Calcium misconceptions: In clinical work, it is often found that many patients with fractures, in order to grow their bones faster, often drink bone broth, even every day, as a panacea. This may be deeply misled by some popular ideas “eat what makes up for what” point of view. In addition, some people think that bone soup calcium. Also, some orthopedic doctors recommend eating some bone broth will promote bone healing. I do not know that the highest content of bone broth is phosphorus, not calcium. High phosphorus intake will greatly affect the body’s absorption of calcium, so drinking too much bone broth not only does not replenish calcium but also affects calcium absorption, which is not conducive to fracture healing. In addition, the fat content in bone broth is high, and drinking bone broth may mainly increase weight rather than supplement nutrition. I met a patient who had a femur fracture and had to drink bone broth every day for 1.5 years, but the fracture had not completely healed, and after advice, he stopped drinking bone broth and exercised moderately. Fracture healing conditions: 1. Good blood flow to the fracture site: directly related to the severity of the fracture and the fracture site. Also related to surgery, there are 2 misconceptions when it comes to surgery. One is that the better the fracture is the better the surgery is done, the better the alignment of the fracture is indeed the better it is for fracture healing, however, there are times (quite a few cases) when the fracture is not completely aligned, if the patient or family is very much looking forward to complete alignment, or if the doctor is obsessed with pursuing anatomical repositioning it will inevitably result in large soft tissue stripping of the fracture site, resulting in impaired blood flow to the fracture site and not easy The result is impaired blood flow to the fracture site, making it less likely to heal. The second misconception is that minimally invasive results are good. Minimally invasive is a relative concept, if the pursuit of the so-called minimally invasive, the incision is small, but the fracture is not well aligned, soft tissue cuttings; or repeatedly pulling the alignment, causing serious damage to the surrounding soft tissues surgery time is too long, although the wound is small but often outweighs the loss. 2, moderate compressive stress: some people believe that the fracture can not move, the affected limb should be stationary, rest. The scientific view is that early functional exercise should be carried out under good fracture fixation to protect adjacent joint function and avoid muscle atrophy and promote fracture healing. A moderate compressive stress at the fracture site is beneficial for fracture healing. A normal limb that is immobilized for 1-3 months can lead to disuse osteoporosis. Therefore, fracture patients, after surgery or good external fixation should be early functional exercise, including early muscle stretching exercise, medium-term joint flexion and extension, late weight-bearing functional exercise, etc. 3, good nutrition: should eat food rich in protein, fiber, calcium, and preferably some coarse grains.
