INTRODUCTION: Proximal humerus fractures (PHFs) are one of the most common fractures among patients aged 65 years and older, commonly due to low-energy mechanisms. It is essential to identify drivers of increased healthcare utilization in geriatric PHF patients and bring awareness to any disparities in care. Here, we identify factors associated with the likelihood of inpatient admission and prolonged hospital stay among patients aged 65 years and older who sustain PHF due to falls. METHODS: A national database was used to identify patients aged 65 years and older who suffered proximal humeral fractures due to a fall...

BACKGROUND: The management of elderly acetabular fractures is complex, with high rates of conversion total hip arthroplasty (THA) after open reduction and internal fixation (ORIF), but potentially higher rates of complications after acute THA. METHODS: The California Office of Statewide Health Planning and Development database was queried between 2010 and 2017 for all patients aged 60 years or older who sustained a closed, isolated acetabular fracture and underwent ORIF, THA, or a combination...

Medicare is the largest single purchaser of health care in the United States and currently helps to pay medical expenses for approximately one-fifth of the US population. The impetus for Medicare to move away from fee-for-service and toward value-based care payments reflects the need to incentivize and improve healthcare quality while containing increasing costs. This primer provides a detailed overview of several interrelated topics for an improved understanding of the Medicare program for orthopaedic surgeons, other clinicians, healthcare administrators, policymakers, and business leaders...

INTRODUCTION: For research to effectively guide clinical decision making, appropriate interpretation of data is paramount. The P-value is a useful tool for guiding the interpretation of data. However, despite its utility, the P-value is not without limitations. Of particular concern is the use of "trend statements" to describe non-statistically significant findings, a practice which introduces subjectivity and variability into data interpretation and can lead to the drawing of undue conclusions...

INTRODUCTION: Patients with myelopathy or radiculopathy commonly undergo anterior cervical fusion surgery (ACFS), which has a notable failure rate on occasion. The goal of this study was to compare revision and nonrevision surgery patients in cervical sagittal alignment (CSA) subsequent to ACFS; additionally, to identify the best CSA parameters for predicting clinical outcome after ACFS; and furthermore, to create an equation model to assist surgeons in making decisions on patients undergoing ACFS...

INTRODUCTION: Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective analgesics commonly used in fracture management. Although previously associated with delayed fracture healing, multiple studies have demonstrated their safety, with minimal risks of fracture healing. Given the current opioid crisis in the United States, alternate pain control modalities are essential to reduce opioid consumption. This study aims to determine whether the combination of oral acetaminophen and intravenous ketorolac is a viable alternative to opioid-based pain management in closed tibial shaft fractures treated with intramedullary nailing...

INTRODUCTION: Randomized controlled trials (RCTs) represent the highest level of evidence in orthopaedic surgery literature, although the robustness of statistical findings in these trials may be unreliable. We used the fragility index (FI), reverse fragility index (rFI), and fragility quotient (FQ) to evaluate the statistical stability of outcomes reported in RCTs that assess the use of tranexamic acid (TXA) across orthopaedic subspecialties. METHODS: PubMed, EMBASE, and MEDLINE were queried for RCTs (2010-present) reporting dichotomous outcomes with study groups stratified by TXA administration...

INTRODUCTION: Previous literature has reported minimal incidences of positive fungal/AFB cultures, questioning the routine use of these tests. With growing concern for excessive use, predictive factors for patients at higher risk for intraoperative AFB/fungal infections would help surgeons limit unnecessary testing. This study evaluates the positivity rate and predictive factors of positive fungal and/or acid-fast bacillus (AFB) cultures after primary, conversion, or revision hip and knee arthroplasty...

INTRODUCTION: Although the 5-factor modified frailty index (mFI-5) has been shown to be an independent predictor of complications after primary total hip arthroplasty (THA), its predictive value has not been evaluated in the setting of hip fracture. We therefore assessed the utility of mFI-5 score as an independent predictor of morbidity and mortality in patients who underwent THA or hemiarthroplasty for femoral neck fracture. METHODS: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients with femoral neck fractures treated with THA or hemiarthroplasty between 2006 and 2020...

Disability due to iliopsoas (IP) pain and dysfunction is underdiagnosed in the athletic population. The IP unit consists of the psoas major and iliacus muscles converging to form the IP tendon and is responsible primarily for hip flexion strength but has a number of secondary contributions such as femoral movement, trunk rotation, core stabilization, and dynamic anterior stability to the hip joint. As the IP passes in front of the anterior acetabulum and labrum, the diagnosis of IP pain may be confused with labral tearing seen on magnetic resonance imaging...

