Clinical Description of Subacute Osteomyelitis

Definition

Subacute osteomyelitis is characterized by a gradual onset of symptoms, typically occurring over a period of weeks to months. Unlike acute osteomyelitis, which presents suddenly and is often more severe, subacute osteomyelitis may have milder symptoms and can sometimes be mistaken for other conditions.

Symptoms

Patients with subacute osteomyelitis may experience:
- Localized pain in the affected area (in this case, the left humerus).
- Swelling and tenderness over the bone.
- Fever and general malaise, although these symptoms may be less pronounced than in acute cases.
- Limited range of motion in the shoulder or arm due to pain and swelling.

Causes

The condition can arise from:
- Hematogenous spread: Infection spreading through the bloodstream from another site in the body.
- Contiguous spread: Infection spreading from nearby tissues, often due to trauma or surgery.
- Chronic conditions: Such as diabetes or peripheral vascular disease, which can predispose individuals to infections.

Diagnosis

Diagnosis typically involves:
- Clinical evaluation: Assessing symptoms and medical history.
