A convex spinal fusion interbody space device includes spaced apart superior and inferior abutment surfaces which are effectively medially convex. The peak of such convexity is displaced anteriorly of a central plane through the device. The spacer device has front to rear lateral concave surfaces and top to bottom lateral side channels that intersect with said convex surfaces. The spacer device has a height which is greater than the width of the device. The spacer device is implanted between a pair of adjacent vertebrae by insertion in a tipped-over orientation and then reoriented to an upright orientation for engagement by facing surfaces of the vertebrae. Fusion promoting bone material is packed between the vertebrae and about the spacer device subsequent to implantation.

A novel coplanar X-ray guided method and device for insertion of distal locking screws in intramedullary bone nails. The device has coplanar holes, which allow insertion of protective sleeves. Bone drill and bone screws can be inserted through the protective sleeves. Radiopaque target markers in the aiming arm enable the easy positioning of an X-ray source such that an X-ray beam is coplanar with the aiming arm transverse holes. After the X-ray source is accurately oriented, a single X-ray snapshot is enough to assess the exact distortion of the implanted intramedullary nail. The X-ray beam does not need to be coaxial with nail holes anymore. The aiming arm has a mobile portion and a fixed portion fastened to the nail, wherein said aiming arm can be adjusted, displacing the mobile portion over the fixed portion, to compensate for the distortion of the intramedullary nail after implanted. Once the aiming arm is precisely positioned, the aiming arm transverse holes and intramedullary nail holes are accurately aligned, protective sleeves are inserted through aiming arm holes, bone drills are drilled through the intramedullary nail holes and surrounding bone material, and bone screws are screwed, locking the intramedullary nail to the bone.

The invention relates to a spinal implant consisting of a bone material body which is embodied in a curved manner in its longitudinal direction and is provided with coupling means.

A minimally invasive interbody device assembly that includes an interbody device that restores the disc space height between two vertebrae and an instrument detachably coupled to the interbody device for positioning the device in the disc space and delivering bone material to the disc space that is distributed on both sides of the interbody device. The device is inserted into the disc space using the instrument in a direction so that the wide dimension of the device is substantially parallel to the body of the vertebrae. The device is then rotated by the instrument so that the wide dimension of the device becomes perpendicular to the vertebral body so as to cause the disc space height to be restored. Bone graft material is then forced down the instrument so that the bone graft material is distributed on both sides of the device. The instrument is then detached from the device.

A collection device for collecting bone material during a spinal fusion surgical procedure so that the bone material can later be used as a graft material for the fusion procedure. The device includes a container that collects the bone and other material that is removed from the patient during the surgical procedure through a suction hose. The device includes a plunger having a filter plate sealed to the inside of the container. The plunger is pushed down into the collected material in the container so that blood and other liquids are forced through the plate to be separated from the bone material. A cover at the bottom of the container can be removed to remove the collected bone material.

Osteogenic bone implant compositions that approximate the chemical composition of natural bone are provided. The organic component of these implant compositions is osteoinductive despite the presence of the inorganic component and, further, is present in an amount sufficient to maximize the regenerative capabilities of the implant without compromising its formability and mechanical strength. The composition may be an osteoinductive powder, including demineralized bone matrix (DBM) particles, a calcium phosphate powder, and, optionally, a biocompatible cohesiveness agent. The powder may be combined with a physiologically-acceptable fluid to produce a formable, osteoinductive paste that self-hardens to form a poorly crystalline apatitic (PCA) calcium phosphate having significant compressive strength. The bone implant materials retain their cohesiveness when introduced at an implant site and are remodeled into bone in vivo. Methods for using these implant materials to repair damaged bone and a method of assaying the content of DBM particles, by weight, in a bone implant material are also provided.

An attachment surface for an implantable device has an irregular pattern formed through a process including masking, chemical or electrochemical etching, blasting and debris removal steps. Surface material is removed from the implant surface without stress on the adjoining material and the process provides fully dimensional fillet radii at the base of the surface irregularities. This irregular surface is adapted to receive the ingrowth of bone material and to provide a strong anchor for that bone material which is resistant to cracking or breaking. The surface is prepared through an etching process which utilizes the random application of a maskant and subsequent etching in areas unprotected by the maskant. This chemical etching process is repeated a number of times as necessitated by the nature of the irregularities required in the surface. The blasting and debris removal steps produce microfeatures on the surface that enhance the ingrowth of bone material.
