VENUS Fixation Spinal Fixation System

The VENUS® screw-rod fixation system was developed to stabilise the thoracic and lumber spine. The extensive range of pedicle screws maximises the surgeon’s intraoperative flexibility. It may be used mono-segmentally as well as multi-segmentally. The system stands out due to its high degree of biomechanical stability. It features addon modules such as long-head and augmentable screws, multiple threaded osteoporosis screws (6T screws), hooks, connectors and various types of rod with different degrees of rigidity and a set of minimally invasive tools. The possibility of a free combination of these...

Pedicle screws Standard pedicle screws The unique, self-tapping thread design removes the need for separate cutting outlines. The screw head contains a macrostructure, which lends the system great biomechanical stability. The variety of screws means that all types of bone can be treated. 6T Pedicle screws The main feature of 6T pedicle screws is the thread design of the screw shaft. The thread is divided into a cancellous thread on the lower section and a cortical thread on the upper section of the screw shaft. The two deeper threads on the lower section give a better hold in cancellous bone....

The 6T pedicle screws can be used with both VENUS Standard Instruments and in a minimally invasive way with VENUS®mini. A firm hold is preferred in osteoporotic bones and this is noticeable from the moment each screw is screwed in. The advanced thread profile offers the following advantages over standard systems: • Protects against screws loosening with physical pressure • Increased screw-in speed • Optimal hold in osteoporotic bones Cortical thread Four-ridge fine thread for improved primary stability in the cortical bone and pedicle Cancellous thread Two-ridge thread for improved hold in cancellous...

Implant rods Straight and curved rods in varying lengths, shapes and materials reduce the effort involved in bending and cutting the rods to length during the OP to a minimum. The VENUS® instrument set is among the most outstanding surgical instrument systems. The system is the exclusive product of “Made in Germany” engineering skill in line with ISO and EC specifications. Nitinol phantom rods and special alignment markers on the rods enable the rod to undergo optimum preparation before being inserted into the construction. For particular correctional procedures, the VENUS® system also offers...

Surgical Technique Set the pedicle insertion point. Open the pedicle canal using the Awl. The pedicle canal is awled. Using light pressure, the Pedicle Probe is advanced into the pedicle canal carefully in half rotations. All pedicle screws are self-tapping. However, we recommend using taps in cases where the bone structure is very strong. These are available for all screw diameters. Note: There are two types of Pedicle Probe available: straight and curved. Note: For 6T screws we offer special taps to prepare cancellous and cortical thread. We always recommend using the tap that corresponds to...

Surgical Technique Inserting the pedicle screws I Inserting the pedicle screws II Monoaxial screw: The tip of the Monoaxial Screw Driver clicks into the screw head and secures the screw. The screw is screwed into the pedicle canal. information of the Polyaxial Screw Driver.) Set the rod length. A Phantom Rod is contained in the instruments to make it easier to set the rod length. Polyaxial screw: First, insert the screwdriver tip (inner shaft) into the screw head and attach it to the outer hexagon of the thread shaft. Then connect the outer guide to the screw head by screwing it into the inner...

Adjust and insert the rodUsing the Approximator Insert the rod into the screw heads using the Rod Inserter and, if need be, with the help of your fingertips. The rod profile undergoes fine tuning and the rod is bent to the corresponding radius. If necessary, place the rod using an Rod Pusher or a Rocker to ensure the correct positioning in the screw head. Position the Rocker on the screw head by inserting the fork ends into the lateral grooves of the screw head. Crank the rocker shaft until it is sitting on the rod. Then continue to crank it carefully, making visual and, if need be, x-ray checks...

Surgical Technique Compression / Distraction If required, the Persuader Forceps Style can also be used to reposition the moved spine or to position the rod in the screw head. Once the rod is correctly positioned in the screw head, fix the rod in the screw head with the set screw using the Set Screw Inserter. To prevent cross-threading while screwing in the set screw, first screw in a counterclockwise direction until you clearly feel the thread “click into” the screw head. Then continue to screw in the set screw. Position the Compressor or Distractor on the screw heads and carry out the compression...

Transverse Connector Final tightening Final construction Attach a Transverse Connector Hook with the help of the Transverse Connector Inserter. Connect the second hook with the Transverse Connector Rod which is inserted via the Transverse Connector Rod Holder and attach it to the second rod of the construction. Align the elements and connect the Transverse Connector Hooks using the Transverse Connector Rod. The Counter Holder is guided over the screw head and pushed all the way onto the rod. Ensure that the notches at the distal end of the Counter Holder take up the inserted rod. Couple the Set...
