Signus launches the Diplomat pedicle screw system


Signus has launched the Diplomat pedicle screw system. Developed in cooperation with international spine experts, the Diplomat system is a posterior fixation system that provides user-friendly and reliable instrumentation for all spine treatments.

“The main focus of Diplomat is the optimised balance between clinical performance and user-friendliness,” says Signus managing director, Uwe Siedler. The system combines maximal clinical efficiency with all the important properties required for optimal patient treatment.

The pedicle screws are a modular two-piece implant: depending on the indication and surgical application, the pedicle screws can be assembled as required with the appropriate tulips. If necessary, the tulips can be removed and replaced in situ during surgery. A very low tulip profile of only 14.9mm guarantees optimal anatomical alignment and prevents any protrusion of the tulip even in slim or young patients. The patented Elastolok locking mechanism ensures the strength of the screw/tulip connection. The Diplomat system provides optimal flexibility and efficiency thanks to these features. The system offers not only a high level of safety but also ease of handling during surgery.

Because all the pedicle screws are cannulated, as well as being fenestrated from a diameter of 5.5mm, the surgeon can perform augmentation at any time, allowing intraoperative issues to be more easily resolved. The screw-cannula diameter of 1.9mm also allows the use of stronger guide wires, which noticeably stabilises the insertion of the pedicle screw during minimally invasive procedures. The Diplomat pedicle screws also have a self-tapping double thread that provides the best possible fixation and perfect anchoring in the bone. The high thread pitch enables faster insertion which considerably shortens surgery time.

Signus provides a complete selection of Diplomat system components, all with a sophisticated design. When treating long segments of the spine, innovative telescopic cross-connectors secure the instrumentation while parallel connectors allow for simple subsequent treatments with varying rod diameters. The system rods are available both as titanium and as cobalt-chrome components to suit different demands.

Despite the versatility of the instruments, in routine clinical use the outlay and costs remain reasonable. Diplomat is arranged in only two containers, which makes for a significant reduction in time spent on logistics and reprocessing in the hospital.
