Bill Hartman & Zac Cupples refer to this as a right oblique turn versus the other pattern they see which is a right flat turn. Others would lump this into a L AIC, but it doesn't fit that traditionally because the left iliac crest appears higher and the traditional PRI pattern has the right side being hiked.
Jerry's Reply: The Hesch Model does not rely on observation as ~30% have developmental symmetry in the pelvic bones, but rather is based on treatable mobility impairment, hence the Hesch-developed load-spring-recoil tests. Further to that, standing assessment is limited because it captures the compensation, whereas in gravity-reduced positions, the cause is clearly discerned.
