In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues' mechanical strength or stability. Tissue fixation is a critical step in the preparation of histological sections, its broad objective being to preserve cells … WebDrill with the 2 mm drill bit a transverse hole through the spine of the scapula, at least 2-3 cm distal to the fracture. Then insert the wire through the transverse hole and then around the two K-wires in such a way that you will tighten simultaneously both the loop and the wires.
