Dementia and hip fractures / 中华创伤骨科杂志

ABSTRACT

Dementia,with a poor outcome,is a syndrome characterized by persistent impairment in cognitive function or behavioral abnormalities as evidenced by deficits in memory,attention,language,and motor activity.Hip fractures represent a widespread morbidity among the geriatric population,and fall is the main cause of osteoporotic fracture.The mortality after hip fracture reaches from 20％ to 40％ within one year after operation.Co-occurrence of dementia and hip fracture is a common challenge for orthopedic surgeons and other clinicians involved in hip fracture care.Until recently,dementia in patients with hip fracture has been an issue that has received scant recognition compared with conditions considered to represent a more immediate threat to life,such as cardiopulmonary and thromboembolic diseases.This article reviews the current issues and available evidence concerning dementia in patients with hip fracture.
