(WXYZ) — A new study from Michigan Medicine states that serious fireworks injuries doubled after a law in Michigan loosened restrictions on fireworks.

RELATED: After Fourth of July marred by tragedy, should Michigan change fireworks laws?

Ten years ago, the Legislature changed the law, allowing residents to launch their own displays into the air legally.

The study shows that after the new law went into effect, the number of patients getting care for fireworks-related injuries at University of Michigan hospitals doubled.

Researchers say almost all of the increase came from a jump in injuries caused by large airborne fireworks launched from tubes called mortars, the same type that killed Columbus Blue Jackets goalie Matiss Kivlenieks over the recent July 4 holiday weekend.

The study also shows a significant increase in a specific type of injury called traumatic amputation, which could involve fingers, hands, or limbs.

The study was led by Melissa Shauver, M.P.H., when she was a research coordinator at the University of Michigan, and Kevin Chung, M.D., M.S, a U-M professor of plastic surgery and hand surgeon at Michigan Medicine, U-M’s academic medical center.

It covers the years 2005 to 2018, and examines records from patients treated at Michigan Medicine for injuries related to non-professional fireworks use.

“Since the Michigan Firework Safety Act was first proposed it has been hotly contested. However, there was no evidence to provide context to this policy debate,” said Shauver, who is now at the Feinberg School of Medicine at Northwestern University. “We knew that Michigan Medicine, as both an adult and pediatric level 1 trauma center and the home of a specialized ophthalmology emergency department, could provide this data and contribute to the assessment of this law.”

You can find key findings from the study below:

From January 2005 to December 2011, 81 patients came to U-M for fireworks-related emergency care, including 33 injured by airborne fireworks that were illegal for individuals to buy or use in the state at the time.

The 2011 law, which went into effect in January 2012, was intended to counter the unregulated use of airborne fireworks purchased in states where they were legal, and to avoid the resulting tax revenue loss to the state.

From January 2012 to December 2018, the number of patients treated at Michigan Medicine for fireworks injuries rose to 160. Nearly half – 74 patients – were injured by mortars, up from 20 in the years before the law changed.

In both time periods, around 70% of the patients were transferred from other hospitals in Michigan, reflecting the seriousness of injury. Patients injured by fireworks in other states and transferred to Michigan Medicine were not included because of variation in state fireworks laws.

Even after the researchers took into account the increase in all types of emergency care at Michigan Medicine during the study period, the jump in fireworks-related injuries still held.

More than 80% of the patients arrived at U-M in June or July, with 62% coming within the two weeks surrounding July 4. Forty percent were under age 18.

The researchers also traced the long-term impacts of the fireworks injuries on the patients who received follow-up care from Michigan Medicine. While 71% of patients didn’t experience a long-term physical disability, six patients lost an eye, six others lost most of the sight in one or both eyes, six had fingers amputated, and one had a traumatic brain injury.

Chung said the trend of lasting hand injuries has continued in 2021.

“Firework injuries are common. This is a preventable injury that leads to long term consequences when the hand is blown up, which invariably ends with loss of fingers and sometimes the whole hand,” he said. “During this year’s July 4th holiday, I have had to care for patients whose lives are forever changed by firework injuries and who require a series of complex reconstruction just to preserve some semblance of hand function. The personal, economic and society consequence of this preventable injury is immeasurable.”
