Basilar invagination is defined as abnormal upward and/or posterior displacement of the odontoid leading to ventral compression of the cervicomedullary junction. This condition leads to lower cranial neuropathies, sensorimotor deficits, and myelopathy. These symptoms can persist even after posterior decompression, which is an indication for ventral decompression. Transoral approaches to the upper cervical spine carry significant morbidity, limiting their utility. The endonasal approach to the upper cervical spine presents an alternative for patients with amenable anatomy...

STUDY DESIGN: Descriptive study. OBJECTIVES: This study aimed to evaluate the hidden blood loss (HBL) of patients who underwent lumbar fusion surgery for degenerative spine and to analyze its risk factors. SUMMARY OF BACKGROUND DATA: When planning transfusion strategies, blood loss calculation is important. However, in clinical practice, spine surgeons usually ignore the possibility that a large amount of HBL may occur after lumbar fusion surgery...

STUDY DESIGN: This is a genetic association study. OBJECTIVE: To investigate association between suppressor of cytokine signaling-3 (SOCS3) gene polymorphisms and the onset and progression of lumbar adolescent idiopathic scoliosis (AIS) and to further clarify its role in the regulation of SOCS3 expression in AIS patients. SUMMARY OF BACKGROUND DATA: Some studies showed that muscle development imbalance may be responsible for onset and progression of lumbar AIS...

STUDY DESIGN: This is retrospective study. OBJECTIVE: Our purpose is to examine the state of the L5-S1 disk after long fusion arthrodesis stopping at L5 in adult scoliosis, and to identify the risk factors for disk degeneration. SUMMARY OF BACKGROUND DATA: The long fusion arthrodesis surgery for adult scoliosis has shown to have good clinical results. However, there is still some controversy with reference to the potential caudal extents of the fusion, that is, L5 or S1...

OBJECTIVE: The objective of this study was to assess if derotation connectors influence axial, coronal, and sagittal results in AIS surgery. SUMMARY OF BACKGROUND DATA: Conventional reduction techniques remain limited in their ability to reduce axial torsion...

STUDY DESIGN: Prospective questionnaire. OBJECTIVE: To describe patient perceptions of minimally invasive spine (MIS) versus open surgery, and to determine which factors are most heavily considered by the patient when choosing between approaches. SUMMARY OF BACKGROUND DATA: MIS surgery has increased in popularity due to proposed advantages in the perioperative and immediate postoperative periods. However, patient preferences and understanding with regard to the differences between MIS and open surgery have not been elucidated...

STUDY DESIGN: Description of a navigated, single-step, minimally invasive technique for the placement of pedicle screws. OBJECTIVE: To describe a new technique for minimally invasive placement of pedicle screws in the lumbar spine using O-arm and StealthStation navigation in combination. SUMMARY OF BACKGROUND DATA: Minimally invasive surgical techniques are described in the literature as safe and effective methods for pedicle screw instrumentation...

STUDY DESIGN: A retrospective, economic analysis. OBJECTIVE: The objective of this article is to analyze the distribution of 90-day payments, sources of variation, and reimbursement for complications and readmissions for primary ≥3-level posterior lumbar fusion (PLF) from Medicare data. A secondary objective was to identify risk factors for complications. SUMMARY OF BACKGROUND DATA: Bundled payments represent a single payment system to cover all costs associated with a single episode of care, typically over 90 days...

Spine-based fixation of magnetically controlled lengthening devices has been successfully performed for children with early-onset scoliosis. However, spinal manipulation may lead to ossifications, stiffness, and autofusion as previously described. To avoid these problems, a surgical technique combining bilateral externally controlled magnetic device implantation with a rib cradle and pelvic hook fixation was introduced by us in 2011. By using a bilateral single-rib or double-rib cradle fixation and a pelvic hook, the magnetic device is percutaneously inserted...

STUDY DESIGN: This is a retrospective study. OBJECTIVE: To study the differences in definition of "inpatient" and "outpatient" [stated status vs. actual length of stay (LOS)], and the effect of defining populations based on the different definitions, for anterior cervical discectomy and fusion (ACDF) and lumbar discectomy procedures in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. SUMMARY OF BACKGROUND DATA: There has been an overall trend toward performing ACDF and lumbar discectomy in the outpatient setting...

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: The purpose of this study was to evaluate the effect of postoperative ketorolac administration (ie, dosage and duration of use) on pseudarthrosis following thoracolumbar posterolateral spinal fusions. SUMMARY OF BACKGROUND DATA: Ketorolac is a nonsteroidal anti-inflammatory drug often administered for pain control after spine surgery. The main concern with ketorolac is the risk of pseudarthrosis following fusion...

In the United States, cervical total disk arthroplasty (TDA) is US Federal Drug Administration (FDA) approved for use in both 1 and 2-level constructions for cervical disk disease resulting in myelopathy and/or radiculopathy. TDA designs vary in form, function, material composition, and even performance in vivo. However, the therapeutic goals are the same: to remove the painful degenerative/damaged elements of the intervertebral discoligamenous joint complex, to preserve or restore the natural range of spinal motion, and to mitigate stresses on adjacent spinal segments, thereby theoretically limiting adjacent segment disease (ASDis)...

STUDY DESIGN: Retrospective study. OBJECTIVE: To evaluate how each type of sagittal cervical alignment affects the motion of the upper and subaxial cervical spine using kinematic magnetic resonance imaging. SUMMARY OF BACKGROUND DATA: The sagittal malalignment of the cervical spine from degeneration in the subaxial cervical spine reflects a disruption in the kinematic properties of the cervical spine and affects the motion of adjacent segments...
