SLOB

The normal hip is built for optimum movement using optimum control. It has no defense against sustained angular backward thrusting caused by dystonic reflex patterns. “Windswept” posture (both legs leaning together toward one side) will have the adducted hip (this case = left) socket damaged more than the opposite side which is centered by the dystonia. Normal structure cannot withstand these piston adducted forces. Back to normal? Normal was and still is NOT strong enough! If you see windswept, or sustained scissoring posture, then you have all the early detection that you need to act to prevent hip damage that follows. Not acting is a destructive process. 'Early detection' is posture observation. A 'normal' x-ray does not = a normal hip as x rays are blind to the cartilage damage.

In this illustration of adduction backward pressure (red arrows) damaging the shallow socket, notice the upper right inset of a hip ball-in-socket in white vs. a striking bag (boxer's speed bag) ball in socket (light blue). The latter is the goal of SLOB

reinforcement. Turn a yarmulke into a football helmet. As the hip grows it must grow WITHIN this enclosure and so even later cases deepen with growth.
