Micro-discectomy Advice SheetThis is an example of information/advice about this condition and procedure. You should always take detailed advice from your surgeon and physiotherapist. You have been scheduled for a procedure called a lumbar micro-discectomy. This is one of the commonest operations performed on the low back. The lumbar discs are the joints at the front of the spine that give the spine its flexibility. micro-discectomy is a very successful operation aimed at relieving leg pain associated with nerve compression problems. It is not an operation to cure low back pain. You will have had an MRI scan which confirms that there is a degree of compression upon one of the nerves in your lower back caused by a herniation (disc material extending outside its normal confines) in one of the discs. Usually, you will be suffering with pain down one of your legs. micro-discectomy is a very successful operation aimed at relieving leg pain associated with nerve compression problems. It is not an operation to cure low back pain. The operation is performed through a small incision at the base of the spine. During the surgery, the disc material pressing on the nerve is removed. The reasons for micro-discectomy surgeryUsually patients for micro-discectomy have severe leg pain often extending the full length of the leg in the territory supplied by the nerve root. An MRI scan will have confirmed nerve compression in the low back. The vast majority of patients with disc prolapse do not need an operation and many will get better with either conservative treatment such as physiotherapy, with medication, or with the passage of time. The reason you are undergoing an operation is because your symptoms are still significantly troubling you and have failed to respond to non-surgical treatment. It is a joint decision taken between the Surgeon and the patient when it is decided that the potential rewards of an operation exceed the possible small risks of complications. The rewards of disc surgeryThe main anticipated outcome after micro-discectomy surgery is relief of your leg pain. The success rate varies. We believe that it is reasonable to say that 80 – 90 % of patients who have a micro-discectomy are satisfied with the relief of leg pain that they achieve. Patients who have tingling in the leg associated with nerve compression, find in many cases that this tingling settles down. It is difficult to predict if symptoms of numbness or weakness will improve. Any recovery may take up to two years to occur from the time of surgery, and recovery is not guaranteed. If two years after the operation your foot remains numb and weak, it is likely to remain numb and weak forever. Please remember that discectomy is not an operation for the relief of back pain. The risks of micro-discectomy surgeryThe vast majority of micro-discectomy operations pass off with no problems. There are however, some small risks associated with any operation. Whilst the chances of these happening is quite small, it is important that you understand that potential problems can occur. Potential risks include:
Time scalesYou will usually be in Hospital for 48 hours after a micro-discectomy. You will be able to go home walking independently. You will return to the Hospital at approximately 6 – 8 weeks after the operation for a quick check up and provided everything has gone satisfactorily, you may well be discharged at this time. Return to normal function after spinal surgeryPatients are walking within 24 hours of their surgery. The time taken to return to work varies between patients. If you work from home doing office type work, you will probably be working within a few days. Light manual workers will usually return to work at four weeks. Patients who do heavy physical manual work may not return to work for some 6 – 12 weeks after the surgery and in particular this group of patients will often need a course of physiotherapy to help strengthen the muscles around the spine. Provided that the wound has healed satisfactorily, we are happy for patient’s to return to activities such as swimming at about four weeks after surgery and also cycling. We do not usually recommend a return to contact sports such as football for at least 12 weeks after the operation. If you are planning to return to this level of sport, you may need a course of physiotherapy to help strengthen the spine before returning to such activity. You will be able to drive a car four weeks after your operation. You can resume normal sexual activity 4 weeks after surgery. A summary of micro-discectomy surgerymicro-discectomy is a successful operation for relieving leg pain. The results of surgery cannot be guaranteed. A decision to proceed with surgery is one taken jointly by yourself and by your Surgeon. The vast majority of operations are highly successful. There are some small risks associated with the surgery and if these occur, they can be significant.
