I have just done my second direct superior hip replacement (the first was 3y ago) and can hardly recommend it strongly enough, at least in the hands of DWard at NEBH Boston. Zero precautions and straightforward, fairly quick recovery, with the usual major ('why did I do this?') discomforts for the first couple weeks. Can't wait to get back to geezerball like the last round.
(Anent nomenclature, Ward called his approach, 3y ago, direct superior slight supercap; he trained w SMurphy, the Superpath guy, and I got Ward's name from Murphy's office, which was scheduling over a year out. I did not know either doc, just wanted to be able to return to bball. Have not yet gotten his op note for this latest TH.)
I've had one hip done Direct Superior and am about to have the 2nd done. Dr. Kelly here in W. Mass--he did a fellowship at NEBH. Easy recovery, no pain meds other than acetaminophen, only precautions are common sense--if it hurts or feels funny don't do it.
