Ultrasound-assisted injection of the centrodistal joint in the horse.

Abstract: Injection of the centrodistal (CD) joint in the horse is a commonly performed procedure for both diagnostic and therapeutic purposes. This procedure can be technically challenging, and while radiographic guidance has been previously used, ultrasound localised injection of the CD joint has not been described. Objective: The purpose of this study was to explore the feasibility of using ultrasound localisation to increase the accuracy of CD joint injection. Methods: Experimental method assessment. Methods: One operator performed the ultrasound and injection of 24 CD joints in 12 sedated horses. The joints were injected with iohexol (2 ml), sterile saline (1.5 ml) and amikacin (0.5 ml). Dorsoplantar and dorsomedial plantarolateral radiographic projections were obtained immediately after injection to evaluate the presence of contrast material in the CD joint. Results: The CD joint was successfully injected in 17/24 joints, representing a 70.8% accuracy. Conclusions: The horses used in this study were from the University research herd, and not clinical cases. One investigator performed all the ultrasonography and CD joint injections. Conclusions: The use of ultrasound localisation could improve success of CD joint injection as well as improve the learning curve of less experienced practitioners learning this procedure.

The research article describes an investigation into the use of ultrasound to increase the accuracy of centrodistal (CD) joint injections in horses, which are often used therapeutically and diagnostically. The study found a 70.8% success rate in injecting the CD joint correctly using this method.

Objective and Purpose

  • The study set out to explore if the accuracy of CD joint injections could be increased using ultrasound localization. This could potentially make this common procedure in equine medical practice less technically challenging and more efficient.

Methodology

  • The research was an experimental method assessment performed by one operator who completed the ultrasound procedures and then proceeded to do the injections.
  • The sample comprised of 24 centrodistal joints sourced from 12 sedated horses.
  • The injection material sounded a combination of iohexol (2ml), saline (1.5ml), and amikacin (0.5ml).
  • The presence and location of the injected material were evaluated through radiographic projections obtained immediately post the injections.

Results

  • The data showed that the CD joint was successfully injected in 17 out of the 24 joints making the rate of successful injection 70.8% when using the ultrasound localisation method.

Conclusions

  • The horses used within the study were from a University research herd rather than clinical cases, hence limiting the variety of the sample set.
  • The ultrasound and CD joint injections were all performed by one operator which could introduce personal bias in the results.
  • Despite the above limitations, the study concluded that the use of ultrasound localisation could potentially improve the success of CD joint injections and aid less experienced practitioners in learning the procedure.
