I got 5thmetacarpal base hairline fracture, im using splint, my two fingers are tapped is it enough for in this frcture.suggest me?

Fracture care: If it is truly a hairline fracture, which means an incomplete fracture, then yes. As long as you also refrain from any stressful activities with the hand. It will take approximately 6-8 weeks to heal under normal circumstances.

Cast or splint: "dealers choice" a splint lets you take it off and wash but complicance is often an issue even with the best intentions and it may take longer to heal. While annoying at times a cast may work faster initially. For some but nondisplaced fractures dont mandate casting always ten weeks down the line no difference, just your experience in getting there.
