Does Orthopaedic Resident Pelvis Fluoroscopy Knowledge improve with testing with a Novel Pelvis Model and Educational website?

Purpose: We tested whether residents would improve in fluoroscopy knowledge and ability after using an inexpensive novel pelvis model and educational website.

Methods: Twenty-four orthopaedic residents were recruited from three United States residency programs and randomised into two groups with equal numbers of juniors and seniors. The OrthoAcademy group received educational materials from a website ( www.

Percutaneous Screws for Column Support During Total Hip Reconstruction of Metastatic Disease of the Acetabulum.

Reconstruction of the hip joint in the setting of metastatic lesions of the acetabulum is particularly challenging and can carry significant morbidity for patients who are already medically frail. Novel techniques to minimize morbidity and optimize function warrant exploration for these patients. Here, we present a 50-year-old woman was unable to walk secondary to metastatic breast cancer involving the acetabulum with articular disruption.

Impacts of the Early COVID-19 Pandemic on Depressive Symptoms and Mental Health Among Student-Athletes.

Objective: Social distancing protocols due to the COVID-19 pandemic resulted in premature ending of athletic seasons and cancellation of upcoming seasons, placing significant stress on young athletes. Inability to play or forced early retirement has significant consequences on athlete's mental health, as demonstrated by an extensive body of injury literature. We hypothesize that premature suspension and cancellation of athletic events due to the COVID-19 pandemic leads to higher incidence of depressive symptoms among high-school and collegiate athletes.

An Epidemiologic Comparison of Injuries to Skiers and Snowboarders Treated at United States Emergency Departments, 2000-2019.

Skiing and snowboarding are popular competitive and recreational sports that can be associated with significant injury. Previous studies of skiing and snowboarding injuries have been conducted, but studies evaluating injury types and patterns over long periods of time are needed to drive effective injury prevention efforts. We hypothesized that injury patterns would differ among snowboarders and skiers and that the number of injuries remained constant over time.

Clinical Outcomes After ACL Reconstruction in Soccer (Football, Futbol) Players: A Systematic Review and Meta-Analysis.

Context: The risk factors for anterior cruciate ligament (ACL) tear for athletes participating in pivoting sports includes young age and female sex. A previous meta-analysis has reported a reinjury rate of 15% after ACL reconstruction (ACLR) for athletes across all sports. To the best of the authors' knowledge, this is the first systematic review and meta-analysis of available literature reporting outcomes after ACLR in soccer players.

The Senolytic Drug Fisetin Attenuates Bone Degeneration in the Progeria Mouse Model.

Aging leads to several geriatric conditions including osteoporosis (OP) and associated frailty syndrome. Treatments for these conditions are limited and none target fundamental drivers of pathology, and thus identifying strategies to delay progressive loss of tissue homeostasis and functional reserve will significantly improve quality of life in elderly individuals. A fundamental property of aging is the accumulation of senescent cells.

Venous thromboembolism prophylaxis with low molecular weight heparin versus unfractionated heparin for patients undergoing operative treatment of closed femoral shaft fractures.

Background: The objective of this study was to compare inpatient mortality rates for patients with operatively treated closed femoral shaft fractures (AO/OTA 32 A-C) who received venous thromboembolism (VTE) prophylaxis with either low molecular weight heparin (LMWH) or unfractionated heparin.

Methods: This was a retrospective cohort study of a national database of patients presenting to Level I through IV trauma centers in the United States. All patients ≥18 years of age who sustained an operatively treated closed femoral shaft fracture were included.

Fractures of the posterior malleolus: a systematic review and analysis of patient-reported outcome scale selection.

Purpose: Despite the extensive use of PROs in ankle fracture research, no study has quantified which PROs are most commonly used for assessing outcomes of patients who sustain fractures of the posterior malleolus. The purpose of this study was therefore to quantify which PROs are most commonly used for outcome research after posterior malleolus fractures.

Methods: A systematic search was performed using the preferred reporting items for systematic reviews and meta-analyses guidelines.

Extensor Tendon Injury After Volar Locking Plating for Distal Radius Fractures: A Systematic Review.

Distal radius fractures are common orthopedic injuries. Treatment has varied historically, but volar locking plating currently predominates. Although flexor tendon injury is a well-studied complication of this operation, extensor tendon injury is less well studied.

The intersection of fracture healing and infection: Orthopaedics research society workshop 2021.

Infection is a common cause of impaired fracture healing. In the clinical setting, definitive fracture treatment and infection are often treated separately and sequentially, by different clinical specialties. The ability to treat infection while promoting fracture healing will greatly reduce the cost, number of procedures, and patient morbidity associated with infected fractures.

The history of orthopaedic surgery in India: from antiquity to present.

Indian orthopedists have a legacy dating back more than 4000 years. Starting with the Harappan civilization, ancient orthopaedic surgeons reduced fractures and conducted therapeutic trepanations. Since then, Indian physicians have pioneered many of the orthopaedic techniques still used today - including the use of prosthetics, fracture tables, and rehabilitative physical therapy.

Revision Lateral Ankle Reconstruction 40 Years After Chrisman-Snook Procedure: A Case Report.

