Mid-shaft transverse osteotomies were performed in 18 cadaveric metacarpals and randomly divided into two groups. Using dorsally applied plates for repair, one group was secured using 6mm unicortical screws, while bicortical screws were used in the second group. The metacarpals were tested to failure with a four-point bending protocol using a servo-hydraulic testing machine and a 1kN load cell. The mean load to failure was 596N (SD=142) for the unicortical and 541N (SD=171) for the bicortical group. The stiffness was 333N/mm (SD=116) for the unicortical and 458N/mm (SD=158) for the bicortical group. Both load to failure and stiffness were not statistically significant between the two groups. Failure occurred by fracture at the screw-bone interface in all specimens: no screw pull-out was observed. No biomechanical advantage was found when using bicortical screws in metacarpal fracture plating.

“…7,9 -11 Dorsal plating has been shown by several studies to produce a stronger construct than many other methods, including crossed K-wires, intraosseous wiring, multiple intramedullary K-wires, and simple lag screws. 2,[11][12][13] Standard AO, or the Association for the Study of Internal Fixation technique, uses a 6-hole single-row plate that is placed over the dorsal surface with 3 bicortical screws on either side of the fracture. Although the results of this method of fixation are good, complications such as tendon irritation, tendon rupture, finger stiffness, and the need for plate removal have been reported.…”

“…Plate and screw fixation has been shown to offer superior stability to most other methods such as crossed K-wires, intraosseous wiring, multiple intramedullary K-wires, and simple lag screws. 1,9,12,13 Standard AO technique involves use of a dorsally placed straight miniplate with 3 bicortical screws placed on either side of the fracture. 14 Newer plate designs allow for more screws to be placed in a shorter length of plate by using a double-row or staggered design.…”

“…5,9 -11 Several studies have demonstrated the superior stability of dorsal plate fixation over other methods, such as crossed K-wires, intraosseous wiring, multiple intramedullary K-wires, or simple lag screws. 1,9,12,13 Standard AO technique uses a single-row plate applied to the dorsal midline with 3 bicortical screws placed on either side of the fracture. 14 Good results have been achieved with this technique.…”
