Patent ID: 7905924

Claim:
A method of providing a stabilizing extracapsular surgical repair for an articulating joint between two bones in a mammalian subject, comprising: (a) obtaining a pair of images, a first image of said pair showing said articulating joint in a fully flexed position and a second image of said pair showing said articulating joint in a fully extended position; (b) in said images identifying a pair of points between which to provide an extracapsular tension-carrying structure interconnecting said two bones, said pair of points being a reference point on a first one of said two bones and an isometric point on the second one of said two bones, said reference and isometric points being located in said joint so as to be separated by a separation distance that is equal in both of said first and second images; (c) providing a measuring and locating device having: (i) a body; (ii) a pair of locating portions associated with a said body, at least one of said locating portions being adjustably located with respect to said body; and (iii) a scale capable of providing an indication of a separation distance between said locating portions; (d) locating said reference point in said first one of said bones in said articulating joint in said subject; (e) thereafter, locating a trial isometric point on said second one of said bones in said articulating joint in said subject by fastening a first marking element at said reference point and holding a second marking element in said second locating portion of said device at said separation distance with said articulating joint in a first one of a fully extended position and a fully flexed position; (f) moving said articulating joint to the other one of said fully extended and fully flexed positions and observing whether said reference point and said trial isometric point are then separated by said separation distance; and adjusting the position of said second locating member with respect to said trial isometric point until an isometric point is located on said second one of said bones of said articulating joint; and (g) surgically attaching a tension-bearing repair structure to said bones as necessary to provide tension-bearing structure extending between respectively said reference point and said isometric point as thus located in said joint.
