Between Jan. 1976 and May 1987, Sixteen supracondylar fractures of the femur were treated by interlocking nailing. Of the 16 cases, 7 cases were intercondylar, 12 cases were segmental fractures of the femur, 4 cases were open fractures in the type of wound. 1. The simple supracondylar fracture involving the distal 9cm of the femur can be treated by interlocking nailing which makes firm fixation and allows early ambulation. 2. If the supracondylar fracture is accompanied with intercondylar fracture, careful reduction and transcondylar fixation by means of tibial bolt or cancellous screws are essential before the insertion of the nail. 3. The shape of the bent nail must be depended on the type of the fracture. If the nail is to be inserted into the anterolateral aspect of the distal fragment, the degree of bending of the nail is 400cm, and posteromedial is 110cm in radius. 4. The authors made several sagittal holes the at dorsum of the nail. So the screw can be easily inserted to the nail perpendicularly or obliquely, when the insertion of the screw through the transverse holes is difficult. 5. Of the 15 cases treated by interlocking nailing, 5 cases were excellent, 4 cases were good, 2 cases were fair, 4 cases were failure by schatzker assessment.

The intramedullary nailing is a good method of treatment in femur shaft fracture but it is not available in some fracture pattern or fracture level. And it is very difficult with conventional Kiintscher nailing to prevent torsional stress and fix rigidly in unstable fracture of the femur shaft. The unstable fracture by comminuted fracture or segmental fracture, nonunion and pathologic fracture needed the rigid fixation. Interlocking Kuntscher IM nailing can provide antitorsional stability, good axial alignment and prevent shortening of the fracture site, also allow early ambulation and joint exercise. We analysed 51 patients 52 cases of interlocking Kiintscher IM nailing from May 1981 to March 1988. The interlocking Kuntscher IM nailing prevents the rotational and axial roading. The interocking Kuntscher IM nailing has expanded its application in fracture pattern and fracture site. The interlocking IM nailing provides rigid fixation in severe comminuted fracture. segmental fracture, long spiral fracture, and other several unstable fractures and eliminates splinting or external supports, so it is possible doing early joint exercise. The interlocking Kuntscher IM nailing was also considered best internal fixation method in pathologic fracture or sever osteoporosis. The static interlocking for rigid fixation and the dynamic interlocking method for axial compression to fracture site during weight bearing can be adapted appropriately to fracture pattern. Radiation hazard during the interlocking nailing is not considerable.

Many patients whose chief complaint is headache caused by accident such as traffic accident, falling, or assaults visit to emergency center. Majority of these patients has mild or moderate symptoms, and there is no need to treat surgically. However, the fact that head injury can cause SIADH(syndrome of inappropriate secretion of antidiuretic hormone) is likely to be overseen. Acute hyponatremia might have been associated with death or permanent brain damage. Hyponatremia is best handled by early recognition and correction of a downward trend in the serum sodium. Unfortunately, this is often difficult in the head-injured patient, where hyponatremia may occur fairly rapidly and is confused by symptoms of head injury. when moderate to severe hyponatremia occurs, it is important to determine its etiology and expeditiously initiate corrective action. There has not been any reported case of the occurrence of symptomatic SIADH after mild head injury in Korea yet. The authors report the experience of three cases of symptomatic SIADH after mild head injury with review of the literatures.

Hemoptysis is quite common in primary pulmonary disease, including tyberculosis and carcinoma, as well as in congenital heart disease. Rescently the authors had experienced a case of massive hemoptysis soon after extracorporeal circulation during open heart surgery. The patient had been diagnosed as pulmonary tuberculosis and triology of Fallot. After surgical procedure for pulomonary stenosis and A.S.D, massive hemoptysis occurred abruptly through the endotracheal tube and B.P. took a sudden fall by 40 Torr/systolic pressure. Bleeding source was proved to be on the left upper lobe. So left upper lobetomy had to be performed to control this massive hemoptysis.

This is a ease report of intraluminal partial obatructian of an endotracheal tube after cuff ballooing, a complication of a malfunctioned endotracheal tube, This 18 year old female patient with herniated intervertebral disc of L4-5 was anesthetized for archotomy and removal of disc. Aneethesia was maintained with N2O-O2-halothanepancuronium after endotracheal intubation with a Murphy tube. (Porges-Latex-tube No. 7), manufactured in France. A few minutes later, airway obstruction signs such as sudden hypertension, tachycardia, resistance of the researvoir bag in inspiration, and delayed filling time of the reservoir bag in expiration appeared. We suspected kinking of the tube, tubal obstruction from secretions, bronchospasm etc, but we could not find the exact cause of airway obstruction in spite of detailed checking. After recovery of the patient from anesthesia we checked the extubated tube. There was intraluminal partial obstruction of the endotracheal tube according to increase of intracuff volume and pressure because of the thin walled, flexible tube and diffusion of N2O into the cuff. After extubation the patient returned to normal. We surmmerized this case and also reviewed with the literature.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

