When a segment of the spine is unstable or its motion is the source of pain, joining it into one solid, stable unit can bring lasting relief. See exactly how a fusion works below — then learn how Dr. Hobbs does it with minimally invasive, image-guided precision.
Call (219) 250-5010Spinal fusion permanently joins two or more vertebrae so they heal into a single, solid bone. By removing the painful, unstable motion at that segment — the way a cast lets a broken bone knit together — fusion can relieve pain and restore stability. It is used for conditions such as spondylolisthesis, instability, deformity, fractures, and severe disc degeneration.

A fusion is only as good as its accuracy and alignment. Dr. Hobbs pairs minimally invasive technique with technology that plans and verifies every step.

Dr. Hobbs on where personalized implants go next
Patient-specific planning belongs in community spine care for the right patients, he told Becker’s, with access decided by clinical need rather than ZIP code and with evidence, not promise, guiding adoption. Conventional implants remain effective; the goal is precision, not customization for its own sake.
The hardware does its job immediately. The bone takes longer. Here is how the two timelines fit together.
The hardware provides immediate stability, so most patients are up and walking soon after surgery. Light daily activities resume over the first few weeks, with limits on heavy lifting, bending, and twisting while the fusion heals.
This is when the bone actually fuses. Activity is gradually increased and physical therapy helps rebuild strength and flexibility. Dr. Hobbs confirms healing with follow-up imaging.
Once the segment is solidly fused, the painful motion is gone for good. Recovery timelines vary with the number of levels treated and individual healing; Dr. Hobbs tailors a plan to you.
