A biomechanical comparison was conducted on two internal spinal fixation techniques: pins and Polymethylmethacrylate, and the String of Pearls Interlocking Plate System. Both techniques were applied to a surgically simulated level L7-S1 complete spinal injury, with the objective of the study being to compare the stability of the two techniques. Cadaver specimens from 18 skeletally mature large breed dogs were used. These specimens were randomly divided into two equal groups and fixated using one of the two internal spinal fixation techniques. The lumbosacral spine specimens (L5-S3) were subjected to a mechanically applied bending moment, which was applied to the caudal and cranial ends of the specimen. Biomechanical parameters including range of motion (RoM), neutral zone (NZ), and elastic zone stiffness (EZS) were used to compare the stability of the two fixation techniques. No significant difference between the means of the NZ in flexion (p-value=0.3458), extension (pvalue= 0.1255), and the total value (p-value = 0.3458) of the injured lumbosacral (L7-S1) joint fixated with the two fixation techniques was found. Similarly, no significant difference between the means of the RoM in flexion (p-value = 0.2386) and extension (p-value = 0.1255), or between the means of the EZS in extension (p-value = 0.4094) was noted. Therefore, it can be concluded that the stability of the injured joint between the two fixation techniques is similar. tm2016 Companion Animal Clinical Studies MSc Unrestricted 2016-10-14T07:33:30Z 2016-10-14T07:33:30Z 2016-09-02 2016 Dissertation Nel, JJ 2016, Canine lumbosacral fracture-luxation stabilised with the String of Pearls interlocking plate system or pins combined with polymethylmethacrylate : a biomechanical comparison, MSc Dissertation, University of Pretoria, Pretoria, viewed yymmdd <http://hdl.handle.net/2263/57300> S2016 http://hdl.handle.net/2263/57300 en © 2016 University of Pretoria.
