In transtrochanteric rotational osteotomy to treat osteonecrosis of the femoral head, the necrotic superior anterior femoral head is rotated anteriorly around the longitudinal neck axis so that the weight bearing force is transferred to the intact posterior surface. The ratio of transposed intact articular surface of the femoral head to the weight-bearing surface of the acetabulum on postoperative anteroposterior view of the hip roentgenograph is the most important indicator of the prognosis. During the period from December 1992 to June 1994, we treated 31 hips in 28 patients who were indicated for the anterior rotational osteotomy among the patients of osteoncrosis of the femoral head. Among the patients, male were 27 and female was one. Age distribution was from 13 to 62 years old and mean age was 44.3. According to the Ficat and Arlet classification, II A was most in number as 16 II B was 7 and III was 8. As their etiolgic factors, alcohol was most in number as 18, steroid was 3, idiopathic was 5 and trauma was 2. The mean rate of the intact area of the posterior part of the femoral head to the total articular surface on the preoperative lateral view of the hip roentgenograph was 41.8%. The mean ratio of transposed intact articular surface of the femoral head to the weight bearing surface of the acetabulum was 53.8% Fixation devices were screws or dynamic hip screw.

The usefulness of hyperthermia for cancer therapy has been established. The purpose of the present investigation was to access feasibility of heating normal lung and the temperature and power requirement were compared with that for liver as solid organ in rabbits by using radiofrequent heating machine. In this study, 20 rabbits were divided into 2 groups according to the heating site and the method of temperature measurement ; in group I : lung heating and temperature measuring in skin, esophagus and lung parenchyme ; in group ll : liver heating and temperature measuring in skin and liver parenchyme. The results were as follows ; 1) When the maximum temperature was almost same in lung heating group and liver heating group, the power for liver heating was lesser required than the power for lung heating (p<0.05). 2) The temperature of esophagus for the measurement of mediastinum temperature was 1.1+/-0.9 degrees C higher than the temperature of lung parenchyme (p<0.05). Therefore the above findings suggest lung, air containing organ, is well heated as same as liver, solid organ. So more active trials of lung heating in the lung cancer must be likely considered. But whets the lung is heated, the esophageal temperature is higher than lung parenchyme, so the mediastinum damage must be considered seriously.

Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

The possible complications after parotidectomy are facial nerve palsy, Frey's syndrome, sialocele, salivary fistula, hematoma infection, and flap necrosis. Postoperative sialocele and salivary fistula are relatively uncommon and the management varies. We experienced a rare postoperative complication of excessive and prolonged drainage of saliva after superficial parotidectomy and removal of an necessary parotid gland tumor. The patient could be treated successfully with conservative management such as compressive dressing, restriction of oral intake of irritant food, maintenance of oral hygiene and the use of amitriptyline(antidepressant).

In this study, in order to obtain physiologic synthesis of testosterone in primary or secondary gonadal insufficiency by Leydig cells transplantation, newborn rat testis tissues were transplantated in castrated male rat. The rats were castrated about 5-6 weeks after birth and were observed for 10 days. At this time, testes were removed from a one-day-old rat and these were transplanted onto the bilateral renal subcapsular lesions of the castrated rats under an operative microscope. Of the 27 rats that were castrated, testis transplantation was possible in 24 rats. The 24 transplanted rats which managed to survive were divided into three groups of 8 rats according to the different time in which blood samplings were to be done, at 2 weeks, 4 weeks, and 6 weeks. After the blood samplings, nephrectomy of the testis transplanted kidney was done. Among the 2 weeks group, one rat died during the experiment and one rat had the transplanted testis unilaterally. Among the 4 weeks and 6 weeks group, 2 rats died from each group, and in the rest 6 rats, the transplanted testes remained in both kidneys. The serum testosterone levels of transplanted group at 2, 4, 6 weeks, the control group of 2 weeks after the castration, and the normal mature rat(about 10 weeks old) showed significant difference(p= 0.001). However, the serum testosterone levels of the transplanted group for 2 weeks and the control group of 2 weeks showed no difference(p= 0.665). The serum testosterone levels of the transplanted group for 4 weeks and 6 weeks did not reach the level of the control group at 4 weeks and 6 weeks(p= 0.020 and 0.030), but their increase was definite. The differences in the Leydig cells of the control group and the transplanted group were observed, and in the control group, the development of the Leydig cells were nonspecific as compared to the somewhat hyperplastic findings in the transplanted group. The morphologic differences of the Leydig cells between these two groups were difficult to be found under an light microscope. In order to classify Leydig cells according to the developmental stage and to understand the functional aspects, the followings are needed to be studied further: the ultrastructural analysis of the Leydig cells; the interactions and changes between Leydig cells and other cells in the testis tissue; measurements of the receptors of the various sex hormones. These studies are thought to be contributory to the in vitro culture of Leydig cells as well as to the clinical applications of the testis transplantation.

