This revolutionary surgical guidance system is transforming spine surgery from freehand procedures to highly accurate, state-of-the-art procedures.
Mazor Robotics’ Renaissance™ is a specially-designed surgical guidance system that allows surgeons to perform safer and more accurate spine surgeries. For patients, this means better clinical outcomes with less pain, fewer complications and shorter recovery time. Renaissance is in daily use in leading hospitals with thousands of successful cases worldwide.
Patients suffering from debilitating back pain or limited range of motion caused by spinal deformities and degenerative conditions such as slipped vertebrae, scoliosis, spinal nerve impingement (pinched nerves) and those in need of spinal biopsy can benefit greatly from the Mazor Renaissance. Read below for some spinal surgery options and how it may help you.
What is Spinal Fusion?
It is the process of fusing two or more vertebrae together, immobilizing them to create a single continuous bone. It is used to treat broken vertebra, spinal deformity, spinal weakness, spinal instability or chronic low back pain.
Our surgeons use a bone graft in conjunction with the body's natural bone growth processes so that bone growth can occur. This bone graft may be in a pre-formed shape or contained in a cage made out of plastic, carbon fiber or metal. Our surgeons often use implanted plates, screws or robs to hold the vertebrae and graft together to promote healing. Once this bone graft heals, the vertebrae are permanently fused.
What type of surgery is needed for spinal fusion?
Minimally invasive surgery (MIS) uses smaller incisions and usually results in less postoperative pain and faster recovery. MIS does, however, require many intraoperative X-rays to compensate for the surgeon's lack of direct line-of-vision, which can make it less accurate than open surgeries.
Using Mazor Robotics technology allows our surgeons to overcome these limitations and perform precise spinal fusion with minimal radiation.
What are the advantages of spinal fusion with Mazor Robotics technology?
It guides the surgeon's tools and the implants in both open and minimally invasive surgery, while ensuring the highest levels of accuracy of implant placement. It decreases soft tissue trauma, preserving surrounding healthy tissue.
What is kyphoplasty?
Kyphoplasty is usually an outpatient procedure with local anesthesia for treating compression fractures of the spine — to stabilize the fracture and relieve the pain caused by the fracture.
What happens during the procedure?
During the procedure, synthetic bone cement is injected through a needle into the fractured vertebra to fill the spaces in the bone. After the needle is removed, the bone cement hardens in 10 minutes, stabilizing the fractured vertebra.
Finding the right spot for injection can be challenging. Surgeons must accurately place the needle in the precise location to avoid spillage., which can create pressure on the nerve canals. To compensate for the lack of direct visual accessibility, surgeons usually need high levels of X-ray radiation to guide them throughout the procedure.
What are the advantages of Kyphoplasty with Mazor Robotics?
This technology allows our surgeons to create a preoperative surgical blueprint, which is a map for pinpointing the precise location for injecting the bone cement. In the operating room, the Mazor Robotics system guides the surgeon's tools with minimal radiation.
What is a biopsy?
A biopsy is the removal of a small sample of tissue for examination and diagnosis. For example, a biopsy is done to determine if the abnormal tissue is benign, malignant or infected. Biopsies can be as small as a millimeter (1/25th of an inch).
How is a biopsy performed?
Biopsies are usually taken with a needle through a small incision. To compensate for the lack of direct visual accessibility, surgeons use computed tomography (CT) and X-ray images to guide the biopsy. Finding the right spot can be difficult, especially with very small lesions. This increases the operation time, as well as radiation to the patient and may cause more tissue damage and a larger scar.
What are the advantages of biopsies performed with Mazor Robotics technology?
It allows our surgeons to create a preoperative surgical blueprint, which is a map for pinpointing the exact location for taking your biopsy. During the procedure, Mazor Robotics guides your surgeon according to your surgical blueprint, with minimal X-rays. This enhances safety by reducing exposure to radiation and minimizes soft tissue damage.
What is Scoliosis?
A normal spine, when viewed from behind, appears straight. However, a spine affected by scoliosis shows evidence of a lateral, or side-to-side curvature, with the spine looking like an "S" or "C" and a rotation of the back bones (vertebrae), giving the appearance that the person is leaning to one side. According to the Scoliosis Research Society, scoliosis is defined as a curvature of the spine measuring 10 degrees or greater.
Scoliosis is a type of spinal deformity and shouldn't be confused with poor posture.
Spinal curvature from scoliosis may occur on the right or left side of the spine, or on both sides in different sections. Both the thoracic (mid) and lumbar (lower) spine may be affected by scoliosis.
How can robotic surgery help?
