The invention relates to a reconstruction or fracture plate for bridging a discontinuity in a patient's long bone, such as a femur and has a central portion for placement over the bone discontinuity, a first end portion having a dual-tapered width and thickness profile having a first plurality of screw holes and a second end portion defining a second plurality of screw holes. The first and second plurality of screw holes each have asymmetrically arrayed centerlines relative to plate longitudinal and transversal axes and the screw holes may have asymetrically arrayed centerlines relative to each other. Both the first and second end portions may have dual-tapered profiles.

Dual-taper, asymmetric hole placement in reconstruction and fracture

An improved artificial ligament is tubular in overall configuration with flared ends, which have a graduated pore density to permit controlled hard and soft tissue ingrowth, and a central portion which prevents tissue ingrowth. The central section of the ligament is elongatable along its longitudinal axis to permit the needed elasticity in use.
