Incomplete ossification of the humeral condyle(IOHC)
Also known as: Incomplete humeral condylar ossification · Humeral condylar fissure · HCF · Inkomplette Ossifikation des Humeruskondylus · HIF · …
Overview
What it is
This skeletal condition, also known as humeral intracondylar fissure (HIF), occurs when the two halves of the lower upper-arm bone (the humerus) in the elbow joint do not fuse together properly into a single solid bone. This failure to fuse, which can be developmental or acquired over time, leaves a permanent weakness or crack in the elbow joint. Because of this structural weakness, the bone is highly vulnerable to painful fractures even during normal, everyday activities.
How it presents
Owners typically notice limping or stiffness in one or both front legs that comes and goes, or a sudden, severe lameness if the weakened bone fractures. These symptoms can appear at any time from a few months of age to several years, and are particularly common in spaniel breeds.
Treatment
The condition is treatable and usually requires a one-time surgical procedure to insert a specialized screw that stabilizes the elbow joint. This surgery typically costs between 1,500 and 5,000 EUR and offers a good long-term outlook if performed before a major fracture occurs.
