  • Publication number: 20020165543
    Abstract: By providing components securable to anchor pins or screws of different diameters as well as providing clamps which hold associated pins in any position during adjustments, an external fixation or adjustable frame structure is provided which is capable of being quickly and easily assembled in any desired configuration. In the present invention, the frame structure is retained in any assembled configuration in order to allow final adjustments to be made, prior to the final securement of the frame assembly in the precisely desired configuration by closure of each clamp member. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members.

  • Publication number: 20020065516
    Abstract: An orthopaedic bone plate is coupled to a bone having an enlarged head at one end thereof which is attached to a shaft. The bone plate includes an elongate portion a flared portion and an intermediate portion. The elongate portion is attachable to the bone shaft using a plurality of bone screws. The elongate portion generally defines a longitudinal axis. The flared portion is attachable to the bone head using at least one bone screw. The intermediate portion interconnects the elongate portion and the flared portion. The intermediate portion is structured and arranged to allow the elongate portion and the flared portion to move relative to each other in a direction transverse to the longitudinal, axis when the elongate portion and the flared portion are attached to the bone.

  • Patent number: 5499984
    Abstract: A medullary reaming system includes a flexible, hollow, tubular shaft formed of a nickel-titanium alloy having one end coupled to a rotary drive and having the other end coupled to a cutting head by means of a male connector on the shaft engageable in a female connector on the head. The female connector is a tubular shank with diametrically opposed slots in the outer surface thereof, while the male connector has flexible arms with latch tabs engageable in the slots to latch the head to the shaft. A support has a plurality of notches for respectively storing cutting heads. The head shank is received in the notch with the notch edges received in the shank slots, so that when the male connector on the shaft is inserted into the shank the notch edges prevent latching of the head to the shaft until the head is removed from the support.

  • Patent number: 5034013
    Abstract: An intramedullary nail is disclosed having a tubular elongated body that includes a proximal head portion, an intermediate portion and a distal end portion. The intermediate portion has a longitudinal slot along one side thereof, a groove coextensive with a portion of the slot, and three other grooves spaced about the circumference of the body. This construction provides more desirable flexibility and allows improved revascularization about the nail. The nail is formed of a rod material and the slot and grooves are machined therein to the desired depth and shape.
