Traumatic facet joint dislocation in Western Australia

Area of Science:

• Orthopedic Surgery
• Trauma Care
• Spinal Cord Injury Research

Background:

• Facet joint dislocation is a severe traumatic injury with significant clinical consequences.
• Western Australia's vast geography presents challenges for timely spinal trauma management.
• Delays in accessing centralized care at Royal Perth Hospital (RPH) are common for rural patients.

Purpose of the Study:

• To investigate the impact of delayed diagnosis and treatment on clinical outcomes for facet joint dislocations.
• To identify potential disparities in outcomes between urban and rural patients with this injury.
• To inform the development of improved management protocols for spinal trauma in remote areas.

Main Methods:

• Retrospective analysis of facet joint dislocations presenting to RPH over a 46-month period.
• Data collection included patient demographics, injury mechanisms, and neurological assessments (American Spinal Injury Association - ASIA scale).
• Comparison of outcomes based on geographical origin (urban vs. rural) and time to reduction.

Main Results:

• A total of 51 patients were analyzed (23 urban, 28 rural).
• Rural patients experienced a higher incidence of poorer neurological outcomes (ASIA C or lower) compared to urban patients.
• Delayed reduction of facet joint dislocations generally correlated with less favorable final ASIA scores.

Conclusions:

• Geographical distance and delayed treatment significantly impact outcomes for facet joint dislocations in Western Australia.
• Centralized spinal trauma services face challenges in mitigating delays for remote populations.
• The findings support the need for optimized management protocols to improve care for patients with spinal trauma in large geographical regions.
