Correction of the overall coronal and/or sagittal plane deformities is one of the main predictors of successful spinal surgery. In routine clinical practice, spinal alignment is assessed using several spinal and pelvic parameters, such as pelvic incidence and tilt, sacral slope, lumbar lordosis, thoracic kyphosis, and sagittal vertical axis. Standard values have been defined for all these parameters, and the formulas of correction have been set for determining the surgical strategy. However, several factors can potentially bias these formulas...

Lumbar spinal stenosis (LSS) is one of the most common affecting the elderly population that may lead to loss of function and the inability to execute basic activities of daily living. While surgical decompression remains the standard of care, choosing an optimal management strategy is usually guided by a set of clinical, radiological, and measurement indices. However, to date, there is a major uncertainty and discrepancy regarding the methodology used. There is also inconsistent adoption of outcome measures across studies, which may result in huge limitations in predicting the efficacy and cost-effectiveness of different treatment paradigms...

Lumbar spinal injuries are common in elite athletes, who can present with a spectrum of ailments ranging from lumbar strain to prolapsed intervertebral discs. Sequelae can include neurological impairment and lumbar instability among other possible outcomes. This group of patients is unique in terms of their clinicoradiological presentation and treatment modalities. The primary goals of treatment are a rapid return to play and prevention of recurrence, thus prolonging the athlete's professional career. Treatment modalities can range from activity restriction to nerve root blocks and surgery...

Nonunion at the lumbosacral junction is a classic complication of long construct and deformity corrections. Iliac fixations have been extensively studied in the literature and have demonstrated superior biomechanical proprieties and lower complication rates. S2 alar iliac screws address the drawbacks of classical iliac screws but demonstrate similar biomechanical advantage. The main aim of this paper was to describe the S1 alar iliac (S1AI) screw fixation technique while evaluating our early results. S1AI screw fixation technique has the advantage of being able to achieve pelvic fixation without dissection to the S2 pedicle entry and is therefore a viable option for salvage of a failed S1 promontory screw...

STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the clinico-radiological efficacy of stand-alone minimally invasive transarticular screw (MIS-TAS) fixation without supplemental Gallie fixation in the management of mobile C1-C2 instability. OVERVIEW OF LITERATURE: Data evaluating the efficacy and feasibility of MIS-TAS in the literature is scanty. METHODS: Patients with mobile atlantoaxial instability and >2 years follow-up were included and managed by stand-alone TAS fixation using the Magerl technique and morselized allograft without additional fixation...

STUDY DESIGN: A retrospective cohort study. PURPOSE: To investigate the risk factors for postoperative delirium after spine surgery, excluding older age, which has already been established as a strong risk factor. OVERVIEW OF LITERATURE: More than 30 risk factors have been reported for delirium after spine surgery, making it challenging to identify which factors should be prioritized. We hypothesized that risk factors could not be prioritized to date because the factor of older age is very strong and influenced other factors...

STUDY DESIGN: Retrospective study. PURPOSE: This study aimed to determine the incidence of intraspinal pathologies (ISPs) in individuals with Scheuermann's kyphosis (SK) and to validate whether the routine use of magnetic resonance imaging (MRI) is necessary for preoperative evaluation. OVERVIEW OF LITERATURE: There are several studies on the necessity of routine MRI screening and prevalence of ISPs related to different types of scoliosis have been conducted...

STUDY DESIGN: Case control study. PURPOSE: To determine how the Neck Disability Index (NDI), a cervical spine-specific outcome, reflects health-related quality-of-life, and if NDI is correlated to the 36-item Short-Form Health Survey (SF-36) scores. OVERVIEW OF LITERATURE: NDI is a useful tool for assessing health-related quality of life in patients with neck pain. METHODS: We used the Pearson product-moment correlation coefficient to assess the validity of all items under NDI and SF-36, and the Pearson's correlation coefficient to assess the correlation between NDI and total SF-36 scores...

STUDY DESIGN: Retrospective review. PURPOSE: The purpose of the present study was to evaluate the role of whole-spine screening using short tau inversion recovery (STIR) or fat-suppressed T2W fast spin echo (FSE) sequences in patients with spinal tuberculosis (TB). OVERVIEW OF LITERATURE: The identification of noncontiguous multiple-level spinal tuberculosis (NMLST), symptomatic or not, is important because of its management implications. Most centers do not perform routine whole-spine magnetic resonance imaging (MRI), and the reported incidence of NMLST varies from 1...

STUDY DESIGN: Retrospective radiological review and analysis of 79 patients who underwent primary anterior cervical discectomy and fusion (ACDF) of 2 or 3 levels between 2011 and 2013. PURPOSE: This study aimed to determine the effect of the local placement of a steroid-soaked gelatin sponge after ACDF on prevertebral soft tissue swelling. OVERVIEW OF LITERATURE: Although ACDF has become a popular choice for cervical fusion, the surgical involvement of the delicate anatomy of the neck frequently results in tissue irritation and edema...

STUDY DESIGN: Retrospective, descriptive case series study. PURPOSE: To investigate the frequency, bone pattern, and associated lesions to the spine of gunshot wounds. OVERVIEW OF LITERATURE: Gunshot wounds are penetrating in nature and are caused by a bullet or projectile. These are becoming more common and are associated with significant sequelae, requiring long and costly multidisciplinary treatment. Associated spinal cord injuries (SCIs) in the civilian population represent 13%-17% of all spinal traumas...

STUDY DESIGN: Retrospective study. PURPOSE: We aimed to determine the utility of transcranial motor evoked potential (TcMEP) monitoring for the detection of intraoperative nerve root injury. OVERVIEW OF LITERATURE: Intraoperative neuromonitoring is important for the prediction of neurological injuries or postoperative paralysis. Nerve root injury can develop as a complication of adult spinal deformity (ASD) surgery. METHODS: We analyzed 295 patients who underwent ASD surgery using multi-channel TcMEP monitoring between 2010 and 2016 (58 men, 237 women; median age, 68 years; follow-up period ≥1 year)...

STUDY DESIGN: Prospective cohort study. PURPOSE: The present study aimed to evaluate the difference in the preoperative curve flexibility between the supine and prone positions in patients with adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE: In AIS, a side-bending view is necessary to differentiate a structural curve from a nonstructural curve using the Lenke classification system. However, there are no published studies about which position, supine or prone, is more effective when evaluating preoperative curve flexibility using side-bending X-ray images in AIS patients...
