Objective To report arthroscopic osteochondral fragment removal from the equine cervical spine articular process joints (APJs) including long-term follow-up.
Study Design Case series.
Animals Three Warmblood horses with forelimb lameness and/or reduced range of motion of the cervical spine with osteochondral fragments between the cervical vertebrae C5/C6 or C6/C7.
Method Arthroscopy of the APJs of C5/C6 and C6/C7 was performed under general anesthesia. Following endoscopic evaluation of the joints, osteochondral fragments were removed using a rongeur.
Results All horses recovered from anesthesia with no anesthetic or minor postanesthetic complications. One horse needed a second procedure for fragment removal. Fourteen to 31 months post-surgery the horses were sound for their intended use and neurological examination revealed no abnormalities.
Conclusion Arthroscopic removal of osteochondral fragments can be performed safely in the equine cervical APJs of C5/C6 and C6/C7 resulting in a favorable long-term outcome.
Clinical Significance Arthroscopic removal is a valid option for horses showing clinical signs that can be attributed to osteochondral fragments in the APJs of the neck.
