Benefits

Screw design

sysorb® screw has been designed with four features: Turbine tulip-like drive; hollow perforated lateral; incremental screw body; blunt thread.

  • Turbine tulip-like drive can enhance torque of the interference screw which is conducive to insert the screw.
  • Hollow perforated lateral allows easy ingrowth of bone tissue, which facilitates healing the tendon bone after tendon implant.
  • The fixation strength increases gradually in gradient during insertion of the screw into the bone tunnel, which ensures the fixation of the graft.
  • The blunt thread prevents injury to the graft during screw implanting.

Material

sysorb® interference screw is made by blending absorbable polylactic acid-hydroxyacetic acid (PLGA) + β-tricalcium phosphate (β-TCP) material.

  • Absorbable PLGA can be degraded in human body, and there is no need to remove it after recovery, and no foreign object remains in the human body.
  • β-TCP material is a kind of bone replacement material, which shows excellent biodegradability, biocompatibility and bone inducibility. Its degradation products are alkaline which can neutralize the acidic products producing during  PLAG degradation.
