Use of a bioabsorbable implant for the repair of severed digital flexor tendons in four horses.

The study details the use of a new bioabsorbable implant made from poly-L-lactic acid in repairing broken digital flexor tendons in four horses. The research, which involved immobilizing the limbs of the horses and monitoring their recovery over several months, suggested the implants were well assimilated and effective, though results varied among the subjects.

Overview of the Study and Methodology

• The article describes a research study aimed at assessing the effectiveness of a new implant made from poly-L-lactic acid material, which is naturally absorbable, for the repair of damaged digital flexor tendons in four horses.
• The affected limbs of the four horses were immobilized using casts that were changed after a period of six to eight weeks and completely removed after 12 to 16 weeks.

Observation and Findings

• The horses’ healing was monitored over a period of seven to 19 months after the surgery, using both clinical and ultrasonographic examinations.
• Ultrasonographic examination after the removal of the cast showed that the implants were well assimilated into scar tissue, indicating successful integration with the horses’ biological tissue.
• It was observed that the recovery of the horses varied, with two out of the four horses returning to normal activities a year after surgery, while the remaining two were still hindered by lameness.

Results and Implications

• The procedure did not present any complications associated with the implant, suggesting it was well tolerated by the subjects.
• The study demonstrates the potential use of the bioabsorbable implant for tendon repair in horses, opening new avenues for treating such injuries in veterinary medicine.
