Left ring finger fracture. I m teacher!

Dear doctors Yesterday Eve my left ring finger got damaged in an accident. 1 stich was taken. And dressing been done. Yesterday. I take advice from  2 doctors. First said- surgery is must but movement will not be same . They will use wire. And they will do surgery in morning and release home in the evening . They will give  anesthesia to finger only. Second opinion was that Wait for healing of wound and then he will set fingers put light plaster then hard plaster and your bone will be joined . And movement depend later. In surgery there may be infection , wiring will not work. Nails will be used to join bones and same movement will decide later. So I need opinion, Surgery is must or join by natural way . If Only shape deformity is there in surgery and plaster. My view is that if proper movement is not possible than why to opt surgery. Shape deformation is not issue for me. If any major problem occur then only surgery  if my life style affect only. I m teacher
