Biomechanical analysis of expert anesthesiologists and novice residents performing a simulated central venous access procedure.

Background: Central venous access (CVA) is a frequent procedure taught in medical residencies. However, since CVA is a high-risk procedure requiring a detailed teaching and learning process to ensure trainee proficiency, it is necessary to determine objective differences between the expert's and the novice's performance to guide novice practitioners during their training process. This study compares experts' and novices' biomechanical variables during a simulated CVA performance.

Arthroscopy-Assisted Latissimus Dorsi Transfer for Irreparable Subscapularis Tears.

Irreparable tears of the subscapularis (SS) tendon are difficult to manage and represent a challenge for the surgeon, especially in young and active patients. They are associated with a horizontal imbalance of the shoulder, causing pain and limitation of active internal rotation. Historically, the alternative for these patients has been transfer of the pectoralis major, with all its variations, total or partial, up or under the conjoint tendon.
