Description

The Bilok® ST Screw is a cannulated, sterile, single-use bone screw made of an absorbable Poly (L-lactic) acid and calcium phosphate which will gradually be absorbed into the body over a period of 24 months. This function however is patient dependant. The Bilok® ST Screw is for use as a fixation screw in cruciate ligament surgery. It provides a combination of suspension and compression fixation that resorbs and it is subsequently replaced with bone during the healing process. Bilok® ST Screw is biodegradable and biocompatible.
