The aim of this study was to evaluate the different response of first phalanx cortical bone to training between the left and right forelimb in a group of Thoroughbred racehorses. Lateromedial and dorsopalmar views of each metacarpophalangeal joints were carried out before and at 1 year after the start of training for racing. The thickness of dorsal (DCP), palmar (PCP), lateral (LCP) and medial (MCP) cortex and width and thickness of medulla of the first phalanx (PI) were measured. Some ratios were calculated to remove the effect of differences in bone size between horses. The preliminary result showed no changes of cortical bone in response to training but there was a difference of palmar cortex between left and right forelimbs since beginning of the study: palmar cortex of the right forelimbs resulted thicker than left legs. PI bone deposition is different between right and left forelimbs probably as consequences of different strains patterns.

Abstract
The aim of this study was to evaluate the different response of first phalanx cortical bone to training between the left and right forelimb in a group of Thoroughbred racehorses. Lateromedial and dorsopalmar views of each metacarpophalangeal joints were carried out before and at 1 year after the start of training for racing. The thickness of dorsal (DCP), palmar (PCP), lateral (LCP) and medial (MCP) cortex and width and thickness of medulla of the first phalanx (PI) were measured. Some ratios were calculated to remove the effect of differences in bone size between horses. The preliminary result showed no changes of cortical bone in response to training but there was a difference of palmar cortex between left and right forelimbs since beginning of the study: palmar cortex of the right forelimbs resulted thicker than left legs. PI bone deposition is different between right and left forelimbs probably as consequences of different strains patterns.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
