Implant materials, for examples, plaster of Paris, Bone cement and ceramics which are used experimentally to regain shape and function, act as a scaffold for bone growth and contribute to the healing processes at bone defect developed by trauma, infection and other causes. Therefore, the effect of plastei of Paris on the bone defects of adult rabbits may be an interesting subject, particularly in the orthopedic field. The authors carried out an experiment to study the effect of plaster of Paris on the bone defect, using 30 adult rabbits weighing fmm 3000-3500 gm, which were divided into 3 main gmups. (Each group was composed of 10 adult rabbits.). In Group 1, which was the control group, made a defect at the proximal metaphysis of the tibia, 6 mm×6 mm×6 mm in size, using a drill bit and filled by hematoma spontaneously. In Group II and Group IU, a defect was also made by the same method as in Group I and a piece of Gelfoam or plaster of Paris was inserted into the bone defect respectively. Then we studied the healing processes of the bone defect by sacrifying animals of each group at 6th and 12 th week after operation. The results of this experiment were as follows. 1. New bone formarion in the bone defect was poor in group I and Gmup Il, but it was good in Group III. 2. The plaster of Paris, filling into the defect, was absorbed and removed from the site of implantation continuously and stimulated the new bone formation. 3. The Gelfoam in Group II was more rapidly absorbed than plaster of Paris and didn't stimulate the new bone formation.

The courses of the progression in the fibrous dysplasia are characterized by asymptomatic progression or spontaneous regression in some cases after the growth has ceased and the aims of treatment for a fibrous dysplasia are prevention of the pathologic fractures and correction of the deformities. The osteogenic potentiality of the cambium layer in the periosteum and the beneficial effect on the osteogenesis of the impregnating bone graft with autologous red marrow are well documented. We experienced an extensive fibrous dysplasia with cortical thinning and pathologic fracture and it was managed with subperiosteal combined xenograft of Kiel bone with autologous red marrow for the induction of cortical thickening and prevention of the pathologic fractures because of the inoperability of curettage due to extensive lesion over the entire femur, limitations in obtaining large amount of autogenous cancellous bone for the graft and lack of the facilities of the bone bank. This subperiosteal composite xenograft with autologous red marrow for a fibrous dysplasia gave an excellent result of a remarkable cortical thickening and we think this can be a type of management for a entensive fibrous dysplasia. So we are reporting this case with bibliographic reviews.

Wide resection is an acceptable alternative to amputation for the management of primary sarcomas of the long bones or pelvis. The resected bone can be debrided of gross tumor tissue, autoclaved, and than replaced to reconstruct the limb anatomically. The procedure can be combined with prosthetic reconstruction of adjacent joints with sufficient strength to allow early unprotected weight-bearing. We had an experience of a large segmental defect in the shaft of the humerus after wide resection due to.a low grade malignant chondrosarcoma without extension to the surrounding soft tissues and this case had been managed by reimplantation after autoclaving the locally resected segment and autogenous iliac bone graft with a sound union and the favorable functional outcomes. So we are reporting this case with bibliographic reviews as a possible method of reconstruction for the management of the segmental defect which was produced by a local resection for a low grade malignancy.

The incidence of spinal tuberculosis has been decreased because of the development of anti-tuberculosis drugs, the use of radical surgical procedures and the improvement in the nations general hygiene. The anterior fusion is the most frequently used surgical measure in the treatment of spinal tuberculosis. One-hundred-eighty cases of spinal tuberculosis were treated by surgery during the 5 years from 1976 to 1980 at Presbyterian Medical Center with the following results: 1. The age distribution showed the peak incidence to be in the third decade. 2. The predilection site was the lumbar area and the percentage was 43.3. 3. In 17.2% of the cases, anti-tuberculosis drug was ingested before surgery. 4. Paraplegia was present in 16.1% of spinal tuberculosis. 5. In paraplegia, most of the location of the involved bodies was in the thoracic and the thoracolumbar vertebrae and the percentage was 79.3. 6. In paraplegia, complete recovery was 82.8%, and incomplete recovery was 10.3%. 7. In 90% of the patients, anterior fusion was done and the union rate was 91%. 8. Kyphosis was the most common in late complication.

