Summary

Lumbosacral dislocations are rare but increasing high-energy injuries. Surgical stabilization offers better outcomes than nonoperative care for these complex spinal traumas.

Area of Science:

  • Orthopedics
  • Trauma Surgery
  • Spinal Surgery

Background:

  • Lumbosacral dislocations are infrequent, high-energy spinal injuries.
  • Advances in trauma care may lead to an increase in these cases.
  • This study reviews institutional experience with six lumbosacral dislocation cases.

Observation:

  • Two cases treated nonoperatively experienced significant deformity and pain, necessitating later reconstruction.
  • Surgical management involved decompression, reduction, and posterior pedicle screw fixation.
  • One case required revision with anterior column reconstruction due to implant failure.

Findings:

  • Surgical stabilization achieved a stable lumbosacral junction in most cases.
  • Nerve root injuries demonstrated recovery.

  • Pre-existing conditions like spondylolysis/spondylolisthesis were noted in two patients.
  • Satisfactory clinical outcomes were associated with the absence of pre-existing chronic low back pain.
  • Implications:

    • Surgical intervention is generally superior to nonoperative management for lumbosacral dislocations.
    • Posterior instrumentation is effective, but anterior reconstruction may be needed for complex cases.
    • Patient's pre-existing spinal health significantly influences functional recovery after trauma.
