Background lumbar disc herniation (lumbar disc herniation, LDH) due to lumbar disc degeneration or external force caused anular disruption, highlight the nucleus pulposus of the intervertebral disc, nerve root and (or) cauda equina clinical symptoms, the most common symptoms of low back pain and sciatica. With the pressure of life and work intensity increases, the degeneration of the lumbar spine younger, and in particular the need for long-term heavy manual labor groups of sitting young white-collar workers, students, drivers, and the long-term need to bend. Accounted for 65% -80% of low back pain patients with lumbar disc herniation in patients over the age of 40 accounted for about 20% -35%. Clinical L4 / 5 and L5 / S1 disc herniation is the most common. The basic pathological factors constitute intervertebral disc degeneration, but many factors affect the prognosis of disc herniation, lumbar force conditions, psychological factors, trauma, exercise, smoking, pregnancy, etc.. Imaging protrusion size, location, relationships to the nerve root is related to the severity of the disease. With imaging, biomechanics, endoscopic and minimally invasive techniques such as applications, so that we can identify pathological causes of low back pain early diagnosis and treatment of the LDH have more choice. Accurately determine the prognosis of the disease, the appropriate choice of treatment methods still doubts. The image area positioning the - HU Valley partition, in the description of the prominent characteristics of the three-dimensional space. Protrusion of lumbar disc herniation space distribution characteristics yet to see a large sample of cases described, projections of regional positioning with the onset of signs and symptoms and prognosis of impact remains unclear. Therefore, this study will be a large sample of cases Research (combination of imaging and clinical data), an objective description of the image area positioning distribution and treatment status of the current disc herniation and prognosis, to provide first-hand clinical decision-making and further research intervertebral disc data. Objective To describe the distribution and treatment of disc herniation image area positioning status quo, and analyze projections of regional positioning with the onset of symptoms and signs related; follow-up evaluation to explore the area of ??the image positioning and clinical outcomes (conservative surgery). Methods A retrospective analysis 2006-2010 lumbar disc herniation our hospital inpatient / outpatient 261 cases (284), the use of lumbar magnetic resonance (MR) or lumbar spine CT, in accordance with the the \The positioning of the image area, came to the lumbar disc distribution and treatment status. Incidence ODI score, JOA score, VAS score, to assess the differences of the different area of ??the image positioning onset of signs and symptoms. Follow-up evaluation, the analysis of the cases of conservative treatment and surgical treatment of cases the prognosis, explore the image area positioning correlation with clinical prognosis. 2006-2010 lumbar disc herniation results of this study, a retrospective analysis of our hospital inpatient / outpatient 261 cases (284), reached lumbar disc distribution imaging regional positioning, I layer, 1 or 2 area, a or b domain common. ODI score, JOA score, VAS score of patients with clinical signs and symptoms were evaluated according to the different positioning of the image area to be statistical analysis found that the incidence of the different area of ??the image positioning patients functional status, signs and symptoms score was no significant difference (P gt ; 0.05). Conservative treatment in this study of 46 cases (54), the average follow-up time of 28.22 months (12 to 72), 3 were lost, the image area positioning focused on: 2 layer I zone of a domain, working layer 2 b domain , Ⅲ layer (Zone 2) b domain. Statistical analysis of the onset of the conservative group and the last follow-up 0DI, JOA, the VAS, P = 0.000 lt; 0.01, significant difference, suggesting that the prognosis of a good outcome. Based on the incidence and follow-up of patients ODI, JOA, VAS score improvement rate (sagittal, horizontal position, the frontal-bit), according to the image area positioning using ANOVA test was used for statistical analysis found that the different effects of regional positioning of the patient, the prognosis and no significant difference (P gt; 0.05). Take the surgical treatment of 215 cases (229 segments), and average follow-up time of 30.20 months (12 to 126) were lost to follow-image area positioning focused on: 2 layer I zone b domain, Ⅲ layer Zone 2 b domain, Ⅲ layer 2, domain of c. Statistical analysis of the onset of the surgery group and the last follow-up ODI, JOA, the VAS, P = 0.000 lt; 0.01, significant difference, suggesting that the prognosis of a good outcome. Under both the incidence and follow-up of patients ODI, JOA, VAS score improvement rate, according to the image area positioning (sagittal, horizontal position, frontal-bit), using ANOVA test was used for statistical analysis, found that the level of bit partition affect the prognosis; prominence in a horizontal position in Area 3, the postoperative recovery somewhat less relative to other regions, but the prognostic evaluation is still excellent. In contrast to the patients in the \the b Domain patients, surgical group of patients in the JOA score better than the conservative group of patients (p lt; 0.05), but the two groups of patients will be eligible for a good prognosis. Image area positioning in the conclusion of lumbar disc herniation, I layer, 1 or Zone 2, a or b domain common; different area of ??the image positioning onset functional status, signs and symptoms score no significant differences, suggesting that based solely on the outstanding on the location of the object space distribution, functional status did not predict the onset of symptoms, the severity of the symptoms and signs score and differences. Conservative treatment in all cases last ODI, JOA, VAS score in the follow-up compared with the onset of significant improvement, significant outcome prognosis good; different effects on regional positioning the patient, there is no significant difference in prognosis of conservative treatment. For surgical patients, in all cases last follow-up ODI, JOA, VAS score than the incidence of significant improvement, significant, suggesting that the prognosis good outcome; horizontal position in the area of ??the image positioning, partition prognosis; prominence in the the level bit 3 postoperative recovery somewhat less relative to other regions, but the prognostic evaluation is still excellent. Distribution in 1-2 layer I District ab domain \
