The rectus abdominis muscle is versatile alone or as a musculocutaneous flap and useful for defects of moderate size requiring well vascularized tissue in the extremities. The muscle is long, thin and thus well suites for the hand, anterior tibial and ankle defects. The anatomical location makes dissection convenient for the working teams simultaneously in the same field. Authors have performed rectus abdominis free muscle transplantation in 10 cased to fit defects or cavities in the lower extremities at Chonbuk National University Hospital from June 1992 through August 1994. The results were as follows: 1. 7 cases of the 10 were exposed lower extremities from the vehicle trauma and rectus abdominis free muscles were transplanted at average of the 40th hospital day. 2. In chronic osteomyelitis, saucerization and parenteral antibiotics infusion therapy were combined with in 2 cases. 3. 9 of 10 cases were in complete success except 1 case, 67-yrs-old female, who was sustained the high-energery motor vehicle trauma. 4. Split thickness skin graft was performed on the well-grown surface of the rectus abdominis muscle in the extremities at the 4th postoperative week and taken well without any complications.

Desmoplastic fibroma of bone is rare, involves usually long bones, and histologically resemblance to the desmoid tumor of soft tissue. It is benign, but aggressive locally. Recurrence rate is high when treated with simple curettage and bone graft. Moreover, malignant transformation of desmoplastic fibroma with recurrence has been reported very rarely, and then it make us review again whether previous tumor probably was low grade malignant tumor. We report a surgically proven case of osteosarcoma arising from desmoplastic fibroma. A 17 years old male had been treated for a desmoplastic fibroma of the proximal tibia with curettage and bone graft. But after 11 years, the patient showed recurrence accompanying malignant transformation with osteosarcoma. This is very rare case of an osteosarcoma arising in a desmoplatic fibroma of the proximal tibia.

Osteosarcoma is the most common tumor in malignant bone tumors. The peak age incidence in osteosarcoma is between 10 to 14 years of age. This tumor rarely develops under 6 years of age and the youngest patient in the previous literature was a 13 months old girl who had an osteosarcoma involving the second metacarpal bone. We report a case of an 8 month old male infant, who had an osteosarcoma involving the right proximal tibia. This patient was treated by wide excision with transepiphyseal resection and reconstruction with allograft. At 20 months after operation, the varus deformity was developed at the proximal junctional site of allograft. Thereafter, the revision was performed with correction of deformity and augmentation with the proximal fibula transfer. At 51 months after operation, he has been remained as free of disease, and he has recovered the knee motion ranged from 15 degree to 75 degree. The osteosarcoma in infant is very rare but it should be considered the osteosarcoma in the differential diagnosis of any bone lesion. Instead of amputation, the limb sparing operation and the solutions for limb length inequility in growing period should be carefully considered in the infantile osteosarcoma.

Benign intraosseous osteolytic lesions of the glenoid are very rare. The present study reports on three cases of symptomatic intraosseous osteolytic lesions of the glenoid in which surgical interventions were made. Of the three, two cases presented with intraosseous ganglion and one case with fibrous dysplasia. In all the cases, the lesion was located at the posteroinferior portion of the glenoid, and it seems to be related to posterior shoulder pain. If intraosseous osteolytic lesions have symptoms or the risk for chondral defects or cortical breakage, surgical intervention is needed and bone curettage with or without bone grafting will be a useful treatment option.

Enchondroma is a benign tumor mainly developed in the hand and uncommon in the foot. Even if it is in the foot, most are in the phalanges and distal metatarsals of the foot. Enchondroma in the calcaneus is very rare. A 44-year-old male suffered from left heel pain for several months, authors treated it with curettage and bone graft, it was histologically confirmed as an enchondroma in the calcaneus. The authors presented a rare case presentation of an enchondroma in the calcaneus with pain.

신경외과는 뇌수술과 척추수술로 나눈다. 이중뇌수술 분야에서는 두개강내압 항진시 감압술이라고 '머리의 뚜껑을 연다'라는 표현과 마찬가지로 두개골의 일부분(손바닥크기)을 절제하는 수술이 있다. 이때 과거에는 떼어낸 뼈를 복부의 피하지방밑에 심어서 보관을 하다가 3-6개월 후 환자의 뇌상태가 안정이 되면 다시 꺼내어 제자리에 놓았는데, 골편이 피하지방에서 녹는 경우가 다소 있고, 복부에 이식한 장소가염증이 생기는 경우도 있어서 요즘은 냉동고에서 -70도를 유지하여 보관 후 나중이 복원 수술을 할 때녹여서 사용한다. 이를 '자가골 두개성형술' 이라 한다. 하지만골편의 오염이나 소실 혹은 1차 두개성형술 후 감염 등 어쩔 수 없이 자가골을 사용 못하는 경우에는인공으로 두개골편 모형을 제작하여 '뚜껑'으로 사용해야 한다. 현재PMMA를 이용하여 수술 시 모형을 제작하는 방법이 많이 사용되며 최근 단단한 스펀지 형태의 인공제품이 사용되고 있으나 가격이 매우비싸지만 스펀지 기공내로 자가골이 자란다는 장점이 있다. 척추수술 분야에서는 뼈 대치품을 비교적 많이필요로 한다. 즉 척추 후방고정을 하는 경우 원래 수술의 목적인 감압술이나 교정술 등을 한 후 척추분절간 쇠(티타늄사용)고정을 한 뒤에 뼈조직(자가골이나 동종이식골, DBM, HA stick) 등을 충분히 사용하여덮어줌으로써 분절간 골유합을 유도할 때 많은 양이 필요하며, 척추 전방으로 수술을 하는 경우에도 디스크공간이 빈 상태에서 Cage(추체와 추체를 지지하는 작은 상자모양) 내에뼈조직을 넣어서 척추분절간 골유합이 일어나도록 한다. 최근 HA를 cage 대용품으로 사용한 경우에서 HA가 부서지는 경우가 기사화된바 있다. 또한 경추의 추체 내에 작은 구멍만 뚫고 디스크 수술을 한 후에 그 구멍에 HA+B-TCP 소재를 넣어 천연뼈의 성장 유도를 위해 사용되는 등 신경외과의 다양한 분야에서 생체소재들이 사용되고 있다.

2000년대에 있어서 세계의학계는 인공심장의 완성과 인공신장, 인공 간, 인공수족과 인공골, 관절, 혈관 등의 인공장기이식의 눈부신 연구, 발전에 의하여 인간의 수명은 더욱 연장될 것이며 사망률을 낮추는 치료의학은 한없이 발전하게 될 것이다. 치과의학의 과제는 상실된 치아와 악골, 구강내외 장기의 수복을 위한 인공치아 및 장기이식의 치료요법의 발전이 될 것이다. 인공치아 치료요법의 한가지인 nonsubmerged and one stage operation type인 I.T.I. 임프란트 시스템은 골성접착과 결합이 이루어지는 인공치아 이식술로서 그 단순한 시술과 높은 성공률에 의해 전세계에 각광을 받는 치료방법의 하나이다.
