Glossary

A
Angiography Method to visualize blood vessels.
Angioplasty Re-establishment of an arterial lumen by percutaneous transluminal or subintimal instrumentation/technique: a special tube containing an inflatable balloon is inserted into a blocked or narrowed artery. The balloon is inflated to clear blockages, widen the artery and thus improve the blood flow.
Amputation Resection of a terminal part of a limb.
Anti-platelet therapy (Preventive) treatment with drugs to inhibit excessive clotting of platelets in the blood.
Arthritis Inflammation of a joint.
Athletes foot Fungal infection between the toes.
B
Bullae Blisters.
C
Callus Formation of horny tissue due to mechanical stress.
Cardiovascular diseases Diseases of the circulatory system, including those affecting the heart and blood supply.
Charcot-foot Non-infectious destruction of bone and joint associated with neuropathy: Neuro-osteoarthropathy.
Claudication Pain in foot, thigh or calf during walking, which is relieved by rest and is combined with evidence of peripheral artirial disease.
Cellulitis Presence of induration, swelling, redness, heat, local pain or tenderness. Indicating an inflammatory reaction, irrespective of cause.
D
Debridement Removal of dead tissue.
Deep infection Evidence of abscess, septic arthritis, osteomyelitis or septic tenosynovitis.
Deep ulcus Full thickness of the skin extending the sub cutis, which may involve muscles, tendon, bone and joint.
Diabetic foot Infection, ulceration and /or destruction of deep tissue associated with neurological abnormalities and various degrees of peripheral vascular disease in the lower limb.
Diabetic neuropathy Presence of symptoms and/or signs of peripheral nerve dysfunction in people with diabetes, after exclusion of other causes.
Doppler A machine that can detect the movement of blood cells within the blood vessel and measure blow flow.
Dyslipidaemia High levels of fat in the blood.
E
Edema Swelling of the foot sufficiently pronounced to leave a clear imprint of pressure by a finger.
Erythema Redness.
F
Foot deformity Structural deformities in the foot such as presence of hammertoes, claw-toes, hallux valgus, prominent metatarsal heads, status after neuro-osteoarthropathy, amputation or other foot surgery.
Foot lesion Blister, erosion, minor cut or ulcer on the foot.
Fissures Cracks, splits and small cuts.
Fulminant Fast spread of the disease.
G
Gangrene Necrosis (mortification) of the skin and underlying structures (muscles, tendon, joint or bone) with irreversible damage where healing can not be anticipated without loss of some part of the extremity.
H
Hallux valgus Deformity of the big toe.
Hyperglycaemia (Too) high glucose levels in the blood, leading to ketoacidosis and recurrent of persistent infections.
Hyperkeratosis Formation of horny tissue.
Hypertension (Too) high blood pressure.
Hypoglycaemia (Too) low glucose levels in the blood, leading to confusion and loss of consciousness.
I
Infection Invasion and multiplication of pathogenic micro organisms in body tissues.
Ischaemia Signs of impaired circulation verified by clinical examination and/or vascular testing.
K
Ketoacidosis A subsequent build up of acids (keto bodies) in the blood, resulting in a condition of acidosis and associated with high glucose levels in the blood.
M
Maceration Softening of the skin.
N
Necrosis Devitalized, dead tissue.
Diabetic nephropathy Disease of the kidneys (kidney failure) as a result from increasing amounts of protein in the urine due to high glucose levels in the blood.
Neuro-osteoarthropathy Non-infectious destruction of bone and joint associated with neuropathy: Charcot-foot.
Neuro-ischaemic The combination of diabetic neuropathy and peripheral arterial disease.
Neuropathy Nerve damage leading to numb feet.
Non-ulcerative pathology Other lesions than an ulcer.
O
Oedema Swelling of the foot sufficiently pronounced to leave a clear imprint of pressure by a finger.
Onychauxis Thickening of the nails.
Onychocryptosis Nail deformities such as ingrown toenails.
Onychogryphosis Deformities of the nails.
Orthosis An appliance which controls, corrects or accommodates a structural or functional abnormality.
Osteomyelitis Infection of the bone with involvement of bone marrow.
P
Peripheral arterial disease (PAD) Atherosclerotic disease of blood vessels in or leading to the extremities (hands and feet), resulting in narrowing or obstruction of these arteries.
Protective footwear Footwear designed to prevent ulceration.
Perfusion Restoring blood flow to the skin.
R
Diabetic retinopathy A non-inflammatory disorder of the retina as a result of small vessel damage in the retina due to high glucose levels in the blood.
Revascularization Improving blood supply through vascular surgery or angioplasty.
S
Superficial infection An infection of the skin not extending trough muscles, tendon, bone and joint.
Superficial ulcer Full thickness of the skin not extending the sub cutis.
Surgical bypass procedure A revascularisation technique in which a bypass graft is inserted into the blocked or narrowed blood vessel.
T
Therapeutic footwear Footwear designed to relieve biochemical stress on an ulcer and which can accommodate dressings.
Transcutaneous Through the skin.
Tenosynovitis Inflammation of the tendon sheath.
Tinea pedis Fungal infection on the foot.
Thrombosis Intravascular formation of a blot clot (thrombus).
U
Ulcer Sore; full thickness of the skin.
V
Verucca Small hard benign growths on the skin: warts.
