Distal Femur Extraarticular fracture, wedge

Closed reduction internal fixation (CRIF); less invasive stabilization system (LISS)

MIO - less invasive stabilization system (LISS)

Indication summary: Displaced reducible fracture, Surgeon's preference

Skill: Highly experienced and skilled surgeon
Equipment: Full specialized surgical and imaging resources

DCS vs. Condylar LCP vs. LISS

No evidence exists proving the superiority of the use of either the DCS, the Condylar LCP or the LISS with such fractures.

Indications

  • Closed fractures where a closed reduction is possible
  • Some periprosthetic fractures

Contraindications

  • Polytrauma patient in unstable condition
  • Medically unfit for surgery
  • Image intensifier unavailable
  • Early pregnancy (up to 12 weeks gestation; risks of intraoperative ionizing radiation)
  • Local soft-tissue compromise

Advantages

  • Fracture reduction
  • Less invasive procedure
  • Minimizes secondary soft-tissue damage 
  • High union rates
  • Definitive procedure
  • Fracture stabilization allows early patient mobilization
  • Can be used in cases of pulmonary compromise
  • Less visible scarring

Disadvantages

  • Closed reduction is more challenging than open reduction
  • Difficult control of distal femoral fracture fragment
  • Higher rate of malreduction
  • Technically demanding procedure
  • Frequent use of image intensifier – risk of increased exposure to ionizing radiation
  • Risk of infection
  • Risk of implant related complications
