S93.411 Sprain of calcaneofibular ligament of right ankle

Name of the Condition

• Common Name: Ankle sprain
• Medical Term: Sprain of calcaneofibular ligament of right ankle

Summary

A sprain of the calcaneofibular ligament of the right ankle is an injury where the ligament connecting the calcaneus (heel bone) to the fibula (lower leg bone) is stretched, torn, or otherwise damaged. This typically results from a sudden twist or roll of the foot, leading to pain and instability in the right ankle.

Causes

This injury often occurs due to activities that involve sudden changes in direction, such as sports, or from uneven surfaces that cause the ankle to turn awkwardly. Direct trauma to the outer ankle may also contribute.

Risk Factors

• Participation in sports, especially those involving running, jumping, or sharp movements
• Walking or running on uneven surfaces
• Previous ankle injuries, which can weaken ligaments
• Wearing inappropriate or unsupportive footwear

Symptoms

• Swelling and bruising around the outer right ankle
• Pain or tenderness when touching or moving the right ankle
• Limited range of motion in the right ankle
• Instability and difficulty bearing weight on the right foot

Diagnosis

Physical examination to assess pain, swelling, range of motion, and stability of the right ankle. Imaging tests such as X-rays to rule out fractures, and MRI to assess ligament damage.

Treatment Options

• R.I.C.E. method: Rest, Ice, Compression, and Elevation to reduce swelling and pain
• Physical therapy: Exercises to restore strength, flexibility, and balance
• Medication: NSAIDs to alleviate pain and inflammation

Prognosis and Follow-Up

Most sprains heal within a few weeks with proper care. Follow-up may involve monitoring for persistent pain or instability, and physical therapy to prevent recurrence.

Complications

• Chronic ankle instability
• Persistent pain or swelling
• Increased risk of future sprains

Lifestyle & Prevention

• Wear supportive footwear during physical activities
• Use ankle braces or tape for high-risk activities
• Improve balance and strength through targeted exercises
• Avoid uneven surfaces when possible

When to Seek Professional Help

Seek medical attention if you experience severe pain, inability to bear weight, visible deformity, or if symptoms do not improve with home care.

Tips for Medical Coders

Document the specific ligament (calcaneofibular) and laterality (right) to ensure accurate coding. Include details about the mechanism of injury and clinical findings to support the diagnosis.
