STUDY DESIGN: A prospective cohort study. OBJECTIVE: The current study utilized quantitative gait analysis to examine the relationship of fear-avoidance beliefs to gait patterns in patients with adult degenerative scoliosis (ADS). SUMMARY OF BACKGROUND DATA: Among patients with chronic spine pain, fear-avoidance beliefs are predictive of behavioral deficiencies, poor work and surgery outcomes. The impact of such beliefs on patients with major spinal deformity has yet to be investigated...

STUDY DESIGN: Case-control study. OBJECTIVE: To determine the incidence, impact, and risk factors for wound complications within 30 days following elective adult spinal deformity surgery. METHODS: Current Procedural Terminology and International Classification of Diseases, Ninth Edition, diagnosis codes were used to query the database for adults who underwent spinal deformity surgery from 2010 to 2014. Patients were separated into groups of those with and without wound complications...

PURPOSE: Widely used in traumatic pelvic ring fractures, the iliosacral (IS) screw technique for spino-pelvic fixation remains anecdotal in adult spinal deformity. The objective of this study was to assess anatomical variability of the adult upper sacrum and to provide a user guide of spino-pelvic fixation with IS screws in adult spinal deformity. METHODS: Anatomical variability of the upper sacrum according to age, gender, height and weight was sought on 30 consecutive pelvic CT-scans...

BACKGROUND: Smoking status has been shown to affect postoperative outcomes after surgery. The aim of this study is to determine if patients' smoking status impacts 30-day complication and re-admission rates after elective complex spinal fusion (≥3 levels). METHODS: The medical records of 839 adult spinal deformity patients undergoing elective complex spinal fusion (≥3 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 124(14...

PURPOSE: Evaluation and surgical management for adult spinal deformity (ASD) patients varies between health care providers. The purpose of this study is to identify appropriateness of specific approaches and management strategies for the treatment of ASD. METHODS: From January to July 2015, the AOSpine Knowledge Deformity Forum performed a modified Delphi survey where 53 experienced deformity surgeons from 24 countries, rated the appropriateness of management strategies for multiple ASD clinical scenarios...

STUDY DESIGN: A propensity-matched comparison of risk factors for proximal junctional failure (PJF), which is a symptomatic proximal junctional kyphosis developing after corrective surgery for adult spinal deformity (ASD). OBJECTIVE: To elucidate the role of bone strength for developing PJF. SUMMARY OF BACKGROUND DATA: PJF, a devastating complication of corrective surgery for ASD, often recurs even after revision surgery. Most studies of risk factors for PJF are retrospective and have a selection bias in surgical strategy, making it difficult to identify modifiable PJF risk factors...

STUDY DESIGN: Cross-sectional, observational study. OBJECTIVE: To study the occurrence of sagittal malalignment, the adaptability of a simplified sagittal modifiers grading of the Scoliosis Research Society (SRS)-Schwab adult spinal deformity classification (ASD), and the deformity-specific SRS questionnaire version 30 (SRS-30) in an unselected adult cohort with symptomatic degenerative spinal disorders. SUMMARY OF BACKGROUND DATA: The sagittal modifiers of the SRS-Schwab ASD classification correlate with health-related quality of life (HRQoL) measures in patients with ASD...

BACKGROUND: CMIS techniques are heavily dependent on placement of lateral interbody cages. Cages with an increased lordotic angle are being advocated to improve segmental lordosis and SVA. We assessed the segmental lordosis achieved with the individual cages. We further studied three variables and the effect each had on segmental lordosis: the lordosis angle of the cage, the position of the cage in the intervertebral space, and the level that it has been placed. METHODS: This is a retrospective study of 66 consecutive patients who underwent lateral interbody fusion using lordotic cages as part of CMIS correction of scoliosis from June 2012 to January 2016...

OBJECTIVE Pedicle subtraction osteotomy (PSO) provides extensive correction in patients with fixed sagittal plane imbalance but is associated with high estimated blood loss (EBL). Anterior column realignment (ACR) with lateral graft placement and sectioning of the anterior longitudinal ligament allows restoration of lumbar lordosis (LL). The authors compare peri- and postoperative measures in 2 groups of patients undergoing correction of a sagittal plane imbalance, either through PSO or the use of lateral lumbar fusion and ACR with hyperlordotic (20°-30°) interbody cages, with stabilization through standard posterior instrumentation in all cases...

STUDY DESIGN: This is a case-control study. OBJECTIVE: The present study aimed to compare the cross-sectional areas of the psoas major and multifidus muscles between elderly patients with adult spinal deformity (ASD) and age-matched and body weight-matched controls, and to evaluate the associations between the cross-sectional areas of these muscles and the severity of spinal deformity. SUMMARY OF BACKGROUND DATA: The study included 49 female kyphosis patients with mild scoliosis (Cobb angle <20 degrees; mean age, 70...

STUDY DESIGN: Prospective multicenter analysis of Adult Spinal Deformity (ASD) patients. OBJECTIVE: To introduce the lumbar pelvic angle (LPA), a novel parameter of spinopelvic alignment. SUMMARY OF BACKGROUND DATA: The T1 Pelvic angle (TPA), a measure of global spinopelvic alignment, correlates with HRQOL, but it may not be measureable on all intraoperative x-rays. In patients with prior interbody fusion at L5-S1, the plane of the S1 endplate can be blurred, creating error in PI-LL measure...

OBJECTIVE: To report the outcome of adult spinal deformity (ASD) in patients with rod fracture (RF) after thoracolumbar fusion. METHODS: Retrospective review of prospective, multicenter database. Operative patients with ASD ≥18 years old with RF after ASD surgery and with a minimum 6-month follow-up after RF were included. Health-related quality of life scores and radiographic alignment were compared with nonparametric paired and independent testing (P < 0...

BACKGROUND: Conservative treatment in spine deformities and spine related disorders is mainly based on proper individual proprioceptive and motor control training. For these reasons, conservative treatment involves the stimulation of individual capability of perceiving/reducing deformities, blocks and/or improper spine posture by voluntary control. The literature describes that habitually adopted relaxed postures often exacerbate low back pain. Typically, youths can be referred to therapeutic programs aimed at improving the quality of body posture along with fostering the awareness of the importance of correct posture...

OBJECTIVE: Shifting national healthcare trends place increased emphasis on patient-centered care and value-based outcomes, and thus, patient-reported outcome instruments (PROIs) are often used. We sought to characterize the trends in PROI use over the past decade with regard to thoracolumbar degenerative spine disease and spinal deformity in major neurosurgical journals. METHODS: Articles were screened for PROI use through a PubMed search among five major neurosurgical journals from 2006 to 2016...

BACKGROUND CONTEXT: Non-operative management is a common initial treatment for adult spinal deformity (ASD) patients despite reported superiority of surgery with regard to outcomes. Ineffective medical care is a large source of resource drain on the health system. Characterization of ASD patients likely to elect for operative treatment from nonoperative management may allow for more efficient patient counseling and cost savings. PURPOSE: To identify deformity and disability characteristics of ASD patients that ultimately convert to operative treatment compared to those that remain non-operative and those that initially choose surgery...

BACKGROUND CONTEXT: In 2008, Mirza et al. designed and validated the first and only index capable of quantifying the complexity of spine surgery. However, this index is not fully applicable to adult spinal deformity (ASD) surgery as it does not include the surgical techniques most commonly used and most strongly associated with perioperative complications in patients with ASD. PURPOSE: The objective of this study is to develop an "Adult Deformity Surgery Complexity Index" (ADSCI) to quantify objectively the complexity of the ASD posterior surgery...
