Conservative management of a transverse fracture of the distal phalanx in a Quarter Horse.

The research article describes the case of a 7-year-old Quarter Horse with a fractured bone in its leg that was treated using non-invasive methods, healed successfully, and was able to return to normal performance levels.

Clinical Evaluation

• The horse had been suffering from severe lameness in its left forelimb for 4 days. The precise location of the lameness was determined through clinical evaluation and diagnostic perineural analgesia, a technique used to numb specific nerves in order to identify the origin of pain. The lameness was found to be in the distal portion of the left forelimb.

Diagnostic Findings

• X-ray imaging was used for further diagnosis, which revealed a transverse fracture of the distal phalanx, the end bones of a horse’s limb, in the left forelimb.

Conservative Treatment

• Instead of opting for surgery, the horse was treated conservatively. Initial measures included allowing the horse to rest in a stall and stabilising the hoof with a cast made from fiberglass material and an elevated heel support.
• The horse showed significant improvement after these treatments, with the lameness notably reduced.

Recovery

• Over the following 4 months, the horse’s exercise regime was slowly escalated. The external support on the hoof was removed and the horse was progressively shod in a flat shoe.
• Six months post-injury, the horse was working at its normal, pre-injury performance level and didn’t exhibit lameness. Unfortunately, the horse had to be euthanized for unrelated reasons.

Posthumous evaluation

• Post-death, imaging with Magnetic Resonance (MR) and histological examination of the deceased horse’s limb confirmed the presence of tissue changes that are consistent with a healing transverse fracture.

Conclusion

• The case study suggests that conservative management can be an effective treatment strategy for transverse fractures of the distal phalanx. It allowed the horse to recover and return to its intended use.
