Fractures of the femur are one of the most frequent injuris which Orthopedic Surgeons are called upon to treat. The incidence of femoral fractures has risen by the results of rapid increase in traffic accident, industrial accident, and prolongation of life expectancy in adults. Two hundred and ninty eight consecutive femur fractures were treated at the Department of Orthopedic Surgery, Hanyang University, during the period of May 1972 to September 1977 were reviewed. The results were as follows; 1. The fractures occured commonly in the 6 to 10 years age group (46.1%) in children and in the 21 to 40 years age group (48.2%) in adults. Males comprised 217 cases (71.1%). 2. Fractures were caused by traffic accident (72.2%) mainly and especially in old aged fractures of the femoral neck and intertrochanter were caused by fell down from a height. 3. Closed fractures were 258 cases (84.7%) and transversefractures were the most common type in, children, and comminuted fractures were the most common type in adults. 4. The freguent fracture site was transcervical fracture of femoral neck, type 3.4 (by Tronzo) of the. intertrochanteric fracture and middle third of femoral shaft. There were no differences between medial and lateral femoral condyle fractures. 5. Associated injuries were common in young adults in 165 cases and in order of frequency, these were fractures of the tibia and fibula, pubics, skulls, patella and ribs etc. 6. Better results were obtained with conservative treatment in children and operative treatment in adults. 7. The period of bony union in children was 7.6 weeks with Bryants traction 9.3 weeks with Russel traction, 8.6 weeks with cast immobilization, 10 weeks with 90-90 skeletal traction and 10.8 weeks with Bohler-braun skeletal traction. 8. The period of bony union in adults was 17 weeks with Kuntscher nail, 13.6 weeks with compression plate and screw fixation, 18 weeks with Bohler-braun skeletal traction and 19weeks with cast brace in femoral shaft fracture. 9. Complications were much more frequent in adults than in children and it were treated well Postoperative infection was occured in 5 cases (1.7%) and they cured well with sequestrectomy, curettage and continuous antibiotics administration. 10. The Bryants traction under 2 years of age, 90-90 skeletal traction over 5 years of age in children and compression plate and screw fixation in adults were further recommended.

Although the primary repair has been recognized so far, the tendon graft is reported as a primary treatment method for tendon injury in no man's land of Bunnel, judging from the state of injured hand, the ability of operator and the environment of medical operation. The 27 cases of tendon graft that were operated for 11 years from June, 1973 to June, 1984 in the Department of Orthopedic Surgery, Hanyang University College of Medicine have been followed up for clinical study. The results were as follows: 1. The Material of this study was composed of 13 males (21 cases) and 5 females (6 cases) whose age were from 8 to 39 years old. 2. The injured fingers were classified with 3 thumbs, 6 index fingers, 7 middle fingers, 8 ring fingers and and 3 little fingers out of 27 cases and all injured parts of fingers were Zone II except that of thumb which was Zone IV of Bunnel. 6 patients were injured more than 2 fingers. 3. The duration from tendon injury to tendon graft which scattered from 1 month to 9 years and averaged out to 28.2 months is supposed to have little relation to post-operative results. 4. The post-operative results showed up 9 excellent, 7 good and 1 fair out of 17 cases in good gmup, 3 good and 6 fair out of 9 cases in cicatrix group, 1 fair out of 1 case in nerve damage group at pre-operative state. 5. The post-operative results of thumb which show up 2 excellent, 1 good out of 3 cases were most successful among those of all fingers. 6. The pre-operative state is supposed to have great relation to post-operative state judging from 94% satisfactory results of good group at pre-operative state. 7. As multiple injury makes little difference from single injury, the injured state of each hand is supposed to an important effect on post-operative results. 8. As all electric bumed injury show up fair except that of thumb, they are supposed to have unsatisfactory results.

