Abstract: A support arm for supporting a surgical device in an operating room. The support arm is comprised of an elongated, tubular extrusion having an inverted, generally tear-drop shaped outer surface that has an airfoil shape. The airfoil shape is symmetrical about an axis extending from a leading end of the airfoil to a trailing end of the airfoil shape.

Abstract: A femur support assembly attachable to a surgical table. The support assembly is comprised of a support plate, and an elongated rod reciprocally movable in a generally vertical direction relative to the support plate. An elongated support is mounted to the rod. The elongated support is rotatable about the rod and has a plurality of like apertures formed thereon. Each of the apertures defines a mounting position. A femur hook is provided having an end dimensioned to be received in one of the plurality of apertures.

Abstract: A sacral support for a surgical table, comprising a plate having two spaced-apart openings formed therein. The openings are aligned along an axis of the plate and disposed adjacent one end of the plate. A pad is attached to the plate. The pad is dimensioned such that the openings in the plate are exposed. A positioning post is attachable to the plate. The post has a lower end dimensioned to be received in the openings in plate, wherein the post is mountable in the plate in one of two different positions.

Abstract: A fastener assembly includes a threaded bolt and a locking nut assembly. The threaded bolt includes at least one longitudinal groove. The locking nut assembly includes a nut adapted to threadingly engage the bolt, a locking ring adapted to engage the bolt and the nut, and a biasing member adapted to bias the locking ring. The nut includes a threaded bore dimensioned to receive the bolt and a plurality of teeth formed on a face of the nut. The locking ring includes at least one inwardly protruding tab dimensioned to be received by the at least one longitudinal groove of the threaded bolt and a plurality of teeth formed on a face of the ring. The teeth on the face of the locking ring cooperate with the teeth on the face of the nut to inhibit removal of the nut from the bolt after the nut has been tightened. A method for manufacturing the fastener assembly and a tool for use with the fastener assembly is also provided.

The locking nut assembly includes a nut adapted to threadingly engage the bolt, a locking ring adapted to engage the bolt and the nut, and a biasing member adapted to bias the locking ring. The nut includes a threaded bore dimensioned to receive the bolt and can include a plurality of teeth formed on a face of the nut. Alternatively, an insert ring can be received by the nut and the insert ring can include teeth. The locking ring includes at least one inwardly protruding tab dimensioned to be received by the at least one longitudinal groove of the threaded bolt and a plurality of teeth formed on a face of the ring. The teeth on the face of the locking ring cooperate with the teeth on the face of the nut, or insert ring, to inhibit removal of the nut from the bolt after the nut has been tightened.
