Hip fracture in the elderly – risks, mortality and recovery

---

A hip fracture is one of the most serious injuries an older person can sustain. The outlook depends on age, underlying health and how quickly help arrived – and recovery can take up to a year or more.

Why is a hip fracture so serious for older people?

A hip fracture is not simply a broken bone. For many older people, it marks a clear before and after – in mobility, independence and quality of life.

The reason is that older people often already have a more fragile baseline health. The surgery itself is demanding. Complications such as blood clots, pneumonia and delirium are common. And prolonged bed rest is harmful – it further weakens muscles, circulation and cognitive function.

Risk factors that worsen the outlook

Not every older person with a hip fracture has the same prognosis. The following factors increase the risk of serious consequences:

• Advanced age – the older the person, the greater the risk of complications
• Dementia or cognitive impairment – makes rehabilitation harder and increases confusion
• Heart disease, kidney failure or COPD
• Malnutrition and low muscle mass
• Previous falls and fractures
• Long time on the floor before help arrived

The last point is critical: every hour without help increases the risk of hypothermia, pressure sores and shock – and significantly worsens outcomes.

Mortality – what do the figures show?

Hip fracture carries significant mortality, particularly among the oldest and most frail:

• Around 10% of patients die within 30 days of surgery (1)
• Within one year, approximately 30% have died – most often from associated conditions, not the fracture itself
• Around 10% of those who lived at home before the fracture are unable to return
• Half of survivors experience lasting reduction in walking ability

The average age of a person with a hip fracture in the UK is 83–84 years (1).

Complications during and after treatment

The most common complications following a hip fracture in older people:

• Deep vein thrombosis or pulmonary embolism – a serious, life-threatening complication
• Pneumonia – common in patients who are immobile
• Urinary tract infection – increases with catheter use and reduced mobility
• Pressure sores – develop rapidly with immobility
• Delirium – affects a large proportion of older patients after hip surgery
• Depression and anxiety – underrecognised but common consequences

Recovery – how long does it take?

Rehabilitation begins the day after surgery, with physiotherapy and mobility exercises. The aim is for the person to bear weight and walk as soon as possible.

Typical timeline:

• Hospital stay: around 1–2 weeks (1)
• Inpatient rehabilitation or care home: 2–6 weeks
• Home rehabilitation: continues for months after discharge
• Full recovery: up to one year – and longer for femoral neck fractures

Some people recover fully. Others do not – half of patients experience a lasting reduction in mobility, and around 10% of those who previously lived independently are unable to return home.

The critical window – when help does not arrive in time

One of the most underestimated risk factors in hip fracture is not the surgery – it is what happens before the ambulance arrives. An older person who falls at home and cannot get up may not be able to reach the phone. Every hour that passes increases the risk of serious complications.

This is exactly when a personal alarm can make the difference between a quick rescue and hours on the floor. Automatic fall detection means the alarm triggers even if the person is unconscious or too weak to press a button.

Personal alarm for those at increased fall risk

Sensorem’s personal alarm is designed for people with an increased risk of falling. It can be triggered manually or automatically if the person falls, and calls pre-set contacts with two-way voice communication through the watch’s built-in speaker. It works outdoors and has built-in GPS positioning, so you can always see where the person is in the Sensorem app.
