Imagine a Saturday afternoon in the City of Wichita Falls. Maybe you were heading down Kemp Boulevard toward the Sikes Senter area, or perhaps your family was preparing for a birthday party at the local Urban Air Adventure Park. You watched your child run toward the trampoline courts, wristband secured, full of the kind of energy only a kid in the City of Wichita Falls can have on a weekend. Then, in less than two seconds, everything changed.

There was a collision, or a bad landing in a foam pit, or a “double-bounce” from a larger jumper that launched your child with forces their developing skeleton was never meant to handle. You heard what Kati Hill, a mother whose story went viral after her son broke his femur at a similar park, called “the worst scream that you could ever have heard from a child.”

As a senior attorney with over 25 years of experience at Attorney911, I have seen this scene play out for families across our state. Since 1998, Ralph Manginello has fought corporate defendants who put profit margins ahead of child safety. We have stood in the trauma bays of facilities like United Regional or watched the Life Flight helicopters prepare for transport to pediatric Level 1 centers like Cook Children’s in Fort Worth, knowing that what happened wasn’t a “freak accident.” It was the predictable output of a business model that ignores 25 years of medical warnings.

If your child was injured in a trampoline accident in the City of Wichita Falls, you are likely facing mounting medical bills, the panic of a permanent diagnosis, and a trampoline park manager pointing to a kiosk waiver you signed in a rush. You don’t need a general practitioner. You need a firm that has spent two decades taking on Fortune 500 giants like BP, Walmart, and Amazon. You need a team that includes a former insurance defense attorney, Lupe Peña, who used to write the very waivers these parks use to try to silence families.

We know the industry. We know the physics. And we know that in the City of Wichita Falls, your child’s rights are not as limited as the park wants you to believe.

The Reality of Trampoline Injuries in the City of Wichita Falls

Whether the injury happened at a commercial facility like the Urban Air on Kemp Boulevard or on a backyard Skywalker or Jumpking trampoline in a neighborhood near Lake Wichita, the medical reality is staggering. Nationally, more than 300,000 trampoline-related emergency room visits occur every year. In the City of Wichita Falls, we see these cases spike during the summer months when the North Texas heat drives families indoors to air-conditioned parks, and during the peak “birthday season” of January and February.

Recent medical literature has pulled back the curtain on just how dangerous these environments are. According to a landmark study by Teague et al. published in the journal Pediatrics in January 2024, foam pits are among the most hazardous attractions, with an injury rate of 1.91 per 1,000 jumper-hours. Even more alarming, the American Journal of Roentgenology noted in 2024 that up to 1.6% of all pediatric emergency department trauma visits are now trampoline-related.

This isn’t just about “kids being kids.” When a 200-pound adult lands on a trampoline mat just as a 50-pound child is pushing off, the energy transfer multiplies the child’s launch force by up to 400%. The child isn’t jumping anymore; they are a projectile. This “double-bounce” physics is the signature cause of the comminuted femoral shaft fractures and Salter-Harris growth plate injuries we litigate for families in the City of Wichita Falls.

Why the “Trampoline Park” Label is a Marketing Deception

The industry has evolved. What we call a “trampoline park” in the City of Wichita Falls is often a Family Entertainment Center (FEC) that has bolted on high-risk attractions like Sky Rider indoor coasters, 30-foot climbing walls, and ninja warrior courses. These attractions are often supervised by the same minimum-wage teenagers who receive as little as two to four hours of safety training.

Consider these verified industry patterns that affect families in the City of Wichita Falls:

  • The Urban Air Pattern: Branded indoor ziplines, like the Sky Rider, have been implicated in a chain-wide pattern of cord strangulations and falls in states like Georgia and Illinois.
  • The Altitude Fatality: In Gastonia, North Carolina, 12-year-old Matthew Lu died after falling 20 feet from a climbing wall because an employee failed to secure his harness. The park later admitted “human error” and removed the attraction.
  • The “Don’t Call 911” Protocol: A parent at a Texas Urban Air location reported on Tripadvisor that employees were supposedly instructed by management not to call 911 for injuries, downplaying broken bones to avoid public scrutiny.

We don’t accept the park’s version of events. While most firms handle these as simple slip-and-falls, we treat them as complex corporate accountability cases. We understand the 5-layer defendant stack: the local Operator LLC, the Franchisee, the Franchisor (like Sky Zone Franchising or UATP Management), the Corporate Parent (Sky Zone, Inc. or Unleashed Brands), and the Private Equity sponsors like Palladium Equity Partners or Seidler Equity. We go where the money is hidden because the City of Wichita Falls families we represent deserve a recovery that covers a lifetime of care, not just an ER bill.

