I have what looks like two hairline fractures in my pinky finger based on x-rays. sustained while playing basketball. do i need to see an orthopedist?

Probably not: If they are just hairline fractures your primary care doctor can take care of that. Usually an orthopedist is only necessary if there is a displaced fracture where there is a complete break and poor alignment or if surgery is required to stabilize the fracture. Hairline fractures of the finger usually will heal fine with splinting.
