Clinical Question

Whicholderwomen are athigh riskofhipfracture?

Evidence Summary

Approximatelyonein sixwomenwillhavea hip fracture during her lifetime, and

approximatelyonein35ofallwomenwilldie of complications from hip fracture.1Bonemineraldensityscreeningforwomenis recommended beginning at 65 years ofage,orat60yearsofageinthepresenceofriskfactorssuchaslowerbodymassindex,smoking, or long-term corticosteroid use.2However,lowbonemineraldensityisonlyone ofmany risk factors for hip fracture.Identifying women who are at high risk

allows a family physician to recommendadditionalmeasures thatmight reduce therisk of fracture such as exercise and bal-ance regimens,3 cessation of tobacco oralcoholuse,4andmodificationsofthehomeenvironment.5

Predicting Hip Fracture Risk in Older WomenMARKH.EBELL,MD,MS,Athens, Georgia

This guide is one in aseries that offers evidence-based tools to assist familyphysicians in improvingtheir decision making atthe point of care.

A collection of Point-of-Care Guides published inAFP is available at http://www.aafp.org/afp/poc.

The FRAMO (Fracture and Mortality)Index (Table 2), validated in 1,498 Swed-ishwomen,consistsoffouritemsusedinasimplescoringsystem.7Itidentifieslow-andhigh-risk groups and is a good predictor

ofoverallmortality and hip fracture risk.7

The Fracture Index (Table 3) is a six-itemrisk score with an optional seventh item(bone mineral density at the hip).6 Itwasdevelopedin7,782womenusingdatafromtheStudyofOsteoporoticFracturesandwasvalidatedinaseparategroupof7,575Frenchwomen.6
