Intraoperative assessment of fracture reduction

Length, alignment, and rotation should be checked clinically. The knee is taken through a full gentle range of motion to ensure appropriate fracture fixation. Fracture reduction and fracture fixation are then assessed using AP, lateral, and oblique x-rays. Specific questions to be answered in this assessment include:

  • Is there any sagittal plane deformity?
  • How satisfactory is the valgus/varus alignment?

The cable method is recommended for checking the alignment of the limb.

  1. Length, alignment, and rotation should also be checked clinically.
  2. How satisfactory is the placement of the LISS fixator on the midlateral aspect of the tibia?
  3. How satisfactory is the placement of the LISS fixator on the lateral aspect of the tibial condyle.
  4. If in doubt, take an AP and lateral X-ray from the knee to the ankle.
