Abstract:
A traction and alignment comparison between the Sager® Emergency Traction Splint and the
Hare Traction Splint was made on a Cadaver with an exposed Intertrochanteric Femur
fracture. Malalignment was observed when the Hare Traction Splint was applied. Acceptable
alignment occurred with application of a Sager® Emergency Traction Splint.
Sager® Emergency Traction Splints’ provide countertraction against the Ischial Tuberosity medial
to the Shaft of the Femur — whereas Hare Traction Splints provided countertraction against
the Ischial Tuberosity below the Shaft of the Femur. Pressure up
against the Femur with the Hare mechanism creates pressure and
possible injury on the Sciatic Nerve and other intervening soft tissue
structures. This does not occur with Sager® Emergency Traction Splints.

Sager® Emergency Traction Splint in place
with 15lbs. of traction. Note alignment of
fracture occurs and pressure on critical
structures below the Femoral Shaft is absent.