Case: A 70-year-old active woman presented with lateral ankle instability 40 years after a lateral ankle reconstruction procedure. Examination demonstrated gross instability, and advanced imaging revealed attenuation of her previous graft. She underwent anatomic reconstruction through a modified Brostrom-Gould technique and was able to return to hiking without pain.

Change in Heart Rate Variability after Concussion in a Collegiate Soccer Player.

Athletes are known to under-report concussion symptoms due to competitive disincentives to report and conflation of concussion symptoms with other conditions associated with rigorous participation in sports. A quantitative biomarker for concussion has the potential to decrease the reliance on inconsistent patient-reported symptoms for the diagnosis of concussion. The objective of this project was to monitor heart rate variability (HRV) patterns of in-season athletes as a potential biomarker for concussion.

Post-Traumatic Epilepsy after Sports-Related Concussion: A Case Report.

Sports-related concussions (SRCs) are a public health concern across the United States, and they lead to neurological sequelae that can last long after the event itself. Concussive convulsions at the time of injury are common and rarely require additional workup or treatment. Post-traumatic epilepsy (PTE), however, is a rare phenomenon that can develop after traumatic brain injury and must be managed with adequate medical therapy.

Return-to-Competition Criteria After Ulnar Collateral Ligament Reconstruction: A Systematic Review and Meta-analysis.

Background: Injury to the ulnar collateral ligament of the elbow is common among overhead throwing athletes and can result in significant functional limitations. While surgical reconstruction offers high rates of return to competition, there are no validated or universally accepted guidelines for determining when an athlete can safely resume play.

Purpose: To assess the existing scientific literature for return-to-competition criteria utilized after ulnar collateral ligament reconstruction.

Subfascial-located contraceptive devices requiring surgical removal.

Background: Subdermal etonogestrel implants are highly effective contraceptive methods. Despite standardization of insertion technique by the manufacturer, some implants are inadvertently placed too deeply within or below the plane of the biceps brachii fascia. Placement of these implants in a deep tissue plane results in more difficult removal, which is not always possible in the office setting.

The Efficacy of Arthroscopic Simulation Training on Clinical Ability: A Systematic Review.

Purpose: To examine the effect of arthroscopic simulator training on technical performance in a human model.

Methods: A systematic review was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Literature searches of PubMed, Embase, and Cochrane Library were conducted using combinations of the terms virtual, digital, computer, reality, simulation, arthroscopy, training, learning, and education.

Microvascular Anatomy and Intrinsic Gene Expression of Menisci From Young Adults.

Background: Meniscal vascular supply is an important determinant of its healing potential. It has been reported that only the peripheral 30% of the meniscus is vascularized in cadavers aged 53 to 94 years; however, the vascularity in young patients, in whom meniscal repair is more often performed, is unknown.

Purpose: The primary objective was to analyze and measure the microvascular anatomy of the meniscus in adult cadaveric specimens <35 years old.

Curriculum Reform and New Technology to Fill the Void of Musculoskeletal Education in Medical School Curriculum.

Musculoskeletal (MSK) disease comprises over 20% of all visits to healthcare providers each year, yet a disproportionately small percentage of medical school education focuses on MSK disease. Even among students applying into orthopaedic surgery, less than 50% demonstrate prerequisite anatomic knowledge before beginning their residency. Medical school curriculum reform is needed, given that only 15% have a required MSK curriculum.

The Life of a Fracture: Biologic Progression, Healing Gone Awry, and Evaluation of Union.

New knowledge about the molecular biology of fracture-healing provides opportunities for intervention and reduction of risk for specific phases that are affected by disease and medications. Modifiable and nonmodifiable risk factors can prolong healing, and the informed clinician should optimize each patient to provide the best chance for union. Techniques to monitor progression of fracture-healing have not changed substantially over time; new objective modalities are needed.

Congenital Unilateral Hypertrophy of the Foot Intrinsics: A Rare Case and Review of Literature.

Introduction: Congenital hypertrophy of the intrinsic muscles of the foot is a rare disorder of unknown incidence characterized by unilateral muscular hypertrophy of one or more of the intrinsic muscles. Few cases have been reported in literature, many presenting with hypertrophy of a single muscle.

Case Report: A 12-year-oldCaucasian female with hypertrophy of all intrinsic muscles of the right foot present since birth presented with muscle imbalance resulting in hammer toe deformities of the second and third toes with the second toe crossing over the hallux.

The Role of Complete Posterior Cruciate Ligament Release in Flexion Gap Balancing for Total Knee Arthroplasty.

Background: The sequence of posterior cruciate ligament (PCL) release in posterior-substituting designs, when performing gap balancing in total knee arthroplasty (TKA), is variable. We hypothesize that early complete PCL release during knee exposure will change the flexion balance to result in a uniform medial-lateral flexion gap symmetry at the time of implant placement.

Methods: Ten cadaveric knees were prepared for TKA using standard medial parapatellar approach.

Sports-related sternoclavicular joint injuries.

Sports-related injuries to the shoulder are common causes of disability. Injuries to the sternoclavicular joint (SCJ) in sports are more rare, though have been reported in a small number of cases. SCJ injury classification is determined by the degree of joint displacement and direction of clavicular displacement.
