Lumbar & Cervical Spinal Fusion

Clinical success rates exceed 95% with expert surgical technique and physical therapy.

Yes, because the fused vertebrae will no longer move independently. However, the degree of limitation depends heavily on the number of levels fused and the region of the spine. A single-level lumbar fusion often results in very little noticeable loss of mobility, as the surrounding joints compensate. Fusing multiple segments will result in a more noticeable decrease in range of motion.

While you may leave the hospital in 1 to 4 days, the actual biological fusion of the bones takes 3 to 6 months to become solid, and up to a year to fully mature. During the first 4 to 6 weeks, you will have strict restrictions against bending, lifting (anything over 10 lbs), and twisting (the "BLT" restrictions). Most patients can return to desk jobs in 4 to 6 weeks, but heavy physical labor may require 3 to 6 months of recovery.

This is a complication known as "pseudarthrosis" or nonunion. If the bone graft fails to bridge the gap and fuse the vertebrae, the metal hardware may eventually loosen or break due to continuous stress, often requiring a second revision surgery. Smoking, obesity, diabetes, and certain medications (like NSAIDs) significantly increase the risk of nonunion.

Because the fused segment of the spine no longer moves, the spinal discs and joints immediately above and below the fusion have to absorb extra stress and movement. Over time, this increased mechanical load can accelerate wear and tear on those adjacent segments, potentially leading to pain or the need for further surgery years down the line.
