Abstract: Systems, tools, and screws for reducing a bone fracture are disclosed. In embodiments, the system comprises: a screw, a driver, a sleeve comprising a longitudinal bore configured to enable insertion of the driver through the sleeve, a locking mechanism configurable into a first state that locks the sleeve to the driver and a second state that unlocks the sleeve from the driver, and a retaining sleeve coupled to a first end of the driver and configured to couple to the screw. In the first state, the sleeve applies a compressive force while distal threads of the screw are driven into the bone while retaining proximal threads of the screw in the sleeve. After a desired compression is achieved, the locking mechanism is configured to the second state, allowing the proximal threads of the screw to be driven into the bone while maintaining application of the compressive force to the bone.

Abstract: The present disclosure provides for a system for mandibular distraction which includes a rod and a first pin clamp assembly coupled adjacent a first end of the rod. Furthermore, the first pin clamp assembly includes a first clamp. The system further includes a second pin clamp assembly which includes an advancement mechanism that moveably couples the second pin clamp assembly to the rod and a second clamp. Furthermore, a swivel joint is disposed between the advancement mechanism and the second clamp whereby the second clamp is enabled to rotate relative to the advancement mechanism.

Abstract: An improved fixation plate using at least a double helix screw as disclosed. The double helix screw may include alternate embodiments comprising three, four, or more threads. The helix thread screw intertwines with double helix thread in the screw hole of the fixation plate providing enhanced fixation to a fractured bone.

Abstract: A system for lockably engaging bone screws into a fixation plate may include a locking fixation plate including a threaded screw hole defined by an inner surface surrounding the threaded screw hole, the inner surface comprising an upper countersink and a threaded portion, the threaded portion comprising a pair of threads arranged in a double helix configuration, and a screw comprising a generally conical head tapering into a generally cylindrical shaft that ends at a tip and a single thread beginning near the tip and extending along the generally cylindrical shaft and onto the generally conical head, a thread height of the single thread being constant over a majority of the generally cylindrical shaft and tapering as the thread extends onto the head.

Abstract: A system for securing first and second bones together across a joint includes a fixation plate comprising a body having a longitudinal axis and first and second ends. A locking screw hole is disposed proximate to the first end. One or more attachment screw holes are disposed in the body. The system includes a screw comprising an elongate hollow body having openings at first and second ends and having a tip at the first end and a head at the second end.

Abstract: A system for fracture reduction includes a reduction plate for reducing a fracture between a first bone segment and a second bone segment. The reduction plate includes, on a first side of the reduction plate, a travel slot and a screw hole. The travel slot is configured to slidably engage a first positioning element that extends into the first bone segment through the travel slot and the first screw hole is configured to affix the first side of the reduction plate to the first bone segment. The reduction plate includes, on a second side of the reduction plate, an adjustment hole and a second screw hole. The adjustment hole is configured to engage a second positioning element that extends into the second bone segment through the adjustment hole and the second screw hole is configured to affix the second side of the reduction plate to the second bone segment.

Abstract: An apparatus for cutting a radial cut in a surgical plate includes a top jaw element, a bottom jaw element, a removable top insert operable to be coupled to the top jaw element, and a removable bottom insert operable to be coupled to the bottom jaw element, a first top radial cutting element and a second top radial cutting element coupled to the removable top insert, and a first bottom radial cutting element and a second bottom radial cutting element coupled to the removable bottom insert. The radial cutting elements provide a radial cut of the surgical plate. The apparatus also includes a first alignment post and a second alignment post coupled to the removable bottom insert. The alignment posts are operable to align the surgical plate on the removable bottom insert.

Abstract: A system for establishing a trajectory for a pilot hole includes a plate comprising a screw hole defined by a rim and an inner surface surrounding the screw hole, and a drill guide comprising a body having a guide well formed therein, the guide well defined by a wide opening in the body disposed opposite a narrow opening in the body and an interior surface that tapers from the wide opening to the narrow opening, the narrow opening surrounded by a tip of the body, the tip configured to fit into the screw hole.
