ICD-10: S93.41

The ICD-10 code S93.41 specifically refers to a sprain of the calcaneofibular ligament, which is a common injury associated with ankle sprains. This ligament plays a crucial role in stabilizing the ankle joint, particularly during activities that involve lateral movements or changes in direction.

Clinical Description

Anatomy and Function

The calcaneofibular ligament is one of the key ligaments located on the lateral side of the ankle. It connects the fibula (the smaller bone of the lower leg) to the calcaneus (the heel bone). Its primary function is to provide stability to the ankle, especially during inversion movements, where the foot rolls inward. Injury to this ligament often occurs in conjunction with other ankle ligaments, particularly during sports or activities that involve jumping, running, or sudden changes in direction.

Mechanism of Injury

A sprain of the calcaneofibular ligament typically occurs due to:
- Inversion injuries: When the foot rolls inward excessively, placing stress on the lateral ligaments.
- Trauma: Direct impact or twisting motions can also lead to ligament sprains.
- Overuse: Repetitive stress on the ankle can weaken the ligament over time, making it more susceptible to injury.

Symptoms

Patients with a sprain of the calcaneofibular ligament may experience:
- Pain: Localized pain on the outer side of the ankle, which may worsen with movement.
- Swelling: Inflammation around the ankle joint, often visible within hours of the injury.
- Bruising: Discoloration may appear due to bleeding under the skin.
- Instability: A feeling of weakness or instability in the ankle, particularly when bearing weight.

Diagnosis

Diagnosis of a calcaneofibular ligament sprain typically involves:
- Physical Examination: Assessment of pain, swelling, and range of motion.
- Imaging Studies: X-rays may be performed to rule out fractures, while MRI can provide detailed images of soft tissue injuries, including ligament damage.

Treatment

The management of a sprain of the calcaneofibular ligament generally includes:
- Rest: Avoiding activities that exacerbate the injury.
- Ice: Applying ice packs to reduce swelling and pain.
- Compression: Using elastic bandages to minimize swelling.
- Elevation: Keeping the ankle elevated to decrease swelling.
- Rehabilitation: Physical therapy may be recommended to restore strength and flexibility.
- Surgery: In severe cases, surgical intervention may be necessary to repair the ligament.

Prognosis

The prognosis for a sprain of the calcaneofibular ligament is generally favorable, with most patients recovering fully with appropriate treatment. However, the recovery time can vary based on the severity of the sprain, ranging from a few weeks for mild sprains to several months for more severe injuries.

In summary, the ICD-10 code S93.41 encapsulates the clinical aspects of a sprain of the calcaneofibular ligament, highlighting its significance in ankle stability and the common mechanisms of injury associated with this condition. Proper diagnosis and treatment are essential for optimal recovery and prevention of future injuries.

The clinical presentation of a sprain of the calcaneofibular ligament, classified under ICD-10 code S93.41, involves a range of signs and symptoms that can significantly impact a patient's mobility and overall function. Understanding these aspects is crucial for accurate diagnosis and effective management.

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 is common in activities that involve jumping, running, or sudden changes in direction, such as in sports like basketball or soccer[1].

Signs and Symptoms

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