BACKGROUND CONTEXT: - Spinal deformities are commonly associated with poor HRQOL. Several questionnaires (e.g. SRS-24 and SRS-22) have been developed to evaluate HRQOL in these conditions. In adults as well as during growth, the HRQOL is considered one of the most relevant outcomes of both conservative and surgical treatment. Rasch analysis is a powerful statistical technique for developing high quality and valid questionnaires. The SRS-24 and SRS-22 have been evaluated using the Rasch analysis, but showed poor measurement properties...

BACKGROUND CONTEXT: Patients with degenerative lumbar stenosis (DLS) adopt a forward flexed posture in an attempt to decompress neural elements. The relationship between sagittal alignment and severity of lumbar stenosis has not previously been studied. PURPOSE: We hypothesized that patients with increasing radiological severity of lumbar stenosis will exhibit worsening sagittal alignment. STUDY DESIGN: This is a cross-sectional study. PATIENT SAMPLE: Our sample consists of patients who have DLS...

BACKGROUND CONTEXT: Perioperative neurologic complications after spine surgery may increase morbidity and healthcare costs related to the procedure. PURPOSE: We estimate the national incidence of perioperative neurologic complications following anterior cervical discectomy and fusion (ACDF), posterior cervical fusion, and thoracolumbar fusion procedures using the Nationwide Inpatient Sample (NIS) data from 1999 to 2011. Additionally, we identify risk factors for developing perioperative neurologic complications and the effects of these injuries on quantifiable patient outcomes...

BACKGROUND CONTEXT: Proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) are common problems after long segment (>5 levels) thoracolumbar instrumented fusions in the treatment of adult spinal deformity (ASD). No specific surgical strategy has definitively been shown to lower the risk of PJK as the result of a multifactorial etiology. PURPOSE: To assess the incidence of PJK and PJF in patients treated with prophylactic polymethylmethacrylate(PMMA) cement augmentation at the uppermost instrumented vertebrae(UIV) and rostral adjacent vertebrae(UIV+1)...

#6
Guang Bin Zheng, Byung-Hak Yoon, Jae Hyup Lee
BACKGROUND CONTEXT: Activin A/BMP-2 chimera (AB204) could promote bone healing more effectively than recombinant bone morphogenetic protein 2 (rhBMP-2) with much lower dose in rodent model, but there is no report about the effectiveness of AB204 in a large animal model. PURPOSE: The purpose of this study was to compare the osteogenesis and fusion rate between AB204 and rhBMP-2 using biphasic calcium phosphate (BCP) as a carrier in beagle's posterolateral lumbar fusion model...

BACKGROUND CONTEXT: The incidence of proximal junctional kyphosis (PJK) ranges from 5-46% following adult spinal deformity (ASD) surgery. Approximately 66-76% of PJK occurs within 3 months of surgery. A subset of these patients, reportedly 26-47%, develop proximal junctional failure (PJF) within 6 months postoperatively. To date, there are no studies evaluating the impact of prophylactic vertebroplasty on PJK/PJF incidence at long term follow-up. PURPOSE: The purpose of this study is to evaluate the long term radiographic and clinical outcomes, and incidence of PJK and PJF, after prophylactic vertebroplasty for long segment thoracolumbar posterior spinal fusion...

BACKGROUND CONTEXT: Prior reports have compared posterior column osteotomies to pedicle subtraction osteotomies in terms of utility for correcting fixed sagittal imbalance in adolescent patients with deformity. No prior reports have described the use of multilevel Smith-Petersen Osteotomies (SPOs) alone for surgical correction in the adult spinal deformity (ASD) population. PURPOSE: To determine the utility of multilevel Smith-Petersen Osteotomies (SPOs) in the management of global sagittal imbalance in adult spinal deformity (ASD) patients...

Background/context The evidence for the treatment for non-specific chronic low back pain (ns CLBP) is very weak. Besides the complexity of the pain experience, a good biological marker or tool enabling identification of a pain generator is lacking. Hybrid imaging, combining Single Photon Emission Computerized Tomography (SPECT) with Computerized Tomography (CT)-scan, has been proposed as useful in the diagnostic workup of CLBP patients. Purpose To evaluate the sensitivity of SPECT-CT in patients with ns CLBP (group I) as compared to patients without CLBP (Group II)...

