Mono-Axial Screw

Monoaxial Screw is specifically intended to provide internal fixation to stabilise and immobilise the spine. The screw is put into the vertebrae to encourage fusion, which is the process of connecting two or more vertebrae to form a solid bone mass

Poly-Axial Screw

A polyaxial screw is used to secure orthopedic appliances to bone, particularly the spine. The polyaxial screw has a shaft including a helical screw thread for securing the screw to bone. One end of the shaft has a reverse tapered head tapering toward and away from the shaft from an enlarged median. A spherical shaped swivel, having an opening smaller than the median, is snapped over the head to rotatably engage the shaft. A connector with a dome shaped cavity on one end and bifurcated tabs on the other is connected with the swivel and tightened in place with a set screw and guide ring. An appliance is held between the bifurcated tabs. The tabs are frangible to reduce the profile above the appliance.

Reduction Poly-Axial Screw

Poly-Axial pedicle screws with extended tabs, enabling rod reduction without the use of reduction instruments. The tabs can be broken off after rod reduction. The screw heads allow for a polyaxial adjustment of 90 around 360

Fenestrated Pedicle Screw

Fenestrated pedicle screws permit augmented fixation via injection of bone cement into the vertebral body upon screw placement, potentially mitigating the difficulties in achieving adequate stabilization in the patients
