We have experienced 11 cases of large bony defect that were treated using microsurgery since 1981. Free vascularized bone transplantation was performed in 8 of them, vascularized bone transposition in 2 cases, and free vascularized joint transplantation in the remaining 1 case. The causes of the large bony defect were primary bone tumor (4 cases), congenital pseudoarthrosis (3 cases), open comminuted fracture (2 cases), sequela of osteomyelitis (1 case), and post-traumatic ankylosis of PIP joint of second finger (1 case). As a donor, fibula was used in 8 cases, iliac crest in 1 case, rib in 1 case and in the remaining 1 case, the second M-P joint of foot was transplanted. In 9 of 11 cases, successful result was obtained and 2 cases were failed because of vascular damage following tibial lengthening in one case and infection on the grafted area in the other one. From the above data and review of articles, following conclusions were obtained. 1. Fibula is thought to be the most appropriate donor for the large bony defect in the extremity, especially in lower extremity, but the donor site must be determined according to the anatomical and physilogical condition of the patient. 2. After mechanical lengthening of the extremity, it is recommened to perform the microvascular surgery after sufficient time for the recovery of vascular damage. But further studies are required for the identification of the change in the vascular tissue following stretching and its recovery time. 3. Progression of the ossification in the epiphysis of transplanted iliac crest was observed and this finding proposed us the idea that the epiphyseal plate injury or leg length discrepancy will be able to be treated with free vascularized epiphyseal plate transplantation and the reconstruction of the destroyed joint of growing children will be possible using free vascularized joint transplantation. 4. As the technique become more popular, the free vascularized bone transplantation is being used for the reconstruction of the extremity more frequently, but it seems to be wise to restrict its indication to cases which are impossible to be treated with more simple methods such as vascularized bone transposition or pedicled bone graft.

In patients disabled by severe rheumatoid and degenerative arthritis of both knees, bilateral total knee arthroplasty(TKA) afforded much functional improvement in pain relief and function. Postoperative results of bilateral TKA was described as being similiar to those observed among patients with single joint replacement. The purpose of this study is to evaluate the etiology and postoperative result of bilateral TKA performed on 32 knees in 16 patients at Department of Orthopedic Surgery, Seoul National University Hospital from Mar. 1985 to Oct. 1988. In our series, there were 15 females and only 1 male, their mean age was 53 years. Duration of follow up was ranged from 1 to 4 years and 5 months being average 1 year and 6 months. The results were as follow. 1. Cheif complaints were pain in 18 cases(100%) and difficulty in walking in 15 cases(82%). 2. Preoperative etiology was rheumatoid arthritis in 11 cases and degenerative arthritis in 7 cases. 3. Knee joint function by HSS(Hospital for Special Surgery) knee rating score was increased from 44.6 points preoperatively to 81.2 points postoperatively. 4. The tibiofemoral angle was changed from 1.4 degree varus to 4 degree valgus. 5. The prothesis type used were PFG(Press Fit Condylar) in 22 knees, Miller-Galante in 8 knees, AMK in 3 knees, PCA in 2 knees and unicompartmental type in 1 knee. 6. Complication were 1 case of knee fusion due to concomittant tuberculous arthritis and mild joint effusion in 6 knees. 7. Bilateral one-stage arthroplasty may be considered as an alternative procedure.

Cardiovascular disease is the most important cause of unexpected sudden death. Although ischemic heart disease by coronary atherosclerosis is the most common cause of sudden cardiac death, other diseases such as cardiomyopathy, congenital heart disease, valvular heart disease and rarely myocarditis can produce sudden cardiac death. Myocarditis is an inflammatory process of the myocardium characterized by an interstitial inflammatory infiltrate and an injury to myocytes adjacent to the inflammatory cells. The clinical expression of myocarditis ranges from the asymptomatic state to fulminant fatal congestive heart failure. Because myocardial involvement is subclinical in most acute infectious disease, the majority of patients have no specific complaints referable to the cardiovascular system. It is possible that it causes a medicolegal problems in case of sudden death. Therefore, author reviewed the clinical and pathological findings of 18 myocarditis autopsy cases. The victims 'age was varied 4-month-59-year olds. 5 (28%) were male and 13 (72%) were female. 15 cases received medical treatment due to clinical symptoms(URI symptoms: 2 cases, tonsillitis and tonsillar abcess: 3 cases, GI symptoms: 5 cases, URI & GI symptoms: 3 cases, pneumonia: 1 case, operation due to ovarian tumor: 1 case) and were associated with medicolegal problem. By the results of this study, important gross findings were pericardial effusions, characteristic cardiomegaly, and pulmonary edema.

