Abstract

En bloc staining with basic fuchsin has become the method of choice to demonstrate bone microdamage produced in vivo. Several alterations have recently been made to the protocol. This technical note presents the new protocols, which include staining through a graded series of alcohols under vacuum, and eliminating the original evaporation stage in the staining protocol. Reasons for variations in staining quality can be related to inadequate dehydration, failure to stain under vacuum, the source of the basic fuchsin, or the solubility of basic fuchsin in water. The most common reasons for over- or understaining are the time left in stain, and the density of the bone. Limitations to the technique include the fact that probably not all cracks are stained by the technique, and the technique is not useful for studies that involve bone with highly variable densities in a single section.

    Fatigue loading induced damage was quantified through histological examination of microcracks in bone. For this, fatigue loaded as well as unloaded control samples were en-bloc stained in 1% basic fuchsin in ascending series of alcohols (80%, 90% and 100%) under 20-psi vacuum(Burr and Hooser, 1995). Further, bone samples were sectioned transversely into 200 µm thick sections using low speed diamond wafer saw and grounded to 100 µm thickness.

    Maxillae (n = 1 each group) were fixed in 70% ethyl alcohol for 3 days immediately after harvesting. The blocks were stained as a whole in 1% basic fuchsin hydrochloride in a graded series of alcohols under vacuum according to a standard protocol (Burr and Hooser, 1995). After staining, the blocks were embedded using methlyl methacrylate.
