Things worth knowing about "Ulcus cruris"

Ulcus cruris is a chronic non-healing wound on the lower leg, most commonly caused by venous or arterial circulatory disorders. It primarily affects older adults and requires targeted medical care.

What is Ulcus Cruris?

Ulcus cruris (also known as a leg ulcer or open leg wound) is a chronic, poorly healing wound located on the lower leg or ankle. It represents a deep tissue defect of the skin and subcutaneous tissue, typically caused by impaired circulation, lymphatic drainage disorders, or other underlying systemic diseases. Leg ulcers are among the most common chronic wounds worldwide and disproportionately affect the elderly population.

Causes

Ulcus cruris is classified into several types based on its underlying cause:

Venous leg ulcer (Ulcus cruris venosum): The most common form, accounting for approximately 60–80% of all cases. It results from chronic venous insufficiency (CVI), where impaired venous return from the leg leads to elevated venous pressure, tissue changes, and ulceration.
Arterial leg ulcer (Ulcus cruris arteriosum): Caused by peripheral arterial disease (PAD), in which narrowed arteries reduce oxygen supply to the tissue. This form is typically more painful.
Mixed-type ulcer (Ulcus cruris mixtum): A combination of venous and arterial insufficiency.
Other causes: Diabetes mellitus (diabetic ulcer), vasculitis, infections, tumors, or lymphedema.

Symptoms

Symptoms may vary depending on the type of ulcer but commonly include:

Open, non-healing wound on the lower leg or ankle
Irregular wound edges with a fibrinous or necrotic wound bed
Pain (particularly pronounced in arterial ulcers; venous ulcers are often less painful)
Swelling of the lower leg
Skin discoloration and hardening of the surrounding tissue (lipodermatosclerosis)
Itching and weeping wound exudate
Unpleasant odor in cases of infection

Diagnosis

Diagnosis is established through a thorough clinical assessment combined with targeted diagnostic procedures:

Medical history and physical examination: Assessment of wound characteristics, surrounding skin, and circulatory status.
Doppler ultrasound: Measurement of the ankle-brachial index (ABI) to evaluate arterial blood flow.
Duplex sonography: Imaging of veins and arteries to identify the underlying cause.
Wound swab: To detect bacterial colonization or infection and identify pathogens.
Biopsy: To rule out malignant transformation in atypical or non-healing wounds.
Laboratory tests: Blood glucose, inflammatory markers, and coagulation parameters.

Treatment

Treatment of ulcus cruris is cause-oriented and follows a multi-modal approach:

Treatment of the Underlying Condition

Addressing the root cause is essential -- whether this involves managing chronic venous insufficiency, peripheral arterial disease, or diabetes mellitus.

Local Wound Care

Wound cleansing and debridement (removal of necrotic or non-viable tissue)
Moist wound healing using modern wound dressings (e.g., hydrocolloids, alginates, foam dressings)
Antibiotic therapy in confirmed wound infections

Compression Therapy

For venous leg ulcers, compression therapy using compression bandages or stockings is the cornerstone of treatment. It reduces venous pressure and significantly promotes wound healing.

Additional Therapeutic Options

Vascular surgery or interventional procedures for arterial involvement
Skin grafting for large or treatment-resistant ulcers
Physiotherapy and exercise to activate the muscle pump
Adequate pain management

Prognosis and Prevention

Without consistent treatment, ulcus cruris can persist for months to years and lead to serious complications such as deep tissue infections or sepsis. With appropriate therapy, most wounds will heal, but the recurrence rate remains high. Preventive measures include regular physical activity, consistent use of compression stockings, careful skin care, and optimal management of underlying conditions such as diabetes or hypertension.
