Summary
# Editorial Summary: Subsolar Abscesses—Treatment Duration and Complication Factors Despite subsolar abscesses representing one of the most prevalent causes of acute lameness in equine practice, robust epidemiological data on their management and outcomes remain scarce. Cole and colleagues retrospectively analysed 160 cases from a veterinary teaching hospital field service to identify factors influencing treatment duration, veterinary visit frequency, and complication rates. Summer-diagnosed abscesses required substantially longer treatment courses (9.4 times longer than other seasons), as did those located at the coronary band (3.2 times longer), whilst notably, horses presenting with severe lameness (grades 4–5) and those with established draining tracts healed significantly faster—suggesting that rapid, obvious drainage and severe pain presentation may facilitate more effective early intervention and drainage. Multi-digit involvement emerged as the primary risk factor for complications, whereas neither season nor location alone predicted increased veterinary visits. For practitioners managing subsolar abscesses, these findings underscore the importance of aggressive early drainage and suggest that coronary band cases warrant heightened vigilance for protracted healing; seasonal considerations may also inform prognosis discussions, particularly during summer months when extended treatment should be anticipated.

Practical Takeaways
- •Summer subsolar abscesses should be expected to require significantly longer treatment courses; plan client communication and follow-up accordingly
- •Coronary band location is a prognostic indicator of prolonged treatment; higher initial lameness grades and early drainage paradoxically predict faster resolution
- •Multi-digit involvement warrants cautious prognosis and closer monitoring for secondary complications
Key Findings
- •Summer-diagnosed abscesses required 9.42 times longer treatment duration than other seasons (P<0.001)
- •Abscesses at the coronary band required 3.21 times longer treatment than other locations (P<0.001)
- •Presence of a draining tract and higher lameness grades (3-5) at presentation were associated with shortened treatment times
- •Abscesses affecting multiple digit portions had increased risk of complications
