Non neurologic burst thoracolumbar fractures fixation: Case-control study

Area of Science:

• Orthopedic surgery
• Spinal trauma management
• Biomechanics of vertebral fractures

Background:

• Unstable thoracolumbar burst fractures without neurological deficits lack treatment consensus.
• Current management strategies for these fractures vary, leading to therapeutic uncertainty.

Purpose of the Study:

• To compare the efficacy of posterior short-segment fixation with kyphoplasty (SFK) versus long-segment fixation (LF) for A3 thoracolumbar unstable fractures.
• To guide therapeutic decisions in managing these specific spinal injuries.

Main Methods:

• A retrospective case-control study evaluating 25 patients treated with SFK.
• Comparison with a control group of 82 patients treated with LF pedicle screws.
• Analysis of fracture characteristics, surgical outcomes, and patient recovery.

Main Results:

• SFK group demonstrated significantly less blood loss (p=0.04) and increased endplate height (p=0.006).
• SFK patients reported significantly improved pain levels (p=0.002) and earlier postoperative mobilization (1.7 vs 3.7 days, p=0.001).
• No significant difference in deformation progression, vertebral height restoration, or kyphotic angle reduction between SFK and LF groups.

Conclusions:

• SFK is as effective as LF for bone consolidation and spine stabilization in A3 thoracolumbar fractures.
• SFK may lead to reduced analgesic requirements and faster recovery.
• SFK presents a viable alternative for managing selected unstable thoracolumbar burst fractures.
