Ultrasound assisted arthroscopic approach for removal of basilar sesamoid fragments of the proximal sesamoid bones in horses.

The research study reports a successful procedure for removing basilar sesamoid fragments in thoroughbred yearling horses using ultrasound guided arthroscopy.

Objective of the Study

• The primary aim of the study was to assess the efficacy and safety of an ultrasound-assisted arthroscopic approach to remove non-articular basilar sesamoid fragments in Thoroughbred yearlings. These fragments were detected during pre-sale radiographic examination.

Methods

• The process of fragment removal involved a palmar/plantar arthroscopic approach to the fetlock joint, aided by ultrasonographic guidance.
• Tools used for the operation included rongeurs, which are a type of forceps used for removing bone and hard tissue, and a radiofrequency probe for soft tissue dissection of the fragment.
• The successful and complete removal of the fragments was confirmed by further ultrasonography and radiography.

Results

• The procedure resulted in the successful localization and removal of the basilar sesamoid fracture fragments.
• No intra- or postoperative complications occurred, suggesting that the procedure had minimal risks involved.
• At a follow up 6-8 months later, no leftover fragments or bone proliferation at the base of the sesamoid was observed, indicative of the procedure’s success and the absence of any recurring issues.

Conclusions

• The research concluded that ultrasonographic guidance could effectively facilitate the localization, dissection, and confirmation of removal of basilar fragments of the proximal sesamoid bone in horses, validating this as a safe and efficient veterinary procedure.
