Case study: Scoliosis in a Bonobo (Pan paniscus).

Differential diagnosis of observed morphological features on an adult male bonobo skeleton was consistent with idiopathic scoliosis. Directional asymmetry was an order of magnitude higher compared with asymptomatic skeletons. This possible case of idiopathic scoliosis contributes to data that suggest a weaker tie between bipedalism and scoliosis than previously hypothesized.
