The goal of a posterior spinal fusion is to . A combination of an inflammatory response, vascular changes, ischemia, and venous congestion likely plays a role in cellular apoptosis, axon degeneration, and changes in the myelin that result in the signs and symptoms of degenerative cervical myelopathy.22,23 Degenerative changes occur as a normal part of aging.1,6,22,24, There are two main components of cord compression: static and dynamic (Table 3).7,10,20,22.

Patients most often experience lower motor neuron symptoms at the level of the pathology and upper motor neuron symptoms below this level.21,29, The most common physical examination findings include decreased and possibly painful range of motion in the cervical spine, Lhermitte sign, hyperreflexia, clonus, upper motor neuron reflexes, a wide-based ataxic gait, spasticity, atrophy of intrinsic hand muscles, and upper extremity segmental weakness.20 These physical examination findings localize the pathology to the spinothalamic and corticospinal tracts, which are affected first because of their lateral location in the spinal cord.20,21, The physical examination findings associated with degenerative cervical myelopathy tend to be more specific than sensitive (Table 5).26,3033 The presence of sustained clonus or the Babinski sign was found to have 13% sensitivity and 100% specificity for upper motor neuronassociated myelopathy.30 Presence of the Hoffmann sign (sensitivity = 59% to 67%; specificity = 81%) and inverted brachioradialis reflex, also called inverted supinator sign, (sensitivity = 51%; specificity = 81%) have demonstrated higher sensitivity while maintaining good specificity for the condition.30 Evaluation for the Hoffmann sign is shown in Figure 5, and a video is available at https://www.youtube.com/watch?v=blj6Y0rrmtw.

Next, the lower back muscles, called erector spinae, are stripped off the lamina on both sides and at multiple levels. If an infection is the problem, it can spread beyond the cervix to the uterus and fallopian tubes and into the pelvic and abdominal cavity and cause life-threatening infection. Surgical management is indicated for patients with moderate to severe myelopathic signs and symptoms; however, even with surgery, many patients have residual deficits. Revision rates for surgery on the cervical spine can be high, and vary by the type of procedure performed. Bone grafts help stimulate new bone growth between the fused segments.

When decompression is performed above a fused segment, the integrity of the strong spinal ligaments, which act as tough bands to support and stabilize the spine (especially while bending forward), can be compromised due to excision, eventually leading to segmental instability in the region. Spinal fusion was first described in the early 1900's for the treatment of Pott's disease in the thoracolumbar spine [1,2,3].The anterior approach for cervical arthrodesis was introduced in the 1950's and subsequently became increasingly popular as it allowed access to anterior pathology [4,5,6,7].Despite technological advancements in spinal instrumentation and biologics, failed .

The most commonly failed surgeries resulting from a misdiagnosis of the above conditions are failed cervical fusion, failed lumbar laminectomy and failed lumbar discectomy. In North America, the published annual incidence is 41 per 1 million and prevalence is 605 per 1 million.3,14 In the United States alone, 15,000 to 20,000 people are hospitalized every year for treatment of degenerative cervical myelopathy at a cost of several hundred million dollars.17 The average age at presentation is 64 years, it is more common in men (3:1 male-to-female ratio), and C5C6 is the most common level of cord compression followed by C6C7 and C4C5.1,18,19, The high prevalence of asymptomatic individuals with radiographic evidence of cervical degeneration presents a challenge in determining the burden of this condition and supports the importance of a thorough clinical history and physical examination to avoid overdiagnosis. This additional stress is felt to contribute to a higher incidence of degeneration of adjacent segments, which could result in pain and the need for additional surgery in the future.
