Abstract: A spine fixation assembly has a polyaxial spine screw rod holder for a first spine rod and a second rod holder for a second spine rod, the second rod holder is linked to the polyaxial spine screw rod holder via a connector, the connector extending radially outward from the polyaxial spine screw rod holder such that the second rod holder is spatially separated from and offset relative to the polyaxial spine screw rod holder. The polyaxial spine screw rod holder defines a first rod seat that holds the first spine rod. The first spine rod has a first longitudinal axis. The second rod holder defines a second rod seat that holds a second spine rod. The second rod has a second longitudinal axis. The second rod holder is oriented relative to the polyaxial spine screw rod holder by the connector at an offset (angle).

Abstract: A spinal plate system that maintains intervertebral spacing and spinal stability is provided. One embodiment includes a spacer for establishing an initial condition of an adjustable spinal device. The spacer includes a first coupling portion configured to couple selectively with a first segment of the adjustable spinal device, a second coupling portion configured to couple selectively with a second segment of the adjustable spinal device, and a spacer body extending between the first coupling portion and the second coupling portion. The spacer prevents movement of the first segment of the spinal device relative to the second segment when the first coupling portion is coupled selectively with the first segment and the second coupling portion is coupled selectively with the second segment.

Abstract: A spinal plate system that maintains intervertebral spacing and spinal stability is provided. In an embodiment, a spinal compression plate may include two or more plates coupled together form an adjustable-length plate. Compression of a spinal compression plate movement may mimic natural settling of bones in a spine and/or distribute at least a portion of a vertebral load to an implant positioned between two vertebrae. Maintaining at least a portion of the vertebral load on an insert may increase bone growth and increase fusion between an implant and surrounding vertebrae.

Abstract: A bone plate system is provided which maintains intervertebral spacing and stability of a spine. In an embodiment, a bone plate system may include a base plate with an opening through which the fastener may be positioned to allow the fastener to be inserted into a human bone at a desired angle relative to the plate. Some embodiments of a bone plate system may include a base plate and an extender plate. An extender plate may be coupled to a base plate while the base plate is coupled to the bone.

Abstract: A spinal implant is provided which maintains intervertebral spacing and stability within the spine. In some embodiments, two or more spinal implants may interlock to form a spinal stabilization system. Spinal implants may interlock using protrusions, indentations, teeth, and/or grooves. In an embodiment, an opening may be positioned in the spinal implant to fuse the spinal implant to surrounding bone tissue. Bone growth through the opening may be increased by using a removable bone growth stimulating insert in the opening. A spinal implant may be constructed of biocompatible material, for example, bone, metal, and/or polymers.

Abstract: A patella recession instrument (10) and method provides a guide for producing an oval, tri-oval, or elliptically shaped recess on the posterior surface of the osteotomized patella for receiving a similarly shaped backing portion of a patellar implant. The apparatus includes a guide bushing (12) and a bushing positioning mechanism (14) for securing the bushing against the posterior of the osteotomized patella, with a guide opening (54) formed through the bushing covering the total area to be recessed. A reamer guide structure, which may be a separate structure (16) received in the bushing guide opening (54) or integrally formed with the bushing (12), receives one or more rotary reamer tools (18) in a plurality of reaming positions. The cutting face (80) of the rotary reamer tool (18) in each different reaming position covers a different portion of the total area to be recessed.
