Why Older Adults Are More Susceptible to Fractures
Age-related bone loss, a primary driver of fracture risk, is known as osteoporosis. This condition weakens bones, making them brittle and more likely to break from even minor incidents, often called fragility fractures. For older adults, many factors combine to increase this risk, including reduced muscle mass and strength (sarcopenia), impaired vision, balance problems, and slower reflexes, all of which increase the likelihood of falls. Furthermore, certain medications can cause dizziness or affect bone density, compounding the risk.
The Most Common Fractures in Older Adults
Hip Fractures
Regarded as one of the most serious fractures, hip fractures are most common in adults over 65, with 90% occurring in this age group. The vast majority are the result of a fall from a standing height. For those with severe osteoporosis, a hip fracture can happen with no fall at all, just by twisting the leg or standing awkwardly. Hip fractures often require major surgery and intensive rehabilitation, and carry a high rate of complications, impacting mobility and independence.
Symptoms of a hip fracture include:
- Severe pain in the hip or groin
- Inability to bear weight on the affected leg
- The injured leg may appear shorter or be externally rotated
Vertebral Compression Fractures
Vertebral compression fractures (VCFs) are breaks in the bones of the spine (vertebrae). These are also strongly linked to osteoporosis and can occur with minimal trauma, sometimes simply from coughing, sneezing, or lifting a light object. Because they can cause only mild or gradual back pain, about two-thirds of VCFs go undiagnosed. However, multiple VCFs over time can lead to significant height loss and a hunched posture known as kyphosis.
Symptoms of a VCF include:
- Sudden onset of back pain
- Increased pain when standing or walking, relieved by lying down
- Loss of height
- Stooped posture
Distal Radius (Wrist) Fractures
The distal radius fracture, or broken wrist, is particularly common in women over 50. It often happens when a person falls onto an outstretched hand (FOOSH). While generally less devastating than hip fractures, a wrist fracture can still lead to long-term issues, especially if alignment is not properly maintained during healing. This can significantly disrupt daily activities and a person's ability to live independently.
Symptoms of a wrist fracture include:
- Sudden pain and swelling
- Deformity, sometimes described as a “dinner fork” shape
- Difficulty moving the fingers or wrist
Fracture Risk Factors and Prevention Strategies
Preventing fractures in older adults involves a multi-pronged approach that addresses both bone density and fall risk.
For Healthy Bones:
- Proper Nutrition: Ensure adequate intake of calcium and vitamin D through diet and supplements. This is crucial for maintaining bone density.
- Regular Exercise: Engage in weight-bearing exercises like walking, jogging, and weightlifting to help build and maintain bone mass. Balance training, such as Tai Chi, is also highly effective at preventing falls.
- Medical Management: Undergo bone density screenings as recommended by a physician, especially for women over 65 and men over 70. Medications for osteoporosis may be necessary.
For Fall Prevention:
- Home Safety Modifications: Secure or remove loose rugs, install grab bars in bathrooms, and ensure adequate lighting in hallways and stairwells.
- Regular Health Check-ups: Have vision and hearing checked regularly and discuss any medications that may cause dizziness or imbalance with a doctor.
- Choose Proper Footwear: Wear sturdy, low-heeled shoes with good traction and avoid walking in socks or flimsy slippers.
Treatment Options Comparison
While specific treatment varies by the type and severity of the fracture, here is a general comparison of surgical versus non-surgical options, especially relevant for distal radius and hip fractures where choices exist.
Feature | Non-Surgical Treatment | Surgical Treatment |
---|---|---|
Application | Suitable for stable fractures with minimal displacement. Often involves a cast, splint, or brace. | Necessary for unstable, displaced, or complex fractures. Common for most hip fractures. |
Speed of Recovery | Can take longer to regain full function due to prolonged immobilization. | Can lead to faster return to daily activities and better early-stage function, especially for wrist fractures. |
Accuracy of Reduction | Risk of malunion (improper healing), which can cause cosmetic deformity and potentially long-term functional issues. | Allows for precise realignment and stabilization of bone fragments using pins, plates, or screws. |
Risks | Lower risk of complications associated with anesthesia and infection. | Potential risks include infection, nerve injury, and complications from anesthesia. |
Best for | Lower-demand patients or those with stable, simple fractures. | High-demand patients, those with complex fractures, or if rapid recovery of function is a priority. |
Rehabilitation is Key to Recovery
After initial treatment, rehabilitation is a critical step for older adults to regain strength, balance, and independence. For hip fractures, rehabilitation begins almost immediately in the hospital to prevent complications and restore mobility as quickly as possible. Physical therapy focuses on gait training and strengthening exercises. For wrist and vertebral fractures, a regimen of physical and occupational therapy helps improve range of motion, build muscle strength, and adapt to any functional limitations.
Successful recovery also depends on addressing the underlying causes of the fracture. For example, if osteoporosis is a factor, a comprehensive care plan will include medication, nutrition counseling, and ongoing fall prevention strategies to reduce the risk of future breaks. Family physicians and caregivers play a vital role in identifying risk factors and ensuring that older adults receive appropriate preventative care and follow-up.
In conclusion, older adults are at increased risk for several specific types of fractures due to reduced bone density and a higher incidence of falls. Hip, vertebral, and wrist fractures are the most common and can have a significant impact on quality of life. By focusing on robust bone health and active fall prevention, older adults and their caregivers can significantly reduce the risk of these debilitating injuries and maintain long-term independence.
