An orthopedic apparatus for treating a child afflicted with the Legg Calv es Perthes disease. The apparatus includes a telescopic cross-bar adapted to be attached at each ends to the feet of a patient's resting on a bed, to keep his legs spread apart. A post upstands from the foot of the bed and carries pulleys; a rope is trained on the pulle ys and is connected at one end to the center of the cross-bar while a weight is attached to the other end of the rope. A constant pull is exerted on the patient's legs while the legs are ke pt spread apart. The amounts of pull and of leg spread are both adjustable. The present apparatus is destined to be used mainly at the child's home, but only shortly at the hospital, under the supervision of the parents. This apparatus is foldable and is easily carriable in a relatively small case.
