A retrospective review.The objective is to evaluate subsidence related minimally invasive lateral retroperitoneal lumbar interbody fusion by reviewing our experience with this procedure.Polyetheretherketone intervertebral cages of different lengths, widths, and heights filled various allograft types are commonly used as spacers in fusions. Subsidence a potential complication. To date, there no published reports specifically addressing subsidence, because it relates series patients undergoing...
In the surgical treatment of spinal deformities, importance restoring lumbar lordosis is well recognized. Smith-Petersen osteotomies (SPOs) yield approximately 10° per level, whereas pedicle subtraction result in as much 30° increased lordosis. Recently, selective release anterior longitudinal ligament (ALL) and placement lordotic interbody grafts using minimally invasive lateral retroperitoneal transpsoas approach (XLIF) has been performed an attempt to increase while avoiding morbidity...
Object The minimally invasive lateral transpsoas approach for interbody fusion has been increasingly employed to treat various spinal pathological entities. Gaining access the retroperitoneal space and traversing abdominal wall poses a risk of injury major nervous structures. Nerve can potentially lead paresis musculature bulging wall. Abdominal nerve resulting from not previously reported. authors describe case series patients presenting with after undergoing approach. Methods...
Traditional procedures for correction of sagittal imbalance via shortening the posterior column include Smith-Petersen osteotomy, pedicle subtraction and vertebral resection. These require wide exposure spinal posteriorly, may be associated with significant morbidity. Anterior longitudinal ligament (ALL) release using minimally invasive lateral retroperitoneal approach a resultant net lengthening anterior has been performed as an alternative to increase lordosis. The objective this study was...
Background and Purpose— The objective of this study was to characterize demographics, treatments, outcomes in the management unruptured cerebral aneurysms United States using a national healthcare database. Methods— Clinical data were derived from Nationwide Inpatient Sample for years 1997 through 2006. Patients with identified appropriate International Classification Diseases, 9th Revision code (437.3). Hospitalizations, length stay, hospital charges, discharge pattern, age gender...
Acute spinal cord injury (SCI) is commonly treated by elevating the mean arterial pressure (MAP). Other potential interventions include cerebrospinal fluid drainage (CSFD).To determine efficacy of aggressive MAP elevation combined with intrathecal (ITP) reduction; our primary objective was to improve blood flow (SCBF) after SCI.All 15 pigs underwent laminectomy. Study groups included control (n = 3); SCI only (SCI + MAP) CSFD CSFD) and both 3). SCBF measured laser Doppler flowmetry.In group,...
Unstable fractures at the thoracolumbar junction often require extended, posterior, segmental pedicular fixation. Some surgeons have reported good clinical outcomes with short-segment constructs if additional pedicle screws are inserted fractured level. The goal of this study was to quantify biomechanical advantage index-level screw in a fracture model.Six human cadaveric T10-L4 specimens were tested. A 3-column injury L-1 simulated, and 4 posterior tested as follows: one-above-one-below...
Object An interspinous anchor (ISA) provides fixation to the lumbar spine facilitate fusion. The biomechanical stability provided by Aspen ISA was studied in applications utilizing an anterior interbody fusion (ALIF) construct. Methods Seven human cadaveric L3–S1 specimens were tested following states: 1) intact; 2) after placing at L4–5; 3) ALIF with ISA; 4) and screw/plate system; 5) removing (ALIF plate only); 6) 7) applying bilateral pedicle screws rods. Pure moments (7.5 Nm maximum)...
Purpose Even though plate and screw designs in anterior cervical discectomy fusion (ACDF) have evolved to improve stability enhance patient outcomes, some argue that pre-tapping remained the best option. The purpose of this study is evaluate outcomes complications self-drilling, self-tapping screws their efficacy maintaining instrumentation position plated ACDFs. Methods In retrospective case series, patients who underwent ACDF with plating selfdrilling, from February 2021 May 2023 were...
INTRODUCTION: Spine diseases pose a significant burden on individuals' health and quality of life, affecting millions worldwide. However, ensuring diverse representation in spine disease-related clinical trials, particularly concerning race ethnicity, is essential for developing therapies that are effective safe all populations. METHODS: Detailed trial records from US trials registered ClinicalTrials.gov relating to disease were completed included patients over the age 18 analyzed. Data...
