Leg ulcers affect 1 to 2 people in every 100 in the UK, creating persistent pain, immobility and risk of infection. This comprehensive guide delivers evidence-based strategies for effective treatment of leg ulcers by exploring underlying causes, core therapies and emerging innovations. You will discover how identifying ulcer types—venous ulcers, arterial ulcers and diabetic leg ulcers—guides tailored care, why compression therapy remains the gold standard for venous wounds, and which dressings best support healing. Advanced options such as surgery, hyperbaric oxygen therapy and negative pressure wound therapy are unpacked, along with practical pain relief, antibiotic use and self-care practices to prevent infection. Finally, learn how lifestyle modifications, ongoing specialist referrals and UK-specific guidelines from the NHS and NICE foster long-term recovery and minimise recurrence. By following these structured recommendations, patients and clinicians can collaborate to promote faster healing, reduce complications and restore quality of life.
A leg ulcer is a break in the skin on the lower leg that fails to heal within two weeks, usually driven by underlying vascular or systemic conditions. Identifying whether an ulcer arises from venous insufficiency, arterial disease or diabetes influences both prognosis and treatment pathways. Venous leg ulcers develop when weakened vein valves allow blood pooling, causing pressure-related skin breakdown. Arterial leg ulcers result from impaired arterial flow and oxygen delivery, leading to tissue starvation and ulceration. Diabetic leg ulcers stem from neuropathy, high blood sugar and microvascular damage, carrying heightened infection risk. Recognising these mechanisms enhances targeted interventions and improves healing outcomes.
A venous leg ulcer develops when chronic venous insufficiency elevates pressure in the calf veins, causing fluid leakage, inflammation and skin breakdown. This mechanism impairs oxygen exchange and nutrient delivery to tissues, resulting in shallow, exudative wounds often located above the ankle. Effective compression therapy addresses the pooling by improving venous return and promoting ulcer closure.
Arterial leg ulcers occur when peripheral artery disease restricts blood flow, depriving tissue of oxygen and essential nutrients. These ulcers present as deep, punched-out lesions with well-defined edges and minimal exudate. Revascularisation or bypass procedures restore perfusion to support healing.
Diabetic leg ulcers arise from peripheral neuropathy, microangiopathy and poor glycaemic control. Numbness prevents early detection, while reduced microcirculation and immune compromise raise the risk of severe infection. Offloading pressure and tight blood sugar management are crucial to prevent ulcer formation and promote closure.
Exposure to venous hypertension, peripheral arterial disease, diabetes and immobility significantly raises ulcer risk. Additional factors include obesity, older age, deep vein thrombosis history and smoking-related vascular damage. Addressing these contributors supports preventive care and reduces new ulcer onset.

Understanding ulcer characteristics clarifies why targeted interventions like compression therapy become essential.
Compression therapy applies graduated pressure to the lower limb, reducing venous hypertension and improving microcirculation. By counteracting fluid accumulation and promoting venous return, bandaging, hosiery and wraps accelerate ulcer healing. This treatment also supports calf muscle pump efficiency, decreasing oedema and enhancing tissue oxygenation for faster repair.
Three principal compression systems include multi-layer bandages, compression stockings and adjustable wraps. Multi-layer bandages deliver strong, sustained pressure exceeding 40 mmHg, while stockings offer convenience for maintenance. Adjustable wraps provide adaptable tension and may suit patients with fluctuating leg volume.
Proper application requires ensuring ankle pressure is highest and gradually decreases toward the knee to encourage upward blood flow. Clinicians measure leg circumference and fit bandages with consistent overlap. Incorrect technique can cause pressure points or slippage, undermining healing progress.
Compression therapy doubles healing rates for venous ulcers and reduces recurrence by up to 70 percent, while also alleviating pain and swelling. Contraindications include severe peripheral arterial disease, acute systemic infection and heart failure, where increased venous return may exacerbate conditions. Compression therapy types vary by patient need and clinical assessment, ensuring tailored pressure profiles deliver optimal support and promote sustained healing.
Effective wound care combines thorough cleansing, selective debridement and appropriate dressing selection to maintain a moist, controlled environment conducive to cell regeneration. Cleansing removes debris and bacteria, while debridement eliminates necrotic tissue, stimulating granulation. Choosing dressings that balance exudate management, infection prevention and moisture retention accelerates epithelialisation.
Cleansing uses gentle solutions such as saline to flush contaminants without harming healthy tissue. Debridement methods include surgical removal of devitalised tissue, autolytic debridement via moisture-retentive dressings and enzymatic agents that selectively digest necrotic areas. Each approach restores a viable wound bed.
Dressing choice depends on ulcer exudate level and infection status. Hydrocolloids support autolytic debridement in low-exuding wounds, alginates absorb heavy exudate, foam dressings cushion and retain moisture, and antimicrobial dressings prevent bacterial proliferation.
Infection control involves regular wound assessment, use of topical antiseptics or silver-impregnated dressings and systemic antibiotics when indicated. Early detection of increasing exudate, malodour or surrounding cellulitis prompts escalation of antimicrobial intervention.

