Is it easier to be a orthopedic surgeon or neurosurgeon?

Relative: They both require tremendous perseverance and dedication. As far as easy vs difficult, it is relative to the person and how they feel towards studying and working on joints and bones vs. The brain and spinal cord. Generally, a neurosurgeon may have to do a year or so more training before they are a full blown "attending physician.".

Depends: On your interest in each and your surgical skill level. Both require medical school and a residency training. Neurosurgeons usually have a longer residency.

Neither: Neither is easy. If you dedicate yourself to becoming a physician, the rest will take care of itself.

Both are difficult: The best answer to your question is that these are both extremely difficult surgical subspecialties. They both take a minimum of 9 years of training after college and have very rigorous training programs and require huge knowledge bases and physical skills along with emotional and phycological strength to deal with the human impact of their jobs.

Specialties: They are both very rewarding specialties that require intense training. I don't believe it is harder to be one or the other. Many orthopedic surgeons sub specialize, which can take additional training.
