title: [Initial modifications of the ring fixator apparatus].
abstract: To increase the practicability of Ilisarov's ring fixation apparatus, we introduced the following modifications: Clamping of the fixation wires using a quick collet with a force indicator, which enables reproducibly preuse and rapid clamping. Hardened screws to maintain the tension longer. Production of the olive wire from homogeneous implant steel by the cold-press method. Optimization of the cutting edge at the wire tip. Measurement of tension in the fixation wire. A distractor incorporating a clock and a device showing the distraction achieved so that doctor and patient can better supervise the distraction procedure. Simplifications of the wound dressing.
