Noncontiguous unstable spine fractures.

Area of Science:

• Orthopedics
• Neurosurgery
• Trauma Surgery

Background:

• Noncontiguous spine fractures are rare, occurring in 1.6-16.7% of spinal fractures.
• Previous studies often included stable fractures, necessitating a focus on unstable fractures requiring intervention.
• Unstable noncontiguous spine fractures are challenging to diagnose and treat, often resulting from high-impact trauma.

Purpose of the Study:

• To evaluate the diagnostic delay and clinical/radiologic outcomes of noncontiguous unstable spine fractures.
• To identify factors contributing to delayed diagnosis and their impact on patient outcomes.
• To compare the effectiveness of surgical versus conservative management for these fractures.

Main Methods:

• Retrospective review of 1054 spinal fracture patients over 14 years.
• Detailed analysis of 39 patients (3.7%) with noncontiguous unstable spine fractures.
• Inclusion of clinical investigation for 39 patients and chart review for 1054 patients and 100 roentgenograms.

Main Results:

• Delayed diagnosis of secondary fractures occurred in 23.1% of patients but did not lead to neurological deterioration.
• 32 extraspinal injuries were identified, with 14 requiring surgical intervention.
• Surgical treatment resulted in earlier mobilization and less kyphotic deformity, while conservative treatment led to increasing deformity.

Conclusions:

• Delayed diagnosis of noncontiguous unstable spine fractures often has no adverse clinical consequences.
• Both conservative and operative treatments can lead to neurologic improvement.
• Surgical intervention is associated with superior outcomes regarding mobilization and spinal deformity.
