We assessed the accuracy of Goldmann or Schi-(phi)tz tonometric readings in the gas filled vitrectomized eyes. We performed pars plana vitrectomy with or without lensectomy in 8 rabbit eyes, and in 6 enucleated porcine eyes. Fluid-air exchange was done at the end of the procedure. Intraocular pressure was measured using Goldmann tonometer and Schi-(phi)tz tonometer and was compared with true pressure which was monitored by manometer with indwelling catheter in the intravitreal cavity. Goldmann and Schi-(phi)tz tonometry always showed lower presure value than manometeric one(P<0.05) and the discrepancy was greater at higher range of intraocular pressure. Between these two methods Goldmann tonometry was more accurate in the rabbit eye (P>0.05).

Congenital pseudarthrosis is frequently associated with various stigmata of neurofibromatosis, particularly Cafe-Au-Lait spots and,subcutaneous nodules and in these patients, it is noteworthy that the treatment is very difficult even with extensive operative approach. Also it is interesting to find many controversies on etiological relation between neurofibroma and pseudarthrosis, per se and even the existance of nerve element in and around the tissue of pseudarthrosis. A thirteen years old female patient with definite neurofibromatosis associated with congenital tibial pseudarthrosis treated by intramedullary nailing and massive bone graft is reported.

Foreatiers disease is a peculiar type of ankylosing hyperostosis of the spine characterized by ossification of the anterior and right lateral aspects of the vertebral column, particularly in the thoracic region. The clinical, pathological and reontgenographic features of the disorder allowed its differentiation from other spinal diseases including ankylosing spordylitis and osteoarthritis. A case of Forestiers disease is presented with brief review of literatures.

This study was conducted to determine the level of inflammatory cytokines in the cerebrospinal fluid (CSF) of patients with meningitis. All the CSF of the patients were examined by Gram and acid-fast stain, culture, and PCR for Mycobacterium tuberculosis and Mycoplasrma spp..The levels of sugar, protein and leukocytes count were also evaluated in the CSFs. Concentrations of Interleukin (IL)-1B, IL-6, IL-8, tumor necrosis factor (TNF)-a in the CSF were evaluated by the ELISA kit (Genzyme, USA). General bacteria, tubercle bacilli, and Mycoplasma spp. were not detected with stain and culture methods, but, Mycoplasma spp. was detected by PCR method from four (6.3%) patients with meningitis. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-cx in the control group were 0.6+/-0.2, 896.8+/-107.6, 50.1+/-5.1, and 4.8+/-1.4 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with aseptic meningitis were 3.8+/-0.6, 1261.6+/-144.3, 466.7+/-42.3, and 10.8+/-2.0 pg/ml, respectively. The mean CSF concentration of IL-1B, IL-6, IL-8, and TNF-a in the patients with mycoplasmal meningitis were 10.2+/-8.1, 1979.5+/-133.8, 459.7+/-96.4, and 17.5+/-5.1 pg/ml, respectively. There were significantly differences in the levels of IL-1B, IL-6, IL-8, and TNF-a between control and patients with aseptic meningitis or Mycoplasmal meningitis (each p<0.001). These results suggest that increased levels of IL-1B, IL-8, and TNF-a could be higly suggestive of meningitis.

BACKGROUND: We investigated the effectiveness of fibular strut allograft augmentation of proximal humerus fractures to prevent varus deformity in patients over the age of 65 years with insufficient medial support. METHODS: We analyzed the clinical and radiological outcomes of locking plate fixation with adjunct fibular strut allograft augmentation in 21 patients with proximal humeral fractures. The inclusion criteria were age (65-year-old or older); presence of severe medial comminution; inadequate medial support; and those who could participate in at least a one year follow-up. The average age was 76.4 years. We analyzed each patient's Constant score, our indicator of clinical outcome. As radiological parameters, we analyzed time-to-bone union; restoration of the medial hinge; difference between the immediately postoperative and the last follow-up humeral neck-shaft angles;; and anatomical reduction status, which was assessed using the Paavolainen method. RESULTS: A successful bone union was achieved in all patients at an average of 11.4 weeks. We found that the average Constant score was 74.2, showing a satisfactory outcome. The average difference in the humeral neck-shaft angles between the immediately postoperative time-point and at the final follow-up was 3.09°. According to the Paavolainen method, the anatomical reduction was rated excellent. The medial hinge was restored in 14 of 21 patients. Although we did not find evidence for osteonecrosis, we found that a single patient had a postoperative complication of screw cut-out. CONCLUSIONS: Fibular strut allografting as an adjunct treatment of proximal humeral fractures may reduce varus deformity in patients with severe medial comminution.

One case of osteoid osteoma in the lamina of the fifth lumbar spine with hamstring muscle tightness was experienced and successfully treated by surgery at the department of orthopedic surgery in Seoul National University Hospital. Literature on the subject was reviewed in detail.

Discoid semilunar cartilage is an abnormality in which the meniscus is discoid rather than semilunar, and first reported by Young of Glasgow in 1889. 13 cases of discoid semilunar cartilages which were experienced at the Department of Orthopedic Surgery, College of medicine, Seoul National University from Jan. 1956 till Aug. 1972 are reported with review of literature. 1) The incidence was remarkable higher in the male than in the female as 11 versus 2, and higher in the age group of second decade (Average 16.4 year old). 2) Most common site was lateral meniscus, and bilateral discoid meniscus were 3 cases. 3) 3 cases out of 13 cases had complicated rupture of semilunar cartilage, and one case had cyst of the meniscus. 4) Meniscectomy were performed in all cases with successful outcome.

Marfan Syndrome is a rare congenital disease characterized by the abnormalities of Sheletal system, eye and cardio-vascular system which was initially desiribed by Marfan in 1896. One case of marfan syndrome was treated at the department of Orthopedic Surgery, College of Medicine, Seoul National University for multiple skeletal deformities. Moderate degree of scoliosis was treated with Milwaukee brace and finger deformities with Z-plasty and full thickness skin graft.

Two hundreds cases of spine tuberculosis were treated surgically for the period of 7 years between 1970 and 1976 at Seoul National University Hospital and following results were obtained. 1. Many patients failed to be treated with conservative method. Spontaneous fusion was found in 10% of 200 cases with long duration of disease. Anterior fusion was performed in 166 cases and posterior fusion was carried out in 34 cases. In those 34 cases, anterior currettage was combined in 7 cases, anterior fusion combined in 19 cases in which 7 cases were performed anterior and posterior fusion at one stage. Posterior fusion alone was carried out only in 8 cases. 2. Anterior fusion is indicated for: a. decompression in cord involvement b. confirmation of diagnosis c. involvement of one joint space in children d. mild to moderate kyphosis in adult 3. Anterior and posterior fusion is indicated in: a. severe kyphosis for solid funsion b. involvement of more than two joint spaces in children to prevent increasing kyphosis c. one stage operation was technically possible and has many advantages 4. Posterior fusion is indicated in: a. poor general condition b. technically difficult cases.
