Limping: Causes, Types, and Treatment Methods to Restore Normal Movement

Limping is a common problem that affects many people, impacting their movement and daily life. It can be caused by an injury, inflammation, nerve issues, or even bone abnormalities. While it can be painful and frustrating, there are many ways to treat it, including medications, exercises, and even surgery in some cases. In this Dalili Medical article, we will discuss the types of limping, its causes, and the best treatment options to help you walk comfortably without pain!

What is Claudication?

Claudication is pain in the thigh, calf, or buttock that occurs when walking and causes difficulty in movement. It happens when the arteries become narrow or blocked, reducing blood flow to the legs.

Initially, the pain appears after walking a certain distance and disappears with rest. However, over time, the condition may worsen, and the pain can occur even after walking shorter distances. In severe cases, a person may be unable to walk due to intense pain.

There are two main types of claudication:

• Vascular claudication: Usually a symptom of a serious problem with blood flow, such as peripheral artery disease (PAD).
• Neurogenic claudication: Caused by issues related to the spine and nervous system.

Causes of Claudication

Peripheral Artery Disease (PAD)

The most common cause of claudication is peripheral artery disease (PAD), a condition in which the arteries supplying blood to the limbs become narrow, usually due to atherosclerosis. Atherosclerosis occurs when fatty deposits (plaques) build up in the walls of the arteries, reducing blood flow to the limbs.

Other Contributing Factors to Claudication

• Smoking: Increases the risk of atherosclerosis and peripheral artery disease, affecting blood flow.
• Diabetes: High blood sugar levels can damage blood vessels and contribute to the development of arterial diseases.
• High cholesterol: Fat accumulation in the arteries reduces blood flow and increases the risk of claudication.
• High blood pressure: Can damage arteries, making them more prone to atherosclerosis.
• Obesity: Excess weight increases the risk of peripheral artery disease, leading to claudication.

Pain and Injuries in the Foot, Leg, or Hip

Injuries such as bone fractures, sprains from sports, or accidents (e.g., car crashes) can cause claudication. When a person sustains an injury, they may instinctively shift their weight to the uninjured leg or adjust their upper body movement without realizing it to reduce pressure on the affected limb. Overuse injuries and trauma are common causes of pain and claudication.

Congenital Deformities

Some people are born with skeletal or muscular abnormalities, such as a noticeable leg length discrepancy, which can affect their walking pattern.

Arthritis

One of the most common causes of pain in older adults is arthritis, which leads to joint pain and stiffness. If a person already has claudication, arthritis may worsen it.

Inflammation of Tendons and Ligaments in the Leg

Any inflammation or infection in the tendons or ligaments can weaken the leg muscles, potentially causing claudication.

Genetic Conditions

Some inherited diseases, such as muscular dystrophy, can lead to muscle weakness in the hips and legs, resulting in claudication.

Spinal Cord Compression

Pressure on the spinal cord due to injury or degenerative diseases associated with aging can cause leg and foot muscle weakness, leading to claudication.

Neurological Conditions

Any disorder affecting the brain, spinal cord, or peripheral nerves can impact walking since normal movement relies on the nervous system. If claudication suddenly appears in an elderly person, a doctor should evaluate the underlying cause.

Psychological Disorders

In some cases, claudication or changes in walking patterns may be related to psychological conditions.

Medications

Certain medications can have side effects that impact muscles or nerves, leading to claudication.

 

 

Other Causes of Claudication

There are additional causes of claudication, including:

• A lump or tumor in the leg
• Legg-Calvé-Perthes disease: A condition that temporarily restricts blood supply to the hip bone.
• Heart and lung diseases: These can affect walking due to overall body weakness.
• Testicular torsion: Can cause pain and discomfort, affecting walking.

Types of Claudication and Their Causes

Claudication is not a disease itself but a symptom of an underlying health condition that affects walking. There are different types of claudication, classified based on their root cause.

Structural Claudication (Anatomical Claudication)

Occurs due to bone or joint abnormalities, such as:

• Leg length discrepancy (one leg being shorter than the other).
• Congenital deformities, such as developmental hip dysplasia.
• Spinal misalignment, like scoliosis (curved spine).

