ICD-10: M12.271

Villonodular synovitis (pigmented), classified under ICD-10 code M12.271, is a rare condition characterized by the proliferation of synovial tissue, which can lead to joint swelling and pain. This specific code pertains to the occurrence of this condition in the right ankle and foot.

Clinical Description

Definition

Villonodular synovitis (VNS) is a benign but locally aggressive condition that affects the synovial membrane of joints, tendons, and bursae. The "pigmented" variant refers to the presence of hemosiderin deposits, which are indicative of previous bleeding within the joint space. This condition is often associated with a history of trauma or repetitive stress to the affected area, although the exact cause remains unclear.

Symptoms

Patients with pigmented villonodular synovitis typically present with the following symptoms:
- Joint Swelling: The affected ankle may appear swollen due to synovial proliferation.
- Pain: Patients often report pain that can be exacerbated by movement or weight-bearing activities.
- Limited Range of Motion: The swelling and pain can lead to decreased mobility in the ankle joint.
- Joint Stiffness: Stiffness may occur, particularly after periods of inactivity.

Diagnosis

Diagnosis of M12.271 involves a combination of clinical evaluation and imaging studies:
- Physical Examination: A thorough examination by a healthcare provider to assess swelling, tenderness, and range of motion.
- Imaging: MRI is the preferred imaging modality, as it can reveal the characteristic features of VNS, including joint effusion and synovial thickening. X-rays may show bone changes or joint effusion but are less definitive.
- Histological Examination: In some cases, a biopsy may be performed to confirm the diagnosis, revealing the characteristic histological features of pigmented villonodular synovitis.

Treatment

Management of villonodular synovitis typically includes:
- Conservative Treatment: Initial management may involve rest, ice, compression, and elevation (RICE), along with non-steroidal anti-inflammatory drugs (NSAIDs) for pain relief.
- Corticosteroid Injections: Intra-articular corticosteroid injections may help reduce inflammation and alleviate symptoms.
- Surgical Intervention: If conservative measures fail, surgical excision of the affected synovial tissue may be necessary. This is often the definitive treatment to prevent recurrence.

Conclusion

ICD-10 code M12.271 specifically identifies pigmented villonodular synovitis affecting the right ankle and foot. Understanding the clinical presentation, diagnostic approach, and treatment options is crucial for effective management of this condition. Early diagnosis and appropriate intervention can significantly improve patient outcomes and quality of life.
