ABSTRACT
The preoperative measurement of adequate nail length is very important for femoral shaft fracture naiTing Operation. To reduce the disadvantages of scanography which are the fracture site pain, motion and radiation hazard, the simple external measurement method of intramedullary nail length was designated through this study. The fifty normal Korean whose bone growth v:as ceased were chosen for this study. And the lengths with the simple external measurement of thigh and scanogram of femur were compared at both side. The lateral roentgenographic view of femur was checked to analysis of anterior angulation at the proximal one third of femur was checked to analysis of anterior angulation at the proximal one third of femur. The following results were: 1. Femoral length was about 24% body height on an average. 2. The distance between the lower margin of the anterior superior iliac spine and the patellar upper pole (SPD) was equal to the distance between the tip of the greater trochanter and the cented of distal subchondral line. 3. Straight intramedullary nail length was 40 to 45 mm shorter than SPD. 4. The roentgenogram revealed that the femur took its anterior bowing by 9 degrees.

Eighteen cases of osteonecrosis of the femoral head associated with macromolecular polyvinylpyrrolidone (PVP) deposition were analysed on the basis of clinical, radiologic and pathologic features. The cases were observed during 8 years period from January, 1974 to December, 1981. The pathogenesis of the osteonecrosis of the femoral head due to PVP storage in reticuloendothelial system were discussed in detail. Parenteral administration of high-molecular PVP in repeated, long duration led to osteonecrosis of the femoral head. Storage of PVP in the histiocytes of the bone marrow resulted in osteonecrosis of the femoral head followed by microciculation disturbance. PVP-induced osteonecrosis were manifested as multiple foci of necrosis involving not only the femoral head, other long bones around joints, but also the visceral reticuloendo-thelial system characterized by infiltrates of histiocytes laden with PVP. The patients with PVP induced osteonecrosis complianed multiple joint pain in their early course of the disease. On roentgenogram, osteonecrosis were often noted in the hip, shoulder, knee, and ankle in order or frequency. Foamy histiocytes laden with PVP were characteristic on hematoxylin-eosin stain diagnostic on Weigert's elastica, phosphotungstic acid hematoxylin, and Congo red stains. As far as rationale of the treatment concerning a number of staging systems for Osteonecrosis, the choice of surgical procedures were similar to those given by W.F. Enneking et al. In the series, we have performed two hips in total surface replacement, 26 hips in total hip replacement mostly for 3rd generation-configuration of Charnley prosthesis. In addition, one case for free vascularized fibula graft and trans-trochanteric rotational osteotomy after Sugioka were also included for this study. The result of treatment was rather optimistic. However, complications have occured in 4 hips of 3 patients which required removal of whole prosthetic components. Therefore, we underwent revisional surgery in three out of four hips subsequently during the short post-poerative follow-up. These will be published in the future.
