Well I agree! But most ortho surgeons recommend early weight-bearing (as early as PO1). I've handled a lot of post-DHS pxs and I consider other factors to proceed with ambulation training with an assistive device (crutches or walker) such as the general condition of the px (hemoglobin level, orthostatic hypotension, strength of the univolved lower extremity and upper extremities and pain tolerance, etc.)

Sometimes even if the px's condition permits ambulation and you have the go signal from the ortho surgeon, it would be his fear that would prevent from proceeding. You have to convince him that it's alright or make ways to alleviate his fear. It's a case to case basis.

If you have some clarifications , you can email me. I hope i've contributed something. GOOD LUCK!
