Background

With the continuous updating of examination means and methods, the accuracy of bone tumor diagnosis is gradually improved, but a large part of tumors still have no typical imaging characteristics, so that diagnosis is difficult. The correct diagnosis of bone tumors requires three combinations of clinical, imaging and pathology. Among them, pathological diagnosis plays a key role in the selection of a treatment regimen. The method for obtaining the pathological diagnosis before the operation is biopsy, namely, a small amount of pathological tissues are obtained and sent to a pathology department, and the pathological diagnosis is obtained through microscopic observation or immunohistochemical methods. Biopsies are classified into closed needle biopsy, open biopsy and excisional biopsy, wherein needle biopsy and open biopsy are the main approaches for obtaining pathological diagnosis before operation.

In practical operation, bone tumor puncture has the possibility that lesion tissue is atypical due to small tissue of the obtained material, or accurate pathological diagnosis cannot be obtained due to the failure to accurately obtain tumor tissue. The open biopsy is a clear diagnosis of tumor tissue obtained by surgically cutting and exposing the exposed tumor tissue, and has disadvantages of great trauma, long time, and the influence of biopsy incision on the subsequent treatment because the tumor tissue needs to be obtained by surgical incision and exposure.
