Arthrodesis of the pastern joint in the horse.

The research article investigates the effectiveness of five surgical techniques for arthrodesis of the pastern joint in horses. The authors found that the best results were achieved by first curetting the articular cartilage, then using lag screws or a T plate for fixation and compression, and finally immobilising the joint in a plaster cast.

Research Context and Methodology

• The study examined 16 horses, with six having a history of acute trauma and the remaining ten experiencing chronic lameness for a span of one to six months.
• Five different surgical techniques were employed on these horses to perform the arthrodesis of the pastern joint. These procedures were: curettage of the joint, lag screw compression, immobilisation in a plaster cast, compression using a T plate, and drilling.
• The surgery’s success was assessed based on clinical observations preoperatively and postoperatively, along with radiographical findings.

Research Findings

• The most effective surgical technique found in this study was a procedure that involved the use of luxation to curette the articular cartilage. This was followed by the application of either a T plate or lag screws for fixation and compression. Finally, the joint was immobilised by placing it within a plaster cast.
• The study did not provide detailed data regarding the outcomes of each surgical procedure. However, it indicated that this combination of procedures yielded the best results by providing optimal relief to the horse and facilitating faster and better recovery.

Implications and Conclusions

• The research findings suggest a potentially effective approach to treating horses experiencing chronic lameness or acute trauma in the pastern joint. The proposed surgical technique ensures proper immobilisation and significantly aids in the healing process.
• These findings may guide veterinary surgeons in understanding the optimal surgical techniques for these specific cases. However, more extensive studies and comparative research could further validate and substantiate the effectiveness of these procedures.
