DOCTOR, IF YOU NEED A HIP REPLACEMENT, YOU MIGHT BE A GOOD CANDIDATE FOR WHAT’S CALLED A DUAL MOBILITY IMPLANT. MERCY MEDICAL CENTER. DOCTOR MARK HUNGERFORD SAYS THE IMPLANT IS DESIGNED TO HELP STABILIZE THE HIP AND PROVIDE ADDITIONAL MOBILITY. AND DOCTOR HUNGERFORD JOINS US NOW WITH MORE INFORMATION. GOOD MORNING. HOW ARE YOU? I’M DOING WELL. SO WE’VE SEEN THE IMPLANTS AND ALL OF THESE THINGS COME SO FAR. THE TECHNOLOGY IN THEM TO REALLY LIKE MIMIC REAL MOVEMENT. SO TELL US ABOUT THIS DUAL SITUATION THAT WE HAVE HERE. RIGHT. SO FIRST, TO UNDERSTAND IT, THIS IS WHAT A TRADITIONAL IMPLANT LOOKS LIKE. IT HAS A SOCKET COMPONENT. YOU HOLD IT UP A LITTLE BIT MORE. THERE YOU GO. IT HAS A SOCKET COMPONENT THAT’S MADE OUT OF TITANIUM AND HAS A POROUS BACKING. AND THEN IT HAS A LINER. THIS IS POLYETHYLENE OR A PLASTIC THAT SNAPS INTO THAT SOCKET. OKAY. THAT’S HOW THE TRADITIONAL ONE WORKS. AND THEN YOU HAVE A STEM AND THE STEM HAS A BALL ON IT. AND THAT’S WHAT MAKES THE BALL AND SOCKET JOINT. OKAY. NOW IT IS POSSIBLE FOR THESE TO POP OUT OF THE SOCKET AND THAT’S CALLED A DISLOCATION. IF THE HIP DISLOCATE, IT’S A BIG PROBLEM. YOU HAVE TO GO AND PUT IT BACK IN. CERTAIN PATIENTS ARE MORE PRONE TO DISLOCATION AND THEREFORE THIS NEW TECHNOLOGY WAS INVENTED THAT ALSO HAS A SOCKET COMPONENT. BUT THE BALL HAS THIS ADDITIONAL POLYETHYLENE CAP ON IT. AND SO WHEN YOU PUT IT ON THE STEM, YOU NOW HAVE A BIGGER BALL AND YOU HAVE TWO PARTS THAT ARE MOVING, WHICH MAKES IT MORE RESISTANT TO DISLOCATION. THAT’S THE ESSENCE OF IT. NICE. I MEAN, THE WAY YOU’RE TALKING ABOUT IT, YOU CAN REALLY TELL. I MEAN, WITH THE VISUALS OF COURSE, YOU CAN REALLY TELL HOW THE MOVEMENT IS GREATER. YEAH. AND THESE ARE VERY HEAVY. AND I GUESS WHEN YOU LET ME HOLD IT, IT HAS TO BE BECAUSE IT’S MIMICKING A VERY IMPORTANT JOINT AND BONE IN YOUR BODY. RIGHT? SO THE, THIS, THIS HIP IMPLANT IS PLACED INSIDE THE FEMUR AND YOUR WHOLE BODY WEIGHT IS ON IT. SO IT’S MADE OUT OF TITANIUM AND IT’S BEEN TESTED TO BE VERY STRONG, TO NOT BREAK OVER THE LIFE OF THE IMPLANT, WHICH MAY BE 20, 30, 40 YEARS. AND WHO DID YOU SAY WAS A GOOD CANDIDATE FOR SOMETHING LIKE THIS? SO THE ONE CONCERN THAT WE HAVE WITH THIS TECHNOLOGY IS WE’RE ADDING AN ADDITIONAL PART. SO IS THERE A RISK OF, YOU KNOW, AN UNINTENDED