[Functional results of surgery for cervical stenosis].
BACKGROUND
Cervical stenosis refers to the narrowing of the spinal canal or the intervertebral foramina at different anatomic levels, secondary to pathologic processes of the vertebral elements. Surgical management is used when conservative management fails. The anterior and posterior approaches are the most frequently used ones, and the surgical options resulting from these approaches are: anterior cervical diskectomy plus fusion, anterior corporectomy plus fusion, laminoplasty, laminectomy and arthroplasty.


METHODS
This is an ambispective study conducted in 195 patients with a diagnosis of cervical stenosis who required surgical treatment at our hospital from January 1995 to January 2007. The neck disability index questionnaire was applied, as well as the Nurick scale. Descriptive statistics was used with frequency and percentage measures.


RESULTS
The review of the National Rehabilitation Institute electronic records from January 1st 1995 to December 31st 2007 showed that 195 patients underwent surgery for cervical stenosis. Females were predominant. The most affected age group was 46-55 years. The most frequently affected level was C5-C6. A significant improvement was seen in the neck disability index due to pain and the Nurick scale.


CONCLUSIONS
According to world literature, mean age of patients with cervical stenosis is 57.2 years, and the most compromised levels were C4-C5 and C5-C6. Improvement was evident according to the neck disability index and the Nurick scale.
