ICD-10: S93.412

The clinical presentation of a sprain of the calcaneofibular ligament (CFL) of the left ankle, classified under ICD-10 code S93.412, involves a range of signs and symptoms that can help in diagnosing the condition. Understanding these characteristics is crucial for effective management and treatment.

Clinical Presentation

Mechanism of Injury

A sprain of the calcaneofibular ligament typically occurs due to an inversion injury of the ankle, where the foot rolls inward excessively. This can happen during activities such as running, jumping, or walking on uneven surfaces. The CFL is one of the key ligaments that provide stability to the ankle joint, and its injury can lead to significant functional impairment[1][2].

Signs and Symptoms

Patients with a CFL sprain may exhibit the following signs and symptoms:

• Pain: Localized pain on the outer side of the ankle, which may worsen with movement or weight-bearing activities. The intensity of pain can vary depending on the severity of the sprain[3].
• Swelling: Swelling around the ankle joint is common, often appearing within a few hours after the injury. This swelling can extend to the surrounding tissues[4].
• Bruising: Ecchymosis or bruising may develop around the ankle, indicating bleeding under the skin due to ligament damage[5].
• Limited Range of Motion: Patients may experience difficulty in moving the ankle, particularly in dorsiflexion and inversion, due to pain and swelling[6].
• Instability: A feeling of instability or "giving way" in the ankle may be reported, especially during activities that require lateral movement[7].

Patient Characteristics

Certain patient characteristics can influence the presentation and management of a CFL sprain:

• Age: Younger individuals, particularly athletes, are more prone to ankle sprains due to higher levels of physical activity. However, older adults may also experience sprains due to falls or decreased proprioception[8].
• Activity Level: Active individuals, especially those involved in sports that require quick changes in direction, are at a higher risk for CFL injuries[9].
• Previous Injuries: A history of previous ankle sprains can predispose patients to recurrent injuries, as the ligaments may be weakened or less stable[10].
• Foot Structure: Individuals with certain foot types, such as flat feet or high arches, may have altered biomechanics that increase the risk of ankle sprains[11].

Conclusion

In summary, a sprain of the calcaneofibular ligament of the left ankle (ICD-10 code S93.412) presents with characteristic signs and symptoms, including pain, swelling, bruising, limited range of motion, and instability. Patient characteristics such as age, activity level, history of previous injuries, and foot structure can significantly influence the clinical presentation and management of this condition. Proper assessment and treatment are essential to ensure effective recovery and prevent future injuries.
