Patients transferred with a dislocated hip face a higher risk of sciatic nerve injury. Prompt hip reduction at the initial facility can mitigate this risk, reducing nerve damage incidence.

Area of Science:

  • Orthopedic Surgery
  • Neurology
  • Trauma Care

Background:

  • Hip dislocation is a significant orthopedic emergency.
  • Delayed treatment of hip dislocation can lead to complications.
  • Sciatic nerve injury is a potential complication of hip dislocation.

Purpose of the Study:

  • To investigate the association between hospital transfer and sciatic nerve injury in dislocated hips.
  • To determine if delayed hip reduction increases the risk of nerve damage.
  • To evaluate the impact of time to relocation on sciatic nerve injury outcomes.

Main Methods:

  • Retrospective study of 106 dislocated hips over 12 years.
  • Comparison of sciatic nerve injury rates between hips reduced at the first facility and those transferred with dislocation.

  • Analysis of time to hip relocation and its correlation with nerve injury severity.

    • Main Results:

    • Patients transferred with a dislocated hip had a significantly higher incidence of major sciatic nerve injury (P =.0453).
    • Longer time to hip relocation was associated with a greater risk of major motor nerve injury (P =.016).
    • Associated fractures did not influence sciatic nerve injury rates.

    Conclusions:

    • Delayed hip reduction, particularly following inter-facility transfer, increases the risk of sciatic nerve injury.
    • Prompt management of hip dislocations is crucial to prevent neurological deficits.
    • The duration of hip dislocation is a critical factor in the incidence and severity of sciatic nerve injury.
