No single safe zone exists for the valgus cut angle to reproduce neutral mechanical alignment in the presence of femoral bowing in total knee arthroplasty.

Purpose: The aim of this study is to report the prevalence of femoral bowing in the Egyptian arthritic knees as a representative of the middle eastern population and to study the correlation between the femoral bowing and the degree of arthritis, varus deformity and the distal femoral valgus cut angle (VCA).

Methods: This is a single-center observational cross-sectional study. Out of 562 knees Scheduled for TKA, 124 knees were excluded leaving 438 knees eligible for the study.

CNS Demyelination Syndromes Following COVID-19 Vaccination: A Case Series.

Background And Objectives: Although immunization against coronavirus disease 2019 (COVID-19) is ongoing, adverse reactions to these vaccinations have been observed in isolated cases. We aimed to report different neurological complications developed after COVID-19 vaccination.

Materials And Methods: In our case series study, we report all cases of CNS demyelination following COVID-19 immunization.

Spontaneous Coronary Artery Dissection in Young Patients: A Case Series and Review of Current Management Algorithm.

Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognized non-atherosclerotic cause of acute coronary syndrome. Common risk factors for SCAD are coronary atherosclerosis, female gender, peripartum period, systemic inflammatory conditions, and connective tissue disorders. It manifests as myocardial ischemia and infarction, arrhythmia, and sudden cardiac death.

Left circumflex STEMI presenting as de Winter sign, an ECG Zebra that gives you the chills! A case report.

de Winter ECG sign is an anterior ST-segment elevation myocardial infarction equivalent, which refers to an occlusion of the proximal left anterior descending (LAD) coronary artery with tall T waves and the absence of ST elevations in the precordial leads on the electrocardiogram (ECG). This sign is often under-recognized and not treated as an ST-segment elevation myocardial infarction which can increase the morbidity and mortality of such a life-threatening condition. Here we report a characteristic de Winter ECG sign involving left circumflex artery as culprit vessel, which was managed with PCI.

Anomalous Origin of the Left Coronary Artery From the Right Coronary Cusp: A Case Report.

Anomalous origin of the left main coronary trunk from the right coronary sinus is a rare condition and is associated with a significantly increased risk of cardiac events, including sudden cardiac death, and it may pose difficulties in their management using revascularization strategies. We present a case of a 68-year-old man with worsening chest pain. Initial evaluation revealed ST elevation of the inferior wall leads and elevated troponins.
