01 — Overview
A conventional lateral interbody fusion is performed with the patient on their side, then repositioned prone for the screws. Performing the lateral approach with the patient already prone means the spine is in its lordotic posture when the implant is placed, and removes a position change from the middle of the operation.
02 — Who it suits
- Degenerative scoliosis requiring correction at several levels
- Loss of lumbar lordosis
- Degenerative disease across the upper and mid lumbar spine
- Cases where restoring disc height relieves the nerve canals indirectly
03 — How it is done
With the patient prone, a lateral corridor is developed through the psoas under nerve monitoring. The disc is removed and an interbody cage restores height and lordosis. Posterior screws are then placed without repositioning.
04 — Recovery
Temporary hip flexor weakness or numbness over the front of the thigh on the approach side can occur and usually settles. Walking is generally encouraged early.
05 — Conditions treated
- Scoliosis & Spinal Deformity An abnormal lateral curvature of the spine, which can lead to pain, deformity, and respiratory issues if severe.
- Degenerative Disc Disease A condition where the spinal discs wear down over time, leading to pain, stiffness, and potential nerve compression.
- Spinal Stenosis A narrowing of the spinal canal that compresses the spinal cord and nerves, causing pain, numbness, and weakness.
Timelines and techniques described here are general. Your own plan depends on your anatomy, your imaging and your medical history, and is decided with you at consultation.
