Abstract

Objective To compare the accuracy of reduction and the biomechanical characteristics of canine acetabular osteotomies stabilized with locking versus standard screws in a locking plate. Study Design Ex vivo biomechanical study. Sample Population Cadaveric canine hemipelves and corresponding femurs (n=10 paired). Methods Transverse acetabular osteotomies stabilized with 5-hole 2.4 mm uniLOCK® reconstruction plates using either 2.4 mm locking monocortical or standard bicortical screw fixation (Synthes® Maxillofacial). Fracture reduction was assessed directly (craniocaudal acetabular width measurements and gross observation) and indirectly (impression casts). All constructs were fatigue-tested, followed by acute destructive testing. All outcome measures (mean±SD) were evaluated for significance (P® reconstruction plate.
