Differential diagnosis between physiologic bow legs and nonphysiologic bow legs is difficult and still not fixed in diagnosis, especially under 5 years old age. Recently the problem exist in differential diagnosis and treatment method of rickets because of non-specific laberatory finding in rickets. Metaphyseal-Diaphyseal angle in distal femur, Diaphyseal-Diaphyseal angle between femur and tibia, and Metaphyseal-Diaphyseal angle in proximal and distal tibia, and Metaphyseal-Metaphyseal angle in tibia are measured and compared for 30 bow legs children. And divided into rickets group and physiologic bow legs group by clinical and laboratory findings. The results are as following 1. Mean age was 1.91 years old at initail examination, 2.08 years old in rickets group, 1.73 years old in phisiologic bow legs group. 2. Diaphyseal-Disphyseal angle between femur and tibia was 18.12 ±6.80 in rickets group. And 10.17±5.36 in phisiologic bow legs group. Metaphyseal-Diaphyseal angle in distal femur was 10.88±3.62 in rickets group. And 8.42±4.42 in physiologic bow group. 3. Metaphyseal-Diaphyseal angle in proximal tibia was 11.50±2.56 in rickets group. And 7.17±2.01 in phisiologic bow legs group. It's angle in distal tibia was 10.50±3.86 in the former and 9.50 ±3.09 in the later group. Metaphyseal-Metaphyseal angle in tibia was 20.68±3.91 in rickets group and 16.78±4.11 in phisiologic bow legs group. According to the above mentioned results. Metaphyseal-Metaphyseal angle and Metaphyseal- Diaphyseal angle in tibia are comparable to gross appearance of bow legs deformed children rater than Diaphyseal-Diaphysealangle between femur and tibia, and Metaphyseal-Diaphyseal angle in distal femur. All values are high in rchekts, statistically. Therfore measurement of above mentioned angle in simple X-ray is valuable in differential diagnosis between phisiologic bow legs and Rickets.

The cruciate ligaments are important in providing the anterior and posterior stability and usually associated with other ligament injury of the knee joint, and there are many controversies in its treatment. In general, the primary repair for the acute cruciate ligament injury was good, but some had opposite opinions in the treatment of the isolated anterior cruciate ligament injury. In acute injury, early repair of ligament and in delayed case, the reconstrution surgery of ligament was recommended. For good results, it is very important to give prompt management. Authors studies 23 cases in 16 patients with acute cruciate ligament proper injury who were treated by multiple pull out technique at the department of orthopaedic surgery, Chungnam National University Hospital from April, 1984 to July, 1988. The results were as followings: 1. The incidence was high in active male patients. 2. The most common injury was the traffic and automobile accident. 3. the tibial and femoral attachment were the most common detachment site in anterior and posterior cruciate ligament injury, respectively. 4. Isolated cruciate ligament injury was rare. 5. The results were good in 11 cases(47.8%), especially treated within one week.

We have reviewed our experiences of computerized tomography(CT) in the fracture of the spine. Between December 1983 and June 1985, we treated 33 fractures of the spine in 32 patients. We have used CT for the diagnosis of fractures of the spine in 29 cases (28 patients). Also we have used Louis scoring system to evaluate the stability of the fractured spine. The results are as follows. 1. CT has many advantages that were not given from simple radiograp hies or laminagrams. It reveals the vertebral body, vertebral column, posterior compartments and surrounding soft tissues excellently, and it is easy to interpretate. Also it can be done comfortably and rapidly without the need of manipulations. 2. We could acquire many informations from post-operative or long term following up of CT examinations. 3. If the Louis score is higher than 3, we should think it is unstable, and should take internal fixation of the vertebral column. 4. There is a correlation between Louis score and neurologic signs (p < 0.01). If there was a neurologic sign with low Louis score, less than 1, the recovery was soon, less than 24 hours. 5. According to CT findings for fragmentation or location of fragment, we can alternate an anterior decompression or a posterior decompression. 6. It is necessary to use CT as a initial diagnostic procedure with the simple radiographic examination in spine fracture.

Osteopoikilosis is an asymptomatic osteosclerotic dysplasia, initially described by Albers-Schönberg and Ledoux-Lebard and associates. This disorder is described as extremely rare. Inherited and sporadic cases of osteopopikilosis have been reported. A Case of familial osteopoikilosis is presented with a brief review of literatures.

Osteopetrosis is a rare familial disease, characterized roentgenographically by a marked increase in the radiodensity of bone and by abnormality in the shape of the long bone, especially the metaphysis. It was discovered fist by Albers-Schonberg in 1904 during an X-ray examination of a patient and is known as Albers-Schonberg disease, marble bone or osteosclerosis fragilis generalisata. We experienced a case of osteopetrosis in adult.

A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

Ligament and tendon prostheses have all suffered because of failure of the particular material that has used in the past. Various materials, including, silk, nylon, Dacron, and combinstions of other synthetic substances, have all enjoyed temporary vogues and have vogues and have all passed out of habitual use because of collapse of the material employed. In an attempt to find an alternative material for use as a tendon or ligament prosthesis, a fundamentally new approach to the problem has been used, namely, that of tendon ligament induction. Carbon fiber has an attraction as a biologic implant because of its inherently inert nature when used in the pure form. Within recent years, it has been possible to manufacture filamentous carbon fiber of high purity and constant filament size, and this material has been examined as a tendon and ligament prosthesis. Both achilles tendons of 14 adult Korean rabbits were replsced with carbon fiber reinforced epoxies(CFRE, it was developed in department of chemical engineering, Chungnam national university, Daejeon, Korea) after artificially rupture, and serial histologic examination of neotendon formations and biologic responces in vivo were done during 8 weeks. The results obtained were as followings ;1. Hemorrhage and inflammatory reactions were observed at 2–3 weeks after operations. 2. Foreign body reactions were developed at 4 weeks after operation, also observed proliferations of foreign body giant cells and histiocytes. 3. Fibroblasts were increased at 4 weeks after operation, and most severe poliferations at 5–6 weeks. 4. Foreign body reactions and fibroblasts were markedly decreased at 7–8 weeks after operation, and examination of the collagen itself showed it to be closely similar to that found on the normsl side.5. Thus, it appeared that the carbon fiber initially acted as a tendon prosthesis.
