Differences in perception of online anesthesiology between Thai medical students and teachers during the COVID-19 pandemic.

Purpose: Traditional anesthesiology learning was disrupted by the coronavirus disease 2019 pandemic and replaced by online learning. Students and teachers did not prepare well for this change. Determining the differences in perceptions can close the gap and develop more effective curricula.

Cadaveric study of the anatomical reference points for proximal humeral plate positioning.

Background: Complications following locking plate fixation in proximal humeral fractures often related to malposition plates and inadequate screw fixation. However, literature did not define the best anatomical reference point for plate positioning. We conducted a study to assess the occurrence of subacromial impingement and screw perforation with two anatomical reference points for proximal humeral plate positioning.
