| | | |
− | *Mainly large and giant dog breeds, especially with stocky conformations
| |
− | *Seen in cattle - Herefords
| |
− | *Subluxation of hip joint due to maldevelopment
| |
− | *Not present at bith
| |
− | *Inherited + environmental factor involvement (nutrition, exercise)
| |
− | *Pelvic muscles are behind the bone development in rapidly growing dogs -> lack of restraint of the joint -> excess movement before acetabulum is fully mature
| |
− | *Usually develops within first 6 months of life
| |
− | *Varying degrees of severity
| |
− | *Pathogenesis:
| |
− | **Joint laxity / acetabular dysplasia
| |
− | **-> Flattened femoral head +/- mild or severe periarticular [[Musculoskeletal Terminology - Pathology|osteophyte]] formation
| |
− | **-> Thickening of femoral head + degeneration of [[Joints - Anatomy & Physiology#Articular cartilage|articular cartilage]]
| |
− | **[[Musculoskeletal Terminology - Pathology|Eburnation]]
| |
− | *Predisposes to [[Joints Degenerative - Pathology#Degenerative joint disease (DJD)|DJD]]
| |
− | *Round ligament of femoral head may rupture -> luxation
