A Biomechanical Evaluation and Assessment of the Accuracy of Reduction of Two Methods of Acetabular Osteotomy Fixation in Dogs

Abstract

These findings support the use of the SWP technique as an alternative method of acetabular fracture repair.

Mechanical analysis of transversal iliac fracture stabilization using dynamic compression plate or screws and PMM in polyurethane bone model

“…However, the tests performed by other authors (Stubbs et al, 1998;Fitzpatrick et al, 2008;Bruce et al, 2014) yielded lower results, which can be explained by the use of synthetic bones in this study. The density of polyurethane lower than that of natural bone (O'Neill et al, 2012) and, therefore, the displacement results are lower when animal bones are used.…”

“…After the bending test, all specimens of group 2 displayed a breakdown of the PMM above the fracture site. Likewise, Stubbs et al (1998) reported the same results for the stabilization of the acetabulum using the same technique. Considering that the major complication of iliac fracture stabilization is the loosening of the screws, the PMM used around the screws worked as a locking system, thus preventing this complication (Burton, 2011).…”

“…The screw and the polymethylmethacrylate association has proven to be a good choice to treat iliac fractures (Burton, 2011), as well as in the treatment of acetabular fractures (Stubbs et al, 1998). The versatility of use has been the special feature reported (Stubbs et al, 1998;Burton, 2011).…”

“…The stabilization of acetabular fractures with screw and polymethylmethacrylate has been previously tested only on a biomechanical study by Stubbs et al (1998). The conclusion of this study was that compared to bone plates, this type of stabilization is easier to perform and ensures the same resistance.…”

Biomechanical Comparison of Two Plating Techniques for Fixation of Acetabular Osteotomies in Dogs

“…Implant failure can lead to malalignment of the fracture, osteoarthritis, and poor function. Because of technical difficulties associated with accuracy of reduction and complications with plating techniques, other methods of internal fixation have been used, including a tension‐band technique with screws and wire and strengthened with polymethylmethacrylate 11–13 …”
