Avoid ordering MRI in patients with suspected acute Achilles tendon ruptures.
|Rationale and Comments:||MRI is expensive and can lead to treatment delays. History and physical exam findings can establish the diagnosis of acute Achilles tendon ruptures in nearly all instances. Physicians should reserve MRI for atypical presentations and subacute or neglected ruptures when preoperative planning is needed. When physicians prefer to use the rupture gap (i.e., apposition of tendon ends) as criteria for management (surgery versus conservative treatment), dynamic ultrasound can be easily substituted.|
