Delayed Onset Iliopsoas Tendonitis With Intramuscular Hematoma Following Total Hip Arthroplasty.

Iliopsoas tendonitis following total hip arthroplasty (THA) can be challenging to diagnose due to the many causes of postoperative groin pain. This case involves a 66-year-old female with right-sided hip and groin pain and a palpable mass, 3 years post-THA. Initial recovery was unremarkable until the sudden onset of symptoms after exercise.

Identifying Critical Evidence Gaps in Wound Closure and Incision Management After Total Knee Arthroplasty: Delphi Panel Insights.

Background: Effective surgical wound management in total knee arthroplasty (TKA) is crucial for optimal healing and patient outcomes. Despite surgical advances, managing wounds to prevent complications remains challenging. This study aimed to identify and address evidence gaps in TKA wound management, including preoperative optimization, intraoperative options, and postoperative complication avoidance.

Normative Values for Daily Functional Recovery Patterns Following Total Knee Arthroplasty.

Background: Wearable devices provide the ability for clinical teams to continuously monitor patients' rehabilitation progress with objective data. Understanding expected recovery patterns following total knee arthroplasty (TKA) enables prompt identification of patients failing to meet these milestones. The aim of this study was to establish normative values for daily functional recovery in the first 6 weeks after TKA using a wearable device.

Prevalence of disability secondary to work-related musculoskeletal injuries among orthopaedic surgeons.

Background: Orthopaedic surgeons encounter many work-place hazards that can lead to musculoskeletal injuries (MSI) and their clinical sequelae. This study aims to evaluate musculoskeletal injuries among orthopaedic surgeons and compare their rates of disability claims and time off work. Additionally, this study provides a perspective on the financial impact of work-related injuries among orthopaedic surgeons.

4-aminopyridine improves evoked potentials and ambulation in the taiep rat: A model of hypomyelination with atrophy of basal ganglia and cerebellum.

The taiep rat is a tubulin mutant with an early hypomyelination followed by progressive demyelination of the central nervous system due to a point mutation in the Tubb4a gene. It shows clinical, radiological, and pathological signs like those of the human leukodystrophy hypomyelination with atrophy of the basal ganglia and cerebellum (H-ABC). Taiep rats had tremor, ataxia, immobility episodes, epilepsy, and paralysis; the acronym of these signs given the name to this autosomal recessive trait.

Introduction: The aim of this study was to assess occupational injuries among female orthopaedic surgeons and compare these rates to their male counterparts.

Methods: An electronic survey was developed to assess occupational injuries among female orthopaedic surgeons. Descriptive statistics were analyzed for all survey items, and chi-squared tests and paired t-tests were used when appropriate.

Safe Zones and Trajectory of Femoral Pin Placement in Robotic Total Knee Arthroplasty.

Background: Robotic-assisted total knee arthroplasty may result in array pin-related complications. Lack of knowledge on ideal pin placement results in varied insertion sites and trajectory, with unknown risks to surrounding neurovascular structures.

Methods: This study included 10 lower-extremity magnetic resonance images.

Strategies to Increase the Spanish-Speaking Workforce in Orthopaedic Surgery within the United States.

Language-concordant care improves patient satisfaction. Given the increase in Spanish-speaking persons requiring orthopaedic care in the United States, it is essential to increase the Spanish-speaking workforce in orthopaedic surgery. We have proposed strategies to improve the proportion of Spanish-speaking orthopaedic surgeons in the U.

Current Trends and Future Directions for Outpatient Total Joint Arthroplasty: A Review of the Anesthesia Choices and Analgesic Options.

The aging population and the obesity epidemic have led to an increased rate of joint arthroplasty procedures, specifically total knee arthroplasty and total hip arthroplasty. These surgeries are associated with increased hospital length of stay and, consequently, higher costs. Despite the benefits of outpatient surgery, only a small percentage of total joint arthroplasties (TJAs) are done in this manner.

Increased Risk of In-Hospital Complications and Costs After Total Hip Arthroplasty for Primary and Secondary Osteonecrosis.

Background: An increasing proportion of patients are undergoing total hip arthroplasty (THA) for osteonecrosis (ON). Comorbid conditions and surgical risk factors are known to be greater in ON patients compared with patients who have osteoarthritis (OA) alone. The purpose of our study was to quantify the specific in-hospital complications and resource utilization associated with patients undergoing THA for ON versus OA.

Label-Free Non-Linear Optics for the Study of Tubulin-Dependent Defects in Central Myelin.

The satisfactory visualization of cytoskeletal components in the brain is challenging. The ubiquitous distribution of the networks of microtubules, microfilaments, and intermediate filaments in all the neural tissues, together with the variability in the outcomes of fluorescent protein fusion strategies and their limited applicability to dynamic studies of antibodies and drugs as chromophore vehicles, make classical optical approaches not as effective as for other proteins. When tubulin needs to be studied, the label-free generation of second harmonics is a very suitable option due to the non-centrosymmetric organization of the molecule.

Concurrent optical inspection to boost characterization of plastic cortical bone under mechanical deformation.

The simultaneous surface and internal measurements from a chemically modified cortical bovine bone suffering a plastic range deformation are presented. Since the bone is an anisotropic structure, its mechanical response could be modified if its organic or inorganic phases change. The latter could result in high plastic deformations, where the interferometrical signal from an optical analysis is easily de-correlated.

Prevalence and Spectrum of Occupational Injury Among Orthopaedic Surgeons: A Cross-Sectional Study.

Unlabelled: Orthopaedic surgeons are at increased risk for many occupational hazards, both physical and mental. The aim of this study was to evaluate a wide range of work-related injuries among orthopaedic surgeons in the United States.

Methods: An electronic survey was developed to assess both physical and mental occupational hazards among orthopaedic surgeons.

Relative frequency of avascular necrosis of the hip as indication for primary Total Hip Arthroplasty in the USA vs. India.

Introduction: Background: Primary total hip arthroplasty (THA) is performed for a variety of pathologies. Osteoarthritis (OA) is the most common indication for THA in the United States of America (USA). The study aims to establish the incidence of indications for THA in the USA as compared to India and to assess whether Avascular Necrosis (AVN) of the Hip is a more frequent indication for THA in India than in the USA.

Chronic Opioid Use Independently Increases Complications and Resource Utilization After Primary Total Joint Arthroplasty.

Background: Current literature suggests a link between the chronic use of opioids and musculoskeletal surgical complications. Given the current opioid epidemic, the need to elucidate the effects of chronic opioid use (OD) on patient outcomes and cost has become important. The purpose of this study was to determine if OD is an independent risk factor for inpatient postoperative complications and resource utilization after primary total joint arthroplasty.

Relative frequency of primary total hip arthroplasty for avascular necrosis in the United States as compared to a regional center: A data review.

Background: The relative frequencies of indications for primary total hip arthroplasty (THA) are not well-established. This study aims to establish the incidence of THA performed for Avascular Necrosis of the hip (AVN), as well as the other most common indications for THA in the United States, as compared to the incidences at a high-volume tertiary referral center in Miami, Florida. We hypothesize that the relative incidence of AVN and each other indication for THA will vary significantly between the United States as a whole and the tertiary referral center.
