Treatment
Joining two vertebrae to stop painful motion — used only when the spine is genuinely unstable, and only after gentler options have been exhausted.
Fusion permanently joins two vertebrae so they heal into a single, solid unit, ending the painful motion between them. Stabilization hardware holds that segment steady while it heals. Done for the right reason, it can settle pain that comes from a spine that has become genuinely unstable.
Dr. Melamed treats fusion as a considered last resort, not a first move. Before he recommends it, decompression, motion-preserving surgery, and conservative care are weighed and, where appropriate, tried first — because fusing a segment gives up its motion for good. When fusion truly is the right answer, he performs it with minimally invasive technique where the case allows, sparing muscle and preserving as much healthy tissue as possible.
In the lower back, that usually means an interbody fusion reached from the side (XLIF) or from the front (ALIF), chosen level by level. XLIF suits many of the upper and middle lumbar levels, while ALIF is usually the better route at the bottom level, L5-S1. Neither one cuts the back muscles, and some patients need a combination of the two.
The process is similar to “welding” bones together. Specialized instrumentation—such as screws, plates, and rods—holds the bones in position while the body naturally heals and fuses the area. The result is restored spinal stability.

Fusion is reserved for true instability — an unstable spondylolisthesis where one vertebra is slipping on another, deformity that needs to be held in a corrected position, or a segment that has failed after prior surgery. It is not the answer for a simple pinched nerve or a disc problem that motion-preserving options can handle. Dr. Melamed confirms real instability on imaging before recommending it, so the operation matches the diagnosis.
Spinal fusion surgery is often recommended for patients who experience chronic back or neck pain due to instability or deformity of the spine that has not improved with conservative treatments. Most candidates have already tried physical therapy, injections, or other non-surgical interventions without sufficient relief.
The goal is to eliminate the movement between damaged vertebrae that causes pain, nerve compression, or deformity.
At The Spine Pro, Dr. Melamed tailors every surgical plan to the patient’s individual anatomy, condition, and lifestyle goals.
Modern spinal fusion procedures have evolved to minimize trauma, reduce recovery time, and improve precision. Common approaches include:
Dr. Melamed also performs artificial disc replacement, an alternative to fusion that maintains natural motion by replacing a damaged disc with a synthetic one. To achieve optimal stability and long-term results, the chosen technique is tailored to the distinct spinal anatomy of each patient.
The unstable segment is stabilized and the two vertebrae are prepared so they knit together over time, often with a spacer to restore height and hardware to hold the alignment while the bone heals into one unit. Any nerve compression at that level is relieved in the same procedure.
Where the anatomy allows, Dr. Melamed uses a minimally invasive approach — small openings and muscle-sparing exposure — rather than a large open dissection. This reduces tissue disruption and supports a smoother recovery, though the fusion itself remains a permanent change to that segment.
The entire procedure typically takes 3 to 6 hours and is performed under general anesthesia. Thanks to modern minimally invasive techniques, smaller incisions and less tissue disruption mean reduced scarring and faster healing.
Postoperative care includes walking and light activity soon after surgery, helping to prevent stiffness and blood clots. Most patients return home within 24–48 hours, depending on the complexity of their procedure.
Because fusion relies on bone healing into a solid bridge, recovery is a gradual, staged process measured in weeks to months rather than days. A minimally invasive approach spares muscle and typically eases the early recovery. Dr. Melamed guides you through progressive activity and rehabilitation, with a deliberate effort to limit narcotics along the way.
Recovery after spinal fusion is a gradual process that requires patience and guided care. Initial bone healing begins around 6 weeks post-surgery, while full fusion and strengthening can take 3 to 6 months.
In most cases:
Follow-up visits and imaging ensure that fusion is progressing correctly. Many patients experience a dramatic reduction in pain and improved mobility within weeks. For complex cases, a full recovery may take up to one year.
Success rates range from 60 to 95%, depending on the condition and surgical approach. For a TLIF, success rates range from 60 to 70%, and reports indicate a 90-95% success rate for PLIF.
Advancements in navigation-assisted systems, patient-specific implants, and cellular therapy have revolutionized the field—allowing surgeons to achieve precise alignment and faster fusion. According to recent data, the average age of spinal fusion patients has decreased from 56.6 years in 2019 to 54.1 years in 2023, which also reflects a wider adoption among younger adults with degenerative spine conditions.
At The Spine Pro, technology and compassion go hand in hand. Every procedure is guided by the principle of “treating the person, not just the spine.”

Questions, Answered
Not with Dr. Melamed. He treats fusion as a last resort and first weighs decompression, motion-preserving surgery, and conservative care. He only recommends fusion when imaging confirms true instability that those gentler options cannot address.
Fusing a segment does give up its motion permanently — that is the point when the motion itself is the source of pain. The rest of your spine continues to move, and the goal is that stopping motion at the unstable level relieves more pain than the lost motion costs you.
No. Dr. Melamed picks the approach per level. XLIF reaches the spine from the side and suits many upper and middle lumbar levels. ALIF reaches it from the front and is usually best at L5-S1. Both spare the back muscles, and some patients need both.
In many cases, yes. Where the anatomy allows, Dr. Melamed uses small openings and muscle-sparing exposure rather than a large open dissection, which reduces tissue disruption and supports a smoother early recovery.
