Walter Lorenz Surgical, Inc. - Jacksonville FL

International Classification:

A61B 1784

US Classification:

606 72, 606 73, 606213

Abstract:

A clamp assembly for repairing a bone defect according to the invention includes a base, a cap opposing the base, and a post connecting the cap and the base in a fastening position on adjacent bone plate and surrounding cranium. The clamp assembly may further include an applier interacting with the post to position the cap and base in the fastening position. A method according to the invention includes placing the base and cap on opposing internal and external surfaces of the bone plate, with a portion of each of the base and cap overlapping a border of junction between the bone plate and surrounding bone. The post is rotated to bring the base and cap to the fastening position. The method may further include removing a distal portion of the post projecting from the cap and leaving a proximal portion of the post projecting from the cap and which can be deformed to secure the base and cap in the fastening position.

Abstract:

A driver assembly may include a fastener and a driver. The fastener may have a head with upper and lower surfaces. An engagement portion may be located in the upper surface proximate a perimeter portion thereof. A shank may extend from the lower surface of the head and a breakaway portion may extend from the upper surface of the head. The driver may include a shaft having a body with a first end having a fastener-engaging portion. The fastener-engaging portion may have an outer driving geometry engaged with the engagement portion of the fastener when in an engaged position. The first end may further include an opening therein. The opening may receive at least a portion of the breakaway portion when in the engaged position.

US Classification:

606280, 606283, 606284, 606286

Abstract:

The present invention relates to a series of orthopedic plates for use in repair of a clavicle. The plate has a Y-shaped profile or an X-shaped profile which includes an elongate central trunk with a complex contour and wither one or two terminal pairs of arms that have a first arm and a second arm that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other to provide for multiplanar fixation but which do not impinge.

Abstract:

The present invention relates to an orthopedic plate for use in repair of a fibula. The plate has a Y-shaped profile which has the contour of a spoon where the bowl includes a terminal pair of arms that form differing angles and lengths relative to the trunk portion of the plate. The arms include locking screw holes where the screws converge toward each other, but do not impinge so as to provide-multiplanar fixation.

US Classification:

606280, 606906

Abstract:

The present invention is a MTP plate that has a first embodiment with a profile having bilateral mirror symmetry of the about a transverse plane with an angle of about 5 for dorsiflexion and an angle of about 10 for valgus. Both ends of the plate include a central arm having a slot for compression and two offset arms having offset ears with locking screw holes that provide for multiplanar compressive fixation. The bone contacting surface of the plate is radiused to allow the plate to be in snug contact with the bone. In a second embodiment of the plate for revision surgery, the proximal end of the plate includes a metatarsal extension and the plate has a central locking hole for securing bone graft.

Abstract:

A cannulated compression screw is used as an orthopedic implant and has a threaded distal end with an insertion tip that includes at least one and preferably two, three or four flutes to allow the screw to be self-tapping. Optionally, the screw also includes one or more reverse cutting flutes proximal to the insertion tip. The distal threads are cancellous threads having a generally constant minor diameter and a generally constant major diameter and a generally constant thread pitch. An intermediate portion of the screw is non-threaded and the proximal end includes a compression wedge or taper that has at least one, and preferably two to five flutes that terminate before the top of the screw. The proximal end further includes a radiused bevel to the terminal surface that includes a hexagonal torque driving recess. The diameter of the non-threaded shaft section is constant distal from the compression wedge to the distal tip where it defines the minor diameter of the threaded portion.