Selecting the right dressing ensures a balanced wound environment, setting the stage for advanced therapies when necessary.
Chronic leg ulcers that resist standard treatment for over three months may benefit from specialised interventions that target underlying pathology and enhance tissue regeneration. Surgery, hyperbaric oxygen and negative pressure wound therapy (NPWT) stimulate healing through mechanical, physiological and cellular mechanisms.
Surgical options such as venous ablation and skin grafting are indicated when compression and conservative care fail. Venous ablation corrects reflux, restoring one-way blood flow, while split-thickness skin grafts cover large defects, providing a scaffold for healing.
Hyperbaric oxygen therapy delivers 100 percent oxygen under increased atmospheric pressure, elevating tissue oxygen tension. Enhanced oxygenation promotes fibroblast activity, neovascularisation and collagen synthesis in chronic wounds.
NPWT applies sub-atmospheric pressure to wounds, removing exudate and stimulating cell proliferation. Growth factor applications, including platelet-derived preparations, deliver cytokines that drive angiogenesis and matrix formation for refractory ulcers.
A multimodal approach that integrates advanced therapies offers relief when conventional measures stall, reducing healing times and improving outcomes.
Pain control and infection prevention are essential to patient comfort and successful healing. Combining pharmacological strategies with self-care practices reduces inflammatory burden while safeguarding the wound from microbial invasion.
Analgesia may include oral non-steroidal anti-inflammatory drugs to reduce inflammation-induced pain, topical lidocaine formulations for localized relief and, in severe cases, low-dose opioid regimens under close supervision. Adequate pain control supports mobility and self-care adherence.
Systemic antibiotics target suspected or confirmed wound infections, guided by culture results when possible. Typical regimens cover common skin flora, and therapy duration aligns with infection severity, ensuring eradication without promoting resistance.
Daily inspection, gentle cleansing, proper dressing changes and limb elevation minimise bacterial entry and oedema. Maintaining glycaemic control in diabetic patients further bolsters immune function and wound defence.

Effective pain management and infection control underpin patient well-being and prolonged healing momentum.
Preventing ulcer recurrence relies on sustaining vascular health, skin integrity and patient engagement in long-term self-management. Lifestyle adjustments that reduce venous pressure, enhance arterial flow and support metabolic balance form the foundation of ongoing care.
Regular exercise, such as daily walking or calf raises, enhances calf muscle pump function and venous return. A balanced diet rich in protein, vitamins C and D and zinc supports collagen formation, while smoking cessation improves microcirculation. Maintaining healthy body weight alleviates pressure on lower-limb vessels.
Elevating the leg above heart level for 30 minutes multiple times daily reduces oedema by facilitating fluid drainage. Complementary exercises like ankle pumps stimulate venous outflow, decreasing stasis and skin tension that predispose to ulcer development.
Regular review by tissue viability nurses, vascular specialists and podiatrists ensures early detection of recurrence signs, optimisation of compression systems and timely surgical or endovascular assessment when necessary. Structured clinics track healing progress and adjust care plans.
