Apparatus and methods of fixating bone include repairing or remodeling a hard tissue defect with a composite bone structure. The composite bone structure includes at least two hard tissues or bones and a scaffold material fixed together by an adhesive component. The apparatus and methods include positioning the hard tissues/bones, conforming the scaffold material to at least a portion of a surface of the hard tissues/bones, contacting the adhesive component with the hard tissues/bones and the scaffold material, and changing the material state of the adhesive component to another material state at which the adhesive component fixes together the hard tissues/bones and the scaffold material, thereby forming a composite bone structure having a desired rigidity.

An assembly for surgically treating a chest-wall deformity may include an implantable stabilizer member, an implantable pectus bar and an implantable stopping member. The implantable stabilizer member may include first and second base parts and a channel defined by the first and second base parts. The stabilizer member may include first and second retaining bars extending between the first and second base parts and traversing the channel. The first and second base parts may be adapted to be secured to tissue of the chest wall. The implantable pectus bar may be receivable within the channel of the stabilizer member. The implantable stopping member may be adapted to be engaged with the pectus bar between the first and second retaining bars after the pectus bar is inserted into the channel to restrict movement of the pectus bar relative to the tissue.

A closure system may secure a first bone portion to a second bone portion. The closure system may include a bracket, a band and a tensioning device. The bracket may include a first portion adapted to engage the first bone portion and a second portion adapted to engage the second bone portion. The band may engage the bracket and may be adapted to be looped around the first and second bone portions. The tensioning device may include a body and a threaded member. The threaded member may be received in the body and may engage the band such that rotation of the threaded member relative to the body moves a first end of the band relative to a second end of the band.

A surgical device of a drill/driver with bit recognition to set a desired application mode and a method of utilization thereof is provided. Various operating modes of the drill/driver are automatically set by a sensor which recognizes the bit applied to the drill/driver. A method of utilizing the drill/driver allows the drill driver to apply surgical screws at very high speeds while automatically preventing excessive torque levels that would strip out the surgical screw from the patient's bone.

A surgical implant may include a first implant member, a second implant member and a fastener. The first implant member may include a first aperture having first and second ends. The first aperture may include a female threaded portion and a barrier member disposed between the first and second ends and extending radially inward into the first aperture. The female threaded portion may be disposed between the first end and the barrier member. The second implant member may include a second aperture. The fastener may extend at least partially through the first and second apertures and may include a head portion and a shaft portion. The shaft portion may include a flexible tab and a male threaded portion engaging the female threaded portion. The male threaded portion may be disposed between the flexible tab and the head portion.
