ICD-10: M76.71

Peroneal tendinitis, specifically coded as ICD-10-CM M76.71, refers to the inflammation of the peroneal tendons located on the outer side of the ankle and foot. This condition is characterized by pain and discomfort in the right leg, particularly around the lateral aspect of the ankle, where the peroneal tendons run.

Clinical Description

Anatomy and Function

The peroneal tendons consist of two main tendons: the peroneus longus and the peroneus brevis. These tendons originate from the fibula and travel down the lateral side of the leg, passing behind the lateral malleolus (the bony prominence on the outside of the ankle). Their primary functions include:
- Stabilizing the ankle: They help maintain balance and stability during activities such as walking, running, and jumping.
- Eversion of the foot: They assist in turning the sole of the foot outward.

Symptoms

Patients with peroneal tendinitis typically present with the following symptoms:
- Localized pain: Pain is often felt on the outer side of the ankle and may radiate up the leg.
- Swelling: There may be visible swelling around the area of the tendons.
- Tenderness: The affected area is usually tender to touch.
- Stiffness: Patients may experience stiffness, particularly after periods of inactivity.
- Difficulty with movement: Activities that involve ankle movement, especially eversion, may exacerbate the pain.

Causes

Peroneal tendinitis can arise from various factors, including:
- Overuse: Repetitive activities, particularly in athletes or individuals engaged in sports that involve lateral movements, can lead to inflammation.
- Injury: Acute injuries, such as ankle sprains, can damage the tendons.
- Biomechanical issues: Flat feet, high arches, or improper footwear can contribute to abnormal stress on the tendons.

Diagnosis

Diagnosis of peroneal tendinitis typically involves:
- Clinical evaluation: A thorough physical examination to assess pain, swelling, and range of motion.
- Imaging studies: X-rays may be used to rule out fractures, while MRI or ultrasound can provide detailed images of the tendons and surrounding tissues to confirm inflammation.

Treatment

Management of peroneal tendinitis often includes:
- Rest: Reducing activities that exacerbate symptoms.
- Ice therapy: Applying ice to the affected area to reduce swelling and pain.
- Physical therapy: Strengthening and stretching exercises to improve flexibility and support the ankle.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to alleviate pain and inflammation.
- Injections: In some cases, corticosteroid injections may be considered to reduce inflammation.

Conclusion
