Thirty one free vascularized fibula bone grafts were performed for treatment of osteonecrosis of the femoral head in 26 patients, 24 men and 2 women aged from 16 to 48(mean:32 years). Twenty one patients had unilateral disease. Five patients had bilateral disease underwent staged bilateral free vascularized fibula grafts three months apart. Associated etiological factors included alcohol(9 patients), steroid(7 patients), and trauma(one patient). The condition was considered idiopathic in the remaining 9 patients. Radiologic staging by Ficat included stage 1 in one hip, stage II in 15 hips, stage III in 14 hips, and stage IV in one hip. A skin island flap was used for monitoring purpose for the grafted fibula. One monitoring, flap was necrotized due to vascular occlusion but the fibula bone graft was left in place to use as a nonvascularized bone graft. Average follow-up period was 21 months in 31 hips. Pain was relieved in 28 hips(93.3 percent) and aggravated in 2 hips(6.7 per cent). On radiographic evaluation, 26 hips(86.7 per cent) demonstrated excellent preservation of the femoral head contour. Progressive collapse of the femoral head (greater than 1-2 mm) occurred in 2 hips, i mm depression in one hip with stage III and 2 mm collapse in one hip with stage IV. In conclusion, the free vascularized fibula bone graft is an excellent treatment modality for preserving the femoral head and relieving symptoms in cases of the osteonecrosis of the femoral head.

Bone graft is an important procedure in craniomaxillofacial reconstruction and the success of reconstruction depends on the survival of the grafted bone. In this study, the survival of the membranous inlay bone graft on the mandibles of dogs was investigated with bone scan and histologic examination. The inlay bone graft, 1x2cm critical-sized bone, was completely separated from the lower border of the mandible of dogs and then refixed to the original site. Bone scan and histologic examination were done at 1,2,3 and 4 weeks postoperatively. The bone scan after 1 week showed radioisotope uptake on the margin of the grafted bone and the isotope count was 21% compared to the uptake of the normal bone. After 2 weeks, the radioisotope uptake in the grafted bone increased to 52% of normal bone uptake. After 3 and 4 weeks, the degree of isotope uptake was 111% and 124% respectively. Histological findings after 1 week showed the absence of osteoblastic activity and 6 viable blood vessels in one 200X magnified field, which was 25% compared to the vessels of the normal bone. After 2 weeks, osteoblastic activities were noted and the number of viable blood vessels totalled 15, which was 63% of the vessels of the normal bone. After 3 weeks, osteoblastic activities increased and the number of viable blood vessels totalled 21, which was 88% of the vessels of the normal bone. After 4 weeks, there were markedly increased osteoblastic activities with a total number of 23 vessels, which was 96% of the normal bone. In summary, the revascularization of the membranous inlay bone graft began from the first week after bone graft, and then it gradually increased. After 3 weeks, the revascularization had returned to a nearly normal value compared with the value of the near-by normal mandibular bone.

Ameloblastic fibrosarcoma is an extremely rare variety of odontogenic tumor. It has not previously been reported in Korea. The tumor is composed of benign odontogenic epithelium with a mesenchymal part which exhibits the histologic features of fibrosarcoma. We have reported a case of amloblastic fibrosarcoma of the mandible in a 26-year-old man with swelling of right mandible for 2 weeks. The tumor showed yellowish ill-demarcated ulcerating mass involving right premolar and molar area. Light microscopy revealed irregularly arranged strands and islands of odontogenic epithelium surrounded by abundant mesenchymal tissue with the feature of fibrosarcoma. The fibrosarcoma cells were strong positive on immunostain for vimentin and ameloblastic cells were weakly positive for cytokeratin. S-100 and CEA were negative in both epithelial and sarcoma cells. The sarcoma cells were corresponding to fibroblasts on the electron microscopy with abundancy of RER and mitochondria and covering of basal lamina. Two types of virus like particles were distributed in the cytoplasm and nuclei of sarcoma cells. We treated the patient with surgery and chemotherapy. The recovery was uneventful and the prognosis is under observation.

