RESUMO
OBJECTIVE: To evaluate the cervical lordosis in standing posture in healthy volunteers from the Navy Medical Center, by means of measurement of the angle of Cobb. MATERIAL AND METHODS: The present is a descriptive, cross-sectional, with descriptive statistic and stratified sampling trial. The lateral radiographs of 81 healthy volunteers were analyzed. The technique used was obtained with the patients in standing posture, with eyes opened and to assume a comfortable neutral resting position, with 1 kg. in each upper extremity. RESULTS: 56 volunteers with medical activities, 90% displayed lost of lordosis. (Min 36 degrees, Max 76 degrees mean 54 degrees). Twenty five volunteers with office activities, 60% displayed lost of lordosis (Min 22 degrees, Max. 66 degrees, Mean 47 degrees). The ranks of interval for medical activities 50 to 65 degrees and for activities of office of 35 to 50 degrees (IC 95%). CONCLUSIONS: Medical and office activities are associated with asymptomatic loss of cervical lordosis, with greater association of medical activities. Lateral radiographs in standing posture, allow suitable evaluation of the cervical spine without modifying its alignment.

BACKGROUND: Discal hernia is generally treated by discectomies that are mutilating and cause instability and low back pain in 50% of the patients. Partial arthroplasty is used in an attempt to avoid degeneration after a discectomy. METHODS: Nineteen patients from the INR (National Institute of Rehabilitation) were selected with extruded discal hernia. All inclusion criteria were met, with a minimal follow-up of 4 years. Evolution was evaluated with the Oswestry scale (OS) and x-ray studies. Statistical analysis was done with Student's t-test. RESULTS: Sixteen men and three women were included in the study, with an average age of 35.4 years. OS before surgery was 57.37% and improved to 22% (p < 0.001). The results obtained in the Prolo scale 4 years later were for the economy scale, p < 0.001 (Wilcoxon Z = 3.87) and for the functional scale, p < 0.001 (Wilcoxon Z = -3.94). The intervertebral space height (IS) before surgery was 6 and 8 mm, and 4 years later, in 12 patients it remained between 8 and 10 mm. The prosthesis had variations according to its initial placement in seven patients, and in all there was subsidence. In two cases migration surpassed the limits of the vertebral body without clinical repercussion. None of the patients required re-operation. CONCLUSIONS: Prosthetic disc nucleus device improved clinical conditions and x-rays of the patients using Oswestry, Prolo and intersomatic space height enhancement after 4 years of follow-up in 12/19 patients.
