History: 48-year-old female who goes to the gym 5 days a week experiencing right hip pain
Below: Dynamic clip of the latral hip during flexion/extention
The orientation is the same as in the previous image.
At left, we see bulging of the lateral capsule, which partially obstructs motion of the greater trochanter.
At right, the trochanter appears in the image during flexion.
Diagnosis: Early osteoarthritis with lateral hip impingement
