Choroidal metastatic carcinoma is very rare. We recently experienced a case of lung adenocarcinoma which presented to the clinic with ocular symptoms. This 57-year-old Korean male patient visited the department of ophthalmology due to decreased visual acuity and pain of the left eye. On MRI scan, a nodule was attached to the retina of the left eyeball. On simple chest radiograph, a large amount of pleural effusion was noted in the left pleural cavity. Emergency enucleation of the left eyeball was done with an impression of malignant melanoma causing an intractable ocular pain. Grossly, the lesion in the eyeball was rising from the choroid. On histologic examination, tumor cells formed many irregular, small gland-like structures. The tumor cells showed alcian blue-positive mucin in the cytoplasm and glandular lumens and were positive for CEA. Chest CT scan was performed postoperatively and showed a huge mass in the left lower lobe and multiple nodular opacities in both lung fields. Bronchoscopic biopsy revealed moderately differentiated adenocarcinoma similar to that of the eyeball.

This review-article is aimed at shedding a light upon the nature of age-associated changes in the human skeletal system. When the anatomical, physiological and biochemical consequences of bone aging are considered together with the hardening, drying and the diminished repair capabilities of the elderly, it can be seen that fractures assume greater importance as a clinical problem in the geriatric population. Older people start out with a deficit of cortical bone, making them more fracture prone and once fractures occur, the necessary treatments (immobilization, use of casts, etc.) accelerate the rate of bone loss. In addition, aged individuals stand a higher risk for complications of the hospital and enforced bed rest that may ensue. The problems resulting from bone loss in the elderly may be partially alleviated by providing adequate health service support which should include consideration of the following points : 1. Age, sex and general health status ; 2. Habits and inclinations towards physical activities ; 3. Nutritional and endocrine background ; 4. Presence of any specific bone diseases, including osteoporosis, osteoarthritis, osteomalacia and ankylosis ; 5. Psychosocial adaptability and other behavioral elements.

We applied arthroscopy in the diagnosis of thirty four patients with internal derangement of the knee from March to August, 1982. Its results were compared with clinical diagnosis and arthrographic findings. We also performed arthrofomy in twenty nine patients and the final diagnosis enabled us to evaluate the diagnostic accuracy of each method. The accuracy of clinical diagnosis was 63.4%. Arthrographic findings were correct in 77.8%. The diagnostic accuracy of arthroscopy was 92.3% with one false negative case. Unnecessary operations were avoided in five patients with the assistance of negative findings of arthroscopy. Arthrography and arthroscopy were complementary in the diagnosis of internal derangement of the knee.

In carpal injury, a good functional end result seems to correlate with final anatomic alignment of carpus after treatment. Some cases are often misdiagnosed and result in inadequate treatment. Forty six cases of carpal injuries were analysed which were treated for 9 years from 1975 to 1984 at the Department of Orthopedic Surgery, Seoul National University Hospital. The observations can be summarized as follows. 1. The male to female ratio was 3.5: 1 and 82% of total cases were in the third and fourth decades. 2. The most frequent cause of injury was fall from height with outstretched hand. 3. Trans-scaphoid perilunar dislocation and its variant were the most common diagnosis in this analysis. 4. All of the scapho-lunate dissociation showed volar flexion intercalated segmental instability with scapho-lunate gap more than 2 mm in our series. 5. In 11 cases of trans-scaphoid perilunar dislocation and its variant, carpal collapse was found in 10 cases. In 5 cases dorsiflexion intercalated segmental instability pattern and in one case volar flexion intercalated segmental instability pattern were found to be present. 6, There was an increase in scapho-lunate angle in all cases of dorsiflexion intercalated segmental instability, but a decrease in scapho-lunate angle is not a consistent finding in volar flexion intercalated segmental instability. 7. In 24 cases more than 6 months follow-up, excellent and good results were obtained in 20 cases. 8. As a result of above findings, authors conclude that scapho-lunate gap more than 2mm has diagnostic value in scapho-lunate dissociation but that dorsiflexion intercalated segmental instability or volar flexion intercalated segmental instability only means the changes in the relationship between carpal bones and does not have definite or specific diagnostic value for a specific carpal injury.

Since the first report by Berberich and Hirsch in 1923, conventional angiography had been playing essential roles in diagnosis and treatment in the field of Orthopedic Surgery. Angiography is still the most definitive method for evaluating arterial disease, and is also an invaluable aid in the diagnosis of certain abnormalities which characteristically alter the normal vascular pattern. But the clinical use of conventional angiography as a routine diagnostic study has been limited by the risk associated with arterial catheterization cost, and poor patient acceptance. With improvement of radionuclide angiography and development of the methods for the identification and amplification of signals from small quantities of intravascular administered iodinated contrast agent and their combination with image subtraction (so called digital subtraction angiography, DSA), we have partially substituted the DSA and Radionuclide angiography for conventional angiography in diagnosis and post-operative evaluation of orthopedic patients. We have analyzed and compared the 197 cases who had taken conventional angiography from August, 1981 to July, 1985, and 16 cases who had taken radionuclide angiography from January, 1983 to July, 1985, and 21 cases who had taken DSA from October, 1983 to July, 1985 in Department of Orthopedic Surgery, Seoul National University Hospital. The results were as follow: 1. Conventional angiography is the most reliable and most widely used method in diagnosis of peri pheral arterial disease and evaluating the distribution of peripheral circulation of patient who need arterial reconstruction. But the clinical use of the angiography has been limited by the risk of complications. 2. DSA is simple, relatively non-invasive and can be done in out-patient basis. DSA is particulary useful and can replace the conventional angiography in post-operative assessment of peripheral vascular reconstruction, in the assessment of blunt and penetrating peripheral arterial trauma, and in the evaluation of peripheral aneurysm and vascular malformation. 3. Radionuclide angiography is also simple, and has no morbidity and useful in the patients who may be allergic to the contrast medium. Radionuclide angiography is useful in the evaluation of obstruction of major artery, deep vein thrombosis, and in repeated post-operative evaluation of arterial reconstruction.

In order to assess the biocompatibility of domestic dynamic compression plates and screws manufactured at KAIST (Korea Advanced Institute of Science and Technclogy), hematological, serological, histological, and metallurgical studies were carried out on sixty rabbits through thirty-two weeks. The rabbits were divided into two groups, group I: thirty rabbits for KAIST plates and screws, group II: thirty rabbits for Osteo plates and screws. The plate and screws were fixed on the fixed tibial shaft. All the resulg of hematological, serological, histological, and metallurgical study revealed that there were no meaningful differences between the two groups. This, in fact, enco.urages us to use domestic KAIST plates and screws clinically and to develop more complicated designs including total joint replacement system.
