Abstract: A flexible inramedullary fixation rod for fractured bones is provided having a length sufficient to extend a substantial distance on either side of a diaphyseal fracture site and a substantially circular core with radially disposed fins extending substantially along the full length thereof. The radii of the core and fins are such that the rod can pass through the bone's medullary canal and engage the inner, or endosteal, surface of the bone along line contacts, thereby allowing normal endosteal healing and intramedullary revascularization. The rod is constructed of a flexible, bio-compatible material, such as titanium, stainless steel, resorbable polymers (e.g., polylactic acid) or carbon fiber-polysulfone. The radii of the fins are selected to be substantially equal to the minimum radius of the medullary canal.

Abstract: A modular femoral internal implant system for use in the treatment of femoral disorders resulting from injury, disease or congenital defect includes at least three interconnectable components: 1) an elongated epiphyseal/metaphyseal implant, 2) an intramedullary rod and 3) an angled side plate having an elongated plate portion adapted to be secured to the outer cortical wall and a hollow sleeve adapted to extend into the femur. The epiphyseal/metaphyseal implant can be connected to either the angled side plate or the intramedullary rod. The system may also include an elongated bone plate connectable to the angled side plate, one or more additional epiphyseal/metaphyseal implants of variable length, an additional angled side plate, a distal buttress plate connectable to the elongated bone plate, and a plurality of bone screws of a universal design. Preferably, many or all of the components of the system are made of an inert, resilient titanium-base alloy.

Abstract: A hollow one-piece intramedullary nail for the tibia has a proximal end segment, a bent intermediate segment and a distal end segment. The central axis of the proximal end segment diverges from the central axis of the distal end segment at an angle of about 11.degree.; the proximal end segment and the intermediate segment have a total length in the range of about 105 mm; and the sum of the length of the proximal end segment and half of the length of the intermediate segment corresponds to about one third of the total length of the nail.

Abstract: A tibia medullary pin for the treatment of lower-leg fractures of all kinds has an anterior half (1), a posterior half (2), a proximal end segment (3), and a distal end segment (4), with the longitudinal axes (5;6) of the two end segments (3;4) forming in the antero-posterior plane an angle of 5.degree.-13.degree. with each other. The proximal end segment (3) has a cross-section area (7) that is trigonal in both the anterior (1) and the posterior (2) halves, and overall is approximately rhombic, while the distal end segment (4) has a cross-section area (8) that is approximately trigonal in the anterior half (1) and is approximately semi-spherical in the posterior half (2).

Abstract: An instrument set is provided for driving flexible bone implants into fractured long bones and then extracting them after the bones have mended, the set having a plurality of tools adapted to be held individually and interchangeably in a multi-functional handle, with specific tools being used to insert specific implants choosen according to the type and location of the fracture.

Abstract: An osteosynthetic fixation plate comprising a retaining plate and a helically twisted blade extending therefrom, for use in treatment of fractures to the neck of the femur.

Abstract: A femur sliding screw plate is improved by adding flanges or wings on either side of a central portion, the flanges extending at least partially around the femur shaft. Preferrably, the flanges are provided integral to a centrally raised part which fits over a portion of the leg of a basic screw plate. Screw holes in the sliding screw plate align with screw holes in the basic screw plate and the sliding screw plate is attached to the basic screw plate and each screw plate is attached to the femur by common screws. The flanges each have screw holes, offset from the screw holes in the centralloy raised portion, screws being used to secure the flanges to outlying portions of the femur shaft in order to more fully consolidate fragments of the fractured femur. Alternatively a screw plate is provided with integral flanges extending from the leg of the screw plate.

Abstract: The instant invention provides both a device and a method for treatment of a fractured neck of a femur. The device is such that it is inserted inside the broken femur and urges the two halves together so that the bone will unite and heal by natural growth processes. Unlike its predecessor the instant invention can be withdrawn from the femur once sufficient healing has taken place and the bone will continue to repair itself for all practical purposes to an extent as if no fracture had occurred.

Abstract: A set of flexible implants for repair of femur fractures includes a short implant which is of flattened S shape and is dimensioned to extend generally upwardly from a point below the upper condyle through the neck and into the head of the femur, an intermediate length pin which is bowed to be turned downwardly and to extend from a region below the short pin through the neck and into the head of the femur, and a long pin which is bowed and extends the length of the femur from the region of the lower condyle into the upper condyle or the head of the femur. Short and intermediate length pins have eyes adapted to lie against the shank of the femur and are held in place by bone nails or screws. The lower end of the long pin has an S bend connected to a spade formation conforming to the curvature of the region of the long pin.
