The Herbert cannulated bone screw in rearfoot arthrodesis

Herbert 4.5- and 6.5-mm. cannulated bone screws were used to fixate nine talocalcaneal and six talonavicular arthrodeses in 12 patients in 2 years. All arthrodesis sites were clinically and radiographically fused within 8 to 12 weeks of operation. The authors describe proper use of the Herbert cannulated bone screw and discuss its advantages and limitations, compared with those of the traditional lag screw in rearfoot arthrodesis.
