Abstract
Biomechanical tests were performed to compare five different methods of posterior fixation of a Heinig wedge osteotomy for single stage correction of severe spinal kyphosis. These methods included standard systems such as Harrington compression rods, sublaminar wires, and L-rods as well as two prototype methods. Force/deflection measurements, failure loading, and cyclic loading demonstrated that the two prototype systems produced greater stability (less relative motion) at the osteotomy site and were less susceptible to loosening with cyclic loading.
