1.Preoperative Planning of Oblique Femoral Trochanteric Osteotomy by Geometric Analysis
The Journal of the Korean Orthopaedic Association 1995;30(5):1469-1480
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 28-year-old male patient is described who developed multiple erythematous nodules and papules on the face, upper chest, back, upper and lower extrimities, leading to extensive ia.filtration of the skin and lymph nodes. Histology from the involved lymph node and skin nodule revealed widely scattered patchy infiltration of abnormal. hyperchromatic polymorphous histiocytes in the dermis. The patient died at about 8 months after onset of the disease, in spite of antineoplastic treatment.

The Kato-Katz (KK) method is a well-known method of fecal examination for helminthiases. Its diagnostic sensitivity was found very high for clonorchiasis. The present study evaluated the correlation of Clonorchis sinensis egg counts by the KK method with those by direct smear and formalin-ether (FE) technique. The egg counts obtained by the KK method (Y) were correlated with the counts by direct smear (X) with the equation of Y = 659.4 + 0.266X (r2= 0.738), but not with those by the FE method. The present study demonstrated that the KK method and direct smear were useful for both qualitative and quantitative diagnosis of clonorchiasis, especially in the field.

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.

A clinical observation was made on 35 patients who were admitted to the Department of Orthopedic Sugery, Busan National University Hospital, 29 of whom had undergone operation from January 1979 to December 1983. The results obtained were as follows: 1. The peak incidence of age ranged from 51 to 60 years, which comprised 16 cases (45.7%) 2. The type of theDisease'were 15 cases with degenerative spinal stenosis, which comprised highest incidence, 11 cases with combined spinal stenosis, 6 cases with spondylolisthesis, 2 cases with idiopathic spinal stenosis and 1 case with iatrogenic spinal stenosis. 3. The duration of symptom before admisson ranged from 3 months to 20 years. Duration over 3 years comprised 54.3% of highest incidence. 4. The most common symptom on admission was pain in low back and leg, which comprised 31 cases (88.6%) and 4 cases had no specific neurologic deficit. 5. Myelogram was performed in 30 cases, C.T. scan in 7 cases and the most common myelographic finding was bilateral single level hour glass defect in 8 cases (26.7%). 6. Decompressive surgerys were done on 30 cases and post-operative results obtained were as follows: excellent in 11 cases (36.7%), good in 13 cases (43.3%), fair in 4 cases (13.3%) and poor in 2 cases (6.7%).

Image-guided localized, water-suppressed in vivo 1H MR spectroscopic studies were performed on the brain tumors in 3 patients. In all 3 patients, in vivo 1H MR spectra in brain neoplastic tissues revealed that the signal intensities of N-acetylaspartate (NAA) choline (Cho) resonances were decreased and increased, respectively, comparing with healthy normal tissue. A distinct lactate signal was identified in all three patients. A ratio that the observed metabolite alterations from localized, water-suppressed in vivo 1H MR spectroscopy can be useful as an index of brain tumors, and that the technique is clinically to highlight as one promising modalities in brain tumors for more accurate diagnosis.
