Early Mobilization and Predictors of Delayed Disposition for Geriatric Hip Fractures.

Objectives: To evaluate the effect of perioperative variables including PT and walking distance on length of stay (LOS) in hip fracture patients.

Methods: Design: A retrospective review.

Setting: Single level I trauma center.

Predicting Instability Risk Following Hemiarthroplasty for Femoral Neck Hip Fractures in Geriatric Patients.

Background: Although a rare complication, dislocation following hemiarthroplasty (HA) for a femoral neck hip fracture is associated with increased mortality, readmission, and possible revision surgery. To date many of the specific risk factors have been difficult to demonstrate. Patient factors, surgical factors, as well as morphological factors need to be assessed.

Supra-acetabular Pin Placement Without Fluoroscopy in Anterior Pelvic External Fixation Application.

High-energy pelvic ring injuries are associated with a significant rate of mortality and may require urgent stabilization with anterior pelvic external fixation. The iliac crest can be used for pin placement, but supra-acetabular pin placement is biomechanically superior. Traditionally, supra-acetabular pin placement is performed in the operating room, with time-consuming imaging techniques.

Pelvic Ring Disruption During Childbirth: A Case Report.

Case: We present the management of a peripartum pelvic ring disruption. Initial conservative treatment failed; ultimately, open reduction with internal fixation was required. Four years later, the patient gave birth to another child by elective cesarean delivery.

Excessively long interfragmentary screws for posterior wall acetabular fractures can predict intra-articular penetration.

Background: The fixation of posterior wall acetabular fractures often utilizes interfragmentary screws with varying length. Intricate pelvic anatomy and overhanging greater trochanter make obtaining proper screw trajectory difficult. A large measurement may represent aberrant trajectory and breach of the articular surface.

Surface metrology of bone surface attachments of knee ligaments.

Objectives: Textural differences between entheses reflect biomechanical activities of the musculoskeletal system. Methods used to measure these surfaces have limitations. Here, the surface metrology of roughness of articular and entheseal surfaces of the knee are investigated with an optical profiler.

Unnecessary Preoperative Cardiology Evaluation and Transthoracic Echocardiogram Delays Time to Surgery for Geriatric Hip Fractures.

Objective: Delays to surgery for patients with geriatric hip fracture are associated with increased morbidity and mortality. The American Heart Association (AHA) and American College of Cardiology (ACC) Clinical Practice Guidelines (CPG) were created to standardize preoperative cardiology consultation and transthoracic echocardiogram (TTE). This study's purpose is to determine if these practices are over used and delay time to surgery at a safety net hospital.

Operating Room Traffic in Total Joint Arthroplasty: One Simple Measure Toward Solving a Complex Problem.

Background: Periprosthetic joint infection remains a devastating complication of total joint arthroplasty (TJA). The literature suggests that unnecessary operating room (OR) traffic increases the risk of surgical site infection by increasing bacterial load in the OR. We attempted to determine whether the posting of "restricted access" signs on the outside and inside of OR doors during primary TJA procedures would result in a reduction of OR door openings.

Ketamine intervention limits pathogen expansion in vitro.

Ketamine is one of several clinically important drugs whose therapeutic efficacy is due in part to their ability to act upon ion channels prevalent in nearly all biological systems. In studying eukaryotic and prokaryotic organisms in vitro, we show that ketamine short-circuits the growth and spatial expansion of three microorganisms, Stachybotrys chartarum, Staphylococcus epidermidis and Borrelia burgdorferi, at doses efficient at reducing depression-like behaviors in mouse models of clinical depression. Although our findings do not reveal the mechanism(s) by which ketamine mediates its antifungal and antibacterial effects, we hypothesize that a function of L-glutamate signal transduction is associated with the ability of ketamine to limit pathogen expansion.

Linking Brain Arteriovenous Malformations With Anorectal Hemorrhoids: A Clinical and Anatomical Review.

Patients who harbor brain arteriovenous malformations are at risk for intracranial hemorrhage. These malformations are often seen in inherited vascular diseases such as hereditary hemorrhagic telangiectasia. However, malformations within the brain also sporadically occur without a hereditary-coding component.

A case report of spinal dural arteriovenous fistula: origins, determinants, and consequences of abnormal vascular malformations.

A spinal dural arteriovenous fistula is an abnormally layered connection between radicular arteries and venous plexus of the spinal cord. This vascular condition is relatively rare with an incidence of 5-10 cases per million in the general population. Diagnosis of spinal dural arteriovenous fistula is differentiated by contrast-enhanced magnetic resonance angiography or structural magnetic resonance imaging, but a definitive diagnosis requires spinal angiography methods.

Peripheral Arteries May Be Reliable Indicators of Coronary Vascular Disease.

Atherosclerosis is a stronger predictor for ischemic cardiovascular events than traditional risk factors such as race, age, sex, history, and metabolic profile. Previous research had primarily used ultrasound; however, we performed a study using histopathology to more accurately grade atherosclerosis development using the American Heart Association's grading scale. We cross-sectioned 13 different arteries from 48 cadavers and placed them into three separate groups based on anatomic location: central arteries, peripheral arteries, and carotid arteries.

Laparoscopic Sleeve Gastrectomy Complicated by Portomesenteric Vein Thrombosis: a Case Series.

Background: Portomesenteric vein thrombosis (PMVT) is a rare, but potentially life-threatening, complication following laparoscopic sleeve gastrectomy (LSG).

Cases: Here, we discuss three cases of LSG complicated by the development of PMVT post-operatively. All patients presented within the first 20 days post-operatively with complaint of non-specific abdominal pain.
