Abstract
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.
Claims11
An orthopaedic device which comprises a waist band, two thigh bands and two leg bars in which one end of each of the leg bars is attached to a thigh band which is free to rotate about an axis perpendicular to the leg bar, the other end of each leg bar being freely rotatable about its axis and being held for rotation within a sleeve attached to the waist band, each sleeve being capable of being inclined downwards with respect to the plane of the waist band;
- and said leg bars make an obtuse angle with the axis of the sleeve whereby when worn the separation of leg bars is less when the legs are extended than when they are flexed and in which each leg bar is adapted so that when worn each leg bar is parallel to the leg of the wearer.
