Diagnosis
Conditions or ailments that are the cause of a problem that you see - your observation.
Your vet may diagnose
Foal or Newborn, Angular Limb Deformity, ALD
Synonyms: Valgus & Varus Deformities Generally
Summary
An angular limb deformity (crooked or angled limb) is noticed when looking at an equine limb from the front or back. (Abnormalities noted when viewing equine limbs from the side are called flexural deformities.)
Angular limb can result from problems within the joint, underdeveloped small joints of the hock and carpus (seen frequently in premature or dysmature foals), or be caused by uneven growth across the growth plate (physis). Radiographs are used to help differentiate between these conditions.
In young foals, there is a short window of opportunity in which to treat angular limb deformities. Problems affecting the growth plates can be treated before they have closed. Due to this, it is important to immediately contact your vet when you first notice the problem.

Diagnostics Used
These are tests that might be helpful to make this diagnosis or further characterize the condition.
Treatments May Include
These treatments might be used to help resolve or improve this condition.
PROGNOSIS AND RELEVANT FACTORS
Depends on the specific bones involved, and the severity of the abnormality. Depends on how soon the problem is appropriately treated. Once the growth plates have "closed" there is very little opportunity to help the situation.my role
I might observe
You might make these observations when a horse has this condition.
Questions To Ask Your Vet:
- Why did this happen, is it genetic?
- If I breed this horse will this problem be passed onto their progeny?
- Is this related to underdevelopment of the small joint bones or at the growth plate?
- What nutritional & management changes should I make as part of treatment?
- How much improvement can I expect with the different options?
- What is my role in follow-up care after treatment?
Prevention
Breed and select for correct conformation. Carefully evaluate the limbs of newborn and growing foals and communicate with your vet immediately if you have any questions or concerns.
