Weight Bearing CT Imaging for Sports Medicine

Common Indications

Syndesmosis

syndesmosis
  • Provide increased sensitivity and specificity over radiographs1.
  • Differentiate pathology from natural variability in patient anatomy via contralateral comparison to uninjured ankle as internal control2.
  • Help detect subtle syndesmosis injuries1.

Lisfranc Injuries

Lisfranc
  • Better characterize bony injuries3.
  • Evaluate the 3D Lisfranc joint complex under physiologic load4.
  • Identify subtle Lisfranc injuries by effectively differentiating between stable and unstable Lisfranc injuries5.

Fractures

Fractures
  • CBCT helps in the evaluation of the fracture healing process which X-Ray can over or under-estimate6.
