Plan of action 

1. Further orthopedic evaluation under anesthesia
2. Radiographs of both hips under anesthesia
3. CBC

Further evaluations if needed include joint tap and culture, SLE testing, 
testing for RF to rule out septic or immune-mediated arthritis.

Hypothesis 1
If problem is due to hip laxity one would also expect to see ortalani sign in 
painful hip and see malformed hips (shallow acetabuli, femoral heads not 
enclosed completely within acetabuli- subluxation, and bone remodeling-
osteophytes) on radiographs. 

Hypothesis 2
Would expect to see radiographically what abnormalities exist.  Could be joint 
mice, cartilage erosion, joint remodeling, hip subluxation.  

Hypothesis 3
In infection or inflammation would expect to see leukocytosis in CBC. Possibly 
see increased opacity and soft tissue swelling around hip.  Bones would appear 
normal.
