CBS (Compression Bone Screw) Tool Set or Screw Set

With its different screw diameters and lengths, the cannulated CBS system enables a wide range of indications for the treatment of fractures in small animal orthopedics and trauma surgery. CBS stands for Compression Bone Screw and, in its function as a lag screw, enables the compression of two bone fragments.

In contrast to conventional cortex tension screws, which are inserted using a smaller pilot or threaded hole in the distant cortex and a larger spacing or sliding hole in the nearby cortex, the cannulated CBS is screwed in using a KIRSCHNER guide wire. The principle operation of a lag screw with compression is achieved because the threads on the head and the shaft end have different pitches. This gradient difference causes the interosseous compression. The temporary fixation of the bone fragments with the KIRSCHNER wire enables a largely minimally invasive procedure on the one hand, and on the other hand precise screw placement via the KIRSCHNER wire.

The cannulated CBS system is modular and designed for different patient sizes: It comprises a basic instrument set and 4 modules (toy breeds / cat, dog small, dog medium and dog large). The individual modules include a selection of screw lengths and the instruments required for the respective implant size, which are required in addition to the basic instrument set.

Titanium Compression Screws

•  Self-drilling & self-tapping
• Cannulated for minimally invasive technique and guided
• insertion
• Minimization of soft tissue irritation through self-cutting
• grooves on the head thread
• Cut back flanks in the head and shaft for easier explanation
• Different diameters (3.0, 4.0, 4.5, 5.5 and 6.5 mm) for a wide
• range of indications
• Screw and thread design enable optimal fixation
• Optimization of the fracture or osteotomy compression

Technical Characteristics

•  Screw material: TiAl6V4
• Easier removal of the implants after the fracture has healed
• Improved fatigue strength of the implants
• Reduction of the risk of inflammation and allergies
• Titanium also reduces artefacts in post-operative imaging
• Biocompatible
• Surface anodized with a uniform, continuous passivation layer
• Colour-coded for easy determination of the size diameter
