Abstract Background: Although many studies have been conducted on risk factors associated with lumbar disc herniation (LDH), only few studies reported on the association of these factors in comparison to LDH and lumbar disc herniation and degeneration (LDHD). There are no reported studies on a regression model incorporating these factors. As the risk factors are better described in regression models, present study aimed to develop a regression model associated with LDH and LDHD in relation to socio-demographic, behavioural and occupational factors.Methods: A case control study conducted using 104 cases with LDH and controls (n=104) without LDH. Pre-tested questionnaire was administered to all participants to gather information.Results: Among the cases with LDH, 35.6 % presented with LDHD while 64.4 % had only LDH. Among the socio-demographic characteristics, body mass index <25 kgm-2 was a significant protective factor for both LDHD (OR=0.31; 95% CI=0.13-0.72) and LDH (OR=0.39; 95% CI=0.20-0.77). Involvement in daily activities with heavy (OR=5.1; 95 % CI=2.1-11.8) and moderate strain (OR=3.1; 95 % CI=1.5-6.6) to back, sitting more than eight hours per day (OR=5.1; 95 % CI=1.0-25.7), smoking (OR=5.0; 95 % CI=1.5-16.4) and sleeping in supine position (OR=2.09; 95% CI=1.09-4.06) were significant risk factors for LDH. Only daily physical activities with heavy strain act as a significant risk factor (OR=3.1; 95 % CI=1.1-8.5) for the development of LDHD. Types of mattresses used did not have significant difference among cases and controls. Majority of cases (56.7 %) did not know the causative factor that led to LDH. According to the regression model, BMI, smoking and involvement in physical activities with moderate and heavy strain to back were considered as significant risk factors for the development of LDH or LDHD.Conclusion: BMI, smoking and daily physical activities with moderate and heavy strain to back are significant risk factors for development of LDH or LDHD in regression model.

Objective: Present study was aimed to develop a regression model for selected sociodemographic, behavioural and occupational factors with lumbar disc herniation (LDH) and lumbar disc hearniation and degeneration (LDHD) in a selected population in comparison to healthy individuals.Materials & Methods: The study was conducted using 104 cases with disc herniation and controls (n=104) without LDH. Analysis was conducted in sub groups of patients with LDH (n=67) and LDHD (n=37) in comparison to control subjects. Pre-tested questionnaire was administered to all participants to gather information.Results & Discussion: Among the cases 35.6 % presented with LDHD while 64.4 % had only LDH. Among the socio-demographic characters, body mass index <25 kgm-2 was a significant protective factor for both LDHD (OR=0.31; 95% CI=0.13-0.72) and LDH (OR=0.39; 95% CI=0.20-0.77). Involvement in daily activities with heavy (OR=5.1; 95 % CI=2.1-11.8) and moderate strain (OR=3.1; 95 % CI=1.5-6.6) to back, sitting more than eight hours per day (OR=5.1; 95 % CI=1.0-25.7), smoking (OR=5.0; 95 % CI=1.5-16.4) and sleeping in supine position (OR=2.09; 95% CI=1.09-4.06) were significant risk factors for LDH. Only daily physical activities with heavy strain act as a significant risk factor (OR=3.1; 95 % CI=1.1-8.5) for the development of LDHD. Types of mattresses used did not have a significant difference among cases and controls. Majority of cases (56.7 %) did not know the causative factor that led to LDH. According to the regression model, BMI, smoking and involvement in physical activities with moderate and heavy strain to back were considered as significant risk factors for the development of LDH or LDHD.Conclusion: In regression model BMI, smoking and daily physical activities with moderate and heavy strain to back were found to be the significant risk factors for development of LDH or LDHD.International Journal of Human and Health Sciences Vol. 05 No. 04 October’21 Page: 424-434

Background: Percutaneous endoscopic interlaminar discectomy (PEID), which poses advantages for certain types of herniated disc, is gaining wider acceptance in clinical practice. We retrospectively analyzed the efficacy of the PEID technique in treatment of calcified lumbar disc herniation. Study Design: A retrospective case-control study. Setting: University hospital in China. Objective: To evaluate the efficacy of the PEID technique in treatment of calcified lumbar disc herniation, and a comparison between calcified and noncalcified disc herniation was drawn to analyze the causes of herniated disc calcification. Methods: Data from patients who underwent full-endoscopic lumbar discectomy in our department between March 2011 and May 2013 were collected. Thirty cases with calcified lumbar disc herniation were included in the study group, and 30 age-, gender-, and body mass index (BMI)-matched cases with noncalcified lumbar disc herniation served as controls. Perioperative data, preoperative and postoperative Visual Analog Scale (VAS) scores, Oswestry Disability Index (ODI) values, MacNab scores, and postoperative low-extremity dysesthesia among patients in the 2 groups were collected. Results: The values of computed tomography (CT) in the calcified group were significantly higher than those in the noncalcified group (P < 0.01). The preoperative disease courses in the 2 groups were similar. However, there was a statistically significant difference in the duration of traditional Chinese medicines (TCM) administration (P < 0.01). VAS and ODI scores improved significantly after surgery, but there were no significant differences between the 2 groups (P > 0.05). Three months after surgery, the rate of low-extremity dysesthesia in the calcified group was significantly higher than that in the control group (P = 0.03) but became similar at 6 months. By applying MacNab criteria the proportions of good and excellent were greater than 90% in both groups, and there was no difference between groups (P > 0.05). Limitations: The sample size was small in this retrospective study. Conclusion: The PEID technique is an effective method in the treatment of calcified lumber disc herniation, although the rate of postoperative dysesthesia is higher in this group during the early postoperative period. Long-term TCM administration may be related to the calcification of herniated lumbar discs.
