[{'content': "All of the following are used for giving skeletal traction, except - \nSelect and explain. \nA. Steimann's pin, B. Kirschner's wire, C. Bohler's stirrup, D. Rush pin", 'role': 'user'}, {'content': "Answer: D \nExplanation: Traction \n\nTraction is defined as a pulling force to treat muscle or skeletal disorders (fractures, dislocation). There are two\xa0major types of tractions: skin & skeletal traction.\n\nA) Skin traction\n\nHere the traction is applied to the skin (using adhesive or nonadhesive tape or straps) which is indirectly transmitted to the bone.\nSkin traction can sustain a pull of no more than 4 to 5 kgs.\n\n\n\nSkin traction is given by adhesive tape & bandage, Buck's apparatus.\nGallow's/Bryant's/Russel traction are examples of skin traction.\n\nB) Skeletal traction\n\nSkeletal traction is an invasive procedure in which pins, screws, wires or tongs (e.g., Steinmann pin, Denham's pin, Kirschner's wire, ice tong, Crutchfield's tong, Bohler stirrup, Ilizarov's wire) are placed into the bones so that the weight is directly applied to the bone.\n\nSkeletal traction is used.\n\nIn cases when the pulling force needed is more than the skin traction can bear.\nWhen longer durations of traction is required.\nWhen the part of the body needing traction is positioned so that the skin traction is impossible.\n\n\nUpto 20 kg weight is permitted.", 'role': 'assistant'}]