The Paper Wall: Why Your Waiver Doesn’t End Your Case

The #1 reason parents in the City of Wichita Falls don’t call an attorney is the “kiosks waiver.” The park makes you believe that by tapping “I Agree” on an iPad, you have signed away your child’s future. That is a lie.

Under Texas law, there are several ways we dismantle these waivers:

  1. The Munoz Doctrine: In Texas, the landmark case Munoz v. II Jaz, Inc. established that a parent cannot bind a minor child to a pre-injury waiver of their personal tort claims. Your signature might affect your right to sue for medical bills, but it generally cannot stop your child from seeking justice for their own injuries.
  2. The Dresser Fair-Notice Standard: A waiver in the City of Wichita Falls must be “conspicuous.” If the legal release was buried in 20 screens of fine print without bold, contrasting text that uses the specific word “negligence,” it may be legally void under the Dresser Industries v. Page Petroleum doctrine.
  3. The Gross Negligence Exception: No waiver in Texas can release a company from gross negligence. This was proven in the Cosmic Jump $11.485 million verdict in Harris County. A 16-year-old fell through a hole in a trampoline mat onto a concrete floor. Because the park knew about the tear and didn’t fix it, the jury found gross negligence. The waiver was worthless.

Our team, lead by Ralph Manginello, knows how to spot these openings. Our associate attorney, Lupe Peña, spent years on the defense side, drafting and defending the same types of waivers Sky Zone and Urban Air use today. He knows where the holes are because he helped dig them. He also speaks Spanish natively—hablamos español—representing our bilingual families in the City of Wichita Falls directly.

Catastrophic Injuries: Moving Beyond “Broken Bones”

A trampoline injury to a child in the City of Wichita Falls is a biological event with a 70-year horizon. We don’t just see “broken legs.” We see:

  • Salter-Harris Fractures: Damage to the growth plate at age eight can lead to a limb that is measurably shorter or crooked by age fourteen.
  • Cervical Spine Trauma and SCIWORA: Spinal Cord Injury Without Radiographic Abnormality is a pediatric phenomenon where a child’s neck is injured even when a CT scan looks normal.
  • Vertebral Artery Dissection: As seen in the viral Elle Yona TikTok case (27M+ views), a backflip can cause a spinal-cord stroke, often misdiagnosed initially as a panic attack.
  • Rhabdomyolysis: This is a life-threatening muscle breakdown that releases myoglobin into the blood, leading to acute kidney failure.

Our firm is currently litigating a $10 million lawsuit against the University of Houston involving rhabdomyolysis. We use the same medical experts and the same institutional-accountability framework for trampoline cases in the City of Wichita Falls. If your child has dark, tea-colored urine or extreme muscle pain 24 hours after jumping, they need an ER immediately—and you need a lawyer who understands the nephrology of your case.

The Evidence Clock is Running in the City of Wichita Falls

If you wait to call an attorney, you are letting the park win. Trampoline park surveillance systems in the City of Wichita Falls typically overwrite footage on a 7-to-30-day cycle. The waiver kiosk database may purge version history every 72 hours. Incident reports get “revised” by corporate risk managers.

When you retain Attorney911, our preservation protocol begins within 24 hours:

  1. Certified Spoliation Letter: We demand the park freeze all DVR footage, training logs, and inspection records.
  2. Forensic Acquisition: We use tools like Magnet AXIOM and Cellebrite to recover digital evidence, just like in federal investigations.
  3. Expert Deployment: We immediately send a biomechanical engineer to study the energy transfer that caused the fracture and an ASTM compliance specialist to audit the park’s monitor-to-jumper ratios.

Call 1-888-ATTY-911 today. We handle trampoline injury cases in the City of Wichita Falls and nationwide on a contingency-fee basis. You pay nothing upfront, and we advance all costs for the surgeons, engineers, and life-care planners your child’s future depends on. If we don’t win, you don’t owe us a dime.

Frequently Asked Questions About Wichita Falls Trampoline Accidents

Can I sue if I signed the waiver at the Urban Air on Kemp Blvd?

Yes. As we discussed, Texas courts frequently void or limit these waivers, especially in cases involving minor children under Munoz v. II Jaz or when gross negligence is involved. The “paper shield” is mostly a deterrent to keep you from calling an attorney. Don’t let it work.

How long do I have to file a claim in the City of Wichita Falls?

Under the Texas statute of limitations (CPRC § 16.003), adults generally have two years from the date of injury. However, the time for a minor’s claim is “tolled” until they turn 18, meaning they have until their 20th birthday. But beware: while the law gives you time, the evidence does not. Video and witness memories will be gone long before the deadline.

Who is responsible if my child was double-bounced by another kid?

