Weakness in lifting the hand of humeral tuberosity fracture may be caused by long-term braking of the shoulder joint or upward displacement of the fracture, which can be treated by hot compress, baking electricity, microwave instrument, etc., and assisted by functional exercise, and then manually reset and internally immobilized if necessary, or surgical reset can be chosen. If the fracture of the humerus tuberosity is weak in lifting the hand, it is generally considered that the activity of the shoulder joint is limited after the fracture, and the long-term inactivity has caused periarthritis. If the internal fixation is relatively stable, you can consider applying hot compresses, baking electricity, or microwave treatment, etc., and cooperate with the professional rehabilitation physician to carry out functional exercises to promote the recovery of the function of the shoulder joint. Note that the intensity of exercise should not be too great, so as not to affect the healing of the fracture. If the fracture of the humerus tuberosity is displaced upward, which triggers local pain and leads to the weakness of lifting the hand, it should be combined with the professional doctor’s opinion of treatment to carry out manual restoration and internal fixation, or you can choose the surgical restoration treatment. In the case of weak hand lifting of humerus major tuberosity fracture, it is recommended to go to the regular hospital as soon as possible for consultation and examination, to find the cause and take the next step of treatment in time.
