Hip Fractures

What are Hip Fractures

A hip fracture refers to a break in the hip bone. It typically occurs in the upper part of the femur or thigh bone. They are frequently observed in older individuals and those with conditions that weaken bone structure like osteoporosis.

The nature of the break can vary; it may be a complete break, where the bone is broken all the way through, or an incomplete break, where only a small piece of the bone is broken.

Types of Hip Fractures

Hip fractures can be classified based on their location on the femur bone. The most common types are:

Femoral Neck Fracture

This type of fracture occurs in the femoral neck, a part of the thigh bone located just below the ball of the hip joint. Femoral neck fractures are often seen in older individuals.

Intertrochanteric Fracture

This fracture occurs between the femoral neck and the shaft of the femur, in a region known as the intertrochanteric area. It involves the part of the thigh bone that forms part of the hip joint.

Stable and Unstable Fractures

During diagnosis, hip fractures can also be categorised based on their stability. Stable fractures, where the bones have not moved out of place, can sometimes be treated non-surgically. Unstable fractures, where the bones have shifted, typically require surgical intervention to repair and stabilise the broken bone for proper healing.

Symptoms

The identification of a hip fracture is typically guided by specific symptoms, which include:

• Pain: Patients with a hip fracture often experience acute pain, which is usually concentrated in the groin or the upper thigh area. The pain from a hip fracture may radiate along the inner thigh, potentially reaching as far as the knee.
• Limited Mobility: Patients may find it challenging to put weight on the leg on the side of the injured hip, which can impede their ability to walk or stand.
• Bruising, Swelling and Other Physical Changes: Observable physical changes often accompany a hip fracture. These can include bruising and swelling around the hip area. In some cases, the affected leg may appear shorter than the other, or the leg on the injured side may turn outward.
• Inability to Bear Weight: A common and telling symptom of a hip fracture is the inability to bear weight on the leg on the affected side. This may manifest as an inability to get up from a fall or to walk without assistance.

Causes and Risk Factors

Hip fractures are influenced by various causes and risk factors, which include:

• Falls
  The most common cause of hip fractures is falling, especially in older adults. These falls often occur from standing height or less. In individuals with severely weakened bones, minor stress like standing or twisting can result in fractures.
• High-Impact Trauma
  In younger individuals or those with stronger bone density, hip fractures are more likely to result from high-impact trauma, such as a car crash or a severe fall.
• Age-Related Degeneration
  Age is a factor, with the risk of hip fractures increasing as individuals age. This increase is primarily due to the natural weakening of bones and an increased likelihood of falls.
• Women Post-Menopause
  Post-menopausal women have an increased risk of hip fractures due to hormonal changes that lead to a more rapid decrease in bone density compared to men.
• Unhealthy Lifestyle and Health Choices
  Sedentary lifestyles, excessive alcohol consumption, and certain medications that affect balance or bone strength can increase the risk of hip fractures.
• Osteoporosis
  This condition, characterised by weakened and porous bones, can raise the risk of fractures.
• Nutritional DeficienciesCalcium and vitamin D are necessary for bone health. Inadequate amounts of these can contribute to an increased risk of hip fractures.This condition, characterised by weakened and porous bones, can raise the risk of fractures.

Non-Surgical Treatment Options

Non-surgical treatment may be considered for hip fractures under certain conditions, particularly when surgery poses a high risk due to the patient’s health status.

Pain Medication

Pain management medications may include analgesics to alleviate pain and anti-inflammatory drugs to reduce swelling.

Physical Therapy

Physical therapy, guided by the hip specialist, can provide targeted treatment and symptom relief. It aims to enhance mobility, strengthen muscles around the hip, and improve overall function.

Assistive Devices

The use of walking aids, such as canes or walkers, may be recommended to assist with mobility and reduce the load on the injured hip.

Surgical Treatment Options

Surgical intervention is often required for hip fractures, especially in cases of unstable fractures.

• Internal Fixation
  This involves using metal screws, nails, or plates to hold the fractured bones in place, allowing them to heal properly. This method is often used for fractures that have not moved severely out of place.
• Hip Replacement Surgery
  In cases where the hip joint is damaged, a partial or total hip replacement may be performed. This involves replacing the damaged parts of the hip joint with artificial components.
• Hemiarthroplasty
  This is a type of partial hip replacement where only the femoral head (the ball part of the joint) is replaced. It is commonly chosen for certain types of femoral neck fractures.

Prevention Strategies

Preventing hip fractures, particularly in high-risk groups like the elderly, involves several strategies:

• Diet and Exercise to Maintain Bone Density: Consume a diet rich in calcium and vitamin D to maintain bone health. Supplements may be recommended for individuals at risk of deficiencies. Regular weight-bearing exercises, like walking or jogging, also help build up bone strength.
• Implementing Fall Prevention Measures: Implement safety measures in the home to prevent falls. This includes removing tripping hazards, ensuring adequate lighting, and installing handrails in necessary areas.
• Avoiding Unhealthy Lifestyle Choices: Avoid tobacco and limit alcohol intake as both can negatively affect bone density.
• Maintaining a Healthy Weight: Maintaining a healthy weight also reduces the strain on bones.
• Regular Health Check-Ups: Regular medical check-ups can help in the early detection of conditions like osteoporosis that increase the risk of fractures. Medications contributing to bone loss or balance issues should be reviewed and adjusted if necessary.