The park is responsible. ASTM F2970 requires parks to enforce age and weight separation. If the park allowed a 150-pound teenager to share a bed with your 60-pound child, they violated the industry standard and their own operations manual. They cannot outsource their duty to supervise to other children.

What is my child’s trampoline injury case worth?

Every case is unique, but we anchor our demands in national data. A Salter-Harris growth plate injury can range from $500,000 to over $2 million because of the lifetime of surgeries it may require. Catastrophic spinal cord cases can reach well into the eight-figure range, as seen in the $15.6 million Damion Collins award.

What if the park says they don’t have video of the accident?

We don’t take their word for it. We subpoena the hard drives, the NVR access logs, and depose the IT manager. If they destroyed video after our preservation letter, we seek an adverse inference instruction, where the jury is told to assume the video would have proven the park’s negligence.

Does it cost anything to start my case with Attorney911?

Zero. We work on a contingency fee. We are the ones taking the risk. We pay for the private investigators to go to the park, the medical specialists to review the imaging, and the economists to calculate your child’s lost future earnings. We only get paid if we recover money for you.

Why Attorney911 is the Right Choice for Your Family

Most personal injury firms in North Texas handle anything that walks through the door—car wrecks, barking dogs, slips. We are different. We built our firm to handle high-stakes corporate litigation.

When you call 1-888-ATTY-911, you are getting:

  • Federal Court Experience: Ralph Manginello is admitted to the Southern District of Texas and has 25+ years of trial experience.
  • The Defense Advantage: Lupe Peña knows the insurer’s playbook because he helped write it. He recognizes the “friendly adjuster” trap and the “Med-Pay Trojan Horse” check before you fall for them.
  • Medical Depth: Our active litigation on rhabdomyolysis cases means we don’t need a medical dictionary to talk to your child’s surgeon. We already have the expert network in place.
  • A Family Focus: As client Chad Harris said, “You are NOT a pest to them and you are NOT just some client… You are FAMILY to them.”

What happened to your child at the City of Wichita Falls trampoline park wasn’t an accident. It was the result of a chain of business decisions that favored throughput over safety. The American Academy of Pediatrics has been warning about this since 1999. The industry wrote ASTM F2970 to create a safety floor—and then they chose to jump right through it.

Your child’s case depends on what gets preserved this week. Don’t wait for the adjuster to call. Call 1-888-ATTY-911 now. Hablamos Español. The consultation is free, and the fight is ours.

The Architecture of Accountability: Every Party We Investigate

In a City of Wichita Falls trampoline case, we name everyone on the hook:

  1. Local Operator LLC: The entity that neglected the padding.
  2. Franchisor (Sky Zone Franchising/UATP Management): The entity that failed to audit the park for safety violations.
  3. Parent Company (Unleashed Brands/Sky Zone Inc): The private-equity-backed giant that cut staffing ratios to hit margin targets.
  4. Manufacturer (Jumpking/Skywalker/Springfree): If a weld failed or a net tore, the product manufacturer bears strict liability.
  5. Landlord/Sovereign entities: If the injury happened at a school or city-run facility, or if the building design contributed to the harm.

At Attorney911, we uncover every insurance layer—primary, umbrella, and excess. We have gone toe-to-toe with multinationals and made them pay. The conglomerates behind these parks don’t scare us; we have been beating their lawyers for 25 years.

A Detailed Look at Double-Bounce Physics for Wichita Falls Parents

When you’re standing at the rail at an Urban Air, the room is loud and the motion is chaotic. But for our biomechanical experts, it is a simple matter of kinetic energy transfer.

Imagine your child is on the up-cycle of a jump. Their body is accelerating upward. At that exact moment, a much heavier jumper lands on the adjacent section of the interconnected mat. This creates a “wave” of elastic energy through the polypropylene bed. When that wave meets your child’s feet, it doesn’t just add to their height—it snaps their lower leg before they even leave the mat.

Standard F2970 explicitly prohibits this “energy transfer” between jumpers of different weight classes. Most parks have a rule on the wall about “one jumper per square,” but on a busy Saturday, those squares are packed. When the park collects your money and hands over a wristband, they accept a non-delegable duty to enforce that rule. When they fail, and your child’s tibia suffers a spiral fracture from the torque, the park is liable for the results of the physics they chose to ignite.

Understanding the Salter-Harris Classification of Growth Plate Damage

For parents in the City of Wichita Falls, the word “fracture” is scary. But the words “Salter-Harris” are what keep us up at night. Because a child’s bones grow from cartilaginous plates, a fracture that crosses those plates (Types III, IV, and V) can cause the bone to stop growing entirely in that spot while the rest of the limb continues.

