The application provides a template image-based bone marrow abnormal chromosome detection method, device and medium. The method comprises: acquiring a bone marrow chromosome image to be detected; determining a target category of chromosomes in the bone marrow chromosome image through a trained and tested classification model; selecting a template image corresponding to the target category from a template library, wherein the template library stores a plurality of images representing normal bone marrow chromosomes; inputting the template image and the bone marrow chromosome image into a trained and tested difference analysis model to obtain a detection result, wherein the detection result comprises identification information representing whether the chromosomes in the bone marrow chromosome image are normal or abnormal, and an abnormal type corresponding to the abnormality when the chromosomes are abnormal. In this way, the accuracy of chromosome abnormality detection can be improved.

The application discloses a layered and blocked bone cement spacer and a preparation method thereof, and belongs to the technical field of orthopedic clinical treatment. After complete lesion removal, flushing and disinfection are completed, antibiotic bone cement is filled in a layered filling manner, S1: a first layer thin layer filling step: the prepared antibiotic bone cement is uniformly filled on the inner wall of a lesion gap in a thin layer smearing manner, the bone cement is fully attached to the bone wall in a soft pressing manner, a bone cement thin layer with a thickness of 2-3 mm is formed, the bone cement thin layer completely covers the inner wall of the lesion gap and is closely attached to the normal bone cortex, gaps are avoided, the layered filling manner of the thin layer and the block is adopted, the thin layer and the block are not completely fused, and slight gaps exist between the blocks, in a second operation, the thin layer can be first separated from an induction film by prying, and then the blocks are taken out one by one, without forcibly stripping, the difficulty of taking out is greatly reduced, the operation time is shortened, and the operation operation strength is reduced.
