I too must have missed this.
What is LCP and FHO?
In any case,it's good news that she is recovering.
Legg-Calve-Perthes Disease (LCP) is a disorder of hip joint conformation occurring in both humans and dogs. In dogs, it is most often seen in the miniature and toy breeds between the ages of 4 months to a year.
LCP results when the blood supply to the femoral head is interrupted resulting in avascular necrosis, or the death of the bone cells. Followed by a period of revascularization, the femoral head is subject to remodeling and/or collapse creating an irregular fit in the acetabulum, or socket. This process of bone cells dying and fracturing followed by new bone growth and remodeling of the femoral head and neck, can lead to stiffness and pain.
LCP is believed to be an inherited disease, although the mode of inheritance is not known. Because there is a genetic component, it is recommended that dogs affected with LCP not be used in breeding programs.
The degree of clinical severity of LCP varies, and treatment can vary accordingly.
In mild cases, the dog may occasionally resist bearing weight on the affected leg or may exhibit periodic lameness. In these cases, limited activity and treatment with non-steroidal anti-inflammatory drugs (NSAIDs) may be sufficient.
In more severe cases as the pain and discomfort experienced increase, the dog may become totally lame and avoid all use of the affected leg. Furthermore, the leg muscles may begin to atrophy after extended periods of non-use. In severe cases, treatment often resorts to excision of the femoral head and neck. By removing the femoral head and neck, the bone on bone contact that is the source of the pain and discomfort is eliminated. Later, through the healing process and with therapy, a new false joint is formed by muscle and tissue, and the dog may have a complete recovery.
I hope this helps explain it, Zoey had a severe case so she had to have the FHO surgery that is explained here, she had gained one point towards her championship before she started exhibiting signs, so she was spayed while in surgery as well.
