The purpose of this study was to investigate the gaps of bone-acetabular component interface, the initial mechanical stability and the effects of adjuvant screw fixation in the press-fitted two different shaped porous-coated acetabular components. Semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup were press-fitted with or without adjuvant screw fixation in 40 bovine femur. The gaps of bone-implant interface were measured in each radiography of all specimen and axial compression tests and rotational stability tests were performed using servohydraulic tension-compression machine. There was significantly smaller gap at polar 1/3 region in the specimen implanted with Trilogy cup. But the adjuvant screw fixation did not affect the amount of gap. There was no significant statistical difference in axial load and rotational stability test in each situations of fixation. This study demonstrates that the initial mechanical stability is not influenced by the shape of semi-hemispherical Harris-Galante II cup and full hemispherical Trilogy cup and also independent of adjuvant screw fixation. But smaller gap of Trilogy cup at the polar 1/3 region indicates the possibility that less amout of wear debris of polyethylene or metal will be deposited and therefore less osteolysis or cup loosening will occur, but this hypothesis should be confirmed by the long-term clinical follow-up.

BACKGROUND: Three age-depedent clinical phases(infantile, childhood and adult phase) of atopic dermatitis(AD) were recognized. We think that for t he diagnosis of AD there seems to be some differences in minor clinical features of diagnosic significance according to each phase, yet only a few studies about them. OBJECTIVES: The purprrse of the present study was to evalute the diagnostic significance of total 39 minor clinical features of AD in Korean adolescenc and adult popluation, all but only skin were proposed by our previous study for Korean children. METHODS: The frequeney of 39 minor clinical features wistudied in 82 patients with typical AD compared to that in 109 control subjects. The age all studied individuals ranged from 13 to 42 years. Furthermore, some characteristic micro features of AD in them were compared with those from our previous study for Korean children. RESULTS: Twenty-seven minor features including xerosis, peifolhcular accentuation, frontal lichenification, anterior neck folds, eyelid eczema, Dennie-Mogan folds, auricular fissure/eczema, pityriasis alba, ventiral wrist eczema, infragluteal eczcm, sandpaper-like skin lesions on elbow/knee/lateral malleblus, white dermographism, scalaling, Hertoghes sign, orbital darkening, cheilitis, facial erythema/pallor, hyperlinear paln, ichthyosiform skin lesions, nipple eczema, nummular eczema, pompholyx, itchy hyperker totic lesions of dorsal hands, knuckle dermatitis of hands, hangnail, non-specific hand/foot dermatitis, chronic dermatophytosis were shown to be of much diagnostic signiic, nce(P<0.001). CONCLUSION: We think tiat 13 minor features such as Hert piges sign, cheilitis, facial erythe- mapallor, hyperlinear ichthyosiform skin lesions, ripile eczema, nummular eczema, pompholyx, itchy hyperkpratotic lesions of dorsal hands, kzukle dermatitis of hands, hangnail, non-specific hand/foot dermatitis, chronic dermato h tosis are specific for Korean adolescence and adult population with AD. Taken together, to propose that these 13 minor features be added to a gardeline for the large scale field sirvy on the incidence and prevalence of AD in the Korea adolescence and adult population.

BACKGROUND: For the diagnoais of atopic dermatitis(AD) an array of basic and minor clinical features proposed by Hanifin and Rajka were in common use. However, there have been some disputes in the diagnostic significance of minor clinical features of AD due to ethni. differences, variance in definitions, materisls and methods, OBJECTIVES: The purpose of the present study was to evaluate the dignostic significance of total 38 minor clinical features of AD in Korean children. Most of them wefe roposed by some authors in the literature and the remainder by ourselves based on our clinical experienes. METHODS: The frequency of these features was studied in 48 patieni s with typical AD compared to that in 89 control subjects. The age of all studied individuals ranged from 2 to 12 years. RESULTS: Thirteen of these was including xerosis, perifollicular acccntuation, frontal lichenification, anterior neck folds, eyelid eczema, Dennie-Morgan folds, auricular fiss are/eczema, pityriasis alba, vertral wrist eczema, infragluteal eczema, sandpaper-like skin lesion of yelbow/knee/lateral malleolus, white dermographism, and scalp scaling were shown to be of mueh diag nostic significance(P<0,001). CONCLUSION: We propose that above-mentioned 13 monor features may be a valuable guideline for the large scale field survey on the incidence and prevalence of AD in Korea children.

The bipolar hemiarthroplasty is one of the treatment methods of the avascular necrosis of the femoral head and the fracture of the femur neck. The mechanism of bipolar hemiarthroplasty is intended to distribute the forces at the site of the inner and outer articulation, and theoritically diminish acetabular wear and produce a painless arthroplasty. The authors analyzed motion of two components in 23 cases of the bipolar hemiarthroplasty, performed at the Department of Orthopaedic Surgery, Korea University Hospital, between January, 1985 and January, 1993 with average 47 months follow up(range 24 to 84 months). The results obtained were as follows: 1. In the motion of the two components, inner bearing motion was average 11.5 degrees(from 1 to 29 degrees) and outer bearing motion was average 21.4 degrees(from 3 to 45 degrees). 2. The inner bearing motion was highest at 12 months with average 16 degrees and outer bearing motion was lowest during the same period with average 15 degrees. During the follow up the inner bearing motion was decreased whereas outer bearing motion was increased. 3. The inner or outer bearing motion of bipolar component was no correlation with age, sex and clinical result.

Low back pain and radiating pain in the leg are the main symptoms of the spondylolisthesis and various surgical treatments are recommended after having enough conservative treatments. The spinal fusion in situ either posterior, posterolateral or anterior route is the usual method for symtomatic spondylolisthesis or to prevent progression of slipping but the neurogenic symptoms in the legs are not well solved, so the decompression procedures are necessary. The authors reviewed 26 cases of isthmic spondylolisthesis having low back pain and sciatica which are operated during the 10 years since 1973 at Fatima Hospital and the followings are obtained. 1. There were 15 males and 11 females with ages from 18 years to 63 years having average 40.1 years. 2. The displaced vertebrae were 5th lumbar in 18 and 4th lumbar in 8 cases and the degree of displacement was Grade I in 14, Grade II in 10, Grade III in 1 and no slipping in 1 case. 3. The types of surgery were decompression and H-graft in 22, simple posterior fusion in 3 and Gll's procedure in 1 case. 4. The laminas were considerably loose in all cases and there were small fibrous mass at the pars area in half of the cases. .5. The spine became very stable immediately after H-grafting and the intervertebral foramen became widened freeing nerve root. 6. Bony union obtained in 88% and satisfactory result in 85% at the follow-up from 6 months to 7 years and 2 months with average 1 year and 7 months. 7. The decompression is necessary for the radiating pain in the leg and H-grafting is satisfactory and simple procedure after decompression laminectomy.
