Equine heel bulb lacerations: 62 cases (2004-2018).

This research records and analyzes outcomes of 62 horses treated for heel bulb lacerations at a teaching hospital from 2004-2018. Findings suggest that horses with this type of wound have a good survival prognosis and a fair chance of returning to previous levels of work.

Study Overview

• The study looked into medical records from February 2004 to October 2018, and corresponding horse owners were interviewed for long-term outcomes.
• The study aimed to understand the correlation between various factors and the clinical outcome of horses with heel bulb wounds.

Participants

• The study involved 62 horses, evenly divided between mares and geldings.
• The horses varied in age, breed, and uses. The details of these variables were not mentioned in the abstract.

Wound Duration and Outcomes

• 36 horses had wounds that were 0 to 2 days old, and 17 horses had wounds older than 2 days.
• A striking observation was that horses with a wound of less than 2 days had a higher outcome score, indicating better recovery or survival rates.

Synovial Communication with the Wound

• In 21 out of the total 62 horses, synovial communication with the wound was observed, signifying that the wound had some connection with the synovial structures (joints and tendons).
• In 17 horses, one synovial structure was involved, while more than one structure was involved in 4 horses.
• However, the study did not find a significant correlation between the involvement of synovial structures and the clinical outcome.

Survival and Follow-up

• 59 horses survived and were discharged. However, follow-up information was available only for 30.5% (18 horses), potentially impacting the comprehensiveness of the data.
• 78% of the horses available for follow-up returned to their previous level of work.

Other Observations

• There were no other significant associations found with clinical outcome. Factors like degree of lameness at presentation, degree of wound contamination, prior treatment, and treatment with foot casting did not have a significant impact on the clinical outcome.
• The study concludes that despite the severity of heel bulb lacerations, horses show a good prognosis for survival and favorable chances of returning to work.
• The researchers suggest that additional findings need further investigation to establish their clinical relevance.
