An orthopaedic device which is suitable for the treatment or prevention of subluxation or dislocation of the hip joint is described. The device comprises a waist band, two thigh bands and two leg bars. Each leg bar is attached at one end to a thigh band which is free to rotate about an axis which is perpendicular to the leg bar. The other end of each leg bar is rotatably held in a sleeve attached to the waist band. Each sleeve is capable of being inclined downwards with respect to the plane of the waist band. The spacial relationship of the axis of the sleeve and the distal end of the leg bar is such that the device operates by maintaining the legs of the wearer in abduction that is appropriate to the extent of hip flexion by altering the separation of the legs in a smooth and controlled way during hip flexion.
