Internal fixation of the distal radius. A comparative, experimental study.
In a comparative, experimental examination of 60 human cadaver radii, the stability of various, widely used internal fixation procedures of a distal radius fracture loco typico using a dorsal wedge was determined. The use of 2.5-mm Kirschner wires (K-wires) delivered a 10% greater stability than 1.8-mm K-wires. The 2.7-mm polylactide rods achieved a slightly greater stability than 1.8-mm K-wires under accurate pinning conditions. Polylactide rods (35 mm length, 2 mm diameter) and polyglycolide rods (60 mm length, 2 mm diameter) proved to be 20% less solid than 1.8-mm K-wires and almost 45% less than plate fixation. The short polylactide pins, however, did not have enough hold in the proximal cortical bone. The 2.7-mm polylactide rods (60 mm length) complied with the stability prerequisites necessary for comparable substitution for K-wires in distal radius fractures.
