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.

We herein present a case of rare disease developed in a 43-year-old healthy woman. On her visit, we found several gray colored, well defined, pale, soft, wrinkled atrophic patches on the anterior portion of right upper chest area that is unusual location. The histologic findings showed typical features of lichen sclerosus et atrophicus.

The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

We report a case of morphea profunda in a 21-year-old male who had diffuse brown sclerotic plaques on his extremities. Laboratory findings showed peripheral eosinophilia and an increased titers for anti-DNA and anti-nuclear antibodies. Histopathologic findings showed diffuse fibrosis and a thickening of the lower dermis and subcutaneous tissue. He has been treated with hydroxychloroquine 400mg per day and the sclerosis of the skin improved.

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.

Plgmented villonodular synovitis is a benigh lesion that develops in joint lining and is characterized by an exuberant inflammation. Many authors have discussed etiology, clinical and radiological features, pathology and treatment regarding the disease. This occurs most commonly in the knee joint as a monoarticular proliferative process, but rarely in the hip joint. It is a nonneoplastic disease but may develop as an aggressive local process with bone and joint destruction. Sometimes clinician can not detect it in early time because of its nonspecific clinical findings and misdiagnose it as sarcomatous process. So, early diagnosis of hip joint involvement is necessary because destruction of the femoral head and acetabulum is the ultimate outcome if treatment is not intiated. We report two cases of pigmented villonodular synovitis involving the hip joint, which were diagnosed and treated in our department.
