This simple review serves to equip young orthopaedic surgeons with the fundamental personal financial concepts essential for making wise financial choices early in their careers. Prompt elimination of all high-interest consumer debt and devising a strategy to address student loans are crucial first steps in establishing the foundation for personal financial success. Progressing through training and entering practice bring about enhanced personal discretionary funds that are most effectively deployed through consistent budgeting and automated saving strategies. Malpractice, disability, and life insurances are keys to protecting current and future earnings as well as preventing financial catastrophe.
