Important Instructions After Surgery for a Herniated Disc
The following section focuses specifically on recovery after surgery for a herniated lumbar disc.
After surgery for a herniated disc, it is important to protect your spine during the early healing period and to avoid movements or activities that place excessive load on the lumbar discs. The aim is to allow the operated disc and surrounding tissues to heal while reducing the risk of recurrent disc herniation.
Protecting Your Spine
Maintain good posture and keep your back in a neutral position. Avoid unnecessary lumbar flexion (bending forward) and avoid prolonged periods of sitting.
During the early postoperative period:
- Avoid sitting continuously for more than approximately 30 minutes.
- Where appropriate for your operation and your surgeon’s instructions, spend more time lying down or standing and walking upright rather than sitting for prolonged periods, particularly during the first few weeks.
- When sitting, keep your back straight and use appropriate lumbar or back support.
- When getting up from a chair, avoid bending forward excessively. Keep your spine relatively straight and use your legs and arms to assist you.
- Avoid unnecessary bending, lifting, twisting, or other activities that place substantial load on the lumbar spine.
- When coughing or sneezing, brace your trunk and avoid suddenly lurching or bending forward.
Sudden forward bending, particularly when combined with straining, coughing, sneezing, or lifting, can increase pressure within the lumbar discs. Avoiding these movements helps protect the operated area during the early healing period.
When picking up something from a low surface or the floor, avoid bending forward from your back. Keep your back as straight as you comfortably can, and lower yourself by bending your hips and knees. If needed, hold on to a stable piece of furniture for support. This helps reduce strain on your lower back.
The First Six Weeks
During the first six weeks after surgery, the operated disc is still healing. In particular, the annulus fibrosus, the tough outer layer of the disc, has not yet fully healed. The softer material within the disc, known as the nucleus pulposus, may therefore remain vulnerable to re-herniation through the healing annular defect.
For this reason, careful spine protection is particularly important during this early postoperative period. Maintain good posture, avoid unnecessary bending forward, and avoid activities that markedly increase pressure within the disc.
These precautions are intended to protect the healing annulus while it repairs and to reduce the risk of recurrent disc herniation.
The precise restrictions on sitting, lying, standing, bending, lifting, exercise, and other activities depend on the operation performed and the individual patient. Your surgeon’s specific postoperative instructions should take precedence.
Wound Care
Breathable dressings such as Primapore and Mepore allow moisture vapour to escape. Follow your surgical team’s instructions about showering and dressing changes. If the dressing becomes wet, loose or soiled, follow the replacement instructions provided for that product.
Warning Signs After Lumbar Disc Surgery for a Herniated Disc
New or Returning Leg Pain, Numbness, or Weakness
During surgery for a herniated lumbar disc, the part of the disc pressing on the nerve is removed to take the pressure off.
After surgery, new or returning pain that travels from the buttock down the thigh, calf, leg, or foot, especially with new numbness or weakness, is a red flag. This can mean the nerve is being pressed again, either from another piece of disc herniating or from bleeding that forms a clot and presses on the nerve.
If pain, numbness, or weakness newly appear or get worse after initial improvement, contact your spine specialist urgently.
Increasing Wound Pain, Redness, Discharge, or Fever
Increasing pain, redness, swelling, or tenderness around the wound, or any new fluid or pus coming from the incision can be a sign of wound infection.
A bad smell, fever, or feeling generally unwell can also be warning signs.
If any of these happen, contact your spine specialist promptly for assessment.
Clear Fluid or Swelling Around the Wound
Clear, watery fluid leaking from the wound, or a new soft swelling or tense lump under the skin near the incision, especially in the first few weeks, may suggest a cerebrospinal fluid leak.
This happens when the thin lining that surrounds the nerves, called the dura, has a small tear and fluid escapes.
If you notice clear fluid or a new swelling around the surgical site, contact your spine specialist promptly for assessment.
Warning Signs After Lumbar Spinal Surgery for Spinal Fusion
You have undergone lumbar spinal fusion surgery, where your surgeon used spinal implants, such as screws and rods, to stabilize your spine while the bones heal and fuse together.
A bone graft is placed around or between the bones to help with this.
After surgery, there are important warning signs to watch for while the wound and fusion are healing.
Sudden New Back or Leg Pain
Sudden new or worsening back pain after surgery, especially if it is much worse on one side, or new pain that travels down the leg, can be a warning sign of a problem with the implants.
This might happen if an implant loosens or shifts from its intended position, and the discomfort is often worse with bending, twisting, standing up, or changing positions.
If you develop sudden or severe new back or leg pain after fusion surgery, contact your spine specialist promptly for assessment.
Persistent Leg Pain, Numbness, or Weakness
New or gradually worsening pain, numbness, or weakness in one or both legs after surgery may be a warning sign of bleeding near the surgical site.
Sometimes blood can collect and form a clot that presses on the nerves. This pain is often steady and persistent, rather than clearly linked to movement.
If you notice new or worsening leg pain, numbness, or weakness after surgery, contact your spine specialist urgently for assessment.
Increasing Wound Pain, Redness, or Discharge
Increasing pain, redness, or swelling around the wound, especially with pus, a bad-smelling discharge, persistent fluid leakage, or fever, can be signs of a wound infection.
A steady, dull ache at the surgical site or a dressing that keeps getting soaked with fluid are also warning signs.
If you notice these symptoms after surgery, contact your spine specialist promptly for assessment.
Swelling and Pain in One Leg
New swelling, tightness, or pain in one leg, especially if that leg becomes noticeably larger than the other, can be a warning sign of a blood clot in a deep vein, called a DVT.
DVT risk can increase after surgery due to reduced mobility.
If you notice new or increasing swelling, tightness, or pain in one leg after surgery, seek urgent medical assessment.
This can happen if there is a small tear in the dura, the protective lining around the nerves, allowing fluid to collect under the skin or leak through the wound.
If you notice a new swelling or clear fluid from the wound after surgery, contact your spine specialist promptly for assessment.
Frequently asked questions
How often do these complications require repeat surgery?
Most complications do not require another operation. Symptoms may be caused by temporary inflammation or swelling and can often be managed with closer monitoring, medication, rest, or changes in activity. Your surgeon will advise if further treatment is needed.
How do I know if my symptoms are part of normal recovery?
Some pain, stiffness, and discomfort can be expected after surgery and should gradually improve. Contact your surgeon if symptoms are new, worsening, unusually severe, or causing concern. Your surgeon can assess whether you need closer monitoring or further treatment.
