text: Yo, check it out, here's the lowdown
  We had 69 young rabbits, just five days old
  Their right hips were dislocated, surgical intervention
  To study changes in the joint, that's our intention
  
  Left hips were the control, untouched and fine
  But the dislocated ones, that's where we draw the line
  We observed 15 survivors, killed 'em after two months
  To examine 'em closely, like some scientific hunts
  
  Macroscopic and microscopic, we went deep
  At two months old, fibrous degeneration, it did creep
  About 50% of those dislocated hips, they were affected
  The articular cartilage, it showed signs of being wrecked
  
  And when four months passed, we did the same
  14 rabbits studied, it's all part of the game
  The acetabulum, the dislocated hips took a hit
  Fibrous degeneration, all cases, every bit
  
  But the femoral heads, they seemed to stay fine
  Normal cartilage, no fibrous degeneration in line
  Only 25% of four-month-old rabbits showed the change
  The rest were resilient, kept their structure arranged
