Abstract
The goal of this study was to compare the capabilities of conventional radiography, CT, and MR imaging in revealing ligamentous and bony changes in patients after hyperflexion injuries.Forty-nine patients with hyperflexion injuries of the foot were included in our study. Conventional radiography, weight-bearing radiography, CT, and MR imaging were performed. All images were reviewed with respect to ligamentous and bony abnormalities and alignment alterations. Eleven patients with joint malalignment underwent surgery, which is considered the gold standard in these patients. Five patients with joint malalignment refused surgery.For all 49 patients, conventional radiographs revealed 33 metatarsal and 20 tarsal fractures. Eight patients presented with tarsometatarsal joint (Lisfranc's joint) malalignment. Weight-bearing radiographs showed joint malalignment in the same eight patients only. CT showed 41 tarsal fractures and 53 metatarsal fractures. Joint malalignment was evident in 16 patients. MR imaging reve...Keywords
