Arthroscopy is an alternative to CT scan for diagnosing humeral intercondylar fissure (incomplete ossification of the humeral condyle), typically seen in Spaniels. This is a line of weakness in the lower end of the humeral condyle that can propagate into a fracture (see separate articles on condylar fracture and Y fracture, in the case study section on fractures).
Arthroscopy allows probing and examination with the benefit of excellent magnification. If HIF/IOHC is confirmed, then we place a bone screw across the condyle of the humerus to support this area and reduce the probability of fracture.
