Lateral Entry Trochanteric Intramedullary Nailing of Femur

Lateral Entry Trochanteric Intramedullary Nailing of Femur

Michael Glotzbecker, MD

Patient Positioning

  • Supine on the radiolucent fracture table with legs scissored.

    • Bump underneath ipsilateral buttocks to prevent patient external rotation

    • Leg/body in adduction to allow easier access to the lateral hip with hip positioned as lateral as possible on the table

    • Contralateral leg lower to aid in radiographic lateral imaging

    • Ipsilateral arm across chest over pillow to clear operative side

    • Avoid malrotation by placing the hip and the knee cap to the ceiling. Look longitudinally from the foot and the limb position of the anterior hip and anterior knee should match and make sense. Significant internal or external rotation of the foot and the distal fracture should be a cause of concern and reevaluation.

  • Complete fluoroscopic AP and lateral views at the hip, fracture, and knee to assure ability to visualize femur completely and obtain provisional reduction (Figure 21-36A and B).

  • Lateral on the radiolucent fracture table

    • Helpful for larger patients

    • Historically helpful for piriformis nailing. Lateral entry nails make starting point simple for supine nailing

      Figure 21-36 ▪ A and B, Fluoroscopic views confirming adequate visualization for starting point of guide wires.

  • Supine on the radiolucent table

    • Bump underneath ipsilateral buttocks and flank with prep extending to the level of lilac crest

    • Longitudinal traction maintained by assistant

    • Technically more difficult to maintain traction/rotation

Surgical Approaches

  • Surgical exposure is minimal and may be done through a 3 cm incision.

  • Incision marked out under fluoro, taking care to center incision just proximal and posterior as the direction of reaming and nail placement will be from cephalad to the caudally directed entry point

  • Skin incision, followed by fascial longitudinal split and muscle split in line with gluteal fibers down to just lateral to trochanteric tip.
