It is clearly defined through a number of authoritative studies that the age of menarche influenced by the various combined factors such as nutrition status, physical status, physical growth and development status, socio-economic status, locality, culture, education level, climate, rece heredity etc. In order to obtain statistical data regarding the menarche of Korean school girls, anthors investigated on 4207 middle school girls and 703 woman college students in Seoul and Taegu during the period of September 10 to 30, 1973 and the result are summarized as followings; 1. The rates of menses experience by years were 18.2% in the age group of 12 years girls, 31.9% in 13 years, 64.6% in 14 years, 89.8% in 15 years, 98.1% in 16 years respectively. 2. The average age of menarche for the 2504 school girls who were born during the year of 1957-1961 is 13.4 years with the rang of 9 years to 16 years. And the most frequent age of menarche is 13 years. 3. The average age of menarche for the 703 woman college students who were born during the year of 1950-1954 is 14.3 years with the rang of 9 years to 18 years. And the most frequent age of menarche is 13 years. 4. The apparence of menarche is most common in August (20.7%) for the group who were born during the year of 1957-1961 and most rear in November (4.2%). And it is also most common in August (19.9%) for the group who were born puring the year of 1950-1954 but most rear in June (3.4%).

Congenital pseudarthrosis of the tibia is a relatively rare but well known entity. Aside from the fibula, which is aften associated with tibia, the clavicle is probably the next preponderant site. Congenital pseudoarthrosis of other bones are extremely rare. We have found 10 cases of congenital pseudarthrosis of either the radius or the ulna in the English literature. Only one case of congenital pseudarthrosis of both bones of the forearm has been reported to our knowledge, A 30 year old man with congenital pseudarthrosis of the radius and the ulna associated with neurofibromatosis was seen at Seoul National University Hospital in March, 1985. Osteosynthesis was successful on the radius, but failed on the ulna. The distal fragment of the ulna eventulally disappeared altogether.

These days the posterior chamber lens implantation following the extracapsular cataract extraction has become the standard procedure except those patients who cannot take it in one reason or another. In past, however, the anterior chamber lens implantation was popular for sometimes. Even now in those patient complicated by vitreous loss, the anterior chamber lens implantation following anterior vitrectomy is indicated in some cases. We have become interested in the difference of the intraocular pressure change in the patients who underwent the uneventful extra-capsular cataract extraction followed by anterior chamber lens implantation in routine manner and in those whose extra-capsular cataract extraction were complicated by vitreous loss and eventually needed the anterior vitrectomy before the anterior chamber lens implantation. We reviewed the medical records of 15 cases of the former group and 11 cases of the latter one in 1986 through 1988. There was some difference in the postoperative pressure in the two groups, but it was not statistically significant.

From 1963 to 198I, we have performed Colonna's capsular arthroplasty on 7 children. Three of the hips had congenital dislocations and four hips had pathologic dislocation. The results on these cases, including some long term follow-up were satisfactory. Since Colonna first published his technique in 1932 ideal indications for the classical arthroplasty have largely been replaced by those of more recently developed procedures such as Salter's innominate osteotomy, Chiaris osteotomy and etc. We feel, however, that there still seems today a narrower, but distinct domain of usefulness left for the capsular arthroplasty, and that new indications need to be redefined. We propose the following criteria for such purpose. First, congenital dislocations of the hip in children beyond 6 years of age, which is the upper age limit of Salter's innominate osteotomy, and below 8 years of age, which is the upper age limit o original Colonna's capsular arthroplasty. Second, teratogenic congenital dislocations in which the shallow and slanted acetabulum renders otherwise stable, deeply seated acetabulum with a prospect for a concentric remodelling unlikely. Third, pathologic dislocations secondary to septic hip in children 3 to 8 years of age in which a pain-free, stable and reasonably mobile hip often betrays rentgenographic imaginations and renders reconstructive procedures in adult life feasible.

Slipped femoral capital epiphysis is a rare entity in Korea and only three cases have been reported so far1,2,3). One of our cases was a unilateral mild chronic slip in a 14 year old boy with Frohlich body type. It was treated by gentle closed reduction followed by knowles' pin fixation. The other case, a 20 year old female, presented chondrolysis of the left hip. Scrutinization of roentgenograms revealed typical features of an unrecognized slipped femoral capital epiphysis. It was treated by Wagner resurfacing replacement arthroplasty.

