ABSTRACT:
A collapsible femur traction device utilizes a segmented pole with an internal elastic cord running through the segments which will hold any desired number of the segments together to establish different effective lengths of the pole, so that the traction device can be used on small children as well as large adults, and is also collapsible into a very compact form. At the upper end of the pole, the segments are pulled apart and bent over double to achieve the proper length, with the adjacent ends of the pole inserted into a double socket which is attached to a strap on the upper thigh of the broken leg. A tensionable harness around the ankle applied traction to the leg by pulling it toward the opposite end of the pole, which extends beyond the foot.
