Abstract: An insertion guide for guiding a fastener having a head and a shaft. The insertion guide includes a sidewall constructed of a biocompatible material having an entrance end, an exit end, and a cavity extending from the entrance end to the exit end. The sidewall has a guide portion and a fastener connector portion. The guide portion of the sidewall extends from the entrance end toward the exit end, and the fastener connector portion of the sidewall extends from the exit end toward the guide portion. The sidewall in the guide portion is configured such that the cavity has a first cross-sectional distance greater than the head of the fastener. The sidewall in the fastener connector portion has a second cross-sectional distance greater than the shaft, and less than the head.

Abstract: The presently disclosed and claimed inventive concept(s) relates generally to the field of bone plates for the reduction and fixation of bone fractures, in particular, the presently disclosed and claimed inventive concept(s) relates to a quadrilateral surface bone plate for the fixation of acetabular fractures having at least one securing port therein and methods of making and using same.

Abstract: A screw guide includes a first end, a second end spaced from the first end, a guide body that extends from the first end to the second end, and a guide hole that extends through the guide body. The guide body includes a first guide surface and a second guide surface, the first guide surface defines a first opening of the guide hole, and the second guide surface is spaced from the first guide surface in a first guide direction. The second guide surface defines a second opening of the guide hole, the guide body includes a leg portion that extends from the second guide surface in the first guide direction such that the leg portion is spaced from the second opening in a second guide direction that is perpendicular to the first guide direction.

Abstract: The present invention is directed to an interspinous spacer assembly for implantation and/or affixation between spinous processes of adjacent superior and inferior vertebrae and associated tools and methods for stabilizing the human spine. The interspinous spacer assembly includes a spacer body, a first lateral plate, a second lateral plate and a locking mechanism extending through a channel provided in the spacer body and coupling the first and second lateral plates to the spacer body.

Abstract: Facet fusion implants with various body geometries are provided. The bodies of the facet fusion implants can be configured to minimize migration of the implants when the implants are inserted into facet joints. Surgical methods and accompanying surgical instrumentation for inserting the facet fusion implants into facet joints are provided.

Abstract: Disclosed is an axial and rotational stopping device for use when creating threads in a predrilled pilot hole or inserting an allograft bony void filler or synthetic implant into a threaded hole. The device can also provide consistent depth control for drilling a pilot hole, tapping the hole to create threads, and implanting an allograft bony void filler or synthetic implant while preventing damage to the threads in the tapped hole that would be caused by continuing to rotate a tap once the depth stop has been reached and the tap can no longer advance in the axial direction, as well as preventing damage to the threads in the tapped hole, the threads on the mating allograft bony void filler or synthetic implant, and the drive features on either the driver instrument or the allograft bony void filler or synthetic implant.

Abstract: A fixation assembly is described comprising at least two plates, one of which may be a contoured plate and one of which may be a securing plate. The contoured plate may have a plurality of teeth, and the securing plate may have a resilient securing element. The teeth may be arranged so that the resilient securing element encounters progressive resistance as the plates are compressed.
