Cervical spondylosis refers to common agerelated changes in the area of the spine at the back of the neck. With age, the vertebrae (thecomponent bones of the spine) gradually form bone spurs, and their shockabsorbing disks slowly shrink. These changes can alter thealignment and stability of the spine. They may go unnoticed, or they may produce problems related to pressure on the spine and associated nerves and blood vessels. This pressure can cause weakness, numbness, and pain in various areas of the body. In severecases, walking and other activities may be compromised.
Causes and symptoms: As people age, shrinkage of the vertebral disks prompts the vertebrae to form osteophytes to stabilize the back bone. However, theposition and alignment of the disks and vertebrae may shift despite the osteophytes. Symptoms may arise from problems with one ormore disks or vertebrae. Osteophyte formation and other changes do not necessarily lead to symptoms, but after age 50, half of the population experiencesoccasional neck pain and stiffness.
STATISTICS: Of the 51 patients, 39 fullfilled the intended follow-up being 28 men (71.8%) and 11 women (28.2%). The average age was 63.5 years. Duration of symptoms ranged from 1 to 240 months (mean, 38.1 months). The mean preoperative Nurick scale score was 2.97; the mean postoperative score was 2.1. The most frequently involved vertebral body was C5 (71.7%). The follow-up period was longer than 18 months for all patients. Postoperative nonneurological complications occurred in 8 patients (15.6%). The mortality rate was 1.9% (n = 1). Postoperative results showed improvement in 25 patients (64.1%), no change in 13 (33.3%), and worsening in 1 (2.6%).
