ICD-10: M16.7

The ICD-10 code M16.7 refers to "Other unilateral secondary osteoarthritis of the hip." This condition is characterized by the degeneration of the hip joint due to factors other than primary osteoarthritis, which is typically age-related. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this diagnosis is crucial for effective management and treatment.

Clinical Presentation

Definition and Etiology

Unilateral secondary osteoarthritis of the hip occurs when the hip joint experiences degenerative changes due to underlying conditions or factors, such as previous injuries, inflammatory diseases, or metabolic disorders. Unlike primary osteoarthritis, which is often idiopathic and related to aging, secondary osteoarthritis can be traced back to specific causes, including:

• Previous trauma: Fractures or dislocations that affect the hip joint.
• Inflammatory conditions: Diseases such as rheumatoid arthritis or lupus.
• Metabolic disorders: Conditions like diabetes or obesity that can lead to joint stress.
• Congenital abnormalities: Hip dysplasia or other structural issues that predispose the joint to wear and tear.

Patient Characteristics

Patients with M16.7 typically exhibit certain demographic and clinical characteristics:

• Age: While secondary osteoarthritis can occur at any age, it is more common in middle-aged and older adults due to cumulative joint stress and previous injuries.
• Gender: There may be a slight male predominance, particularly in cases related to trauma or occupational stress.
• Comorbidities: Patients often have other health issues, such as obesity, diabetes, or previous joint diseases, which can exacerbate the condition.

Signs and Symptoms

Common Symptoms

Patients with unilateral secondary osteoarthritis of the hip may present with a variety of symptoms, including:

• Hip Pain: This is the most prominent symptom, often described as a deep, aching pain in the groin or outer thigh. Pain may worsen with activity and improve with rest.
• Stiffness: Patients often report stiffness in the hip joint, particularly after periods of inactivity, such as sitting or sleeping.
• Reduced Range of Motion: There may be a noticeable decrease in the ability to move the hip joint, affecting activities such as walking, climbing stairs, or putting on shoes.
• Swelling: In some cases, mild swelling around the hip joint may be observed, particularly during flare-ups.

Physical Examination Findings

During a clinical examination, healthcare providers may note:

• Tenderness: Palpation of the hip joint may elicit tenderness, particularly over the anterior and lateral aspects.
