“V” Shape Corrective Osteotomy of the Long Bone / 대한정형외과학회잡지

ABSTRACT

French method of wedge osteotomy has been widely used to correct the cubitus varus deformity, but it is difficult to correct the rotational deformity, gunstock deformity effectively and to fix the distal fragment rigidly because the supracondylar area of the humerus has an anatomical characteristic of short distance in A-P plane. We can design a new method of “V” shape osteotomy to correct the cubitus varus and apply this method to the deformities of the tibia and femur. Ten cases of “V” shape corrective osteotomy were performed in the Department of orthopedic Surgery, Kyung Hee University. Of these, 5 cases were cubitus varus deformities, 3 cases were deformities of tibia and 2 cases were deformities of femur. The results were obtained as follows. 1. The cubitus varus and gunstock deformities are corrected effectively without unnecessary bony loss. 2. The rotational deformity can be corrected in stable position due to the “V” shape contact surface. 3. The contact area is so wide and oblique that it may be ease to manage the distal fragment and we may expect good union process with early ROM exercise due to rigid fixation. 4. Additional change of the corrective angle can be possible. 5. This method is also effective for the correction of the deformity caused by partial epiphyseal closure of the long boen, using partial open wedge osteotomy.
