The application of ordinary plaster cast after manipulative reduction of congenital dislocation of the hip may result in unfavorable complications such as atrophy and contruture of soft tissue followed by deformities of bone and incomplete formation of acetabulum. To prevent these complications the auther used fenestrated plaster cast, the technique of which is described in detailf in this paper.
After the application of the ordinary plaster cast in frog position a large opeing extending from groin to below knee in the antsrior aspect of each thigh. The opening allow some leg motion while holding the femoral head tight in the acetabulum. The allowance of the active movement in the hip is considered to give good results in avoiding the complications of the soft tissue ead osseous deformation. 95.4% of the studied 76 cassnshowed good results in view of functional recovery and 81.9% were resulted in excellent anatomical improvement. The allowance of some motion of the leg and femoral head in this type of fixation is suppoed to be responsible for the above good resulos.
