Objective: The aim of this study was to retrospectively evaluate the use, complications and outcomes of the Liberty Lock System (LLS) used to repair fractures in dogs and cats.

Methods: Medical records (October 2016-June 2019) of dog and cat fractures repaired with the LLS were reviewed. Data reviewed included signalment, fracture classification, complications and radiographic outcome.

Results: The LLS was used to repair 60 fractures (57 appendicular and 3 axial) in 54 dogs and 6 cats. Mean time to radiographic union was 6 weeks (range: 4-16). Radiographic union was achieved in all 60 fractures with 55/60 healing without recorded complications. Major complications 4/60 and minor complication 1/60 rates were low and no catastrophic complications occurred. The most common major complication was surgical site infection.

Conclusion: The LLS allowed for successful repair in all 60 cases with a wide variety of fractures. The LLS had a similar complication rate and time to radiographic union to that reported in other veterinary locking plate systems. The LLS is a reliable locking plate system which offers some advantages such as a low-profile plate with the ability to place non-polyaxial to angled polyaxial screws, to treat fractures in dogs and cats.
