Oblique single-plane trochanteric osteotomy, in which an oblique cut is made through the femoral trochanteric area and the bony fragments are rotated at the face of the cut in direct contact with each other, allows simulatenous correction of the femoral neck-shaft angle, femoral anteversion as well as flexion/extension effect. Only approximate methods of calculating the correction effects of this procedure have been introduced. Considering unique spatial orientation of femoral neck, we developed a rigorous method to calculate preoperatively the obliquity of the single-plane osteotomy and the amount of rotation required to achieve the target femoral conformation, through geometric analysis. The correction effect by oblique trochanteric osteotomy on the geometry of proximal femur was dependent not only on the amount of change of the neck-shaft angle and femoral anteversion but also on the preoperative neck-shaft angle and femoral anteversion themselves. The flexion/extesion effect was determined by the direction of the correction and the preoperative neck orientation. Computer graphic simulation study confirmed the validity of this method. A program written in QBASIC was introduced to make this complex calculation method more useful in the clinical practice.

A case of stasis dermatitis with hepatomegaly is reported. The patient is 50 year old male. About 3 years ago a dark-brownish macule on the left shin was appeared with the severe itching sensation and spread to the margin with edema, ulceration, and appeared the varricous veins on the margin, Biopsy on the ulceration revealed the hemociderin deposition and fibrosis in the dermis. The physical examination revealed that the liver was enlarged 3cm, below the right costal margin and liver biopsy showed early cirrhotic change, but without impairment of liver function. He was treated with massage, elastic bandage for 2 weeks with good response.

We evaluated the scapular shape, dispiacement and rotation in 10 cases of Sprengel deformity using three-dimensional computed tomography in order to investigate its clinical usefulness. Standard views, including trunk posterior view, scapular true posterior view and medial view, were taken, and the 3-D image was rotated in three axes to visualize the omovertebral bony connection. In the trunk posterior view, the amount of superior displacement of the affected scapula was measured using the glenoid level as reference, and the rotational deformity by the tilting of the base of scapular spine. Scapular dysplasia was evaluated in the scapular true posterior and medial views. The presence, size, and anchoring points of omovertebral bone were assessed in various view points. There was a tendency of inverse correlation hetween superior displacement and rotational deformity of scapula. In most cases, the affected scapulae were convex at their medial borders and concave at their lateral borders, with increased width/height ratio. The anchoring point of omovertebral connection appeared to determine the scapular shape, level, and amount of rotation. Three-dimensional CT was helpful in preoperative planning.

OBJECTIVE: The safety and effectiveness of Guglielmi Detachable Coil(GDC) embolization for cerebral aneurysm has been well documented. However, domestically there are few reports. The purpose of this study is to analyze procedural complications that occurred during endovascular coilling performed for cerebral aneurysms retrospectively. METHODS: From January 1996 to December 2003, a total of 453 patients (484 aneurysms) who had undergone GDC embolization for cerebral aneurysm were selected. The aneurysms were classified according to rupture history, location, dome and neck size. Procedural complications such as aneurysmal rupture, thrombosis and occlusion of patent vessels due to coil escape were noted. RESULTS: Procedural complications occurred 49 cases (10.1%). Among these, there were 27 of procedure-related aneurysmal rupture (5.6%), 14 of thrombosis (2.9%), 8 of occlusion of patent vessels due to coil escape (1.7%). Death or severe neurological deficit were seen in 18 cases of procedure-related rupture, 9 cases of thrombosis and 4 cases of coil escape. Procedure-related mortality and morbidity rates for endovascular coiling were calculated to be 2.9% and 3.6% respectively. CONCLUSION: The potential complications associated with shape, size and relationship to parent vessels of each specific cerebral aneurysm must be considered carefully before treatment. In order to reduce complications, proper equipment, knowledge on the hemodynamics and vascular anatomy, and operator's expertise are desired.

Sixteen patients who underwent 18 modified Colonna capsular arthroplasty for old unreduced DDH1 between 1984 and 1992 were recalled and critically reviewed. The average age at operation was 11.5 years (range, 8.1 to 14.5 years). The average follow-up period was 7 years and 1 month (range, 5 to 13 years). All of the patients had pain or discomfort of the hip and limp. Femoral shortening was combined in all patients, and 13 hips required concurrent pelvic osteotomy (Chiari osteotomy in 5 hips Salter innominate osteotomy in 1 hips and Steel s osteotomy in 2 hips) or slotted shelf augmentation (5 hips) due to small and shallow acetabulum relative to the femoral head. In the remaining 5 hips which had thick medial acetabular wall acetabular reaming alone was performed. At the latest followup, 9 hips showed excellent 5, good; and 4, fair results according to the modified Harris hip score and IOWA hip score. In addition, all patients except one were satisfied with the outcome in terms of regaining hip stability and decrease in pain or discomfort and limp. Radiological evaluation revealed progressive, significant increase in size of the femoral head and sphericity improvement in 12 hips. The sphericity of the femoral head did not improve in other 2 hips. In the remaining 4 hips, in which preoperative femoral head shape was relatively aspherical, the sphericity worsened after affection of ischemic necrosis or osteoarthrosis. Complications included undisplaced femoral neck fracture during physiotherapy in 2, ischemic necrosis in 2, heterotropic ossification in 2, acetabular protrusio due to too much reaming in 3 hips, and residual subluxation requiring additional pelvic surgery in 2 hips, In conclusion, we believe that modified Colonna capsular arthroplasty with femoral shortening is valid, if properly done, in the reconsruction of painful hip with old unreduced DDH in late childhood and adolesence.
