BACKGROUND CONTEXT: Sagittal translation, a potential complication of pedicle subtraction osteotomy (PSO), can results in neurologic damage. However, few studies have been conducted on sagittal translation and its risk factors after PSO in patients with ankylosing spondylitis (AS). PURPOSE: To report cases of sagittal translation that developed after PSO in patients with AS with kyphotic deformity and to analyze risk factors for sagittal translation. STUDY DESIGN: A retrospective case-control study PATIENT SAMPLE: This study included 53 patients (58 cases) with AS who underwent PSO to correct their kyphotic deformity...

INTRODUCTION: This article presents the current concepts of correction of spinal deformity in ankylosing spondylitis (AS) patients. Untreated AS can be a debilitating disease. In a few patients, disease progression results in severe spinal deformity affecting not only the thoracolumbar, but also the cervical spine. Surgery for correction in AS patients has a long history. With the advent of modern instrumentation, standardization of surgical and anesthesiologic techniques, surgical safety and corrective results could be improved and experiences from lumbar osteotomies could be transferred to the cervical spine...

Global sagittal malalignment has been demonstrated to have correlation with clinical symptoms and is a key component to be restored in adult spinal deformity. In this article, various types of sagittal balance-correction osteotomies are reviewed primarily on the basis of the 3 most commonly used procedures: Smith-Petersen osteotomy, pedicle subtraction osteotomy, and vertebral column resection. Familiarity with the expected imaging appearance and commonly encountered complications seen on postoperative imaging studies following correction osteotomies is crucial for accurate image interpretation...

REVIEW
C Mazel, L Ajavon
Thoracolumbar malunion is the result of loss of correction, insufficient correction, or even no correction (both in the frontal and sagittal planes) of a thoracolumbar fracture. The main causes are incorrect assessment of the fracture's complexity (burst fracture), its potential progression to kyphosis, and associated disc or ligament damage. It can also be the result of a poorly conducted initial treatment. The types of malunion have changed over the years because of the introduction of vertebroplasty and kyphoplasty...

OBJECTIVE Adult spinal deformity (ASD) develops in the setting of asymmetrical arthritic degeneration, and can also be due to iatrogenic causes, such as prior surgery. Many patients who present with ASD have undergone prior spine surgery with instrumentation. Unfortunately, contemporary studies that evaluate the effect of prior surgery or instrumentation on perioperative outcomes, readmission rates, and need for reoperation are lacking. METHODS All ASD patients who underwent a 3-column osteotomy performed by the senior author at the authors' institution for correction of thoracolumbar spinal deformity between 2006 and 2016 were identified...

OBJECTIVE Depression and anxiety have been demonstrated to have negative impacts on outcomes after spine surgery. In patients with cervical deformity (CD), the psychological and physiological burdens of the disease may overlap without clear boundaries. While surgery has a proven record of bringing about significant pain relief and decreased disability, the impact of depression and anxiety on recovery from cervical deformity corrective surgery has not been previously reported on in the literature. The purpose of the present study was to determine the effect of depression and anxiety on patients' recovery from and improvement after CD surgery...

OBJECTIVE High-quality studies that compare outcomes of open and minimally invasively placed pedicle screws for adult spinal deformity are needed. Therefore, the authors compared differences in complications from a circumferential minimally invasive spine (MIS) surgery and those from a hybrid surgery. METHODS A retrospective review of a multicenter database of patients with spinal deformity who were treated with an MIS surgery was performed. Database inclusion criteria included an age of ≥ 18 years and at least 1 of the following: a coronal Cobb angle of > 20°, a sagittal vertical axis of > 5 cm, a pelvic incidence-lumbar lordosis angle of > 10°, and/or a pelvic tilt of > 20°...

Incidental durotomy (ID) is a common intraoperative complication of spine surgery. It can lead to persistent cerebrospinal fluid leakage, which may cause serious complications, including severe headache, pseudomeningocele formation, nerve root entrapment, and intracranial hemorrhage. As a result, it contributes to higher healthcare costs and poor patient outcomes. The purpose of this study was to clarify the independent risk factors that can cause ID during posterior open spine surgery for degenerative diseases in adults...

BACKGROUND: Children with neuromuscular disorders have a significant chance of developing scoliosis and/or hip dislocation during childhood and adolescence and often undergo surgical reconstruction. Because of their high rate of medical comorbidities, these patients are at higher risk of postoperative complications and are therefore often comanaged, along with orthopaedics, by pediatric medicine and critical care teams. Fever during the postoperative stay is a frequent occurrence and often prompts extensive diagnostic workup which increases the cost and burden on the health system but have unclear effects on the care of the patient...

BACKGROUND: Multilevel spine fusion surgery for adult deformity correction is associated with significant blood loss and coagulopathy. Tranexamic acid reduces blood loss in high risk surgery, but the efficacy of a low dose regimen is unknown. METHODS: Sixty-one patients undergoing multilevel complex spinal fusion with and without osteotomies were randomly assigned to receive low dose tranexamic acid (10 mg/kg loading dose then 1 mg·kg-1·hr-1 throughout surgery) or placebo...

BACKGROUND: Surgical treatment of severe cervicothoracic kyphotic deformity may require the use of 3-column osteotomies such as the pedicle subtraction osteotomy and vertebral column resection (VCR), or VCR with anterior longitudinal ligament resection. Such procedures are extensive and are associated with high intra- and perioperative morbidity, in part, due to the need for risky reduction maneuvers. OBJECTIVE: To describe a novel technique utilizing a laterally placed articulating hinge to facilitate kyphotic deformity correction of the cervicothoracic spine...

Meralgia paresthetica is a non-life-threatening neurological disorder characterized by numbness, tingling, and burning pain over the anterolateral thigh due to impingement of the lateral femoral cutaneous nerve. This disorder has been seen in patients with diabetes mellitus and obesity, but has also been observed in patients after procedures such as posterior spine surgery, iliac crest bone grafts, lumbar disk surgery, hernia repair, appendectomies, and pelvic osteotomies that ultimately lead to compression or damage to the lateral femoral cutaneous nerve...
