Spinal orthopedic device maker LDR Holding raised $75 million in an initial public offering. It is the first medical device company IPO in 2013 on a U.S. exchange, compared to 32 therapeutics developers that have gone public so far this year.

LDR sold 5 million shares at $15 a share, hitting the midpoint of its target range. The company plans to list its shares on the Nasdaq under the symbol LDRH. The company filed it offering confidentially under the JOBS Act in June.

LDR is a global company with a variety of marketed products used by surgeons to repair spinal disorders. It was founded in France in 2000 as LDR Medical, established a U.S. distributor, LDR Spine in 2004, and later moved its headquarters to Austin, Texas and incorporated under LDR Holding. The company’s sole focus is on the development of innovative technology for spinal procedures.

LDR received U.S. regulatory approval in August to market its Mobi-C Cervical Disc to treat more than one level of the cervical spine, the first such approval for a cervical disc in the United States. In clinical trials it has shown superiority compared to the standard of care treatment for cervical degenerative disc disease, which is anterior cervical discectomy and fusion—a surgical procedure to treat spinal cord compression.

LDR shares began trading at $18.70 and rose as high as $19.40, almost 30 percent, in early trading.
