Pantalar arthrodesis creates a sensate prosthesis consisting of the ankle and rearfoot complex. Its primary purpose is to create a plantigrade stable rearfoot and ankle. Special attention must be placed on the technical aspects of this procedure, particularly the positioning of the ankle and subtalar complex.
There are many variables that factor into the decision to fixate a metatarsal head osteotomy. These decisions should be based on a thorough understanding of all of these factors. This article discusses osteotomies in a generic sense and the many variables that should be considered. It should be noted that whether internal fixation is employed or not, a thorough understanding of ASIF principles and bone healing is greatly beneficial. Many factors affect stability; these are discussed, as well as subtle changes in various procedures that can dramatically alter stability and therefore the need for fixation.
Transchondral fractures of the talar dome are frequently overlooked on initial and subsequent radiographic examination in the patient with ankle complaints. The etiology, treatment and difficulty in diagnosis of transchondral fractures of the talar dome are discussed.
