Lamina is part of the bone that makes up a vertebra in the spine. Laminectomy is surgery to remove the lamina. Laminectomy is also performed to remove bone spurs in the spine. The procedure helps to reduce the pressure off the spinal nerves or spinal cord. Laminar spurs exerts pressure on the spinal nerves leading to painful legs, weakness or heaviness in buttocks and legs etc. leading to difficulty in mobility and movements in the patients. Patients also experience problems in emptying or controlling bladder and bowel. Symptoms worsen while standing or walking leading to poor quality of life and disability in patients. Post laminectomy, patients are hospitalised for one to three days, and the individual patient's return to normal activity is largely dependent on his/her pre-operative condition and age. Patients are encouraged to walk directly following a laminectomy for lumbar stenosis.
In laminectomy lamina (part of the bone that forms the vertebral arch in the spine) is removed which is putting pressure on the spinal cord leading to back pain, numbness in legs, difficulty in walking etc. This is the result of spinal stenosis and the surgical inventions are towards removing the stenosis of the spine to relieve the pain. A laminectomy is performed under anesthesia. Patient is administered either a general anesthesia or spinal anesthesia. An anesthesiologist continuously monitors the patient you throughout the surgery. The surgical approach is based on requirements for patient based on the severity of the disease. The incision is either through back or neck. The part of lamina bone is reached with the help of radio-imaging techniques with minimal incision. . The removal is either in parts or the entire lamina bone is removed depending upon the need of the surgery for the patients. The incisions are sutured and closed with sterile bandages for preventing infection and healing.
The success rate of a lumbar laminectomy to alleviate pain from spinal stenosis is generally favourable. Following a laminectomy, approximately 70% to 80% of patients will have significant improvement in their function (ability to perform normal daily activities)
Like any other surgery, the patient must be stable in all other physiological parameters. The concomitant diseases such a diabetes mellitus, hypertension must be under control. The patient must informed in advance for any allergies, past medical history, details of consumption of prescription and non-prescription medicines to the doctor in advance. Alcohol and nicotine are not good for health and for bone health they are like poison. Their consumption must be stopped before and after surgery including the recovery phase.Post-surgery, all the necessary advice in terms of medicine, diet, physical exercise must be followed. Pain, bleeding, swelling are expected after the surgery. Appropriate medications shall be provide for relief
When is lumbar laminectomy recommended?
The main reason for this operation is the intolerable pain. For severe pain and disability surgery is the treatment option. However, advanced age is one of the deterrents for this procedure.
Are laminectomy surgeries successful?
Laminectomy surgeries have good outcomes with most patients getting pain relief of their leg pain and are able to perform daily activities.
How long will patient be in the hospital?
Laminectomy patients can usually be out of bed several hours after the operation. The majority of patients go home 48 to 72hours after surgery. In few instances patients can be discharged after 24 hours.
What medicines I shall receive after the procedure?
Pain-relieving medicines are the mainstay of the post-operative therapy apart from the anti-infective and dressings to prevent any infection.
Does spinal anaesthesia cause harm to the spinal cord?
No; spinal anaesthesia is injected with a specialised needle which causes least of the piercing which heals quickly and is almost painless. the dose of anaesthetic agent required is also smaller compared to the general anaesthesia and patient recovers faster from the sleep induced by this procedure
Brain tumors are abnormal growth or cancers within the brain. Earlier having a brain tumor meant awaiting certain death.
Spine surgery is traditionally done as "open surgery," meaning the area being operated on is opened with a long incision to allow the surgeon to view and access the anatomy. In recent years, however, technological advances have allowed more spine conditions to be treated with a minimally invasive surgical technique.
Endoscopic Spine Surgery is a type of state-of-the-art surgery that uses small tubular system or micro incisions, assisted with an endoscope or microscope. This type of surgery provides patients with quicker recovery and less pain than traditional spine surgery. It preserves normal spine mobility because the spine is not fused with screws and rods.
Surgery for skull base tumours results in a cure for many patients. For most of these patients, traditional open craniofacial surgery is the safest approach with the best chance of success. In recent years, however, endoscopy-assisted surgery, which leaves no visible scars, has been found to be effective for the resection of some skull base tumours.
An Arterio-Venous Malformations (AVM) is a tangle of abnormal and poorly formed blood vessels (arteries and veins), with an innate propensity to bleed. An AVM can occur anywhere in the body, but brain and spinal AVMs present substantial risks when they bleed.
A cranioplasty is performed to correct a deformity or defect of the skull. The deformity/defect could be congenital, as a result of trauma or acquired for example after a previous surgery involving the skull. A craniotomy is the most commonly performed surgery for brain tumour removal.
A stereotactic brain surgery is a surgical procedure where lesion, frequently a brain tumour, is removed with assistance of image guidance, that is previously obtained images (usually an MRI) are used to guide the surgeon to the exact location of the lesion to facilitate as accurate a pathway through the brain and safe removal of as much abnormal tissue as pos
Lumbar fusion (Arthrodesis) is a major surgery performed to permanently join together two or more bones in the spine so there is no movement between them. These bones are called vertebrae. A lumbar fusion surgery is designed to stop the motion at a painful vertebral segment, which in turn should decrease pain generated from the joint.
Microdiscectomy, also called Microlumbar Discectomy (MLD), is performed for patients with a painful lumbar herniated disc. Microdiscectomy is a very common, if not the most common, surgery performed by spine surgeons. The operation consists of
Lumbar decompression surgery is a type of spinal surgery performed to treat some conditions affecting the lower back (lumbar spine) that haven't responded to other treatments. The main aim of this type of surgery is to improve problems affecting the legs, such as persistent pain and numbness, caused by pressure on the nerves in the spine.
Aneurysm repair is a surgical procedure to correct an aneurysm, a weak area in a blood vessel wall that causes the blood vessel to bulge or balloon out and sometimes burst (rupture). It may cause:-Bleeding into an area around the brain, heart, abdomen-Bleeding that forms a collection of blood (hematoma)
Most patients with neurological disorders are first examined by neurologist who has specialized training in the diagnosis and non-surgical treatment of a wide variety of diseases affecting the brain, spinal cord, nerves and muscles.
Spinal stenosis is a narrowing of the spinal canal, which places pressure on the spinal cord. If the stenosis is located on the lower part of the spinal cord it is lumbar spinal stenosis. Stenosis in the upper part of the spinal cord is cervical spinal stenosis.
Brain surgery is an operation to treat problems in the brain and surrounding structures. Brain surgery may be necessary for patients with a range of neurological ailments. Two of the most common reasons patients require brain surgery are brain tumours and brain trauma. The surgeon makes a surgical cut through the scalp.
Neck pain may be caused by disc degeneration, narrowing of the spinal canal, arthritis, and, in rare cases, cancer or meningitis. There are times when surgery is the best option for treating the medical condition responsible for the neck pain.
Almost everyone will experience back pain at some point in their lives. This pain can vary from mild to severe. It can be short-lived or long-lasting. However it happens, back pain can make many everyday activities difficult to do.
Surgical intervention is the primary treatment for brain cancers (tumours). Such procedures are intricate and need specialised techniques to remove the tumours without causing severe damage. Many benign (non-cancerous) tumours are treated only by surgery.
Spinal cord is a bundle of nerves that runs down the middle of the back. It carries signals back and forth between the body and the brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures or dislocates the vertebrae, the bone disks that make up the spine.