The most common fracture about the elbow joint in chilren is a supracondylar fracture. The displaced fracture is difficult to manage due to the potential danger of Volkmann's ischemia, nerve injury, and malunion, During the period of 6 years from June, 1979 to June, 1985, 63 children with supracondylar fractures of the humerus were treated at Pusan Paik Hospital, Inje Medical College, and analyzed. The results are summarized as follows: 1. The average age was 7.1 years, ranged from 1 year to 14 years, and the male and female ratio was 2.5: l. 2. In type of fracture, extension type was 92% and flexion type was 8%. In displacement of fracture, Grade I was only 2 cases, Grade III and IV were 87.3%. Posteromedial displacement was 42.8% (27 cases). 3. At the time of admission, 15cases(23.8%) accompanied nerve injury, of these median nerve injury (9 cases) was most common. All the patient with nerve injury were completely recovered within 14 months after reduction. 4. Severe cubitus varus was 14.2%, and severe limitation of elbow motion was 1.6%. 5. Of 61 displaced fractures, 37 patients were treated with closed reduction and percutaneous pin fixation. By Flynn's criteria, satisfactory results were obtained in 36 of the 37 patients(97.3%) treated with percutaneous pinning. 6. In the displaced fractures, closed reduction and percutaneous pinning is a satisfactory method for obtaining and maintaining reduction while preserving vascular function, if acute flexion is necessary for stable reduction.

The standard treatment of adult femoral shaft fractures is the closed intramedullary nailing using a fracture table, but in polytraumatized patients, this method may be difficult due to concomitant adjacent injury. So, we report on the technique of closed intramedullary nailing without a fracture table for adult femoral shaft fracture using "joystick" technique on radiolucent table in supine position. Among 15 cases, two were open fractures, three were proximal 1/3, seven were middle 1/3, two were distal 1/3, and theree were segmental fractures. According to the Winquist Hansen classification, five type I, four type II, three type III, three were type IV. The eleven patients out of the fifteen were operated within 48 hours. The average operation time was 105 minutes, and the amount of bleeding was below 300cc. Forty-seven percent was anatomically reduced, forty percent had below five degree of angular deformity or below five milimeter of shortening, thirteen percent had above five degree of angular deformity of above five milimeter of shortening. The closed intramedullary nailing of femoral shaft fractures without fracture table using radiolucent table and "joy stick" technique is an effective and safe method in multiple injuries. And it reduced the operation time by reducing the preoperation time including preparing of a fracture table.

Tuberculous spondylitis is not rare disease. Today the posterior instrumentation and posterior or posterolateral fusion concomitant with the anterior decompression and anterior interbody fusion have been used for the treatment of spinal tuberculosis. The authors experienced a case of tuberculous spondylitis complicated with descending aortic pseudoaneurysm. An aneurysm is defined as a localized dilatation of an artery that is at least one-half the size greater than is expected for that artery. Pseudoaneurysm occurring after previous operation, trauma, and infection. Erosion of the thoracic aorta with the development of an fistula in the presence of infection is an unusual and difficult problem to manage. We report a case and review related articles briefly.

Although the management of fractures of the calcaneus still remains controversial, open reduction and internal fixation is gaining in popularity as the method of choice for the treatment of displaced intraarticular calcaneal fractures. However, open methods can make several complications such as neurovascular injury and infection. Thus we have performed the new technique of arthroscopic reduction and minimal internal fixation for displaced intraarticular calcaneal fractures in 5 cases. The results were evaluated between 12 and 16 months after surgery. A Bohler angle was restored to 25degrees-40degrees in all cases. Anatomical reduction of articular surface were obtained from 4 cases out of 5. No complications were found except 1 peroneal tendinitis. The clinical results by Creighton-Nebraska health foundation assessment for fractures of the calcaneus were 3 excellent, 1 good and 1 fair. Even though this was a few case and a short term follow-up study, the arthroscopic assisted management of displaced intraarticular calcaneal fracture induced a little complications and satisfactory results.
