Outcome of horses with synovial structure involvement following solar foot penetrations in four UK veterinary hospitals: 95 cases.

The research paper studies the influence of various factors on the outcome of horses with septic synovial structures caused by solar foot penetration. The study reveals that synovial involvement from foot penetration prognosis for survival and return to pre-injury athletic functionality is rather poor. Factors like central sulcus penetration, distal phalanx involvement, and delay in hospitalization contribute to these outcomes.

Research Methodology

• Data collection for the study was done retrospectively from four veterinary hospitals in the UK.
• An assessment of the factors and their outcomes was done using a questionnaire over the phone for follow-up data collection.
• Two multivariable logistic regression models were generated to better understand the impact of these factors on the outcome.
• Model 1 included all horses with synovial infection undergoing surgical treatment, with euthanasia during hospitalisation as the outcome variable.
• Model 2 included only horses that survived anaesthesia, with the failure to return to pre-injury athletic function as the outcome variable.

Findings of the Study

• The study included a total of 95 horses, out of which 56% survived for discharge, and only 36% could return to their pre-injury athletic functionality.
• Penetration of the central frog sulcus and concurrent distal phalanx involvement were found to significantly increase the odds of euthanasia during hospitalisation.
• The delay in hospitalisation was a significant factor affecting both euthanasia and return to pre-injury athletic function.
• The breed of the horse and the necessity of more than one surgery were also noted to affect their potential of returning to pre-injury functionality.

Conclusion

• The prognosis of horses surviving to discharge and returning to their pre-injury athletic function after a solar foot penetration with synovial involvement is guarded and poor respectively.
• The study identified penetration of the central sulcus of the frog, distal phalanx involvement, delayed referral and hospitalisation as major contributing factors to euthanasia during hospitalisation.
• Factors such as breed of the horse and the need for more than one surgery were connected to failure in returning to pre-injury athletic functionality.
• The findings of this research can greatly assist veterinary surgeons and horse owners in making more informed decisions regarding the management of such cases.