CONSEQUENCE WHERE WE MIGHT HAVE A FAILURE OF THIS ORIGINAL PART? SO WE DON’T USE THEM FOR EVERYONE? WE USE THEM FOR PEOPLE WHO HAVE A HIGHER RISK OF DISLOCATION. AND THAT MIGHT BE SOMEBODY WHO’S HAD A HISTORY OF BACK SURGERY, SOMEBODY WHO’S HYPER FLEXIBLE, SOMEBODY WHO HAS A EHLERS-DANLOS, SOMEBODY WHO HAS HIP DYSPLASIA. SO THERE ARE A VARIETY OF PATIENTS FOR WHOM THIS IS A GOOD IDEA. ALSO, REVISION SURGERIES, IF YOU HAVE TO HAVE YOUR HIP REDONE FOR WHATEVER REASON, THOSE ARE AT HIGHER RISK OF DISLOCATION. AND THEN THIS TECHNOLOGY MIGHT COME INTO PLAY TO HELP STABILIZE THE HIP. I REALLY LOVE HOW YOU GUYS HAVE GOTTEN SO CREATIVE WITH JUST REALLY HELPING PEOPLE WITH THEIR RANGE OF MOTION. AND LIKE YOU SAID, THIS MAY NOT BE FOR EVERYBODY, BUT FOR SOMEONE WHO IT IS GOOD FOR, IT REALLY CAN GIVE YOU THAT RANGE. AND I KNOW THAT YOU GUYS GET PEOPLE UP AND MOVING RIGHT AFTER HIP SURGERY, SO YOU’RE NOT REALLY DOWN. YOU DON’T WANT THAT. YOU WANT THEM UP AND MOVING. WELL, THAT’S ABSOLUTELY TRUE. SO WE WE TRY TO GET PEOPLE OUT OF BED. THE SAME DAY. AND THE GOAL OF OF HIP REPLACEMENT SURGERY HAS ALWAYS BEEN TO RESTORE FUNCTION AND RESTORE RANGE OF MOTION. AND SO WE’RE ALWAYS LOOKING AT NEW TECH ANALOGIES THAT HELP US DO THAT IN A BETTER WAY FOR OUR PATIENTS. NOW. NOW, IS THERE ANYBODY ELSE WHO SHOULD LOOK INTO SOMETHING LIKE THIS IF THEY HAVE NO. THAT THEY HAVE MAYBE A HIP SURGERY THAT THEY NEED? IF THEY’VE BEEN TOLD THEY NEED A REPLACEMENT? RIGHT. SO WITH ALL TECHNOLOGY, THERE’S A LOT OF INS AND OUTS OF INDIVIDUAL THINGS AND WHO IT’S GOOD FOR AND WHO IT’S NOT. MY BEST ADVICE IS CONSULT YOUR SURGEON. I THINK MOST PEOPLE WHO DO HIP REPLACEMENTS ARE AWARE OF THIS TECHNOLOGY AND EMPLOY IT IN SOME FASHION AND AND I THINK FOR ME AND THIS IS MY PERSONAL PREFERENCE, IT’S KIND OF A MISTAKE TO GO IN AND TELL YOUR DOCTOR, YOU KNOW, HOW YOU WANT THINGS DONE, FIND A DOCTOR THAT YOU THINK IS GOOD, ASK HIM WHAT HE THINKS, WHAT HE OR SHE THINKS IS BEST FOR YOU AND YOU KNOW, AND GO WITH THAT. YEAH, IT’S GREAT TO HAVE YOUR IDEAS, BUT THEY HAVE THE EXPERTISE, SO IT’S MORE LIKE TEAMWORK MAKES THE DREAM WORK. EXACTLY. YEAH, EXACTLY LIKE THAT. YEAH. THANK YOU SO MUCH FOR JOINING US THIS MORNING. THANK YOU FOR HAVING ME. ABSOLUTELY. AND IF YOU HAVE ANY OTHER QUESTIONS OR WOULD LIKE A
