Yeah... it's 2 a.m. and I'm still up studying the pelvis... Woah, listen **Verse 1** Rectus femoris, yeah, it starts at the AIIS, Anterior inferior iliac spine, know it, no guess. Labrum's a fibrocartilage ring, goes all the way around, Ring of Saturn on the acetabulum, tightest seal in town. I know you're tired, second year, I feel it too, But I'm not gonna let you fail, that's my word to you. **Hook** *(melodic, sung)* Ooh, hip, you're all I think about, Landmarks, breaks, and arthritis, yeah, I'm sure you'll figure it out. Ooh, and if you love me, take a cat home, My fosters need a family, don't leave them alone. **Verse 2** Femoral neck fractures, Garden one through four: Impacted, nondisplaced, partial, then displaced for sure. Pauwels going off the angle of the line, Steeper means more shear force, that's the design. Pipkin for the head, when the hip dislocates, Intertroch, subtroch, know the shaft, don't hesitate. **Hook** Ooh, hip, you're all I think about, Landmarks, breaks, and arthritis, yeah, I'm sure you'll figure it out. Ooh, and if you love me, take a cat home, My fosters need a family, don't leave them alone. **Verse 3** Now the film shows arthritis, here's what you gotta see: Joint space narrowing, that's the cartilage leaving me. Subchondral sclerosis, bone gets dense and bright, Subchondral cysts, little dark holes in the light. Osteophytes on the edges, spurs, they never lie, Four signs of OA, now you know why. **Outro** *(half-spoken)* Yeah... and look, I'm serious about the cats. They're sweet, they're litter-trained, they need a home. Adopt my foster cats. Anatomy's on the exam, cats are on me. Woah.
