Do i have to undergo surgery if i have scaphoid fracture non union in my hand? the fracture is already two years due.

Yes: I would definitely recommend surgery. If you opt not to, you will develop a scaphoid nonunion advanced collapse (snac) wrist. The salvage procedure for a snac wrist is less than desirable in terms of outcomes. If i were you, i'd have the scaphoid fixed with a structural tricortical autograft to prevent the sequela of the natural history of a scaphoid nonunion.

Scaphoid nonunion: Yes. If you want to avoid a slac (scapho-lunate advanced collapse) wrist and a subsequent wrist fusion. Scaphoid nonunion weakens the "keystone" of the carpals. This may result in collapse of the joint , deviation i the wrist radially, with radial degeneration. Trade a little surgery (scaphoid bone graft/orif) for wrist fusion (big surgery and a lot more stiffness). Believe me. Get the thing fixed.

You should: Not treating a scaphoid fracture nonunion may result in snac (scaphoid nonunion advanced collapse) wrist, a degenerative disorder analogous to arthritis. Even old fractures that can be treated (healed) successfully with surgery. The goal of treatment is to decrease the risk of developing arthritis. A more involved procedure may be required for treatment, should arthritis develop.

Scaphoid fracture: That is non unitted and old needs surgery to fix the fracture, it will not unite or heal by itiself, by casting or by other methods. However if the question is must someone have surgery..Well no , no one can say you must, but certainly most will very strongly recommend a younger person with a scaphoid non union to get it cared for with surgery to prevent later problems.
