Sacroiliac luxation

Contributor(s): Andrew Gardiner, Rosanna Marsella, J Yovich

Introduction

  • Cause: the normal articulation between the sacrum and ilial wing is disrupted as a result of trauma, eg hit by car (HBC).
  • Unilateral or bilateral luxation may be present.
  • The condition is usually seen in association with pelvic fracture, and two or more additional sites of fracture are normally observed at the pubis or ischium.
  • Signs: lameness on affected limb.
  • The lumbosacral nerve trunk is in proximity to this area and may be damaged.
  • Diagnosis: history, signs, radiography.
  • Treatment: conservative (minimal luxation) or surgical
    • Severe displacement.
    • Marked instability.
    • Pelvic narrowing.
    • Severe pain.
    • Deficits attributable to lumbosacral trunk present.
  • Prognosis: generally good.

Pathogenesis

Etiology

  • Trauma.

Predisposing factors

General

  • Intact male cats due to roaming tendencies.

Pathophysiology

  • Traumatic incident sufficient to cause fracture/dislocation of the sacroiliac joint and associated pelvic fractures.
  • The box nature of the bony pelvis means that multiple fractures are usual in association with sacroiliac luxation.

Timecourse

  • Acute (HBC).
