Fracture-dislocation of proximal humerus in a young child: A case report.

Introduction: Proximal humerus Salter-Harris type II fractures combined with ipsilateral shoulder dislocation in children are extremely rare injuries. Therefore, the best prescribed treatment has not yet been established.

Case Presentation: A case of a 3-year-old boy who sustained an epiphyseal separation of the right proximal humerus (Salter-Harris type II) and an ipsilateral anterior dislocation of the glenohumeral joint following a road traffic accident.

Clinician Awareness of Patient-Reported Health-Related Social Needs: There's Room for Improvement.

Introduction: People experiencing health-related social needs (HRSNs), such as transportation insecurity, are less likely to undergo preventive health screenings. They are more likely to have worse health outcomes overall, including a higher rate of late-stage cancer diagnoses. If primary care clinicians are aware of HRSNs, they can tailor preventive care, including cancer screening approaches.

Factors in COVID-19 vaccine uptake in five racial/ethnic Colorado communities: A report from the Colorado CEAL project.

Purpose: To understand motivators, concerns, and factors associated with COVID-19 vaccine initiation for adults in five racial/ethnic communities across Colorado.

Methods: Community-based data collectors surveyed participants from five Colorado communities (urban and rural Latina/o/x, urban Black, rural African American immigrant, and urban American Indian) about vaccine attitudes, intentions, and uptake from September to December 2021. Bivariate and multivariable logistic regression models were used to examine factors associated with the primary outcome of COVID-19 vaccine "initiation.

Development of a finite element full spine model with active muscles for quantitatively analyzing sarcopenia effects on lumbar load.

Background And Objective: The musculoskeletal imbalance caused by disease is one of the most critical factors leading to spinal injuries, like sarcopenia. However, the effects of musculoskeletal imbalances on the spine are difficult to quantitatively investigate. Thus, a complete finite element spinal model was established to analyze the effects of musculoskeletal imbalance, especially concerning sarcopenia.

Using Administrative Billing Codes to Identify Acute Musculoskeletal Infections in Children.

Background And Objectives: Acute hematogenous musculoskeletal infections (MSKI) are medical emergencies with the potential for life-altering complications in afflicted children. Leveraging administrative data to study pediatric MSKI is difficult as many infections are chronic, nonhematogenous, or occur in children with significant comorbidities. The objective of this study was to validate a case-finding algorithm to accurately identify children hospitalized with acute hematogenous MSKI using administrative billing codes.

Patient control preferences for medical decision making before and after evaluation for left ventricular assist device.

Understanding patients' preferred roles in medical decision making (i.e., passive, collaborative, active) is important to personalized care and patient engagement.

COVID-19: A Comparative Study of Contagions Peaks in Cities from Europe and the Americas.

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by a group of viruses that provoke illnesses ranging from the common cold to more serious illnesses such as pneumonia. COVID-19 started in China and spread rapidly from a single city to an entire country in just 30 days and to the rest of the world in no more than 3 months. Several studies have tried to model the behavior of COVID-19 in diverse regions, based on differential equations of the SIR and stochastic SIR type, and their extensions.

Effect of a Patient Decision Aid on Preferences for Colorectal Cancer Screening Among Older Adults: A Secondary Analysis of a Randomized Clinical Trial.

Importance: Guidelines recommend individualized decision-making for colorectal cancer (CRC) screening among adults aged 76 to 84 years, a process that includes a consideration of health state and patient preference.

Objective: To determine whether a targeted patient decision aid would align older adults' screening preference with their potential to benefit from CRC screening.

Design, Setting, And Participants: This is a prespecified secondary analysis from a randomized clinical trial.

[Organization and risk management in stereotaxic body radiotherapy at the treatment station].

The development of stereotaxic body radiotherapy in the last decade has forced the radiotherapy departments to redouble their efforts in the fields of quality and risk management. For this purpose, increasingly complex and rigorous controls of high performance machines as well as a solid team training must be put in place. Extreme hypofractionation requires both increased vigilance at the treatment desk and well-defined and known procedures.

Complex bladder-exstrophy-epispadias management: causes of failure of initial bladder closure.

The success of the initial closure of the complex bladder-exstrophy remains a challenge in pediatric surgery. This study describes a personal experience of the causes of failure of the initial closure and operative morbidity during the surgical treatment of bladder-exstrophy complex. From April 2000 to March 2014, four patients aged 16 days to 7 years and 5 months underwent complex exstrophy-epispadias repair with pelvic osteotomies.

Anatomic tibial component design can increase tibial coverage and rotational alignment accuracy: a comparison of six contemporary designs.

Purpose: The aim of this study was to comprehensively evaluate contemporary tibial component designs against global tibial anatomy. We hypothesized that anatomically designed tibial components offer increased morphological fit to the resected proximal tibia with increased alignment accuracy compared to symmetric and asymmetric designs.

Methods: Using a multi-ethnic bone dataset, six contemporary tibial component designs were investigated, including anatomic, asymmetric, and symmetric design types.

Developing a physiotherapy-specific preliminary clinical decision-making tool for oxygen titration: a modified delphi study.

