A retracting system especially for use with operating room equipment and adapted to permit a vinyl tube to be removed from a storage spool to a desired length. The spool system is then locked into position so that the tubing is not retracted. By pulling slightly on the tubing, the apparatus retracts the tubing onto the storage spool for future utilization.

Tubing retracting system

The present invention concerns a femoral hip prosthetic implant, and a process, that incorporates an interior channel in the implant, which channel permits the implant, after it is properly positioned in a canal at the proximal end of a prepared femur, to be left in that position. Cement is then injected through that channel and discharged through medial ports in the implant to flood and up-well in the space between the implant and the femoral canal, thereby bonding and sealing the implant to the proximal portion of the femur while the implant remains seated in the desired position within the femur. Preferably a collar is provided at the distal portion of the stem to firmly seat and center the stem within the femoral canal. Also, preferably a spacer is provided at the mid-portion of the stem to center the stem within the femoral canal and to prevent cement from passing down the femoral canal beyond the proximal end of the stem.
