PURPOSE: We measured the bone mineral density (BMD) of the cortical and cancellous bone of the lumbar spine in women by using QCT to evaluate the influence of the aging process and menopause on both bones. MATERIALS AND METHODS: The BMD of cancellous and cortical bone in L1, L2 and L3 was assessed by QCT in 510 patients from 1997 to 1999. RESULTS: The rate of cancellous bone loss was more markedly increased than that of cortical bone with aging process and menopause, while the density of cortical bone was more effective to whole bone density. Cortical bone density and whole bone mineral density were higher in L3 than L1 vertebra. On the contrary, the cancellous bone density was higher in L1. CONCLUSION: The BMD of cancellous bone decreased a lot more than that of cortical bone in postmenopausal women. We conclude that preventing cancellous bone loss is of the utmost importance for the prevention of osteoporosis after menopause.

The purpose of this retrospective study was to evaluate the morphology of the intercondylar notch of the knee in 72 anterior cruciate ligament (ACL) intact group and 30 acute and chronic ACL tear group by plain radiographs and MRI, and to find the predisposing factors of ACL tear. The ACL tear group was divided into acute and chronic ACL tear group. In plain lateral radio-graphs, beta angle, angle between extension line from anterior cortical line of distal femur and from Blumensaat s line, was measured. In magnetic resonance imaging, the width of intercondylar notch (NB), the widest width of both femoral condyle (NW), intercondylar notch width from lower one third point of notch basal line (NB1), intercondylar notch width from upper one third point of notch basal line (NB2), depth of intercondylar notch from notch basal line (ND), and intercondylar angle which made from both end point of notch basal line and apex of intercondylar notch (alpha) were measured. Three groups were compared with each other by statistical analysis. Stastistically, the acute ACL tear group had narrow upper portion of intercondylar notch than chronic ACL tear group and more acute angle of roof of the intercondylar notch than intact ACL group. So in notchplasty, the upper one-third of intercondylar notch should be carefully widened. And after fixation of femoral interference screw, arthroscopic observation should be done whether reconstruced graft touchs the roof of the intercondylar notch during the extension of the knee.

In 1941 Wiberg discribed morphologic classification of patella in axial plane and the correlationship between its shape and dysfunction. Here the authors reviewed 120 cases and divided them into four groups. Group I is the one with no knee joint pain or patella dysfunction, group II is the patients with meniscus injury, gruop III is the patients with chondromalacia of patella and group IV is the patients with osteoarthritis of knee joint. We analysed them according to the ratio between the length of the patella and the articular surface in lateral X-ray films of patella. The results were as follows:1. The ratio between the length of the patella and the articular surface is 1.45±0.13(mean±SD) in group I, 1.47±0.18 in group II, 1.56±0.12 in group lll and 1.57±0.15 in group IV. 2. Statistically(P<0.05), no significant difference between group I and group II, but group III and group IV is significantly different from the group I. 3. The ratio between the length of the patella and the articular surface is thought to be helpful for diagnosing the patient with vague knee joint pain.

The various methods of treatment of the supracondylar fractures of the femur were adapted by many authors according to degree of the involvement of the articular surface, displacement of fragments, degree of comminution and external forces. Authors experienced the supracondylar fracture of the femur in 31 cases who were treated at Koryo General Hospital from March 1984 until March 1988 and among them, 14 cases were treated by operative methods and 17 cases by conservative methods. The results were as follows:1. The male was more common, and the 3rd & 4th decades were most. 2. The most common cause of injuries was traffic accident. 3. The most common fracture type was type I by Neer's classification. 4. The type I was treated mostly by conservative methods and the type II & III by operative methods. 5. In the operative treatments, after anatomical reduction and rigid fixation, the duration of the rehabilitation was shortened by using the C.P.M. exerciser. 6. The complications were partial ankylosis of the knee, chronic osteomyelitis, nonunion and delayed union.

The acromioclavicular and coracoclavicular ligament are usually injured by traffic accident or during sports. So, various methods of treatment has been introduced. Fourty four cases of acromioclaviclar and coracoclavicular ligament injuries were admitted and treated at Koryo General Hospital from March 1985 to February 1989. 26 cases were treated by operative method, 18 cases by conservative method in Grade 1, 2 and 3 injuries. The following results were obtained. 1. These injuries were more prevalent in male and more in left side. 2. The most common cause of injuries was traffic accident. 3. Among 44 cases, 13 cases were Grade 1, 9 cases Grade 2 and 22 cases Grade 3 by Allman's classification. 4. 18 cases were treated conservatively and 26 cases operatively. Conservatively treated 18 cases include 15 cases by Kenny-Howard sling and 3 cases by skillful neglect. And operatively treated 25 cases include 12 cases by modified Phemister method(46.2%), 2 cases by modified Bosworth method(7.7%), 2 cases by acromioclavicular plate method(7.7%), 2 cases by Stewart method(7.7%) and one case by Mumford method(3.8%). 5. There were good functional results with the K-wire fixation method after the acurate diagnosis by operative method in the Grade 2 injury. And in the Grade 3 injury we could get the functional results with the modified Phemister method.

We performed dual color fluorescence in situ hybridization (FISH) for the bcr/abl fusion in CML using the peripheral blood smears without destruction of cell morphology to determine the bcr/abl fusion. Two patients of CML, one patient in accelerated phase and one patient in chronic phase, were selected. The blood smears were fixed in absolute methanol. FISH was performed with the Mbcr/abl translocation DNA probe mixture and the slides were stained with Wright's stain after FISH. The blood smears of both cases revealed distinct signals without destruction of cellular morphology. The normoblasts and lymphocytes revealed beautiful fused bcr/abl signals as well as granulocytes in both cases. The results provide a novel finding that the normoblasts and lymphocytes in CML are also neoplastic clonal cells which has not been demonstrated with a single-cell approach before.
