Abstract
System, including methods and apparatus, for treating orthopedic conditions using a rod member structured for placement in a medullary canal of a bone and including at least one locking aperture with an internal thread structure. In some embodiments, the internal thread structure may include two or more thread leads disposed adjacent the same end of the locking aperture, two or more interspersed internal threads, and/or a thread depth substantially less than that of a corresponding threaded fastener for the locking aperture.

19. A method of bone fixation, comprising:
-
selecting a rod member defining one or more apertures, at least one of the apertures being a locking aperture including opposing ends and internal thread structure defining two or more thread leads disposed adjacent the same opposing end;
placing the rod member into a medullary canal of a bone; and
connecting the rod member to the bone, at least partially, by advancing a fastener from the bone into the locking aperture such that an external thread of a fastener threads into the internal thread structure via only one of the two or more thread leads. - View Dependent Claims (20, 21, 22, 23)
