Application of Stand-Alone Oblique Lateral Interbody Fusion in L4-5 Lumbar Diseases

Summary

This study describes the application of oblique lateral interbody fusion in lumbar spinal surgeries.

Abstract

Lumbar spine diseases often cause lower back pain, lower extremity pain, numbness, and paresthesia. In severe cases, intermittent claudication may occur, affecting the quality of life of patients. Surgery is often required when conservative treatment fails, or when patients' symptoms become unbearable. Surgical treatments include laminectomy and discectomy, as well as interbody fusion. The main purpose of laminectomy and discectomy is to relieve nerve compression; however, recurrence is common due to spinal instability. Interbody fusion improves stability while relieving nerve compression and significantly reduces the risk of recurrence compared to non-fusion surgery. Nonetheless, conventionally posterior intervertebral fusion requires separation of the muscles to expose the operated segment, which causes more trauma to the patient. In contrast, the oblique lateral interbody fusion (OLIF) technique achieves spinal fusion with minimal trauma to the patients and shortens the recovery time. This article introduces procedures of stand-alone OLIF surgery performed in the lumbar spine, providing a reference for other spine surgeons.

Introduction

Lumbar spine disorders are a global economic concern, with affected patients experiencing lower quality of life¹. The treatment of lumbar spine diseases can be divided into two categories: conservative and surgical treatment. Conservative treatment includes rest, oral nonsteroidal drugs, massage, and physical therapy. For instance, studies have shown that estrogen can be used to delay degeneration of the intervertebral disc, thus providing a basis for its treatment of lumbar spine disease^2,3. For patients who have failed in conservative treatment, surgery is typically required to treat ....

Protocol

This study has been approved by the Ethics Committee of the Third Hospital of Hebei Medical University. The patients signed informed consent, consented to be filmed, and allowed the investigators to use their surgical data.

1. Patient selection

1. Select patients based on the following inclusion criteria.
   1. Select patients for whom conservative treatment time was longer than 3 months and to which the patients responded poorly.
   2. Select patients whos.......

Discussion

Since formally introduced by Silvestre in 2012²³, OLIF has gradually attracted the attention of spine surgeons due to the various advantages over other methods used in treating lumbar spine diseases^{6,12,13,16,21,22}. OLIF significantly improved patients' disc height and lordotic angle, which may be due .......
