Injuries in Emerging Sports

Case 1
• Competitive cheerleader• Pedicle stress fracture
LaBella CR, Mjaanes J; Council on Sports Medicine and Fitness. Cheerleading injuries: epidemiology and recommendations for prevention. Pediatrics. 2012 Nov;130(5):966-71.
Competitive Cheerleading
• Lower overall injury rate than gymnastics, but higher catastrophic injury rate• Approximately 66% of all catastrophic injuries in high school girl
athletes over the past 25 years were from cheerleading
Pedicle stress fractures
• Many cases of pedicle fracture are associated with osteoporosis, trauma or prior surgery• May be more common in cases with contralateral unilateral
spondylolysis, or may just have pedicle sclerosis
Imaging
• X-rays insensitive• Bone scan with SPECT is sensitive, but radiation concerns especially
for young athletes• MRI may be equally sensitive, and can identify bony edema• CT may be better to follow fracture healing, if needed
Treatment
• Similar to pars fracture, but even longer rest is likely required (up to 6 months)
Case 2
• Parkour• Hip flexor tendonitis
Parkour
• Free running, art of movement, urban gymnastics, obstacle coursing
Parkour
• Injuries• German survey: 70% skin abrasions, muscle injury 13%• Few case reports• Clavicle fx, bilat distal radius fx, distal tib/fib fracture, bilateral calcaneal
fracture, multiple midfoot fractures• C4/5 subluxation and locked facets resulting in death
• Beginners may try moves they have seen in videos, without proper training
Parkour
• Landings• Traditional: toe-heel landing• Parkour precision: forefoot only, arms counterbalance movement• Parkour roll: shoulder roll in the direction of travel
• Both parkour landings have shown decreased maximum ground reaction force, increased time to maximum force and lower landing rates than traditional landings• This may decrease risk for injury
Puddle DL, Maulder PS. Ground reaction forces and loading rates associated with parkour and traditional drop landing
techniques. J Sports Sci Med. 2013 Mar 1;12(1):122-9.
Traditional landing
Parkour precision technique
Parkour roll technique
Parkour
• Athletes should master moves in a controlled environment with padded landings before trialing outside• Many professionals have training in gymnastics or martial arts• Amateurs should not attempt high level acrobatics
• Fractures are the most common reported injury in the literature, but more serious injuries can occur
