Purpose: To investigate the extent of bone ingrowth into the porous-coated acetabular cups as well as the factors that correlated with bone ingrowth in total hip arthroplasty. Materials and Methods: Thirty six Harris-Galante porous-coated acetabular cups that were retrieved through revision surgery were examined in this study. Acetabular cups retrieved due to infection or severely destroyed cups (ed note: severe what?) were excluded. The extent of bone ingrowth into the acetabular cups was grossly measured, and its correlation with the variables including age, gender, weight, height, the duration of fixation, size, number of screws, inclination and anteversion was statistically analyzed. Results: The mean proportion of bone ingrowth was 52.9 21.9%(2~90%) and less than 30% in three cups(8.3%). The pattern and the location of bone ingrowth were not consistent. There was no correlation between the extent of bone ingrowth and age, gender, weight, height, the duration of fixation, cup size, number of screws, size, inclination and anteversion. Conclusion: Harris-Galante porous-coated acetabular cups showed satisfactory bone ingrowth regardless of the variables associated with the demographic or surgical conditions. Surface treatments with a fiber-metal porouscoating appears to be suitable for cementless acetabular cups in terms of the long term results.

Masson's hemangioma is a rare benign vascualr condition with a papillary intravascular endothelial proliferation which may appear either as aprimary form or as a secondary form in a pre-existing vascular process.CT and angiographic features of 2 cases with Masson's hemangioma were presented. Both of them were locatedextra-axially in the posterior fossa. CT findings were not specific in both cases: One showed homogeneously enhancing mass, simulating meningioma. And the other demonstrated a multiolocular rim enhancing mass. However, the angiographic features were rather characteristic; Both cases showed persistent vascular poolings of contrast mediawhich were supplied form the meningeal vessels. Angiographic differential diagnosis of similar lesions in theposterior fossa is discussed.

We present a patient who developed a pseudolymphoma after ear piercing. A patch test showed gold sensitivity. Therefore, long standing dermal exposure to gold from a pierced-type earring might have produced the patient's disease. This patient did not respond to an intralesional steroid injection and was finally treated with a complete resection of the lesion. It is proposed that every patient with a hyperplastic lesion in the ear lobe should be taken a biopsy in order to rule out the possibility of a pseudolymphoma. When a pseudolymphoma develops in the ear lobe, a complete surgical excision could be the treatment of choice, especially for the prevention of recurrence.

PURPOSE: We studied results of the communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate in the elderly. MATERIALS AND METHODS: We studied 29 cases of communited distal radius fracture treated with allogenic cancellous bone graft and volar locking plate from April 2009 to April 2013. Fracture was classified according to AO/OTA classification. Postoperative clinical evaluation was performed with measurement of wrist range of motion (ROM) at last follow-up, modified Mayo wrist scoring system (MMWS), and visual analogue pain scale (VAS). Radiologic evaluation was performed with measurement of radial length on immediate postoperation and last follow-up, radial inclination, volar tilt and ulnar variance checked at the last follow-up using Sarmiento criteria. RESULTS: Using the MMWS, 13 cases were classified as 'good', 10 'fair', and 5 'normal'. The average wrist ROM was 88.5% for flexion, 92.2% for extension, 90.5% for adduction, and 94.0% for abduction. The average VAS was 1.7. On the last follow-up, average radius length, radial inclination and volar tilt did not show statistically significant improvement (p>0.05) compared to immediate post operation measurements, and according to Sarmiento criteria, 5 cases were classified as 'good', 14 'fair', and 7 'normal'. CONCLUSION: Treatment of severe communited distal radius fracture accompanied by bone defect with volar locking plate and allogenic cancellous bone graft is a satisfying and effective treatment method in the elderly.

Skull base surgery has developed through the evolution of imaging, anatomic research, surgical approach and reconstructive techniques. The basic disciplines of approaching skull base lesions are provide direct vision, minimizing brain retraction, excellent exposure and minimal blood loss. The focus of this report is to review the advantages of skull base approach in our cases and suggest some indications. We experienced 20 cases of skull base surgery by a team approach consisting of a neurosurgeon and plastic surgeon. The surgical approach were supraorbital osteotomy(5 case), orbitozygomatic osteotomy(8 case), orbitozygomaticoglenoid osteotomy (5 case ) and orbitozygomaticoglenoidocondylar osteotomy (2 case). In our experience, these approaches provided excellent exposure of the lesion, direct access to lesions and minimal brain retraction thereby better outcome.

It is well known that the cell type and histopathological grading of gliomas correlate well with clinicalcourse and prognosis. Therefore, it is tempting to set certain criteria that could predict the histopathologiccharacteristics of the gliomas before the surgical intervention. With a total of 56 cases of gliomas which wereverified histopathologically in Seoul National University Hospital between July 1978 and May 1983, a statisticalanalysis of the computed tomographic findings was done with the particular emphasis on the correlation withhistopatholoigcal features. The results are as follows; 1. The calcification is observed in 27 cases (48.2%) intotal: in 20 cases (62.5%) among low grade group, in 6 cases (46.1%) among high grade group and in 1 case (9.1%)among glioblastoma multiformed group respectively. 2. The mass effect, especially surrounding low densitycorrelates well with the grade of malignancy. 3. The contrast enhancement is observed in 43 cases (76.8%). Thepattern of enhancement provides clues for the assessment of cell type and grade with fair degree of reliability.Among low grade group, 10 cases (31.3%) show no enhancement and 10 cases show solid enhancement. Among high gradegroup, 6 cases (46.8%) show solid enhancement and nodular or ring enhancement are not observed. Among glioblastomamlultiform group, 8 cases (72.7%) show characteristic thick irregular ring enhancement. 4. Plain CT densities arenot useful in differentiating each group in statistically significant level. 5. Neither the margin of the mass northe degree of contrast enhancement contributes for the differentiation of each group. 6. Summarizing the abovementioned findings it is concluded that CT is very helpful in differentiating the gliomas with regard tohistopathological cell type and the grade of malignancy as well.

This study was undertaken to examine the possibility of predicting the stage of brain abscess presoperatively,which may markedly influence on the decision how to manage the patients suffering from intracerebral abscesses. Atotal of 17 patients with brain abscesses, who were treated with surgery and diagnosed pathologically, wereretrospectively analyzied with particular attention to the correlation of CT and histopathologic findings. Wefound that preoperative CT findings could not provede any possibility on the decision of abscess staging.Therefore, we suggest that the sequential CT scans should be done in patients with susupectd brain abscess forevaluation of abscess staging.

Neurenteric cyst is an extremely rare developmental cyst of the central nervous system. It is lined withintestinal epithelium and is usually found in the subarachnoid space of the cervical and thoracic spine. We reporta case of intracranial neurenteric cyst in a 40-year-old man, and describe the MRI findings. This modality showeda large cyst, ventral to the pons and extending bilaterally to the cerebellopontine angles and craniovertebraljunction;its signal was hyperintense on both T-1and T2-weighted images and there is no enhancement on postcontrastT1-weighted images.
