Lead exposure continues to be a significant public health problem. In addition acute toxicity, Pb has an extremely long half-life in bone. Individuals with past develop increased blood levels during periods of high bone turnover or resorption. is known affect osteoblasts, osteoclasts, and chondrocytes been associated osteoporosis. However, its effects on skeletal repair have not studied. We exposed C57/B6 mice various concentrations acetate their drinking water achieve environmentally...
Abstract To further understand the cellular and molecular mechanisms underlying cortical bone graft healing, we have developed a novel mouse femur model that permits quantitative analysis of structural healing. A 4 mm mid‐diaphyseal femoral segment was removed replaced by either immediate implantation fresh autograft, frozen, genetically identical isograft or frozen allograft from different strain mouse, which secured with 22‐gauge metal intramedullary pin. Healing evaluated radiology,...
Object. The authors evaluated the effects of pilot hole preparation technique on insertional torque and axial pullout resistance in osteoporotic thoracic lumbar vertebrae. Methods. Using a probe fluoroscopy, 102 pedicle screws were placed 51 dual-energy x-ray absorptiometry—proven levels. Screws inserted using same-size tapping, one-size-under or no-tapping technique. Insertional measured. Analysis variance, Fisher exact test, regression analysis performed. Same-size tapping decreased spine....
Abstract Purpose The aim of this study was to investigate whether developmental delay is a risk factor for postoperative complications following pediatric spinal fusion. Methods American College Surgeons National Surgical Quality Improvement Program Pediatric database queried retrospectively identify patients who had undergone fusions between 2016 and 2021. population divided into two distinct groups 1) Patients with 2) have no delay. T-tests continuous variables chi-square tests categorical...
Osteoporosis is often not recognized until one or more fractures occur, yet post-fracture screening remains uncommon. Orthopedic surgeons are well situated to address this care gap. Both a protocol-based approach and fracture liaison services (FLS) have been proposed. The present surveys assess orthopedists' attitudes these alternative models for addressing gap.Two digital were sent all orthopedic midlevel providers at large level 1 trauma center 1.5 years apart.Thirty-six of 47 survey...
Background: Osteoporosis is often undiagnosed until patients experience fragility fractures. Pelvic fractures are common but underappreciated sentinel Screening with a pelvic fracture for osteoporosis may provide an opportunity to initiate appropriate treatments such as anti-osteoporosis therapy prevent additional Methods: This retrospective cohort review examined the management of after at large tertiary care center without established secondary prevention program. Data were extracted from...
A case of epidural abscess and discitis following instrumented PLIF using a single carbon fiber interbody cage is presented.To describe previously unreported complication posterior lumbar fusion cage.Various complications have been reported with PLIF. These include graft migration, pseudarthrosis, implant subsidence, hemorrhage, incidental durotomy, arachnoiditis, transient or permanent neurologic deficits, persistence pain, wound infections. There are no cases refractory associated PLIF.A...
Objective The aim of the study was to compare trends and differences in preoperative prolonged postoperative opioid use following spinal cord stimulator (SCS) implantation determine factors associated with use. Methods A database private-payer insurance records queried identify patients who underwent a primary paddle lead SCS placement via laminectomy (CPT-C3655) from 2008–2015. Our resulting cohort stratified into those use, between 3- 6-month postoperation, without. Multivariate logistic...
We hypothesize that postoperative anemia will predict length of stay (LOS) for geriatric patients undergoing minimally invasive (MIS) lumbar spine fusions.Patients who underwent MIS lateral and transforaminal interbody fusion between January 2017 March 2018 at an academic tertiary care referral center were selected. Eighty-one included. The primary outcome variable was LOS, measured in days. predictors studied preoperative hemoglobin (Hgb), day 1 Hgb, nadir intraoperative Hgb decrement...
Dislocation of the sacrococcygeal joint is a rare injury from trauma to buttocks, most often falling backwards. Standard care for this has not been determined because it rare. Left untreated can cause coccydynia in long-term. Here we present case report describe treatment an anterior dislocation with closed manual reduction. A 13-year-old female presented emergency department buttock pain after slipping backwards down stairs. On X-ray coccyx was bayonette apposition distal sacrum and...
Although spinal cord stimulators (SCS) continue to gain acceptance as a viable nonpharmacologic option for the treatment of chronic back pain, recent trends are not well established. The aim this study was evaluate overall demographic and regional in paddle lead SCS placement determine if differences exist between private-payer Medicare beneficiaries.A retrospective review insurance records from 2007-2014 performed identify patients who underwent primary via laminectomy (CPT-63655). Each...
Osteoporosis remains an undertreated disease entity causing substantial morbidity and mortality. Proximal humerus fractures are a common sentinel fracture, providing opportunity to intervene with antiresorptive therapy before more subsequent occur. Despite the success of programs aimed improve postfracture osteoporosis recognition management, less than 30% patients presenting fragility fracture diagnosed or treated for nationally. Further elucidation diagnosis management following is...

Anterior cervical discectomy with fusion is an effective treatment for patients having radiculopathy and myelopathy. To reduce morbidity associated autograft taken from the iliac crest without sacrificing high rates, a novel technique that harvests bone vertebral body adjacent to operative disc space has been proposed. The effects of square round graft harvest techniques on mechanical stability osteopenic donor vertebrae are unknown. We analyzed biomechanical implications by subjecting...
