Why is it important to perform functional exercises after a fracture? 1. To promote swelling reduction and prevent joint adhesions and stiffness. After a fracture, the soft tissues at the fracture site generally have different degrees of bleeding and edema, and a lump will appear in the injured limb. If the lump is not eliminated in time, it will lead to adhesions and even stiffening of the corresponding soft tissues. Such adhesions can also occur within the muscle and tendon, between the tendon and synovium, and within the joint, thus affecting the function of muscle contraction. Therefore, after a fracture, many people feel that the joint around the fracture is not as mobile as before, and some even swell and become deformed. This can be avoided through functional exercise. 2.Promote fracture healing. Through functional exercise, the muscles of the injured limb are repeatedly stretched and contracted, which can strengthen the longitudinal compression of the fracture, make the fracture gap smaller and the fracture part more stable, improve the nutrition of the fracture part and promote the healing of the fracture. Functional exercises can also correct minor fracture misalignment, which is also conducive to the healing of the fracture. 3.Prevent thrombosis. In patients with long-term bedridden fractures, the blood circulation slows down due to the lack of muscle stretching and contraction, which makes it easy to form thrombus when the blood flows slowly in the damaged blood vessels. Small thrombus can dissolve on its own, but if the thrombus is larger, it comes off from the blood vessel wall and enters the systemic circulation with the blood, which can lead to infarction of the heart, brain, lungs and other important organs, and even cause sudden death. Through functional exercise, the elasticity of the blood vessel wall around the injury can be enhanced, so that the blood circulation can be smooth and thrombosis can be prevented. How to perform functional exercise according to the fracture healing situation? Clinically, the exercise of fracture can be divided into early, middle and late stages according to the postoperative recovery of fracture. 1. In the early stage, within 1-2 weeks after fracture, functional exercise is mainly based on the active stretching and contraction of the affected limb, and the upper and lower joints of the fracture are temporarily inactive. The purpose is to promote blood circulation of the affected limb, eliminate swelling and prevent muscle atrophy. 2. The middle stage is 2 weeks after the fracture, during which the upper and lower joints of the fracture start to move. The purpose is to prevent muscle atrophy and joint stiffness. 3.Late stage fracture has reached the clinical healing standard and the external factor has been removed. In this period, continue to strengthen the activities of the joints around the fracture and the whole body to promote the recovery of joint range of motion and muscle strength. What should I pay attention to in the exercise process? 1. Concentrate on even inhalation and accurate movements, do not be too violent. 2.Progressive. Gradually increase the range of motion and time according to the healing of the fracture, so as not to feel fatigue and not to aggravate the pain of the fracture site. Strictly limit the movements that are not conducive to fracture healing, such as rotational activities of forearm fracture; prevent slipping, bruising, twisting, etc. when exercising the weight-bearing limb of lower limb fracture. 3. Perseverance. During hospitalization, you should actively cooperate with the medical staff to learn and master the exercise essentials, and after discharge, you should still insist on exercising until the function is fully recovered.
