Acetabular fractures are usually caused by violent external force such as car clash and commonly accompany injuries of the other parts of the body. And there has been long controversy between conservative and operative treatments. A clinical analysis was performed on the 29 patients with acetabular fractures, who had been treated at seoul National University Hospital from 1973 to 1982, mainly focussed on the result of treatment. Followings are the summary of the result. 1. Conservative treatment was done in 52% and operative treatment in 48%. 2. Mean follow-up period was 1 year and 8 months. 3. The result of treatment was good or fair in 53% of conservative treatment group comparedto 71 in operative treatment group. 4. Primary total hip replacement was done in one case of bursting fracture combined with fracture of femur neck and the result was good. 5. Superior and bursting fractures showed the worst result(poor in 83%). 6. Degenerative arthritis with or without avascular necrosis was the most common complication (45 %) and it was more common in conservative treatment group (60 vs. 29%). 7. From above results it could be said that operative treatment in acetabular fractures, if carefully done with reasonable indications, would improve the result and decrease the rate of degenerative arthritis.

A 50-year-old female, who had been suffered from diabetes rielitus, showed typical cutaneous findinhs of dermatomyositis with only transient and mild proximal muscle weakness at sometime during the course of disease. She had Gottrons papules, Gottrons sign, heliotrope rash, macular violsceous erythema involving neck, anterior chest, back, extensor site of forearms and arms and dorsa of hands. However, he serum CPK, LDH and sGOP levels were within normal limits. Her fasting and 2 hours potprandial blood glucose levels were elevated. There were no histological abnormality in muscle biopsy. Histopathologic findigs of the skin lesion on her back were that of poikiloderma atrophicans vasculare. We diagnosed our patient as Rebeccas type 2 amyopathic dematomyositis which is chracterized by skin disease with subjective myalgias and musle weakness, but without laboratory evidence of muscle disease.

A case of circular eczematous dermatitis around seborrheic keratosis was presented. A 54-year-old man presented with two weeks history of a round pruritic eruption around a preexisting lesion of seborrheic keratosis. Microscopic findings showed central tumor nest composed mainly of basaloid cells with occasional spongtosis and exocytosis. A diffuse, dense, mononuclear cell infiltrate with increased contents of melanophages was seen beneath the tumor. The surrounding lesion of halo dermatitis showed mild dilatation of the capillaries and perivascular infiltration of mononuclear cells in the upper and mid-dermis. The lesion of halo dermatitis disappeared gradually over a three week period following excision of the central lesion. This peculiar phenomenon seemed to be different from that of Suttons halo nevus, and might be a manifestation of an eczematous condition which might have a dermatitis provoking factor.

Erythema multiforme can be induced by various causes, including infections like virus or fungus, drugs like sulfonamides and penicillins, internal malignences, connective tissue diseases, pregnancy, menstruation, and exoessive sun exposure ramoxone, one of the paraquat dichloride compounds, is the most commonly used weed-kiIler in Korea. It is sometimes used in suicides due to its fatal toxicity, and even weak transutaneous absorption can lead to death. Herein we report a case of erythema multiform in a 46-year-old man induced by accidental contact with the Gramoxone

Twenty-nail dystrophy is a rare entity in which all 20 nail are uniformly and simultaneously affected with excess longitudinal ridging and loss of luster. This condition is thought to be idiopathic but, many cases are associated with alopecia areata, lichen planus, psoriasis, and ichthyosis. In such cases, it has been hypothesized that immunplogical disorders could play a role in pathogenesis. A 29-year-old male patient presented with dystrophic nail chatge on his all finger and toe nails for 3 years. On phisical examination, all nails were uniformly affected with longitudinal ridging and loss of luster and all body hairs were lost. Thyroid scan showed a finding of chronic thyroiditis. Herein we report a case of twenty-nail dystrophy associated with chronic thyroiditis and alopecia areata.

