Radiographic Findings

The presence of an os trigonum can be generally confirmed with plain radiographs. Lateral radiographs of the ankle in maximal plantarflexion may demonstrate impingement of the os between the distal tibia and the calcaneus. A bone scan will usually demonstrate intense and localized radionucleotide uptake over the posterior talus if significant injury has occurred

Figure 70-6 A bone scan representing localized radionucleotide uptake in the region of the os trigonum. In the proper clinical setting, this study is consistent with os trigonum syndrome.

A computed tomography study may demonstrate an acute fracture or irregular margins of the os trigonum, thereby suggesting the presence of pathology. In the event that diagnosis remains uncertain, OTS may be confirmed by a positive response to a fluoroscopically guided injection of approximately 0.5 mL of a short-acting anesthetic12 (Fig. 70-7).
