The author has reported a comparative prospective randomized study of the technique for release of the iliopsoas tendon at the lesser trochanter and transcapsular at the hip periphery, and found ...

The side receiving the osteotomy was randomly assigned. Femoral necks were cut 15 mm proximal to the top of the lesser trochanter.

The Sydney AFF score was then developed based on the following 3 dichotomized independent predictors: age, femoral neck width, and lateral cortical width at the lesser trochanter.

This research makes it clear that the lesser trochanter is more important than previously identified. They conclude that understanding the real anatomy is key.
