Anterior Lumbar Interbody Fusion (ALIF) Surgery

• Anterior Lumbar Interbody Fusion (ALIF) surgery provides direct access to the intervertebral disk through the abdomen, making it a preferred technique for restoring vertical space between spinal vertebrae and reducing back pain.

• Ideal candidates for ALIF surgery are those with disc degeneration at lower lumbar segments, though morbidly obese patients or those with extensive prior abdominal surgeries may not be suitable.

• ALIF surgery involves various steps including preparation, minimally invasive surgical approach, disc removal and fusion with a bioplastic spacer, stabilization with metal screws and plates, and careful closure to ensure a successful outcome.

At Southern California Multi-Specialty Center, we are dedicated to advanced surgical procedures that give our patients a fresh lease on life. Anterior Lumbar Interbody Fusion (ALIF) is one of the procedures used in such cases, also known as anterior lumbar fusion. It is a surgical technique that involves approaching the lumbar spine through the abdomen to remove and replace a damaged disc.

This lumbar fusion procedure, specifically a spinal fusion where surgeons access the spine through the abdomen, aims to fuse lower back vertebrae. In contrast, posterior lumbar interbody fusion is a different approach to lumbar interbody fusion, which accesses the spine from the back.

ALIF surgery is often chosen over other procedures for the following reasons:

• It provides direct access to the intervertebral disk, thereby avoiding multiple surgeries in the same area.
• ALIF can restore the vertical space between spinal vertebrae compromised by lumbar disc degeneration.
• The surgery involves collaboration between an approach surgeon (abdominal or vascular) and a spine surgeon, ensuring the procedure is successful.

We aim to provide a comprehensive guide on ALIF surgery, including:

• Purpose of the surgery
• Ideal candidates for the procedure
• Procedural steps involved
• Benefits of ALIF surgery
• Risks and potential complications
• Recovery process and timeline

By equipping you with this knowledge, we at SCMSC hope to assist you in making informed decisions about your health.

Moreover, we wish to highlight the benefits of undergoing this procedure at the Southern California Multi-Specialty Center, where patient care and surgical excellence are our top priorities.

However, it’s important to note that not all patients are suitable for ALIF surgery. Morbidly obese patients or those who have undergone extensive prior abdominal surgeries may not be ideal candidates for this procedure. It’s crucial to consult with your doctor to evaluate your suitability for ALIF surgery.

The ALIF Procedure Steps

The ALIF procedure involves a series of steps, including preparation for surgery, the surgical approach, disc removal and fusion, stabilization, and closure.

Let’s delve deeper into each of these steps to understand what they entail.

Preparation for Surgery

Before the surgery, preoperative imaging tests, including MRI or CT scans, are performed to plan the procedure. These scans provide a detailed view of your spine, helping the surgeon identify the exact location of the problem.

Patients are also required to halt the intake of blood thinners and non-steroidal anti-inflammatory medicines a week before surgery. This is crucial to minimize bleeding during the procedure. Moreover, skin cleansing using Hibiclens or Dial soap is recommended to reduce the risk of infection.

Surgical Approach

During the minimally invasive surgery, the patient is positioned supine, and a 2- to 3-inch incision is made to access the spine. This anterior approach allows the surgeon direct access to the spinal cord without moving the nerves. However, it requires moving organs and blood vessels. To ensure safety, a vascular surgeon assists in moving aside the major blood vessels and clearing the path to the spine.

To plan the surgical approach accurately, surgeons use an X-ray fluoroscope or image guidance. These tools help ensure precision in the procedure. This advanced technology ensures precision and minimizes the risk of complications during the procedure.

Disc Removal and Fusion

Once the surgical approach is established, the next step involves removing the damaged disc. This is done using the following steps:

1. Use an instrument known as a distractor to open the disc space.
2. Remove the intervertebral disc.
3. The distractor helps prepare the disc space for the subsequent insertion of the bone graft or cage.

A bioplastic spacer cage filled with bone graft material is then inserted into the disc space. This spacer acts as a bridge between the two bones, promoting bone healing and fusion as the body heals. This process is crucial as it restores normal disc height and provides long-term stability.

