Functional recovery following a second hip fracture

Area of Science:

• Orthopedics
• Geriatrics
• Epidemiology

Background:

• Hip fractures pose a significant risk for contralateral hip fracture, a concern amplified by increasing life expectancy.
• Existing literature inadequately addresses the risk and implications of bilateral hip fractures.

Purpose of the Study:

• To investigate the epidemiological characteristics of bilateral hip fractures.
• To analyze post-operative limb function and functional autonomy in patients with bilateral hip fractures.

Main Methods:

• Retrospective analysis of 2,771 patients over 50 years old with proximal femur fractures over 9 years.
• Data collected included fracture laterality, age, sex, pre-trauma physical activity (MET scale), trauma severity, fracture site, surgery type, and discharge functional autonomy (FIM scale).

Main Results:

• Bilateral fractures occurred in 7.58% of patients, predominantly in women over 85 years old (female to male ratio 1:7.08).
• Domestic falls were the most common cause for both unilateral and bilateral fractures.
• Patients with bilateral fractures experienced a significant reduction in functional autonomy (mean FIM score difference of 16.77) and a threefold increase in non-ambulatory status.

Conclusions:

• Bilateral femur neck fractures are infrequent but disproportionately affect sedentary elderly women.
• The rise in the aging population suggests bilateral hip fractures may become a significant issue.
• A drastic decline in functional autonomy post-fracture necessitates improved fall prevention strategies and extended rehabilitation programs.
