Stump(redirected from stump up)
Also found in: Dictionary, Thesaurus, Medical, Legal, Idioms.
the part of an organ left after an amputation or operation (for example, stump of the stomach or uterus). The term is also applied to the remainder of a transected nerve or a removed appendix. It is most often used for the part left after the amputation of a limb.
After an amputation, some patients may have a false sensation (”phantom sensation”) of a nonexistent limb or part—for example, a hand or foot—or of pain in the limb (”phantom pains”). Diseases of the stump—such as wounds, fistulas, osteomyelitis, and eczema—require special treatment and sometimes a second amputation (reamputation). Defects of a stump that hinder the normal wearing of a prosthesis include too long or too short a stump, a conical stump, excess skin, contractures, and ankylosis. For a prosthesis to fit properly, the stump must be free of pain and have healthy skin and strong muscles, and the surviving joints must be able to move freely.
one of the basic tools in crayon drawing; it may also be used for drawings done in pencil, charcoal, or pastel. A stump is a short roll of paper or suede cut to a point and used to rub down the strokes of a drawing on paper, cardboard, or canvas. The tool produces shading effects.
