Interspinous fusion using a midline approach is a surgical procedure for back issues like lumbar spinal stenosis, where the spinal canal narrows and presses on nerves. It involves inserting a stabilizing device between the spine's bony parts, known as spinous processes, to ease nerve pressure and create a stable healing environment.

A small incision is made in the middle of the back during the procedure. The surgeon removes some bone and tissue to relieve spinal nerve pressure. Then, a metal device is placed between spinous processes to provide stability while allowing some motion. A bone graft, taken from your body or donated, is also used to promote bone healing and fusion over time.

Patients typically undergo this procedure for chronic low back pain, nerve root pain, or neurogenic claudication, where pain occurs while walking. Compared to traditional surgery, this method is less invasive, often resulting in a shorter hospital stay—typically 1 to 2 days—and faster recovery, sometimes going home the same day. Physical therapy is recommended to restore strength and flexibility around 6 weeks post-surgery, with a return to light activity in a few months.

Alternatives include the MILD procedure, which removes thick ligaments without placing devices, and interspinous spacers, non-fusion devices for stabilization. Traditional open surgeries may be needed for severe cases needing extensive stabilization.

All surgeries have risks, such as nerve damage, device migration, or spinous process fracture. It's not suitable for everyone, especially those with severe osteoporosis or needing multiple levels of fusion. Our team will discuss if this surgery is right for you and explain your options.
