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 72 patients in 2 years. All arthrodesis sites were clinically and radiographically fused within 8 to 72 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
