Lateral luxation of the superficial digital flexor tendon from the calcaneal tuber in two horses.

The research focuses on a surgical repair method for lateral luxation of the superficial digital flexor tendon from the calcaneal tuber in horses, a condition caused by a tear or rupture of the medial retinaculum of the tendon. The surgical procedure involved using two cancellous bone screws placed in the calcaneus lateral to the tendon, in conjunction with suturing the medial retinaculum.

Study Context

• Lateral luxation of the superficial digital flexor tendon from the calcaneal tuber is a condition that affects the locomotion in horses. This condition is commonly seen in thoroughbred race horses and can seriously hinder their performance capability.
• The condition is caused by a tear or rupture in the medial retinaculum of the tendon, which effectively displaces the tendon from its usual position against the calcaneal tuber.

Objective of the Study

• The researchers aimed to report on the surgical technique used to repair this condition in two thoroughbred race horses and assess its effectiveness.
• The surgical intervention involved the insertion of two cancellous bone screws into the calcaneus laterally to the tendon.
• The medial retinaculum, a tough band of tissue essential for holding the tendon in place, was also sutured during the procedure as it is often torn or ruptured in this condition.

Methods and Procedure

• Two thoroughbred racehorses identified with the condition were selected for the study.
• The surgical procedure to repair the condition was carried out on both horses. Two cancellous bone screws were inserted in the horse’s calcaneus lateral to the tendon.
• In addition to this, the torn or ruptured medial retinaculum, which caused the condition, was also sutured to provide stability and support to the tendon.

Significance of the Research

• This research holds significant value in providing a practical surgical solution for treating lateral luxation of the superficial digital flexor tendon from the calcaneal tuber in horses.
• The detailed account of the surgical procedure used in treating this condition helps in adding to the veterinary surgical corpus and could guide veterinarians in the treatment of similar cases.
• Through this report, veterinarians dealing with thoroughbred racehorses could be better equipped to handle this condition, enhancing the welfare, health, and athletic performance of the horses.
