轉子下切骨術の反省

抄録

It is said that subtrochanteric osteotomy is the treatment of choice for irreducible congenital and pathological dislocation of the hip joint, though it is a conservative treatment.
We examined 11 cases (14 hips) which had elapsed one year or more after operation, in making this report the length of follow-up has been too short. The results are not so good as we expected, particularly the flexion of several hips was restricted remarkarbly.
This bad mobility of the operated hips is due to the excessive anterior angulation at the site of osteotomy which is caused during the fixation in cast of paris and not due to the operative failure.
Therefore, by the use of internal fixation and postoperative lateral roentgenograms the fragments can be efficiently maintained in the desired proper position and the good mobility of the hip can be secured.