INTRODUCTION: Extra-articular juxtaphyseal fractures of the proximal phalanx are among the most common finger fractures in children. Immobilization of the digit for 3 to 4 weeks after reduction of the fracture is the current standard of care. The purpose of this retrospective study was to evaluate outcomes after intervention among pediatric proximal phalanx base fractures and establish radiographic criteria to guide management. METHODS: A multi-institutional retrospective review of skeletally immature patients treated for proximal phalanx juxtaphyseal fractures between 2002 and 2019 was conducted...

BACKGROUND: Preoperative planning for anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) is becoming increasingly common. While preoperative planning allows surgeons to determine individualized implant types, utilization of intraoperative navigation improves the accuracy of implant placement and may increase confidence in the preoperative plan. The purpose of this study was to evaluate and compare the rate at which surgeons use a glenoid implant different than their preoperative plan with and without the use of computer navigation...

INTRODUCTION: Vitamin D plays a critical role in bone health, affecting bone mineral density and fracture healing. Insufficient serum vitamin D levels are associated with increased fracture rates. Despite guidelines advocating vitamin D supplementation, little is known about the prescription rates after fragility fractures. This study aims to characterize vitamin D prescription rates after three common fragility fractures in patients older than 50 years and explore potential factors influencing prescription rates...

BACKGROUND: This study evaluates trends of cemented versus press-fit total knee arthroplasty (TKA). We hypothesized that press-fit TKA is more common in younger and obese patients. There may also be racial, geographic, and institutional variation. METHODS: The American Joint Replacement Registry was used to conduct a retrospective review of primary TKA procedures for osteoarthritis in the United States between January 2019 and March 2022. The objective was to identify differences in incidence, demographics, body mass index (BMI), Charlson Comorbidity Index (CCI), and institutional teaching status (teaching vs...

Skeletal dysplasias are a group of genetic conditions defined by atypical bone or cartilage growth and development. Skeletal abnormalities include short stature, limb deformity, joint contracture, and spinal deformity. Over 90% of disorders have a known genetic mutation that can definitively determine the diagnosis. As patients may present with a primary spinal concern, a careful clinical and radiographic evaluation can allow the physician to develop a working diagnosis to guide additional evaluation. Spinal manifestations include scoliosis and kyphoscoliosis, cervical instability, cervical kyphosis, thoracolumbar kyphosis, spinal stenosis, and atypical vertebral body morphology...

PURPOSE: The primary goal of this study was to determine the anatomic relationship between the clavicle and the apical lung segment. The secondary goal was to determine the incidence of pneumothorax (PTX) in patients who underwent clavicle ORIF to analyze the utility of postoperative chest radiographs. METHODS: Six hundred thirty-one patients with a midshaft clavicle fracture who underwent superior plating at a single institution were identified. Forty-two patients had a CT scan of the chest...

INTRODUCTION: Total joint arthroplasties (TJAs) have recently been shifting toward outpatient arthroplasty. This study aims to explore recent trends in outpatient total joint arthroplasty (TJA) procedures and examine whether patients with a higher comorbidity burden are undergoing outpatient arthroplasty. METHODS: Medicare fee-for-service claims were screened for patients who underwent total hip, knee, or shoulder arthroplasty procedures between January 2019 and December 2022...

BACKGROUND: The aging population has contributed to a rising incidence of acetabular fractures in older patients, yet current evidence guiding surgical treatment is limited by small sample sizes. This study used a nationwide database to investigate outcomes in older patients undergoing open reduction and internal fixation (ORIF) versus acute total hip arthroplasty (THA). METHODS: The PearlDiver database was queried for patients aged 60 years and older with an acute acetabular fracture who underwent ORIF or acute THA (2010 to 2021)...

INTRODUCTION: Workplace violence (WPV) in US health care is increasing, and many workers are likely to experience WPV during their careers. This study aims to assess the scope of WPV in orthopaedics. METHODS: A 20-item survey adopted from the World Health Organization's 'Workplace Violence in the Health Sector Country Case Studies Research Instruments Survey Questionnaire' was sent to Academy of Orthopaedic Surgeons members, including residents and fellows. Deidentified responses were collected electronically over a 1-month period and assessed...
