163. Dural Lesions in Lumbar Disc Herniation Surgery – Incidence, Risk Factors and Effect on Outcome

OBJECT In this study, the authors aimed to identify specific risk factors for postdecompression lumbar disc herniation (PDLDH) in patients who have not undergone discectomy and/or fusion. METHODS Between 2007 and 2012, 493 patients with lumbar spinal stenosis underwent bilateral partial laminectomy without discectomy and/or fusion in a single hospital. Eighteen patients (herniation group [H group]: 15 men, 3 women; mean age 65.1 years) developed acute sciatica as a result of PDLDH within 2 years after surgery. Ninety patients who did not develop postoperative acute sciatica were selected as a control group (C group: 75 men, 15 women; mean age 65.4 years). Patients in the C group were age and sex matched with those in the H group. The patients in the groups were also matched for decompression level, number of decompression levels, and surgery date. The radiographic variables measured included percentage of slippage, intervertebral angle, range of motion, lumbar lordosis, disc height, facet angle, extent of facet removal, facet degeneration, disc degeneration, and vertebral endplate degeneration. The threshold for PDLDH risk factors was evaluated using a continuous numerical variable and receiver operating characteristic curve analysis. The area under the curve was used to determine the diagnostic performance, and values greater than 0.75 were considered to represent good performance. RESULTS Multivariate analysis revealed that preoperative retrolisthesis during extension was the sole significant independent risk factor for PDLDH. The area under the curve for preoperative retrolisthesis during extension was 0.849; the cutoff value was estimated to be a retrolisthesis of 7.2% during extension. CONCLUSIONS The authors observed that bilateral partial laminectomy, performed along with the removal of the posterior support ligament, may not be suitable for lumbar spinal stenosis patients with preoperative retrolisthesis greater than 7.2% during extension.

Recurrent Lumbar Disc Herniation

Study Design: Narrative review. Objectives: To identify the risk factors and surgical management for recurrent lumbar disc herniation using a systematic review of available evidence. Methods: We conducted a review of PubMed, MEDLINE, OVID, and Cochrane Library databases using search terms identifying recurrent lumbar disc herniation and risk factors or surgical management. Abstracts of all identified articles were reviewed. Detailed information from articles with levels I to IV evidence was extracted and synthesized. Results: There is intermediate levels III to IV evidence detailing perioperative risk factors and the optimal surgical technique for recurrent lumbar disc herniations. Conclusions: Multiple risk factors including smoking, diabetes mellitus, obesity, intraoperative technique, and biomechanical factors may contribute to the development of recurrent disc disease. There is widespread variation regarding optimal surgical management for recurrent herniation, which often include revision discectomies with or without fusion via open and minimally invasive techniques.

Traumatic Fracture

Objective This study was performed to explore major risk factors for traumatic fracture by comparing related data of hospitalized patients with traumatic fracture and patients with lumbar disc herniation. Methods Patients with traumatic fracture and patients with lumbar disc herniation requiring surgical treatment in the orthopedics department of our hospital from March to May 2018 were divided into a fracture group and a non-fracture group. Clinical data were collected from the two groups by questionnaires. Major risk factors for traumatic fracture were analyzed using multivariate logistic regression. Results Univariate analysis showed statistically significant differences in family history of fracture, smoking history, drinking history, sex, sleep duration, chronic disease history, osteoporosis history, age, body mass index, occupation, and education level between the two groups. Multivariate logistic regression analysis showed that patients aged 25 to 44 years were more prone to traumatic fracture than patients aged ≥65 years, male patients were more prone to fracture than female patients, drinking alcohol was a risk factor for traumatic fracture, and sufficient sleep duration (>7 hours/night) was a protective factor for traumatic fracture. Conclusion Young age, male sex, and drinking are risk factors for traumatic fracture, whereas sufficient sleep duration is a protective factor.

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.
