Anterior Cervical Discectomy and Fusion

Anterior cervical discectomy and fusion (ACDF) is a procedure used to reduce the movement and instability caused by deteriorating cartilage or bulging discs.


Disc Replacement Surgery

An artificial disc—also called a disc replacement—is a device that is implanted into the spine to imitate the functions of a normal disc.


Lumbar Fusion

Lumbar fusion is a surgical procedure that is performed to permanently connect two or more vertebrae in the lumbar spine to improve stability, correct a deformity or reduce pain.


Lumbar Microdiscectomy

A lumbar microdiscectomy is a minimally invasive procedure for removing the herniated portion of a disc that is pressing on a spinal nerve root and causing leg pain, back pain, and other issues.


Minimally Invasive Spine Surgery

The goal of minimally invasive spine surgery (MIS) surgery is to stabilize the vertebral bones and spinal joints and/or relieve pressure being applied to the spinal nerves — often a result of conditions such as a spinal instability, bone spurs, herniated discs, scoliosis or spinal tumors.


Spinal Cord Stimulation

Spinal Cord Stimulation (SCS) therapy helps mask pain signals before they can reach the brain. A spinal cord stimulator (SCS) device is implanted under the skin to deliver a low-voltage electrical current continuously to the nerve fibers of the spinal cord.
