An artificial hip developed by a Kyocera Corp. subsidiary is finding favor in surgeries for osteoarthritis and fractures and has been used in 10,000 cases in the two years since it hit the market in October 2011, company officials said.

Given that doctors perform about 50,000 hip surgeries per year in Japan, the surging popularity of the Aquala Liner by Osaka-based Kyocera Medical Corp. is exceptional, they said.

The device is popular with doctors who want to reduce the risk of repeat operations because it has a special coating on the interlocking section supporting the upper body that makes it last longer than conventional products, they said.
