Christopher M Gubbels, Paul A Oakely, Jeb McAviney, Deed E Harrison, Benjamin T Brown
[Purpose] There is a paucity of high-quality data pertaining to the conservative management of adult spinal deformity, particularly Scheuermann's kyphosis. Long-term follow-up data for both treated and untreated Scheuermann's patients is also lacking. Given that changes in sagittal balance are associated with increased morbidity, and that these changes are increasingly prevalent in the spines of ageing populations, it is imperative that potential strategies aimed at reversing or minimizing this type of deformity are explored...

OBJECTIVESpinal deformity causing spinal imbalance is directly correlated to pain and disability. Prior studies suggest adult spinal deformity (ASD) patients with rheumatoid arthritis (RA) have more complex deformities and are at higher risk for complications. In this study the authors compared outcomes of ASD patients with RA following thoracolumbar 3-column osteotomies to outcomes of a matched control cohort.METHODSAll patients with RA who underwent 3-column osteotomy for thoracolumbar deformity correction performed by the senior author from 2006 to 2016 were identified retrospectively...

RATIONALE: Gout occurs mainly in joints, but rarely in the spine. In the spine, urate crystals can cause intervertebral space instability but rarely lead to retrolisthesis. Here, we present an extremely rare disease with gout invaded the intervertebral disc with lumbar retrolisthesis. PATIENT CONCERNS: A 61-years male patient with gout history has suffered from severe low back pain and intermittent claudication. Physical examination showed the level of muscle strength of his left first toe was 3/5...

OBJECTIVEPatients with lumbar spinal stenosis (LSS) tend to bend forward to relieve neurological symptoms. They therefore have a positive sagittal vertical axis (SVA). The importance of the SVA value is well known in the field of adult spinal deformity; however, little is known about its impact on LSS. The authors sought to investigate the impact of sagittal spinopelvic alignment on clinical outcome and health-related quality of life (HRQOL) after decompression surgery for LSS.METHODSThe authors retrospectively reviewed 83 patients who underwent lumbar decompression without fusion between January 2014 and September 2015 with a minimum follow-up of 2 years...

MINI: The present study showed that the failure of pelvic compensation would likely occur in patients with severe positive sagittal imbalance during walking. STUDY DESIGN: Case-control study for motion analysis. OBJECTIVE: To compare spinopelvic parameters using static radiographs with the values obtained using motion analysis during gait between adult spinal deformity (ASD) or lumbar spinal stenosis (LSS). SUMMARY OF BACKGROUND DATA: It is still unclear whether measurement of radiological parameters using static radiographs can reflect natural sagittal balance during gait in the patients with severe positive sagittal imbalance...

BACKGROUND: Sagittal balance is dependent on a complex interplay of the spinal curves, shape and setting of the pelvis, but also the position of the joints of the lower limb. Degenerative processes such as stiffening of the spine, aging of musculature, or reduction of the range of motion of the joints lead to imbalance of the spine after all compensatory mechanisms have been exhausted. OBJECTIVES: Based on standardized imaging, compensation mechanisms must be identified within a biomechanical analysis of the spine, the original sagittal spine profile anticipated and included in the planning of the corrective intervention...

OBJECTIVE: Anterior column realignment (ACR) is a new emerging minimally invasive surgical technique in adult spinal deformity (ASD) that has the potential to provide similar corrective ability to traditional posterior approaches. This paper reviews the current literature on the clinical efficacy and safety of ACR and illustrates an additional utilization of this technique in a case of sagittal imbalance following posterior spinal fusion with segmental instrumentation. METHODS: We performed a literature search of all published ACR reports using PubMed, including only clinical papers describing the ACR technique and reporting radiographic and/or clinical outcomes...

OBJECTIVEComplete radiographic and clinical evaluations are essential in the surgical treatment of cervical spondylotic myelopathy (CSM). Prior studies have correlated cervical sagittal imbalance and kyphosis with disability and worse health-related quality of life. However, little is known about C2-3 disc angle and its correlation with postoperative outcomes. The present study is the first to consider C2-3 disc angle as an additional radiographic predictor of postoperative adverse events.METHODSA retrospective chart review was performed to identify patients with CSM who underwent surgeries from 2010 to 2014...

STUDY DESIGN: Cadaveric feasibility study. BACKGROUND: Osteotomies to correct fixed sagittal imbalance are usually performed at L3 / L4 . AIM: To investigate the feasibility of S1 pedicle subtraction osteotomy to correct spinal deformity and spinopelvic parameters, achieving better results with a more limited exposure. The data obtained will allow designing a fixation construct specific for this osteotomy. MATERIAL AND METHODS: S1 pedicle subtraction osteotomy was performed on twelve cadaveric specimens...

INTRODUCTION: In adult spinal deformity (ASD), sagittal imbalance and sagittal malalignment have been extensively described in the literature during the past decade, whereas coronal imbalance and coronal malalignment (CM) have been given little attention. CM can cause severe impairment in adult scoliosis and ASD patients, as compensatory mechanisms are limited. The aim of this paper is to develop a comprehensive classification of coronal spinopelvic malalignment and to suggest a treatment algorithm for this condition...

BACKGROUND: Sagittal imbalance in adult spinal deformity (ASD) likely influences balance and ambulatory capacity due to muscular demand, pain, and disability. Disability measures for ASD rely heavily on ambulatory function, yet current metrics may fail to fully capture its contribution. We sought to determine (1) the utility of continuous remote step-count monitoring and activity tracking in ASD using a consumer-friendly accelerometer, and (2) investigate trends and patterns both before and after surgical intervention...

BACKGROUND: The degenerative lumbar scoliosis (DLS) patients who mainly complained about neurogenic claudication due to spinal canal stenosis are well-indicated for short segment fusion (SSF) at the affecting levels. However, it is unclear whether we should consider global sagittal balance or not. The aim of this study was to evaluate the impact of sagittal balance on the surgical outcomes of degenerative lumbar scoliosis (DLS) patients who underwent SSF. METHODS: We retrospectively reviewed 70 DLS patients who underwent SSF (less than 3 levels) and could be followed for at least 2 years...

OBJECTIVE: Minimally invasive surgery(MIS)for adult spinal deformity(ASD)is aimed at minimizing perioperative and postoperative complications. However, MIS techniques have been reported to result in suboptimal sagittal plane correction or pseudoarthrosis when used for severe deformities. The authors present their early experience with circumferential MIS(cMIS), which involves oblique lumbar interbody fusion(OLIF)with percutaneous pedicle screw(PPS)fixation using a rod cantilever technique to enhance lumbar lordosis(LL)for ASD...

STUDY DESIGN: This was an innovative concept and a preliminary prospective series. OBJECTIVE: The aim of this study was to present the concept and the technical aspects of patient-specific rods (PSR), and compare preoperative and postoperative sagittal parameters (after PSR implantation), with a special focus on the difference pelvic incidence (PI)-lumbar lordosis (LL). BACKGROUND: Despite established techniques for planning and proven correlations between quality of life and sagittal alignment, some patients do not achieve optimal radiologic outcomes after surgery and are still hypolordotic and imbalanced...

STUDY DESIGN: Retrospective Cohort. SUMMARY OF BACKGROUND DATA: Studies have shown that lumbar fusion procedures are associated with an increased risk of total hip arthroplasty (THA) dislocation. Some have speculated that the increased risk of dislocation is caused by mispositioning of the acetabular component because of spinal sagittal imbalance. Unfortunately, the exact relationship between spinal sagittal balance and cup orientation is unknown. OBJECTIVE: The objective of this study was to investigate the effect of spinal sagittal alignment on cup anteversion in THA dislocation...
