Clinical Presentation

Definition and Overview

Algoneurodystrophy is a disorder that involves a malfunction of the nervous system, leading to severe pain, swelling, and changes in the skin and bones of the affected area. It often occurs after trauma, surgery, or immobilization of a limb, particularly in the extremities.

Common Symptoms

Patients with algoneurodystrophy may experience a variety of symptoms, which can vary in intensity and duration. Key symptoms include:

• Severe Pain: The hallmark of algoneurodystrophy is intense, burning pain that is disproportionate to the initial injury. This pain can be constant or intermittent and may worsen with movement or touch[1].
• Swelling: The affected area, such as the right ankle and foot, may exhibit significant swelling due to inflammation and fluid accumulation[1].
• Changes in Skin Color and Temperature: The skin over the affected area may become discolored, appearing red, blue, or pale. Additionally, temperature changes can occur, with the affected limb feeling warmer or cooler than the surrounding areas[1][2].
• Altered Sensation: Patients often report hypersensitivity to touch (allodynia) or changes in sensation, such as tingling or numbness[2].
• Motor Dysfunction: There may be a decrease in range of motion, weakness, or difficulty in moving the affected limb, which can lead to functional impairment[1][3].

Signs

During a clinical examination, healthcare providers may observe several signs indicative of algoneurodystrophy:

• Edema: Noticeable swelling in the right ankle and foot, which may be pitting or non-pitting[1].
• Skin Changes: The skin may appear shiny, thin, or atrophic, and hair growth patterns may change[2].
• Temperature Variations: The affected limb may exhibit temperature differences compared to the contralateral limb, often being warmer or cooler[1][3].
• Bone Changes: In advanced cases, imaging studies may reveal bone demineralization or osteopenia in the affected area[2].

Patient Characteristics

Certain patient characteristics may predispose individuals to develop algoneurodystrophy:

• Age: While algoneurodystrophy can occur at any age, it is more commonly diagnosed in adults, particularly those aged 40 to 60 years[2].
• Gender: There is a higher prevalence in females compared to males, with some studies suggesting a ratio of approximately 3:1[3].
• Previous Injuries: A history of trauma, surgery, or immobilization of the affected limb is often noted, as these events can trigger the onset of symptoms[1][2].
• Psychological Factors: Patients with a history of anxiety, depression, or other psychological conditions may be at increased risk for developing algoneurodystrophy following an injury[3].
