Lateral spine surgery, also known as lateral lumbar interbody fusion (LLIF) or direct lateral interbody fusion (DLIF), is a minimally invasive procedure used to treat various spinal conditions such as degenerative disc disease, spinal stenosis, and scoliosis. This surgery involves accessing the spine from the side of the body rather than the front or back. The procedure offers advantages such as less muscle dissection, reduced blood loss, and quicker recovery times compared to traditional spine surgery.
Conditions Treated with Lateral Spine Surgery
Degenerative Disc Disease: The breakdown of intervertebral discs, causing pain and stiffness in the lower back and affecting mobility.
Spinal Stenosis: Narrowing of the spinal canal, leading to pressure on the spinal cord or nerves, resulting in pain, weakness, and numbness.
Scoliosis: Abnormal curvature of the spine, which can cause pain and affect posture, especially in adults.
Herniated Discs: When a disc in the spine bulges or ruptures, placing pressure on nerves and causing pain, tingling, or weakness in the legs.
Benefits of Lateral Spine Surgery
Minimizes muscle disruption due to access from the side, leading to quicker recovery.
Reduced risk of blood loss and lower complication rates compared to traditional open surgery.
Less postoperative pain, allowing patients to resume normal activities sooner.
Smaller incisions and less scarring due to the minimally invasive nature of the procedure.
Effective for treating conditions that may not be accessible via traditional anterior or posterior approaches.
Procedure of Lateral Spine Surgery
Incision: A small incision is made on the side of the body, usually between the ribs and pelvis, to access the spine.
Dissection: Muscles and soft tissues are gently moved aside to allow access to the spine without cutting through them.
Spinal Repair: The surgeon removes or repairs the damaged disc, and may use an interbody cage or spacer to restore the normal height of the vertebrae.
Fusion: In some cases, the vertebrae may be fused to provide stability, often using screws and rods to secure the spine.
Recovery: Patients usually experience quicker recovery times and less pain, with many able to resume light activities within a few weeks.
Risks and Considerations of Lateral Spine Surgery
Infection at the incision site
Damage to nearby nerves, blood vessels, or organs
Blood clots or bleeding complications
Failure to relieve symptoms or recurrence of spinal issues
Potential nerve injury due to the close proximity of spinal nerves
Lateral spine surgery offers a minimally invasive alternative to traditional spine surgeries, with many benefits, including faster recovery and less pain. However, it is crucial to discuss with a spine specialist whether this procedure is suitable for your specific condition and health needs.
