As is clear from the above, in the treatment instrument 1, the femoral gripping means 4 is connected to the support rod 5 by the universal joint 6 so as to be rotatable in all directions around the fulcrum O. With this principle, not only can the hip dislocation of the patient be reduced by the open and displaced position by fitting into the acetabulum, but the reduction can be achieved while leaving the thigh A2 with the required freedom of movement even after the reduction. Since it is possible to stabilize the position, the pain on the patient A can be reduced.
Further, the entire treatment instrument 1 can be downsized, and the structure, operation and adjustment can be simplified.

Since the universal joint 6 is provided with the locking means 46, after the reduction, the locking means 46 locks the thigh gripping means 4 with respect to the support rod 5, thereby fixing the thigh A2 and reducing the thigh for a required period. You can maintain your position and achieve stability.
Further, by releasing the locking means 46, the restraint of the thigh A2 can be released, and the thigh A2 can be moved within a limited range, thereby reducing the pain to the patient A. it can.

Since the universal joint 6 is a spherical joint, the structure of the universal joint 6 can be simplified.
