Summary
# Editorial Summary: Musculoskeletal Injuries in Campdraft Horses Campdrafting, Australia's rapidly expanding cattle-handling sport, places distinct demands on the equine musculoskeletal system, yet its injury profile has remained undocumented until now. Brodie and Labens examined lameness records from 267 horses across two facilities over seven years, analysing signalment, clinical findings, diagnostic procedures, and final diagnoses to characterise the injury patterns specific to this discipline. Grade 2 lameness (mild, inconsistent at a trot) predominated in the cohort, with forelimb involvement more frequent (53%) than hindlimb (41%); notably, distal interphalangeal joint pathology accounted for nearly a quarter of all diagnoses, whilst metacarpal and metatarsal conditions represented 19%—a notably higher prevalence of distal forelimb disease than reported in other cow horse sports. Diagnostic anaesthesia proved efficient for localisation, with abaxial sesamoid nerve blocks most commonly positive, and two-thirds of cases reaching final diagnosis through anaesthesia combined with radiography alone, though ultrasonography was required in approximately one-quarter. For practitioners managing campdraft horses, this evidence suggests heightened vigilance for distal forelimb structures—particularly the coffin joint and metacarpus—and supports the use of targeted diagnostic anaesthesia as an effective first-line approach before committing to advanced imaging.

Practical Takeaways
- •When examining lame campdraft horses, expect distal forelimb pathology more frequently than in other equine disciplines; prioritize thorough distal limb assessment
- •Diagnostic anaesthesia combined with radiography is often sufficient for diagnosis (41% of cases); reserve ultrasonography for cases where imaging remains inconclusive
- •Bilateral forelimb lameness occurs in 13% of campdraft horses, suggesting the sport's demands may impose symmetrical loading stresses—evaluate both forelimbs even if one appears clinically worse
Key Findings
- •Distal interphalangeal joint lameness was most common (23%; 63/267 horses), followed by metacarpal/metatarsal injuries (19%; 53/267)
- •Forelimb lameness (53%) was more prevalent than hindlimb lameness (41%), with 13% bilateral forelimb cases
- •Diagnostic anaesthesia alone or combined with radiography/ultrasonography achieved diagnosis in 66% of cases (110/267 anaesthesia + radiography; 67 with all three modalities)
- •Abaxial sesamoid nerve block provided the most common positive response to diagnostic anaesthesia (22%; 43/187 horses)
