L4-L5 Fusion: Success Rate and Recovery
Spinal fusion is a longstanding procedure that stabilizes the spine and helps alleviate symptoms of various spinal conditions. Though it may be done on virtually any part of the spine, fusion is commonly done on the L4-L5 segment of the lumbar spine.

This article will explore the success rate, recovery process, and available alternatives for L4-L5 fusion.
What is L4-L5 Fusion Surgery?
L4-L5 fusion involves fusing the L4 and L5 vertebrae in the lumbar spine. It’s commonly performed to treat lumbar spine conditions including spinal stenosis, spondylolisthesis, disc degeneration, vertebral fractures, and herniated disc.
The spine consists of four sections: the cervical spine (the neck), the thoracic spine (the mid-back), the lumbar spine (the lower back), and the sacral spine (directly above the tailbone). Each of the vertebrae of the spine has been assigned a letter and a number according to these sections. The lumbar spine includes the L1 through the L5 vertebrae.
Spinal fusions are most commonly performed on the lumbar spine. Over 300,000 lumbar spine procedures are estimated to be performed in the United States each year.
How Long to Recover from L4-L5 Fusion?
It takes between six months and one year to fully recover from L4-L5 fusion. You may need four to six weeks to return to basic activities around the house after the procedure, and one to two months to return to work.
If your job involves light physical activity, you may need to take three to six months off of work after L4-L5 fusion. Patients whose jobs require hard physical labor generally can’t return to those occupations after the procedure.
Fusion requires such a lengthy recovery process because it involves bone healing. Bone tissue takes longer to heal than soft tissue.
How to Wash Hair After Spinal Fusion Surgery on L4-L5?
To wash your hair after L4-L5 spinal fusion, use a hand-held shower head. If you don’t have one, bend at the knees and waist to fit your head under the shower head. Make sure not to arch your back to wash your hair after fusion, as doing so may strain your spine.
Additionally, consider purchasing a long-handled shower brush before undergoing lumbar fusion. With this tool, you can wash all areas of your body without bending. Many fusion patients also benefit from using liquid soap after fusion to prevent having to pick up a fallen bar of soap.
After L4-L5 spinal fusion, basic tasks like washing your hair may be extremely difficult. To combat this, take the following steps to prepare your home before the surgery:
- Move items in your kitchen and bathroom off of the high shelves so that you won’t have to strain to reach them.
- Stock your kitchen with nutritious ready-made meals so that you don’t have to worry about cooking while you recover.
- Do all of your laundry and set out comfortable clothes to wear during the early stages of your spinal fusion recovery.
What to Expect After L4-L5 Fusion?
After L4-L5, you can expect to stay in the hospital for two to three days. Additionally, expect to experience stiffness and soreness in the lower back. Your doctor will likely prescribe pain medication to ease discomfort in the first few days or weeks after the procedure.
You’ll be advised to avoid lifting, bending, and twisting your spine for at least two weeks after L4-L5 fusion. Most patients are told to avoid lifting any objects heavier than five pounds for at least two weeks after spinal fusion.
As aforementioned, expect to take four to six weeks off of work after L4-L5 fusion (or longer, if your occupation requires physical exertion).
What is The Success Rate for L4-L5 Spinal Fusion?
The estimated success rate of lumbar spinal fusion is 70% to 90%. This rate can vary depending on the condition that the procedure’s used to treat.
How Successful is Lumbar Fusion Surgery L4-L5?
Lumbar fusion surgery at the L4-L5 spinal segment is considered a long-standing and widely successful procedure. However, the success of L4-L5 fusion depends on both the fusion of the vertebrae and the patient’s symptom improvement. Spinal fusions rarely provide a total cure for the patient’s back and leg pain.
Certain factors can reduce the chance of success in L4-L5 lumbar fusions. These factors include:
- Smoking or using other nicotine products
- Obesity
- Osteoporosis
- Some chronic conditions
- Engaging in strenuous activities during the recovery process
What Are The Risks of L4-L5 Spinal Fusion?
The risks of L4-L5 spinal fusion include:
- Failure of the bone to fuse
- Hardware failure
- Nerve injury
- Adjacent segment disease
- Lingering lower back pain
- Need for reoperation
These risks accompany the risks associated with all surgical procedures, including infection at the surgical site, thrombosis, and complications from anesthesia.
The Best Modern Alternative for L4-L5 Fusion
The best modern alternative for L4-L5 fusion is an innovative non-fusion device, such as the TOPS System. The TOPS System is a mechanical device made to be implanted between the L2 and L5 segments. It’s most often used for lumbar stenosis, degenerative spondylolisthesis, and joint arthrosis.
The TOPS System is the best modern alternative for L4-L5 fusion because it stabilizes the spine without eliminating the independent motion of the spinal segments. The device establishes a safe range of motion in the lumbar spine to preserve patients’ mobility. This is unlike spinal fusion, which eradicates the natural motion of the fused segments.

As an alternative to L4-L5 fusion, the TOPS System can also reduce the risk of adjacent segment disease (ASD). ASD is a potential complication of spinal fusion that occurs when the adjacent segments degenerate more rapidly due to the lack of movement in the fused segment.
In one study, TOPS was found to provide clinical improvement and radiologic stability in patients with spinal stenosis and degenerative spondylolisthesis after seven years.
