Defining Posterior Wall Fragments in Associated Both Column Acetabular Fractures (OTA/AO 62C).

Objective: Associated both column acetabular fractures (OTA/AO 62C) with concomitant posterior wall fracture fragments (ABC + PW) have not been well-defined. The purpose of this study was to report on the incidence and morphology of ABC + PW fractures.

Methods: A retrospective review of associated both column (ABC) fractures between 2014 and 2020 was performed.

Prevalence of Vitamin D Deficiency in Patients With Charcot Arthropathy: A Single-Center Analysis.

Introduction: Vitamin D deficiency may be a potentially modifiable risk factor in patients with orthopaedic conditions including Charcot arthropathy. The purpose of this study was to determine the prevalence of vitamin D deficiency and insufficiency in patients with Charcot arthropathy.

Methods: All patients with Charcot arthropathy seen in our foot and ankle surgery clinic from January 2017 through June 2021 were screened for serum 25-hydroxyvitamin D levels.

Correlating Arthroscopic and Radiographic Findings of Deep Deltoid Ligament Injuries in Rotational Ankle Fractures.

Background: The deep deltoid ligament (DDL) is a key stabilizer to the medial ankle and ankle mortise and can be disrupted in ligamentous supination external rotation type IV (LSER4) ankle fractures. The purpose of this study was to define the medial clear space (MCS) measurement on injury mortise radiographs that corresponds with complete DDL injury.

Methods: A retrospective record review at a level 1 hospital was performed identifying patients with LSER4 ankle fractures who underwent arthroscopy and open reduction internal fixation.

Demographics and Epidemiology of Discoid Menisci of the Knee: Analysis of a Large Regional Insurance Database.

Background: A discoid meniscus is a morphological variant of normal knee joint meniscus shape and ultrastructure that can lead to traumatic tearing of this tissue and early joint osteoarthritis.

Purpose/hypothesis: The purpose of this study was to determine the prevalence of discoid menisci in a large, ethnically diverse regional cohort and to evaluate possible risk factors. The hypothesis was that there would be no difference in the epidemiological distribution of discoid menisci based on ethnicity or sex.

Current illicit drug use profile of orthopaedic trauma patients and its effect on hospital length of stay.

Introduction: The purpose of this study was to investigate the prevalence of illicit drug use among patients admitted with traumatic orthopaedic injuries and to determine its effect on hospital length of stay (LOS). We hypothesized that patients with pre-injury drug use would have a longer hospital LOS compared to those who do not use drugs.

Methods: We conducted a retrospective cohort study at our level 1 urban trauma center of patients admitted with traumatic orthopaedic injuries between 2013 and 2015 with urine toxicology screening.

Evaluation of the R2D2 protocol: A Novel Method for Assessing Emergency Department Disposition for Residents.

Background: The emergency department (ED) disposition and discharge process is a critical period in a patient's transition from an acute care setting to self-care or a bridge to other healthcare providers. The emergency physician plays a pivotal role in this process and is ultimately responsible for ensuring that patients are safely released from their care. We developed a protocol to guide residents through the ED discharge process using the mnemonic "R2D2": reassess the patient, recheck the workup, discuss the disposition plan with the attending, and finally discuss the discharge plan with the patient.

Remodeling of the tight junction during recovery from exposure to hydrogen peroxide in kidney epithelial cells.

Renal ischemia-reperfusion injury results in oxidative stress-induced alterations in barrier function. Activation of the mitogen-activated protein (MAP) kinase pathway during recovery from oxidative stress may be an effector of oxidant-induced tight junction reorganization. We hypothesized that tight junction composition and barrier function would be perturbed during recovery from oxidative stress.
