ICD-10: M86.64

ICD-10 code M86.64 refers specifically to "Other chronic osteomyelitis, hand." This classification falls under the broader category of osteomyelitis, which is an infection of the bone that can be caused by various pathogens, including bacteria and fungi. Chronic osteomyelitis is characterized by a prolonged infection that can lead to bone necrosis and other complications.

Clinical Description

Definition

Chronic osteomyelitis is defined as a persistent infection of the bone that lasts for more than one month. It can occur following an acute infection that was inadequately treated or can arise from a contiguous focus of infection, such as from a nearby soft tissue infection or post-surgical complications. In the case of M86.64, the infection specifically affects the bones of the hand.

Etiology

The etiology of chronic osteomyelitis can vary, but common causes include:
- Bacterial Infections: Staphylococcus aureus is a frequent pathogen, particularly in cases following trauma or surgery.
- Fungal Infections: Less commonly, fungi can cause osteomyelitis, especially in immunocompromised patients.
- Contiguous Infections: Infections from adjacent tissues, such as skin or soft tissue infections, can spread to the bone.

Symptoms

Patients with chronic osteomyelitis of the hand may present with:
- Localized Pain: Persistent pain in the affected area, which may worsen with movement.
- Swelling and Redness: Inflammation around the site of infection.
- Fever: Although less common in chronic cases, systemic symptoms may occur.
- Drainage: Pus or other discharge may be present, especially if there is an open wound or sinus tract.

Diagnosis

Diagnosis typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and identify potential sources of infection.
- Imaging Studies: X-rays, MRI, or CT scans can help visualize bone changes, such as necrosis or abscess formation.
- Microbiological Testing: Cultures from bone biopsies or drainage can identify the causative organism.

Treatment

Management of chronic osteomyelitis often includes:
- Antibiotic Therapy: Prolonged courses of antibiotics tailored to the identified pathogen.
