Volume 80, Issue 9 (December 2022)
Abstract
Background: Chronic low back pain (CLBP) is one of the most common spine disorders, which is seen in 65-80% of people. Knowing the normal patterns of spine and pelvic parameters is very helpful in determining the susceptible subjects for CLBP.
Methods: This study was conducted in healthy people during April 2017 until April 2018 in Golestan hospital of Ahvaz. Inclusion criteria include; Age group 20-65 years, no history of surgery, spine disorders, and having normal radiographs were performed. People who have complained of back pain in the last three months, neuromuscular disease, lumbosacral anomalies, kyphosis and obvious scoliosis, history of spine surgery and vertebral fracture, were excluded. A 36-inch radiology stereotype was prepared in the standing position. Pelvic and spine parameters that were investigated in this research included the following, Pelvic incidence, Pelvic tilt, Sagittal Vertical Axis, T9 Sagittal Angle, Thoracic Kyphosis, Lumbar Lordosis, and Sacral Slope. All data were analyzed with SPSS software, version 24 (SPSS Inc., Chicago, IL, USA).
Results: 50 participants including 27(54%) men and 23(46%) women with an average age of 33±12.5 years and BMI of 25±5.5 kg/m2 were examined. After examining the vertebral and pelvic parameters, it was found that PI is significantly higher in women than in men (P=0.02). It was also found that with increasing age, the amount of Pelvic incidence also increases (P=0.043), so that in people over 60 years of age, the amount of pelvic incidence is significantly higher than other people (P<0.05). Further analyzes showed that BMI has a direct effect on the amount of Thoracic Kyphosis (P=0.03) and Lumbar Lordosis (P=0.04). Thus, the highest amount of Lumbar Lordosis and Thoracic Kyphosis was seen in people with BMI 30-34.9 Kg/m2.
Conclusion: The findings of the present study showed that spine and pelvis indices have an important effect on the occurrence of CLBP. Hence, it is highly recommended to check these parameters in asymptomatic people, especially in older people.

Investigating the effect of surgery time on improving the performance of fine movements of lower limbs in patients with traumatic spinal cord injury

Abstract
Background: Traumatic Spinal Cord Injury (TSCI) is one of the catastrophic events, the rate of which has been growing compared to the past decades. Complications caused by TSCI have a wide spectrum and can range from complete paralysis to numbness of the limbs. Additional to the injury severity and disability of the patient, the recovery rate depends on the treatment strategies. Despite extensive efforts and research in this field, there are still few treatment options for TSCI patients. Controversial results have been reported, however, spinal cord decompression is the only certainty for the treatment of these patients. In the present study, patients with thoracic and lumbar fractures were undergone decompression, less and more than 24 hours, and the recovery rate (RR) was compared after 6 months.
Methods: In this study, patients with lumbar and thoracic fractures who were referred to the neurosurgery department of Ahvaz Golestan Hospital during May 2019 to December 2021 were included. Decompression was performed at the fracture level as a total and at the upper and lower levels of the fracture as a partial decompression. To evaluate fine motor movements, picking up a small object with toes and following a rectangular path were used. Also, the gross motor movements, upper and lower proximal and distal muscle forces were measured.
Results: 160 patients including 133 men (83.1%) and 16.9% women (27) with 36±12 years mean age were included. The most fracture location was lumbar (53.1%), followed by the thoracic (43.1%) and fractures in both regions (3.8%). The most injured  vertebras were L1 (27.5%) and T12 (18.8%). Six months later, 61.9% of patients had a good score for removing a small object with toe, of which 67.5% belonged to patients with<24 hours surgery (P=0.01). Also, RR for ability to follow a rectangle (P=0.017) and lower limit gross motor were significantly better in patients with<24 surgery (P=0.02). However, no significant difference was found between the two groups for improved sensations (P<0.05).
Conclusion: This study showed that decompression<24 hours in TSCI is associated with a significant improvement in lower fine movements.
