Nonoperatively treated type A spinal fractures: mid-term versus long-term functional outcome

Area of Science:

• Orthopedics
• Spinal Surgery
• Traumatology

Background:

• Type A spinal fractures are common vertebral injuries.
• Nonoperative management is frequently employed for these fractures, particularly in neurologically intact patients.
• Long-term functional outcomes of this treatment approach require further elucidation.

Purpose of the Study:

• To evaluate the mid-term (4 years) and long-term (10 years) functional outcomes of patients with type A spinal fractures treated nonoperatively.
• To assess the stability of functional outcomes over time in this patient cohort.
• To identify any factors influencing long-term functional results.

Main Methods:

• A cohort of 50 patients with type A spinal fractures and no neurological deficit were treated nonoperatively.
• Functional outcomes were assessed using the Visual Analogue Scale Spine Score (VAS) and the Roland-Morris Disability Questionnaire (RMDQ) at 4 and 10 years post-injury.
• Statistical analysis was performed to compare scores and identify correlations with patient demographics and fracture characteristics.

Main Results:

• At 4 years post-injury, mean VAS was 74.5 and mean RMDQ was 4.9.
• At 10 years post-injury, mean VAS was 72.6 and mean RMDQ was 4.7 (not statistically significant difference from 4-year scores).
• Only 6% of patients experienced poor long-term outcomes, with no need for surgery due to late pain or neurological deficits.

Conclusions:

• Nonoperative management of type A spinal fractures provides good functional outcomes at both 4 and 10 years.
• Functional recovery appears to reach a plateau by 4 years and remains stable for at least 10 years.
• This suggests a favorable long-term prognosis for neurologically intact patients with type A spinal fractures treated conservatively.
