Minimally Invasive Spine Surgery (MIS) includes posterior cervical fusion, thoracolumbar fusion, diskectomy, laminectomy,
X–stop, vertebroplasty and kyphoplasty. With the advance of MIS technology, MIS can now be performed for spinal deformity correction involving multiple levels, like degenerative scoliosis. The MIS technique employs the use of tubular retractors/ endoscopes to achieve the necessary exposure for the surgical site. MIS minimizes tissue retraction and dissection. The incisions are much smaller than the traditional open approach. Patients usually suffer from less blood loss, less postoperative muscle spasms, pain and scarring. Patients typically have a much faster functional recovery.
Endovascular intervention for Cerebral Aneurysm – While the traditional method is to clip the aneurysms, most of the aneurysms can now be fully treated by coiling, with or without stenting. Angiogram is first performed, which involves the passing of a catheter from the patient's femoral artery in the groin up to the vessels leading to the brain. Contrast dye is then injected to delineate the anatomy of the aneurysms. Then, platinum coils are placed into the aneurysms to induce clotting. Sometimes, a stent is inserted as part of the procedure to maintain patency of the normal vessel and to stabilize the coils in a broad-based aneurysm. This procedure has proved to have lower mortality, morbidity, shorter length of stay and blood loss, when compared to the traditional approach.
Laser-assisted Tumor Removal is the latest technology used in the resection of tumors of the brain, spinal cord and skull base. Carbon Dioxide laser is transmitted via fiberoptics to aid in tumor removal. Traditional techniques using microdissection and CUSA (Cavitronic Ultrasonic Suction Aspiration) can be ineffective at times in dense, fibrous, calcified tumors. This is especially true in large vascular tumors where traditional techniques are associated with significant blood loss. The use of laser has increased the precision of the resection, improves access to the tumor, decreasing blood loss and surgical time.
Stereotactic Radiosurgery (SRS) employs 3-dimensional reference system to localize a target lesion, usually a tumor, and deliver a highly focused ionizing beam of irradiation to the target. Information from MRI/CT is transferred directly into the treatment planning computer to create a 3D model of the tumor and the surrounding tissue. SRS is an intense form of radiation therapy. It is generally used for tumors inaccessible or unsuitable for open surgery.
Artificial Disc Replacement Surgery refers to the replacement of the degenerative discs with metallic disc implants. The disc implants allows movement between the adjacent spinal vertebral bodies, allowing more flexibility and minimizing accelerated degeneration of the adjacent levels. The artificial disc replacement is generally done on younger patients. The procedure is done through a small incision on the abdomen. Patients generally show a faster recovery than the traditional open procedures.
