What is the most likely diagnosis based on the information given? A mildly obese patient comes to your office complaining of buttock pain. She fell on her buttocks about one week ago and she still has some residual pain. Inspection of her lumbar spine and gluteal region reveals a decreased lumbar lordosis. Standing flexion test and seated flexion test show no evidence of asymmetry. Sacral sulci are equal in depth. The lumbosacral junction does not spring.

Bilateral sacral extension

The above patient has a bilateral sacral extension (a.ka. sacral base posterior or a posterior sacral base). The seated flexion test will be FALSELY negative-Why? Since both SI joints are restricted, asymmetry will bot be appreciated.
