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.

OBJECTIVE: Gait pattern in patients with lumbar degenerative kyphosis (LDK) is disturbed because trunk bends forward due to decreased lumbar lordosis. Surgical therapy in LDK is required when conservative management fails. We investigated kinematic and kinetic changes of the pelvis, hip, and knee joints on the sagittal plane in patients with LDK before and after operation. METHOD: Fifteen patients underwent operations between March 1999 and September 2003. Gait analysis was performed for all patients. RESULTS: Total lumbar lordotic angle increased from 10.50 degrees +/-11.22 degrees to 26.71 degrees +/-8.80 degrees postoperation. In gait analysis, anterior pelvic tilting angle increased from maximum 7.86 degrees +/-9.69 degrees, minimum 4.40 degrees +/-9.82 degrees to maximum 12.61 degrees +/-5.36 degrees, minimum 9.68 degrees +/-5.63 degrees (p<0.05). Maximum hip flexion angle changed from 31.39 degrees +/-11.71 degrees to 35.83 degrees +/-5.84 degrees (p<0.05). Maximum knee flexion angle in terminal stance phase decreased from 13.32 degrees +/-7.34 degrees to 8.30 degrees +/-6.38 degrees (p<0.05). CONCLUSION: After corrective operation, an increase of lumbar spine lordosis and anterior pelvic tilt with decrease of knee flexion were observed. However, an increase of maximum hip flexion secondary to increased anterior pelvic tilting influenced ambulation negatively. Therefore, stretching of the hip flexor and strengthening of the hip extensor are required before and after operation.

Endobronchial lipoma is a rare, benign neoplasm of the large bronchi, which makes up about 0.1 percent of all lung tumors. It can produce irreversible parenchymal lung damage or bronchiectasis if diagnosis and treatment are delayed. The treatment of endobronchial lipoma is early removal and surgical procedures depend on the status of distal parenchymal lung damage. We experienced a case of endobronchial lipoma in 53 year-old female patient, which caused total collapse of left lung and save left lung by enucleation of tumor via bronchotomy.

Cytomegalovirus (CMV) is the most common cause of life-threatening opportunistic viral infection in patients with acquired immunodeficiency syndrome (AIDS). However, CMV infection may occur in the immunocompetent individuals. CMV colitis has not been reported in a patient with splenectomy in Korea. Recently, we experienced a case of fatal CMV colitis in a patient with splenectomy. A 69-year-old man complained of bloody mucoid diarrhea and abdominal pain for 2 months. He had the splenectomy 6 months ago. CMV colitis was diagnosed by colonoscopy and pathologic examination. He died of sepsis in spite of antiviral ganciclovir therapy.

Congenital diaphragmatic eventration is defined as an abnormal elevation of the diaphragm resulting from developmental abnormality of muscle fibers during gestation. Differentiation between congenital diaphragmatic hernia (CDH) and eventration is very difficult but important for perinatal management and prognosis, because CDH is associated with higher perinatal and neonatal mortality. We describe a case that was initially diagnosed by prenatal sonography as a right CDH and later confirmed as a congenital diaphragmatic eventration after the delivery with a brief review of the literatures.
