Foot, nail and wound care are among the most frequently requested nursing procedures outside hospitals - and yet, for many people, accessing them without waiting weeks in the emergency room or having a family doctor remains a real challenge in the Quebec context. A painful ingrown toenail, a post-surgical wound requiring regular dressing changes, a chronic leg ulcer or an invasive nail fungus are not trivial situations: left untreated or poorly managed, they can develop into serious complications, particularly in people with diabetes, immunodeficiency or reduced mobility.
Clinique Omicron offers specialized nursing care of feet, nails and wounds at several of its branches in Quebec - performed by clinical nurses trained in advanced wound care techniques, with access to on-site medical assessments when clinically required.
Ingrown toenail and onyxis: diagnosis and medical treatment
Ingrown toenail (onychocryptosis) occurs when the lateral edge of the nail - most commonly the hallux (big toe) - penetrates the adjacent skin, causing pain, local inflammation and the risk of secondary infection. There are three progressive stages of severity: stage 1 is characterized by pain on pressure and slight redness without infection; stage 2 presents granulation tissue (fleshy buds) and serous or purulent oozing; stage 3 involves frank tissue infection with suppuration, significant granuloma and sometimes deformation of the nail matrix. Management depends on the stage. In early stages 1 and 2, conservative techniques may suffice: placement of a splint or nail splint, drainage of the painful area, care of the periungual skin and advice on correct nail trimming. In advanced stages 2 and 3, or in cases of recurrence, partial or total resection of the nail with destruction of the matrix under local anaesthetic (phenolization) is the reference treatment, performed in the clinic under aseptic conditions.
Mycotic onyxis (onychomycosis) is a fungal infection of the nail, caused in 90 % of cases by dermatophytes (mainly Trichophyton rubrum) and more rarely by yeasts (Candida) or molds. It manifests as progressive thickening of the nail, discoloration (yellow, brown or white), brittleness and detachment of the nail plate from the distal edge (onycholysis). Clinical diagnosis should ideally be confirmed by mycological sampling (culture or PCR) before prolonged antifungal therapy is instituted, as other conditions may mimic onychomycosis (nail psoriasis, chronic trauma, paronychia). Systemic treatment with terbinafine (250 mg/d for 6 weeks for fingernails, 12 weeks for toenails) offers the best mycological cure rates (70-80 %), but requires hepatic monitoring in some patients. Topical treatments (amorolfine, ciclopirox, efinaconazole) are less effective as monotherapy, but may be suitable for milder forms or as a complement to systemic treatment.
Wound care and dressing changes: wound types and treatment principles
The management of acute and chronic wounds is based on precise clinical principles that go beyond simple cleaning and dressing. The initial assessment of a wound includes evaluation of its size, depth, location and type of tissue present (necrotic, fibrinous, granulation or epithelialized tissue), evaluation of exudate (quantity, appearance, odor), search for signs of local infection (heat, peripheral redness, purulent exudate, odour, increasing pain, poor budding) or systemic infection (fever, lymphangitis), and the patient's medical context (diabetes, venous insufficiency, anticoagulant treatment, immunodepression). The choice of dressing is guided by these factors: absorbent hydrocellular dressings for highly exudative wounds, hydrogels for dry or necrotic wounds requiring rehydration, alginates for bleeding wounds, silver dressings for infected wounds or those at high risk of infection, non-adherent interface dressings for fragile wounds.
Chronic wounds are a category in their own right, requiring specific expertise. Venous leg ulcers - the most frequent, accounting for 70 % of chronic lower limb ulcers - result from chronic venous insufficiency with venous hypertension, and require therapeutic compression (bandages or compression stockings graduated at 30-40 mmHg) in addition to local wound care, after exclusion of underlying obliterating arteriopathy by measurement of the systolic pressure index. Arterial ulcers (obliterative arteriopathy of the lower limbs) present a different picture - painful wound, sharp edges, pale or necrotic background, absent distal pulses - and do not tolerate compression; they require revascularization. Diabetic foot wounds are a relative clinical emergency, as they heal poorly due to peripheral neuropathy (insensitivity to trauma), microangiopathy and the relative immunodepression associated with poorly controlled diabetes - the risk of osteomyelitis and amputation justifies multidisciplinary management and close monitoring.
Nursing foot care in the context of diabetes and vulnerability
The diabetic foot is one of the most dreaded complications of diabetes: in Canada, a diabetes-related amputation occurs every 30 minutes, and the vast majority of these amputations are preceded by a foot sore. Prevention relies on regular follow-up by a healthcare professional: minimum annual foot examination (monofilament to test sensitivity, tuning fork for vibratory sensitivity, palpation of posterior tibial and pedal pulses), identification of at-risk feet (deformities, calluses, dry skin, interdigital mycosis), regular care of nails and calluses, education on daily foot inspection, skin hydration, choice of suitable footwear and prohibition of barefoot walking. Diabetic patients with established peripheral neuropathy are a priority population for regular podiatric nursing care, enabling early detection of any lesions before they develop into chronic infected wounds.
Frequently asked questions about foot, nail and wound care
My ingrown toenail has been hurting a lot for the past few days. Should I go to the emergency room or can I go to the clinic?
The vast majority of ingrown toenails, even painful ones, do not require a trip to the hospital emergency room - they can and should be managed in a primary care clinic. Emergencies are only warranted if you have signs of severe infection: redness and warmth that progress rapidly beyond the toe to the foot, a red trail upwards towards the ankle (lymphangitis), fever, or if you are diabetic or immunocompromised with a worrying wound - in these cases, a deep tissue infection (cellulitis, necrotizing fasciitis) needs to be ruled out quickly. In non-emergency situations, a visit to the clinic will enable you to make a precise clinical assessment of the stage and possible infection, provide appropriate treatment (conservative care or nail resection, depending on the stage), prescribe antibiotics if bacterial infection is confirmed, and offer advice on preventing recurrence. Waiting to self-medicate with home remedies simply risks letting the infection progress to the next stage.
My post-operative wound needs regular dressing changes. How can I organize this follow-up at the clinic?
Surgical wounds often require regular dressing changes once the patient has returned home - the frequency varying according to the type of operation, the type of closure (sutures, staples, wounds left open for secondary healing), and the evolution of the wound. This care can be provided by Clinique Omicron's nurse clinicians, either on medical prescription or as part of post-operative follow-up care. It's a good idea to bring your operative report or discharge instructions with you to your first consultation, as well as the specific material prescribed if your surgeon has recommended a particular type of dressing. The nurse clinician will assess the wound at each visit, documenting its progress and alerting the doctor if signs of complication appear - infection, dehiscence (wound opening), necrosis of the wound edges. RAMQ generally covers nursing care of wounds in the context of post-surgical follow-up; fees may apply, depending on the context and the type of equipment used.
Can toenail fungus be treated at the clinic, or does it have to be seen by a dermatologist?
Onychomycosis can be diagnosed and treated in a primary care clinic - a dermatologist is not required in the vast majority of cases. A medical consultation at the clinic first confirms the clinical diagnosis (and indicates mycological sampling if the picture is not typical, or before prescribing prolonged systemic treatment), assesses the extent of involvement and the number of nails affected, selects the appropriate treatment (topical for mild to moderate forms without matrix involvement, systemic with terbinafine for more severe or resistant forms), and checks for contraindications and drug interactions before prescribing an oral antifungal. Terbinafine requires caution in patients with pre-existing liver disease, and a check for interactions (CYP2D6 inhibitor: interactions with certain antidepressants, antiarrhythmics). A dermatological referral remains useful for atypical, resistant or diagnostically uncertain cases, or when nail psoriasis is suspected.
