Lateral transpsoas fusion: indications and outcomes

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Spinal fusion is a common surgical procedure.
• The lateral transpsoas approach is a newer technique for thoracic and lumbar spine fusion.
• This approach presents potential benefits over traditional methods.

Purpose of the Study:

• To review the advantages of the lateral transpsoas approach.
• To discuss expanded indications for this procedure.
• To analyze complication rates and unique risks associated with lateral interbody fusion.

Main Methods:

• Literature review of recent studies on the lateral transpsoas approach.
• Comparison of lateral interbody fusion with traditional anterior and posterior approaches.
• Analysis of reported indications, outcomes, and complications.

Main Results:

• The lateral transpsoas approach offers benefits such as reduced tissue dissection, potentially lower blood loss, no need for an access surgeon, and shorter hospital stays.
• Indications have broadened to include degenerative disc disease, spinal stenosis, scoliosis, nonunion, trauma, infection, and spondylolisthesis.
• Complication rates are comparable or lower than traditional methods, but unique risks like transient neurologic symptoms and motor deficits exist.

Conclusions:

• The lateral transpsoas approach is an increasingly utilized method for spinal fusion with several advantages.
• While generally safe, unique neurological complications require careful consideration and monitoring.
• Further research is necessary to fully understand the long-term safety, efficacy, and outcomes of this technique.
