Surgery or Bracing for Burst Fractures: No Difference?

Key Takeaways

• PROST scores rose from ~35‑40 baseline to 86 for both groups
• No statistical difference at 3 months, 1 year, or 2 years
• Surgery provides slight early functional boost, but advantage fades
• Nonoperative treatment avoids implants and operating‑room costs
• Patient‑centered choice can focus on early recovery priorities

Pulse Analysis

Thoracolumbar burst fractures represent a common high‑energy spinal injury, often leaving surgeons torn between operative fixation and conservative bracing. Historically, decisions have hinged on radiographic stability, surgeon experience, and institutional protocols, while patient‑reported outcomes received limited attention. The AO Spine PROST tool, designed specifically for spine trauma, fills this gap by quantifying functional recovery in everyday life, offering a more nuanced view than generic disability indices.

The prospective, multicenter cohort followed 93 adults aged 18‑65 across diverse practice settings, allowing real‑world treatment choices rather than forced randomization. Baseline PROST scores averaged 34 for non‑operative patients and 40 for those undergoing instrumentation. Both groups surged to a mean of 86 by two years, indicating excellent functional restoration. A modest early advantage emerged for surgery at the three‑month mark, but the gap narrowed rapidly, culminating in statistical parity at one and two years. These results underscore that, for neurologically intact patients, the long‑term functional trajectory is remarkably similar regardless of treatment modality.

Clinically, the study challenges the assumption that operative care inherently yields superior outcomes, highlighting potential cost savings, reduced implant‑related complications, and avoidance of operating‑room resources. It also empowers shared decision‑making: clinicians can discuss early pain relief and mobilization benefits of surgery versus the convenience and lower expense of bracing, aligning the choice with each patient’s personal priorities. As value‑based care gains traction, such evidence may reshape guidelines, encouraging a more individualized, outcome‑focused approach to thoracolumbar burst fracture management.
