Even thought the composite graft has many advantage, its clinical use has been limited survival. Early vascularization from the recipient site is essential for the survival of the composite graft. We grafted 15mm-sized composite tissue on the rabbit ear. And the rabbit was treated with hyperaric oxygen or calcium antagonist. The survival area, survival rate, gross and histologic change were studied using the biopsy specimen which was taken on 2nd, 5th, 7th, and 14th postoperative day. The result are as follows; 1. The survival rate of hyperbaric oxygen treated group(89.7%) was significantly higher than that of the control group(65.3%).(p<0.001) 2. The survival rate of the calcium antagonist treated group(67.5%) was not significantly higher than the control group(65.3%).(P>0.1) 3. The color of the graf was monitored. At postoperative 24-48 hours, the color of the graft truned into pink-tined tone, and than changed into purple color at postoperative 4th-5th day. The color of the graft returned to nomal pinkish hue at 7th-10th postoperative day. We observed the same color change in each groups of survived composite graft. 4. The histologic finding of the hyperbaric oxygen treated group was compaired to those of the control or calcium antagonist treated group. The hyperbaric oxygen treated group showed less degeneration of epithelial cells and chondrocytes as well as less interstitial edema, but it showed increased chondroblasts and chondrocyte layers. In conclusion, we noticed that the hyperbaric oxygen treatment significantly increases the survival of the composite graft.

This study was designed to compare the electrical efficiency of biceps brachii during 50% an 100% MVC test in the exercise player and non-exercise player. It was measured IEMG,MVC, 50%MVC, E/F ratio during Arm flexion. Significantly less E/F radio during 100%MVC and 50% MVC was appeared in exercise group compared with non-exercise group. This result suggested that exercise group during muscle force output had a good efficiency compared with non-exercise group, and that specificity of exercise related to muscle efficiency.

Percutaneous transluminal angioplasty (PTA) has proved to be a safe and effective treatment for stenois of vessels, and became an important adjuvant and a viable alternative to surgical correction of ischemic vascular disease of lower extremity. Complications from PTA include dissection, occlusion, embolization, and rupture. The most important complication occurring at the angioplasty site is acute occlusion attributed to thrombus. We experienced the acute thrombosis patient after PTA for femoropopliteal arteriosclerosis, and attempted to catheter directed thrombolysis, but this effect was to no avail and thus, we extracted the thrombus by simple thrombectomy. Thereafter the patient came to have good pluse and was free of rest pain.

수부손상 후 발생한 Intrinsic contracture의 치험례

A fine balance of the intrinsic and extrinsic muscles of the fingers provides the hand with its normal strength and exquisite versatility. When this balance is upset by contracture of the interossei, lumbricals, or hypothenar muscles, the fingers stiffen and the hand becomes disabled. Ischemic contracture of the intrinsic muscles of the hand is the result of ischemia and secondary intrinsic muscular retraction localized at the intrinsic muscles of the intermetacarpal compartments. Severe involvement of the interossei causes the hand to take up the characteristic "intrinsic plus deformity' with the metacarpophalangeal joints held flexed and the proximal interphalangeal joints extended. This results in a crippling loss of such vital functions of the hand as pinch and grasp. There is the importance of preventing severe and persisting edema of the hand. After injury the limb is elevated, and early fasciotomy of the different compartments of the hand is indicated when the surgeon believes that the intrinsic muscles are ischemic. The surgical procedures of preference to correct the estabilished deformity depend on the severity of the muscular retraction and deformity and the localization of the pathology. We report one case of post-traumatic intrinsic contracture with metacarpophalangeal flexion contracture after crushing injury of right wrist. In our cases, we performed surgical release of the intrinsic contracture by proximal intrinsic release, palmar metacarpophalangeal joint release, and collateral ligament release. By these methods, we were able to achieve sufficient release of the metacarpophalangeal flexion contracture, which increased range of motion about 40 to 60 degree, and good functional results of the hand.

There has been a considerable improvement in the understanding of pathophysiology of burn and its treatment in recent year. The mortality for unselected cases of burns has been declined during last few decades. However, mortality from severe burns remains to be very high. In recent journal, several methods has been named to improve this high mortality. One of our effort focused on skin graft to reduce this high mortality. During the past 3 year period from May. 1971 to May. 1974, 224 cases of burn patient had been treated at surgical department of Woo Sok hospital of Korea University. Clinical analysis of these 224 cases of burn patient were carried out and summarized as follows; 1) Age and Sex distribution: Between 1 to 9 years old children were most commonly involved (51.6%) and male were affected twice than females. 2) Sesonal distribution: Most patients were occured in June, July and August, 71 cases (31.7%). 3) The causes of burn are as follows: Scalding 127 cases (56.6%), Flame 78 cases (34.9%), Chemical 12 cases (6%). 4) The extent of burn: 11%∼30% burn surface area is most common, 108 cases (48%). 5) For the fluid therapy of burn cases, Evans formula was employed in most children and Brooke's formula in adult patients. The result of these treatment was excellent in 121 cases (54%) and expired in 58 cases (26%). 6) There were 58 deaths (26%) in all. Among of these, 32 cases(55.2%) were succumbed by the wound infections and septicemia, 8 cases(13.8%) were due to burn shock 7) Skin graft was performed in 48 cases(21.4%). Skin graft was performed mostly between 2 to 3 weeks, as late as 4 weeks. 8) Period from skin graft to discharge was within 2 weeks in 19 cases (39.6%), within 3 weeks in 12 cases (25%), and within 4 weeks in 7 cases (14.6%). 9) Success rate of skin graft was over 90% in 42 cases (87.6%), and 70∼90% was 5 cases (10.4%).
