Correction of complex foot deformities using the V-osteotomy and the Ilizarov technique.

Complex foot deformity is a multiplanar deformity with or without foot shortening. It also includes deformed feet with poor soft-tissue coverage, relapsed or neglected cases, and those with acompanying problems such as leg-length discrepancy, lower leg deformity, osteomyelitis and nonunions. Traditionally, correction of these deformities can be achieved by extensive soft tissue releases, osteotomies or arthrodesis with or without internal fixation. This usually involves excision of large appropriate bony wedges and has many disadvantages, including neurovascular injury, soft tissue problems and a shortened foot. We present our experience with a group of severe deformities of the foot that we managed using the V-osteotomy combined with the Ilizarov technique. We present our algorithm of management of complex foot and ankle deformities, together with our prerequisites for patient selection. A detailed description of the operative technique, postoperative care and possible complications is also presented. The combination of the Ilizarov technique and the V-osteotomy offers versatility in foot deformity correction, enabling correction of individual components of the deformity at rates that may be tailored to achieve accurate three-dimensional control.
