The spine supports the body and helps to stand, sit, bend, move, and spin. The spine, which protects the spinal cord from injury, extends from the base of the skull to lower end of the back. It is shaped like an “S”. It has 33 bones interconnected to each other.

These vertebrae are numbered and divided into four areas: cervical vertebrae (near the neck), thoracic vertebrae (upper back), lumbar vertebrae (lower back), sacrum (extreme lower back – connecting the spine to the hip), and also the tailbone coccyx of the spine. Only 24 of these bones move because the sacrum and tailbone are fused.

As the world is progressing fast we are observing technological progress in all areas of life. Spinal surgery has also shifted from primary incision / open surgery to minimally invasive microscopic spinal surgery, endoscopic surgery and keyhole surgery.

This modality, when carefully chosen for the right patient, ensures excellent results and a shorter hospital stay, along with shorter rest periods and quick return to work.

As the name suggests, this procedure is a very advanced form of spinal surgery that only requires tiny incisions, so there is only minimal damage to healthy tissue and thus faster recovery after surgery.

Minimally invasive spine surgery is performed using a particular surgical instrument called a tubular retractor. In certain situations, Special  Microlumbar retractors are used. Doctors insert these instruments through small incisions directly into the spine and tunnel-like opening to the area that needs to be treated. Tubular retractors keep the muscles open and hold throughout the procedure. It ensures that blood loss and damage to muscles, ligaments and bones are minimal compared to open surgery.

How Keyhole Spine Surgery Works?

Because the spinal cord and intervertebral nerve are located deep in the body, the spinal area to treat, muscle tissue must be removed out of the way to gain an approach for access to the spinal zone. These can be done by the use of small holes and directional instruments and tiny video cameras inserted through this minimal incision.

The incision resembles a keyhole and hence called a Keyhole procedure which is typically one inch long.

Minimally invasive spinal surgery is performed using a tiny incision. This small incision used to send segmental tubular retractors and dilator to pull the muscle away from the operating area and make the affected area of ​​the spine accessible. It minimizes damage to muscles and soft tissue and reduces blood loss during surgery.

An endoscope, a thin telescopic instrument with a video camera at the end, is inserted through a small hole to provide an image on the monitors of operating area in the operating room. Some surgeons use  Surgical microscope instead of the endoscope to achieve the same results. In these procedures, special mini surgical instruments sent through a working channel that functions to perform the surgery. After the procedure is complete, the tissue gets replaced after the removal of various instruments. The incision is then stitched and closed with sterile surgical gauze.
