title: Dennyson-Fulford subtalar arthrodesis.
abstract: Forty-six patients who had undergone Dennyson-Fulford subtalar arthrodesis for hindfoot valgus deformities secondary to various pathologies were reviewed both radiographically and clinically. Mean age at surgery was 7.67 years; mean follow-up was 5.67 years. Evaluation showed 70% good, 20% fair, and 10% poor results. Pseudarthrosis rate was 6.4%, and was not necessarily related to undercorrection or progressive deformity. Screw sclerosis, which is common, is associated with pseudarthrosis, but not with hardware failure. Hardware problems can be anticipated with intraoperative radiographs, and penetration of the lateral calcaneal cortex up to 1.0 cm is well tolerated.
