Locking bone plate
ActiveUS20050015089A1Great flexibility of choiceJoint implantsExternal osteosynthesisTibial-plateau-leveling osteotomyEngineering
A bone plate(s) of complex form is provided, particularly suited to tibial plateau-leveling osteotomy and a distal femoral osteotomy. The bone plate has a main longitudinal axis, a bone-contacting bottom side (not shown) and a top side with at least three sets of overlapping holes which communicate through the plate from the top to the bottom side. The sets of overlapping holes define threaded apertures having multifaceted surfaces. When applied to a bone, two sets of such overlapping holes are located so as to lie on opposite sides of an osteotomy site and on the tibial plate; a third is aligned at approximately 60 degrees with the longitudinal axis. The configuration of this complex bone plate vary, depending on the physiology of the patient. An object of the invention is to provide an orthopaedic surgeon greater flexibility of choice in that a threaded peg providing secure fixing can be positioned at any interval along the bone plate, including at its extreme ends or on its elbow.

Methods and apparatuses for promoting fusion of vertebrae
Methods and apparatuses for promoting fusion of vertebrae are provided. The apparatuses comprise interconnecting plates that fixate vertebrae to each other and provide for a predetermined amount of subsidence where the fusion occurs. Allowing for this predetermined amount of subsidence increases bone to bone contact at the graft, which promotes fusion without having excessive settling of the two vertebrae onto the graft. The predetermined amount of subsidence is achieved by the placement of a plate spacer between each of two interconnecting plates when the plates are attached to the vertebrae. The plate spacer has a height equal to the maximum amount of subsidence desired. After affixing the plates to the vertebrae, the plate spacer is removed, leaving a space between the plates, which allows the vertebrae to subside by a distance equal to the height of the plate spacer.

Computer assisted surgery system using alternative energy technology
A method and apparatus for a computer assisted surgery (CAS) system using alternative energy tissue and bone alteration technology. The CAS system utilizes alternative energy technology which is a directed to a surgical instrument including an alteration or cutting tip. The tip may be in contact with the tissue or bone, or, alternatively, the tip may be distant from the tissue or bone and the energy is projected to the desired cut or alteration site. The CAS system recognizes the location of the tip relative to a desired alteration location or area and de-energizes or varies the energy level when the tip moves away from or out of the predetermined alteration location or path. The CAS system provides a method for altering or resecting bone, for example, in preparation for a prosthetic implant, or a method for altering tissue, for example, cauterizing blood vessels or bonding ligaments to bones.
