Preoperative Predictors of Soft Tissue Releases Required for Femoral Exposure in Direct Anterior Total Hip Arthroplasty.

Background: Sequential soft tissue releases are utilized in direct anterior approach (DAA) total hip arthroplasty (THA) as incomplete femoral exposure may lead to complications. This study identifies patient-specific parameters associated with soft tissue releases required for femoral exposure.

Methods: A retrospective review was conducted on 133 patients (150 hips) who underwent primary THA via DAA with a single surgeon.

Antibiotic administration for open reduction internal fixation of closed ankle fractures: Is one preoperative dose enough?

Although preoperative antibiotics are used routinely in ankle fracture surgery, there is considerable variability in postoperative antibiotic dosing regimens amongst surgeons. The aim of this study is to compare the rate of surgical site infection (SSI) in patients receiving one dose of preoperative antibiotics to patients who received more than one dose of antibiotics. A single-center Level I Trauma Center retrospective review of patients with isolated closed ankle fractures who underwent open reduction internal fixation over a 10-year period was performed.

Editorial Commentary: Combined Anterior Cruciate Ligament/Medial Collateral Ligament Injuries: Surgeons Should Have a Low Threshold to Operate on the Medial Collateral Ligament.

Combined anterior cruciate ligament/medial collateral ligament (ACL/MCL) injuries are relatively common, and multiple factors are involved in surgical decision-making, particularly when it comes to the MCL. Historically, most surgeons treated the MCL conservatively and performed staged MCL reconstruction after MCL reconstruction only if there was persistent medial instability. This was followed by a nonoperative approach for the MCL (when reconstructing the ACL) unless there was evidence of extreme (grade III or >1 cm) valgus instability, valgus malalignment, or mid-substance or tibial-sided injury, avulsion, or Stener lesion.

Severe Lacerations in Alpine Ski Racing: A Case Series and Review of the Literature.

The Epidemiology of Necrotizing Fasciitis at a Rural Level 1 Trauma Center During the COVID-19 Pandemic.

Introduction: The impact of the COVID-19 pandemic on non-COVID-19 pathologies has been experienced worldwide. While people appropriately avoided social interactions, many also avoided essential medical care for acute and chronic conditions. This delay in seeking care has been associated with increased morbidity and mortality in several conditions, including life-threatening infections such as necrotizing fasciitis.

Association of Geometric Characteristics of Knee Anatomy (Alpha Angle and Intercondylar Notch Type) With Noncontact ACL Injury.

Background: The femoral intercondylar notch type and the alpha angle (the angle between the femoral notch roof and the long axis of the femur) are easily measured in clinical settings; however, their associations with anterior cruciate ligament (ACL) injury remain unclear.

Hypothesis/purpose: The purpose was to determine if the alpha angle and the femoral notch type are associated with noncontact ACL injury univariately and in combination with previously identified knee geometric risk factors. We hypothesized that the alpha angle and the femoral notch type are associated with noncontact ACL injury and that the association differs between men and women.

The Thyroid Hormone Receptor-RUNX2 Axis: A Novel Tumor Suppressive Pathway in Breast Cancer.

Metastatic breast cancer is refractory to conventional therapies and is an end-stage disease. RUNX2 is a transcription factor that becomes oncogenic when aberrantly expressed in multiple tumor types, including breast cancer, supporting tumor progression and metastases. Our previous work demonstrated that the thyroid hormone receptor beta (TRβ) inhibits RUNX2 expression and tumorigenic characteristics in thyroid cells.

Thyroid Hormone Receptor-β (TRβ) Mediates Runt-Related Transcription Factor 2 (Runx2) Expression in Thyroid Cancer Cells: A Novel Signaling Pathway in Thyroid Cancer.

Dysregulation of the thyroid hormone receptor (TR)β is common in human cancers. Restoration of functional TRβ delays tumor progression in models of thyroid and breast cancers implicating TRβ as a tumor suppressor. Conversely, aberrant expression of the runt-related transcription factor 2 (Runx2) is established in the progression and metastasis of thyroid, breast, and other cancers.

Guidelines reduce x-ray and blood gas utilization in acute asthma.

Using a retrospective chart review, we compared the use of chest radiography (CXR) and arterial blood gas testing (ABG) before (pre-P) and after (post-P) initiation of specific ordering guidelines for the use of these studies for patients presenting to the ED with acute asthma exacerbation. We noted the number of tests performed, the indication for the test, and the results when performed. There was a 55% reduction in the number of chest radiographs (85 of 213 patients pre-P had CXR as compared with 40 of 222 patients post-P, P <.

Compartment syndrome of the arm: a complication of noninvasive blood pressure monitoring during thrombolytic therapy for myocardial infarction.

We report a rare case of tricep compartment syndrome caused by a hematoma which resulted from noninvasive blood pressure monitoring (NIBPM) during thrombolytic therapy. Clinicians administering thrombolytic agents should be aware of the risk of bleeding and compartment syndrome at the site of NIBPM. Appropriate preventative measures should be instituted when using automated pneumatic cuffs.
