Locking compression plates (LCP) may provide a useful alternative system to the commonly used stainless steel kerf-cut cylinders (KCC) currently used for fixation of cervical vertebrae in horses. The objectives of this study were to establish a method for biomechanical testing of equine C4-C5 articulations and to compare the biomechanical properties of cadaveric spines stabilised with KCC and LCP. Twenty-four equine cadaveric cervical spines were size measured from radiographs, and then randomly allocated to four groups. The C4-C5 articulation for each group was treated in the following way: group 1: KCC implanted, group 2: 8-hole 4.5/5.0 LCP implanted, group 3: 11-hole 3.5 LCP implanted and group 4: No implant. The specimens were fixed in resin and tested under four-point bending in ventral flexion until failure. Stiffness, maximum moment to failure and mode of failure were recorde...
