Abstract
A portable bone distraction apparatus comprises a frame having a pair of relatively moveable parts which are respectively connectable to the bone parts on opposite sides of a break and tissue condition sensors positionable on opposite sides of a break. The sensors determine tissue conditions such as temperature or oxygen content. The apparatus includes a microprocessor control circuit which governs rate and frequency of distractions with automatic termination or reduction of the rate and/or frequency of distraction if sensed conditions proximate the break exceed predetermined programmed values.
