Arboreal Pelvis. Leitz Summicron 50mm DR

While I was having Mama-In Law's car washed and detailed this morning, I noticed these conjoined trees.  As interesting as their fusion is in its own right, the shapes made me think of the x-ray of a pelvis, pelvic girdle at the top, hip joints and other parts in the middle, and femurs at the bottom.  What would the orthopedic guys think about all the skeletal irregularities?
