PURPOSE: In order to assess the incidence and radiologic findings of herniation pit of the femur neck in Korean. IVlaterials and Methods:In 152 macerated femurs of 88 cadavers, and randomly selected 115 hips of 70 patients, the presence of herniation pit was determi ned by using fluoroscopy and radiography. It was then examined by CT for inspection of overlying surface and its opening was confirmed by inserting thin steal wire under the fluoroscopic guidance. RESULTS: Seventeen herniation pits in 15 macerated femurs of 13 cadavers were noted. (14.8%, 13/88). Two of 13 individuals showed bilaterality. All lesions were found only in males. Six herniation pit in 6 femurs of 6 patients (8.6%, 6/70) were also noted. All lesions were on anterosuperior aspect of. femur neck. Plain radiographs of macerated femurs revealed well marginated and thin sclerosis in 15 lesions. Of all 23 lesions, CTshowed cortical breakdown in 3, and overlying cortical thickening in 8. In 15 macerated femurs, roughed area of cortex was found in anterosuperior aspect of femur in all cases, and tiny openings(diameter less than 1 mm) related to cystic lesions were confirmed in 9 lesions. CONCLUSION: The incidence of herniation pits was 14.8% in 88 cadaver, and 8.6% in 70 patients. All were males.

In open wounds of the hand that have exposed bone or tendons, management may be difficult. Compared with conventional cutaneous pedicle flaps, the fascial radial flap transfer has several advantages : (1) one operation is required by one operating team reliably and easy to perform, (2) the appearance is not bulky, (3) the donor area is closed primarily, and (4) the hand is free for early motion of the shoulder and the elbow. One potential disadvantage is the permanent loss of the contribution of the radial artery to the circulation of the hand. One case of the fascial radial flap transfer was performed at the Department of Orthopaedic Surgery of Hanyang University Hospital, and satisfactory result was obtained.

Angiography has been playing important roles in diagnosis and treatment in the field of orthopaedic surgery. Conventional angiography is the most reliable and widely used method in diagnosis of peripheral arterial disease. But the clinical use of the conventional angiography has been limited by the risk of possible complications and time-consuming procedures. Radionuclide sngiography is rapidly performed, rapidly interpretable and time-saving procedure for the visualization of arterial tree prior to vascular intervention in the critically ill patient. We have analyzed and compared the 22 cases who had taken radionuclide angiography and conventional angiography simultaneously from November, 1986 to August, 1987 in Department of Orthopaedic Surgery, Hanysng University Hospital. The results were as follow 1. Radionuclide angiography is simple, non-invasive, accurste, reproducible method. It eliminstes the discomfort and morbidity of conventional angiography and can be done on an outpatient basis at a much lower cost. It is useful in the patients who may be allergic to the contrast medium. 2. In cases of arterial occlusion, radionuclide angiogrpahy is also useful in the evsluation of obstruction of major artery and can be substituted for conventionsl angiography. 3. For the purpose of evaluation of success in the cases of vascular reconstruction, radionuclide angiogrphy also demonstrate the vasculsr blood flow without any risk. 4. Although rsdionuclide angiography has limitstion in snatomic detsil, it could be psrtially substituted for conventionsl angiography in the diagnosis of vascular anomalies or tumors.

Fourty one cases of open fractures of tibial shaft complicated with varying degrees of soft tissue injuries were trested by one-plane unilateral external fixation with AO fixator. In seventeen csses among them, interfragmental lag screw fixation was applied in addition, for more rigidity and stability of the fixation. All of thern were followed up at least for one year and we obtained the following results. 1. Rigid stable external fixation provided by additional minimum internal fixation may not increase the rate of infection but rather enhance prompt primary bone healing. 2. One-plane unilatersl external fixation may facilitate good access to the wound for subsepuent reconstructive procedures, and enhance pain-free early full range of joint motion, thus promote early bone union. 3. Comparing with bilsteral fixation, there wss almost no difference in the union time of the fracture even with one-plsne unilatersl fixation.

OBJECTIVE: The purpose of this study was to evaluate the clinical course of discordant fetal growth and perinatal outcome in relation to dichorionic and monochorionic twin for different degrees of birth weight difference. METHODS: Between Jan. 1992 and Dec, 1997, 154 twin pairs were born at Yonsei medical center and there were 36 pairs of twins which had 20% or more birth weight difference. The placental examination were performed routinely on all multiple births and 13 pairs of dichorionic twins and 23 pairs of monochorionic twins were consisted of the study population. These twin pairs were divided into three groups based on birth weight difference: 20-29%(as group A), 30-39%(as group B), and 40% or more(as group C). Gestational age, birth weight, gender and perinatal outcomes were observed for each twin pairs. RESULTS: The perinatal death in the monochorionic twin pairs showed 9(34.6%) as group A, 4(50%) as group B, and 5(41,7%) as group C and in the dichorionic twin paus 1(10.0%) as youp A, 0 as group B and 5(62.5%) as group C. Up to 40% of birth weight difference, dichorionic twin pairs showed good perinatal outcomes compared with monochorionic twin pairs but over 40% or more of birth weight diffaence, however there were no significant difference of perinatal outcomes by chorionicity. In the monochorionic twin pairs, the cause of perinatal death showed 3 cases of prematurity, 2 cases of congenital anomalies and 2 cases of IIOC and 2 cases of cord lesions in group A whenas in the group B and C 3 cases of prematurity and 6 cases of congenital anomalies. In the dichorionic twin pairs, different-sex twin pairs showed no perinatal death in all three groups but in same-sex twin pairs there were 6 perinatal deaths. CONCLUSION: More recent improved fetal ultrasonographic surveillance such as determination of chorionicity, identification of fetal sex and evaluation of fetal anomalies help to make a clinical decision in growth discordant twin up to 40% of weight difference each other.
