Intertrochanteric Hip Fracture IMHS Pre-op Planning

  • Smith & Nephew Trigen Intertan (provides solid fixation in the head, more time consuming)
  • Stryker Gamma Nail (less fixation in the head, less time consuming)
  • Biomet Peritrochanteric Nail (PTN)
  • Consider subfascial transexamic acid injection to reduce peri-operative transfusion requirements by 43%.  (Drakos  A, JOT 2016, 30:409)
  • Fluoro tips: AP image with machine approximately 15-20° over the top of the patient generally demonstrates the outline of the greater trochanter, and aids in visualization of the starting point for the nail.  Lateral view is generally best with rotation set around 65 degrees.  

Intertrochanteric Hip Fracture IMHS Technique

  • Sign operative site.
  • Pre-operative antibiotics, +/- regional block.
  • General endotracheal anesthesia
  • position. All bony prominences well padded.
  • Examination under anesthesia.
  • Prep and drape in standard sterile fashion.
  • Irrigate.
  • Close in layers.

Intertrochanteric Hip Fracture IMHS Complications

  • Screw cut-out: associated with tip-apex distance >25mm, increasing age of the patient, an unstable fracture, a poor reduction, & use of a high-angle (150deg) side-plate
  • Loss of fixation
  • Osteonecrosis of the femoral head
  • Femoral shaft fracture
  • Nonuion
  • Infection
  • Nerve or vascular injury
  • Painful hardware
  • Compartment Syndrome
  • CRPS
  • DVT / PE
  • Heterotopic Ossification
  • Infection, nerve or artery damage, stiffness, weakness, incomplete relief of pain, incomplete return of function or motion, incomplete return to sport, need for further surgery. Medical complications including heart attack, stroke, blood clots, pulmonary embolus, transfusion reaction or death.
