Isolated Lateral Plating for Bicondylar Tibial Plateau Fractures: Factors Influencing Decision Making.

Lateral plating alone has been postulated as an alternative for fixation of bicondylar tibial plateau fractures in attempts to limit morbidity associated with dual plating. Characterization of fracture patterns that may facilitate lateral plating alone for bicondylar tibial plateau fractures is not well established. The authors analyzed radiographic and clinical outcomes of isolated lateral plating in patients with at least 6 months of follow-up.

Adolescent Idiopathic Scoliosis: Increased Body Mass Associated with Decreased Bracing Outcomes.

Bracing reduces the need for surgical intervention in patients with adolescent idiopathic scoliosis (AIS). However, bracing outcomes with variable body mass index (BMI) are understudied. The authors sought to determine the association of BMI with bracing outcomes.

Rate of Tibiotalocalcaneal (TTC) Fusion Using the Surgical Implant Generation Network (SIGN) Intramedullary Nail in Developing Countries.

Outcomes of the Surgical Implant Generation Network (SIGN) nail have been reported for femur and tibial fractures, but its use in tibiotalocalcaneal arthrodesis (TTCA) is not well studied. Radiographic and clinical outcomes of TTCA using the SIGN database in patients with > 6 months of radiographic follow up were analyzed. Rates of tibiotalar (TT) fusion and subtalar (ST) fusion at final follow up were assessed by two independent reviewers.

Preference Signaling Survey of Program Directors-After the Match.

Introduction: The 2022 to 2023 orthopaedic residency cycle implemented a preference signaling program (PSP), allowing applicants to send "signals" to up to 30 programs to demonstrate their genuine interest.

Methods: A 21-question survey was distributed to 98 PDs (32.

Consensus-Based Best Practice Guidelines for the Management of Spinal Deformity and Associated Tumors in Pediatric Neurofibromatosis Type 1: Screening and Surveillance, Surgical Intervention, and Medical Therapy.

Background: Spinal conditions, such as scoliosis and spinal tumors, are prevalent in neurofibromatosis type 1 (NF1). Despite the recognized importance of their early detection and treatment, there remain knowledge gaps in how to approach these manifestations. The purpose of this study was to utilize the experience of a multidisciplinary committee of experts to establish consensus-based best practice guidelines (BPGs) for spinal screening and surveillance, surgical intervention, and medical therapy in pediatric patients with NF1.

Grading the Severity of Damage to the Perijunctional Actomyosin Ring and Zonula Occludens-1 of the Corneal Endothelium by Ensemble Learning Methods.

In many epithelia, including the corneal endothelium, intracellular/extracellular stresses break down the perijunctional actomyosin ring (PAMR) and zonula occludens-1 (ZO-1) at the apical junctions. This study aims to grade the severity of damage to PAMR and ZO-1 through machine learning. Immunocytochemical images of PAMR and ZO-1 were drawn from recent studies on the corneal endothelium subjected to hypothermia and oxidative stress.

Professional Society Opportunities and Involvement for Early-Career Orthopaedic Surgeons.

Professional societies can provide orthopaedic surgeons opportunities to build strong fellowship among colleagues within a specialty, to gain leadership positions and responsibilities, and to contribute to the latest research and practice management guidelines. However, early-career surgeons often receive little to no guidance about how membership can benefit them in the long term. The primary purpose of this review article was to provide an overview of orthopaedic professional societies, why early-career orthopaedic surgeons should consider membership, and how they can get involved.

Compression Screw Fixation for Pediatric Olecranon Fractures.

Background: Pediatric olecranon fractures can be treated with several methods of fixation. Though postoperative outcomes of various fixation techniques, including cannulated intramedullary screws, have been described in adults, functional and radiographic outcomes of screw fixation in pediatric patients are unclear. In this study, we assessed clinical, radiographic, functional, and patient-reported outcomes of pediatric olecranon fractures treated with compression screw fixation.

Social Media Presence Is Associated With Diversity and Application Volume for Orthopedic Surgery Residency Programs.

The purpose of this study was to assess the association between social media presence (Twitter and Instagram), diversity in orthopedic surgery residency programs, and the number of applications received by a program. Data from Twitter and Instagram for 179 orthopedic residency programs accredited by the Accreditation Council for Graduate Medical Education were collected, including the presence of a social media account, date of first post, number of posts, and number of followers. Residency program data were collected from the Association of American Medical Colleges Residency Explorer Tool and included percentage of Whiteresidents, percentage of male residents, residency ranking, and number of applications submitted during the 2019 application cycle.

Hexokinase 1 cellular localization regulates the metabolic fate of glucose.

The product of hexokinase (HK) enzymes, glucose-6-phosphate, can be metabolized through glycolysis or directed to alternative metabolic routes, such as the pentose phosphate pathway (PPP) to generate anabolic intermediates. HK1 contains an N-terminal mitochondrial binding domain (MBD), but its physiologic significance remains unclear. To elucidate the effect of HK1 mitochondrial dissociation on cellular metabolism, we generated mice lacking the HK1 MBD (ΔE1HK1).

Scoliosis in Pediatric Patients With Acute Flaccid Myelitis.

Background: Acute flaccid myelitis (AFM) is an anterior horn disorder that manifests as rapid onset muscle weakness or paralysis. Development of scoliosis in pediatric AFM patients has been anecdotally reported, but associated risk factors or incidence have yet to be determined.

Methods: Pediatric AFM patients treated over a 10-year period at a tertiary care center were identified.

Spinal screening, malignancy, medical therapy, and surgical correction of deformity in pediatric patients with neurofibromatosis type 1: a systematic review.

The objective of this systematic review was to synthesize evidence regarding spinal screening recommendations, types of spinal and thoracic neurofibromatosis type 1 (NF1) tumors, medical therapy for NF1-associated neoplasms, and treatment with magnetically controlled growing rods (MCGRs) or cervical kyphosis correction in pediatric patients with NF1. We queried PubMed, Embase, Cochrane Library, Web of Science, Scopus, Clinicaltrials.gov, and medRxiv for studies reporting spinal screening recommendations, prognosis, and medical therapy for NF1-associated spinal tumors and MCGR use or cervical kyphosis correction in pediatric NF1 patients, yielding 758 publications, 33 of which were included.

Can magnetically controlled growing rods be successfully salvaged after deep surgical site infection?

Purpose: The purpose is to compare the rate of recurrent deep wound infection in patients who retained MCGRs versus those who underwent implant removal and exchange following index deep wound infection.

Methods: Using a multicenter registry, we identified patients with EOS who underwent surgical correction with MCGR. We defined deep SSI as any infection that required subsequent I&D and antibiotic therapy.

Study Design: Multicenter retrospective study.

Background: Recent studies have demonstrated diminishing returns in patients with early onset scoliosis (EOS) undergoing repeated lengthening of growing rods. Little is known about whether this same phenomenon occurs in patients with lax connective tissue disease (CTD).

Regional or Neuraxial Anesthesia May Help Mitigate the Effects of Bone Cement Implantation Syndrome in Patients Undergoing Cemented Hip and Knee Arthroplasty for Oncologic Indications.

Introduction: Bone cement implantation syndrome (BCIS) occurs during and after cementation of implants and is associated with hypotension, hypoxia, and cardiovascular collapse. In this study, we aimed to identify risk factors and potential mitigating factors of BCIS in the oncologic adult cohort undergoing cemented arthroplasty.

Methods: We retrospectively reviewed oncologic patients aged 18 years or older who underwent cemented arthroplasty of either the hip or knee from 2015 to 2020.
