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.

Spinal fusion has performed for instability and anatomical reconstruction since 1985 by Barthe. Bone grafts and synthetic materials has been used for spinal fusion, but they have several limitations and complications. Recently a new synthetic polymer B.O.P.(Biocompatible Osteoconductive Polymer) was developed and it overcome the limitations of other materials. The B.O.P. showed no foreign body reaction and gave scaffolding for the osteoconduction and osteointegration. Authors operated 35 cases of spinal fusion with B.O.P. and the results and literature reviews were discussed.

Anterior interbody fusion has used for instability and anatomical reconstruction in various cervical diseases since 1958 by cloward. Bone grafts such as autograft, allograft, xenograft and synthetic materials were utilized in fusion as a graft material. But conventional fusion materials have problems including postoperative morbidity, transmission of diseases, foreign body reaction, collapse, prolongation of operation time. A new synthetic material, Biocompatible Osteoconductive Polymer(B.O.P) is developed and it was useful for cervical anterior interbody fusion as a substitute for other fusion materials.

Takayasu's arteritis is a chronic vasculitic disease of the aorta, its major branches and the pulmonary arteries, resulting in stenosing, occlusive or aneurysmal lesion. While the precise etiology of Takayasu's disease is unknown, an autoimmune mechanism or active tuberculous inflammation have been suggested. It is more common in young oriental women but has a rare incidence in children. We experienced a case of Takayasu arteritis type IV in an 8years old girl. The diagnosis was made by physial examination and digital substraction aortography(DSA) which showed narrowing of left common carotid artery, right subclavin artery and left renal artery. The perfusion defect at posterior segment of right upper lobe was noted in lung perfusion scan. Medical treatment and percutaneous transluminal angioplasty(PTA) were performed. In addition to case report, a brief review of literature was added.

BACKGROUND: Generalized aggressive periodontitis (GAP) is a destructive periodontal disease that can develop in young age. Only a few cases of full mouth rehabilitation, using dental implants, have been reported in a patient with aggressive periodontitis. CASE DESCRIPTION: This clinical report describes the treatment procedures and results of full mouth rehabilitation in a patient with aggressive periodontitis. After all teeth were extracted, 6 implants were placed in the maxilla and mandible, respectively. Fixed detachable implant prostheses were made. The patient was satisfied with the final results. She was followed for 10 months postloading. CLINICAL IMPLICATION: For a long-term success, continuous maintenance care is critical, as the contributing factors of the disease (such as immune factors or periodontal pathogens) may not be controlled adequately.

STUDY DESIGN: This study assessed the final functional results after treatment of thoracolumbar burst fractures and compared the relationship between the results and the parameters of reduction and state of the fractures. OBJECTIVES: To define prognostic factors affecting the final results and to present some precautions to minimize the treatment failure. SUMMARY OF LITERATURE REVIEW: In the treatment of the thoracolumbar burst fractures in which flexion loads are predominant, the sagittal contour is crucial to achieve permanent pain-free stability, but definitive therapeutic guidelines have remained a controversal topic. MATERIALS AND METHODS: We reviewed 37 thoracolumbar burst fractures with an average follow up period of 1.8 years: group 1 consisting of 20 cases treated conservatively and group 2 consisting of 17 cases treated surgically with posterior instrumentation. Finally functional results were analysed with the Denis'pain and work scores, and were compared between groups on anterior body height and local kyphosis. RESULTS: A satisfactory pain score less than or equal to P3 was in 15(75%) in group 1 and 15(88.2%) in group 2(p>0.05), but satisfactory work score less than or equal to W3 was in 12(60%) in group 1 and in 14(82.4%) in group 2(p<0.05). But, some loss of body height and local kyphosis in group 1 was not reversely related with functional outcomes. Eight cases in group 1 showing unsatisfactory result in work scores were analyzed as 4 osteoporosis(Jikei grade I, II/III), 3 associated compression fracture of the contiguous vertebra and one combined osteoporosis and compression fracture, showing significant loss of vertebral height and increase of kyphosis(p<0.01). CONCLUSIONS: Functional results of group 1 showing loss of vertebral height less than 50% and increased kyphosis less than 200 were comparable to those of group 2. The osteoporosis and associated compression fracture of adjacent vertebra were the risk group to develop posttraumatic kyphosis and might be added to the surgical indication of the thoracolumbar burst fractures.

Fetal echocardiography is used by means of decleration of fetal cardiac anaztomy, to estabilish the diagnosis of congenital heart disease in utero. We attemped fetal echocardiography to ninty three pregnant women after intra uterine period 24 weeks, and estimated cardiac circumference, cardiac axis, pulmonary atery root diameter, arortic root diameter, diameter of inferior vena cava, diameter of superior ve studied how these estimates associate with following gestational na cava, and fractional shortening of ventricles. We ages. Cardiac axis was on the average 37.28 degree and cardiac apex was located in anterior left side of chest area. Aortic root diameter was 0.227 GA-0.043mm (GA=gestational age) at systolic phase, 0.203 GA+0.421mm at diastolic phase. Pulmonaly root diameter was 0.271 GA-0.029mm at systolic phase, 0.251 GA-0.067mm at diastolic phase. Thoracic aorta diameter was 0.195 GA+0.109mm at systolic phase, 0.198 GA+0.794mm at diastolic phase. Fractional shortening was 0.24 (1 Standard Deviation=0.11) in right ventricle, 0.23(1 SD=0.154) at left ventricle, and so ratio of right and left ventricle was 1.04(1 SD=0.51). Once normal fetal cardiac anatomy is understood, structural defects and/or alternation of function can be evaluated antenatally.

Seidel nail provides more advantages for treatment of humeral shaft fracture than other treatment modalities. It enables patients to get high bone union rate, makes surgical technigne less invasive, and allows early mobilization mobilization so that the patients is subjected to more comfortable treatment. But, Seidel nail is apt to injure the rotator cuff and has relatively weak holding power of distal fragment of fracture so that it may result in distraction and rotatory instability, and make nonunion and impaired shoulder function. Thus, in order to the functional and radiological results, complications and technical problems, we evaluated the efficacy of Seidel nail in treatment of 20 cases of hurneral shaft fractures from March l994 to March 1996, retrospectively. The results were as follows. 1. 18 cases(90%) achieved radiological union. 2. The time of union was 12.5 weeks in average. 3. 17 cases achieved satisfactory results according to Neers functional score. 4. The complications included proximal protrusion of nail from the entry site(10%), fracture of greater tuberosity of proximal humerus(5%), loosening of distal spreading screw(10%), and nonunion( l 0%). In conclusion, Seidel nailing is one of good treatment modalities for humeral shaft fracture, but skillful operative technique is needed to obtain the satisfactory functional result. And also, it is necessory to modify the distal locking system of Seidel nail to reinforce the rotational stahility of the fracture site.
