Different faces of the triple arthrodesis.
Patients with severe pes planovalgus or cavovarus foot deformities who fail conservative treatment may require a triple arthrodesis. Modifying the triple arthrodesis to include extended bone wedge resections allows for improved correction. The goal of each procedure is to obtain a less painful, plantigrade foot, and to improve function. Additional hindfoot or midfoot osteotomies may be needed in the modified triple arthrodesis. Midfoot or forefoot cavus can be addressed with either the Japas, Cole, or Jahss osteotomies, as described above. Residual hindfoot valgus can be adequately corrected with a medial displacement osteotomy of the calcaneus. Residual hindfoot varus is preferably corrected through a lateral closing wedge calcaneal osteotomy. This allows for adequate correction without the need for bone graft or an extended medial incision in the area of the tibial neurovascular bundle. Good results have been obtained with these types of complicated reconstructive procedures.
