ICD-10: M92.211

Osteochondrosis of the carpal lunate, commonly referred to as Kienböck's disease, is a condition that primarily affects the lunate bone in the wrist. This condition is characterized by the disruption of blood supply to the lunate, leading to avascular necrosis, which can result in pain, swelling, and limited mobility in the wrist. The ICD-10 code M92.211 specifically denotes this condition as it pertains to the right hand.

Clinical Description

Definition and Pathophysiology

Kienböck's disease is classified as a type of osteochondrosis, which refers to a group of disorders that affect the growth of bone in children and adolescents. In the case of the lunate, the condition typically arises due to repetitive trauma or microtrauma, which can compromise the blood supply to the bone. This lack of blood flow leads to the death of bone tissue, resulting in pain and dysfunction of the wrist joint[1].

Symptoms

Patients with Kienböck's disease may experience a variety of symptoms, including:
- Wrist Pain: Often localized to the area of the lunate, which may worsen with activity.
- Swelling: Inflammation around the wrist joint may be present.
- Decreased Range of Motion: Patients may find it difficult to move their wrist fully, particularly in flexion and extension.
- Tenderness: The area over the lunate may be sensitive to touch.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation and imaging studies. Key diagnostic tools include:
- X-rays: Initial imaging to assess the lunate and surrounding structures.
- MRI: More sensitive in detecting early changes in the lunate and assessing the extent of avascular necrosis[2].

Treatment Options

Management of Kienböck's disease can vary based on the severity of the condition and the age of the patient. Treatment options may include:
- Conservative Management: This may involve rest, immobilization with a splint or cast, and anti-inflammatory medications to reduce pain and swelling.
- Surgical Intervention: In more severe cases, procedures such as lunate decompression, bone grafting, or even wrist fusion may be considered to restore function and alleviate pain[3].
