Sideways falls that impact the hip are the primary cause of hip fractures. Most, although not all studies support the use of hip protectors to prevent hip fractures in high-risk individuals.

Hip protectors are most useful in very frail people and are somewhat bulky; they are most studied in supervised settings such as nursing homes but can also be used in home care.

The newest models include an elastic undergarment with side pockets for the protective padding and several models are available.
