Summary

Simple traumatic hip dislocations lead to excellent long-term outcomes. Complex dislocations and intra-articular fragments, however, are linked to poorer results and osteoarthritis, suggesting surgical intervention may be beneficial.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Radiology

Background:

  • Traumatic hip dislocations can lead to severe long-term complications, including osteoarthritis and osteonecrosis.
  • Identifying prognostic factors is crucial for managing hip dislocations and improving patient outcomes.

Purpose of the Study:

  • To determine variables and prognostic factors influencing clinical and radiological outcomes of traumatic hip dislocations.
  • To evaluate long-term results following hip dislocation treatment.

Main Methods:

  • Retrospective review of hip dislocations and fracture-dislocations from 1999-2012.
  • Computed tomography (CT) scans performed post-reduction.
  • Clinical evaluation using Harris Hip Score and Merle-d'Aubigné-Postel method; radiological assessment via Thompson and Epstein classification.

Main Results:

  • 30 cases (29 patients) with a mean 11-year follow-up.
  • Simple dislocations (70%) showed excellent outcomes with no osteoarthritis.
  • Complex dislocations (30%) and intra-articular fragments were associated with higher rates of osteoarthritis (13.3%) and avascular necrosis (10%).

Conclusions:

  • Complex hip dislocations are linked to inferior functional and radiological outcomes compared to simple dislocations.
  • Intra-articular fragments show a strong association with osteoarthritis development, supporting surgical removal.
