Eighty primary Harris-Galante Porus (HGP) total hip replacements were performed at Severance Hospital from January 1986 to January 1989. A minimum of 18 months follow-up was available for 80 hips in 72 patients, whose mean age was fifty two years. The most common presenting diagnosis was avascular necrosis (47.5%) followed by fused hips (10%), tuberculosis (10%), rheumatoid arthritis (7.5%). Complications included three calcar cracks and two immediate dislocations and 6 cases of mild myositis ossificans. There were no infections and no revisions. The mean Harris hip score was 93 points (range, 74–100 points) at two years. The thigh pain was in nine patients (11 per cent) at one year and in three patients (3 per cent) at two years postoperatively. Radiographic analysis revealed that, a progressive radiodense femoral line developed in 21 hips (26 per cent); a progressive acetabular line in 3 hips (4 per cent); and decreased proximal femoral density in 28 hips (35 per cent). There were no position change of the acetabula and femoral compent. We conclude that the early overall clinical results of HGP total hip replacements are encouraging, at average 30 months. The prognostic significance of the radiographic changes such ar radiodense lines, the changes of the proximal femur and cortical thickening, have to be determined with longer follow-up. Long term follow-up of uncemented HGP total hip replacement is necessary to evaluate the efficacy of such implants.

This study consisted of 66 peritrochanteric fractures which were treated by the modified Gamma nail (Asian Pacific nail) from August 1993 to October 1995. Sixty-one intertrochanteric fractures and five subtrochanteric fractures were treated in our institution. Average length of follow-up was 15.0 months. Four patients died during follow-up. The results were as follows; Lag screws were ideally introduced in 55 (83%) cases. The mean length in lag screw sliding was 4.3 mm in stable trochanteric fractures and 5.7 mm in unstable ones. Fifty-one out of 62 patients (82%) were returned to their previous ambulatory status. Intraoperative complications were as follows; distal crack (3 cases); rotation of femoral head (2 cases); entry point crack (I case); medialization of proximal fragment (7 cases); and missing of the interlocking screw (1 case). All of these complications did not affect the outcome. All medial cortical gaps were closed after sliding of lag screws. Three distal cracks did not propagate to the shaft. Postoperative complications were a case of superior cut-out, and two second fractures after falls. Callus formed more early in the stable trochanteric fractures (5+/-2.1 weeks) than unstable fractures (7.3+/-2.1 weeks). It was statistically significant. Union time between stable and unstable trochanteric fractures was not statistically significant. In conclusion, the Asian Pacific (AP) nail could appropriately fix the osteoporotic peritrochanteric fractures in elderly patient. It could offer early rehabilitation to these patients and decrease the mortality and morbidity.

Mechanically the symphysis pubis serves to anchor the ends of the two weight bearing arches of the pubis-the femorosacral and ischiosacral arches. Under normal conditions it has been found to exceedingly resistant to separation. Sacroiliac strain is also uncommon because the sacroiliac ligaments are very strong and the movement which produce a torsion strain upon the joint is more likely to cause a strain of thinner capsular ligaments surrounding the small lumbosacral joints. We experienced a case of separation of the symphysis pubis and 2 cases of sacroiliac strain during and after spontaneous labor.

Ossification of the ligamentum flavum (OLF) has been recognised as a definite clinical entity as an ossification of the posterior longitudinal ligament. It has been known that the incidence of OLF is high in Japan and OLF usually occurs in the thoracic and lumbar region. Recently OLF has received considerable attention as a cause of myelopathy. OLF is quite distinct from “hypertrophy” of the ligamentum flvum. We experienced 2 cases of OLF with neurological symptom, which were treated by decompressive laminectomy and removal of the ossified ligamentum flavum. So remarkable symptomatic improvement was obtained.

PURPOSE: To evaluate the usefulness of percutaneous catheter drainage (PCD) in patients who have abdominal abscesses or fluid collections. MATERIALS AND METHODS: We performed PCD for 165 abscesses and fluid collections in 148 patients. The follow-up periods in these patients ranged from 15 days to 42 months (mean, 274 days). The lesion sites were subphrenic space in 46 cases, liver in 33, perihepatic space in 20, pancreas or peirpancreatic space in 14, pelvic cavity in 13, and retroperitoneum in 13. We evaluated the success, failure, and recurrence rates, the causes of failure or recurrence, the mean duration of drainage, and the complications of PCD. RESULTS: Of the 165 cases, one hundred-fifty nine(96.5%) were successfully cured, Although a partial success could be achieved, 2(1.2%) cases were failed and 4(2.4%) were recurred. Multiloculation or fistula formation were the main causes of the unsullessful cases. The duration of drainage rainged from 2 to 605 days (mean, 1 days). Complications occured in 12 cases(7%) during or after procedures, which included fever and chill in 7, transgression of pleura in 2, bowel perforation in 2, and bleeding through catheter in 1. CONCLUSION: PCD is an effective and safe method for various abdominal abscesses or fluid collections.

OBJECT: Accumulating evidence suggests a greater number of subcortical hyperintensities in the brain with bipolar disorder. We studied the Clinical correlates of subcortical hyperintensities on magnetic resonance imaging in patients with Bipolar Disorder. METHODS: Magnetic resonance images of the brain were obtained for 32 patients with bipolar disorder. The presence and location of hyperintensities were assessed. We compared clinical variables between with subcortical hyperintensities and patients without them. RESULTS: Seven Patients(21.8%) had subcortical hyperintensities, but among 8 patients who were or older, 5 patients(625) had them, Age and age of onset of patients with subcotical hyperintensities were significantly older than patients without them. Psychotic symptoms were more frequent in patients with hyperintensities. Patients without hyperintesities had more familial loading. CONCLUSION: Given the limitations of the study, our results should be seen as preliminary. This study, however, provides preliminary evidence supporting the notion that the onset, clinical feature and course of some bipolar disorders of late onset may be determined by underlying subcortical abnormalities, with such abnormalities being the consequence of factors related to aging or neurodegeneration(such as impaired cerebral circulation) rather than genetic factors which predispose to early-onset bipolar disorders.

PURPOSE: We report the results of embolization in 42 cases of brain arteriovenous malformation and discuss the technical problems. MATERIALS AND METHODS: Flow-guided microcatheter for the superselection of the feeding arteries and nbutyl cyanoacrylate as an embolic agent were used. Wire guided microcatheter and microparticle were used in two exceptional cases. As preembolization functional evaluation, 30--50mg of thiopental sodium solution was injected into the feeding arteries through superselected microcatheters in 40 cases with supratentorial lesions. RESULTS: There was no local arterial complication by injection of thiopental solution. Embolization caused a permanent neurologic deficit(mild to moderated hemiparesis) in 2 patients (4.8%) by a reflux of embolic agent or probable spasm of main arterial trunk. In 8 patients(19%), the AVMs were completely obliterated and 25 patients(60%) showed anglographic obliterations of 50--90% of the lesions. Embolization induced venous occlusion was demonstrated at post-embolization angiography in 6 patients, and 3 patients of them showed delayed and transient neurologic deficits. CONCLUSION: Embolization of cerebral AVM can be performed effectively and safely by a superselective method and appropriate functional evaluation. Superselective thiopental sodium injection is a safe and reliable test for the evaluation of local brain function before embolization.
