ICD-10: M93.259

Osteochondritis dissecans (OCD) is a joint condition in which a variable amount of bone and cartilage becomes detached from the surrounding tissue due to a lack of blood flow. The ICD-10 code M93.259 specifically refers to osteochondritis dissecans of the hip when the specific site is not further specified. Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for diagnosis and management.

Clinical Presentation

Overview of Osteochondritis Dissecans

Osteochondritis dissecans typically occurs in the knee but can also affect other joints, including the hip. It is characterized by the following:

• Age Group: Most commonly affects adolescents and young adults, particularly those involved in sports that place stress on the joints.
• Activity Level: Often seen in individuals who engage in high-impact activities or sports, such as basketball, football, or gymnastics.

Signs and Symptoms

Patients with osteochondritis dissecans of the hip may present with a variety of signs and symptoms, including:

• Hip Pain: Patients often report localized pain in the hip joint, which may worsen with activity and improve with rest. The pain can be deep and may radiate to the groin or thigh.
• Joint Stiffness: Stiffness in the hip joint, particularly after periods of inactivity or in the morning, is common.
• Limited Range of Motion: Patients may experience a reduced range of motion in the hip, making it difficult to perform activities such as walking, running, or climbing stairs.
• Swelling: There may be mild swelling around the hip joint, although this is less common than in other joints like the knee.
• Catching or Locking Sensation: Some patients may describe a sensation of catching or locking in the hip joint, which can occur if a fragment of bone or cartilage becomes loose.

Patient Characteristics

Certain characteristics may predispose individuals to develop osteochondritis dissecans of the hip:

• Demographics: More prevalent in males than females, particularly in the adolescent age group.
• Sports Participation: Higher incidence in athletes, especially those involved in sports that require repetitive hip motion or high-impact activities.

Osteochondritis dissecans (OCD) is a joint condition in which a variable amount of bone and cartilage becomes detached from the surrounding tissue due to a lack of blood flow. This condition can lead to pain, swelling, and joint dysfunction, particularly in weight-bearing joints such as the knee and hip. The ICD-10 code M93.259 specifically refers to osteochondritis dissecans of the hip that is unspecified, meaning that the exact location or severity of the condition within the hip joint is not detailed.

Clinical Description of Osteochondritis Dissecans

Pathophysiology

Osteochondritis dissecans typically occurs in adolescents and young adults, often as a result of repetitive trauma or stress to the joint. The condition is characterized by the following:

• Ischemia: Reduced blood supply to the bone leads to necrosis of the subchondral bone, which can result in the formation of a loose fragment of bone and cartilage.
• Detachment: The affected area may become unstable, leading to the detachment of the cartilage and underlying bone, which can cause joint pain and mechanical symptoms.

Symptoms

Patients with OCD of the hip may experience:

• Pain: Often localized to the hip joint, which may worsen with activity or weight-bearing.
• Swelling: Inflammation around the joint may lead to visible swelling.
• Limited Range of Motion: Patients may find it difficult to move the hip joint fully due to pain or mechanical blockage.
• Joint Locking or Catching: Loose fragments can cause the joint to lock or catch during movement.

Diagnosis

Diagnosis of osteochondritis dissecans typically involves:

• Clinical Evaluation: A thorough history and physical examination to assess symptoms and joint function.
• Imaging Studies: X-rays are commonly used to identify changes in the bone structure, while MRI can provide detailed images of the cartilage and any loose bodies within the joint.

Treatment Options

Management of OCD in the hip can vary based on the severity of the condition and the patient's age. Treatment options may include:

• Conservative Management: Rest, activity modification, and physical therapy to strengthen surrounding muscles and improve joint stability.
• Surgical Intervention: In cases where conservative treatment fails or if there is significant detachment, surgical options may include arthroscopy to remove loose bodies or repair the damaged cartilage.
