title: Tibiocalcaneal arthrodesis in the high-risk foot.
abstract: The present case series outlines the history and surgical treatment of 6 patients who underwent tibiocalcaneal arthrodesis from April 2002 to May 2012, all with external fixation as the primary or secondary fixation. Surgical intervention was performed by the same surgeon at the same facility. The indication for surgery was a nonbraceable Charcot deformity in 5 (83.3%) patients and bone and soft tissue infection complicating previous intramedullary hindfoot fusion in 1 (16.7%) patient. Talectomy was performed in 2 (33.3%) patients secondary to widespread osteomyelitis of the talus and in 4 (66.7%) patients secondary to avascular necrosis and/or disintegration and fragmentation of the remaining talus. The postoperative complications have been discussed in detail and their management outlined. At the most recent follow-up visit, all patients were independently ambulating on a braceable limb with or without the use of an assistive device. In conclusion, tibiocalcaneal arthrodesis is a reasonable option for limb salvage to produce community ambulators in the high-risk population. We emphasize that although multiple fixation options are available for tibiocalcaneal arthrodesis, a combination of internal and external fixation is vital to its success.
