Background And Purpose: Variations in hip anatomy limit the femoral canal fit of standard uncemented hip stems. In addition, there are still issues with leg length discrepancy and offset reconstruction, potentially resulting in impingement, dislocation, and wear. Modular stems with different shapes for femoral canal fit and multiple neck options may improve the outcome and reduce complications.

Faced with an aging population and the growing prevalence of heart disease, clinicians are seeking more effective ways to diagnose acute coronary syndromes rapidly and accurately. Emergency department physicians must make critical and time-sensitive decisions based on patient history, physical examination, and 12-lead electrocardiogram as justification for diagnosis of acute coronary syndromes.

On review of 4,749 paramedic run reports from a low-volume urban emergency medical services (EMS) system, 33 persons (0.69%) presented with RAF.

For the first part of the study, the two-dimensional geometry of the osteotomy plane was demonstrated in 25 CT-reconstructed femora after performing a virtual cut at a CCD angle of 135 degrees. In the second part, we constructed a prototype of an anatomic adapted trust-plate prosthesis (A-TPP) with an optimized trust-plate and corpus geometry based on the three-dimensional data of three human cadaveric femurs (age 67-75 years).
