Open anterior approaches for lumbar spine procedures

Area of Science:

• Spinal surgery
• Anatomy
• Surgical techniques

Background:

• Anterior lumbar interbody fusion (ALIF) and artificial disc replacement are common for spinal issues like degenerative disc disease.
• Anterior exposure for spinal procedures is increasingly performed by various surgical specialists.
• A significant gap exists in the literature detailing these anterior surgical approaches.

Purpose of the Study:

• To provide a comprehensive guide to the anatomical and technical aspects of anterior spinal surgery.
• To detail open surgical approaches for specific lumbar disc spaces (T12-L2, L2-5, L5-S1).
• To discuss the retroperitoneal approach, indications for the transperitoneal approach, and offer technical insights.

Main Methods:

• The study divides anterior spinal surgery approaches into thoracolumbar, mid-lumbar, and lumbosacral regions.
• Detailed descriptions of the anatomy and basic techniques for open approaches are provided.
• The retroperitoneal approach is discussed in detail, with considerations for the transperitoneal approach.

Main Results:

• The paper outlines the specific anatomical considerations for accessing disc spaces T12-L2, L2-5, and L5-S1.
• It details the retroperitoneal approach for anterior spinal exposure.
• Key technical pearls and indications for alternative approaches are presented.

Conclusions:

• This work aims to fill the literature gap by providing essential knowledge for anterior spinal surgery.
• Surgeons can utilize this guide to safely and effectively perform anterior approaches to the lumbar spine.
• Understanding regional anatomy and surgical techniques is crucial for successful outcomes in anterior spinal procedures.
