Summary
# Locking Compression Plates in Equine Fracture Surgery: Clinical Outcomes and Applications Between 2004 and 2006, Levine and Richardson retrospectively analysed 31 equine cases treated with locking compression plates (LCPs) for fracture stabilisation or arthrodesis, including challenging presentations such as medial condylar fractures (n=5), metacarpophalangeal arthrodesis (n=8), and proximal interphalangeal arthrodesis (n=8). The theoretical advantage of LCP fixation—enhanced stability and reduced periosteal trauma compared with conventional plating—was evaluated against clinical outcomes following surgical intervention. Of the 27 horses that were discharged, 25 achieved soundness for intended purpose over a 6–25 month follow-up period, though notable complications emerged: incisional infection affected 32% of cases, implant infection 19%, implant loosening or breakage 22%, and contralateral limb laminitis 16%. For practitioners involved in equine orthopaedic cases, these data suggest LCPs are a viable option for fracture configurations requiring superior construct rigidity, particularly complex lateral condylar and olecranon fractures where conventional fixation may prove inadequate; however, the relatively high complication rate warrants careful case selection, meticulous surgical technique, and thorough owner counselling regarding post-operative management and infection risk.

Practical Takeaways
- •LCP is a viable surgical option for complex fractures and arthrodeses in horses when rigid fixation is needed for early post-operative comfort
- •Expect infection-related complications in approximately one-third of cases; careful post-operative management and monitoring are essential
- •Monitor for systemic complications including contralateral limb laminitis and colic, which collectively occurred in 22% of cases
Key Findings
- •27 of 31 horses (87%) were discharged from hospital following LCP-assisted fracture stabilisation or arthrodesis
- •25 of 31 horses (81%) achieved soundness for intended purpose at follow-up (6 weeks to 25 months)
- •Incisional infection (32%) and implant loosening/breakage (22%) were the most common complications
- •Contralateral limb laminitis occurred in 16% of cases, with 5 horses euthanised due to injury-related complications