Stabilization

After the bone graft or cage is inserted into the disc space, the next step involves stabilization. Metal screws and plates are used to provide stability during the fusion process. These screws secure the spacer graft in place during the ALIF surgery, ensuring a successful fusion.

In some cases, where additional stability is needed, a combined anterior and posterior approach may be necessary to achieve optimal spine stabilization. This comprehensive approach guarantees that the spine is adequately stabilized, promoting a successful recovery.

Closure

After the stabilization, the closure process begins. The peritoneum is re-expanded to its natural position before the abdominal muscle is closed with sutures. This careful process ensures that all organs are returned to their original position, minimizing the risk of postoperative complications.

The skin incision is then closed with skin glue, also known as Dermabond. This helps to seal the wound and promote healing. This marks the end of the ALIF procedure, and the patient is then moved to the recovery room for immediate postoperative care.

ALIF surgery offers several benefits that make it a preferred choice for treating lower back pain and associated leg pain. One of the primary benefits is the direct access it provides to the front of the spinal column. This allows for the placement of a larger cage, which increases stability and the likelihood of successful spinal fusion.

Additionally, ALIF can:

• Restore the vertical space between spinal vertebrae compromised by lumbar disc degeneration

• Increase the height of the disc space to achieve indirect decompression

• Create more room for the nerves to move freely in the canals

Furthermore, patients undergoing ALIF typically experience less pain and a faster recovery compared to surgeries performed from the back.

Like any surgical procedure, ALIF surgery carries certain risks and potential complications. These include:

• Bleeding

• Infection

• Stroke

• Coma

• Heart attack

• In rare cases, death.

Specific to ALIF surgery, risks include:

• Blood vessel damage

• Bowel injury

• Nerve damage

• The potential need for additional surgeries

The complication rates for ALIF surgery range from 1% to 15%. It’s also worth noting that ALIF surgery is more challenging and riskier at upper lumbar levels, making LLIF or TLIF better options for these areas.

The recovery process after ALIF surgery is an essential part of the journey to a pain-free life. It involves immediate postoperative care, long-term recovery, and pain management.

Immediate Postoperative Care

Immediately after the surgery, vital signs such as blood pressure, heart rate, and respiration are closely monitored. This vigilant monitoring ensures that the patient is stable and recovering well from the procedure.

Patients are also encouraged to begin gentle movements such as sitting in a chair or walking shortly after ALIF surgery as a form of physical therapy. Early mobility aids in the recovery process and helps prevent postoperative complications such as blood clots.

Long-term Recovery

The long-term recovery process after ALIF surgery varies from patient to patient, depending on factors such as general health, age, and the specific condition being treated. Most patients can generally resume light desk jobs or household activities within 2-3 weeks following surgery. This can depend on individual recovery and medical advice..

However, patients are advised to avoid bending, lifting, and twisting for 2 to 3 months after ALIF surgery. Return to heavy lifting or strenuous activities is allowed after 8-12 weeks, pending approval from the doctor. It’s essential to follow the surgeon’s instructions for a smooth and successful recovery.

Pain Management

Pain management is a critical aspect of the postoperative recovery process. Patients are often prescribed narcotic pain medication after ALIF surgery to alleviate discomfort. However, these medications should be reduced as pain subsides.

In addition to medications, ice packs are recommended 3-4 times daily for 15-20 minutes to reduce pain and swelling after ALIF surgery. These simple yet effective pain management strategies can significantly aid in your recovery process.

The success rates and outcomes of ALIF surgery are quite promising. Most studies show that ALIF leads to successful fusion between the vertebrae in over 90% of cases. In fact, many studies report rates of successful fusion greater than 95%.

However, it’s important to note that the success of achieving spinal fusion in ALIF spinal fusion surgery is influenced by factors such as the surgical technique used, the patient’s general health, and their smoking status. Despite these factors, most patients report significant improvement in their back pain and overall quality of life after undergoing spinal fusion surgery, specifically ALIF surgery.
