Joints, hand, and sports are the sweet life... those guys basically never work on weekends and have inpatients that move out of the hospital very quickly. Operations are generally pretty short, so you can operate into old age. 99% of sports and hand are exclusively outpatient. Hand is absurdly complicated and the surgeries are very delicate. They're called "hand weenies" for a reason... need to know a lot and stay on top of a complicated knowledge base. I'm not an ortho sports fan myself (too many primadonnas....), but if you like that field you can have a very fulfilling and varied career. The decision to operate or not is more complicated than the stereotypes lead you to believe.
Total joints are a blast... it is literally human carpentry. Your patients limp into the hospital with a walker/cane and are playing golf a month later. Also, there is an incredible amount of detail involved in joint replacement that physicians outside of orthopaedics don't understand. Lots of materials science, engineering principles, biomechanics at play. Plus, in a 15 minute clinic visit you can cover the orthopaedic problems in ~10 minutes then get to know your patients personally for the rest of the visit. The doctor-patient relationship is great, lots of very happy patients. Even in spine, which get a bad rap, the patients are often extremely grateful. I've seen cadua equina patients in tears because the doc restored their ability to walk, spinal stenosis patients donating large sums of money to the residency research fund because they're no longer in pain 24/7.
Lifestyles are more difficult in spine, trauma, tumor, and peds. But you can still manage ~50-ish hrs/wk with minimal weekends and call if you accept lower earnings. The general orthopaedist is alive and well outside of major metro areas -- you can operate on all parts of the body and later in your career focus on a niche like joints or sports.
Ortho is an awesome specialty but you have to endure a brutal residency. Ortho residency has you operating more than any other surgical specialty. I know some chiefs who were literally in the OR for 48 hrs straight when on county trauma rotations. Not for the faint of heart, the culture requires a level of machismo, but it's totally worth it IMO.
