With the continuous development of diagnostic techniques of precancerous lesion and an improved patient-transfer system, it is unusual to examine patients who have a life-threating malignant skin lesion. However it is still a problem in some far-advanced inoperable skin tumors which have been neglected and have become aggravated, Another problem in oncologic surgery is previous irradiation around a lesion. The only effective way to treat these lesions is to excise widely and cover with an appropriate free flap. But in such conditions, selection of recipient vessel is not easy. Many surgeons have used vein graft as the conduit from a distant non-radiated vessel to the free flap. This technique requires a long segment of vein for anastomosing both the artery and vein. We used intra-lesional vessels as the recipient vessel of the free flap, which were suspiciously damaged by irradiation and malignant cell infiltration. The guidelines include: 1) malignancy-infiltrated vessels are to be dissected until a clear field is obtained under a frozen section 2) irradiated vessel can be used only if active spurting is present without intraluminal thrombosis. All of our case obtained satisfactory results in all cases except one of irradiated squamous cell carcinoma at inguinal area whose gracilis myocutaneous free flap loss was in 10%. But even this case, the cause of partial loss of the flap may not be due to a vascular problem but an internal failure of the flap. We concluded, that carefully selected intra-lesional vessels, although they may be damaged by irradiation or malignant cell infiltration can be used as the recipient vessels of free flaps.

2.Teh Effect of Local anesthetic on Degeneration and Regeneration of the Experimentally Traumatized Striated Muscle
The Journal of the Korean Orthopaedic Association 1995;30(5):1119-1129
The repair of striated muscle after acute trauma occurs simultaneously by the regeneration of disrupted muscle and formation of connective scar. But, there had been no attention concerning effects of local anesthetics on the degeneration and regeneration process of the injured muscle. The author induced a constant contusion injury on the calf of rats. Lidocaine and/or epinephrine was intramuscularly injected at the site of injury. Morphological and histochemical observation was conducted and the results were as follows: 1. Traumatized striated muscle showed evidences of the healing process for upto 90 days. 2. Morphological and histochemical changes in the traumatized muscle became more severe after the injection of lidocaine and/or epinephrine. 3. Formation of collagenous scar tissue significantly increased after injection of lidocaine and/or epinephrine. Injection of lidocaine or epinephrine developed similar amount of scar after 15 days. 4. Cross section area of the regenerated muscle fibers decreased in the injection groups than in the control groups. Atrophy was significant on day 90 in all types of fiber after injection of the mixture of lidocaine and epinephrine, and in type B after injection of epinephrine. In conclusion, injection of the lidocaine and epinephrine inhibited regeneration of the traumatized striated muscle. Mixture of the drugs showed more inhibitory effect than a single drug.

3.Supramalleolar Stepcut Osteotomy for Tibial Deformity in Vitamin D
The Journal of the Korean Orthopaedic Association 1984;19(6):1103-1108
In treatment of Vitamin D-resistant rickets, the authors supplemented supramalleolar stepcut osteotomy for complex deformity of tibia consisted of varus, anterior bowing and intemal torsional supramalleolar level which accompanied severe waddling gait. The results of 10 tibia operations from 5 patients were generally satisfactory in terms of appearance and function.
