Review squeeze test.

Provided that there are no fractures of the tibial or fibular shafts, if ankle pain can be elicited by this squeeze maneuver, one should suspect an injury to one or more of the components of the tibiofibular syndesmosis.

Questions:

  • What are some clinical criteria that would warrant a radiographic examination of an injured ankle?

  • What are the 3 standard radiographic views that are obtained on patients with ankle injuries?

  • When do the distal tibial and distal fibular epiphyses appear, and by what age do these epiphyses fuse to the adjacent metaphyses?

Discussion & Teaching Points

It is estimated that over $500 million dollars are spent each year on ankle radiographs. However the majority (up to 85%) of these radiographs are negative. In 1992, a Canadian study suggested the adaptation of the Ottawa ankle rules, which could be used to order ankle radiographs based on selected clinical criteria. It is important to remember that this study excluded patients younger than 18 years of age. Therefore, since the Ottawa study did not include growth plate injuries, one should not strictly adhere to these rules when deciding whether or not to obtain a radiograph on a pediatric patient. Based on these Ottawa ankle rules, clinical indications that would warrant a radiographic evaluation would include any one of the following criteria:

  • Inability to bear weight both immediately after the injury and in the Emergency Department.

  • Bony tenderness over the posterior edge, tip or distal 6 cm of the lateral malleolus.

  • Bony tenderness over the posterior edge, tip or distal 6 cm of the medial malleolus.

  • Tenderness over the base of the 5th metatarsal.

A complete, standard radiograph examination of the ankle should include 3 views (AP, lateral, and a mortise view).
