ICD-10: M87.352

Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. The ICD-10 code M87.352 specifically refers to "Other secondary osteonecrosis, left femur," indicating that the osteonecrosis is not primary but rather secondary to other underlying conditions or factors. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for effective diagnosis and management.

Clinical Presentation

Overview of Osteonecrosis

Osteonecrosis can occur in various bones, but the femur is one of the most commonly affected sites. The left femur's involvement suggests that the symptoms and clinical findings will be localized to that area. Secondary osteonecrosis can arise from various causes, including trauma, corticosteroid use, alcohol abuse, and certain medical conditions such as systemic lupus erythematosus or sickle cell disease[1][2].

Signs and Symptoms

Patients with secondary osteonecrosis of the left femur may present with a range of signs and symptoms, including:

• Pain: The most common symptom is pain in the hip or groin area, which may worsen with weight-bearing activities and improve with rest. The pain can be sharp or dull and may radiate to the knee[3].
• Limited Range of Motion: Patients may experience stiffness and a reduced range of motion in the hip joint, making it difficult to perform daily activities such as walking or climbing stairs[4].
• Swelling and Tenderness: There may be localized swelling and tenderness over the affected area, particularly around the hip joint[5].
• Limping: Due to pain and discomfort, patients may develop a limp or altered gait[6].

Progression of Symptoms

As the condition progresses, symptoms may worsen, leading to increased pain and functional impairment. In advanced cases, patients may experience significant joint damage, leading to osteoarthritis and chronic pain[7].

Patient Characteristics

Demographics

Osteonecrosis can affect individuals of various ages, but certain demographic factors may influence its prevalence:

• Age: It is more common in individuals aged 30 to 60 years, although it can occur in younger patients, particularly those with risk factors[8].
• Gender: Males are generally more affected than females, particularly in cases related to alcohol use or trauma[9].

Risk Factors

Several risk factors are associated with secondary osteonecrosis, including:

• Corticosteroid Use: Long-term use of corticosteroids is a well-known risk factor for developing osteonecrosis, as it can impair blood flow to the bones[10].
• Alcohol Abuse: Excessive alcohol consumption can lead to fatty deposits in blood vessels, reducing blood supply to the bone[11].
• Medical Conditions: Conditions such as lupus, sickle cell disease, and certain metabolic disorders can predispose individuals to osteonecrosis[12].
• Trauma: Previous fractures or injuries to the hip can disrupt blood flow and lead to osteonecrosis[13].

Comorbidities

Patients with secondary osteonecrosis may also present with comorbid conditions that can complicate management, such as obesity, diabetes, or cardiovascular diseases, which can further impact bone health and healing[14].

Conclusion

Secondary osteonecrosis of the left femur, coded as M87.352, presents with characteristic symptoms such as hip pain, limited range of motion, and potential swelling. Understanding the clinical presentation and patient characteristics is essential for timely diagnosis and intervention. Management may involve addressing underlying risk factors, pain management, and possibly surgical interventions in advanced cases. Early recognition and treatment can significantly improve outcomes for affected individuals.
