Background: Minimally invasive techniques such as percutaneous screw fixation have previously been shown to be mostly successful for pain relief and functional improvement in patients with pelvic metastases. In this study, we retrospectively reviewed the largest single-center cohort to date to further characterize the impact of this treatment on pain palliation, ambulation, and function; the predictors of suboptimal outcomes; and complications.

Methods: Electronic medical records were reviewed.

Purpose: In congenital scoliosis, the surgical strategy approach of hemivertebra excision, with or without instrumentation and fusion, is a common approach to correction of scoliosis. However, hemivertebra excisions are technically challenging, with potential complications including spinal cord injury, nerve root injury and cerebrospinal fluid leak. The purpose of this study was to determine whether correction of congenital scoliosis can be achieved using a posterior instrumentation/fusion-only approach without the need for hemivertebra excision.

Background: The incidence of primary reverse total shoulder arthroplasty (rTSA) and the prevalence of obesity have increased in the United States. Despite this, the literature assessing the effect of morbid obesity (body mass index≥40 kg/m) on perioperative surgical outcomes remains inconsistent.

Methods: A retrospective review of consecutive elective primary rTSA cases from January 2016 through September 2023 at a single tertiary referral center was performed.

Article Synopsis
  • The study is a retrospective cohort analysis comparing outcomes of posterior spinal fusion surgery in patients with Rett syndrome (RS) and cerebral palsy (CP) for neuromuscular scoliosis.
  • Results indicate that while complication rates are similar between RS and CP patients, those with CP experience higher estimated blood loss, longer surgical times, and worse postoperative spinal alignment.
  • Overall, findings suggest that RS patients have better surgical and postoperative outcomes compared to those with CP.

Background: Outcome selection is a critically important aspect of clinical trial design. Alive-and-ventilator free days is an outcome measure commonly used in critical care clinical trials, but has not been fully explored in resuscitation science.

Methods: A simulation study was performed to explore approaches to the definition and analysis of alive-and-ventilator free days in cardiac arrest populations.

Article Synopsis
  • The study's goal was to understand the reasons behind returns to the Emergency Department and readmissions within 90 days post-shoulder arthroplasty, aiming to alleviate financial burdens on healthcare systems.
  • A retrospective analysis was conducted on cases of anatomic and reverse shoulder arthroplasty from 2016 to 2023, collecting data on patient demographics, previous ED visits, and surgical information to identify predictors of post-operative complications.
  • Results indicated that factors such as prior ED visits, anxiety, surgical complications, and higher fragility scores significantly increased the likelihood of returning to the ED or being readmitted within 90 days after surgery.

Article Synopsis
  • Osteosarcoma is the most prevalent bone cancer in children, and new research targets specific molecular pathways to improve treatment outcomes through enhanced apoptosis and reduced tumor inflammation.
  • Using single-cell RNA sequencing, researchers found that a transgenic mouse model effectively mirrors the tumor characteristics and microenvironment seen in human osteosarcoma, highlighting the importance of specific gene knockouts in reducing T cell exhaustion and promoting interferon activation.
  • The study suggests mechanisms of tumor escape from treatment, such as gene overexpression and alternative pathways, providing insights that could lead to the development of innovative therapies for osteosarcoma.

Introduction: Initiation of Pavlik harness treatment for developmental dysplasia of the hip (DDH) by 6 to 7 weeks of age predicts a higher rate of success. Child Opportunity Index (COI) 2.0 is a single metric designed to measure resources and conditions affecting children's healthy development.

Article Synopsis
  • - The study analyzed 1,222 patient cases undergoing primary total hip arthroplasty (THA) to determine how specific medical conditions affect hospital costs, revealing a median total cost of $30,580 for the procedure.
  • - Key findings show that higher body mass index (BMI > 35), advanced American Society of Anesthesiologists (ASA) scores, and conditions like diabetes, congestive heart failure, and peripheral vascular disease significantly increase hospital costs associated with THA.
  • - The research concludes that patients with BMI > 35, peripheral vascular disease, chronic pulmonary disease, renal disease, and higher ASA scores incur greater inpatient costs during THA, mainly due to increased hospital room, board, and operating

Article Synopsis
  • A reliable test is essential for diagnosing infections, with histologic examination being a key method alongside tests like the CLO test and stool antigen test.
  • There can be occasional discrepancies between histopathology results and other diagnostic tests, which can impact clinical management.
  • This study analyzed pathology reports from gastric biopsies over five years to investigate reasons for discrepancies, focusing on cases where histology was negative but other tests were positive, finding that medication like proton pump inhibitors might have influenced the results.

Osteosarcoma(OS) is a highly aggressive bone cancer for which treatment has remained essentially unchanged for decades. Although OS is characterized by extensive genomic heterogeneity and instability, RB1 and TP53 have been shown to be the most commonly inactivated tumor suppressors in OS. We previously generated a mouse model with a double knockout (DKO) of Rb1 and Trp53 within cells of the osteoblastic lineage, which largely recapitulates human OS with nearly complete penetrance.

Introduction: Few current studies have examined loss to follow-up after rotator cuff-related shoulder arthroscopy. Understanding the demographic and surgical factors for missed follow-up would help identify patients most at risk and potentially mitigate the onset of complications while maximizing clinical outcomes.

Methods: A retrospective review of consecutive rotator cuff arthroscopic procedures with a minimum of 12-month follow-up done by a single, fellowship-trained surgeon was undertaken from February 2016 through January 2022.

Background/aims: Traditional manual methods of extracting anesthetic and physiological data from the electronic health record rely upon visual transcription by a human analyst that can be labor-intensive and prone to error. Technical complexity, relative inexperience in computer coding, and decreased access to data warehouses can deter investigators from obtaining valuable electronic health record data for research studies, especially in under-resourced settings. We therefore aimed to develop, pilot, and demonstrate the effectiveness and utility of a pragmatic data extraction methodology.

Interferon ɛ (IFNɛ) is a unique type I IFN that has been implicated in host defense against sexually transmitted infections. Zika virus (ZIKV), an emerging pathogen, can infect the female reproductive tract (FRT) and cause devastating diseases, particularly in pregnant women. How IFNɛ contributes to protection against ZIKV infection in vivo is unknown.

Introduction: The importance of consistent postoperative follow-up has been established for collecting patient-reported outcomes and surveilling for potential complications. Despite this, the prevalence of and risk factors for missed short-term follow-up after elective shoulder arthroplasty remain limited.

Methods: A retrospective review of consecutive primary anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty cases with a minimum of 12-month follow-up performed by a single, fellowship-trained shoulder surgeon was undertaken from January 2015 to December 2021.

Article Synopsis
  • This study examines the effectiveness of tension-band plating (TBP) in treating early-onset Blount disease, focusing on its impact on Langenskiöld stage (LS) and mechanical alignment outcomes over time.
  • A retrospective analysis of 16 children indicated that after TBP surgery, 84% of limbs showed improvement in LS, with a majority maintaining correct alignment years later.
  • Overall, results suggest that TBP significantly improves both the stage of Blount disease and the alignment of the limbs, highlighting its potential as an effective surgical option.
