General Surgery is 5+ years (+ extra years in the lab if you should choose to do so, or are expected to do so). A Hand fellowship is generally 1 year although some will offer an extended "super fellowship" year for research or extra experience. If you then wanted to do a Sports Medicine fellowship you could, but it will NOT qualify you to do more ortho procedures. These fellowships are generally geared toward Family Practitioners and do not generally give you surgical experience other than simple reductions and in-office fracture management.
If you want to do Ortho, and not just Hand, you'll need to do an Ortho residency. However, at this point just concentrate on getting into medical school and doing the best you can; the rest will sort itself out (ie, you may be competitive for Ortho, if that's what you really want to do, gen Surg may become more or less competitive, etc.)
