Summary
# Carpal arthrodesis with locking compression plates: a viable salvage option Severe carpal pathology—whether acute fractures, chronic osteoarthritis, or angular limb deformities—presents significant surgical challenges, and this case series demonstrates that pancarpal and partial carpal arthrodesis using three locking compression plates (LCP) offers a practical solution for otherwise end-stage cases. Six horses aged 8 months to 16 years underwent the procedure, with autologous bone grafting incorporated in five cases to promote fusion, followed by external coaptation for 4–6 weeks postoperatively. All horses achieved complete radiographic arthrodesis and returned to pasture soundness within 4–5 months; notably, one animal requiring implant removal due to skin exposure still regained functional soundness post-removal. The three-plate configuration provides superior carpal stability whilst avoiding diaphyseal implant placement in the radius and third metacarpus—a considerable mechanical advantage over traditional approaches. For equine professionals managing chronic carpal disease refractory to conservative treatment, this technique represents a realistic salvage pathway that prioritises functional recovery rather than athletic performance, potentially extending the useful lives of affected horses.

Practical Takeaways
- •Pancarpal arthrodesis using 3 short locking compression plates is a viable surgical option for severe carpal instability and osteoarthritis, with good outcomes for pasture soundness
- •This technique avoids implant placement in the radius and metacarpal diaphysis, potentially reducing complications and allowing bone healing without compromising structural integrity
- •Plan for 4-6 months of external coaptation and radiographic monitoring post-surgery; implant removal may occasionally be necessary but doesn't necessarily compromise functional outcome
Key Findings
- •All 6 horses achieved complete arthrodesis and pasture soundness within 4-5 months postoperatively using 3 locking compression plates
- •Autologous cancellous bone grafting was used in 5 of 6 cases to support arthrodesis
- •One horse required implant removal at 6 months due to skin exposure but maintained pasture soundness after removal
- •Three short locking compression plates provided superior carpal stability without requiring diaphyseal implant placement
