The role of environmental and seasonal factors in spine deep surgical site infection: the air pollution, a factor that may be underestimated.

Background: Different strategies have been described in order to reduce spine deep surgical site infection (SSI); however, non-intervenable items such as environmental factors remain as one of the main concerns for spine surgeons.

Methods: A retrospective cohort study was designed in order to evaluate the effect of environmental factors such as temperature, humidity and particularly the air pollution index (PM 2.5) on spine surgical site infection.

The effect of cage type on local and total cervical lordosis restoration and global spine alignment in single-level anterior cervical discectomy and fusion based on EOS imaging: A comparison between standalone conventional interbody polyether ether ketone cage and integrated cage and plate (Perfect-C).

Background: There is a small level of evidence regarding the alterations in global spine alignment following the restoration of cervical lordosis using anterior cervical discectomy and fusion (ACDF). Different cage types are available to restore cervical lordosis through ACDF. In this study, we evaluate the impact of two types of these cages on local and global spine alignments.

Descriptive Epidemiology and Survival Rate of Osteosarcoma: The First National Population-Based Study in the Middle East (2008-2014).

Objectives: The epidemiology of osteosarcoma (OS), the most common primary bone sarcoma, was not evaluated in the Middle East. Therefore, this study aimed to examine the incidence, demographic characteristics, epidemiology, and survival rate of patients with different subtypes of OS, based on data derived from the Iran National Cancer Registry (INCR) to evaluate the influence of ethnicity and race.

Methods: All OS patients registered in the INCR between March 20, 2008, and March 20, 2014, were enrolled in this study, and information such as age, gender, cancer location, OS subtype, and survival time were evaluated statistically.

Perioperative complications of symptomatic congenital kyphosis: a retrospective cohort study.

Background: Despite the recent improvements in the surgical treatment of congenital kyphosis, this surgery may be associated with high rate of complications "particularly when patients are symptomatic preoperatively".

Materials And Methods: Medical profiles of 40 patients with symptomatic congenital kyphosis were retrospectively reviewed. Perioperative complications were recorded and divided in two groups including catastrophic complications (neurologic deficit, pulmonary thromboembolic events, and death) and major complications (infection, deep vein thrombosis, device failure, and dural injury).

Selective Thoracolumbar/Lumbar Fusion in Adolescent Idiopathic Scoliosis: A Comprehensive Review of the Literature.

In Adolescent Idiopathic Scoliosis (AIS), correction surgery can correct the maximum movement and balance of the spine. Under certain conditions for two simultaneous curvatures, the procedure, in which correcting one of the curvatures can result in the automatic correction of another curvature, is called selective fusion, attracting spine surgeons' interest because of more movement in the spine. However, the majority of surgeons have not used this technique due to the lack of sufficient information.

Comparison of coagulation profile and thromboembolic events among patients undergoing spinal surgery before and after COVID-19 pandemic.

Background: Impairment of coagulation parameters and increased rate of thromboembolism are known complications of COVID-19 infection. In this study the coagulation profile and rate of thromboembolic events between two groups of patients who underwent spinal surgery before and after the COVID-19 pandemic was compared.

Patients And Method: Clinically and laboratory negative for COVID-19 elective patients before (n: 211) and during COVID- 19 pandemic (n: 294) with spinal surgeries were included in this retrospective study.

Incidence of primary bone sarcomas in Iranian population (2008-2015): A national population-based study.

Background: Epidemiological characteristics of bone sarcomas are variant in different populations, however, there is no previous study on primary bone sarcomas among Iranian population. This study aimed to evaluate the incidence, age, sex distribution, histologic type, and location of malignant bone sarcomas, based on the Iran National Cancer Registry (INCR).

Methods: This was a national population-based study using INCR data from March 20, 2008, to March 20, 2015, on patients who were diagnosed with primary bone sarcomas of the appendicular (C-code:40) and axial skeleton (C-code 41), excluding skull and face bones.

Iatrogenic long thoracic nerve injury and scapular winging in posterior spinal fusion surgery: A case report.

This is an extremely rare case of scapular winging following posterior spinal fusion for correction of adolescent idiopathic scoliosis in an 18-year-old boy due to iatrogenic injury to a long thoracic nerve. Scapular winging manifested 5 days after the operation and spontaneously improved after 7 months.

Soft Tissue Sarcoma of Extremities: Descriptive Epidemiological Analysis According to National Population-based Study.

Background: Soft-Tissue Sarcoma (STS) is a heterogeneous group of neoplasms of mesenchymal origin, occurring in connective tissues. According to previously conducted studies, STS accounts for approximately 1% and 7-%15% of adult and pediatric malignancies, respectively. Almost 50%-60% of sarcomas arise from extremities and usually present as a large painless or rarely painful soft-tissue mass.

Mobile Spine Osseous Sarcoma: Descriptive Epidemiological Analysis Based on a National Population-Based Study.

Background: Primary osseous sarcomas of the mobile spine are rare bony tumors. Ewing sarcoma, chondrosarcoma, chordoma and osteosarcoma constitute the majority of primary bone sarcomas of the spine; however, other rare sarcoma tumors may also affect the spine. In order to perform an epidemiological study of theses tumors, national registries may help to evaluate data for populations with similar characteristics.

Pigmented Villonodular Synovitis Arising from Calcaneocuboid Joint in an Army Staff: A Case Report.

Pigmented villonodular synovitis (PVNS) is a locally destructive benign lesion usually affecting the synovial tissue of weight-bearing joints. Herein we reported a 20-year-old male patient who was an army staff with a foot lesion which was painful in army boots. In the beginning, the lesion was considered a ganglion cyst.

Surgical Treatment for Bisphosphonate-related Atypical Femoral Fracture: A Systematic Review.

Background: Atypical femoral fractures are the femoral fractures located anywhere between the lesser trochanter and the supracondylar flare of the femur. Long-term bisphosphonates, as the most common preventive and treatment medications for osteoporosis, are thought to have an important role in these fractures. Most of the fractures should be treated surgically, and the complications are considerable.

Epidemiologic trend of mobile spine and sacrum chordoma: A National population-based study.

Introduction: Chordoma is a rare sarcoma of the axial skeleton. The incidence of this tumor is different between races. To understand the epidemiologic characteristic and due to rarity of this pathology, large number of cases should be evaluated through national data registries.

The Survival and Incidence Rate of Ewing Sarcoma; a National Population-based Study in Iran (2008-2015).

Background: The effect of race and ethnicity on some kind of malignant bone tumors including Ewing sarcoma has been proven in different studies. In order to evaluate the latter, national cancer registries may help to increase understanding about potential cancer causes, prevention and control strategies, and apply these findings to control health problems among populations with similar characteristics.

Methods: A national population-based cancer registry study based on all patients affected by Ewing Sarcoma was registered in the Iran National Cancer Registry (INCR) between 2008 and 2015 was designed.

In Vitro Experimental Studies and Numerical Modeling to Investigate the Biomechanical Effects of Surgical Interventions on the Spine.

This paper offers a comprehensive systematic review of biomechanical research on the spine and on in vitro and numerical methods of investigation. This review focuses on interventions on the ligaments, on the facets, and on the lamina (facetectomies, laminectomies, and laminoplasties). Surgical interventions on the facets and lamina in some cases yield dissatisfactory clinical follow-up.
