Although a growing amount of literature that suggests robots are safe and can achieve comparable outcomes to conventional techniques, much this is limited by small sample sizes single-surgeon or single center series. Furthermore, it unclear what the impact robotic technology has made on operative clinical over time. This first largest multicenter study examine trends in complications after robot-assisted spine surgery 5-year period.Adult (≥18 years old) patients who underwent with...
Prospective cohort study.In spine surgery, accurate screw guidance is critical to achieving satisfactory fixation. Augmented reality (AR) a novel technology assist in placement and has shown promising results early studies. This study aims provide our experience evaluating safety efficacy with an Food Drug Administration-approved head-mounted (head-mounted device augmented (HMD-AR)) device.Consecutive adult patients undergoing AR-assisted thoracolumbar fusion between October 2020 August 2021...
An in vitro study using ovine intervertebral discs to correlate the effects of increasing advanced glycation end-products (AGEs) with disc hydration evaluated by magnetic resonance imaging (MRI).To determine relationship between level AGEs and tissue water content T2 relaxation MRI.AGEs result from nonenzymatic glycation, have been shown accumulate aging degeneration. can alter biochemical properties, including hydrophobicity extracellular matrix. Because one degenerative signs (IVD) is...
We sought to determine the role of lumbopelvic fixation (LPF) in treatment zone II sacral fractures with varying levels comminution combined anterior pelvic ring (PR) instability. also proximal extent LPF necessary for adequate stabilization and complex when only 1 transiliac-transsacral (TI-TS) screw is feasible.Fifteen L4 pelvis fresh-frozen cadaveric specimens were tested intact flexion-extension (FE) axial rotation (AR) a bilateral stance gliding hip model. Two severities simulated...
The analysis of sagittal alignment by measuring spinopelvic parameters has been widely adopted among spine surgeons globally, and imbalance is a well-documented cause poor quality life. These measurements are time-consuming but necessary to make, which creates growing need for an automated tool that measures with speed, precision, reproducibility without relying on user input. This study introduces evaluates algorithm based artificial intelligence (AI) fully automatically parameters.Two...
Study Design. A comparative study of facet joint violation (FJV) using two percutaneous surgical techniques. Objective. To compare the rate iatrogenic FJV and medial pedicle wall breach between methods screw instrumentation in thoracic lumbar spine. Summary Background Data. Variable damage to joints has been reported occur with techniques, compared open approach, which associated adjacent segment disease. Technical variations placement may pose different risks joint. Methods. Attending spine...
Meta-analysis of evidence level I to IV studies.To compare decompression alone versus plus fusion in the treatment grade degenerative spondylolisthesis (DS).Following established guidelines, we systematically reviewed 3 electronic databases assess studies evaluating patients with DS. We stratified all into 2 cohorts; first cohort underwent a decompression-type surgery, and second fusion. noted clinical outcomes, complications, reoperations, surgical details such as blood loss. Descriptive...
Multicenter cohort.To compare the robot time/screw, radiation exposure, abandonment, screw accuracy, and 90-day outcomes between robot-assisted percutaneous open approach for short lumbar fusion (1- 2-level).There is conflicting literature on superiority of minimally invasive spine surgery to techniques. A large, multicenter study needed further elucidate complications these two approaches.We included adult patients (≥18 yrs old) who underwent from 2015 2019 at four independent institutions....
Study Design: Retrospective cohort study. Objective: To determine whether a low-density (LD) screw construct can achieve curve correction similar to high-density (HD) in adolescent scoliosis. Methods: Patients treated operatively for idiopathic scoliosis between 2007 and 2011 were identified through database review. A consistent LD was used. Radiographic assessment included percent of major fractional lumbar curves, T5-T12 kyphosis, angle lowest instrumented vertebra (LIV). Costs compared...
Study Design. A retrospective review (2001–2014) was conducted using prospectively collected data at a level I trauma center. Objective. We sought to determine the incidence and characteristics of complications occurring secondary therapeutic anticoagulation in adult spine patients. Summary Background Data. Numerous studies have assessed prophylactic after surgery, but none has investigated risks doses for treatment postoperative thromboembolic events. Methods. Patients were included if they...
To determine how change in position affects displacement of midshaft clavicle fractures.Retrospective review.Level I Trauma Center.Eighty patients with displaced fractures and presence supine semiupright or upright chest radiographs taken within 2 weeks each other.Supine, semiupright, radiographs.Fracture shortening vertical on supine, radiographs.Mean was 9.42 mm [95% confidence interval (95% CI), 8.07-10.77 mm], 11.78 CI, 10.25-13.32 mm), 15.72 13.71-17.72 mm) positions, respectively....
During arthroscopic Bankart repair, penetration of suture anchors through the far cortex can compromise initial biomechanical characteristics anchor stability and repair integrity. This study compared placement a low anterior-inferior rotator interval portal (AI) vs trans-subscapularis to evaluate rate perforation as well strength. Ten matched pairs cadaveric shoulders were randomized an AI or for at 3 o'clock 5:30 positions. The following measurements obtained: (1) distance from cephalic...
Robot-assisted platforms in spine surgery have rapidly developed into an attractive technology for both the surgeon and patient. Although current literature is promising, more clinical data needed. The purpose of this paper to determine effect robot-related complications on outcomes METHODS: This multicenter study included adult (≥18 years old) patients who underwent robot-assisted lumbar fusion from 2012-2019. minimum follow-up was 1 year after surgery. Both bivariate multivariate analyses...
Robotics is a major area for research and development in spine surgery. The high accuracy of robot-assisted placement thoracolumbar pedicle screws documented the literature. authors present largest case series to date evaluating 90-day complication, revision, readmission rates surgery using current generation robotic guidance systems.
Degenerative disc disease is a common cause of chronic low back pain. Surgical intervention an invasive treatment associated with high costs. There growing interest in regenerative medicine as less but direct for discogenic pain.To evaluate clinical improvement primary pain intradiscal injection autologous bone marrow aspirate concentrate (BMAC). Study Design. Prospective cohort study. Setting. Single, multiphysician center. Patients. 32 adult patients undergoing BMAC the Interventions....
Study Design. In silico finite element study. Objective. The aim of this study was to evaluate effects six construct factors on rod and screw strain at the lumbosacral junction in an pedicle subtraction osteotomy (PSO) model: traditional inline alternative Ames-Deviren-Gupta (ADG) multi-rod techniques, number accessory rods (three-rod vs. four-rod), material (cobalt-chrome [CoCr] or stainless steel [SS] titanium [Ti]), diameter (5.5 6.35 mm), use cross-connectors (CC), anterior column...
