Abstract
PURPOSE: To correlate ankle and foot fracture patterns with the presence of tenosynovial fat on computed tomography (CT). MATERIALS AND METHODS: In this retrospective, cross-sectional, observation study, two blinded musculoskeletal radiologists independently reviewed 89 CT scans of patients with ankle or foot fractures and recorded the presence of fat about Henry's knot, tibialis posterior tendon, and peroneus longus tendon. RESULTS: The agreement between the two readers ranged from excellent to substantial. Sixteen to 23 percent of fractures were associated with tenosynovial fat. CONCLUSIONS: The finding of tenosynovial fat following ankle or foot trauma warrants a closer search for a fracture.
