MORE THAN THREE-QUARTERS OF A MILLION PEOPLE WILL HAVE A HIP REPLACED THIS YEAR.
BUT SOME MAY BE A LITTLE GUN SHY AFTER A LARGE F-D-A RECALL OF METAL-ON-METAL DEVICES.
THEY CAUSED INFLAMMATION, TISSUE DEATH, HEART AND NERVOUS SYSTEM PROBLEMS.
NOW, A NEW IMPLANT IS REPLACING THE METAL WITH SOMETHING SAFER.
DOCTOR STEVEN HARWIN HAS BEEN DOING THIS FOR 30 YEARS.
REPLACING 15 HIPS A WEEK. GILBERT RAMIREZ TALKED TO US A FEW MINUTES BEFORE HE WAS GOING TO MEET UP WITH DOCTOR HARWIN IN THE O-R. AS A NEW YORK CITY TOUR GUIDE- HE RIDES ONE OF THESE ALL DAY LONG.
"You figure there are 20 stops, you're constantly going up and down the stairs. That's when I noticed my hip started to give me a lot of pressure."
HIS RIGHT HIP- WEARING BONE ON BONE.
"It stops you dead in your tracks."
GILBERT IS GETTING A NEW TYPE OF HIP REPLACEMENT CALLED MODULAR DUAL MOBILITY HIP OR M-D-M.
"This is what a contemporary hip replacement looks like."
A METAL SHELL, A PLASTIC INSERT AND THE IMPLANT ATTACHES IT TO THE THIGH BONE.
"The plastic can wear out."
THE NEW M-D-M REPLACEMENT USES A PORUS TITANIUM SOCKET THAT ALLOWS BONE TO GROW INTO IT.
"The range of motion is quite large, and the bearings move in conjunction with each other."
TONY RENTERIA HAD THE M-D-M REPLACEMENT A MONTH AGO. GETTING AROUND ON FOOT IN THIS CITY WAS A MUST, BUT...
"I could not walk at all."
NOW, 30 DAYS AFTER SURGERY-HE'S WALKING WITHOUT A CANE. "From the next day, I felt absolutely fine. It was like I had no pain whatsoever!"
TONY'S PATH TO RECOVERY CONTINUES.
AND HE'S PRACTICALLY PAIN FREE-EACH STEP OF THE WAY.
WHILE IT'S RELATIVELY NEW IN THE U-S, THE M-D-M HAS BEEN USED IN EUROPE FOR DECADES.
DOCTOR HARWIN IS ONE OF 30 SURGEONS WORLDWIDE WHO HELPED IMPROVE THE DESIGN AND UPDATE IT WITH MORE MODERN, LONGER LASTING MATERIALS.
HE SAYS ABOUT 90-PERCENT OF TRADITIONAL HIP REPLACEMENTS LAST 15 YEARS OR LONGER.
HE HOPES THE M-D-M WILL GIVE PATIENTS EVEN BETTER OUTCOMES BY HELPING REDUCE DISLOCATION OF THE IMPLANT.
