Biportal endoscopic transforaminal lumbar interbody fusion using a large cage for degenerative spondylolisthesis with stenosis

Dong Hwa Heo

Recently, biportal endoscopic transforaminal lumbar interbody fusion (TLIF) has been used to treat lumbar degenerative diseases, such as lumbar instability and spondylolisthesis. Biportal endoscopic TLIF may have the advantages of endoscopic spine approaches and minimally invasive lumbar fusion surgeries. In this biportal endoscopic TLIF, large cages similar to oblique lumbar interbody fusion (OLIF) cages have been used. Biportal endoscopic TLIF using a large cage can be successfully performed in the lower lumbar area. The author presents the surgical technique of biportal endoscopic TLIF using a large cage.

Biportal endoscopic posterior cervical foraminotomy with discectomy for unilateral radicular arm pain due to cervical herniated disc

Dong Hwa Heo

Recently, biportal endoscopic cervical approaches have been used to treat cervical degenerative disease. Biportal endoscopic posterior cervical foraminotomy with or without discectomy has the advantage of reducing damage to the normal tissues during surgery and enhancing fast recovery after surgery. The biportal endoscopic cervical approach was performed using two portals. The first portal was an endoscopic viewing portal for the spinal endoscope, and the other portal was a working portal for using surgical instruments. The author illustrates the surgical technique of biportal endoscopic posterior cervical foraminotomy with discectomy.
