Introduction
Hindfoot arthritis, also known as ankle arthritis, is a condition that affects the joints in the hindfoot, which includes the ankle joint and the subtalar joint. It is a form of osteoarthritis that occurs when the cartilage in the joints wears down over time, causing pain, stiffness, and limited mobility.
According to some studies, the prevalence of foot and ankle arthritis in general population ranges from 1 % to 4 %, with hindfoot arthritis being less common than arthritis of other parts of the foot. The incidence and prevalence also increase with age, with the highest rates found in individuals over 60. Women have higher chances than men to develop hindfoot arthritis. Additionally, underlying medical conditions such as diabetes or obesity can further increase the risk of developing arthritis in the feet.
What Are the Causes of Hindfoot Arthritis?
Hindfoot arthritis is a condition that develops over time and can be caused by various factors. Some common causes of hindfoot arthritis are as follows:
-
Trauma - A traumatic injury to the ankle joint can cause arthritis later in life. Fractures or dislocations of the ankle joint can damage the cartilage and cause it to wear down more quickly.
-
Genetics - In some cases, genetic predisposition to developing arthritis is more. A person with a family history of arthritis may be more likely to develop it themselves.
-
Wear and Tear - Over time, the cartilage in the ankle joint can wear down from regular use. This is particularly common in athletes or people who engage in activities that put a lot of stress on the ankle joint.
-
Inflammatory Conditions - Inflammatory conditions such as rheumatoid arthritis can also cause hindfoot arthritis. These conditions cause the body to attack its own joints, leading to inflammation and damage to the cartilage.
What Are the Symptoms of Hindfoot Arthritis?
Hindfoot arthritis can cause a range of symptoms that can impact daily activities. Here are some common symptoms of hindfoot arthritis:
-
Pain - Pain is the most common symptom of hindfoot arthritis. It may be felt in the ankle joint, the subtalar joint or both. The pain may be dull or sharp and can be aggravated by certain activities.
-
Stiffness - The joints may feel stiff, particularly in the morning or after periods of inactivity. This can make it difficult to move the foot up and down or side to side.
-
Swelling - The joints may be swollen or tender to touch. Swelling can make wearing shoes or putting weight on the affected foot difficult.
-
Limited Range of Motion - The range of motion in the ankle joint may be limited, making it difficult to move the foot up and down or side to side. This can impact activities such as walking, running, or climbing stairs.
How to Make a Diagnosis of Hindfoot Arthritis?
Diagnosing hindfoot arthritis involves a combination of a physical examination and diagnostic tests. The common methods used to diagnose hindfoot arthritis are as follows:
-
Physical Examination - During a physical examination, a healthcare provider will assess the affected foot for pain, swelling, and limited range of motion. They may also ask about symptoms and medical history.
-
X-rays -X-rays can help identify changes in the bones and joints of the foot. These changes may include bone spurs, narrowing joint space, and cartilage loss.
-
MRI (Magnetic Resonance Imaging) - An MRI uses magnetic fields and radio waves to produce detailed images of the foot. This can help identify damage to the soft tissues, such as ligaments, tendons, and cartilage.
-
CT (Computed Tomography) Scan - A CT scan uses X-rays and computer technology to produce cross-sectional images of the foot. This can help identify changes in bone structure and joint alignment.
What Are the Complications of Hindfoot Arthritis?
If left untreated, hindfoot arthritis can lead to several complications impacting daily activities and overall quality of life. Following are some of the common complications of hindfoot arthritis:
-
Joint Deformity - As hindfoot arthritis progresses, it can cause joint deformities such as bone spurs or joint erosion.
-
Reduced Mobility - Hindfoot arthritis can reduce mobility and make it difficult to perform daily activities such as walking, climbing stairs, or standing for long periods.
-
Chronic Pain - Hindfoot arthritis can cause chronic pain that can impact the overall quality of life. Pain may be constant or intermittent and can be aggravated by certain activities.
-
Depression and Anxiety - Chronic pain and reduced mobility can lead to depression and anxiety in some individuals. These conditions can further impact the quality of life and make it difficult to manage symptoms.
How Can Hindfoot Arthritis Be Prevented?
While hindfoot arthritis cannot always be prevented, there are some steps that individuals can take to reduce the risk of developing the condition. Here are some common prevention methods for hindfoot arthritis:
-
Maintain a Healthy Weight - Excess weight causes more stress on the feet and increases the chances of developing arthritis. A person should maintain a healthy weight and eat a balanced diet; regular exercise can help reduce this risk.
-
Wear Proper Footwear - Wearing proper fitted shoes with good arch support can help reduce stress on the joints of the feet. Avoid high heels, as these put additional stress on the feet.
-
Exercise Regularly - Regular exercise can help maintain flexibility and strengthen the muscles around the joints in the feet. Low-impact activities such as walking, cycling, or swimming are good options for individuals with arthritis.
-
Protect the Feet - Protecting your feet from injury can help reduce the risk of developing arthritis. Wear protective shoes when engaging in activities that can cause foot injuries, such as contact sports or manual labor.
Conclusion
Hindfoot arthritis can cause pain, swelling, and limited range of motion, impacting daily activities and overall quality of life. Diagnosis typically involves physical examination and diagnostic tests such as X-rays or MRIs. Treatment options include medication, physical therapy, assistive devices, and surgery. Complications of hindfoot arthritis can include joint deformity, reduced mobility, chronic pain, depression, and anxiety. Prevention methods such as maintaining a healthy weight, wearing proper footwear, exercising regularly, and protecting the feet can help reduce the risk of developing hindfoot arthritis.
