Limb position affects intraoperative assessment of condylar width.

Purpose: We sought to define how changes in position and rotation of fluoroscopic imaging may affect the assessment of condylar widening intraoperatively.

Methods: Thirty-three patients with tibial plateau fractures were prospectively identified and included in this study. Fluoroscopic images of the uninjured tibial plateau were obtained in (1) full extension and (2) slight flexion on foam ramp.

Characterizing Leadership Trends in Hand Surgery Fellowship Programs.

Purpose: The purpose of this study was to characterize academic and demographic factors most associated with fellowship director (FD) roles in hand surgery programs. A secondary aim was to characterize educational and employment trends. The final aim was to compare these findings with those in other orthopedic subspecialties.

Risk factors for loss to follow up of pelvis and acetabular fractures.

Introduction: Pelvic and acetabular fracture incidence is increasing worldwide for more than four decades. There is currently no evidence examining risk factors for loss to follow up in patients with these injuries.

Methods: Patients presenting with pelvic and/or acetabular fractures at our institution between 2015 and 2020 were included.

Outcomes in Pediatric Hip FAI Surgery: a Scoping Review.

Purpose Of Review: Femoracetabular impingement (FAI) is a common source of hip pain in children and adolescents. While nonoperative therapies and open surgical procedures can be effective, hip arthroscopy is a minimally invasive treatment option with substantial benefit. The purpose of this paper is to evaluate the current role of hip arthroscopy in treating FAI within the pediatric population.

Increased 30-Day Postoperative Readmission and Medical Complication Rates Among Patients 65 Years and Older Following Arthroscopic Rotator Cuff Repair.

Purpose: The purpose of this study is to use a large national database to assess short-term adverse events following arthroscopic rotator cuff repair in patients 65 years and older.

Methods: The ACS NSQIP database was queried to identify patients that underwent arthroscopic rotator cuff repair between December 31, 2015, and January 1, 2017. Patients were split into two groups: 1) between 40-65 years old and 2) 65+ years old.

Survey Analysis of Orthopedic Call Compensation.

We sought to determine the type, frequency, and compensation details of orthopedic call for orthopedic traumatologists. We administered a 24-question survey to all members of the Orthopaedic Trauma Association regarding the number and type of orthopedic surgeons within the call pool, frequency of call, number of hospitals covered, and compensation for weekday, weekend, holiday, and pediatric calls. A total of 105 orthopedic surgeons replied.

Primary versus revision total shoulder arthroplasty: comparing relative value and reimbursement trends.

Background: Total shoulder arthroplasty (TSA) has been demonstrated to be an effective treatment for multiple shoulder pathologies. The purpose of our study was to compare the relative value units (RVUs) per minute of surgical time for primary and revision TSA.

Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried to identify patients that underwent primary TSA, one-component revision TSA, and two-component revision TSA between January 1, 2015 and December 31, 2017 using current procedure terminology codes.

Treatment of tibial plateau fractures with a novel fenestrated screw system for delivery of bone graft substitute.

Purpose: The purpose of this study was to describe the incidence of subsidence in patients with AO/OTA 41 (tibial plateau) fractures which were repaired with a novel fenestrated screw system to used to deliver CaPO4 bone substitute material to fill the subchondral void and support the articular reduction.

Methods: Patients with unicondylar and bicondylar tibial plateau fractures were treated according to the usual technique of two surgeons. After fixation, the Zimmer Biomet N-Force Fixation System®, a fenestrated screw that allows for the injection of bone substitute was placed and used for injection of the proprietary calcium phosphate bone graft substitute into the subchondral void.

A Survey to Assess Agreement Between Pelvic Surgeons on the Outcome of Examination Under Anesthesia for Lateral Compression Pelvic Fractures.

Objectives: To assess agreement among pelvic surgeons regarding the interpretation of examination under anesthesia (EUA), the methodology by which EUA should be performed, and the definition of a positive examination.

Design: Survey.

Patients/participants: Ten patients who presented to our Level 1 trauma center with a pelvic ring injury were selected as clinical vignettes.

Effect of bariatric surgery on outcomes in the operative treatment of hip fractures.

Introduction: Few studies have evaluated the effect of prior bariatric surgery on outcomes following the operative treatment of hip fractures. The purpose of this study is to evaluate these metrics in a population of bariatric surgery patients compared to a control group who were operatively treated for hip fractures.

Materials And Methods: The California Office of Statewide Health Planning & Development (OSHPD) discharge database was accessed to identify patients who sustained a hip fracture between 2000-2014.

Characteristics of Marijuana Use Among Orthopedic Patients.

Marijuana use among orthopedic patients has not been extensively studied. The purpose of this study was to investigate the prevalence of marijuana use among orthopedic surgery patients. Additionally, the authors sought to better characterize how and why their patients use marijuana.

Exploratory Study of Heart Rate Variability and Sleep among Emergency Medical Services Shift Workers.

Objectives: To characterize the continuity and duration of sleep, and to measure nocturnal cardiac autonomic balance via heart rate variability (HRV) in a group of emergency medical technicians (EMTs) on and off duty.

Methods: Fourteen EMTs completed an online, daily sleep log that recorded total sleep duration, bedtime, rise time, and the number of alarms that caused awakening. HRV was captured using a physiological status monitor (PSM) affixed to a chest strap during sleep.

Scalable modulator for frequency shift keying in free space optical communications.

Frequency shift keyed (FSK) modulation formats are well-suited to deep space links and other high loss links. FSK's advantage comes from its use of bandwidth expansion. I.

781 Mbit/s photon-counting optical communications using a superconducting nanowire detector.

We demonstrate 1550 nm photon-counting optical communications with a NbN-nanowire superconducting single-photon detector. Source data are encoded with a rate-1/2 forward-error correcting code and transmitted by use of 32-ary pulse-position modulation at 5 and 10 GHz slot rates. Error-free performance is obtained with -0.
