Hemilaminectomy is a surgical procedure during which part of the vertebral arch is removed. Unlike a laminectomy, in which the entire spinal process is removed, a hemilaminectomy involves the removal of only half of the arch.
Indications for hemilaminectomy:
– herniated intervertebral discs, which is accompanied by compression of the nerve roots;
– spondylolisthesis;
– spinal deformity due to fracture or injury;
– spinal canal stenosis;
– malignant neoplasms.
Hemilaminectomy is performed under general anesthesia. During the operation, the surgeon makes an incision in the skin, then cuts through the muscles and fascia to gain access to the spine. After this, part of the vertebral arch is removed, freeing the compressed nerve roots. The removed bone fragment is placed in a special container, which is then sent for histological examination.
After the operation, the patient is transferred to the intensive care unit, where he is under the supervision of doctors until full recovery. The rehabilitation period after hemilaminectomy can take from several days to several weeks, depending on the severity of the injury and the patient’s condition.
In general, hemilaminectomy is an effective treatment for many spinal diseases, but it should only be performed when indicated and under the supervision of an experienced surgeon.
Hemilaminetomy is a surgical operation that involves removing half of the lamina - the plate of the spinal arch. This dissection is often used for osteochondrosis of the cervical and lumbar spine (spondylosis, pseudarthrosis).
A hemilaminectomy is often called both a half discectomy (if the entire hemiplate is removed rather than just one half) and a hemidiscectomy. Hemilaminotomy can be performed symmetrically at two levels simultaneously. Or it can be done asymmetrically on one level. Here, the symmetry of the process is not determined by the anatomical division of the spinal cord into two hemifields, as is commonly believed, but by the position of the plates of the hemiposition arcs for a particular disc.
When pain occurs, it is associated with nerve root injury syndrome. At the same time, the vertebra itself, the lamina to which the hemilaminectomy was performed, is intact. In this case, degenerative changes begin in the intervertebral disc, the plate becomes deformed and becomes less durable. And a rupture occurs in the hernial protrusion of the nucleus pulposus into the body.
In the clinic, these problems are solved by performing hemilaminectomy or semi-discectomy and vertebroplasty
The resulting effect is the excision of half of the pancreas
