Biotrak™ Resorbable Screw

With the Biotrak Headless Resorbable Compression Screw, Acumed Sports Medicine has designed an advanced orthopedic solution for addressing bone applications where a bioresorbable implant material is desired.

Biotrak is a true example of innovation and function combined into one versatile system. The Biotrak incorporates the same advanced technology as the Acutrak family of headless compression screws: variable thread pitch, tapered profi le, cannulation, and a fullythreaded length.

Injection molded from 100% poly L-lactic acid (PLLA), Biotrak screws resorb after the bone is healed. PLLA also reduces the risk of weakening (stress shielding) the bone during the healing process. As a semi-crystalline polymer, PLLA offers increased strength and stiffness compared to amorphous polymers.

Biomechanical tests have proven that the Biotrak is comparable to Acutrak in terms of both compression and pull-out strength.

These features make versatility a hallmark of the Biotrak screw. Biotrak is indicated to provide fi xation of small bone fractures, osteotomies, arthrodeses, cancellous fracture fragments and osteochondral lesions in the upper and lower extremities.

Features

Acutrak® Technology
A patented variable pitch and tapered design allows the Biotrak™ to compress two bone fragments without the need for a head or over drilling the proximal fragment to create compression. The fully-threaded length assists in generating and maintaining compression during cyclic loading.

Radiolucent
Composed of PLLA, the Biotrak Headless Resorbable Compression Screw enhances imaging abilities by reducing interference with imaging techniques; i.e. it is compatible with magnetic resonance imaging and leaves no image on an X-ray.

Minimally Invasive Instrumentation
A unique cannulated, tapered driver/ejector engages the screw along its entire length to maximize contact and drive it effectively into the conically reamed and tapped hole. The driver/ejector allows the surgeon to view the Biotrak’s trajectory and depth under fl uoroscopy. Once inserted, the ejector pushes the screw off the driver in a controlled manner to maintain fragment positioning.
