    Abstract: A locking fastener for use with a bone plate. The fastener has threads on its shank to engage bone and threads on its head to engage the internal threads of the bone plate. The threads in the head may have a constant major diameter and a tapered minor diameter that creates a radial interference fit. The threads in the head may also have a variable pitch that creates an axial interference fit. The head may have a low profile to reduce soft tissue irritation.

    Abstract: A compression hip screw plate for a hip screw system used to compress a proximal femur having a shaft with a lateral aspect and a neck extending from the shaft at an anteverted angle, both of which follow the anatomical contours of the proximal femur. The compression hip screw plate may include a side plate having a face side attachable to the lateral aspect of the shaft of the proximal femur; and a barrel having a first end extendable through the lateral aspect of the shaft of the proximal femur and into the neck of the proximal femur, and having a second end attached to the side plate with the first end extending away from the face side of the barrel at an anteverted angle. The compression hip screw plate may include a side plate with an anterior bow to match the natural femur.

    Abstract: Modular surgical instrumentation and a method of using same is provided, according to the invention. The instrumentation comprises a first bracket defining a generally U-shaped structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an elongated central opening appointed to expose a selected area of the resected femur, including a curved track for guiding a first shaping tool along a predetermined path for controlled shaping of a curved patellar groove in a portion of the selected area exposed through the opening. A second bracket defines a linear slotted bore extending generally parallel to the long axis of the femur for guiding a second shaping tool to form a relatively deep recess accommodating an intercondylar stabilizing housing of a knee implant. The second bracket has an internal surface defining a shape adapted for releasable engagement with the curved track, including mechanism for accurately aligning the slotted bore relative to the opening while forming the recess. The method of the invention comprises the steps of seating the first bracket described above on the distal aspect of the resected femur and moving the first shaping tool along the curved track to form a patellar groove in a selected area thereof. The first shaping tool is then withdrawn and, leaving the first bracket in place, the second bracket described above is seated on the curved track so that the slotted bore of the second bracket is accurately aligned with the opening of the first bracket, after which a second shaping tool is introduced through the bore to form a recess accommodating the intercondylar-stabilizing housing of the implant.

    Abstract: PROBLEM TO BE SOLVED: To provide a perforating pin and equipment for perforation with which an accurate piercing region and piercing direction of a guiding pin can be easily specified at the neck of the femur or its surroundings and an advancing situation of the perforating pin can be confirmed when the perforating pin is pierced.SOLUTION: The guide 1 for the perforating pin includes a main body section 2 which is equipped with a contacting section 8, a guiding channel 3 for the perforating pin and an operation section 9, a first advancing direction of the perforating pin displaying section 5 with which the advancing direction of the perforating pin 10 inserted in the guiding channel 3 can be confirmed by X-ray fluoroscopy, and a second advancing direction of the perforating pin displaying section 6 with which the advancing direction of the perforating pin 10 inserted in the guiding channel 3 can be confirmed by X-ray fluoroscopy from the different direction than the first advancing direction of the perforating pin displaying section 5. The bone perforating pin 10 can be confirmed by X-ray fluoroscopy with the first and the second advancing direction of the perforating pin displaying sections 5 and 6 while the perforating pin 10 inserted in the guiding channel 3 is superimposed on the displaying sections 5 and 6.

    Abstract: According to the invention, there is provided a trial implant and method of using same. The implant comprises a modular bracket defining a structure having an internal surface adapted to be seated on the distal aspect of a resected femur bone and an external surface with a shape resembling the normal distal condyle of the femur. The bracket has a elongated central opening appointed to expose the resected bone of the femur, including a pair of tracks for guiding a tool along a predetermined path for controlled shaping of a patellar groove in the bone exposed through the opening. An end mill guide cooperates with the bracket to receive another tool to form a deep recess for accommodating a posterior-stabilizing housing. After the patellar track is formed, the external surface of the bracket articulates with a proximal aspect of the tibia during interoperative trial reduction of the knee joint. Removal of the bracket from the resected bone is unnecessary following the shaping steps prior to performing the trial reduction.

    Abstract: The present invention provides a cutting guide for ostectomy of the medial and lateral tibial surface during knee surgery. The cutting guide comprises a guide block including an axial opening defined along the longitudinal axis of the tibial canal. The guide block being adapted for attachment to a tibial trial base including alignment holes for locating the proper degree of rotational alignment of the tibial trial base with respect to the longitudinal axis of the tibia to assure the proper varus-valgus orientation and anterior-posterior slope of the resected tibial surface with respect to the femur. A pair of blade slots are provided for guiding a cutting tool for making a wedge-shaped resection of the tibia to accommodate a tibial tray component having a preselected internal distal surface corresponding to that of the resected tibia. The blade slots are pivotally mounted for selectively adjusting the angular alignment of the blade slots with respect to the lateral-medial axis perpendicular to the longitudinal axis of the tibia.
