Vertical Wire Forefoot Fixation: An Advanced Technique for the Dynamic External Fixation Apparatus.

Abstract

External fixation is used for the correction of select foot and ankle deformities. We have found the traditional forefoot crossing wire technique to be insufficient in terms of both individual metatarsal control and forefoot manipulation when using a dynamic ring fixator to correct forefoot deformities. We developed a forefoot fixation technique at the University of Cincinnati Medical Center, using 5 vertical wires to gain greater forefoot control while performing more precise skeletal manipulation for multiplanar deformity correction. The associated risks of infection, neurovascular injury, and other soft-tissue injury should be further investigated. This proposed vertical wire construct is an advanced method with which the foot and ankle surgeon can correct complex lower limb deformities.