Treatment: May include orthopedic shoes, physical therapy, or surgery, depending on the severity.

Pain-Induced Claudication (Antalgic Claudication)

Happens when a person avoids putting weight on the affected leg due to pain.

Common Causes:

• Arthritis (such as osteoarthritis or rheumatoid arthritis).
• Injuries (bruises, fractures, ligament sprains).
• Infections in bones or joints (such as osteomyelitis).

Treatment: Depends on the underlying cause and may include pain relievers, physical therapy, and rest.

Neurological Claudication (Nerve-Related Claudication)

Occurs due to muscle weakness or paralysis affecting walking.

Common Causes:

• Stroke.
• Multiple sclerosis (MS).
• Sciatic nerve paralysis (sciatica).
• Diabetic neuropathy.

Treatment: Focuses on addressing the neurological disorder and may include physical therapy, medications, and electrical muscle stimulation.

Vascular Claudication (Intermittent Claudication)

Occurs when reduced blood supply to the legs during walking leads to pain.

Common Causes:

• Peripheral artery disease (PAD) due to atherosclerosis.
• Blood clots in the legs.

Treatment: Includes vasodilators, anticoagulants, and managing cholesterol and blood pressure.

Psychogenic Claudication (Functional or Hysterical Claudication)

Happens without a clear physical cause and is often associated with psychological conditions such as:

• Conversion disorder.
• Severe anxiety or stress.

Treatment: Focuses on psychotherapy and emotional support to improve the condition.

 

 

Causes of Claudication in Children

1- Infections and Inflammatory Diseases

These are among the most common causes of claudication in children:

• Bacterial infections: Bacteria can settle in growing bones or nearby joints, causing severe pain and claudication, especially in younger children.
• Juvenile arthritis: Can cause pain, swelling, and difficulty moving, leading to claudication.
• Viral synovitis: Some viral infections cause temporary joint inflammation, resulting in claudication.

Rare Causes of Claudication in Children

• Tumors: Some tumors in bones or soft tissues can cause persistent pain and claudication in children.
• Congenital deformities: Conditions present at birth, such as developmental hip dysplasia, can lead to leg length discrepancies, which become noticeable when the child starts walking.
• Legg-Calvé-Perthes disease: A condition that reduces blood supply to the hip bone, causing the femoral head to flatten instead of remaining round.
  • Most commonly occurs in healthy children between the ages of 4 and 10.
• Slipped Capital Femoral Epiphysis (SCFE):
  • Happens when the ball of the hip joint slips off the femur due to weakness in the growth plate.
  • Typically appears between ages 9 and 15, just before puberty.
• Discitis (Spinal Disc Inflammation):
  • Inflammation of the discs between the vertebrae can cause claudication in children.
• Neurological disorders:
  • Some nervous system diseases cause muscle weakness or stiffness, affecting walking and leading to claudication.

Types of Claudication in Children

Based on the underlying cause and clinical presentation, claudication in children can be classified into several types:

1- Mechanical Claudication

• Occurs due to direct injuries such as wounds, fractures, or sprains, affecting the child's ability to walk normally.
• May also be caused by congenital bone or joint abnormalities, leading to foot or ankle instability.

2- Vascular Claudication (Intermittent Claudication)

• Occurs due to reduced blood flow to the legs, causing pain or discomfort while walking.
• The child may experience pain after walking short distances due to inadequate blood supply.

3- Neurological Claudication

• Caused by nerve problems that control leg and foot movement.
• Possible causes include:
  • Nerve compression (e.g., herniated disc).
  • Diabetic neuropathy, which can lead to weakness and loss of sensation in the foot.

4- Muscular Claudication

• Happens when the leg or foot muscles are too weak to support body weight while walking, causing imbalance and claudication.

5- Bone-Related Claudication

• Results from bone formation disorders or growth abnormalities, which impair the bones' ability to support the body properly during walking.

Difference Between Vascular and Neurological Claudication

Type	Main Cause	Key Symptoms	When Does Pain Occur?
Vascular Claudication	Poor blood flow to the limbs due to narrowed or blocked arteries	Pain, burning sensation, or fatigue in the legs while walking	After walking a short distance, relieved with rest
Neurological Claudication	Nerve compression or peripheral nerve damage	Muscle weakness, numbness, or tingling in the leg	May occur even at rest and worsens with movement

A comprehensive medical evaluation by a specialist is necessary to accurately diagnose the type of claudication and determine the appropriate treatment.

