ICD-10: M76.70

Peroneal tendinitis, classified under ICD-10 code M76.70, refers to inflammation of the peroneal tendons, which are located on the outer side of the lower leg. This condition can lead to pain and discomfort, particularly during activities that involve ankle movement or weight-bearing.

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 run down the lateral aspect of the leg, attaching to the foot. Their primary functions include:
- Stabilizing the ankle: They help maintain balance and stability during movement.
- Facilitating foot movement: They assist in eversion (turning the sole of the foot outward) and plantarflexion (pointing the toes).

Causes of Peroneal Tendinitis

Peroneal tendinitis can arise from various factors, including:
- Overuse: Repetitive activities, especially in sports like running or cycling, can lead to strain.
- Injury: Acute injuries or trauma to the ankle can cause inflammation.
- Biomechanical issues: Flat feet, high arches, or improper footwear can contribute to abnormal stress on the tendons.

Symptoms

Patients with peroneal tendinitis may experience:
- Pain: Typically located on the outer side of the ankle and foot, which may worsen with activity.
- Swelling: Inflammation around the tendon area.
- Stiffness: Reduced range of motion in the ankle.
- Tenderness: Pain upon palpation of the affected area.

Diagnosis

Diagnosis of peroneal tendinitis often involves:
- Clinical Examination: A healthcare provider will assess symptoms, perform a physical examination, and evaluate the range of motion.
- Imaging Studies: X-rays may be used to rule out fractures, while MRI or ultrasound can help visualize tendon inflammation and assess the extent of the injury.

Treatment Options

Management of peroneal tendinitis typically includes:
- Rest: Avoiding activities that exacerbate symptoms.
- Ice Therapy: Applying ice to reduce swelling and pain.
- Physical Therapy: Strengthening and stretching exercises to improve flexibility and support.
- Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to alleviate pain and inflammation.
