Many patients feel good after the surgery, although the doctor repeatedly told the review and exercise matters when they were discharged, but many patients do not understand the importance of the doctor’s orders, and follow up on time as a wind in the ears, to a problem before they want to get up to review, but unfortunately it is too late to regret. Successful fracture surgery does not mean the end of treatment. As the saying goes, “seven points depend on the doctor, three points depend on maintenance”, the “maintenance” here can be understood as the post-operative nutritional intake, functional rehabilitation of the limb, exercise, etc. Many people do not pay attention to postoperative rehabilitation and exercise. After the completion of open internal fixation, or repositioning and external fixation in the hospital, the condition is stable, and patients are usually discharged in 4-7 days, and after discharge, some patients cannot follow up on time due to the distance from the hospital and inconvenience of travel, and exercise and rehabilitation according to their own imagination or the so-called “experience” of other patients. As a result of incorrect methods, many patients are left with many complications, suffering themselves and annoying their doctors. Common problems are: stiffness of the joint and inability to move, including the elbow joint when it is stiff in the extended position, inability to comb the hair and eat, with serious consequences. Upper limb fractures, including: scapula fracture, clavicle fracture, humerus fracture (including proximal humerus, humeral stem and humeral condyle fracture), ulnar radius fracture, wrist fracture and hand fracture, etc. The postoperative exercise mainly includes two aspects: 1. muscle contraction exercise In the early postoperative period (within 1 week), due to the wound pain, the movement of the joint is difficult, at this time, the patient should strengthen the contraction exercise of the muscle tissue of the upper limb without moving the joint. This contraction exercise can prevent disuse atrophy of muscle tissue, promote blood circulation of muscle tissue, prevent edema formation and promote the decreasing of edema, and prevent thrombus formation. In the middle and late postoperative period (after 1 week postoperatively), the extension and flexion exercises of all movable joints should be started except for the fixed joints or the joints that cannot be moved as explained by the doctor. Frequency of muscle contraction exercise: 10-20 minutes each time, the number of activities per day is not limited, in order not to fatigue. 2.Functional exercise of joints The contraction exercise of muscles is to maintain the power of muscles, while the function of joints is to complete the pivot of fine movements of upper limbs. If the joints are stiff due to long-term inactivity after surgery due to fear of pain, the consequences are serious and the limb becomes a useless and useless limb. In the early postoperative period (within one week), with oral pain medication, or with the guidance of a rehabilitation physician, and with the consent of the surgeon, functional exercises for extension and flexion of the unoperated fixed joint should be performed as early as possible. For example, for humeral stem fractures, functional exercises for extension and flexion of the shoulder and elbow joints should be performed as early as possible after surgery; for joints at distant sites from surgery, such as the wrist and small joints of the hand, activities can be performed immediately after postoperative anesthesia wears off. After 1 week postoperatively, the joints near the fracture site should start functional exercises of extension and flexion as far as possible. Exercise method: When extending and flexing the joint, each activity should be extended and flexed to the maximum range that you can do, not repeatedly in a very small range, and such repeated activities in a small range are meaningless. Each activity exercise should make the range of motion increased. Frequency of daily exercise: 20-30 minutes each time, no less than 3-6 times a day. Timely follow-up at the hospital No matter how effective the patient exercises by himself at home, after all, he is not a professional and cannot guarantee the safety and effectiveness of the exercise; some patients may also have various adverse complications for various reasons, which may seriously endanger the limb function or even the life of the patient. Therefore, it is very important to go to the hospital for timely review after surgery according to the doctor’s prescription, to carry out safe exercise under the guidance of the doctor, to detect adverse reactions or complications in time, and to carry out timely treatment as early as possible. After all, it is never too late to mend the fold.
