Threaded Reduction Tools

As a result of requests from our surgeons asking for a tool to aid in the reduction of bone fragments in craniomaxillofacial procedures the new threaded reduction tools have been developed. These instruments allow for easy percutaneous manipulation and reduction of bone fragments in fractures of the zygomaticomaxillary complex (ZMC).

The threaded reduction tool comes in three configurations that are all included in the set:

  • One 2.4mm version of the threaded reduction tool, which will be sterile-packed for single use only. The 2.4mm thread is self-drilling, thus eliminating the need to pre-drill. If pre-drilling is required, the use of the additionally available 1.8mm drill guide is recommended. The device has a ball stop to hold the soft tissue away while manipulating the bone fragments. This tool is 78mm in length.
  • Two 3.5mm self-tapping reduction tools, which can be reused. They are available in two sizes: One with a length of 78mm and a shorter 43mm version. For these devices the set also contains a 2.4mm drill bit in corresponding color code as well as a respective drill guide to protect the soft tissue while pre-drilling.

All threaded reduction tools are equipped with a hex drive coupling. This allows mounting them onto the new t-handle with hex coupling, which was developed as the main control device for the reduction tools. One key requirement in the development process that was met was that attaching and detaching of the reduction tools needs to be uncomplicated. Therefore the surgeon now has the option or to removal of the t-handle after reduction for better visualization of the fracture during surgery. Furthermore he reduction tools can be inserted with a standard screwdriver handle if preferred.

The t-handle is designed to provide the surgeon with sufficient leverage to reduce even complex bone fractures. To ensure easy cleaning after use, small drainage holes have been applied.
