Musculoskeletal data suitable for use in biomechanical analyses of hip function are presented. These data were obtained by marking the approximate locations of hip muscle attachment points on the bony pelvis and right femur of an adult, male, dry bone specimen. The coordinates of these points and certain bony landmarks were measured in a convenient laboratory reference frame and transformed to standardized reference frames embedded in the pelvis and femur. A straight line model is used to represent hip muscle force effects, and two applications of the model are cited. The validity of the model was established by examining the interactions between elastic strings joining the muscle attachment points on a connected pelvis and femur, for a variety of hip configurations. Model accuracy is limited both by the approximations associated with all straight line muscle models, and by the method used to include two-joint muscles in the model.
