Research.  Read full abstract.
