What is pathological and what is adaptive?

Two studies in the 4-11 edition of the AJSM provoke this question:

"High Prevalence of Pelvic and Hip Magnetic Resonance Imaging Findings in Asymptomatic Collegiate and Professional Hockey Players"- Silvis et al.

"Magnetic Resonance Imaging of the Throwing Elbow in the Uninjured, High School–Aged Baseball Pitcher"-Hurd et al.

In a previous post I spoke of this issue regarding the finding of osteophytes in athletic knees.  Some researchers felt this was a pathological change, others felt is was a strategic reinforcement that the body does.  The same was discovered in the elbows of healthy high school pitchers and the hips of healthy collegiate and professional hockey players. What was really interesting was the presence of  asymptomatic adductor–abdominal rectus enthesopathy in hockey players.  The body self organizing?
