Abstract: An intramedullary nail for use in a medullary canal of a long bone. The nail includes a body defining a longitudinal axis and an external periphery for fitting in the medullary canal of the long bone. The body has a first internal wall thereof defining a first opening through the body, defining a first opening centerline. The body has a second internal wall defining a second opening through the body, defining a second opening centerline. The first opening centerline and the second opening centerline are oblique with respect to each other. The longitudinal axis of the body and the first opening centerline form an acute angle between the longitudinal axis of the body and the first opening centerline. The longitudinal axis of the body and the second opening centerline forming an acute angle between the longitudinal axis of the body and the second opening centerline.

Abstract: An intramedullary nail for use in a medullary canal of a long bone is provided. The nail includes a body defining a longitudinal axis of the body and an external periphery of the body for fitting in the medullary canal of the long bone. The body has a first internal wall thereof defining a first opening through the body. The first opening defines a first opening centerline. The body has a second internal wall of the body defining a second opening through the body. The second opening defines a second opening centerline. The first opening centerline and the second opening centerline are oblique with respect to each other. The longitudinal axis of the body and the first opening centerline form an acute angle between the longitudinal axis of the body and the first opening centerline. The longitudinal axis of the body and the second opening centerline forming an acute angle between the longitudinal axis of the body and the second opening centerline.

Abstract: Locking screw system includes screw and female threaded receiver that provide for and lock through interference fitting, which may be from major-major and/or minor-minor diameter interference. The system may be embodied as an orthopedic implant or implant component.

Abstract: A depth gage for use with a drill in orthopaedics is provided. The depth gage includes a body. The body has first and second ends opposed to each other and an inner periphery defining a longitudinal aperture through the body for slidably receiving the drill. The longitudinal aperture defines a longitudinal axis of the longitudinal aperture. The body is adapted to permit the drill to be positioned in the longitudinal aperture in a direction non-coincident with the longitudinal axis.

The nail includes a body defining a longitudinal axis of the body and an external periphery of the body for fitting in the medullary canal of the long bone. The body has a first internal wall thereof defining a first opening through the body. The first opening defines a first opening centerline. The body has a second internal wall of the body defining a second opening through the body. The second opening defines a second opening centerline. The first opening centerline and the second opening centerline are oblique with respect to each other. The longitudinal axis of the body and the first opening centerline form an acute angle between the longitudinal axis of the body and the first opening centerline. The longitudinal axis of the body and the second opening centerline forming an acute angle between the longitudinal axis of the body and the second opening centerline.

Abstract: Screw system is useful for transiliac fixation of a sacrum and/or sacroiliac joint and/or for application in other skeletal areas, and includes a cannulated bone screw preferably capable of spanning iliac crests of a patient, having an elongate, hollow body with openings on a first end of the body and on an opposing, second end of the body; a tip on the first end of the body, which preferably is a thread-cutting tip that can engage and thread the ilia or other bone of the patient; a head about the second end of the body, which can be engaged with a surgical tool; and threads on at least part of the body between the first and second ends; a locknut with threads for interference fitting corresponding generally to those of the screw for threading on the screw; and preferably also a washer. Major-minor, pitch-diameter, locking interference fitting can be provided.
