Summary
# Editorial Summary Severe hoof pain that fails to respond to conventional analgesia presents a significant clinical challenge, particularly when multiple pain mechanisms—inflammatory, neuropathic and post-traumatic—operate simultaneously. This case report introduces a modified composite pain score (MCPS) designed specifically for equine hoof pain assessment, demonstrating its application in a horse with acute subsolar seroma complicated by chronic laminitis, surgical infection and wound dehiscence. Where standard NSAIDs proved inadequate, a multimodal approach incorporating both anti-inflammatory agents (firocoxib, phenylbutazone, butorphanol, aspirin and fish oil) and neuropathic pain modulators (local and parenteral anaesthetics, pentoxifylline, ketamine and gabapentin) achieved meaningful pain control when guided by serial MCPS evaluations. The composite scoring system—which integrates observational behaviour, physiological indicators and interactive responses—proved more sensitive to therapeutic changes than single-modality assessment, enabling clinicians to tailor intervention to the specific pain phenotype present at each stage of recovery. For practitioners managing refractory hoof pain cases, this framework suggests that stratified pain assessment and targeted multimodal protocols may succeed where standard regimens fail, though broader validation across multiple cases would strengthen confidence in the MCPS as a clinical tool.

Practical Takeaways
- •When hoof pain doesn't respond to NSAIDs alone, evaluate for concurrent neuropathic pain and use multimodal protocols combining anti-inflammatory and neuropathic agents
- •Implement composite pain scoring (observational + physiological + interactive signs) to track treatment response more reliably than relying on single pain indicators
- •In severe hoof cases with wound complications, consider adding ketamine, gabapentin, or local anaesthetic blocks alongside traditional analgesia
Key Findings
- •Modified composite pain score (MCPS) combining observational, physiological, and interactive components demonstrated greater sensitivity for detecting pain response than single-modality assessment
- •Multimodal analgesia addressing both inflammatory and neuropathic pain states was necessary when NSAIDs alone proved refractory
- •Combined anti-inflammatory agents (firocoxib, butorphanol, phenylbutazone, aspirin, fish oil) with neuropathic modulators (ketamine, gabapentin, pentoxifylline, local anaesthetics) improved pain control in severe hoof pathology