Surgery treats but does not cure scoliosis; it corrects the abnormal curvature and prevents further progression of the disease.
In cases which are progressive, or when the cob angle is greater than 45º, your doctor may recommend surgery to straighten and fixate the spine, which is achieved by placing implants such as screws, rods and wires in and along the spine.
Though scoliosis is common in adolescents, we are not currently performing surgery on that age group. At Tri-City Medical Center, surgeons are utilizing the Mazor technology to correct scoliosis deformity in adults.
Surgery can offer significant pain relief and enhance daily living activities.
What are the advantages of treatment with Mazor Robotics technology?
Surgical treatment of adolescent idiopathic scoliosis requires planning and precision. Each scoliotic curvature has unique challenges and often the patient's vertebrae are deformed, twisted and abnormally small, which makes surgery challenging.
Mazor Robotics technology provides increased safety and precision in corrective surgery. It allows our surgeons to plan ahead before entering the operating room. Mazor Robotics advanced 3D planning software is used before surgery to create a unique blueprint, which is the ideal procedure for each patient's condition.
What is Renaissance?
Renaissance is Mazor Robotics' guidance system that allows surgeons to perform any spine surgery, from the simplest to the most complex — safely, accurately and efficiently while reducing radiation and optimizing clinical outcomes.
Independent scientific research has shown that using Mazor Robotics technology in minimally invasive surgery (MIS) increases surgical accuracy, lowers clinical complication rates, reduces pain and enables faster recovery and return to daily activities. Research has also shown its superior accuracy, up to 99.7% (compared to around 90% in freehand surgeries) in complex surgeries such as scoliosis corrections.
How precise is spine surgery with Mazor Robotics' Renaissance™?
Renaissance™ is designed to provide consistent accuracy to 1 mm (1/25th inch), which is superior to freehand surgeries. Mazor Robotics technology is highly precise and has been clinically validated in studies worldwide. For example, a recently published study demonstrated 98.3% accuracy for placing 3,271 implants in 635 cases in 14 international medical centers.
What are the clinical benefits of Mazor Robotics technology?
Although statistics show that spine surgeries are generally quite successful, Renaissance takes spine procedures to the next level with its consistent accuracy. Independent scientific research has shown that Mazor Robotic technology increases surgical accuracy, lowers complication rates, reduces pain and aids in faster recovery with a quicker return to daily activities when compared to open, freehand surgeries.
What are the advantages of minimally invasive surgery with Renaissance™?
In the past, Tri-City surgeons performing open spine surgery have accessed the spine by making a large incision in order to allow a full, direct-field-of-vision and access for the surgeon's hands and tools. In minimally invasive surgery, our surgeons make much smaller skin incisions.
To allow for this limited field-of-vision, surgeons use fluoroscopy (X-ray) images to view their progress. Yet, even with imaging, comparative studies demonstrate that MIS accuracy is lower than in open surgeries (which offer a better, direct field-of-vision). So, there is usually a clinical tradeoff between accuracy and low exposure to radiation versus the advantage of MIS.
When our surgeons use the Renaissance, they actually map out the surgery on a computer using CT images of the patient. Patients benefit from high levels of accuracy, low intraoperative exposure to radiation and the advantages of minimally invasive surgery.
How will my surgeon work with the Renaissance™?
At Tri-City, our surgeons always select the best treatment for your specific condition Based on your CT-scan, your surgeon will use Renaissance's advanced 3D planning software to plan the optimal surgery customized for your anatomy and diagnosis. Once in the operating room, Renaissance guides our surgeons precisely to the pre-planned anatomical location where intervention is necessary.
Our surgeons are always in control. The Renaissance is not an independent robot and does not cut or perform any action on your body. Your surgeon performs the required procedures, such as placing implants. Your surgeon is in full control of the system at all times. Also, at any stage, your surgeon can decide to continue without the assistance of the Renaissance.
What should I expect before and after my surgery?
Before your surgery
- You will have CT images taken of your spine in preparation for your procedure.
- Your surgeon will use Renaissance's advanced 3D planning software with your CT images to create a unique surgical blueprint. This also provides increased safety and precision increased safety and precision since it allows your surgeon to plan ahead, before entering the operating room.
The day of your surgery
- Once ready for your operation, you will be put under anesthesia.
- In the operating room, two fluoroscopy (low-dose X-ray) images will be taken of your spine, from the back and from the side.
- These images are merged together with your previous CT images by Renaissance's advanced 3D planning software, creating a unique 3D surgical blueprint to guide your surgeon according to the personalized preoperative surgical blueprint.
