Evaulation of MR-ATVs (Rhinos) vs. Single Rider ATVs: Primary Amputation and Open Fracture Incidence

Rhinos, or multi-rider ATVs are associated with great risk of primary limb amputation and significantly higher incidence of open extremity fractures compared to single-rider vehicles.

Gregg Wendell Schellack, DO, a fifth-year orthopaedic resident at Loma Linda University in California, compared the injury differences between multi-rider ATVs and single-rider ATVs. A total of 110 patients were evaluated over a two-year period:

  • 39 injuries were multi-rider related; while 71 were single-rider related.
  • 64 percent of multi-rider related-injuries resulted in open fractures while 11 percent sustained open fractures on a single-rider ATV.
  • 44 percent of mr-atv operators sustained severe, limb threatening open fractures while none of the sr-atv operators sustained an open fracture of this severity.
  • 15 percent of multi-rider related injuries resulted in primary limb amputations while only 1 percent of single riders needed amputations.
  • The relative risk of amputation for MR ATV riders was 10.9 times higher than that of standard ATV riders.

Motocross Morbidity: Economic Cost and Injury Distribution in Children

A. Noelle Larson, MD, a Fellow in Pediatric Orthopaedics at Texas Scottish Rite Hospital, and co-authors at the Mayo Clinic found that pediatric motocross patients treated at a regional Level 1 trauma center sustained severe injuries, frequently required admission and surgical intervention, even though they were wearing helmets and safety equipment.

Both recreational and competitive motocross activities were included. Over a seven year period, 299 cases were noted in 249 patients, under the age of 17 years old:

  • the mean age of patient injured was 14.1 years;
  • 94 percent of patients were male;
  • 141 cases requi
