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.

We studied the natural history of asymptomatic early avascular necrosis of the femoral head in forty-three patients(forty-three hips) who had been treated with arthroplasty due to progressed avascular necrosis of femoral head but had no symptoms in the other side. All initial lesions were classified with Ficat staging and International classification(ARCO). The duration until symptom onset and radiologic evidence of disease progression were evaluated. The average follow up period was over 37 months. Among forty-three hips, twenty-nine cases(67.4%) remained asymptomatic until last follow up but fourteen cases(32.6%) were symptomatic during the follow up, and twenty-six cases(60.5%) did not progress on the radiography but seventeen cases(39.5%) progressed to Ficat stage 3 or 4. Fifteen cases of IA, IIA, IB-cental and II B-central without lateral lesion did not occur symptom and didnt progress to Ficat stage 3 or 4 over a period of average 47 months(24-71 months). But fourteen cases of IB, IC, g B and II C progressed to Ficat stage 3 or 4 and they were all lateral lesion. These results suggest careful observation only can be done in the case of small involvement(less than 15%) and medial or central lesion relatively over a long period of time but for the large involvement(more than 30%) and especially lateral lesion, aggressive surgical treatment may be considered even though the early stage of disease for the prevention of progression. However it will need more period of time to accurately compare the results of various methods of treatment.

The authors reviewed both the clinical and radiographic results of 36 bipolar hemiarthroplasty using the porous-coated Harris-Galante uncemented femoral stem performed for avascular necrosis in 30 patients from January 1985 to June 1992. The average age was about 45.6 years and the average follow-up was fifty-four months. Clinical results by the Harris evaluation method were excellent in 33 cases, good in 2 cases, and fair in 1 case. The radiographic fixation of the femoral stem at final follow-up was bony ingrowth fixation in 31 cases, fibrous ingrowth fixation in 4 cases, and unstable fixation in 1 case. There was neither medial nor superior migration of the bipolar cup of more than two millimeters.

PURPOSE: We have evaluated the outcome of the operative treatment of Achilles tendon rupture and analyzed the prognostic factors related to the results. MATERIALS AND METHODS: Subjective assessment of symptoms, range of ankle motion and isokinetic ankle strength was performed on 50 patients during a 1-year follow up. We used a clinical scoring system reported by Leppilahti et al to evaluate the results. RESULTS: The overall results were excellent in 18 (36%), and good in 16 (32%), fair in 10 (20%), and poor in 6 (12%) cases. Lower activity level (P<0.001), presence of systemic disease (P<0.001), later return to physical exercise (P=0.044), and previous Achilles tendon symptoms (P=0.015) were associated with unsatisfactory strength results. An older age (P<0.001) and later return to strenuous activities (P=0.005) were associated with unsuccessful overall results. CONCLUSIONS: We think that a clinical scoring system, including subjective and objective assessment, is good protocol to find the prognostic factors related to the results after the operative treatment of Achilles tendon rupture. The patient group with poor prognostic factors present a challenge for rehabilitation.

Malformations of umbilicus are a feature of many dysmorphic syndromes and the measurement of periumbilical skin length should be considered as the basic step in the description of the umbilical malformations. So, we measured the periumbilical skin length in the 103 normal neonates and obtained the following results. 1) The means (+SD) of the periumbilical skin length were the 11.7mm (+3.0) in the cranial site and the 8.2mm (+2.5) in the caudal site, and the cranial length was 3.5mm longer than the caudal length. 2) No difference was observed between the male and female groups in the periumbilical skin length. 3) Age was the only statistically significant variable associated with the periumbilical skin length and it was observed that the periumbilical skin length decreased according to the advance of age (hour).

Endometrial papillary serous carcinoma (EPSC) is a distinct variant of endometrial adenocarcinoma that histologically resembles ovarian serous papillary adenocarcinoma and has an aggressive clinical course. Usually, the tumor is diagnosed at the advanced stage. The tumor has well confused with metastatic ovarian tumor of identical histology. Dignosis of EPSC should be considered when the cervico-vaginal smear reveals numerous papillary clusters of tumor cells with macronucleoli and psammoma bodies. Recently, we have experienced two cases of EPSC diagnosed on cervico-vaginal smears, which revealed characteristic cytologic features including numerous papillary clusters of tumor cells with macronucleoli. The cytologic diagnoses were confirmed on histologic sections.

Myocardial infarction is almost regularly associated with severe and widespread obstructive coronary artery disease. Recently, there have been some reports of myocardial infarction with normal of near normal coronary arteries on cineangiography. The following report concerns 6 cases (4% of a series of 142 consecutively studied patients with myocardial infarction) of myocardial infarction proved on clinical grounds with normal or near normal coronary arteries at coronary angiography obtained several months later. The clinical data was shown in Table 1 and Table 2. All 6 patients were male. Three were in the fifth, two in the sixth, and one in the seventh decade. Multiple risk factors were present in only one patient. Areas of localized dyskinesia or hypokinesia were demonstrated in five on the left ventricular cineangiography. The left ventricular end-diastolic pressure was greater than 12 mmHg in all 6 patients. One patient had hypertrophic cardiomyopathy and the remaining 5 patients had no underlying heart diseases. One patient had moderate congestive heart tailure. It is possible that prolonged, localized coronary artery spasm or platelet thrombi that subsequently resolved are a part of the pathogenic mechanism.
