ORTHOSORB(R)(1) RESORPTION EVALUATION USING MRI AND HISTOLOGIC ANALYSIS

Resorbable bone fixation devices may be used in various surgical proce dures for internal fixation in place of traditional metallic devices. Currently, there is no radiographic technique for tracing the postsurg ical location and resorption of these devices. This study was undertak en to ascertain whether magnetic resonance imaging is a suitable tool for performing such evaluations. Using an animal model, the authors in vestigated the correlation over time between the magnetic resonance im age of a surgically implanted pin and its histologically verified loca tion and state.
