Abstract
|
|
|
We made a V-4 adM´
study on ten rabbits "for the purpose of reducing and. preventing the complications and sequales such as the delayed union and the aseptic necrosis of the head in the treatment of the femoral neck fractures. `Tbe ,midneck of the femur of each rabbit was experimentally fractured and was immobilized by the insertion of two K-wires into the fractured fragment. Then we made an Muscle Pedicle Bone Graft on - the area extending from the greater trochanter to the head of the femur inserting the muscle pediele bony fragment, Rectus femoris and Sartoris originated from middistance between Anterior Superior ´ Iliac Spine and Anterior Inferior Iliac Spine were also -detached -with -the underneath bone. The roentgenographic and microscopic findings ´at 6 th_ and $th weeks after operation, the results were so´satififactory´that we applied on it clinically.
The summary of the results were as follows.
1. Group of experimental rabbits.
1). Their was roentgenographic evidence that the fracture gap haa. disappeared -and the density of the grafts was never changed with the comparison to the other femoral head and neck.
2. Histological study, fracture line reveals complete bone union except the´-foci of ingrowing of chondrous tissue and fibous tissue.
2. Clinical application.
1) There was "roentgenographic evidence that complete bone naion at--the fracture site `arid no evidence of aseptic necrosis iof femoal head.
2) The patient was t;atry3ng -a :relatively normal activity without, the- limited ´ ge of ´motion of the hip-joint und:dthet"r(ocripl inns.
