Adjunctive Dorsal Spanning Plate Fixation in the Stabilization of Perilunate Dislocations.

Purpose: To compare the biomechanical properties of adjunctive dorsal spanning plate (DSP) fixation with traditional K-wire fixation of perilunate dislocations in a cadaveric model.

Methods: Fourteen fresh-frozen cadaveric wrists underwent simulated perilunate injury. The specimens were randomly allocated to either K-wire fixation versus K-wire and DSP fixation.
