M77.3 Calcaneal spur

Name of the Condition

• Calcaneal spur

Summary

Calcaneal spur refers to a bony outgrowth that forms on the heel bone (calcaneus). This condition can cause discomfort, especially when walking or standing, as the spur may press against soft tissues.

Causes

Calcaneal spur typically develops due to chronic inflammation of the plantar fascia, the thick band of tissue running along the bottom of the foot. Overuse or excessive stress on the heel, such as from repetitive activities or prolonged standing, can contribute to its formation.

Risk Factors

• Age (more common in individuals over 40)
• Obesity or excessive weight
• High-impact activities such as running or jumping
• Foot structure issues, such as flat feet or high arches
• Wearing poorly fitting or unsupportive footwear

Symptoms

• Heel pain, often worse in the morning or after prolonged sitting
• Tenderness at the base of the heel
• Swelling and inflammation in the heel area

Diagnosis

Diagnosis involves a physical examination of the foot to assess pain and tenderness. Imaging tests like X-rays may be used to visualize the spur and rule out other conditions. Assessment of gait and foot structure may also be performed.

Treatment Options

• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation
• Physical therapy to strengthen and stretch the foot muscles
• Orthotic devices and supportive footwear to relieve pressure
• Corticosteroid injections for severe pain
• Surgery in extreme cases to remove the spur

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment. Most individuals experience relief from symptoms with conservative measures. Follow-up may involve monitoring pain levels and adjusting treatment as needed.

Complications

• Chronic heel pain that interferes with daily activities
• Difficulty walking or standing for prolonged periods
• Potential development of plantar fasciitis or Achilles tendonitis

Lifestyle & Prevention

• Maintain a healthy weight to reduce stress on the heels
• Wear supportive footwear with good arch support
• Avoid high-impact activities that strain the heels
• Stretch the plantar fascia and Achilles tendon regularly

When to Seek Professional Help

Seek medical attention if heel pain persists despite home care, worsens over time, or is accompanied by swelling, redness, or difficulty bearing weight.

Tips for Medical Coders

Document the presence of a calcaneal spur and any associated symptoms or treatments. Ensure the code M77.3 is used when the condition is specifically identified as a calcaneal spur without additional site or laterality specifications.
