Nasopharyngeal angiofibroma is a relatively rare, but is a well known tumor that occurs almost in male, most frequently during the adolescent stage. Its character is histologically benign but clinically malignant because of locally invasive character to the adjascent structures, massive bleeding tendency during surgical procedure and high recurrence rate after treatment. Recently many advancements diagnostic method and surgical technique has reached satisfactory result in treating this difficult tumor. The authors present a case of nasopharyngeal angiofibroma in 16 years old male patient, who was received surgical removal of the tumor through the transpalatal approach after full diagnostic evaluation and preoperative hormonal therapy.

Late aseptic loosening of the acetabular component following total hip arthroplasty become increasing frequently after about 10 years and has become a more severe problem both in frequency and severity than femoral component loosening. The complexity of acetabular revision depends largely on the reconstruction required to restore normal anatomy due to acetabular bone loss. The clinical and radiologic results of acetabular revision using a porocoated acetabular component fixed to the pelvis with screws were studied in 36 patients (40 hips) who had moderate or severe acetabular loss. Acetabular revision in patients whose bone stock had already been destroyed provied more formidable problems at revision surgery. The mean Harris hip score was improved 46 to 84. Bone graft union was achieved by 7.4 months and incorporated by 16 months. The graft bone resorption was noted minor degree lateral to the cup. Of 40 cases, 2 cases required re-revision of acetabular cup for identifiable failure of fixation and one was showed probable loosening. The results of the present study suggest that revision of the acetabulum with use of a hemispherical cementless component stabilized with multiple screws and morselized bone grafts filling bone defects appears to be successful in restoring bone stock and providing a stable, pain-free reconstruction.

Transpedicular Screw fixation and Harrington distraction rod are effective means of managing unstable thoracolumbar fracture and fracture dislocation. The authors analysed the 52patients who were treated with above 2methods from March 1986 to February 1993. The results were as follows: 1. Most of patients were in 5th decade compare to younger group and most common cause of injury was fall down, but traffic accident is increasing. 2. The most commonly involved sites were T12and L1 vertebrae and most common type of injury is bursting fracture. 3. Postoperative anterior and posterior column of vertebrae body correction rate were 35.0%/34.4% in ISF group and 29.3%/27.9% in Harrington group. Postoperative correction loss rate were 0.13/0.04 in ISF group and 0.06/0.04 in Harrington group. 4. Postoperative correction of kyphosis angle were average 18 in ISF goup and average 15° in Harrington group. Loss of correction angle was average 23° in ISF group and average 4.4° in Harrington group. 5. Range of spinal fixation was average 3.1 segments in ISF group and average 6.2 segments in Harrington group. 6. There was no significant difference in neurologic recovery between ISF group and Harrington group. The patients who had been recovered neurologically more than 1 grade were 28.6% in Harrington group and 29.2% in ISF group. 7. ISF has some benefit in spnal vertebral body height correction and in maintenance of correction compare to Harrington group. Nevertheless disadvantages of ISF group such as long operative time and possibility of cord compression by pedicular screw, ISF has advantages of almost anatomical reduction and the least spinal fusion.

After the discovery of penicillin by Fleming in 1939, a great improvement in the treatment of osteomyelitis was obtained and the mortality rate in the acute stage was markedly decreased. But, because of misuse of antibiotics, the resistance of causative organism to antibiotics and the incidence of this disease tended to increase. So, many problems in the treatment and prognosis developed. A clinical study was done of 76 cases of hematogenous osteomyelitis who were treated by authors at the Department of Orthopedic Surgery, Presbyterian Medical Center, from April 1974 to July 1981. The results were as follows: 1. The incidence in males was 1.2 times greater than in females. It occured most often in children between the ages of 11 and 15 years (58%). The most common site of involvement was the tibia and the femur in orders. 2. ESR was elevated in 77% of the patients. 3. The most common causative organism was staphylococcus aureus(+), and the penicillin resistance rate was 86%. 4. The basic management was early decompression and antibiotic administration in acute phase, and saucerization and continuous irrigation in chronic cases. 5. The recurrence was the most common complication.

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.

PURPOSE: To evaluate the results of femoral component revision with proximal modular prosthesis in 32 hips. MATERIALS AND METHODS: Thirty-two hips of thirty patients, which were revised with proximal modular femoral component due to aseptic loosening, were investigated. These patients were followed radiologically and clinically at least for two years. RESULTS: These patients were followed for an average of 2.8 years. Complications included four intraoperative femoral fractures (three at proximal, one at distal), two progressive subsidence, one infection, and one non-union and one fibrous union of the greater trochanter. Of the 32 hips, three hips were re-revised due to progressive subsidence in two and recurrent dislocation in one. Acute postoperative infection developed in one patient, who suffered from diabetes mellitus. Radiographically, satisfactory results were noted in 27 (84.7%) of 32 hips at the latest follow-up. Harris hip score was improved from an average of 47 points to an average of 93 points. CONCLUSION: This study provides encouraging results in femoral component revision with proximal modular prosthesis.
