Arthrocentesis of the temporomandibular joint in adult horses.

The research article aims to create a method for successfully performing arthrocentesis on the temporomandibular joint (TMJ) in adult horses. The paper suggests that the procedure is safe and effective, offering an improved ability to examine and treat TMJ in horses.

Methodology

In this research article, a combination of various techniques was used to develop a methodology for arthrocentesis of the TMJ. This involved:

• Studying 7 equine cadaver heads and 6 clinically normal adult horses.
• Using fluoroscopy, contrast radiography, and computed tomography on cadaver specimens to identify the TMJ and neighboring palpable landmarks.
• Developing a needle placement guide for accessing the joint along with detailed illustration of the regional anatomy.
• Testing the final arthrocentesis procedure created on 6 live adult horses to determine the method’s efficacy and safety.

Results

The study managed to successfully identify externally palpable landmarks significant for arthrocentesis. These structures comprised:

• The lateral border of the condylar process of the mandible.
• The zygomatic process of the temporal bone.
• The lateral pericapsular fat pad.

Moreover, the arthrocentesis was successfully conducted on all 6 joints in the living horses with these landmarks, with no complications documented during the procedure.

Conclusions

Overall, this research article suggests that the new technique identified has promising potential. It can improve the way the temporomandibular joint is examined and treated in horses, providing a high efficacy and safety rate. Veterinarians could use this procedure for diagnosis, relief of joint pain caused by inflammation, or other treatments related to TMJ conditions in horses.
