Lag Screws in Mandibular Fractures

It is widely established that lag screw osteosynthesis in the management of mandibular fractures provides the maximum amount of fracture stabilization and compression utilizing a minimal amount of hardware in the shortest operative times. Yet the major disadvantage of the lag screw technique is that it is the most technique-sensitive of all the fixation modalities. Hence, the introduction of the new KLS-Martin Lag Screw System which simplifies the traditional technique in a completely revolutionary manner.

The KLS-Martin System provides the means to ensure accurate and predictable placement of lag screws for many mandibular fractures. The System provides instruments specifically designed to assist in the reduction and fixation of these fractures. Through use of our unique and proprietary Drill Guide, Stepped Drill Bit and Adjustable Countersink; the pilot hole, gliding hole and countersink can all be prepared with just one pass of the drill. The Drill Guide, along with its Adjustable Pointer, can also function as an external depth gauge to select the appropriate size Lag Screw. The KLS-Martin Lag Screws are of an entirely distinctive design and are composed of high strength Titanium Alloy. Our Screws feature a self-retaining center drive head, a biconcave countersink (which increases the surface area of the compression component of the screw while directing the compressive forces towards the center of the screw), a polished non-threaded gliding shaft and a single fluted self-tapping end. When utilized properly, the elegant technique developed for the KLS-Martin System will become the primary mode of rigid internal fixation for non-comminuted mandibular fractures.