BACKGROUND CONTEXT: The patient experience of care as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey is currently used to determine hospital reimbursement. The current literature inconsistently demonstrates an association between patient satisfaction and surgical outcomes. PURPOSE: To determine whether patient satisfaction with hospital experience is associated with better clinical outcomes in lumbar spine surgery...

Seok Woo Kim, Chulyoung Jang, Myung Ho Yang, Seonjong Lee, Je Hyun Yoo, Yoon Hae Kwak, Ji Hyo Hwang
BACKGROUND CONTEXT: Prevertebral soft tissue swelling (PSTS) after anterior cervical spine surgery (ACSS) has been regarded as one of the critical complications that cause airway obstruction. Still, however, no research has dealt with how PSTS returns to pre-surgery status after ACSS; most recommendations are being performed without information about its natural course, focusing on acute-phase swelling after surgery. PURPOSE: To examine how long post-surgery PSTS lasts and when it returns to its pre-surgery state; to analyze the actual influence of a number of factors to observe the natural progress of post-surgery PSTS...

Douglas S Weinberg, Brian Z Hedges, Jonathan E Belding, Timothy A Moore, Heather A Vallier
BACKGROUND CONTEXT: Previous studies have suggested pulmonary complications are common among patients undergoing fixation for traumatic spine fractures. This leads to prolonged hospital stay, worse functional outcomes, and increased economic burden. However, only limited prognostic information exists regarding which patients are at greatest risk for pulmonary complications. PURPOSE: To identify factors predictive of perioperative pulmonary complications in patients undergoing fixation of spine fractures...

BACKGROUND CONTEXT: During spine surgery, the spinal cord is electrophysiologically monitored via transcranial electrical stimulation motor evoked potentials (TES-MEP) to prevent injury. TES-MEP involves the use of either constant-current or constant-voltage stimulation; however, there are few comparative data available regarding their ability to adequately elicit compound motor action potentials (CMAPs). We hypothesized that the success rates of TES-MEP recordings would be similar between constant-current and constant-voltage stimulation in patients undergoing spine surgery...

CONTEXT: Classification criteria are recommended for diseases that lack specific biomarkers in order to improve homogeneity in clinical research studies. Since imaging evidence of lumbar disc herniations (LDH) may not be associated with symptoms, clinical classification criteria based upon patient symptoms and physical examination findings are required. PURPOSE: This study aimed to produce clinical classification criteria to identify patients with radicular pain caused by LDH...

BACKGROUND CONTEXT: In each specific habitual standing posture, gravitational forces determine the mechanical setting provided to skeletal structures. Bone quality and resistance to physical stress is highly determined by habitual mechanical stimulation. However, the relationship between bone properties and sagittal posture has never been studied in children. PURPOSE: To investigate the association between bone physical properties and sagittal standing postural patterns in 7-year-old children...

Se-Woong Chun, Chai-Young Lim, Keewon Kim, Jinseub Hwang, Sun G Chung
BACKGROUND CONTEXT: Clinicians regard lumbar lordotic curvature (LLC) with respect to low back pain (LBP) in a contradictory fashion. The time-honored point of view is that LLC itself, or its increment causes LBP. On the other hand, recently, the biomechanical role of LLC has been emphasized and loss of lordosis is considered a possible cause of LBP. The relationship between LLC and LBP has immense clinical significance, since it serves as the basis of therapeutic exercises for treating and preventing LBP...

BACKGROUND CONTEXT: Blood transfusions in spine surgery are shown to be associated with increased patient morbidity. The association between transfusion performed using a liberal hemoglobin (Hb) trigger-defined as an intraoperative Hb level of ≥10 g/dL, a postoperative level of ≥8 g/dL, or a whole hospital nadir between 8 and 10 g/dL-and perioperative morbidity and cost in spine surgery patients is unknown and thus was investigated in this study. PURPOSE: This study aimed to describe the perioperative outcomes and economic cost associated with liberal Hb trigger transfusion among spine surgery patients...

BACKGROUND CONTEXT: Open door laminoplasty (ODLP) also can lead to significant postoperative motion restriction that further increases over time, for which one of possible factor is the bony impingement between neighboring posterior bony arches. Previously, we reported this phenomenon and modified technique of ODLP, wedge-shaped resection of the posterior bony arch that produced greater range-of-motion (ROM) of the cervical spine and less posterior neck pain compared to conventional ODLP in one-year follow-up time, but no longer follow-up outcomes of the surgical technique has been reported...
