Time-to-Surgery for Definitive Fixation of Hip Fractures: A Look at Outcomes Based Upon Delay.

The morbidity and mortality after hip fracture in the elderly are influenced by non-modifiable comorbidities. Time-to-surgery is a modifiable factor that may play a role in postoperative morbidity. This study investigates the outcomes and complications in the elderly hip fracture surgery as a function of time-to-surgery.

Quantitative Effect of Pelvic Position on Radiographic Assessment of Acetabular Component Position.

Background: Intraoperative fluoroscopy aims to improve component position in total hip arthroplasty. Measurement bias related to image quality, however, has not been quantified. We aim to quantify measurement bias in the interpretation of acetabular component position as a function of pelvis and fluoroscopic beam position in a simulated supine total hip arthroplasty model.

The relationship between the incidence of adhesive capsulitis and hemoglobin A.

Background: Previous studies have shown no correlation between adhesive capsulitis and hemoglobin A (HbA). However, HbA is only a measure of short-term blood sugar control. We created a previously nonvalidated variable, cumulative HbA, that uses HbA values over time to estimate the total disease burden a single individual experiences over a period.

Risk Factors for Postoperative Urinary Tract Infections in Patients Undergoing Total Joint Arthroplasty.

. Urinary tract infections (UTIs) are the most common minor complication following total joint arthroplasty (TJA) with incidence as high as 3.26%.

Latarjet Fixation: A Cadaveric Biomechanical Study Evaluating Cortical and Cannulated Screw Fixation.

Background: Attritional bone loss in patients with recurrent anterior instability has successfully been treated with a bone block procedure such as the Latarjet. It has not been previously demonstrated whether cortical or cancellous screws are superior when used for this procedure.

Purpose: To assess the strength of stainless steel cortical screws versus stainless steel cannulated cancellous screws in the Latarjet procedure.

Inter-Rater and Intra-Rater Repeatability and Reliability of EOS 3-Dimensional Imaging Analysis Software.

Background: Quantifying ideal component position for the acetabulum and stem during total hip arthroplasty (THA) has been described by many methods. A new imaging method using low-dose digital stereoradiography, the EOS imaging system, is a biplanar low-dose X-ray system that allows for 3-dimensional modeling of lower limbs and semiautomated measurement of pelvic parameters and implant alignment.

Methods: Twenty-five patients who underwent primary THA by a single surgeon between October 2014 and December 2014 were retrospectively selected.

Risk Prediction Tools for Hip and Knee Arthroplasty.

The current healthcare environment in America is driven by the concepts of quality, cost containment, and value. In this environment, primary hip and knee arthroplasty procedures have been targeted for cost containment through quality improvement initiatives intended to reduce the incidence of costly complications and readmissions. Accordingly, risk prediction tools have been developed in an attempt to quantify the patient-specific assessment of risk.

Perioperative Outcomes Following Unilateral Versus Bilateral Total Knee Arthroplasty.

Simultaneous bilateral total knee arthroplasty (SB-TKA) is potentially a cost saving manner of caring for patients with bilateral symptomatic knee arthritis. We performed a retrospective analysis using the 2010-2012 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to evaluate the risk of perioperative complication following SB-TKA. Demographic characteristics, comorbidities, and 30-day complication rates were studied using a propensity score-matched analysis comparing patients undergoing unilateral TKA and SB-TKA.

The Effect of BMI on 30 Day Outcomes Following Total Joint Arthroplasty.

Hip and knee arthroplasty (THA, TKA) are safe, effective procedures with reliable, reproducible outcomes. We aim to investigate obesity's effect on complications following arthroplasty surgery. Using the American College of Surgeons-National Surgical Quality Improvement Program database, 13,250 subjects were stratified into 5 groups based on BMI and matched for gender, age, surgery type and ASA class.

Femoral vein blood flow during a total hip arthroplasty using a modified Heuter approach.

Several modifications to traditional surgical approaches for total hip arthroplasty (THA) have been introduced in an attempt to improve upon minimally invasive approaches and enhance short-term recovery. However, minimally invasive approaches are not without risk, including that of postoperative venous thromboembolism (VTE). There has been no published literature evaluating the femoral vein during an anterior approach.

Factors Affecting Readmission Rates Following Primary Total Hip Arthroplasty.

Background: Readmissions following total hip arthroplasty are a focus given the forthcoming financial penalties that hospitals in the United States may incur starting in 2015. The purpose of this study was to identify both preoperative comorbidities and postoperative conditions that increase the risk of readmission following total hip arthroplasty.

Methods: Using the American College of Surgeons-National Surgical Quality Improvement Program data for 2011, a study population was identified using the Current Procedural Terminology code for primary total hip arthroplasty (27130).

Surgical Management of Symptomatic Olecranon Traction Spurs.

Background: There is a paucity of information pertaining to the pathoanatomy and treatment of symptomatic olecranon traction spurs.

Purpose: To describe the pathoanatomy of olecranon traction spur formation, a technique for spur resection, and a series of patients who failed conservative care and underwent operative treatment.

Study Design: Case series; Level of evidence, 4.

Prophylactic stabilization for bone metastases, myeloma, or lymphoma: do we need to protect the entire bone?

Background: The current operative standard of care for disseminated malignant bone disease suggests stabilizing the entire bone to avoid the need for subsequent operative intervention but risks of doing so include complications related to embolic phenomena.

Questions/purposes: We questioned whether progression and reoperation occur with enough frequency to justify additional risks of longer intramedullary devices.

Methods: A retrospective chart review was done for 96 patients with metastases, myeloma, or lymphoma who had undergone stabilization or arthroplasty of impending or actual femoral or humeral pathologic fractures using an approach favoring intramedullary fixation devices and long-stem arthroplasty.
