technetium-tc-99m-medronate and Sprains-and-Strains

Ankle sprains are a common injury and may occur in as many as 75% of sporting participants. More complex injuries involving a rotational component may lead to injury of the interosseous membrane, its supporting ligaments, or the tibial plafond, compromising the integrity of the ankle mortice. Four such cases that show the scintigraphic manifestation of the injury are presented. In addition to the standard planar views of the ankles, special magnified anterior views were obtained with the feet in internal rotation of 25 degrees to 35 degrees. These special views facilitated the diagnoses.

Three-phase bone scintigraphy diagnosis of Lisfranc injury in a patient after foot trauma is discussed. Early diagnosis of Lisfranc joint injury is frequently missed and radionuclide bone scintigraphy may show a specific pattern where the x-rays are inconclusive.

In a retrospective study, patients with suspected scaphoid fracture had an average of three sets of scaphoid radiographs prior to scintigraphy. Scans were performed an average of 3 months after injury and many were inconclusive because of disuse changes. A prospective analysis of early scintigraphy in 35 cases over 18 months was carried out. Scans were performed at an average of 15.5 days after injury in selected cases. Patients had an average of 1.28 sets of negative radiographs prior to scanning. There were no false negative scans and in 13 with focal uptake a wrist fracture was demonstrated. Diffuse uptake was thought to be indicative of ligamentous damage or reflex sympathetic dystrophy. Early scintigraphy was found to be a sensitive, reliable and cost-effective examination in cases of suspected significant wrist injury.
