Mechanical Characteristics of Locking and Compression Plate Constructs Applied Dorsally to Distal Radius Fractures

Biomechanical Comparison of Double-Row Locking Plates Versus Single- and Double-Row Non-Locking Plates in a Comminuted Metacarpal Fracture Model

“…Locking plates have been shown to exhibit significantly greater stiffness and strength against both cyclic and non-cyclic loads compared with non-locking plates in comminuted fractures. 33,34 Locked plating has therefore been advocated as a minimally invasive approach for cases in which optimal reduction of a severely comminuted fracture is desired and preservation of the soft tissues is also important. 35,36 As discussed previously, both the quality of reduction and the maintenance of surrounding soft tissues are critical factors in determining the outcomes after internal fixation of metacarpal fractures.…”

Comparison Between Locking and Non-Locking Plates for Fixation of Metacarpal Fractures in an Animal Model

“…34 The current opinion in the treatment of comminuted distal radius fracture has shifted toward a preference for volar locking plate stabilization. 35 Early clinical outcomes have shown promising results using volar fixed-angle fixation techniques, with 80% to 90% good or excellent preliminary results using volar reduction and fixed-angle plate fixation for unstable, dorsally displaced distal radius fractures. 36 In our study, there is a limitation for the biomechanical testing method.…”

Ex Vivo Biomechanical Comparison of the 2.4 mm UniLOCK® Reconstruction Plate Using 2.4 mm Locking Versus Standard Screws for Fixation of Acetabular Osteotomy in Dogs

“…In contrast to our original hypotheses, we found no significant differences between repair techniques for anatomic reduction (assessed by joint congruity), osteotomy gap after cyclic loading (maintenance of primary and secondary reduction), or in the strength or stiffness of the constructs. Biomechanical testing comparing locking plate systems with traditional plating techniques have been performed in vitro on human cadaver models, 24,25,27,40–45 animal cadaver models, 34–36 and artificial models made from composite 26,37,46,47 . Some studies have shown no difference between standard and locked plating systems, 36,37,41–43,45 whereas others have shown biomechanical superiority of the locking system over traditional plating 40,44,46,47 especially when used in osteoporotic or simulated osteopenic bone models 24–27 .…”