There have been several reports that total knee arthroplasty(TKA) was most likely to survive successfully if the coronal tibiofemoral angle was close to 7 degree of valgus, the accepted normal. In order to know whether the postoperative coronal tibiofemoral angle influences the result of total knee arthroplasty, we examined the 152 TKA cases in 106 patients which had been performed at Department of Orthopaedic Surgery, Seoul National University Hospital from Jan. 1987 to Dec. 1991. In our series the average follow-up period was 31 months(range, 13 months to 75 months). Coronal tibiofemoral angles of all cases were checked on weight bearing anteroposterior plain X-rays and were divided into three groups(less than valgus 2° ; valgus 3° to 7° ; greater than valgus 8°). All cases were analyzed on the knee score of Hospital for Special Surgery and the American Knee Society total knee arthroplasty roentgenographic evaluation and scoring system and the cases with radiolucent lines wider than 2mm were checked. Three groups were analyzed comparatively with statistical means(Wilcoxon signed rank test, X² test). There were no significant differences in the clinical results of total knee arthroplasty according to the postoperative coronal tibiofemoral angle. Lateral subluxation of the patella occurred more frequently when the postoperative coronal tibiofemoral angle was above valgus 8°. In the tibial components of group lesser than valgus 2°, the frequency of radiolucent lines wider than 2mm was higher than those of other groups, but its significance should be examined through long term follow-up.

Herniated intervertebral disc(HIVD) of the lumbar spine has been known to be relatively uncommon in the teenager and frequently be associated with trauma. However, with the changing life style and increasing sports activities, and most of all, with the advent of new imaging modalities, the incidence seems to be increasing gradually. In order to define the characteristic pattern of HIVD of teenager in the era of MRI, and to clarify the associated lesions, such as apophyseal ring fractures, authors performed this retrospective study in 55 teenager patients with HIVD(77 discs), in which MRI was used as main diagnostic modality. The following results were obtained 1) The incidence of the HIVD in teenager was 9.6%(55 patients) of total HIVD patients(575 patients) for 4 years from December 1989 to December 1993. 2) According to MRI findings, HIVD of the teenager could be classified into 3 distinct patterns; simple HIVD, lumbar apophyseal ring fracture(LARF), and vertebral rim lesion. 3) In simple HIVD, as for the MRI classification, protruded type was most frequent type and there was no sequestered type 4) In LARF, the incidence was 14.4% of teenager's HIVD and posterocephalad margin of L5 was the most common site of involvement. 5) Exophytic bony protrusion from the posterior margin of vertebral body, which we called vertebral rim lesion, could be defined on MR sagittal view in 6 cases.

Although long-term studies of total knee arthroplasty(TKA) have confirmed reliable relief of pain and maintenance of function, survivorship at nine to ten years has been inconsistent with late component loosening being the most frequent mode of failure. Tibial component failure has been more frequent than failure of the femoral or patellar component in most TKA series. Encouraged by the early results of porous-ingrowh femoral and patellar components, and aware of retrieval studies showing poor bone ingrowth into tibial components, the “hybrid” method of fixation with an uncemented femoral component and a cemented tibial component, has been introduced and incorporated the potential advantages of both traditional fixation techniques. Between January 1987 and December 1991, forty-five “hybrid” TKAs(group I) were performed in degenerative arthritis and evaluated retrospectively in comparison with the results of nineteen noncemented porous-coated TKAs(group II) in degenerative arthritis. The average follow-up period was 31 months(range, 14 to 60 months) in group I and 26 months(range, 13 to 63 months) in group II. Using the knee rating scale of the Hospital for Special Surgery and the American Knee Society Roentgenographic Evaluation and Scoring System, clinical and radiological comparative study between two groups was performed. Pain scores, range of motion and HSS knee scores improved in both groups, but there was no significant difference between group I and group II(p>0.05). In both groups, the scores of radiolucent lines were significantly higher in zone 1 and 4 of A-P roentgenograph of the tibial component than in other zones(p < 0.05). The tibiofemoral angle was corrected from varus 2.7° to valgus 5.8° in group I and from varus 3.4° to valgus 4.6° in group II. There was no significant differences in component position and scores of radiolucnet lines between group I and group II. In conclusion, there were no significant differences in clinical and radiological results between the “hybrid” and the cementless groups. Results of this study suggest that both the hybrid fixation and the comentless techniques can reliably provide satisfactory clinical and radiological results in properly selected degenerative arthritis patients. But the final outcomes of this study need further evaluation through long term follow-up.
