    (Derman Medical Publ, 2015) Delen, Emre; Birgili, Bans; Akinci, Ahmet Tolgay; Karabulut, Derya; Turan, Fatma Nesrin; Kunduracilar, Nebile Muge; Memis, Muzaffer
    in this study, the relationship between the lower intervertebral disc herniation and the degeneration of the spine with the sagittal morphological values were investigated. The data on this study is obtained retrospectively from patients who were operated in our center with the diagnosis of lower level lumbar disc herniation. A total of 117 patients, 75 female and 42 male are included. Patients are divided into two groups as with degeneration (Pfirmann stage III-IV-V) and without degeneration (Pfirmann stage I-II). Among 117 patients, 13 were in the with degeneration group, while 104 were in the without degeneration group. The mean age of the first group was 43.0 (+/- 11.2) years, while the second group had a mean age of 45.3 (+/- 11.4) years and there were not a statistically significant differences between them (P > 0.05). Mean lumbar lordosis angle was 23.30 (+/- 8.92) degree in the first group and 28.81 (+/- 9.17) degree in the without dejeneration group, thus a lower degree was observed in the group with degeneration (P = 0.050). Segmental lordosis angle was 24.69 (+/- 8.91) and 28.17 (+/- 5.75) degree respectively, in the group with degeneration the angle value was lower (P = 0.088). The sacral surface angle in the group with degeneration was 99.51 (+/- 5.36) degree and in the second group it was 100.56 (+/- 6.03) degree. Nevertheless the difference was not statistically significant (P = 0.509). The sacral kyphosis angle is determined as 170.13 (+/- 5.41) degree and 155.59 (+/- 45.96) degree in the two groups respectively and there was statistically significant difference between them (P = 0.059). For cases with lower level lumbar disc herniation there exists a significant relationship between the disc herniation and degeneration, therefore the lumbar lordosis and the segmental lordosis angles are lower in patients with degeneration.

    Demographic Characteristics of 796 Patients Operated for Lumbar Disc Herniation in Thrace Region, Turkey
    (Derman Medical Publ, 2016) Delen, Emre; Akinci, Ahmet Tolgay; Tutunculer, Banu; Memis, Muzaffer; Kunduracilar, Nebile Muge; Sahin, Soner
    Aim: This study was designed was to determine the demographic characteristics of patients operated for lumbar disc herniation in Thrace Region, Turkey. Material and Method: We retrospectively searched our data to find out patients who had one sided, one level and only one spinal surgical intervention for herniated lumbar disc. Results: Among 796 cases, 336 (4256) were men and 460 (5831:) were women. The level of the pathology is determined as LI - 2 for 4 cases (0.56b), L2 - 3 for 15 cases (1.9%), L3 - 4 for 5 I cases (6.4%), L4 - 5 for 412 cases (51.8%) and as L5 - 51 on 314 cases (39.4%). While a total of 70 cases (8.9%) were identified on upper -levels ( LI - 2. L2 - 3, L3 - 4); 726 cases (91.1%) were found to be on lower -levels ( L4 - 5, L5 - Si). A mild positive correlation between the pathology level and physical activity intensity (P e 0.05, P = 0.103) has been demonstrated: as well as a strong negative correlation between pathology level and mean age (P < 0.05. P = -0.404). Discussion: The demographic characteristics are consistent with the literature. Physical activity intensity influence on lower -level herniations might have significance due to the large sample size. The strong negative correlation between pathology level and mean age suggests that the degeneration raises the frequency of upper -level herniations.
