Lumbar Disc Herniation (Herniated Disc)

A lumbar disc herniation occurs when the soft inner core (nucleus pulposus) of an intervertebral disc pushes through its outer ring (annulus fibrosus) and compresses a nearby nerve root. It is most common at the L4-L5 and L5-S1 levels and is a frequent cause of sciatica — pain radiating from the lower back into the leg.

Cervical Disc Herniation (Neck Hernia)

A cervical disc herniation occurs when a disc in the neck region protrudes and compresses a nerve root or the spinal cord. It is most common at the C5-C6 and C6-C7 levels and typically causes pain radiating into the arm, with numbness and weakness.

Endoscopic Discectomy

Endoscopic discectomy is a minimally invasive surgical technique in which the fragment of a herniated disc compressing a nerve root is removed using an endoscope inserted through a small incision. The aim is to preserve muscle and allow faster recovery.

Microdiscectomy

Microdiscectomy is a microsurgical disc removal technique performed through a posterior approach under the operating microscope to relieve a herniated disc fragment pressing on a nerve root. It is most often used in the lumbar spine, and less commonly the cervical spine, to reduce radicular pain.

Anterior Cervical Discectomy and Fusion (ACDF)

ACDF is a common spine operation in which a diseased cervical disc is removed through an anterior (front) approach to the neck and the resulting space is filled with a graft/implant to fuse two vertebrae together. The goal is to relieve disc and bony structures compressing a nerve root or the spinal cord.

Endoscopic Cervical Discectomy

Endoscopic cervical discectomy is a minimally invasive surgical technique in which a disc fragment compressing a nerve root in the neck is removed using an endoscope inserted through a small incision. In selected cases it aims to preserve motion without fusion and to reduce tissue damage.
