  • Methods for distracting, imaging, and evaluating hip joint laxity
    Patent number: 6154670
    Abstract: A method for distracting a coxofemoral joint of a patient having two hind legs includes the steps of placing the patient in ventral recumbency, positioning a distractor between the upper thighs so that the distractor acts as a fulcrum for lateral displacement of the coxofemoral joint, and applying inward pressure to the stifle regions to distract the coxofemoral joint. Related methods are also disclosed for imaging a distracted coxofemoral joint and for evaluating the likelihood of developing laxity of a coxofemoral joint in a patient. The imaging can be non-radiographic. A distractor apparatus, suitable for use in the methods, is also described.
