Local media reported that the older teen was seen in a neck brace when he was lifted into an ambulance, bound for intensive care.
He remained in serious condition as of Wednesday morning, according to the Hospital Authority.
According to the park’s website, it has a jumping area of more than 7,000 sq ft with over 40 trampolines and facilities such as an obstacle course, a trapeze, foam pits and bounce boards.
Participants must sign a waiver before entering the venue “even if they are not jumping”, and a parent or legal guardian must provide a signature on behalf of those aged under 18.
The waiver states customers will give up rights to sue the company “for any injury, including paralysis or death” caused by play at the park.
The playground’s general rules stipulate participants should keep “an appropriate amount of space” between themselves and others to avoid collisions.

“Trampoline or attraction use involves an inherent risk. Impact can result in serious or fatal injury, paralysis and fracture. Participate at your own risk,” the park warned in its guidelines.
Other rules include a minimum age of seven years to use its “euro trampoline”, with only one person allowed at a time.
A safety video on its website also showed that there should be only one participant per designated square on its shared trampoline and visitors should “be aware” of those around them.
Local media in 2016 reported that United Christian Hospital recorded at least 16 people who were injured from July 2015 to January that year after playing at a trampoline park in Kowloon Bay.
In 2018, it was reported that Kwong Wah Hospital treated three cases of serious bone fractures within two months with one man almost becoming paralysed, also from trampoline play.
Pamela Youde Nethersole Eastern Hospital stated in a case report published in the Hong Kong Medical Journal in 2018 that since the opening of the first trampoline park in Hong Kong in 2014, it had noticed an increase in related injuries that required admission to its orthopaedics department.