The 35 patients who have suffered from myositis ossificans were investigated for 11 years. They wereposttraumatic patients, They trauma was divided into 3 groups; spinal cord injury, direct injury(fracture) andmixed type involving both. We evaluated the age distribution, the frequency of myositis ossificans, predilectionsite, bilaterality and relation between predilection site and bilaterality to the type of trauma. The results areas follows; 1. The age distribution was highest in 4th decades(12 among 35 patients). 2. In regard to distributionof 35 patients, spinal cord injury were most common (15 cases, 43%), the fracture nextly common (14, 40%) and thenmixed type (6,17%). 3. Among 51 cases of myositis ossificans, the frequency was highest in spinal cord injury(25cases, 49%), next was fracture(14, 27%). 4. The correlation between predilection site of myositis ossificans andlevel of spinal cord injury, hip is the most frequent site in thoracic injury. 6. The bilaterality of myositisossificans is 39%(20 among 51 lesions).

To investigate the factors which affecting the cognitive function and depression of the 65 or more age group, the authors surveyed for the subjects in the region of Taejon and nearby Taejon area. 729 studied subjects were tested for cognitive function with MMSE and depression with GDS. The main results were followings; In the studied subjects, the rate of normal cognitive function was 56.8%, the rate of mildly impaired was 24.l% and the rate of severe impairment was 19.l%. The cognitive function level was closely related to the depression score. As the age increased, the cognitive function was more impaired. Sexual difference was also existed in the cognitive function level and the depression score. After adjusting the effect of age, the variables such as sex, marital status, education level, past job, instrumental ability of daily living, regular physical exercise, frequencies of going out the house, chest discomfort, visual and auditory disturbance, and dizziness had the significant relationship with cognitive function impairment. Among these variables instrumental ADL, age, visual disturbance, and sex showed statistical significance in the logistic regression model. In the multiple stepwise regression, the variables which had significant relationship to depression score were education level, frequencies of going out house, current job and house work activity, regular physical exercise, instrumental ADL, self-rated health and nutritional status, dizziness, visual disturbance, and chest pain. In conclusion, main characteristics which had close relationship to the cognitive function and depression symptoms in the studied subjects were physical function and self rated health status.

The authors studied the pattern of vascularization of the tensor fasciae latae muscle in 110 Korean cadavers using macroscopic dissection and radiographic methods. The location of the points in this study were expressed as XY coordination in reference to the line between ASIS (A) and lateral margin of the patella (B). The deep femoral artery was arised from XY coordination value X: 8.1 cm, Y: 5.5 cm. The length and external diameter of the deep femoral artery were 30.0 mm, and 5.6 mm, respectively. The most common pattern of the lateral circumflex femoral artery was from the deep femoral artery 81.4% (n: 176) and femoral artery 18.6% (n: 42). The lateral circumflex femoral artery was arised from XY coordination value X: 10.3+/-1.3 cm, Y: 4.6+/-0.8 cm and ended XY coordination value X: 10.5+/-2.3 cm, Y: 3.7+/-9.6 cm. Lateral circumflex femoral artery branched into ascending, transverse and descending branch. The length and external diameter of the lateral circumflex femoral artery was 21.2+/-12.9 mm, and 5.1+/-2.3 mm, respectively. The average number of branches, length and external diameter of pedicles to the tensor fasciae latae muscle were 3.9+/-3.5, 30.9+/-12.1 mm and 2.6+/-0.7 mm, respectively. The pedicle of the tensor fasciae latae muscle arised from XYcoordination X: 8.8+/-2.0cm, 1.8+/-0.9 cm and skin territory was 5x13 cm2 at 13 cm on the line AB. The pattern of distribution, arterial supply and territories of the tensor fasciae latae muscle obtained in this study will provide useful anatomical backgrounds for the free flap surgery.
