ICD-10: M85.062

Fibrous dysplasia is a bone disorder characterized by the replacement of normal bone with fibrous tissue, leading to structural weakness and deformity. The ICD-10 code M85.062 specifically refers to monostotic fibrous dysplasia located in the left lower leg. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Fibrous Dysplasia

Definition

Fibrous dysplasia is a benign skeletal disorder that occurs when normal bone is replaced by fibrous tissue, resulting in the formation of a mass that can weaken the bone structure. It can affect a single bone (monostotic) or multiple bones (polyostotic). The condition is often diagnosed in adolescents and young adults, although it can occur at any age.

Monostotic Fibrous Dysplasia

Monostotic fibrous dysplasia involves only one bone. In the case of M85.062, the affected area is the left lower leg, which typically includes the tibia and fibula. This localized form of the disease is more common than the polyostotic variant and often presents with fewer complications.

Symptoms

Patients with monostotic fibrous dysplasia may experience:
- Pain: This can range from mild to severe and may worsen with activity.
- Swelling: The affected area may appear swollen or deformed.
- Fractures: Weakened bone structure can lead to an increased risk of fractures, even with minimal trauma.
- Deformity: Over time, the affected bone may become misshapen, leading to functional impairment.

Diagnosis

Diagnosis of fibrous dysplasia typically involves:
- Imaging Studies: X-rays, CT scans, or MRIs are used to visualize the bone structure and assess the extent of the dysplasia. X-rays may show a characteristic "ground-glass" appearance of the affected bone.
- Biopsy: In some cases, a biopsy may be performed to confirm the diagnosis and rule out other conditions.

Treatment

Treatment options for monostotic fibrous dysplasia may include:
- Observation: In asymptomatic cases, monitoring the condition may be sufficient.
- Pain Management: Analgesics or anti-inflammatory medications can help manage pain.
- Surgery: In cases where there is significant deformity or fracture risk, surgical intervention may be necessary to stabilize the bone or correct deformities.

Prognosis

The prognosis for individuals with monostotic fibrous dysplasia is generally good, especially when the condition is diagnosed early and managed appropriately. Most patients can lead normal lives, although some may experience chronic pain or complications related to bone weakness.

Conclusion

ICD-10 code M85.062 identifies monostotic fibrous dysplasia of the left lower leg, a condition that can lead to pain, deformity, and an increased risk of fractures. Early diagnosis and appropriate management are crucial for optimizing outcomes and maintaining quality of life for affected individuals.

Clinical Presentation

Overview of Fibrous Dysplasia

Fibrous dysplasia can occur in a monostotic form, affecting a single bone, or in a polyostotic form, impacting multiple bones. The monostotic variant is more common and often presents in the long bones, including the femur, tibia, and fibula, as well as the skull and ribs. In the case of M85.062, the focus is on the left lower leg, which includes the tibia and fibula.

Signs and Symptoms

Patients with monostotic fibrous dysplasia of the left lower leg may exhibit a range of signs and symptoms, including:

• Pain: Patients often report localized pain in the affected area, which may be dull or aching and can worsen with activity or weight-bearing.
• Swelling: There may be noticeable swelling in the left lower leg due to the expansion of the fibrous tissue within the bone.
• Deformity: As the condition progresses, patients may develop deformities in the leg, such as bowing of the tibia or fibula, which can affect gait and mobility.
• Fractures: The weakened bone structure increases the risk of pathological fractures, even with minimal trauma.
• Limited Range of Motion: Patients may experience reduced mobility in the ankle and knee joints due to pain and structural changes.

Patient Characteristics

Fibrous dysplasia can affect individuals of any age, but certain characteristics are more commonly observed:

• Age of Onset: The condition often presents in childhood or adolescence, with many cases diagnosed before the age of 30. However, symptoms may not become apparent until later in life.
• Gender: There is no significant gender predilection, although some studies suggest a slight female predominance.
• Family History: While most cases are sporadic, a family history of fibrous dysplasia or related conditions may be noted in some patients, indicating a potential genetic component.

Diagnosis and Management

Diagnosis typically involves imaging studies such as X-rays, CT scans, or MRIs, which reveal characteristic findings such as ground-glass opacities and cortical thinning. A biopsy may be performed to confirm the diagnosis if necessary.

Management strategies may include:

• Pain Management: Analgesics and anti-inflammatory medications are often prescribed to alleviate pain.
• Surgical Intervention: In cases of significant deformity or recurrent fractures, surgical options such as curettage and bone grafting may be considered.
• Monitoring: Regular follow-up with imaging studies is essential to monitor the progression of the disease and assess for complications.
