The goal of minimally invasive spine surgery is to stabilize vertebral bones and spinal joints and relieve pressure that is applied to spinal nerves. Such condition occurs due to the issue of spinal instability, herniated discs, bone spurs, scoliosis or spinal tumors.
The most advance and latest technology, minimally invasive spine surgery means a smaller incisions, smaller scars, reduced blood loss and shorter accommodation at hospital. In a contrary to open spine surgery, invasive surgery treatment option offers faster, safer and less recovery time. As compare to open spine surgery, it provide reduced trauma to the muscles and soft tissues.
Benefits of minimal invasive spine surgery
Open spine surgery might be a good option in different individual cases, minimal invasive surgery provide you an appropriate and best option. The benefits include:
- Smaller skin incisions (sometime as small as 2 cm) or scars
- Lesser blood loss during surgery
- Quick recovery time
- Lesser amount of pain medication needed during hospital stay
- Since it involves less or no cutting of muscles as a result there is reduced risk of muscles damage.
- Shorter stay at hospital and lesser rehabilitation period
Condition that can be treated using minimally invasive surgery (MIS) surgery
- Degenerated disc diseases
- Lumbar spinal stenosis
- Herniated discs
- Spinal tumors
- Vertebral compression fractures
- Spinal instability
- Spinal infection
- Scoliosis (spinal deformity)
How minimally invasive surgery (MIS) is performed?
The MIS surgery can be percutaneous which is done through the skin, or mini-open which is performed by operating through a small incision. During the procedure, a small incision is made and the tubular retractor is inserted that create al tunnel to the small area where the issue is located in the spine. The tubular retractor holds and keeps the muscles open during the whole procedure.
The surgeon uses small instruments that easily fit through the center of the tubular retractor. Any other essential devices such as rods and screws are inserted through the retractor as well as any bone or disk material that is removed, brings out through the retractor. The surgeon is escorted by fluoroscopy, the method that helps the doctor where to place the incision and insert the retractor. This method display the real time X-rays images of the patients spine on the monitor throughout the whole surgery. In order to magnify the view through the retractor, the surgeon may use an operating microscope as well.
Post treatment precaution
The surgeon may recommend particular exercise as a part of the post-surgery precaution plan. All such action like lifting heavy weight or action that put extra pressure on spine is avoided as long as it is recommended by the doctor.
Risk associated with MIS
The potential risk associated with the surgery may comprise blood clots, anesthesia complications, allergic reaction and some adverse affect. In the absence of undiagnosed medical problem such as heart disease can increase the complication. In addition to it, injury to nerves and blood vessels may also occur.
