The ICD-10 code M89.44 specifically refers to "Other hypertrophic osteoarthropathy, hand," indicating a form of HOA that affects the bones and joints of the hand.

Clinical Description

Definition

Hypertrophic osteoarthropathy is primarily characterized by the following features:
- Periosteal Bone Formation: This involves the abnormal growth of bone tissue along the periosteum, which is the outer fibrous layer covering the bones.
- Joint Changes: Patients may experience joint pain, swelling, and stiffness, particularly in the affected areas.

Etiology

The condition can be secondary to various underlying health issues, including:
- Pulmonary Diseases: Conditions such as lung cancer, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis are commonly associated with HOA.
- Cardiovascular Disorders: Congenital heart disease and other heart conditions can also lead to the development of HOA.
- Other Conditions: Infections, inflammatory diseases, and certain metabolic disorders may contribute to the onset of hypertrophic osteoarthropathy.

Symptoms

Patients with M89.44 may present with:
- Pain and Discomfort: Often localized to the hands, with possible radiating pain to the wrists and forearms.
