1. clamp it.

2. yes...more than I'd like...the anatomy is fibrous/dense/stiff and varied
depending on what's been done before.

3. I've never used a Judet table...only seen pictures and they look fancy, but we're not so fancy... and to my knowledge, I haven't needed one yet... but maybe I have and just didn't realize it. We just isolate the perineum, prep the lumbodorsal areas, flanks, and injured lower extremity in its entirety.
You'll need an assistant on the opposite side to retract, and another one on the injured side with you is ideal to provide suction and ipsilateral knee flexion... the ipsilateral assistant can also apply gentle distal-lateral hip traction using a trochanteric ridge bone hook or proximal femoral pin to disengage the head from socket in order to remove debris... your ability to view the joint is determined by the wall size and caudal transverse
segment's instability... the bigger the wall fragment retracted away and the more unstable the caudal transverse segment then the better the joint visualization...you can also use a universal distractor or external fixateur to distract the joint but it never fatigues (which is bad for a tensioned nerve), it must be applied in an appropriate vector, it may interfere with your visualization and obstruct your working into the joint zone, and it leaves holes in the supra-acetabular zone where you might like to apply implants later...so be smart when applying it. You don't need strong assistants, you need smart ones.
Thank you-
Chip
