The Food and Drug Administration has approved Alphatec Holdings' (NASDAQ:ATEC) Solus device. That means that the firm now has clearance to market and sell the product in the US.

Solus, described by the company as an internal fixation anterior lumbar interbody fusion device, is a ring that helps space the vertebrae apart and stabilize the spinal column.

This is not Alphatec's first market for the product. It was launched in Europe this past January, and the firm says that sales there have been successful.

In the press release announcing the FDA's approval, the company quoted a Millennium Research Group estimate that pegged potential 2013 sales of internal fixation ALIF products such as Solus at $129 million.
