“…Moreover, NIRSp measurement might be affected by differences in skin, subcutaneous fat tissue and muscle tissue volume and blood build-up. There are studies indicating that paravertebral muscle volume changed based on age and gender [18]. However, since our study found no statistically significant difference between groups in terms of age, gender and BMI, we think that NIRSp measurements were not affected by those factorsin our study.…”

Objectives: To assess spinal and cerebral oxygenation with near-infrared spectroscopy method during spinal surgery in prone position. Methods: This prospective study included 64 patients, who were prepared for posterior spinal instrumentation and laminectomy surgeries. Group 1: 31 patients who had posterior spinal instrumentation; Group 2: 33 patients who had at least two levels of disk operation (Laminectomy). The following were recorded for all patients before and after anesthesia induction in supine position, after induction in prone position, during operation (beginning, middle and end of surgery) in prone position and before waking up in supine position: cerebral oxygen saturation (NIRSs) measurements, spinal oxygen saturation (NIRSp) measurements, peripheral oxygen saturation (SpO2), heart rate (HR), invasively monitored systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP) values. Results: There was no significant difference between two groups in terms of the variables of age, weight, anesthesia and surgery duration (p > 0.05). MAP values were significantly different in both groups before induction, during operation and postoperative periods (p < 0.05). NIRSs were significantly lower at midoperation and at the end of operation (p < 0.05). NIRSp values had no significant difference in any period (p > 0.05). We found no significant difference between groups in HR, SAP, DAP, MAP, NIRSs and NIRSp parameters (p > 0.05) compared at different times. Conclusions: MAP dropped depending on induction and prone position. Cerebral oxygenation significantly decreased at the time of mid-operation and at the end of operation but spinal oxygenation had no significant decresase. Compared to laminectomy, posterior stabilization surgery did not pose an additional risk to the patients in terms of spinal and oxygen saturation.

Background: Low back pain is a common health problem in the younger population. Spinal degeneration is the most common cause of low back pain. Objectives: The purpose of this study was to investigate the most common causes of low back pain with MRI in young people under the age of 40 and to determine gender differences, if any. Methods: This is a retrospective study on 200 consecutive patients between the ages of 17 -39 who had lumbar MRI (1.5 T MRI). Patients were included in the study based on the information collected from the radiological database system and neurosurgical clinical archives between SeptemberOctober 2017. Spinal mass, spondylolisthesis, disc degeneration, multifidus muscular atrophy, and congenital anomalies were investigated. Studied parameters were compared in male and female patients. Results: Disc degeneration or hernia was observed in 132 patients (66%) and no gender difference was found for a disc hernia (P = 0.376 Chi-Square test). The most frequent disc hernia was detected at the level L5 -S1. Multifidus muscular atrophy was identified in 54 (27%) of all patients and it was higher in women (P < 0.001, Chi-Square test). Accepted change of lumbar lordosis was detected only in 10 patients. Conclusions: Disc herniation is the most common causes of low back pain in young people under the age of 40 and there are no gender differences.

“…Previous studies have focused on the association between fat infiltration of LMM and low back pain, and most of concluded that LMM fat infiltration is associated with low back pain [18,[28][29][30][31]. The prevalence and severity of LMM fat infiltration increase with age [32,33]. However, few studies have been performed to examine the association between LMM fat infiltration and SSI development following spine surgery.…”

Background: The aim of this study was to investigate the correlation between lumbar multifidus fat infiltration and lumbar postoperative surgical site infection (SSI). Several clinical studies have found that spine postoperative SSI is associated with age, diabetes, obesity, and multilevel surgery. However, few studies have focused on the correlation between lumbar multifidus fat infiltration and SSI. Method: A retrospective review was performed on patients who underwent posterior lumbar interbody fusion (PLIF) between 2011 and 2016 at our hospital. The patients were divided into SSI and non-SSI groups. Data of risk factors [age, diabetes, obesity, body mass index (BMI), number of levels, and surgery duration] and indicators of body mass distribution (subcutaneous fat thickness and multifidus fat infiltration) were collected. The degree of multifidus fat infiltration was analyzed on magnetic resonance images using Image J. Results: Univariate analysis indicated that lumbar spine postoperative SSI was associated with urinary tract infection, subcutaneous fat thickness, lumbar multifidus muscle (LMM) fat infiltration, multilevel surgery (≥2 levels), surgery duration, drainage duration, and number of drainage tubes. In addition, multiple logistic regression analysis revealed that spine SSI development was associated with sex (male), age (> 60 years), subcutaneous fat thickness, LMM fat infiltration, and drainage duration. Receiver operating characteristic curve analysis indicated that the risk of SSI development was higher when the percentage of LMM fat infiltration exceeded 29.29%. Furthermore, Pearson's correlation analysis demonstrated that LMM fat infiltration was correlated with age but not with BMI. Conclusion: Indicators of body mass distribution may better predict SSI risk than BMI following PLIF. Lumbar Multifidus fat infiltration is a novel spine-specific risk factor for SSI development.
