Spinal Stenosis Surgery: Hospital Stay Or Outpatient Procedure?

Spinal stenosis is a condition that causes spaces in the spine to become narrow, which can put pressure on the spinal cord and nearby nerves. While surgery is not always necessary, it may be required to stabilize the spine and prevent further damage if other treatments are ineffective. The length of a hospital stay following spinal stenosis surgery depends on the type of surgery performed and the patient's recovery, typically ranging from one to two days.

Recovery time: 2-3 months until all regular activities can be resumed

Spinal stenosis is a condition that causes the spaces in the spine to become narrow, which can put pressure on the spinal cord and nearby nerve tissue. This can result in pain and numbness in the neck, back, arms, legs, hands, or feet. While surgery is an option for treating spinal stenosis, it is usually only considered if other treatments have not been effective in managing symptoms.

The recovery time after spinal stenosis surgery can vary, but it typically takes around 2-3 months for a person to resume all their regular activities. In the initial stages of recovery, patients are provided with pain medication and are encouraged to start walking as soon as they are able to. They may also be advised to wear a brace or corset to support their back.

During the first few days or weeks after the procedure, most people can return to desk jobs. However, for those engaged in physical labor, it may take up to 8 weeks to get back to work. It is recommended to consult a doctor and schedule follow-up appointments to monitor the healing process through imaging tests such as X-rays or CT scans.

To aid in recovery, patients may require physical therapy to strengthen their back and perform exercises that help build and maintain spinal stability. The goal is to make the spine more stable and provide better support for the back. In some cases, older individuals may need to spend time in a rehabilitation facility before returning home.

Risks: nerve damage, tissue tears, chronic pain, and trouble passing urine

Spinal stenosis surgery is usually recommended when non-surgical methods like medication, therapy, and exercises have failed to alleviate symptoms. The decision to proceed with surgery is made after a detailed discussion between the doctor and the patient.

Spinal stenosis surgery carries several risks, including nerve damage, tissue tears, chronic pain, and trouble passing urine.

Nerve damage is a potential risk of spinal stenosis surgery due to the proximity of the spinal cord and nerves. Surgeons take great care to avoid damaging nearby nerves during the procedure. However, in rare cases, nerve damage can occur, leading to potential long-term complications.

Tissue tears can happen during the surgery as well. The spinal region contains many soft tissues, and despite the surgeon's expertise, accidental tears can occur. This may lead to additional pain and a prolonged recovery period.

Chronic pain is another potential complication of spinal stenosis surgery. While the surgery aims to alleviate pain, in some cases, patients may continue to experience pain after the procedure. This could be due to various factors, such as the severity of the condition, the patient's overall health, and the success of the surgery.

Some patients may also experience difficulty passing urine after spinal stenosis surgery. This is often related to bladder dysfunction caused by nerve compression or damage. In a study of 20 patients who underwent decompressive laminectomy for severe lumbar stenosis, 45% showed improvement in post-voiding residual urine volume, 40% remained unchanged, and 60% reported subjective improvement in bladder function at the 6-month follow-up.

Pre-surgery: exercise, stop smoking, and review medications

Spinal stenosis surgery may require a hospital stay, and doctors recommend certain preparatory steps before the procedure. These include exercising, stopping smoking, and reviewing medications.

Pre-Surgery Exercise

Exercise before spinal stenosis surgery is recommended by doctors to help patients recover faster. The focus of pre-surgery exercise is to improve spinal flexibility, strengthen the muscles of the trunk and lower extremities, and improve overall conditioning to enhance spinal function and relieve pressure on spinal nerves.

There are three recommended types of exercises: lumbar flexion exercises, core strengthening exercises, and aerobic exercises. Swimming is also an excellent option as the buoyancy of the water reduces pressure on the spine. It is important to start slowly and gradually increase the intensity and duration of exercises. Before starting an exercise program, it is crucial to consult with a healthcare provider or physical therapist to ensure the exercises are safe and appropriate for your age and condition.