 

 

 

Diagnosis of Claudication

1- Medical History and Physical Examination

The doctor begins by discussing the patient's medical history, including:

• Symptoms: Pain, fatigue, or swelling.
• Risk Factors: Diabetes, smoking, high blood pressure.
• Lifestyle and Physical Activity Levels.

During the Physical Examination, the Doctor Checks for:

• Weak pulses in the legs, indicating poor blood flow.
• Non-healing wounds, which may suggest arterial blockage.
• Skin discoloration or cold feet, which could signal vascular problems.

2- Diagnostic Tests for Claudication

Ankle-Brachial Index (ABI)

• Compares blood pressure in the ankle and arm.
• Lower pressure in the ankle indicates artery blockages and poor circulation.

Doppler Ultrasound

• Non-invasive test that uses sound waves to visualize blood flow and detect blockages.

Angiography (X-ray or Magnetic Resonance Angiography - MRA)

• Contrast dye is injected into blood vessels to highlight blockages.
• Used to determine the severity of Peripheral Artery Disease (PAD).

Magnetic Resonance Imaging (MRI)

• Provides detailed images of blood vessels, muscles, and nerves to determine the cause of claudication, especially in neurological cases.

Diagnosis of Claudication in Children

Medical History Review

The doctor asks about:

• Recent infections or illnesses, such as cough or skin rashes.
• Family history of joint diseases, like rheumatoid arthritis.
• Recent falls or injuries that might cause limping.

Physical Examination

The doctor observes the child's walking pattern:

• Leaning on one leg may indicate hip pain.
• Spending less time on one foot suggests leg pain.

Additional Checks:

• Joints for swelling or restricted movement.
• Spine for scoliosis or stiffness.
• Foot abnormalities, such as high arches or claw toes.

3. Limping Due to Muscle or Bone Injuries (Fractures, Sprains, Bruises)

• Pain relievers such as Paracetamol or Ibuprofen.
• Muscle relaxants in case of severe spasms.
• Braces or splints if immobilization is necessary.

4. Limping Due to Vascular Problems (Intermittent Claudication Due to Poor Blood Circulation)

• Vasodilators like Cilostazol to improve blood flow.
• Anticoagulants such as Aspirin or Clopidogrel to prevent blood clots.
• Cholesterol-lowering drugs (statins) like Atorvastatin to reduce fat buildup in the arteries.

5. Neurological Limping (e.g., Herniated Disc or Diabetic Neuropathy)

• Nerve pain medications like Gabapentin or Pregabalin.
• Neuropathic pain relievers, such as tricyclic antidepressants (Amitriptyline).
• NSAIDs or Corticosteroids in severe cases.

⚠️ If limping persists or pain worsens, a doctor's consultation is necessary to determine the appropriate treatment for the child's condition.

 

When Should You See a Doctor?

You should visit a doctor in the following cases:

• If the limping is severe and does not improve with rest or home treatment.
• If the limping persists for a long time without noticeable improvement.
• If there is swelling, redness, or warmth in the affected area, as this may indicate an infection.
• If the child experiences numbness or loss of sensation in their leg.
• If the limping occurs after a fall or major injury, to rule out fractures or serious issues.
• If the child has difficulty moving their leg or experiences joint stiffness.
• If the limping is accompanied by fever or weight loss, as this could indicate a more serious underlying condition.

In these cases, a doctor should be consulted to determine the exact cause and provide appropriate treatment.

Which Specialist Should You See?

The right specialist for treating limping depends on the underlying cause and may include:

• Orthopedic surgeon – for injuries, joint problems, and structural disorders.
• Vascular specialist – if the limping is due to blood circulation issues (vascular claudication).
• Neurologist – for nerve-related limping, such as neurological disorders.
• Physical therapist – to provide exercises and rehabilitation techniques for better walking.

If the cause of the limping is unclear, it's best to start with a family doctor or pediatrician, who can refer you to the appropriate specialist.
