Clinical Presentation

Definition and Overview

Algoneurodystrophy is characterized by severe pain, swelling, and changes in the skin and bone of the affected area. It often follows an injury, but the pain experienced is disproportionate to the initial trauma. The condition can be classified into two types: CRPS Type I (formerly known as reflex sympathetic dystrophy) and CRPS Type II (causalgia), with Type I being more common and not involving identifiable nerve injury.

Onset and Progression

The onset of algoneurodystrophy can occur within days to weeks following an injury. The condition may progress through several stages, each with distinct features:

1. Acute Stage: This initial phase may last for several weeks and is marked by intense pain, swelling, and changes in skin temperature and color.
2. Dystrophic Stage: Lasting from several months to a year, this stage may involve continued pain, stiffness, and atrophy of the affected limb.
3. Atrophic Stage: This chronic phase can lead to irreversible changes, including muscle atrophy and joint contractures.

Signs and Symptoms

Pain

• Severe Pain: Patients often report a burning or throbbing pain that is out of proportion to the initial injury. The pain may be constant or intermittent and can be exacerbated by movement or touch.

Swelling and Changes in Skin

• Edema: Swelling in the affected ankle and foot is common.
• Skin Changes: The skin may exhibit color changes (red, blue, or pale), temperature fluctuations (hot or cold), and may become shiny or thin.

Motor and Sensory Changes

• Reduced Range of Motion: Patients may experience stiffness and difficulty moving the ankle and foot.
