Clinical Presentation

Definition and Overview

A sprain of the ankle occurs when the ligaments that support the ankle joint are stretched or torn. The ICD-10 code S93.49 specifically pertains to sprains involving ligaments other than the primary ligaments typically affected in common ankle sprains, such as the anterior talofibular ligament (ATFL) or the calcaneofibular ligament (CFL) [1].

Signs and Symptoms

Patients with a sprain of other ligaments of the ankle may present with a variety of signs and symptoms, including:

• Pain: Localized pain around the ankle, which may vary in intensity depending on the severity of the sprain. Pain is often exacerbated by movement or weight-bearing activities.
• Swelling: Edema around the ankle joint is common, often resulting from inflammation and fluid accumulation in response to the injury.
• Bruising: Ecchymosis may develop around the ankle, indicating bleeding under the skin due to damaged blood vessels.
• Limited Range of Motion: Patients may experience difficulty in moving the ankle, particularly in dorsiflexion and plantarflexion, due to pain and swelling.
• Instability: A feeling of instability or weakness in the ankle may be reported, especially when attempting to bear weight or perform activities that require balance [2][3].

Patient Characteristics

Certain patient characteristics may influence the presentation and management of ankle sprains, including:

• Age: Younger individuals, particularly athletes, are more prone to ankle sprains due to higher levels of physical activity and participation in sports. However, older adults may also experience sprains due to falls or decreased proprioception.
• Activity Level: Patients engaged in high-impact sports or activities that involve jumping, running, or quick directional changes are at a higher risk for ankle sprains.
• Previous Injuries: A history of prior ankle sprains can predispose individuals to future injuries, as previous damage may lead to weakened ligaments and altered biomechanics.
• Footwear: The type of footwear worn can significantly impact the risk of ankle sprains. Inappropriate or unsupportive shoes may increase the likelihood of injury during physical activities [4].

Conclusion

In summary, the clinical presentation of a sprain of other ligaments of the ankle (ICD-10 code S93.49) is characterized by pain, swelling, bruising, limited range of motion, and potential instability of the ankle joint. Patient characteristics such as age, activity level, history of previous injuries, and footwear choices play a crucial role in both the incidence and management of these injuries. Understanding these factors is essential for effective diagnosis and treatment, ensuring that patients receive appropriate care tailored to their specific needs.