BACKGROUND: The purpose of this study is to administer conservative treatment in 30 patients diagnosed with idiopathic frozen shoulder, following the suggested frozen shoulder rehabilitation program and to assess the clinical outcome using a prospective study. METHODS: Thirty patients diagnosed with idiopathic frozen shoulder, treated with steroid hormone injection on the articular joint with an intra-articular steroid (triamcinolone 40 mg + lidocaine 4 ml) injection and started on stepwise shoulder extension exercise were chosen. The subjects were divided into two groups of 15 people each with one group undergoing rehabilitation with continuous passive motion (CPM) and the other group without it. Follow-ups were done before rehabilitation and at 4-week intervals with the 24th being the final week. At every follow-up, passive range of motion (ROM) was measured and surveys on pain and clinical score were administered. RESULTS: In the last follow-up, both groups showed statistically significant improvements in all evaluation criteria. However, no statistical difference in all values of the ROM and Constant score evaluation criteria was observed between the groups. Only in the last follow-up, group 1 had a visual analog scale (VAS) score of 2.4 +/- 2.1 points, which was lower, with statistical significance, than the VAS score of group 2, which was 4.4 +/- 3.1 points (p<0.001). CONCLUSIONS: Study using CPM in treatment of frozen shoulder has been inadequate, meaning that there is still room for improvement and need for more study on setting a more specific protocol and guidelines for this procedure.

Incipient changes of the periodontal tissue in the pressure zones of rat molar subjected to the experimental force were studied by the transmission electron microscope. Experimental animals were consisted in 3 control and 21 experimental rats, of which one maxillary first molar was moved buccally with a fixed appliance which were exerting the force of 15 gm. After experimental period of 1 hour, 3 hours, 6 hours, 24 hours, 2 days, 3 days and 7 days, the animal were sacrificed with cardiac perfusion of 2.5% glutaraldehyde in the sodium cacodylate buffer and the experimental teeth with surrounding periodontal structures were processed for electron microscope. At the beginning of the tooth movement, periodontal ligaments of the pressure were compressed and collagenous fibers were arranged parallel to the root of the teeth and cell free zones in company with cell necrosis were followed. Cell free zones at the periodontal ligaments appreared in the 3 hour survival group, and getting severe with time lapse it became widespread in 2-3 day survival group and undermining bone resorption as a healing process was observed in 7 day survival group. Dilatation of mitochondria and swelling of the rER in the fibroblast and other connective tissue cells in the periodontal ligament were observed in the 3 hour survival group, which were characteristics of the incipient changes in the compressed periodontal ligament. Dilatation of nuclear membrane and pyknosis were followed by the destruction of the nucleus and cell membrane. There were no evidence in cell damage or necrosis of the alveolar bone adjacent to the hyalinized area of periodontal ligaments.

A case of femoral lengthening was performed at the Hanyang University Hospital for a 29 year old male patient who hed a 3.0 cm shortening of the left lower extremity. This patient incurred a comminuted segmental fracture of the left femur in a car accident in 1969 when he was 21 years old. At that time, open reduction and internal fixation with Kuntscher nail was done at a private clinic. The fracture was united firmly, but shortening of the left lower extremity developed progressively. At the time of admission to our hospital in 1976, he had a 3.0 cm shortening of the left femur on scanogram and complained of limping. Femoral lengthening was employed by step cut Z ostectomy on the left femur and 3.0 cm lengthening was achieved during the operation by traction with 2 Steinmann pins, one of which was inserted vertically in the greater trochanter, and the other was inserted horizontally in the distal femur. A special plate and screws were modified at our hospital and were attached and fixed to the osteotomy site. Bone gaps which developed after lengthening of the femur were filled with an autogenous iliac bone graft. The patient was followed up for 9 months after the operation, and the last X-ray showed a firm bony union without any specific complications. On pbysical examination at the present time, there is no longer a shortening of the left lower extremity clinically and gait is normal without limping.

BACKGROUND: Vascular endothelial growth factor (VEGF) plays an essential role in promoting angiogenesis during tumor development. In addition, VEGF can mediate the inflammatory response in tumors. VEGF increases the level of neutrophil migration by upregulating interleukin-8 (IL-8) in endothelial cells in vitro. However, it is unclear if VEGF can mediate IL-8 production in vivo. METHODS: To address this issue, this study examined the effect of VEGF on IL-8 production in vivo using an adenovirus transduction and mouse ear assay. RESULTS: Adenovirus-encoded VEGF (VEGF-Ad) increased the level of IL-8 production in endothelial cells in vitro compared to the control-adenovirus (CTL-Ad). The mouse ear assay showed that VEGF-Ad increased the level of IL-8 production in the endothelium. Immunohistochemistry showed that the IL-8 proteins were expressed in the vasculature within a human glioblastoma, which is known to strongly express VEGF. CONCLUSION: These results suggest that VEGF can mediate the inflammatory response in endothelial cells in vivo via the up-regulation of IL-8.