Purpose: To develop and evaluate a preliminary clinical decision-making tool (CDMT) to assist physiotherapists in titrating oxygen for acutely ill adults in Ontario.

Methods: A panel of 14 experienced cardiorespiratory physiotherapists was recruited. Factors relating to oxygen titration were identified using a modified Delphi technique.

Dilemma of high rate of conversion from knee arthroscopy to total knee arthroplasty.

We tried to reduce our rate of conversion from index knee arthroscopy to total knee arthroplasty (TKA) for degenerative pathology (primarily meniscal) in the setting of coexisting arthritis in patients 50 years or older. We hypothesized that, by using a 2-surgeon independent evaluation method, we could reduce the rate to less than 10% by 3-year follow-up. Forty-two consecutive patients were initially evaluated by the knee replacement surgeon to determine if they were TKA candidates.

Effect of total knee prosthesis design on patellar tracking and need for lateral retinacular release.

Intraoperative lateral retinacular release (LRR) during primary total knee arthroplasty (TKA) is discouraged, except when LRR is necessary to centralize patellofemoral tracking. This study compares the LRR rates in four designs of total knee implants and correlates how changes in prosthesis design affect LRR rates. 2881 primary TKAs performed by one surgeon using a single surgical technique were reviewed.

In vivo determination of total knee arthroplasty kinematics: a multicenter analysis of an asymmetrical posterior cruciate retaining total knee arthroplasty.

The objective of this study was to determine if consistent posterior femoral rollback of an asymmetrical posterior cruciate retaining (PCR) total knee arthroplasty was mostly influenced by the implant design, surgical technique, or presence of a well-functioning posterior cruciate ligament (PCL). Three-dimensional femorotibial kinematics was determined for 80 subjects implanted by 3 surgeons, and each subject was evaluated under fluoroscopic surveillance during a deep knee bend. All subjects in this present study having an intact PCL had a well-functioning PCR knee and experienced normal kinematic patterns, although less in magnitude than the normal knee.

Tibial component fixation in total knee arthroplasty: a comparison of pegged and stemmed designs.

This study compares midterm radiographic, functional, and quality-of-life outcomes in patients receiving a cemented tibial component that has either a short intramedullary stem or one that has a pegged tibial component. A cohort of 181 patients received 225 NexGen cruciate-retaining implants (84 stemmed, 141 pegged) during total knee arthroplasty, with annual follow-up examinations for up to 7 years. Both types of tibial components were associated with excellent radiographic and clinical results with no radiographic evidence of implant loosening or osteolysis.

The orthopedist as clinical densitometrist: cost- and time-effectiveness.

We tested the hypothesis that an orthopedic surgeon and his or her staff can efficiently and economically provide a bone densitometry service. This hypothesis reflects a philosophy that orthopedists should take a more active role in identifying patients at risk for osteoporosis. We evaluated the cost- and time-effectiveness of an orthopedic surgeon and his medical assistant in completing reports and related correspondence for dual-energy x-ray absorptiometry scans conducted in an orthopedic subspecialty clinic.

Cruciate-retaining total knee arthroplasty at 5 to 7 years followup.

Unlabelled: Cruciate-retaining total knee implants may improve postoperative function in total knee arthroplasty, but whether patients experience good restoration of kinematics, undue wear, or increased revision rates is debatable. I evaluated clinical results, radiographs, and survival rates of the NexGen posterior cruciate-retaining implant at 5-7 years followup in 251 knees (198 patients) in a prospective, consecutive total knee replacement series done from 1996-1997. A consistent improvement in knee scores and range of motion was observed from preoperative evaluation through 5 years followup.

Minimally invasive outpatient total hip arthroplasty: a financial analysis.

Unlabelled: Costs of outpatient total hip arthroplasties were compared with costs of a matched group of patients having inpatient total hip arthroplasties. Ten patients were in each group and had surgery by the same surgeon in the same hospital. The average hospital bill for the outpatients was $4000 less than for the inpatients.

Anterolateral mini-incision hip replacement surgery: a modified Watson-Jones approach.

Mini-incision total hip replacement seeks to eliminate some complications of traditional extensile exposure and also attempts to facilitate more rapid rehabilitation of patients after surgery. Different surgical approaches historically have been used to do hip replacement surgery. Anterior or anterolateral approaches have often been selected to decrease the risk of posterior dislocation.

In vivo determination of posterior femoral rollback for subjects having a NexGen posterior cruciate-retaining total knee arthroplasty.

This study determines the in vivo kinematics during a deep-knee bend activity for subjects implanted with a posterior cruciate-retaining total knee arthroplasty having asymmetric geometries. Of 20 subjects, 19 experienced posterior femoral rollback (PFR) of the lateral condyle (average -3.9 mm), and 13 subjects experienced PFR of the medial condyle (average -3.

Repair of transverse sternal nonunions using metal plates and autogenous bone graft.

Transverse sternal nonunion is a complication of sternal fracture or partial sternotomy, and requires surgical treatment. Three patients with repeated failure of standard sternal repair were treated with a technique using metal plates and autogenous bone graft, which resulted in bone union in all patients. Metal plating of the sternum, accompanied by autogenous bone graft, is an effective method of treating transverse sternal nonunion.
