Abstract
An orthopedic traction apparatus includes in coaxial arrangement, a first tubular member anchored to a operating table or other stationary structure supporting a patient, and a second tubular member telescopically moving within the first one. A hand-crank and jack-screw mechanism is used to vary the position of the second member in relation to the first member. A tensiometer is provided at the distal end of the second member proximate a fixture adapted for attachment to a part of a patient's body. The tensiometer is based on a compressible, calibrated coil spring and is provided with a vernier scale for convenient and precise adjustment of the traction force. Alternately, the tensiometer uses a load-cell driving a digital read-out.