Metastatic malignant tumors involving the spine cause destruction of vertebral body, kyphosis and neural deficit. Irradiation relieves the pain and decreases the tumor mass, but sometimes the spine is progressively destroyed and becomes unstable. Traeatment of metastatic tumor involving the spine is difficult. Replacement of the vertebral body with bone cement and high dosage of radiation therapy was recommended by Harrington. The advantages are excision of the tumor mass, firm immobilization and enough irradiation not to recur. Two cases of metastatic carcinoma involving cervical spine were treated by anterior decompression, bone cement fixation and irradiation. One case died seventeen days after surgery due to severe pleural effusion. Another case was treated with irradiation (6,000 rads) after surgery and the pain was relieved. The spine is stable one year after surgery. There is no local recurrence.

The treatment of supracondylar fracture of the femur remains a difficult problem because of the wide range of portential complications. In the past, authors thought conservative treatment was superior to operative treatment of supracondylar fracture of the femur. In addition, the advent of the Cast-Brace introduced the change in concept of the conservative treatment. Recently, however, the advances in the techniques and in the devices used in intemal fixation have encouraged the operative treatment. Tibiofemoral angle, gap or stepping of the articular surface of the distal femur, range of motion of the knee, and pains in the knee were used to evaluate the following results investigated by statistical study(T-test). These clinical results were shown by analyzing 49 cases of supracondylar fracture of the femur trea ted in the Department of Orthopedic Surgery, Hallym College of Medicine, from Jan. 1980 to Dec. 1983 1. We end result of each patient was evaluated by scaled score value calculated from above mentioned criteria. 2. The mean value of the operative treatment(35 cases) was 31.03±5.52, while that of the conservative treatment(14 cases) was 27.71±4.56. 3. The mean value of the group which began the exercise of the knee joint within 2 weeks (33 cases) was 32.24±4.43. The mean value of the other group which began the exercise of the knee joint after 2 weeks(16 cases) was 25.78±4.56. This difference of means between two groups was statistically significant. Beginning the knee joint exercise within 2 weeks has large effect on the result of the treatment. 4.The results of treatment in patient over age of 50 were graded as fair irrespective of methods of treatment. 5. Various devices were used in intemal fixation but there was no difference in the results. 6. We mean value of the Tibiofemoral angle(difference from normal angle) in the operative treatment was 2.37±6.25 and that of the conservative treatment was 8.04±4.62. Both of the above method of treatment showed a varus trend, especially in the conservative treatment. In statistical study, through, there was no significance in two methods.

Author report a case of neurocysticercosis that involved the right cerebral hemisphere subcortically. The subject was 38-year-old Korean male. The headache, epileptiform seizures and left sided motor weakness were the symptoms. Simple skull X-rays showed no significant pathological findings. Right carotid angiogram disclosed the signs of a large mass in the centrosylvian region. CT scan also demonstrated large, multiple and round cystic lesions within the substance of the brain itself in the right frontoparietal region. At operation cyst wall and cysticercus in the fluid content of a mass were obtained. Postoperatively with the aids of occurrence of cysticercrus in the skin and positive serologic test, the diagnosis again confirmed.

We have recently managed a patient, 31-year-old male, who has been in the state of inferior paraparesis due to cervical disc herniation. The centrally herniated disc material was removed through the posterior approach to the lesion under the general anesthesia in left lateral position. Two days after the operation with removal of herniated disc at C5-6interspace, the subject developed quadriparesis and difficulty in urination in which the weakness of upper extremities were more severe that of the lower extremities. The signs developed postoperatively were very much compatible with those of central cord syndrome, There was improving after the removal of the hematoma and of additional herniated material at second operation which was forced to be done due to development of central cord syndrome in severe degree following the primary surgery. Recovery from neurological dysfunction in order of good and better improvement was of leg, arm, voiding and finger.
