The reasons why fracture patients cannot have intercourse are as follows: 1. After the fracture, the stability of the fracture end should be maintained. Patients with upper limb fracture also need to maintain the stability of the fracture end, generally require patients to maintain the upper limb can not rotate, can not flexion and extension activities, patients can carry out muscle function exercises of the wrist joint, for the patient’s lower limb, generally require patients to maintain a position, can not change the position at will; 2, from the theory of Chinese medicine, the kidney is the main bone marrow, in the process of bone development and growth, the kidney plays a vital role. Therefore, patients with fractures should not have intercourse during the process of bone healing, because intercourse can easily lead to kidney essence deficiency, which can affect the growth of bone scabs at the fracture end and lead to delayed healing or even non-healing of the fracture. Especially in patients with lower limb fractures, the healing of the fracture end is slower because generally, the healing time of thigh fractures is 3-4 months. If the kidney essence is deficient for a long time it can easily lead to delayed healing of the fracture.
