ActivaScrew™ Cannulated

Product Overview


Bioretec’s ActivaScrew™ Cannulated offers a broad range of fully threaded and partially threaded cannulated screws for fixation of fractures and osteotomies.

Implants have been used worldwide and the track record is excellent (in US MAUDE database no records). The occurrence of potential complications is less than 0.01%.


Benefits of using ActivaScrew™ Cannulated

Auto-Compression™ to reduce the risk of unstable fixation. Auto-Compression™ tightens the screw lengthwise contraction of the screw.
Due to Auto-Compression™ Bioretec ActivaScrew™ Cannulated has ability to maintain compression during the bone healing.

The functionality of the ActivaScrew™ Cannulated begins during surgery, actively maintaining fixation during and after implantation, which is conducive to proper ossification.

Auto-Compression™ is caused by dimensional changes in hydrolytic conditions. Diameter of the screw will increase and length of the screw will decreased 1 - 2% compared to the initial dimensions.

Material properties

ActivaScrew™ Cannulated gives an excellent fixation enabling bone to maintain its own strength.

ActivaScrew™ Cannulated is made of PLGA** and biodegrades in the body safely and in a controlled manner within approximately two years.

** PLGA - poly(lactic-co-glycolic acid), optimal combination with a long history of safe medical use and the degradation by hydrolysis into alpha-hydroxy acids that are metabolized by the body. 

ActivaScrew™ Cannulated is FDA cleared and CE approved.


Bioretec ActivaScrew™ Cannulated: high strength and stiffness facilitate stable fixation.
