Interspinous fusion using a lateral approach is minimally invasive surgery for relieving back and leg pain due to lumbar spinal stenosis, or narrowing of the spinal canal. The goal is to stabilize the spine and relieve nerve pressure. A small side incision minimizes back muscle damage, sparing the supra-spinous ligament. A metal device is placed between the back bones, known as the spinous processes, to stabilize the spine. This, along with a bone graft, helps the bones fuse over time for permanent support. Typically, this is an outpatient same-day surgery.

Before surgery, your surgeon will review your medical history, and MRI or CT scans will ensure the suitability of this approach. It's crucial to stop blood-thinning medications and halt solid foods 8 hours before and clear liquids 2 hours prior. Post-surgery, many patients feel immediate pain relief, but rest and limited activity are essential for healing. Recovery includes starting physical therapy a few weeks after surgery to regain strength and mobility, with full recovery possibly taking several months.

Alternatives include other spinal fusion surgeries performed from the front, back, or side, though these often involve more extensive surgery and longer recovery. Risks include infection, implant failure, or pseudarthrosis, where bones don't fully fuse. Those with severe osteoporosis or active infections may not be ideal candidates. Your surgeon and medical team will monitor for complications, and following postoperative instructions is key for the best outcome. Our team is dedicated to guiding you to the best treatment.