A total of 36 typical Krukenberg tumors of the ovary was obtained from the pathology file of the Department of Pathology, College of Medicine, Seoul National University during a period of 17 years from January 1968 to December 1984. By definition, all were characterized by the presence of mucin containg signet ring cells within the cellular, nonneoplastic ovarian stroma. The clinico-pathologic characteristics of 36 Krukenberg tumors were as follow: The Krukenberg tumors accounted for 16.3% of all ovarian malignancies. The age of the patient at the time of diagnosis of the Krukenberg tumor ranged from 28 to 69 years with an average of 43 years. A primary carcinoma of stomach (31 cases) of colon (1 case) was found in 32 (88.9%) of 36 patients. The primary carcinomas was not detected in four cases, and autopsy was not performed in any case. In 22 cases the primary carcinomas had been diagnosed before ovarian tumors were found. The ovarian and the primary carcinomas were identified synchronously in 6 cases, while in 8 cases the primary carcinomas were not discovered until after the ovarian tumors had been treated. The gross diameter of the ovarian tumor ranged from 1.5cm to 28cm with an average of 10.3cm. The largest weighed 4,550gm. The Krukenberg tumors typically formed rounded or reniform, solid mass that were coarsely lobulated or bosselated. The cut surface was yellow white and associated frequently with nodular, myxoid or gelatinous area and cystic changes of various size. Both ovaries were involved in 29(80.6%) of the cases and one ovary in 7(19.4%). Krukenberg tumors classified into the three major types on the basis of the characteristic morphologic patterns of signet ring cells. The first type was classic Krukenberg tumor(28 cases) represented by predominent components of typical signet ring cells. The second type was tubular Krukenberg tumor(5 cases) characterized by tubular structures resembling a Sertoli-Leydig cell tumor. The third type was re tiform Krukenberg tumor (3 cases) characterized by an irregular network of elongated, often slitlike tubules and cysts, which resembled the rete testis.

The degenerative arthritis following total menisectomy has led to consideration of the need for meniscal transplantation, this study evaluates the morphologic and histologic changes fol lowing fresh meniscal autograft and allograft in therabbits. Transplantation of the medial meniscus was carried out in two groups of 32 rabbits(autograft group=16 rabbits, allograft group=16 rabbits). The morphological and histological changes of the transplanted auto-and allografted menisci and the articular cartilage of the medial femoral and tibial condyle were observed at 2,4,6,8,10,12,22,28 weeks postoperatively. There were no significant differences between auto and allograft groups in gross appearance. Histologically, the fibrous adhesion was noted between grafted meniscus and joint capsule 2 weeks after operation, but complete healing was seen at the suture sites without rejection phenomenon at 6 weeks in both groups. There were prominent inflammatory reactions such as lymphocytes and inflammatory cells infiltration during early postoperative stages(2,4 weeks) only in the allograft group, and more prominent fibrotic reactions in the allograft group than auto-graft group. The results of this study suggest that meniscal allografts are able to adapt to the host tissues, survive within the joint environment, and provide a functional replacement for the removed meniscus, but further studies for graft-host immune response and a method to take the maintenance and deposits of graft must be needed to perform the meniscal allograft in human.

We studied 75 cases of conventional Kuntscher intramedullary nailing and 52 cases of interlocking intramedullary nailing from July 1980 to October 1988 for femur shaft fractures. The conventional Kuntscher intramedullary nailing was used for fresh fracture and the interlocking intramedullary nailing was used not only fresh fracture, but also unstable fracture, nonunion and pathologic fracture. The conventional Kuntscher intramedullary nailing was frequently used in middle one-third level, but the interlocking intramedullary nailing could be applied widely from subtrochanteric area to supracondylar level in femur. The average operation time in patient who had no associated injury was 3.6 hours in conventional Kuntscher intramedullary nailing and 3.25 hours in interlocking intramedullary nailing. Time period for union was much less in interlocking intramedullary nailing than conventional Kuntscher intramedullary nailing. Some kinds of immobilization was needed shortly in conventional Kuntscher intramedullary nailing but immediate postoperative ambulation was possible in interlocking intramedullary nailing. Interlocking intramedullary nailing can prevent the angulation, shortening and trochanteric bursitis due to migration of the intramedullary nail.
