55 years old lady came to us with complaints of pain in right hip with shortening of 5 cm. She had a hip replacement 40 years back which had failed. She was barely managing with a walking stick till now. She had severe pain for the last 6 months. We performed Total Hip Replacement. The acetabulum bone was inadequate which had to be supported with a special implant called Mueller’s Ring into which a poly cup was cemented. The shortening was also corrected and she now has a pain free stable hip.
