Summary

Outcomes for horses with digital flexor tendon lacerations varied by injury severity, with most surviving and many returning to work. Suturing lacerated tendons showed a slightly higher survival rate but didn't significantly impact long-term athletic use.

Area of Science:

  • Equine Sports Medicine

Background:

  • Digital flexor tendon injuries in horses are common and can significantly impact their athletic careers.
  • Understanding factors influencing the outcome of these injuries is crucial for effective treatment and prognosis.

Purpose of the Study:

  • To investigate the association between injury factors, treatment, and outcomes in horses with superficial or deep digital flexor muscle tendon lacerations.
  • To determine survival rates, return to original use, and soundness for riding after tendon injury.

Main Methods:

  • Retrospective review of medical records for 50 horses diagnosed with digital flexor tendon lacerations.
  • Data collected included age, injury type (transection vs. partial disruption), tendon sheath involvement, limb involvement, and treatment (sutured vs. not sutured).

  • Outcomes assessed included survival, return to original use, and soundness for riding at a median follow-up of 5 years.

    • Main Results:

    • Overall survival rate was high, with 39 out of 50 horses surviving beyond 1 year post-injury.
    • Horses with partial tendon disruptions had a higher survival rate (14/18) compared to those with complete transections (12/16 for one tendon, 13/16 for both).
    • Of the surviving horses, 27 returned to their original use and 32 were sound for riding; 9 horses with transected tendons were used athletically.
    • Suturing the lacerated tendons resulted in a survival rate of 15/16, while non-sutured tendons had a survival rate of 24/34.

    Conclusions:

    • Most horses with digital flexor tendon lacerations survive and can return to riding or their original use, regardless of limb or tendon sheath involvement.
    • While suturing showed a trend towards higher survival, it did not appear to significantly influence the likelihood of returning to athletic activities.
    • Injury severity (partial disruption vs. transection) was a more notable factor influencing outcomes than surgical intervention in this cohort.
