ActivaScrew™ - Bioabsorbable screw
ActivaScrew™ is an absorbable surgical implant used in fracture treatment, osteotomy, arthrodesis and bone graft surgery.
ActivaScrew’s™ patented Auto-Compression™ technology reduces the risk of unstable fixation. This technology tightens the fracture line and it provides additional support to proper ossification. ActivaScrew™ degrades slowly in the span of approximately two years slowly transferring the stress back to the bone and in doing so accelerating rehabilitation. ActivaScrew™ is fully absorbed in the human body conditions, so there is no need for implant removal operation. This also accelerates the healing process. ActivaScrew™ material is replaced by bone in approximately two years*.
ActivaScrew’s™ benefit lies in the patented Auto-Compression™ technology, which maintains compression during the bone healing. The diameter of the screw will increase, and the length will decrease 1-2% in the human body conditions, locking itself in place and maintaining needed compression for appropriate bone healing. The functionality of the ActivaScrew™ begins during surgery, actively maintaining fixation during and after implantation, which is conducive to proper ossification. ActivaScrew™ is made of PLGA, which biodegrades in the body in approximately two years. ActivaScrew™ offers more freedom for the medical professional in the surgery room. Like all Activa series implants, ActivaScrew™ can be cut for example with hot wire or scissors if needed.
ActivaScrew™ is compatible with AO standard instrumentation.
