Degenerative arthritis of the knee joint is one of the main causes of disability in middle-aged persons. This paper is planned by the necessity of objective information upon changes of tibio-femoral angle according to weight bearing in patients with degenerative arthritis of the knee joint. The authors studied the tibio-femoral angle in 29 cases of degenerative arthritis of the knee ranging fmm 5th to 6th decades of age, and compared with 27 cases of the control group, in the Dept. of Orthopedic Surgery, S.N.U.H. fmm Mar. 1983 to May 1984. The following observations were obtained: 1. In patients with degenerative arthritis of the knee, changes of the tibio-femoral angle according to weight bearing were +2.2±1.94 in 5th decade, +2.3±2.02 in 6th decade. 2. Compared to control group, the degenerative arthritis group showed a significant varization with weight bearing. 3. It was seemed that the weight bearing radiography is essential in diagnosis and treatment of degenerative arthritis of the knee joint.

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.

The epidermoid cyst of the testis is a rare benign lesion with a characteristic gross and microscopic appearances. This 25 year old male who had been previously diagnosed as Klinefelter's snydrome (47/XXY) had right orchiectomy due to hard testicular nodule for a presented malignant testicular tumor. Sectioning of the testis revealed a intraparenchy matous cystic lesion, 1.5 cm in diameter, filled with cheesy white material. Histologically, stratified squamous epithelium lined the cyst. The remaining testis showed advanced tubular sclerosis and Leydig cell hyperplasia. It is necessary to submit multiple sections to rule out other histologic elements in the cyst wall or the presence of a scar. Although epidermoid cyst occurring as a solitary testicullar nodule could be regarded as a stage in the development of a teratoma, they need to be distinguished from the complex differentiated teratomas because of a distinct difference in prognosis.

PURPOSE: To investigate long-term visual outcomes and prognostic factors to predict visual outcomes in patients with anatomic success after macular hole surgery. METHODS: Medical records of 36 eyes with successfully repaired stage 3 or 4 idiopathic macular hole and with at least 24 months of follow-up were reviewed. Hole height, stage of macular hole, base diameter, minimum diameter, hole form factor, macular hole index, and hole closure type were measured or calculated, and the correlations of visual outcomes with variables of preoperative optical coherence tomography (OCT) were analyzed. RESULTS: The patients were classified into 3 groups according to the time period necessary to achieve the best corrective visual acuity. The visual acuity of 16 eyes (44.4%) recovered in a mean of 6 months, 13 eyes (36.1%) improved slowly and continuously, and 7 eyes had no improvement despite successful anatomical closure. There were no statistical differences in hole height, base diameter, minimum diameter, hole form factor, macular hole index, or closure type among the 3 groups. CONCLUSIONS: The improvement in visual acuity after successful macular hole surgery persisted at the 24-month follow-up and after. There were no correlations between delayed visual acuity after macular hole surgery and minimum diameter, base diameter, hole height, hole form factor, macular hole index, or closure type.

BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

Meralgia paresthetica is a syndrome consisting of numbness, pain, tingling, burning and/or a variety of other paresthesias on the distribution of the lateral femoral cutaneous nerve (LFCN) of the thigh. We report a case of meralgia paresthetica in a 41-year-old woman who complained of the symptoms of pain, burning sensation, and dysesthesia which occurred whilst standing up without any other constitutional symptoms. The authors suspect that frequent. and persistent squatting may play a role in the development of the present symptoms.

Malignant melanoma is an uncommon tumor in Korea. To the best of our knowledge, we could not find malignant melanoma with multiple myeloma in Korean literature. A 57-year-old male patient had a 4×5 cm sized, irregular bordered, dark brownish plaque on the left sole, which has extended gradually since about 1 year ago and showed an occasional bleeding tendency. Laboratory examinations revealed a low hemoglobin level, rouleaux formation on peripheral blood, monoclonal gammopathy of IgG-kappa type and Bence-Jones proteinuria. Bone marrow aspiration findings showed markedly increased immature plasma cells suggesting multiple myeloma. Histopathologic findings of the skin biopsy from the left sole revealed proliferation of atypical melanocytes. We performed a surgical excision with a skin graft for malignant melanoma and chemotherapy (melphalan, vincristine and prednisolone) for multiple myeloma.
