    摘要: A fracture alignment and retention device includes a plurality of spanning bars which are spaced about the extremity of the patient having a fractured long bone. Preferably, the spanning bars are located circumferentially about the extremity. At least three spanning bars are held in approximately 90 degree offset positions with respect to each other by two straps encircling the extremity. The straps are secured in place by a VELCRO-type fastener or other securing devices. Each spanning bar includes at least two pressure pads which are placed on the extremity on opposite sides of the fracture. Each pressure pad includes a threaded shaft which is threadably mounted at a central portion in a fixed bushing engaged in a slot defined in an uppermost surface of the spanning bar. One end of the shaft includes a knob and the opposite end is mounted on the pressure pad for causing movement of the pressure pad toward or away from the extremity in an axial direction along the shaft without rotation of the pressure pad. Rotation of knobs located at the end of the shaft controls the amount of pressure exerted against the extremity by the pressure pads and includes an indicator for noting relative positioning of a knob prior to and after turning of the knob.

    摘要: An intramedullary rod system includes a guide rod and a tubular hollow intramedullary rod having an interior surface shaped, at least in a portion, complementary to that of the guide rod. The guide rod is first inserted through the medullary canal and then removed after sliding the tubular intramedullary rod over the guide rod. The guide rod is then aligned outside of the leg parallel to the hollow intramedullary rod for engagement at a distal end by bifurcated prongs with a drill bolt with which bifurcated prongs of the hollow intramedullary rod is simultaneously engaged. Screw holes are thereby aligned between the guide rod and the intramedullary rod at the distal end of the bone without the use of targeting. The hollow intramedullary rod is aligned with the guide rod by a lateral guide for accurate insertion through the guide rod of screws at the distal end of the hollow intramedullary rod.

    摘要: An awl for providing entry into and subsequent penetration of a bone is disclosed. The awl features a first section which is straight and has a first end, an exterior end, and a cutting tip at its exterior end. The second section of the awl is a connection region which has a first end and a second end. The first end of the second section extends essentially normal from the first end of the first section. The third section provides an external reference for the direction of the cutting tip and extends from the second end of the second section in a direction essentially parallel to the first section, such that the oriention of the third section represents the orientation of the first section.
