Transcervical shear fractures of the femoral neck

 
 
 
 
 

In young patients, the femoral head should be preserved and fixed internally. In elderly patients with osteoporosis and/or preexisting hip arthritis, arthroplasty is more commonly chosen.

These fractures are more vertical and often can not provide a fulcrum for stable screw fixation, so there would be a high risk of secondary displacement.

Reduction should begin closed and may be extended with percutaneous fragment manipulation. If this still does not provide satisfactory reduction, open reduction is mandatory.

In elderly patients, these fractures have a high risk of failed fixation, nonunion, and avascular necrosis. For appropriately selected patients, arthroplasty may be more successful. This would reduce the need for reoperation and allows early weight bearing. It is, however, a bigger operation with possible serious complications.

Elderly patients will not mobilize easily with restricted weight bearing. Therefore, procedures allowing for immediate weight bearing as tolerated with walking aids should be selected whenever possible.

Fracture management with minimal resources

Main indications

 
 
 

Implants not available, missing infrastructure for surgical intervention, first aid

Disadvantages

  • High risk of nonunion
  • Delayed mobilization and rehabilitation
  • Increased risk of deformity and weakness

Sliding hip screw with antirotation screw

Main indications

 
 
 

Pauwels type II + III fracture, good bone quality

Further indication

  • Physiologically younger patients

Contraindication

  • Significantly unstable fractures

Advantages

  • Minimal soft-tissue exposure and blood loss
  • Straight forward procedure

Disadvantages

  • Requires a supplementary screw for rotational stability
  • Prominent implant may be painful
  • Risk of avascular necrosis
  • Risk of nonunion (10%)

Pauwels type II + III fracture, good bone quality

Further indication

  • Physiologically younger patients

Contraindication

  • Significantly unstable fractures

Advantages

  • Minimal soft-tissue exposure and blood loss
  • Straight forward procedure

Disadvantages

  • Requires a supplementary screw for rotational stability
  • Prominent implant may be painful
  • Risk of avascular necrosis
  • Risk of nonunion (10%)

Femoral neck system

Main indications

 
 
 

Pauwels type II + III fracture, good bone quality

Further indication

  • Narrow femoral neck

Contraindication

  • Extremely high-risk patient (significant comorbidities)

Advantages

  • Reduced risk of secondary displacement (0–13%)
  • Angular stable implant
  • Higher resistance to varus collapse compared to cancellous screw fixation
  • Controlled impaction without lateral protrusion

Disadvantage

  • Risk of surgical complications, including subtrochanteric fracture through screw hole