M-mode echocardiograms were recorded in 268 apparently healthy young male adults and the mitral valve motion during systole was analyzed. In 149 cases( 55.6%) out of 268 the predominant echo of mitral valve closure(CD line) was recorded as smooth line moving slowly anteriorly, in 48 cases(17.9%) the CD line showed an abrupt transient posterior motion during early systole, in 24 cases(9.0%) there were multiple additional echoes posterior to the CD line, 17 cases(6.3%) the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating less than 2 mm from a drawn CD line, and 10 cases(3.7%) as curvilinear and anteriorly convex echo deviating from a drawn CD line. In the remaining 20 cases(7.5%), the mitral valve closure was recorded as pansystolic anteriorly concave echo deviating more than 2 mm from a drawn CD line, which was categorized to have mitral valve prolapse in the current study. However, there were no significant differneces in various echocardiographic dimensions of the heart and the aorta between those with and without mitral valve prolapse.

Two autopsy cases of asphyxia due to oxygen deficiency are reported. The first case is that a 38-year-old man died in a storehouse. Many pears were stored in a storehouse and the its atmosphere was strictly controlled. The second case is that a 42-year-old man died in the boiler room of a fishing ship. Much amount of Freon gas escaped due to a defect of the refrigerator in the boiler room. The victim entered the boiler room because he repaired the refrigerator. But, the victim died when he entered the boiler room immediately. In this article, the autopsy findings and the contents of the investigation of scene of two cases are described.

Postmortem body inspection at scene and examination of the scene of death are very important in determination of the suspected cause of death, manner of death and interpretation of events leading death, nature of injuries, time of death etc. Actually these works must be performed by well-experienced forensic pathologists. And forensic pathologists should visit the scene of death before the body is removed. In Korea, attendance at scene of death by forensic pathologists is not performed effectively due to low faculty of forensic pathologists and the problem of medicolegal investigation system. But we try to overcome these problems and begin to the work of postmortem body inspection at scene and examination of the scene of body in area of Daejeon Metropolitan city since March, 2003. In this report we recommend the guideline for postmortem body inspection at scene on forensic aspects. We believe that sharing the experience and knowledge about scene investigation including postmortem body inspection at scene and examination of the scene of death is very important to improve and change the environment of medicolegal investigation system in the future.

Pontine hematoma would be diagnosed and made its follow-up readily as the extent of hematoma could be clearly defined since the CT scan was available, especially with MRI in recent. Authors attemped to analyse 20 cases of pontine hematoma clinically, considering factors of influence their prognosis, admitted in Inha hospital from March 1989 to February 1992. Classification of pontine hematoma was made out according to the findings of brain CT scan taken on admission:2 cases of Type T1 to the hematoma localized in the tegmentum unilaterally, 1 case of Type T to those in the tegmentum bilaterally with some extent into the 4th ventricle, 12 in Type T to those in the tegmentum, midbrain and mostly the 4th ventricle, and 5 in Type B to those in the basis pontis mainly with tegmentum and midbrain. Of 219 spontaneous intracerebral hematoma, pontine hematoma was 9.1%. 17 hypertension and 11 previous CVA episodes including 7 cerebral infarction and 4 ICH were endountered. Age distribution was 50% in 6th decade and male to female ratio was 3:2. On admission 14 cases were under 6 in Glasgow coma scale, 6 small reactive pupils and 11 ocular bobbing. Particularly, nuclear facial paralysis was 14 in initial bilateral type, of which 7 dead within 10 days, 5 fixed in left facial paralysis and 1 case into right paralysis later. Four surgical interventions were 1 simple EVD, 1 Urokinase irrigation through EVD, 1 steretactic aspiration and 1 direct hematoma removal. Prognosis was related to various factos:GCS on entry, volume and classification of hematoma, in addition to laterality of nuclear facial paralysis. Clinical course was better in cases over 10 GCS on entry, volume and classification of hematoma, in addition to laterality of nuclear facial paralysis. Clinical course was better in cases over 10 GCS, Type T1 and T2, and unilateral facial paralysis in which the ratio of left to right was 2:1, while it was very poor in patients who were GCS below 6, Type B and bilateral facial paralysis. On the contrary, 7 of 20 cases were dead within 10 days, 13 patients alive for more 3 months after the hemorrhage were observed with fixed facial paralysis in nuclear type, 1 ilateral, 4 right, and 8 left side. It is suggested and requested for further careful follow-up that the hemorrhage may occur from the border zone between paramedian, short and long circumferential arteries supplying transection area of the pons unilaterally, near on around the facial nucleus, more frequent in left side.

