Untreated pseudoarthrosis can have adverse consequences such as localized pain, swelling, limited joint function and deformity. Pseudoarthrosis is a phenomenon in which the fracture site stops healing, the fracture ends harden, the bone marrow cavity becomes occluded, and the fracture site fails to connect even when immobilized for a long period of time. Pseudoarthrosis is caused by improper treatment of the fracture, displacement of the fracture, osteoporosis, etc. If the fracture is left untreated, the fracture site may be damaged or deformed. If left untreated, long-term pain and swelling at the fracture site, limitation of joint function, and even deformity will occur, seriously affecting the quality of life. Therefore, in daily life, if there is a pseudo joint formation, we should consult a doctor in time and have an operation as soon as possible, and after the operation, we should actively rehabilitate and exercise to promote the healing of the fracture.
