RESUMO

This study aims to evaluate the clinical signs and the histological findings compatible with the Degenerative Suspensory Ligament Desmopaty (DSLD), as reduction of the angles of metatarsophalangeal joints (MPJ) and the presence of proteoglycan accumulation in suspensory (SL) and nucal (NL) ligament of suspected animals. 108 animals (64 males and 44 females), mixedbreed and pure Brasileiro de Hipismo, from the Military Police of Minas Gerais (MPMG), had their MPJ angles measured. They were separated in tree groups, according to their age, that didnt show significant differences between their averages of MPJ angle values. Only tree animals (one from the 8 to twelve years and two from the >13 years), detached from the rest, presented MPJ angles lower than 1460. Such a reduced prevalence tax may be explained by the accurate selection of animals destined to reproduction. In addition, the presence of proteoglycans (PG) accumulation was evaluated in samples of suspensory ligaments (SL) (n=28) from animals of abattoir, considered suspicious, all mixed-breed Mangalarga Marchador. Although there were observed no significant difference between the groups, PG accumulation was predominant in the samples of SL, derived from animals of the 13 years group, demonstrating a relation between the presence of PG accumulation and advancing of age. In the same way, the NL (n=15) from the animals owned by MPMG, considered suspicious of DSLD, that were divided in two groups by age, didnt present a difference among the groups, beside the predominance in the group with more than 15 years. There was positive correlation between the PG presence in NL samples and the clinical signs of dorsal MPA angle reduction, proving the systemic nature of DSLD, as observed by Halper et al. (2006). The histological exam of the suspensory and the nuchal ligaments can be considered a complementary method of DSLD diagnosis
