Showcasing COVID-19: Just what the imaging tests present about the disease.
Although massive rotator cuff tears occasionally lead to severe impairment of shoulder function, the criteria for losing the ability to elevate the arm are unclear. This study aimed to analyze the features of both tear size and 3-dimensional (3D) shoulder kinematics that correspondto the loss of the ability to elevate the arm in patients with large and massive rotator cuff tears.

We prospectively enrolled patients with rotator cuff tears, including the supraspinatusand more than half of the subscapularis or more than two-thirds of the infraspinatus, without severe pain. A total of 13 patients (15 shoulders) were divided into 2 groups 9 shoulders in the pseudoparesis (P) group and 6 shoulders in the non-pseudoparesis (NP) group. Fluoroscopic images were collected during active scapular-plane elevation, and 3D shoulder kinematics was analyzed using 2-dimensional-3D registration techniques. The radiographic findings and 3D kinematic results were compared between the groups. The correlation between tear size erior translations of the humeral head, and posterior cuff tears may lead to loss of glenohumeral external rotation. With these abnormal kinematics, superior migration and loss of thoracohumeral external rotation were identified as features of pseudoparesis.
Anterior and posterior rotator cuff tears cause significant superior and anteroposterior translations of the humeral head, and posterior cuff tears may lead to loss of glenohumeral external rotation. With these abnormal kinematics, superior migration and loss of thoracohumeral external rotation were identified as features of pseudoparesis.
It is important to distinguish satisfaction regarding the outcome of care and satisfaction with the delivery of care. The Consumer Assessment of Healthcare Providers and Systems (CAHPS) surveys are modern assessments of hospitals and providers of delivery of care. The purpose of this study was to report inpatient satisfaction according to Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Clinician and Group Consumer Assessment of Healthcare Providers and Systems (CG-CAHPS) scores after shoulder arthroplasty and to determine factors that influence them, as well as their correlation with surgical expectations, pain perception, quality of life, surgical setting, and functional outcomes.

All patients scheduled for a shoulder arthroplasty were prospectively asked to complete a demographic and initial shoulder assessment form, a shoulder surgery expectations survey, a pain catastrophizing scale, the SF-12 (12-item Short Form) survey, and a resiliency form (Resilience Scale 11). Patiefore, may not be predictive of long-term functional outcomes.
Overall, 37 patients (74%) had CG-CAHPS scores that indicated satisfaction and 34 patients (68%) had HCAHPS scores that indicated satisfaction. Nonsmokers and patients discharged home after surgery report higher levels of inpatient hospital (HCAHPS) satisfaction after shoulder arthroplasty. Patients with high preoperative surgical expectations, pain perception, and resiliency are not generally more satisfied with the hospital or clinician. Preoperative diagnosis, location of surgery, and length of stay do not reliably impact satisfaction with the hospital or clinician. Inpatient HCAHPS and CG-CAHPS satisfaction does not correlate with legacy functional outcome measures and, therefore, may not be predictive of long-term functional outcomes.
Total shoulder arthroplasty (TSA) with second-generation Trabecular Metal™ implants (Zimmer, Warsaw, IN, USA) has shown good short-term outcomes. Differences in outcomes between cemented and uncemented fixation are unknown. This study compared the clinical, radiographic, and patient-rated outcomes of TSA with cemented vs. uncemented TM glenoids at minimum 5-year follow-up.

Patients who underwent anatomic TSA with second-generation TM glenoid components for primary osteoarthritis were identified for minimum 5-year follow-up. The patients were divided into 2 groups cemented and uncemented glenoid fixation. Outcome measures included implant survival, patient-rated outcomescores (Patient-Reported Outcomes Measurement Information System [PROMIS] and American Shoulder and Elbow Surgeons scores), shoulder range of motion, and radiographic analysis. Findings were compared between groups.

The study included 55 shoulders 27 in the cemented group (21 with full radiographic follow-up) and 28 in the uncemented groupcellent clinical and patient-reported outcomes with a 100% implant survival rate, regardless of cemented vs. uncemented fixation. LY3023414 cost However, the uncemented group showed a significantly higher rate of radiolucent lines and a higher frequency of mild metal debris. These radiographic findings did not affect the clinical outcomes, and their implications for long-term outcomes and prosthesis survival is unknown.Motorcycle to vehicle collision is one of the most common accidents in the world and usually leads to serious or fatal head injuries to motorcyclists. This study aims to investigate the influences of impact scenarios and vehicle front-end design parameters on head injury risk of the motorcyclist. Five general vehicle types and different impact scenarios were selected for a parametric analysis. Impact scenarios were set according to ISO, 13232 regulation considering impact angles and impact speeds. Five vehicle types of Sedan, MPV (Multi-Purpose Vehicle), SUV (Sport Utility Vehicle), EV (Electric Vehicle) and 1-Box vehicle were included. HIC15 (Head Injury Criterion), head angular acceleration and CSDM (Cumulative Strain Damage Measure) were calculated to evaluate head injury risk of the motorcyclist. The results show that the critical impact speed for HIC15 and head angular acceleration was around 15 m/s, while the critical speed for CSDM was approximately 10 m/s. Impact angle of 45° show extremely high injury risk to the motorcyclist head. Bonnet leading edge height and its combination with other parameter present high influences on motorcyclist head injuries, and the increasing the bonnet leading edge height can potentially reduce head injury risk of motorcyclists. In summary, the present research results provide some theoretic bases for determining the test speed in motorcycle-vehicle crash regulation and design consideration for typical vehicle front end shape.
