LAMINECTOMY BACK SURGERY MIS
What is laminectomy back surgery MIS (lumbar lsminectomy and cervical laminectomy)?
Laminectomy back surgery MIS (lumbar laminectomy and cervical laminectomy) is the surgical procedure in which a part of the bone is removed at the back of the vertebra (petal) to create a space.
So that the spinal cord or the nerves in the spinal canal are not pressed. This pressure is usually caused by hyperplasia of the bone (osteophyte) that develops in the vertebral tube and may involve any part of the spine, but it is more common in the lumbar and cervical spine.
Laminectomy back surgery MIS (lumbar laminectomy and cervical laminectomy) is an operation that occurs when conservative therapies such as medication, physiotherapy fail and the symptoms do not go away.
Laminectomy back surgery MIS may also be recommended when the symptoms are very severe or there is dramatic deterioration.
When is a laminectomy back surgery MIS recommended?
The development of osteophytes within the spinal canal can reduce the space available in the spinal cord and the nerves. This pressure can cause pain, weakness or numbness that can spread to the hands or feet.
Your doctor may recommend a laminectomy back surgery MIS if:
- Conservative treatment, such as medication or physiotherapy, has failed to improve the symptoms.
- There is muscle weakness or numbness in the upright position or inability to walk.
- When there is loss of control of urine or stools.
- In some rare cases, laminectomy may be necessary as part of the surgery to treat a herniated disc. Your surgeon may need to remove part of the back of the vertebra (petal) to access the damaged disc.
How is a laminectomy back surgery MIS done?
Laminectomy back surgery MIS is performed under general anesthesia.
The incision is performed after a radioscopic confirmation of the suffering level. The muscles of the area are detached to reveal the lamina of the vertebrae that suffers. With special mini-tools the bone that presses the spinal cord or nerve roots is removed and, depending on the findings concerning each individual patient, it is supplemented with the corresponding nerve decompression.
If the lamine is performed for intervertebral disc herniation, then the surgeon apart from the bone also removes the fragments of the damaged disc.
If there is also a displacement of vertebrae, it may additionaly be necessary to stabilize the vertebrae between them and some form of fusion.
The procedure is presently performed with minimally invasive surgery using a microscope or an endoscope.
What are the possible complications of a laminectomy back surgery MIS?
Laminectomy back surgery MIS is generally a safe procedure. Nevertheless, as is the case with every surgery it has some dangers.
The possible complications of a laminectomy back surgery MIS are:
- Bleeding.
- Infection.
- Deep vein thrombosis.
- Injury of nervous tissue.
- Damage to the Dura Mater and cerebrospinal fluid outflow.
However, all measures are being taken to avoid these complications, and thanks to the new pharmaceutical protocols and newer microsurgical techniques (minimally invasive surgery MIS / minimally invasive spine surgery MISS) with the help of the microscope and endoscopes, these complications occur in less than 0.5% of cases.
What is the duration of hospitalization after a laminectomy back surgery MIS?
Usually the patient after a laminectomy back surgery MIS is mobilized on the same night of the laminectomy procedure and stays in the hospital for 24-48 hours depending on the age and the associated medical problems.
He can return to his activities usually within two weeks, depending of course on the preoperative neurological condition.
Neurological improvement is usually immediate and spectacular, but in severe cases empowerment physiotherapy is also recommended.
