The advent of free bone flaps has made successful replacement of extensive areas of bone loss in the upper and lower extremities. The microvascular free bone flaps have faster healing without bony absorption or atrophy and can heal in the hostile environment of scarred bed or infection. Since the fibula free flap introduced by Taylor and colleague in 1975, it has been used extensively for skeletal reconstruction of extremities. In 1988, the folded vascularized fibula free flap was first described as a technique to reconstruct significant long bone defect of upper and lower extremities. During the same time, the fibular free flap has evolved to become most preferred choice of mandibular reconstruction. Up to present day, few reports have been made on the fibular free flap used for reconstruction of injured hand containing metacarpal bone and soft tissue defect. We present here our new and unique experiences with vascularized fibular osteocutaneous free flap as useful and satisfactory one for reconstruction of hand with composite defects.

Since the first report by Tansini in 1896, the latissimus dorsi muscle free flap has been widely used for various types of soft tissue defect due to reliable anatomy with a sufficient diameter of neurovascular pedicle and a sizable muscle. However, for relatively small soft tissue defect, latissimus dorsi free flap offers several distinct disadvantages of donor site including loss of the posterior axillary fold and flattening of the posterolateral chest wall, weakness of upper arm strength in extension, adduction and internal rotation. We treated three patients having various types of soft tissue defect using segmental latissimus dorsi muscular free flap depending on its descending branch of thoracodorsal neurovascular pedicles. There were no serious complications during 18 months of mean follow-up. We concluded that this method has some advantages such as no weakness of strength of the upper arm including walking on crutches, preserving the posterior axillary fold, preventing winging of the scapula and increased chance of using a flow-through technique. Here we present our cases of reconstruction of soft tissue defect using segmental latissimus dorsi free flap with a review of the literature.

원자력 발전소에서 발생되는 방사성폐기물을 한 곳에 모아 집중관리하기 위한 방사성폐기물 처분장의 부지선정이 국가적 과제로 부각되어 있으며, 충분한 검토를 거친 후 임해부지로 선정될 것이다. 이로 인하여 현재 각 원전부지내에 임시로 보관되어 있는 방사성폐기물에 대하여 전용선박에 의한 해상수송을 하여야 하며, 한국원자력연구소의 원자력환경관리센텨(NEMAC)에서는 원전부지로부터 처분장까지 안전하고 효율적으로 방사성폐기물을 수송할 수 있는 종합해상수송체계를 개발중에 있다. 이 글은 해상수송체계가 갖추어야 할 수송선박의 기술기준을 설정하기 위한 것으로, 원자력 선진국의 진보된 방사성폐기물 해상수송기술에관한 현황을 조사. 분석하고 국내의 제반여건을 고려하여 우리나라에서 사용될 수송선박의 설계 및 건조추진방향을 제시하였다. 따라서, 만일의 사고에도 방사성물질이 선박의 외부로 누출되지 않는 개념의 선박을 설계. 건조하여 방사성폐기물을 안전하게 해상수송하게 될것이다. The site of Korea Final Repository, KFR, to collect and dispose of radioactive wastes produced in nuclear power plants will be selected to seaside. As all the radwastes stored temporarily in the site of power plants should be transported by the sea. Nuclear Environmental Management Center, NEMAC, of Korea Atomic Energy Research Institute, KAERI, has been developing the sea transport system to secure safe and effcient transportation of the radwastes from the power plant sites to the final repository. Investigating the status of advanced techniques of foreign countries for transpkort vessels and considering inland circumstances, the technical criteria of the transport vessel have been suggested in this study. Therefore, all the radwates will be transported safely by the sea, without releasing any radioactive material to environment even the case of accident.
