title: MR Imaging of the Plantar Plate: Normal Anatomy, Turf Toe, and Other Injuries.
abstract: The metatarsophalangeal (MTP) joint complex is a weight-bearing structure important to the biomechanics of the standing position, walking, shoe wearing, and sport participation. Acute dorsiflexion injury of the first MTP joint, "turf toe," is common among American football and soccer players. The first and lesser MTP joint complexes can be affected by degenerative or inflammatory arthritis, infarct, and infection. These conditions can lead to plantar plate disruption. Imaging studies help physicians to properly diagnose and treat this condition. This article reviews the anatomy, diagnostic imaging, and clinical management of injury and pathology of the first and lesser MTP joint complexes.
