Blade Plate による股関節圧迫固定術

抄録

We invented the K-U Compression Blade Plate for hip fusion, and tried to 13 cases with very good result. This plate was put on the anterior surface of the hip joint and had excellent immobilizing strength to the joint. Therefore the patient may ambulate earlier with this plate than other methods.
The skin incision of this procedure was followed by the Smith-Petersens method. Underlying sartorius and rectus femoris muscles were retracted medially, and tensor fasciae latae and vastus lateraliy muscles were retractcd laterally. The origins of the tensor fasciae latae and the gluteus medius and minimus muscles were separated from the crest of the ilium subperiosteally. Then incised the capsule followed by artificial dislocation of the head of femur.
After the cartilages of both acetabulum and head of femur were removed, the orgin of vastus intermedius muscle were separated partially for the purpose to put the blade plate anteriolly.
The blade was inserted at the point of antero-inferior iliac spine and directed to posteromedially in order to use most thick part of the iliac crest for better immobilization.
