Amputation of a finger as a primary procedure should be avoided unless the damage involves many tissues and is clearly irreparable. Even when a finger has been amputated by the injury, the possibility of reattachment should be considered (see below).
Ring avulsion is a special case. When a finger is caught by a ring, the soft tissues are sheared away from the underlying skeleton. Depending on the amount of damage, skin reattachment, microvascular reconstruction or even amputation may be required.

作为一个主要的手术应该避免手指截肢，除非损伤涉及到许多组织，而且明显是不可修复的。即使手指因受伤而截肢，也应考虑重新附着的可能性（见下文）。
环撕脱是一种特殊情况。当一个手指被戒指夹住时，软组织就会从下面的骨骼上被剪断。根据损伤程度，可能需要皮肤再附着、微血管重建甚至截肢。
