About this deal
The part may be removable from the mold without tearing or breaking the mold, in which case gently pull the casting out while pushing the mold away from it at the sides. Hopefully you used a mold release agent earlier, which should make this easier. You should then allow the filler to dry completely. This could take anywhere between 1 and 24 hours, depending on the brand and the area covered. Finger Plaster: A finger plaster cast is used to immobilize and protect a fractured or broken finger. It only covers the affected finger, allowing the patient's hand to move as needed. This cast is also often used for chronic conditions such as arthritis, tendonitis, and the trigger finger.
Keep your arm or leg raised on a soft surface, such as a pillow, for as long as possible in the first few days. This will help any swelling to go down.In the hand there are wrist bones (carpals), hand bones (metacarpals) and finger bones (phalanges). The fracture can be in the middle of the bone or can involve the joint where one bone meets and moves against another. The fracture can cause the bone to move out of position (a displaced fracture) or remain in its normal position (an un-displaced fracture). A fracture can be stable meaning that it is unlikely to move out of position or unstable where the fracture can move further. There are therefore a significant number of variations of hand fracture types.
