Anterior Cervical Discectomy and Fusion

Anterior cervical discectomy and fusion (ACDF) is a surgical procedure used to alleviate pain, weakness, numbness, and tingling caused by pressure on the spinal cord or nerve root in the neck. The procedure involves the removal of a damaged disc in the cervical spine, which can be approached through the front of the neck. This form of surgical decompression is also known as anterior cervical decompression. The symptoms of cervical radiculopathy, such as pain, tingling, numbness, and weakness, may appear intermittently or develop gradually, and they can radiate into the shoulder, arm, and/or hand.

The surgery involves two parts: anterior cervical discectomy and fusion. During the discectomy, the damaged disc is removed from between two vertebral bones, and a fusion surgery is performed simultaneously to stabilize the cervical segment. This involves placing bone graft and/or implants in the area where the disc was removed to provide strength and stability. ACDF is commonly used to treat symptomatic cervical herniated disc, cervical degenerative disc disease, bone spurs caused by arthritis, and cervical spinal stenosis.

The anterior approach used in ACDF surgery offers direct access to the cervical discs and allows for direct visualization of the spine. This can result in direct nerve and spinal cord decompression, which can help alleviate symptoms. The anterior approach can access almost the entire cervical spine, from the top of the neck down to the point where the cervical spine meets the upper spine. Additionally, the anterior approach is associated with less postoperative pain than a posterior operation.

Cervical Fracture

he cervical vertebrae refer to the seven bones in the neck that function to support the head and connect it to the shoulders and body. When one of these vertebrae suffers a fracture or break, it is typically known as a broken neck.

Cervical fractures are usually the result of high-energy trauma, such as falls or automobile crashes, and athletes are particularly at risk. A fracture can occur when a football player "spears" an opponent with their head, when an ice hockey player is hit from behind and slams into the boards, when a gymnast falls while performing a release move, or when a diver hits the bottom of a shallow pool.

Injuries to the vertebrae can have serious consequences since the spinal cord runs through the center of the vertebrae, serving as the central nervous system's connection between the brain and the body. Damage to the spinal cord can cause paralysis or even death. Injuries to the spinal cord at the level of the cervical spine can result in temporary or permanent paralysis of the entire body from the neck down.

The type of treatment for a cervical fracture will depend on which of the seven cervical vertebrae are damaged and the extent of the fracture. A minor compression fracture can be treated with a cervical brace worn for 6 to 8 weeks until the bone heals. A more complex or extensive fracture may require traction, surgery, 2 to 3 months in a rigid cast, or a combination of these treatments.

Cervical Radiculopathy

Cervical radiculopathy refers to pain and other neurological symptoms that result from irritation of a nerve in the neck. Cervical nerves branch out to muscles that enable shoulder, arm, hand, and finger movement, as well as to skin for sensory function.

Symptoms of cervical radiculopathy can include pain, tingling, numbness, or weakness along a nerve's pathway in the shoulder, arm, and/or hand. The causes of this condition include cervical herniated discs, cervical spinal stenosis, and cervical degenerative disc disease.

Treatment options for cervical radiculopathy depend on the underlying cause and the severity of symptoms. Nonsurgical treatments such as rest, physical therapy, ice and/or heat therapy, pain management with medication or injections, and manual manipulation may be tried first. If symptoms do not improve after 6 to 12 weeks of nonsurgical treatment, surgery may be considered. Many people find that a combination of treatments provides the most effective relief for cervical radiculopathy.


Disc Replacement

The possibility of replacing worn-out discs in the lower back and neck with artificial discs, which are in varying stages of FDA approval in the USA. European surgeons have successfully implanted these artificial discs for several years, but testing is still ongoing in the US. Disc replacement surgery may be a viable option for individuals experiencing localized pain in one or two degenerated or herniated discs, as well as younger patients who prefer to maintain the range of motion of their spine. Traditional disc removal and fusion surgery has had a success rate greater than 90%, but concerns have been raised about accelerating the development of a disc problem at another level. Disc replacement surgery may slow down or prevent the development of another problem. The surgical procedure involves careful removal of most of the disc, followed by the placement of an artificial disc replacement prosthesis made of a combination of metal and very hard plastic. However, not everyone is a suitable candidate for disc replacement surgery, and conditions like osteoporosis and severe arthritis may produce poor results.

Minimally Invasive Spine Surgery (MIS)

Minimally Invasive Spine Surgery (MIS) refers to a range of surgical techniques that involve making smaller incisions and minimizing tissue damage. In spinal surgery, MIS is performed using specially designed instruments that enable the surgeon to see a larger area beneath the small incision. The field of MIS is growing, with newer techniques including endoscopic procedures and fusing two vertebrae together. The potential benefits of MIS may include smaller scars and less damage to surrounding tissues, which could result in reduced pain and blood loss. However, there is not enough data to show whether MIS provides short- and long-term benefits over traditional spine surgery. Not everyone is a suitable candidate for MIS, and factors like age, weight, lifestyle, and medical conditions must be considered. To prepare for surgery, patients may need to undergo various tests and stop taking certain medications. After the operation, patients may experience pain and will need to follow rehabilitation guidelines. Patients should consult their spine surgeon for more information.

Spinal Cord Stimulator Implantation

he process of implanting a spinal cord stimulator involves two procedures: the trial and the implantation.

First, the trial period involves the temporary implantation of a device to test its effectiveness in reducing pain. The electrodes are carefully inserted in the epidural space of the spine, guided by fluoroscopy X-rays. The trial usually requires one incision and the generator is worn externally. The success of the trial is determined by a 50% or greater reduction in pain. If the trial is unsuccessful, the wires can be easily removed. If successful, the implantation procedure is scheduled.

The implantation procedure involves the permanent placement of the device, where the generator is placed underneath the skin and the trial electrodes are replaced with sterile electrodes anchored by sutures to minimize movement. The procedure takes about 1-2 hours and is typically performed on an outpatient basis. Once the electrodes and generator are connected and running, the incisions are closed.

During the recovery period, incisions may be painful for several days, and patients are advised to avoid stretching, twisting, or reaching. Dressings are placed over the incision sites, which can be removed after about 3 days. Patients are typically advised to limit activity for 2 weeks after surgery. Complications from spinal cord stimulator surgery are rare but can include infection, bleeding, device migration, device damage, dural puncture, and spinal cord trauma.

Patients with a spinal cord stimulator are advised to be mindful of restrictions, including avoiding MRIs and turning off the device when passing through airport security or driving heavy machinery. Swimming is generally fine with a permanent, implanted generator, but not with a temporary device. The device can be removed safely if it does not provide satisfactory pain relief or if there is an infection or mechanical problem.
