Claim:
1. A medical instrument comprising: a base; a twisting head rotatably coupled to the base to twist portions of at least one bone-securing flexible suture together in response to relative rotation of the twisting head with respect to the base; a flexible suture retaining structure in which the at least one bone-securing flexible suture is retained, at least a portion of the flexible suture retaining structure movably coupled to the twisting head; and a torsion spring physically coupled to the flexible suture retaining structure to wind up the at least one bone-securing flexible suture in response to the relative rotation of the twisting head with respect to the base, wherein the twisting head is rotatably coupled to the base to decrease a distance between the flexible suture retaining structure and a location on the base in response to the relative rotation of the twisting head with respect to the base.
