STUDY DESIGN: A retrospective chart review was performed from 1990-1994. OBJECTIVES: To evaluate the outcome of pathologic examination of cervical disc specimens submitted after anterior cervical discectomy. SUMMARY OF BACKGROUND DATA: This study is the first to review the outcome of pathologic examination of disc specimens after anterior cervical discectomy and fusion. METHODS: Charts were reviewed based on the procedure code of anterior cervical fusion and the main diagnoses of cervical disc and spondylosis. The following data were recorded for each patient: symptoms, examination, diagnostic studies, operative procedure, operative findings, and pathology report. Statistical analysis was performed. RESULTS: Five hundred six disc levels in 394 patients were reviewed. All patients had symptoms and examination results consistent with cervical radiculopathy. All patients had cervical radiographs and some combination of myelography, computed tomography, or magnetic resonance imaging. Findings at the time of surgery included the presence of either a herniated disc or degenerative spondylitic changes. The pathologic examination results of all specimens reported fibrocartilaginous tissue consistent with disc material with the presence of degenerative changes. No infectious, benign, or malignant process was identified at the time of surgery or on gross and histologic examination of any of the disc specimens. Using confidence intervals (95%) for exact proportions and given 500 negatives, the chance the next occurrence would be positive would be 0.0060 or 0.60% or six of 1000. CONCLUSIONS: This study shows that if the symptoms, physical examination, radiographic diagnostic studies, and surgical findings are consistent with those of cervical disc herniation of spondylosis, the chance of an unexpected, clinically important pathologic finding within the disc specimen is extremely small. The time and expense involved in routine pathologic examination of cervical disc specimens can be avoided.
STUDY DESIGN: Cervical spine manipulation and mobilization were reviewed in an analysis of the literature from 1966 to the present. OBJECTIVES: To assess the evidence for the efficacy and complications of cervical spine manipulation and mobilization for the treatment of neck pain and headache. SUMMARY OF BACKGROUND DATA: Although recent research has demonstrated the efficacy of spinal manipulation for some patients with low back pain, little is known about its efficacy for neck pain and headache. METHODS: A structured search of four computerized bibliographic data bases was performed to identify articles on the efficacy and complications of cervical spine manual therapy. Data were summarized, and randomized controlled trials were critically appraised for study quality. The confidence profile method of meta-analysis was used to estimate the effect of spinal manipulation on patients' pain status. RESULTS: Two of three randomized controlled trials showed a short-term benefit for cervical mobilization for acute neck pain. The combination of three of the randomized controlled trials comparing spinal manipulation with other therapies for patients with subacute or chronic neck pain showed an improvement on a 100-mm visual analogue scale of pain at 3 weeks of 12.6 mm (95% confidence interval, -0.15, 25.5) for manipulation compared with muscle relaxants or usual medical care. The highest quality randomized controlled trial demonstrated that spinal manipulation provided short-term relief for patients with tension-type headache. The complication rate for cervical spine manipulation is estimated to be between 5 and 10 per 10 million manipulations. CONCLUSIONS: Cervical spine manipulation and mobilization probably provide at least short-term benefits for some patients with neck pain and headaches. Although the complication rate of manipulation is small, the potential for adverse outcomes must be considered because of the possibility of permanent impairment or death.
