This study was designed to evaluate of the effects ofB-estradiol, progesterone, dexamethasone, hydrocortisone, calcitriol and alfacalcidol on the cell proliferation and differentiation in the rat osteoblast-like osteosarcoma cells ROS 17/2.8. The proliferation of ROS 17/2.8 cell treated with 1 M B-estradiol, 1 M progesterone, 1 M hydrocortisone, 1 M dexamethasone, 10 (-8) M calcitriol and 10 (-8) M alfacalcidol was decreased by 19%, 56%, 60%, 64%, 28% and 38% of control, respetively. Production of TGF-Bl by ROS 17/2.8 cells treated with B-estradiol, progesterone, hydrocortisone, dexamethasone, calcitriol and alfacalcidol was elevated by 30%, 18%, 60%, 48%, 405% and 452% of control, respectively. Alkaline phosphatase activity of ROS 17/2.8 cell treated with hydrocortisone, dexamethasone, calcitriol and alfacalcidol was increased by 3.4 times, 12.9 times, 10.0 times and 5.1 times of control, respectively, but with B-estradiol and progesterone decreased by 39% and 10% of control respectively. Northern blot experiments demonstrated that calcitriol and alfacalcidol increased mRNA levels of both osteocalcin and osteopontin.

The fractures of tibial shaft are common and open injury are also frequenly accompanied. Since the AO unreamed interlocking nail is solid type compared to present tubular type nail, it has no dead space, and without reaming the intramedullary blood supply can be preserved and the soft tissue trauma can be minimized. Therefore it can be used with minor risk of infection in the treatment of open tibial shaft fractures without secondary operation such as in the cases using external fixaters. Especially in Orientals, whose tibial medullary canal is narrower than Smm, it can be used ideally. From October 1991, we have experienced 14 cases of tibial shaft fractures treated with AO unreamed interlocking nail. Among 14 cases, the open fractures were 8, 4 cases were type 1 and 4 cases were type 2 by Gustilo classification. Among 6 cases of closed fractures, 4 cases had risk of post operative infection due to accompanying soft tissue injuries, such as abrasion or bulla and 2 cases had narrow intramedullary canal less than 8mm. There was no postoperative infection in all cases including open fractures, and the soft tissue defect could be reconstruted by muscle transfer, etc. The AO unreamed interlocking nail is thought to be recommendable in the treatment of open tibial shaft fracture, closed fracture with risk of postoperative infection, and also the fracture with narrow canal diameter less than 8mm.

Recently, tuberculosis of bone and joint is decreased with good nutrition and environment, development of preventive medicine and improvement of treatment regimen. But it is still one of the common inflammatory diseases in Korea, and must be considered in the differential diagnosis of common orthopedic complaints. There are few reports on extraspinal tuberculosis of bone and joint. Forty one cases of extraspinal tuberculosis of bone and joint were studied in our department from January 1988 to August 1993. The results were as follows; l. Extraspinal tuberculosis of bone and joint were 41 cases (39 patients, 27.8% of 147 tuberculosis of bone and joint including spine). 2. The proportion of children and young adults was 56%, hips were involved in 11 cases, knee joints in 8 cases, ankle joints in 6 cases, feet in 6 cases and elbow joints in 5 cases. 3. Coexisting pulmonary tuberculosis was found in 19 patients and active lesion in 15 patients. 4. Confirmative diagnosis could be made by smear and culture of the lesion or pathologic findings or recently available polymerase chain reaction(PCR) method. 5. Various treatment, such as antituberculous medication, external immobilization, synovectomy, curettage and bone graft, arthrodesis, had been carried out. 6. Reactivation of other site was found in 7.3%(3 cases) and resistant tendency was found in 9.7%(4 cases).

To evaluate the results of anterior decompression and fusion with autogenous bone graft for cervical disc disease, the authors reviewed 18 cases of cervical disc herniation which were treated surgically at Inje Univ. Paik Hosp. from 1990 to 1994 with special interest in the thickness of the bone graft. All cases have been followed for more than 12 months. We try to know the clinical results of anterior decompression and fusion with autogenous bone graft. At this treatment, controversial point is a ideal thickness of graft and the width of distraction. Therefore, we follow up the correlation between thickness of graft on roentgenogram and clinical results. The clinical results were satisfactory as excellent in 11 cases, good in 5 cases according to criteria of Robinson et al. Successful fusion occured in 16 cases within 3 months after their initial procedure, and fusion failure resulted in 2 cases. 3mm distraction from baseline disc height was considered ideal thickness of graft after anterior decompression and all cases healed successfully. We concluded that 3mm distraction from baseline disc height is necessary for successful decompression & fusion.

From Nov. 1986 to May 1988, we experienced 5 patients of bilateral recurrent patellar dislocation and obtained the following results:1. The age at operation raaged from 17 to 25 years. Among 5 patients, four were female and one, male. 2. The age at the onset of symptom ranged from 7 to 16 years. 3. The common presenting symptoms were pain(5 knees), giving way(4), grating(4), swelling (3), and weakness(2). 4. The roentgenographic findings were lateral patella tilt(9 knees), lateral femoral condyle hypoplasia(6), patella alta(2), patella dysplasia(2), and accessory ossification center(2). 5. All knees were treated by Hughston technique:One patient(2 knees) was treated with proximal realignment only, and the others(7 knees) were with proximal and distal realignments. 6. Follow up period ranged from 1 to 2 years. And the excellent to good result was obtained from the patients treated with proximal and distal realignments(excellent in 4 knees, good in 2 knees), the fair result from the patient treated with proximal realignment only(2 knees), and the poor result from the patient slipped down at 6 weeks postoperatively(1 knee).

Recently the fracture of patella has increasing tendency due to frequent traffic and industrial accidents. In this series, we treated 141 fractures of patella from January, 1980 to November, 1988 at the Department of Orthopedic surgery, Seoul Paik Hospital, Inje University, and obtained following re sults: 1. Peak age was third to fifth decades. 2. The most common cause of fracture was traffic accident. 3. Comminuted fracture was the most common type in this series. 4. Men predominate in a ratio of nearly 7:l. 5. 101 cases were treated with Modified Tension Band Wiring(41 cases), Tenison Band Wiring (21 cases), Partial Patellectomy(21 cases), Total Patellectomy(9 cases), Circumferential Wiring (9 cases). 6. The most favorable results were obtained by Modified Tension Band Wiring method as compared with other fixation techniques.
