Long-Term Outcomes of Minimally Invasive vs. Traditional Open Spinal Fusion: A Comparative Analysis

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Spinal Disorders

Background:

• Spinal fusion is a common procedure for spinal conditions.
• Open spinal fusion is the traditional method.
• Minimally invasive spinal fusion (MISF) is an alternative aiming for reduced trauma and faster recovery.

Purpose of the Study:

• To compare long-term outcomes of MISF versus traditional open spinal fusion.
• To evaluate perioperative results, pain relief, functional recovery, fusion rates, and cost-effectiveness.
• To identify research gaps and future directions in MISF.

Main Methods:

• Systematic literature review and critical examination of existing studies.
• Comparison of perioperative data, long-term clinical outcomes, and cost-effectiveness analyses.
• Focus on fusion rates, complication risks, and adjacent segment disease (ASD).

Main Results:

• MISF shows reduced blood loss, shorter hospital stays, and lower infection rates, but potentially longer surgical times and a steeper learning curve.
• Long-term clinical outcomes, including fusion rates and improvements in pain and function, appear comparable between MISF and open fusion.
• The impact of MISF on adjacent segment disease is inconclusive; cost-effectiveness may favor MISF in the long term.

Conclusions:

• MISF is a viable alternative to open spinal fusion with comparable long-term results.
• Further high-quality, long-term randomized controlled trials are necessary to address current research limitations.
• Optimizing surgical decision-making and patient outcomes requires further investigation into MISF's long-term effects and biomechanics.
