Abstract: The paper by A Boyde and EC Firth published in the New Zealand Veterinary Journal 53, 123–132, 2005, entitled, “Musculoskeletal responses of 2-year-old Thoroughbred horses to early training. 8. Quantitative back-scattered electron scanning electron microscopy and confocal fluorescence microscopy of the epiphysis of the third metacarpal bone”, contained an error in the text on Page 124, where reference was made to Figure 2. There was also an error in the caption for Figure 2, and omission of labels on the figure. In the text and caption, “Slice A” and “Slice C” were transposed; Slice A denoted the dorsal slice, not the palmar slice, and Slice C denoted the palmar slice, not the dorsal slice. The correct text, figure and caption are: Limbs were removed at the abattoir after horses were euthanised, and the distal segments of the right Mc3 were frozen at –20°C until sectioned using a low-speed water-cooled diamond saw (LabCut; DR Bennett Ltd, London, UK). A special clamp was fabricated to hold the distal portion of Mc3. Each was first cut in the mediolateral (frontal) plane in the line of the centre of the shaft, to generate a 2.5-mm thick slice (Slice B). Two further 1.5- or 2-mm sections were cut perpendicular to the joint surface, the palmar piece (Slice C) inclined at 30–35° and the dorsal (Slice A) at 25° to the centre line, so as to pass through the centre of rotation of the joint and those regions of the condyles in which CT imaging in a companion study (Firth et al 2005) had shown the greatest densification in response to exercise (Figure 2).

Each was first cut in the mediolateral (frontal) plane in the line of the centre of the shaft, to generate a 2.5-mm thick slice (Slice B). Two further 1.5- or 2-mm sections were cut perpendicular to the joint surface, the palmar piece (Slice C) inclined at 30–35° and the dorsal (Slice A) at 25° to the centre line, so as to pass through the centre of rotation of the distal joint.
