A 10-year-old girl pulled a quarter-zip sweatshirt over her head, and the zipper caught the skin of her left upper eyelid. Her family trimmed the sweatshirt away at home, leaving the zipper and a rim of fabric still clamped to her face; they tried unsuccessfully to remove it, and then drove her to a community pediatric emergency department in Ohio.
She was previously healthy and, by the time she arrived, calm. She reported no pain in the eye itself and no change in her vision, and felt discomfort only when someone moved the zipper. No analgesia had been attempted before she got there.
Nothing standard worked. Clinicians could not unzip it. Wire cutters failed. Bolt cutters failed. Prying the zipper’s faceplates apart failed. All of it happened millimeters from her eye, with the team shielding the globe and surrounding tissue throughout.
What finally freed her was a vibrating cast saw, the oscillating tool normally used to open plaster and fiberglass casts, applied to the zipper’s median bar. The case was reported by Arjun Sarin and Purva Grover of the Division of Pediatric Emergency Medicine at Cleveland Clinic Children’s and published in The Journal of Emergency Medicine in 2025.
Why a Zipper Is Harder to Beat Than It Looks
A zipper is not one mechanism. It is teeth, a slider with two faceplates, and a median bar running between them, and freeing trapped skin depends entirely on which part is doing the trapping.
The classic emergency maneuver is the median bar technique: cut the bar that holds the slider’s two plates together and the whole assembly falls apart, releasing whatever is caught. It usually takes seconds. A 2024 simulation study using chicken skin found a median time to release of 26.4 seconds with that method and a 95.5 percent success rate.
The problem in this case was hardware, not technique. The median bar was there, and the team knew to target it. They simply could not cut through it with the tools in the department. A cast saw could. To the authors’ knowledge, it was the first report of a cast saw being used successfully in a pediatric emergency department to free zipper-entrapped skin.
That is a useful piece of institutional knowledge, since cast saws already sit in most emergency departments.
The unfamiliarity is well documented. Zipper entrapment shows up rarely enough that emergency medicine educators have built a simulation trainer for residents specifically so learners can practice release techniques on a model before meeting a real case.
Eyelids Are the Rare Version of a Common Injury
Zipper entrapment is not exotic. It is just usually somewhere else. In children, the overwhelming majority of reported cases involve penile or scrotal skin, typically caught while pulling trousers up.
One pediatric emergency report put the incidence at roughly one in 4,000 among emergency patients aged 2 to 12 in a published case series, and noted that most were managed without general anesthesia. That same report, describing an 8-year-old girl whose right upper eyelid was caught, identified only two prior pediatric eyelid zipper cases in the literature at the time.
Approaches to eyelid cases have varied widely, which tells you something about how unfamiliar they are. One team freed a child’s eyelid with mineral oil lubrication and by cutting the fabric tape alongside the teeth to release tension. Another used lidocaine gel, which lubricates and anesthetizes at the same time. Reports elsewhere describe intranasal fentanyl for analgesia during the procedure.
Genital cases can still escalate. A case published in BMC Pediatrics in March 2026 described a 10-year-old boy in Ethiopia whose penile zipper entrapment required emergency circumcision after lubricants and local anesthesia failed, in a hospital where the cutting instruments and general anesthesia normally used for these cases were unavailable.
The Clock Is the Actual Risk
The injury itself is usually minor. The complication risk comes from how long the tissue stays compressed.
Prolonged entrapment can produce swelling, tissue damage and, in genital cases, urethral involvement or skin loss. That is why the emergency literature treats these as time-sensitive despite their low drama. The authors of the Cleveland Clinic report note that entrapment, though infrequent, carries potential for significant pain and injury, particularly if prolonged.
For the eyelid specifically, the added hazard is proximity. Every cutting attempt is happening next to a globe, which is why protecting the eye is a standing requirement in these cases and why home attempts are a bad idea. The authors also make a point about setting: large academic centers may have subspecialists on site, while most community emergency departments have single-physician coverage and no one to call in person.
In this instance, the girl’s family had already tried at home before arriving. That is common and understandable, and it also lengthens the compression time.
What Parents Can Reasonably Take Away
This is one patient, and no single case establishes a best technique. It does not mean a cast saw is now the recommended tool, only that it worked when several others did not.
The practical guidance is unglamorous. If a zipper traps skin anywhere, especially near the eye, do not keep pulling, cutting or prying. Repeated attempts add compression time and increase the risk of tearing tissue. Emergency clinicians have several release techniques and the equipment to protect the eye while using them.
Trimming the garment away, as this family did, is reasonable if it reduces tension and makes transport easier, but it does not solve the problem and should not delay the trip. Anyone whose child has an eye or eyelid involved should be evaluated in an emergency department rather than waiting to see whether it works itself loose.
Key Questions Answered
What happened to the girl?
Her left upper eyelid skin was caught in the zipper of a quarter-zip sweatshirt while she was putting it on. Emergency clinicians freed her using a vibrating cast saw after several other methods failed.
Why did wire and bolt cutters not work?
The team targeted the correct part, the zipper’s median bar, but could not cut through it with the cutters available. The cast saw could.
Is a cast saw now the standard treatment?
No. This is a single case report. Standard approaches include the median bar technique, lubrication with mineral oil or lidocaine gel, and cutting the fabric tape to release tension.
How common is zipper entrapment in children?
One pediatric emergency report cited an incidence of roughly one in 4,000 among emergency patients aged 2 to 12. Most cases involve penile or scrotal skin, and eyelid cases are rare.
Should parents try to free the skin at home?
No. Repeated pulling, cutting or prying adds compression time and risks tearing tissue. Trimming excess garment to reduce tension is reasonable, but it should not delay going to an emergency department.
