Development of the small AO fixator to the current set

An indirect system to reduce and hold comminuted fractures of the distal radius was developed in the mid 1970's starting with a simple threaded distraction rod and advancing to a versatile system of rods and universal clamps. This system has gained wide acceptance since then and is used for the wrist joint and for other indications in surgery of the hand, the upper limb, the foot and in paediatric orthopaedics.
