Objective: To describe the estimated frequency and types of injuries a
ssociated with in-line skates in U.S. children and to compare in-line
skating injuries to rollerskating injuries, Design: National case seri
es. Setting: Emergency departments of hospitals participating in the U
nited States Consumer Product Safety Commission (USCPSC) National Elec
tronic Injury Surveillance System. Patients: Persons with injuries ass
ociated with the use of inline skates or rollerskates reported to the
USCPSC in 1992 and 1993. Results: There were an estimated 66,465 injur
ies associated with in-line skates; the incidence of injury was highes
t in children 11 and 12 years old, An estimated 40,730 in-line skate i
njuries involved children <20 years old, The mean age of injured child
ren was 11.8 years (median, 12 years); 68% were boys. Fractures (45%)
were the most common injury; 66% of fractures involved the distal fore
arm. Five percent had head injuries. Two and one half percent required
hospital admission; 90% of children admitted had a fracture and 11% h
ad a head or face injury. There were an estimated 147,928 rollerskatin
g injuries among children <20 years old; the mean age was 10.5 years (
median 10 years) (P < 0.001 vs in-line skates), Thirty-two percent wer
e to boys (P < 0.001 vs in-line skates), Fractures were the most commo
n injury; forearm fractures accounted for 72% (P < 0.001. vs in-line s
kates). Five percent had head injuries. One and one half percent were
admitted to the hospital (P < 0.001 vs in-line skates). In 1993, the i
njury rate among children for in-line skates was 31/100,000, and the i
njury rate for rollerskates was 95/100,000. Conclusions: Injuries asso
ciated with in-line skates are highest among preadolescents. Injuries
associated with in-line skate use are less common than injuries associ
ated with rollerskate use. Distal forearm fractures are the most commo
n injuries related to both in-line skate and rollerskate use. Exposure
data and analysis of the efficacy of protective gear, including wrist
guards and helmets, are needed.
