San Diego medical device company NuVasive reported $281.6 million in second quarter earnings, an 8.5 percent year-over-year jump.

The figure exceeded forecasts; analysts expected $276.1 million, according to a survey from Zacks Investment Research.

NuVasive stated that net income was $11.5 million, or 22 cents per share, compared to 21 cents per share in the second quarter in 2017. Adjusted to exclude one-time items, earnings per share were 58 cents, in line with Wall Street expectations.

NuVasive said growth was driven by the spinal hardware business, where case volumes were up 7 percent versus the prior year.
