Cannulated Headless Compression Screw

Cannulated Screw System is intended for fixation of fractures, fusions, and osteotomies of large and small bones and consists of screws and washers.

The main advantage of cannulated screws is that they can be inserted over a guide wire or guide pin. The diameter of the guide pin is much smaller than the cannulated screw and can be more accurately placed using fluoroscopy in the operating room. In addition, given its small diameter, the guide pin can be reinserted several times if necessary for accurate placement without excessive damage to bone.

With diameters ranging from ø2.4 to ø7.3, cannulated screws cover a wide range of indications and add comfort to the surgeon with different thread lengths that allow him to choose the appropriate lag screw for the given fracture.

All screws are cannulated for use over a guide wire. Each screw is partially or completely threaded using a cancellous tooth form. Cannulated bone screws are commonly used in the pelvis, hip, knee, ankle, and foot. Femoral neck fractures, sacroiliac joint disruptions, tibial plateau and femoral intercondylar fractures, calcaneal fractures, talar fractures, ankle arthrodesis, subtalar arthrodesis, fracture of the distal femur, and humeral, olecranon application.

Screws are cannulated in order to be used over a guide wire and each screw is either partially or fully threaded using a cancellous thread form. Cannulation is intended for minimally invasive percutaneous insertion. Partially threaded screws may be used to lag one bone fragment to another, where the far bone fragment is captured by the threads of the screw and pulled toward the near cortex fragment on the head side of the screw. Fully threaded screws are intended to be used to stabilize fractures with little to no compression across the fracture.

The increasing cost of healthcare and accompanying payment systems leads to low cost options such as cannulated screws. In non-displaced fractures, screws can provide clinical results equal to higher cost options.

It is designed to reduce soft tissue irritation compared to standard screw heads.

The Self-Tapping screw bit is designed to facilitate the insertion of the screw and may eliminate the need for tapping in some cases.
