<h3>Background</h3> As the elderly population grows, increasing prevalence of osteoporosis presents a unique challenge for surgeons. Decreased bone strength and quality are associated with hardware failure impaired healing, which may increase rate revision surgery development complications. The purpose this review is to determine impact on postoperative outcomes patients cervical degenerative disease or deformity. <h3>Methods</h3> A systematic using Preferred Reporting Items Systematic...

The purpose of this study was to (1) Determine the effect computed tomography (CT) on identification fractures involving posterior malleolus, (2) determine its operative indications, and (3) overall plan.Patients with ankle malleolus were identified. Only injuries complete preoperative plain radiographs a CT scan included. Spiral tibia pilon variants excluded. deidentified, randomized, presented 3 orthopedic surgeons. They asked questions: Is fracture simple or complex? Does injury require...

Both total ankle replacement (TAR) and tibiotalar arthrodesis (TTA) are used in the surgical management of arthritis. Over past decade, TAR instrumentation, techniques, implants have improved, making procedure more reliable reproducible, thus common.The Nationwide Inpatient Sample database from 2007 to 2013 was obtain data on patients elder than 50 years who underwent either or TTA. Differences temporal, demographic, diagnosis trends between TTA were analyzed.Between 2013, 15,060 35,096...

Abstract The purpose of this study was to evaluate the viability human adipose‐derived stem cells (ADSCs) transduced with a lentiviral (LV) vector overexpress bone morphogenetic protein‐2 (BMP‐2) loaded onto novel 3D printed scaffold. Human ADSCs were LV carrying cDNA for BMP‐2. Hyperelastic “Bone” (HB) In vitro BMP‐2 production assessed using enzyme‐linked immunosorbent assay analysis. ability on HB scaffold induce in vivo formation hind limb muscle pouch model following groups: LV‐BMP‐2,...

Study Design Retrospective cohort study. Objectives To evaluate the complications of anterior lumbar interbody fusion (ALIF) in patients with primary hypercoagulable disorders and to compare outcomes between posterior spine fusions this patient population. Methods The PearlDiver national database was queried for who underwent ALIF. Primary endpoints included prevalence ALIF, incidence perioperative anticoagulation utilization, as well 30-day risks postoperative complications, readmissions,...

Retrospective cohort study. To determine the incidence and identify independent predictors of incisional hernia following anterior lumbar interbody fusion (ALIF). The PearlDiver national database was queried to patients who underwent ALIF. Patients were stratified based on presence or absence an diagnosis. Chi-squared Student's t-tests used demographic comorbidities between 2 cohorts. Multivariate logistic regression analysis performed risk factors for development. A total 165,110 ALIF...

Study Design Retrospective cohort analysis. Objective Identify demographic and clinical predictors for revision discectomy compare postoperative complications between primary microdiscectomy (MD) discectomy. Methods Patients who underwent one-level lumbar MD subsequent disc herniation were identified using the PearlDiver national database. Multivariate regression analysis was performed to identify of discectomy, assess 30-day opioid use, likelihood future fusion. Results Of 52,310 patients...

Study design. Retrospective cohort study Objective. To determine the incidence and identify risk factors for radiculopathy requiring treatment with oral glucocorticoids within one month following lumbar microdiscectomy. Summary of background data. Lumbar microdiscectomy (MD) often provides immediate relief low back leg pain; however, some patients experience recurrent postoperative radicular pain. While steroids are commonly used to manage this condition, frequency their use associated...

The purpose of this study is to examine the incidence nerve injury, clinical variables associated with palsy, and predictive factors laceration after gunshot wounds upper extremity.Forty-one patients from a level I trauma center extremity who underwent surgical exploration between 2007 2014 were identified retrospectively. Patients proximal ipsilateral injuries, inadequate documentation, imaging, or pre-existing neurologic deficit excluded. Patient demographics, sensory motor examination,...

Study Design. Retrospective database analysis. Objective. The aim of this study was to match risk factors for complications in patients who did and not sustain a dural tear while undergoing posterior lumbar spine surgery compare local systemic complications. Summary Background Data. Current data do adequately define whether the event sustaining an isolated increases postoperative controlling other confounding factors. Methods. PearlDiver Database queried underwent decompression and/or fusion...

Cadaveric study.To compare the position of femoral nerve within lumbar plexus at L4-L5 disc space in lateral decubitus vs prone position.Seven specimens were dissected and psoas muscle was identified marked with radiopaque paint. Lateral fluoroscopic images cadaveric obtained. The location normalized as a percentage L5 vertebral body (0% indicates posterior 100% anterior space). compared using paired t test.In position, located 28% anteriorly from edge space, relatively more posterior, 18%...

Purpose: The purpose of this study was to compare the efficacy simulation versus lecture-based education among preclinical medical students.Methods: Twenty students participated in randomized, controlled crossover study. Students were randomized four groups. Each group received two simulations and lectures covering different topics. administered a pre-test, post-test delayed post-test. mean percentage questions answered correctly on each test calculated. student's change score across three...

Abstract The objective of the present study was to assess ability transduced rat bone marrow cells (RBMCs) that overexpress BMP‐2 loaded on a three‐dimensionally (3D) printed scaffold heal critical sized femoral defect. Tricalcium phosphate (TCP) scaffolds were 3D fit RBMCs with lentiviral (LV) vector expressing or GFP. rats randomized into following treatment groups: (1) RBMC/LV‐BMP‐2 + TCP, (2) RBMC/LV‐GFP (3) nontransduced (4) TCP alone. animals euthanized at 12 weeks and evaluated plain...

Retrospective review of insurance database.To investigate national trends, complications, and costs after cervical disc replacement (CDR) using an administrative database representative the United States population.As CDR continues to be used treat patients with stenosis, it is important gain a better understanding its use on level, potential cost. This information will allow for optimal patient counseling, risk stratification, healthcare cost assessments. Several prior studies have...