We work with pediatric orthopedic experts to build a Pediatric Life-Care Plan. We don’t just calculate your current hospital bill. we project:

  • Standardized MRI and X-ray monitoring every 6 months until age 18.
  • The high likelihood of corrective osteotomy (surgery to re-break and straighten the bone) in four years.
  • The cost of lifetime orthotics if one leg is permanently shorter.
  • The lost earning capacity of a child who can no longer pursue certain career paths due to physical impairment.

We don’t settle for a $50,000 offer that covers today’s cast. We demand a recovery that protects your child for the next seven decades.

High-Heat and Dehydration: The Hidden Rhabdo Risk in North Texas

Wichita Falls summers are brutal. While a trampoline park feels cool when you walk in, the “micro-climate” on a crowded jump floor can reach 85 degrees with high humidity from hundreds of breathing children. If a park has inadequate HVAC or doesn’t provide free, easily accessible water, they are courting Exertional Rhabdomyolysis.

If your child was allowed to jump for two or three hours straight on an “all-day pass” and now has severe pain and dark urine, do not wait. This is a medical emergency that can lead to permanent dialysis. Because our firm actively litigates a $10 million rhabdo case against a major university, we have the nephrology database already built. We have the experts who can look at the CK levels and prove that the park’s lack of hydration protocols was the direct cause of the kidney failure.

The Vanishing Evidence Protocol: Why 24 Hours Matters

The first thing a trampoline park risk manager does after an ambulance leaves the Kemp Blvd facility is check the DVR. They want to know what the cameras saw.

Our job is to make sure they don’t get the only copy.

  • The 7-Day Overwrite: Most digital video recorders (DVRs) in the family entertainment industry use “rolling” storage. Once the hard drive is full—typically in 7 to 14 days—the system automatically deletes the oldest footage to make room for the new.
  • The Certified Preservation Demand: By sending a spoliation of evidence letter within 24 hours of being hired, our firm puts the park on formal notice. If they “lose” the video after our letter arrives, we can move for Rule 37(e) sanctions in court.
  • Witness Canvass: The teenagers working the courts on Saturday will be gone in three months. High turnover is part of the business model. We find them while they still remember which manager told them not to call 911.

You have millions of dollars on the line. The park has a risk team already working to undermine you. You need a team that works as fast as they do.

Frequently Asked Questions – Continued

Is it a case if my child was hurt by another kid?

Yes. The park has a legal duty of “negligent undertaking.” Once they agree to monitor the courts, they must do so reasonably. If they allowed a “bully” or a much larger child to jump in a dangerous manner for ten minutes without intervention, the park’s failure to supervise is the proximate cause of your child’s injury.

The park offered me a free birthday party and a refund to sign a form. Is this a good deal?

Never sign that form. It is almost certainly a General Release of All Claims. For the price of a $300 party, they want you to walk away from a potential multi-million-dollar medical recovery. A legitimate refund for a service not provided never requires a legal release. If they ask you to sign, it’s because they know they’re in trouble.

What if we don’t have health insurance for our child?

We can help. We work with a network of medical providers who can treat your child on a “Letter of Protection” or lien basis. This means they get the surgery and physical therapy they need now, and the doctors wait for payment until the case resolves. Your child’s recovery shouldn’t be delayed by a deductible.

How do we prove the foam pit was too shallow?

We use the ASTM F2970 measurements. We subpoena the foam-rotation logs. If the park hasn’t refilled or fluffed the foam in six months, the cubes at the bottom are compacted into a hard surface. We retain a materials engineer to measure the density and depth. A “full” looking pit that is actually compacted below 3.5 feet is a death trap.

My child is scared of trampolines now. Can we recover for PTSD?

Yes. Pediatric psychological trauma is a major component of our damages claims. PTSD in children presents as sleep disturbance, academic regression, and persistent fear. We retain pediatric psychologists to quantify the emotional cost and the lifetime of therapy your child may need to regain their confidence.

The Attorney911 Moat: Why the Chains Fear Our Firm

When an Urban Air or Sky Zone franchisor sees “The Manginello Law Firm” on a demand letter, they know the case won’t be settled for pennies.

  1. We Know the Architecture: We don’t just sue the local LLC. We name the parent conglomerate and the private equity firm that approved the budget cuts.
  2. We Know the Medicine: From Salter-Harris to rhabdomyolysis, we speak the doctor’s language.
  3. We Know the Insurers: Lupe Peña’s background in insurance defense means we know exactly when an adjuster is bluffing about policy limits.
  4. We Know the Standards: We have memorized ASTM F2970 and EN ISO 23659:2022. We know the standards better than the park’s own managers.

City of Wichita Falls families deserve a firm that doesn’t back down. We have gone head-to-head with some of the largest companies in the world and won.

What happens in the next 72 hours will determine the next 70 years of your child’s life. Don’t leave it to chance. Don’t leave it to the park’s insurance adjuster.
