Do u know what kind of lesion it is?? I got this lesion few months ago. When I followed a competition for choosing collages ambassadors. And u know what, almost 3 days I wore the real high heels in the stage than i was walking too much at that day . . . Yeah, it's clavus. A clavus is a thickening of the skin due to intermittent pressure and frictional forces. These forces result in hyperkeratosis, clinically and histologically. The extensive thickening of the skin in a clavus may result in chronic pain, particularly in the forefoot; in certain situations, this thickening may result in ulcer formation. The word clavus has many synonyms and innumerable vernacular terms, these terms describe the related activities that have induced clavus formation. Synonyms for clavus include callosity, a hyperkeratotic response to trauma; corn, heloma, or a circumscribed hyperkeratotic lesion that may be hard (ie, heloma durum) or soft (ie, heloma molle); and callous, callus, or a diffusely hyperkeratotic lesion. Localized callosities of the soles, which do not resolve, are termed plantar callus, heloma, tyloma, keratoma, or plantar corn.When callosities occur over 1 or more lateral metatarsals, they are termed intractable plantar keratoses. Clinically, all these lesions look like hyperkeratotic or thickened skin. Maceration and secondary fungal or bacterial infections are a common overlying feature in heloma molle and diabetes. Plantar helomas tend to have a central keratin plug, which, when pared, reveal a clear, firm, central core. The most common sites for clavus formation are the feet, specifically the dorsolateral aspect of the fifth toe for heloma durum, in the fourth interdigital web of the foot for heloma molle, and under the metatarsal heads for calluses. Cause?? Conditions associated with clavus formation: -Advanced patient age -Amputation (ie, stump callosities) -Use of a brace or orthopedic stabilizing product -Bulimia nervosa -Costa acrokeratoelastoidosis -Doxorubicin toxicity -Keratoderma palmaris et plantaris -Obesity -Pachyonychia congenita -Sensory neuropathies, including neuroborreliosis -Tethered spinal cord syndrome -Vascular occlusion syndromes -Warts (ie, verruca vulgaris) Faulty mechanics: Irregular distribution of pressure and repetitive motion injury (especially in athletes) are believed to be the main inciting causes; however, inappropriately shaped or constrictive footwear in the presence of bony prominences (eg, talar bone prominences may exacerbate clavus formation. Furthermore, some disorders may alter the shape or sensation of the soles of the feet. Bony prominences and faulty foot mechanics then allow clavus formation to continue. -Rheumatoid arthritis : About 17% of patients with rheumatoid arthritis present with intractable foot pain. Chronic arthritis leads to foot deformities and consequent callus formation. Bleeding into callosities in patients with rheumatoid arthritis may be a sign of rheumatoid angiitis. -Diabetes mellitus with associated peripheral neuropathy : In patients with diabetes, chronic callosities in the presence of neurovascular deterioration may lead to ulcerations and superinfections. -Obsessive-compulsive disorder (pseudo-knuckle pads) -Ectopic nail And how about the treatment and management?? For this case we can do medical care, consultation,surgical care, diet, and activity management. And yeah, now i'm as a patient will get surgical care today. Because i have a chronic pain to be honest when i woke up, or when i wear my high heels. Surgical options for clavus should be used when only conservative measures fail. Chronic foot pain despite conservative therapy is the number one indication for surgery. Hallux valgus correction may aid in reduction of painful callosities over the long term. Surgical corrections for claw, hammer, and mallet toes are simple procedures. Shaving of prominent condyles of bony prominences may be beneficial particularly on the fifth digit. Arthroplasty of the fifth toe interphalangeal joint also may be performed. Metatarsal condylectomy or chevron osteotomy may be performed to relieve metatarsal head pressure. Mann and DuVries described the use of a combination of arthroplasty and condylectomy. This combination results in 95% clearance, with only a 13% occurrence of transfer lesions. When thinning of the plantar fat pads is contributory to the formations of callosities, injectable silicone can be used on the soles underneath the callosities and corns to reduce pressure related callous formation. Description of excision followed by either grafting, use of flaps, or grafting using split-thickness graft with or without a collagen/elastin matrix graft has been described as effective in a single resistant case. And yeps i hope my little operation can running well today :))) so, I won't be hurt in every single morning such always said duhh, duhh , aww it's really hurt, what a chronic pain ;(
