Hip Fracture Prevention / Hip Protectors Primer / Science and Clinical Studies / Fall Prevention
Hip protector research, Hip Protectors, the value of Hip Protectors in an acute setting, Fall Prevention in Hospitals and Institutions: Hip fractures (as a result of falls / osteoporosis / bone loss) are a major and growing socio-economic problem in the US. More than 90% of hip fractures are related to a direct impact to the hip, and hip protector ("padding") systems have been introduced as a concept in the prevention of these fractures.
300,000 Hip Fractures in the US alone per Year
Several clinical studies have been carried out with hip protectors (protection of the greater trochanter). The goal of these studies has been to confirm/disapprove efficacy (reduction in the the number of hip fractures), clarify patient compliance ("willingness" of patients to wear hip protectors), and establish the health-economic benefit from the use of hip protectors. | Hip Protector use in the community.
The general effect of hip protectors (in particular of impact diverting hip protectors) has been proven in various biomechanical studies. Laboratory experiments have shown it is possible to reduce impact force on the greater trochanter with the use of shell type protectors and horse-shoe shaped protectors. Soft hip protectors may offer a lower reduction of the peak force.
In total over 4,000 patients have been studied. Studies of hip protectors have been carried out in different care settings; nursing homes, assisted living facilities, home care, hospitals and people living at home.
Patient compliance varies greatly in the studies and is dependent on factors such as; "a previous hip fracture", "fear of falling" and "snowy weather".

Douglas P. Kiel (2007), Jay Magaziner, Sheryl Zimmerman, Linda Ball, Bruce A. Barton, Kathleen M. Brown, Judith P. Stone, Dawn Dewkett, Stanley J. Birge.
Findings: Clinical controlled, but not randomised study of elderly 1,684 inpatients predominantly coming from their own homes. The users of the shell type hip protectors experienced a relative risk of sustaining a hip fracture of 88% (difference not statisticaly significant).
Findings: Randomised and controlled trial of 11 months duration including 745 nursing home residents a relative risk of 0.33, when adjusting for sex and age. In the control group of 442 residents 17 hip fractures were recorded compared to 4 hip fractures in the intervention group of 302 residents.
Hip protectors were made of stiff shells placed in pockets of special made underwear.
Findings: Randomised controlled trial of 11 months duration including 665 nursing home residents (444 women, 121 men) that the risk of suffering a hip fracture was reduced to 43% in the intervention group, and none hip fracture occurred while wearing the protectors.
Hip protectors were made of silicone pads.
Findings: No hip fractures in 16 protected falls compared to 4 hip fractures in 7 unprotected falls. Results were based on fall registration in a non-randomised and not controlled nursing home study.
Hip protection systems (Hip Protectors / Hip Pads) may be a factor in the prevention of hip fractures. A percentage of hip fractures theoretically may be preventable but poor patient compliance and other factors brings down the number of actual reduction of hip fractures. Even a minor reduction in the occurrence of hip fractures should have positive economic impact. When wearing a hip protector, one cannot exclude the possibility of sustaining a hip fracture.