Thirty four patients with diffuse axonal injury, defined as post-traumatic coma for over 24 hours with Glasgow Coma Scale(GCS) score of 8 or less following nonsurgical resuscitation, admitted to Inha Hospital from January to December 1991, were studied in order to identify clinical analysis. The aim of this study was to find out the effects of barbiturates or other intensive therapy or head elevation on the intracranial pressure(ICP), arteriovenous oxygen difference(AVDO2) and outcome. The results were as follows; The ratio of male to female was about 6 to 1. 2) In clinical signs at the emergency room, abnormal pupil size was shown 17 cases(61%) under 8-5 on the GCS, but all cases under 5 on the GCS showed abnormal pupil size. 3) Ventricular compression was shown in 29 cases(85%), 17 cases(50%) was showed the ventricular compression & cisternal obliteration. 4) Post-traumatic cerebral infarction was developed 59% of DAI and occurred in 88% of ventricular compression and cisternal obliteration. 5) On admission, above 5 ml/100 ml in AVDO2 was developed in 32 cases(94%) under 8 on the GCS, but in all cases under 5 on the GCS. Recording of ICP showed above 20 mmHg in 15 cases(44%). On coagulopathy, our cases showed that decrease of platelet was involved in 5 cases(15%), prothrombin time(PT) prolongation in 11 cases(32%), activated partial thromboplastin time(APTT) in 4 cases, fibrinogen in 5 cases. 6) The mean ICP was slightly lower when the patient's head was elevated at 30 degree than at 0 degree. The mean ICP was moderately lower when the patients were taken barbiturates therapy. ICP tends to increase from the 1st to 3rd day after injury. 7) The mean AVDO2 was significantly lower when the patients were taken barbiturates therapy, especially at the 1st day. 8) On the relation between Glasgow Outcome Scale(GOS) and Neurological grading(NG), GOS IV was developed in 8 cases(NG score 3-6), GOS III in 5 cases(NG score 7-9), GOS II in 2 cases(NG score 10). Total mortality rate was 56%.

A simplified method of the cardiac conduction system (CCS) is evaluated by the study of 73 forensic cases. The sinoatrial node were observed in all cases (100.0%), atrioventricular node in 70 cases (95.9%) and penetrating bundle (His bundle) in 70 cases (95.9%). We divided the cases into three groups as the group of cardiac death (25 cases), non-cardiac death (24cases) and sudden unexpected death but undeterminable cause of death (24 cases) diagnosed after routine autopsy including routine cardiac examination and toxicological analysis and compared the type and incidence of CCS lesions in each groups. Narrowing of the sinoatrial (SA) or atrioventricular (AV) artery by fibromuscular hyperplasia (FMH) and fatty infiltration in SA or AV node were identified in all groups, lymphocytic infiltration in SA or AN node in cardiac and non-cardiac death group, hemorrhage and fibrosis of SA or AV node were identified in cardiac death group. FMH of the artery of SA or AN node occured more commonly in undeterminable cause of death group (45.1%) than in cardiac (16.0%) and non-cardiac group (20.8%) and severe narrowing (> or =75%) of the artery of SA or AV node was only present in undeterminable cause of death group (29.2%). The results led to the conclusion that this simple technique is very useful in detection of major abnor-malities of CCS with minimal effort and examination of the CCS in death which the routine autopsy and drug screen fail to provide a cause of death can yield a cause of death in a significant percentage of cases.

We reviewed forensic autopsies and scene examinations performed at Central District of National Institute of Scientific Investigation, requested by every kinds of law enforcement agencies in Chung-cheong area of Korea during the year of 2003, and analysed the data of forensic autopsies and scene examinations according to the cause of death and the manner of death. The results are as follows ; 1. Scene investigation on the spot was performed in 220 cases ; Among these cases, 161 cases (73.2%) were unnatural deaths and the most common cause of death was trauma (61 cases). Autopy was per-formed in 93 cases (42.3%). 2. The total number of forensic autopsy were 685 cases (452 males and 233 females). The number of the forties (215 cases) and the thirties (124 cases) occupied almost half (49.5%) of all cases of autopsy. 3. Unnatural deaths were 434 cases (63.3%), natural 204 cases (29.8%), and the unknown 47 cases (6.9%). In 434 cases of unnatural deaths, suicide was 84 cases (19.3%), homicide 115 cases (26.5%), acci-dent 186 cases (42.9%), and the undetermined 49 cases (11.3%). Homicide occupied 43.7% of trauma, 77.1% of blunt force injury excluding traffic and fall down injury, and 97.7% of sharp force injury. The homicide rate in asphyxia was 35.0%. It showed only 1 cases (1.9%) of homicide in poisoning. 4. In 434 cases of unnatural deaths, traumatic deaths were 229 cases (52.8%). Blunt trauma was 70 cases (30.6%) and the leading cause of death in traumatic death. Of remaining 205 cases of unnatural deaths, there were 52 cases (12.0%) of poisonings, 51 cases (11.8%) of thermal injuries, 41 cases (9.4%) of drowning, 40 cases (9.2%) of asphyxia, 19 cases (4.4%) of medical procedures, and 2 cases (0.5%) of electrocution. 5. Among 204 natural deaths, cardiovascular diseases were 106 cases (52.0%) and the leading cause of death in natural deaths. 36 cases (17.6%) of diseases involving vascular system were followed. 6. Child deaths under the age of 10 were 32 cases. Among these cases, unnatural deaths were 14 cases (43.8%) and most of them were accident.
