Informed Consent for Spinal Fusion Surgery

Patient and Surgical Information

Nature and Purpose of the Procedure

Spinal fusion is a major surgical procedure performed to permanently connect two or more vertebrae in the spine, eliminating motion between them. It is indicated for conditions such as spinal instability, spondylolisthesis, severe degenerative disc disease, scoliosis, or stenosis that has failed conservative care. Under general anesthesia, the surgeon accesses the spine (via an anterior, posterior, or lateral approach). If nerve compression is present, a laminectomy or discectomy is performed to relieve pressure. The surgeon places specialized hardware (screws, rods, plates, or interbody cages) to stabilize the spine. Bone graft material (harvested from the patient's hip bone or local surgical site, or obtained from a donor tissue bank, sometimes supplemented with bone morphogenetic proteins) is packed between the vertebrae. Over several months, the bone graft grows and fuses the vertebrae into a single solid bone. The procedure typically takes 2 to 6 hours.

Material Risks and Potential Complications

Infection: superficial wound infection or deep spinal space infection, which is serious and may require surgical washing, hardware removal, or long-term IV antibiotics.
Excessive bleeding or dural tear: tear of the sac containing spinal fluid (cerebrospinal fluid leak), which may cause severe headaches and require surgical repair or bed rest.
Pseudarthrosis (failure to fuse): the vertebrae failing to solid-fuse together, which occurs in 5 to 15 percent of cases, especially in smokers or patients with diabetes. This may cause chronic pain and require repeat revision surgery.
Nerve damage or spinal cord injury: injury to the nerve roots or spinal cord causing new or worsening pain, numbness, weakness, foot drop, or in extremely rare cases, bowel/bladder incontinence or paralysis.
Hardware failure or loosening: pedicle screws or rods breaking, shifting, or backing out before fusion occurs, requiring surgical revision.
Adjacent segment disease: increased stress and accelerated degeneration of the spinal discs above or below the fused segments, which may require surgery in the future.
Chronic donor site pain: persistent pain or numbness at the hip bone site if an iliac crest autograft was harvested.

Reasonable Alternatives

Non-surgical management: specialized physical therapy, core stabilization exercises, and back education.
Interventional pain management: epidural steroid injections, facet joint blocks, or radiofrequency ablation.
Decompression surgery alone: performing a laminectomy or microdiscectomy without fusion, if spinal instability is not present.
No surgery: accepting limitations, using spinal orthotic braces, and optimizing pain medications.

Critical Nicotine and Smoking Warning

Nicotine is a potent vasoconstrictor that severely inhibits bone healing and blood supply. Clinical studies demonstrate that active smoking or nicotine use (including e-cigarettes, patches, or gum) increases the risk of pseudarthrosis (failed fusion) by up to 3 to 4 times. Patients are strongly advised to cease all nicotine use for at least 4 to 6 weeks before and at least 6 months after spinal fusion surgery to ensure successful bone healing.

Questions and Understanding Confirmation

I confirm that I have had the opportunity to read this consent form carefully and discuss the surgical plan with my surgeon. I understand the critical importance of nicotine cessation for bone healing. I believe I am making an informed and voluntary decision.
