Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue due to a lack of blood supply. The ICD-10 code M87.276 specifically refers to osteonecrosis that occurs in the foot as a result of previous trauma, but without further specification regarding the exact location within the foot.

Clinical Description of M87.276

Definition and Pathophysiology

Osteonecrosis due to previous trauma involves the disruption of blood flow to a specific area of bone, leading to bone cell death. This condition can arise after a fracture, dislocation, or other significant injuries that compromise the vascular supply to the bone. The foot, being a complex structure with multiple bones, can be affected in various ways, leading to localized pain, swelling, and potential joint dysfunction.

Symptoms

Patients with osteonecrosis of the foot may experience:
- Pain: Often localized to the affected area, which may worsen with weight-bearing activities.
- Swelling: Inflammation around the affected joint or bone.
- Limited Range of Motion: Difficulty in moving the foot or toes due to pain or mechanical instability.
- Joint Stiffness: Particularly after periods of inactivity.

Diagnosis

Diagnosis of osteonecrosis typically involves:
- Clinical Evaluation: A thorough history and physical examination to assess symptoms and previous trauma.
- Imaging Studies: X-rays may initially show changes in bone structure, while MRI is more sensitive in detecting early osteonecrosis and assessing the extent of the condition.
