The utility model provides an adjustable aluminum assembled clamp plate, consisting of a long aluminum plate, a big-end pressure pad and adhesive straps. The adjustable aluminum assembled clamp plate is characterized in that one end of the long aluminum plate is straight, and the other end thereof is arc; the big-end pressure pad takes the shape of a right angle, one surface thereof is adhered on the aluminum plate, and the other surface thereof is attached with an inner liner pad and is adhered on muscle; a groove is arranged between the two surfaces of the big-end pressure pad; and four pairs of adhesive straps are respectively fixed outside the aluminum plate and the big-end pressure pad. The long aluminum plate is clamped in the groove of the big-end pressure pad, and the position of the long aluminum plate can be adjusted backwards and forwards. When the clamp plate is in use, after pollicization by means of massage, the position of the big-end pressure pad is adjusted firstly according to the thumb of a patient, the length of a first metacarpale and a fracture position, and secondly, the adhesive straps are used for fixing the first finger bone of the thumb, the base of the first metacarpale, the wrist and the tail part of the aluminum plate. The arc part is the aluminum plate which has a certain plasticity and a properly changeable angle so as to better lead the back of the tumble to stretch, reliably fix the aluminum plate at a radial wrist joint; and the big-end pressure pad is effectively pressed at the base of the first metacarpale to adhere the adhesive straps in sequence without influencing the activity of the distal thumb and the function of the elbow joint.
