The adjunct use of descending neurogenic-evoked potentials when transcranial motor-evoked potentials degrade into warning criteria in pediatric spinal deformity surgery: minimizing false-positive events.

Purpose: This studies objective was to evaluate the utility of descending neurogenic-evoked potentials (DNEPs) in the setting of transcranial motor-evoked potentials (TCeMEPs) degradation into warning criteria during pediatric spinal deformity surgery.

Methods: An institutional spinal cord monitoring database was queried to identify all primary and revision pediatric spinal deformity cases, < / = 21 years of age performed from 1/2006 to 12/2021, in which TCeMEPs were the primary motor tract assessment modality which degraded into warning criteria, with subsequent initiation of adjunct DNEPs.

Results: Fourteen surgical cases (0.

Ogden Type I to III tibial tubercle fractures in skeletally immature patients: is routine anterior compartment fasciotomy of the leg indicated?

Purpose: Determine the frequency of compartment syndrome of the leg after displaced, operatively treated modified Ogden I to III tibial tubercle fractures (TTFxs), evaluate the preoperative assessment and use of advanced imaging, and need for prophylactic fasciotomies.

Methods: Retrospective analysis of operatively treated, displaced modified Ogden I to III TTFxs, at our level 1 paediatric trauma centre between 2007 and 2019. Modified Ogden Type IV and V fracture patterns were excluded.

Positive security screening episodes of patients with spinal implants are influenced by detector type and not implant material.

Background Context: Previous research on rates of spinal detection showed a low frequency of patients (5%) experienced delays and additional screening going through airport security. With continuous technology advances in screenings and the rise in cobalt chrome implantation, updated data on patient experiences was needed.

Purpose: 1) Assess the rates of detection and additional screening by traditional metal detectors and full body scanners in patients with metal spinal implants, 2) Compare the rates of detection of various metal types (Titanium and cobalt-chrome, titanium only, and stainless steel) STUDY DESIGN: Retrospective PATIENT SAMPLE: All spine surgical follow-ups over survey period.

Impact of Spinal Deformity Characteristics on Patient-reported Outcome Measurement Information System Scores in Patients With Idiopathic Scoliosis Undergoing Posterior Spinal Fusion.

Introduction: The impact of posterior spinal fusion (PSF) on physical function and pain and mental health in pediatric patients as quantified by the Patient-Reported Outcomes Measurement Information System (PROMIS), developed by the National Institute of Health, is largely unknown. The purpose of this study is to report the changes of PROMIS scores for upper extremity (UE), pain interference (PI), mobility (MOB), and peer relationships (PR) after PSF in patients with idiopathic scoliosis (IS), compare postoperative changes in PROMIS PI and Scoliosis Research Society-30 pain scores, and evaluate associations between curve characteristics and PROMIS scores.

Methods: A retrospective cohort of 122 patients (<18 years old) who underwent PSF for IS was identified through electronic medical record search.

Monteggia Fracture in an Extremely Preterm Infant with Biochemical Rickets: A Case Report.

Case: A preterm neonate with biochemical rickets is found to have a Monteggia fracture. The infant underwent percutaneous pinning. There was loss of fixation; however, the infant has been followed since discharge from the hospital and has completely healed with full range of motion.

Fracture Table Application for Pediatric Femur Fractures: Incidence and Risk Factors Associated With Adverse Outcomes.

Background: Flexible elastic nails, submuscular plating, and rigid locked intramedullary nails are common methods of fixation for pediatric femur fractures (PFF) in which the fracture table is used to aid reduction. Little is known about complications associated with fracture table application in PFF. The purpose of this study was to determine the incidence and risk factors associated with adverse outcomes related to fracture table application for the treatment of PFF.

Risk of Injury to Neurovascular Structures During Open Cerclage Wiring of the Femur: A Cadaveric Study.

The objective of this study was to examine the risk to the sciatic nerve and femoral artery during open passage of cerclage wires and to evaluate the safest techniques. After a standard lateral approach, cerclage passes along the femur were made in cadaveric specimens. Distance to the sciatic nerve and femoral artery was recorded.

Pediatric forearm fractures with in situ intramedullary implants.

Purpose: The purpose of this investigation is to present our institutional experience with fractures of the pediatric forearm with in situ intramedullary nails.

Methods: Six patients treated at our institution for forearm fracture with in situ intramedullary implants between 2004 and 2013 were reviewed. Patient demographics, injury and radiographic characteristics, method of treatment, time to union, and complications were collected from the medical record.

Platelets and plasma stimulate sheep rotator cuff tendon tenocytes when cultured in an extracellular matrix scaffold.

The addition of platelet-rich plasma (PRP) to rotator cuff repair has not translated into improved outcomes after surgery. However, recent work stimulating ligament healing has demonstrated improved outcomes when PRP or whole blood is combined with an extracellular matrix carrier. The objective of this study was to evaluate the effect of three components of blood (plasma, platelets, and macrophages) on the in vitro activity of ovine rotator cuff cells cultured in an extracellular matrix environment.

Exposed versus buried intramedullary implants for pediatric forearm fractures: a comparison of complications.

Background: The purpose of this study was to compare the rate of complications between buried and exposed intramedullary implants after fixation of pediatric forearm fractures.

Methods: A retrospective comparative cohort study of 339 children treated with intramedullary fixation for displaced forearm fractures between 2004 and 2009 was performed. Implants were left exposed in 128 patients (37.

Agrobacterium-mediated T-DNA transfer and integration into the chromosome of Streptomyces lividans.

Summary Agrobacterium tumefaciens is the prototype of a prokaryotic organism transmitting DNA across natural kingdom barriers into higher cells. In nature, a specific segment (T-DNA) of the resident Ti plasmid is transferred from this bacterium into plant cells and integrated into the plant cell genome. Expression of the integrated oncogenes contained in the T-DNA results in the tumour disease known as crown gall.
