Summary
Septic digital tenosynovitis remains one of equine practice's most challenging conditions, with historically poor prognosis for athletic recovery. Smith and colleagues reviewed medical records and long-term outcomes from 90 horses treated for this condition, examining factors including age, sex, infection source, time to presentation, and discharge status, followed by telephone questionnaires to determine functional recovery. Whilst 87.8% of treated horses survived to hospital discharge, only early presentation within the first week of clinical signs significantly improved survival outcomes; critically, just 54.2% of the 72 horses with available follow-up data returned to their previous level of athletic function. This represents a substantial gap between initial survival and meaningful athletic recovery, highlighting that discharge from hospital should not be conflated with return to work. For equine professionals managing owners' expectations following treatment, these figures provide an evidence-based foundation for counselling on realistic long-term prognosis, whilst the clear impact of presentation timing reinforces the necessity of urgent veterinary intervention at the first sign of synovial involvement.

Practical Takeaways
- •While most horses (88%) survive septic digital tenosynovitis, only half will return to their previous athletic level—owners should be counselled accordingly about realistic prognosis
- •Early presentation (within 24 hours of onset) significantly improves survival rates, making rapid recognition and treatment critical for better outcomes
- •Post-discharge follow-up and realistic expectations regarding athletic return are essential parts of case management and client communication
Key Findings
- •87.8% (79/90) of horses with septic digital tenosynovitis survived to hospital discharge
- •Only 54.2% (39/72) of discharged horses returned to their previous level of athletic function on long-term follow-up
- •A delay of 1-7 days between onset of clinical signs and presentation for treatment significantly reduced the likelihood of survival to discharge
- •Approximately 50% of horses treated for septic digital tenosynovitis fail to return to previous athletic function despite resolution of synovial sepsis
