Surgical treatment of distal tarsal joint luxations in three horses.

The research study discusses the clinical signs, diagnostic tests, surgical interventions, and outcomes of three horses effectively treated for dislocated distal tarsal joints. The authors report successful treatment via open reduction with internal fixation in two horses and closed reduction using a transfixation pin cast in the third horse.

Objective of the Study

• This study aims to document the clinical signs, diagnosis, surgical treatments, and post-operative outcomes for horses suffering from luxation, or dislocation, in the distal tarsal joints.

Clinical Signs and Diagnosis

• The research notes that two of the horses had luxations in the tarsometatarsal joints, while the third horse had luxation in the proximal intertarsal joint.
• Radiographic imaging was presumably used to diagnose these conditions, although the abstract does not detail the diagnostic process.

Surgical Treatments

• In two of the cases, open reduction was used. This procedure involves exposing the affected area with a surgical incision, followed by the repositioning (‘reduction’) of the dislocated bones.
• Furthermore, these two cases also underwent internal fixation — immobilizing the bone fragments to promote proper healing.
• In the third case, the researchers performed closed reduction using a transfixation pin cast. Closed reduction is a non-surgical procedure in which the bones are re-aligned without an incision. The pin cast then acts as a support structure to hold the bones in place during the recovery process.

Outcomes and Conclusions

• The treatments applied in all three cases resulted in satisfactory clinical outcomes, indicating a resolution of the luxation and, presumably, period of successful recovery.
• The study, thus, affirms that surgical treatments can effectively treat distal tarsal joint luxations in horses, contributing further evidence to this area of veterinary research.
