Lumbar Interbody Fusion: Techniques, Pearls and Pitfalls

Area of Science:

• Spine Surgery
• Orthopedics
• Neurosurgery

Background:

• Lumbar interbody fusion (LIF) is a common surgical treatment for degenerative spinal diseases.
• Various surgical approaches exist, including posterior, transforaminal, anterior, and lateral techniques, each with distinct advantages and disadvantages.
• Minimally invasive surgery (MIS) is increasingly utilized for LIF procedures.

Purpose of the Study:

• To provide a comprehensive description of different lumbar interbody fusion surgical techniques.
• To analyze the pearls and pitfalls associated with each LIF approach.
• To propose evidence-based indications and contraindications for each LIF method.

Main Methods:

• Detailed description of surgical procedures for posterior, transforaminal, anterior, and lateral LIF.
• Review of existing literature to identify advantages, disadvantages, and complication risks.
• Analysis of surgical outcomes, fusion rates, and approach-related challenges.

Main Results:

• Posterior LIF offers good fusion rates but risks neural and muscular injury.
• Transforaminal LIF (often MIS) reduces iatrogenic injuries.
• Anterior LIF (ALIF) restores alignment but has approach-related risks; lateral/oblique LIF (MIS) shows similar outcomes to ALIF but risks nerve and vascular injury.

Conclusions:

• Each lumbar interbody fusion approach has specific benefits and risks that must be carefully considered.
• Understanding the nuances of each technique is crucial for selecting appropriate surgical indications and contraindications.
• The choice of LIF approach should be tailored to the individual patient's condition and surgeon's expertise.
