title: Computed tomography (CT) of fractures of the ankle and foot: correlating fracture patterns with the presence of tenosynovial fat: Tenosynovial fat in ankle and foot fractures.
abstract: OBJECTIVE
  To correlate ankle and foot fracture patterns with the presence of tenosynovial fat on computed tomography (CT).
  
  
  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.