Oncogenous or tumor-induced rickets is recognized as Vitamin D-resistant hypophosphatemic rickets that heals after excision of a coexisting tumor in either bone or soft tissue. Its pathogenesis is not clarified, but it has been suggested that the tumor elaborates a homoral substance inhibiting tubular reabsorption of phosphate or that the tumor inhibits the synthetic process of 1, 25-dihydroxcholecalciferol. We present two cases of vitamin D-resistant rickets, one associated with intrasseous well-differentiated osteosarcoma in the pelvis and the other associated with fibrosarcoma of distal femur. The case with low grade osteosarcoma showed immediate improvement of rickets after excision of the tumor, but the case with fibrosarcoma showed no improvement after amputation and was fatally terminated 5 months later due to lung metastasis.

The purpose of this experiment was to determine the effect of dividing the periosteum circumferentially on the growth of long bones and the effect of partial division of the periosteum on the formation of angular deformity of growing bones and to investigate the tethering effect of the periosteum on the epiphyseal plate as its possible mechanism. One hundred twenty rabbits, one-month old with average weight of 570g, were divided into four groups. In the first group, the periosteum of the right distal femur was completely divided circumfer- entially; in the control group, the medial aspect of the right distal femur was surgically approached but the periosteum was not divided, in the third group, the medial half of the peristeum of the right distal femur was divided transversely; in the fourth group, the medial half of the periosteum was divided and resutured. Following the operation, X-rays were taken every two weeks until twelfth week and then at twentieth week and the length of the femur and the physis-shaft angle were measured. l. After complete circumferential division of the periosteum, the ratios of right over left femoral length before operation, and two, four, six, eight, ten, twelve, and twenty weeks postoperatively, were 100.0±0.0%, 102.1±0.1%, 102.±0.0%, 102.9±0.0%, 103.5±0.0%, 103.6±0.0%, 103.5±0.0%, and 103.5±0.0%, respectively. The overgrowth was most conspicuous during the first two weeks. On the other hand, in the control group there was slight overgrowth, but this was not statistically significant. 2. After partial division of the periosteum, the physisvhaft angles before operation, and two, four, six, eight, ten, twelve, and twenty weeks postoperatively, were 91.0±1.2, 87.8±2.5,84.4±2.4, 83.1±3.2, 84.2±3.5, 86.4±2.3, 86.2±2.3, and 86.8±1.9, respectively. The valgus deformity was induced most conspicuously during the first four weeks, whereas partial correction of the de- formity took place between the eighth and tenth week postoperatively. After repair of the partially divided periosteum, only 0.9 of angular deformity was observed at sixth week, but this became statistically insignificant at tenth week as were in the complete division and control groups. 3. Histologically, no difference was observed in the cartiage cells of the epiphyseal plate and the bony trabeculae of the metaphysis between the control group and other groups. The divided periosteum regenerated at the ninth week, this being same also in the repaired group. There was no statistical difference in the thickness of the epiphyseal plate between the operated femur and the opposite normal femur in the completely divided group, this being same in the control group. Threr was also no statistical difference in the thickness of the epiphyseal plate between the medical and lateral halves in the partially divided group, this being same in the repaired group. Based on these results, the investigator was able to draw following conclusions. 1. In the growing long bone, complete circumferential division of the periosteum near the epiphyseal plate results in stimulation of growth and lengthening of bone. 2. Partial transverse division of the periosteum results in asymmetrical overgrowth, inducing an angular deformity. 3. It is suggested that the mechanism of overgrowth following division of the periosteum lies in the removal of the tethering effect of the periosteum. These findings may bear clinical implications on leg length inequality and angular deformities following certain fractures and epiphyseal injuries during growth period.

BACKGROUND: Korean Instrumental Activities of Daily Living(K-IADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of K-IADL scale. METHODS: Clinical validity and convergent validity was tested. Reliability was tested by internal consistency(Cronbach`s alpha), two weeks test-retest method, and interrator correlation. RESULTS: Cronbach`s alpha was 0.938. 2 weeks test-retest correlations in all 10 items were higher than 0.674. Interrator agreements were high in all 10 items(H=0.808~0.947). Normal control group had lower scores than patients group in all 10 items(p=0.000). Correlation coefficient between K-IADL score and brain-disability grade was between -0.336(laundry) and -0.663(using transportation)(p=0.000). CONCLUSIONS: Korean Instrumental Activities of Daily Living(K-IADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-IADL and mortality, prognosis are needed.
