Procedure for repairing foot injury

Abstract

A drill guide assembly having an elongated body is configured with a first and second arm members extending from the elongated body. The second arm member is configured and adapted to be longitudinally movable along the elongated body towards and away from the first arm member for reducing fractured bones for repair. A guide housing provided on the second arm member is fitted with a removable sleeve. The removable sleeve is provided with a longitudinal bore for guiding a guide wire or a drill bit for drilling into the bones.

1 - 41 . (canceled) 
     
     
         42 . A depth gage comprising:
 a hollow body having an opening at one end for receiving a member having a length;   a spring-loaded piston provided within said hollow body and arranged so as to urge said member through said opening, wherein when the member is inserted into said opening so as to push the spring-loaded piston away from said opening, the distance traveled by the piston provides an indication of the length of the member located outside the depth gage.   
     
     
         43 . The depth gage of  claim 42 , wherein said member is a K-wire. 
     
     
         44 . The depth gage of  claim 42 , wherein the piston is located within a bore defined by the hollow body so as to be configured to travel in longitudinally the bore. 
     
     
         45 . The depth gage of  claim 44 , wherein an elastically compressible member is located within the bore so as to extend between a closed end of the hollow body and the piston. 
     
     
         46 . The depth gage of  claim 45 , wherein the piston and the compressible member fixed to one another. 
     
     
         47 . The depth gage of  claim 44 , wherein the piston includes a pair of guide pins that project into the openings  66  for guiding the piston as it is slides longitudinally within the bore. 
     
     
         48 . The depth gage of  claim 44 , wherein a guide pin is disposed through the piston. 
     
     
         49 . The depth gage of  claim 45 , wherein the bore is closed off by a pin located within the bore so as to prevent the elastically compressible member from falling out through that end. 
     
     
         50 . A depth gage comprising:
 a cannulated body having first and second ends and a bore longitudinally extending through the length of the body;   wherein said bore is closed at said first end and open at said second end, said open second end sized to receive a member;   a slot defined by the body, said slot extending longitudinally over a portion of the body;   a piston provided within said bore configured to travel in longitudinal direction within said bore;   an elastically compressible member provided within said bore extending between said closed first end of the body and said piston;   a graduated rule provided on the body's outer surface along said slot opening;   an indicator connected to said piston through said slot whereby when a member is inserted into said open second end and urges said piston towards the closed first end of the body compressing said elastically compressible member, said indicator moves along with the piston and indicates a value on the graduated rule,   wherein the elastically compressible member keeps the piston in contact with said member.
