The severity of the left navicular fracture needs to be judged according to the local x-ray or CT examination. If the left navicular fracture is only a general linear fracture without obvious displacement, the general situation is not serious, and you can choose conservative treatment with plaster fixation. If the left navicular fracture is a serious comminuted fracture, even with the surrounding joint dislocation, which is a more serious injury, generally need to consider surgery. After the fracture of the left navicular bone, no matter it is surgery or conservative treatment, the recovery time is long, at least two to three months, so it is not possible to walk under weight at an early stage, otherwise it may lead to fracture displacement and affect the healing of the fracture, and at the same time, cooperate with blood circulation and blood stasis medicine such as blood circulation and pain relief capsule, and promote fracture healing medicine such as bone peptide tablets.
