Femoral Neck Fractures
Updated: Oct 9 2017

Femoral Neck Fracture Closed Reduction and Percutaneous Pinning

Preoperative Patient Care
Operative Techniques
E

Preoperative Plan

1

Template intramedullary nail and cephalomedullary screws

  • measure length of the hip screws

2

Surgical walkthrough

  • resident can describe key steps of the operation verbally to attending prior to beginning of case.
  • list potential complications and steps to avoid them
F

Room Preparation

1

Surgical instrumentation

  • cannulated screws

2

Room setup and equipment

  • radiolucent fracture table (Jackson fracture)
  • c-arm fluoroscopy

3

Patient positioning

  • make sure patient has Foley urinary catheter in place
  • patient supine with feet padded with webril and placed firmly in fracture table boots if contralateral leg dropped down, if raising contralateral leg up 90° use thigh holder
  • padded post deep into groin, move genitals and Foley catheter out of the way
  • ipsilateral arm on stack of blankets over chest and taped down, contralateral arm on arm board
  • prep and drape entire leg up to iliac crest to make sure adequate working area
  • c-arm from contralateral side at 45° towards hip
  • take initial fluoro AP/Lat of hip to examine femoral neck
  • mark position of C-arm to ensure proper positioning during remainder of case (~15° tilt for correct AP xray of hip)
G

Closed Reduction

1

Perform a closed reduction

  • apply gentle traction and internal rotation under fluoroscopic control

2

Verify the reduction is anatomic

  • reduction is considered anatomic when the normal contours of the femoral neck have been re-established in both the AP and lateral views, the normal neck-shaft angle and neck length are restored
  • the relative heights of the femoral head and trochanter should be symmetrical to the contralateral side and no gaps are seen in the fracture
H

Guidewire Placement

1

Position the guidewires

  • these should be in line with the femoral neck axis through poke holes
  • the standard placement is 3 pins in an inverted triangle position

2

Place guidepins

  • place guidepins through stab incisions
I

Screw Placement

1

Place screws

  • place cannulated screws over the guidepins
  • the pin must lie along the axis of the femoral neck in both the AP and lateral views and parallel to the anteversion pin
  • place the screws peripherally in the femoral neck with good cortical butrress
  • espescially in the inferior and posterior neck
  • avoid points below the lesser trochanter due to risk of subtrochanteric fracture postoperatively

2

Verify position of screws

  • verify the position in two planes by fluoroscopy

3

Drill screws

  • spread the soft tissues down to bone
  • place self drilling, self tapping cannulated screws by power over the guidewires
  • use washers in more proximal, metaphyseal locations

4

Confirm the length of the screws is appropriate

  • the screws should be long enough so that all screw threads are on the proximal (head) side of the fracture
J

Wound Closure

1

Irrigation and hemostasis

  • copiously irrigate the wounds

2

Close the skin

  • subcutaneous and skin closure with 2-0 vicryl and staples
