Automator Advantages

"... The greater the distraction frequency, the better the outcome..."

Dr. G.A. Ilizarov

The Automator performs precise micro-distractions up to once each minute rather than every six hours as is typical with manual systems. A study performed at Texas Scottish Rite Hospital (Makarov, 1999) demonstrated in a goat model that muscle tissue was preserved far better during automated (more continuous) lengthening than with 1/4mm increment distraction.

The University of Oslo (Steen, 1999) documented forces generated during distraction in a clinical study using patients having bilateral lengthenings. A comparison of Automated-high frequency distraction on one limb to manual distraction on the other limb revealed that continuous distraction substantially reduced the forces generated during lengthening. Furthermore, the Norwegian group noted a correleation between forces generated during distraction and pain experienced by patients. Patients with both legs lengthened felt less pain on limbs lengthened automatically using the Automator.

Main Advantages

  • Adaptable. Easily integrates with circular external fixators with or without outrigging brackets. Ideal for both uniform distraction and angular corrections. Since the device can be mounted regardless of how far apart the ring components are, Automator 2000 is always convenient to install.
  • Safe. Features a self-monitoring, fail-safe system with alarms and manual overrides.
  • Programmable. Rates range from .5 mm to 4.0 mm per day. Rhythm at 1 mm per day is 360 increments per day.
  • Convenient. The durable Automator 2000- adds just 230 grams (8 ounces) per device to the fixation system. Waterproof to promote patient activity.
  • Affordable. Offered to hospitals at similar rates as manual distracters.
  • Fracture Site Stimulation. M1000 Automator may be programmed to compress and distract at the end of a procedure (cyclical loading) to encourage bone consolidation and strength.
  • Patient Preferred. Patients prefer the ease of automatic adjustments and report greater peace of mind and reduced pain.
