A corn is a circumscribed hyperkeratotic lesion with a central conical core of keratin that causes pain and inflammation. Corns result from hyperkeratosis, which is caused by an increase in keratinocyte activity associated with stimulation of the epidermis from chronic pressure or friction on the skin. The conical core in a corn, which is a thickening of the stratum corneum, is a protective response to the mechanical trauma. We experienced a man who developed a corn on the buttock, which is an unusual site.

Acquired digital fibrokeratoma (ADFK) is a solitary round, firm and hyperkeratotic projection seen most commonly on the digits, but it is occasionally found on the palm, dorsum of the hand, wrist, periungual area, and rarely on the sole. We report herein three cases of ADFK in an adult occuring on the sole. As being continuously exposed to the pressure, ADFKs are transformed and may easily be mistaken for more common plantar lesions including plantar warts and corns.

PURPOSE: Painful plantar callosities under the second, third or fourth metatarsal head have been controverted about its treatment mordalities. We performed the vertical chevron osteotomy in patients with painful callosities on the second and third metatarsal head, and evaluated the outcome clinically. MATERIALS AND METHODS: Fourteen cases from 10 patients who had plantar keratosis were operated by vertical chevron osteotomy from March 2005 to October 2008. We used K-wire fixation for all cases. We evaluated the clinical results by the patients' satisfaction and disappearance of plantar lesion. RESULTS: The plantar keratosis was completely disappeared in 8 cases and partially in 5 cases. In 2 cases, patients expresses their pain caused by constant metatarsalgia that was suspected to be dorsal incisional pain and joint capsulitis. Transmetatarsalgia was not appeared. CONCLUSION: We consider vertical chevron osteotomy as a good surgical method for treatment of plantar keratosis.

The skin defects or sensory impairment of the fingers, especially at the critical area for prehension(tips of thumb, index and middle fingers) should be reconstructed for the better function of hand. In our department, we performed neurovascular island pedicle flap transfer for the purpose of reconstruction of sensibility and skin defect simultaneousely to the critical area. 1. Since 1978, we had performed neurovascular island pedicle flap transfer in 14cases, among which 9 cases were followed for more than one year. 2. The operation was performed for the reconstruction of thumb in 8 cases, and index in 4 cases. The most common cause of injury was crushing by machine(8 cases). 3. The island flap was transferred from middle finger(9 cases) and from ring finger(4 cases). 4. Recovery of the protective sensation at the recipient sites was good or fair after one year, but reorientation and two point discrimination were poor. 5. Cold intolerance was developed in 3 cases and callosity was formed in 2 cases. 6. In all cases, the transferred flaps were good in circulation status and durability. 7. It is considered that the neurovascular island pedicle flap is an accepted method of restoring skin coverage as well as sensation to a localized tactile area in the hand.

PURPOSE: The authors intended to evaluate the results of symptomatic bunionette treated with a diaphyseal oblique osteotomy. MATERIALS AND METHODS: Nine patients were followed for more than 1 year after diaphyseal oblique osteotomy for a bunionette deformity with plantar callosity. The mean age was 43 years (23-69 years), and the mean follow-up period was 27 months (12-70 months). As a combined disorder, 7 patients had hallux valgus, for which 3 distal metatarsal oteotomies, 3 proximal osteotomies, and 1 double osteotomy were performed. Clinically, preoperative and postoperative AOFAS MP-IP scale, patient's satisfaction, postoperative complications were analyzed. Radiologically, the 4th intermetatarsal angle and the 5th metatarso-phalangeal angle were analyzed. RESULTS: Clinically, AOFAS MP-IP scale was increased from 59 points preoperatively to 93 points postoperatively, and all patients were satisfied with the results. The plantar callosity had all disappeared at the final follow up. The 4th intermetatarsal angle was decreased from 12.6degrees preoperatively to 4.3degrees postoperatively, and the 5th metatarso- phalangeal angle was decreased from 21.9degrees preoperatively to 2.4degrees postoperatively. There were no significant postoperative complications. CONCLUSION: Diaphyseal oblique osteotomy of the 5th metatarsal appears to be safe and satisfactory procedure for the treatment of a symptomatic bunionette with plantar callosity.

In general, the operative treatment of the brachymetatarsia is the lengthening of the affected metatarsal bone due to the cosmetic problem rather than the functional one. We experienced 22 year-old female bilateral congenital foot deformities such as hallux varus and 1,4th brachymetatarsia treated with reverse Scarf osteotomy on the hallux varus and massive axial metatarsal shortening Weil osteotomy on the 2,3,5th metatarsals which could reconstruct the normal metatarsal parabola.

PURPOSE: The purpose of our report was to evaluate the result of operative treatment of hallux valgus in old age patients. MATERIALS AND METHODS: We studied about the clinical & radiologic results of the 31 patients over 55 years old, who had operative treatment of hallux valgus. Clinical evaluation, such as pain, activity limitation, footwear requirement, 1st metatarsophalangeal joint motion, and callosity, was done using AOFAS scale and preoperative and postoperative radiologic parameters, such as hallux valgus angle, intermetatarsal angle, tibial sesamoid position, 1st metatarsal shortening, were evaluated by conventional methods. RESULTS: Objectively, according to AOFAS, the score improved from average of 57.8 to 71.5 postoperatively. The range of motion of first metatarsophalangeal joint was decreased from average of 60.7 to 56.8 degrees. Radiologically, the hallux valgus angle improved from average of 35 to 6.5 degrees and the first intermetatarsal angle improved from average of 14.2 to 4.4 degrees. The position of sesamoid was collected from an average of grade 3.6 to grade 2.2. CONCLUSION: The combination of proximal metatarsal osteotomy, distal soft tissue procedure and Akin osteotomy may yield rather satisfactory clinacal result in severe elderly hallux valgus patients with massive degenerative change and poor soft tissue condition.

Foot problems are common in elderly patients, and the relief of foot pain can increase the rehabilitative potential for patients with chronic diseases, impairments, or disabilities. The author presents a detailed description of techniques for the clinical management of hallux valgus, plantar fascitis, callosities, and myofascial pain syndrome. The focus is clinical and practical, i.e., based upon common foot conditions seen in clinical practice.
