A method according to the present disclosure may include determining a load to be supported across separated bone regions by a bridge region of a bone plate. The method may further include determining an acceptable cut force (CF) for the bridge region, determining a cross-sectional area (a) of the bridge region based on the determined load, and determining a height (h) and a width (w) of the bridge region. A bone plate may be provided including a bridge region having the height (h) and width (w) for securing the separated bone regions.

Method and apparatus for bone fracture fixation

An elongated plate for coupling severed bone regions comprising at least one bridge region, the at least one bridge region terminating in at least two bone fixation regions. The at least two bone fixation regions each contain at least one aperture for receiving a suitable fastening device for securing the elongated plate to the bone regions to be coupled. The bridge region may be configured so as to be easily severed by a suitable severing device such as surgical scissors. The elongated plate and fastening device may be formed from a bio-compatible or bio-resorbable material.

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.

Cranial clamp and method for fixating a bone plate

This invention relates to a set of surgical instruments for use in reattachment of a cranial flap using a cranial clamp having a base, a cap and a stem. The set of surgical instruments includes an applier instrument, a stem holder instrument and a stem cutter instrument. The applier instrument slidably receives a portion of the stem and moves the cap relative to the base. The applier instrument includes a handle, a trigger and a barrel configured as a gun-style instrument, as well as includes an engagement mechanism having a contoured surface that matingly engages a contoured surface on a portion of the stem. The stem holder instrument engages and holds a portion of the stem. The stem holder instrument includes a pair of handles and a lock mechanism that may be locked upon squeezing a pair of handles once and be opened upon squeezing the pair of handles once again. The stem cutter instrument removes a portion of the stem from the cranial clamp. The stem cutter instrument includes a capture mechanism which retains a sheared portion of the stem.

A system for mandibular reconstruction generally includes an elongated locking plate having a plurality of internally threaded apertures and a plurality of fasteners. Each fastener includes a main body portion having an upper threaded shaft and a lower threaded shaft. The lower threaded shaft is adapted to engage the mandible. Each fastener further includes a removable head portion internally threaded for engaging the upper shaft portion and externally threaded for engaging a selected one of the internally threaded apertures of the locking plate. In the preferred embodiment, the thread leads of the head portion and lower shaft of the main body portion are identical. A method of mandibular osteosynthesis utilizes the system of osteosynthesis and generally comprises the steps of temporarily securing the elongated locking plate to the mandible with at least one fastener by engaging the threads of the lower portion with the mandible and threadably engaging the head with the locking plate, unthreading the head portion from the main body of the fastener to thereby allow displacement of the locking plate from the mandible without removing the fasteners from the mandible, performing a surgical procedure (e.g., removal of a cancerous growth), and re-securing the elongated plate to the fastener with the removable head portion.

Method and apparatus for mandibular osteosynthesis

A method and apparatus for performing pectus excavatum repair on a deformed sternum. The apparatus includes an elongated pectus bar having a first end and a second end. The elongated pectus bar provides a minimum bendable strength of about 65 in-lbs or a minimum material yield strength of 35.times.10.sup.6 psi or a minimum bendable stiffness of about 1000 lb-in.sup.2. The elongated pectus bar is shaped into a convexly curved pectus bar. The convexly curved bar is passed under the deformed sternum with the convexity facing posteriorly. The elongated pectus bar is then rotated so that the convexity faces anteriorly such that the deformed sternum is raised into a desired position.

Method and apparatus for performing pectus excavatum repair

The invention relates to an apparatus and method for stabilization of a shunt relative to a bone. The apparatus includes a body member and a plurality of attachment members forming a part of the body member. Each of the attachment members are operable to receive a bone screw so as to secure the body member to the bone. A plurality of movable fingers are movably attached to the body member. The plurality of movable fingers are adapted to engage and stabilize various size shunts relative to the bone.

This invention relates to a formable mesh for use in osteosynthesis and a method of use therefore. The formable mesh includes a plurality of orifice plates linked together by a plurality of connecting arms. The plurality of orifice plates includes a first orifice plate having at least six radially offset connecting arms. Each of the radially offset connecting arms includes a first end coupled to the first orifice plate and a second end coupled to a second orifice. Upon rotation of the first orifice plate in a first direction, each of the second orifice plates is retracted relative to the first orifice plate. Upon rotation of the first orifice plate in a second direction, each of the second orifice plates is extended relative to the first orifice plate.

Formable mesh

The invention relates to a multi-configurable plating system for use in osteosynthesis and a method therefore. The multi-configurable plating system includes a multi-configurable plate formed from a plurality of annular mounting tabs linked together by a plurality of linking members. The plurality of annular mounting tabs and the plurality of linking members form a separable straight plate, a separable L-shaped plate and a separable T-shaped plate. The separable straight plate is connected to the multi-configurable plate by no more than two linking members. The separable L-shaped plate is connected to the multi-configurable plate by no more than two linking members. The separable T-shaped plate is connected to the multi-configurable plate by no more than three linking members. This enables a user to easily separate the separable straight plate, the separable L-shaped plate and the separable T-shaped plate from the multi-configurable plate by cutting along the appropriate linking members.

Multi-configurable plating system

A self-retaining screwdriver having a plurality of diametrically opposed, radially extending blades on its tip for engagement with corresponding slots of a screw or other fastener, wherein the blades vary radially in thickness. The screwdriver also includes diametrically opposed, radially extending blades of constant thickness arranged perpendicular to the blades of radially varying thickness. Tapered blades having a thickness which increases with distance from the screwdriver axis are disclosed in one embodiment in which the blades also have a convex end surface, for use with a screw having a convex head.
