Bilateral tibial metaphyseal stress fractures associated with physitis in a foal.

The research paper explores a case of a 7-month-old foal experiencing significant lameness in its hind legs, necessitated by bilateral tibial metaphyseal stress fractures that came with a physitis condition. Corrective measures were taken, which included rest and dietary adjustment; however, the issue cropped up again when the foal was 14 months old.

Case Study Background

• The subject of the study was a 7-month-old Appaloosa foal, which was diagnosed with a lameness condition. It was found to be struggling to rise from laying down without aid.
• This condition was aggravated by the flexion of the tarsal – a group of bones in the hind limbs of most land-dwelling vertebrates.
• The foal exhibited a pronounced swelling in the distomedial part of the tibias, which was associated with significant pain when touched or put under pressure.

Diagnosis and Treatment

• The foal was subject to radiography, which revealed an unusual enlargement of the distal tibial metaphysis physis, differing from what is normally observed.
• Radiolucent fissure lines, observed as proximally extending from the physis into the medial aspect of the metaphysis, were indicative of stress fractures.
• Initial treatment involved rest and dietary adjustments, aimed at aiding the recovery of the foal and adjusting for its nutritional needs according to the condition.

Reoccurrence and Further Treatment

• Despite the initial treatment appearing to alleviate the condition, the leg problems re-emerged seven months later — when the foal was 14 months old.
• Subsequent treatment included a long-term break consisting of a 7-month pasture rest without any forced exercise.
• Following this extended rest period, it was reported that the foal had successfully recovered and was displaying regular health and behavior.
