title: Stress fractures and tibial cortical hypertrophy after tibiotalocalcaneal arthrodesis with an intramedullary nail.
abstract: Twelve patients underwent successful tibiotalocalcaneal arthrodesis using a locked intramedullary nail with posterior moldable bone grafting. Two of the patients developed a nondisplaced stress fracture around the proximal interlocking screws, which responded to immobilization at 8 and 15 months after surgery. In 7 of 12 patients, > or =2 mm of cortical hypertrophy was noted between the proximal interlocking screws along the medial and/or lateral aspect of the tibia. Although intramedullary nailing can achieve satisfactory tibiotalocalcaneal arthrodesis, the stress risers in the tibial diaphyses do result in a stress reaction in a significant number of patients.