Stop Smoking

Smoking negatively affects the outcomes of spinal surgery. Nicotine is a central pain-modulating agent, and individuals with higher rates and intensity of spine-related pain may be predisposed to addiction to help mitigate their symptoms. Additionally, the higher incidence of depression among smokers can lead to increased back-related disability, negatively impacting postoperative outcomes. Therefore, smoking cessation is recommended before surgery to potentially mitigate these unwanted outcomes.

Review Medications

Before spinal stenosis surgery, it is essential to review all medications and supplements with your doctor. Certain medications may react with the anesthesia used during the procedure, so it is crucial to discontinue any substances that may cause interactions.

Post-surgery: pain medication, brace or corset, and physical therapy

Spinal stenosis surgery is usually performed on an elective basis, if pain and symptoms persist after trying other treatments, such as physical therapy and medication. The most common type of surgery for spinal stenosis is laminectomy, where the surgeon removes the bone, spurs, and ligaments that are pressing on the nerves. The recovery process after spinal stenosis surgery can be tough and grueling, but with proper post-operative care, one can make a full recovery.

Pain Medication

Doctors may prescribe pain medications, such as Duloxetine, Gabapentin, and Pregabalin, to help manage post-surgical pain. Epidural injections of corticosteroids can also be administered to reduce inflammation and pain. Nerve blocks are another option, where anesthetics are injected near the damaged nerves to provide relief.

Brace or Corset

Using a brace or corset can be beneficial in easing post-operative back pain. A spinal stenosis back brace, for instance, helps take the pressure off the lumbar region by shifting the load to the abdominal area. Bracing can also help prevent unnecessary movement that could hinder the recovery process.

Physical Therapy

Physical therapy is an essential part of the treatment plan following spinal stenosis surgery. Aquatic physical therapy, in particular, can help relieve pressure exerted on the spine due to buoyancy, improve blood flow to surrounding muscles and joints, and increase flexibility. Physical therapists can also recommend specific exercises to strengthen the lower back muscles and restore mobility, such as bends, pelvic tilts, and standing squats. It is important to start slowly with physical activity and consult with a doctor or physical therapist.

Surgery types: laminectomy, laminotomy, foraminotomy, discectomy, spinal fusion

Spinal stenosis surgery is often performed as an outpatient procedure, meaning the patient can return home on the same day. However, in some cases, a short hospital stay of one to two nights may be required for observation and recovery.

Now, here's an overview of the different types of spinal surgery:

Laminectomy

Laminectomy is a common surgical procedure to decompress the spinal canal and relieve pressure on the spinal nerves. It involves removing the lamina, which is the back part of each vertebra that covers the spinal canal. This surgery is often performed for conditions like spinal stenosis, especially in middle-aged and elderly patients. It is also indicated for other conditions such as degenerative stenosis, fractures, spinal tumours, abscesses, and deformities.

Laminotomy

Laminotomy is a less invasive alternative to laminectomy. During this procedure, the surgeon makes a small hole in the lamina and removes a tiny piece of bone to relieve pressure on the spinal cord or nerves. Laminotomy is favoured by some doctors as it requires a smaller incision and causes less damage to the surrounding muscles.

Foraminotomy

Foraminotomy is a surgical procedure that enlarges the area around the vertebrae in the spinal column, relieving pressure on compressed nerves. This surgery is performed to address symptoms such as pain, tingling in the arms and legs, and weakness caused by compressed nerves.

Discectomy

Discectomy is a type of surgery performed to fix a bulging or herniated disc in the lower back. During this procedure, a surgeon removes part of the damaged disc to ease the pressure on the nerve root or spinal cord. Minimally invasive discectomy uses smaller incisions and removes minimal bone or muscle tissue. This surgery is recommended when other treatments, such as physical therapy and anti-inflammatory medications, have not provided relief.

Spinal Fusion

Spinal fusion techniques are employed when stenosis is associated with spinal instability, degenerative conditions, or deformities such as kyphosis or scoliosis. Fusion is often combined with laminectomy to prevent an increased risk of spinal instability.
