Like some of my clients, I sustained a work related back injury resulting in the need for surgery. In Part II of Exploring Back Surgery, I will discuss the procedure I underwent to repair a large free fragment disc herniation in my back.
A discectomy is a surgery done to remove a herniated disc from the spinal canal. When a disc herniation occurs, a fragment of the normal spinal disc is dislodged. This fragment may press against the spinal cord or the nerves that surround the spinal cord. This pressure causes the symptoms that are characteristic of herniated discs.
The surgical treatment of a herniated disc is to remove the fragment of spinal disc that is causing the pressure on the nerve. This procedure is called a discectomy. The traditional surgery is called an open discectomy. An open discectomy is a procedure where the surgeon uses a small incision and looks at the actual herniated disc in order to remove the disc and relieve the pressure on the nerve.
How is a discectomy performed?
A discectomy is performed under general anesthesia. The procedure takes about an hour, depending on the extent of the disc herniation, the size of the patient, and other factors. A discectomy is done with the patient lying face down, and the back pointing upwards.
In order to remove the fragment of herniated disc, your surgeon will make an incision over the center of your back. The incision is usually about 3 centimeters in length. Your surgeon then carefully dissects the muscles away from the bone of your spine. Using special instruments, your surgeon removes a small amount of bone and ligament from the back of the spine. This part of the procedure is called a laminotomy.
Once this bone and ligament is removed, your surgeon can see, and protect, the spinal nerves. Once the disc herniation is found, the herniated disc fragment is removed. Depending on the appearance and the condition of the remaining disc, more disc fragments may be removed in hopes of avoiding another fragment of disc from herniating in the future. Once the disc has been cleaned out from the area around the nerves, the incision is closed and a bandage is applied.
What is the recovery from a discectomy?
Patients often awaken from surgery with complete resolution of their leg pain; however, it is not unusual for these symptoms to take several weeks to slowly dissipate. Pain around the incision is common, but usually well controlled with oral pain medications. Patients often spend one night in the hospital, but are usually then discharged the following day. A lumbar corset brace may help with some symptoms of pain, but is not necessary in all cases.
What is endoscopic microdiscectomy?
This is a newer technique utilized by my surgeon. This technique may allow your surgeon to perform a procedure called an endoscopic discectomy. In an endoscopic discectomy your surgeon uses special instruments and a camera to remove the herniated disc through very small incisions.
The endoscopic microdiscectomy is a procedure that accomplishes the same goal as a traditional open discectomy, removing the herniated disc, but uses a smaller incision. Instead of actually looking at the herniated disc fragment and removing it, your surgeon uses a small camera to find the fragment and special instruments to remove it. The procedure may not require general anesthesia, and is done through a smaller incision with less tissue dissection. Your surgeon uses x-ray and the camera to "see" where the disc herniation is, and special instruments to remove the fragment.
