Desmopathy of the collateral ligaments of the equine distal interphalangeal joint – a prevalence in Poland between 2016-2019

Desmopathy of the collateral ligaments of the equine interphalangeal joint is caused by a combination of factors, including hoof shape, excessive loading and ground surface. This complex problem poses a diagnostic challenge due to the non-specificity of perineural analgesia and the limitations associated with the most popular imaging methods such as radiography and ultrasonography. The aim of this study was to retrospectively determine the prevalence of desmopathy of the collateral ligaments of the equine distal interphalangeal joint in Poland between 2016 and 2019, and to establish the frequency and type of the associated pathologies. Desmopathy of the collateral ligaments of the distal interphalangeal joint was diagnosed in 14% of 152 horses examined by magnetic resonance imaging (MRI). In 64% of the cases, other changes were observed in the equine digit, and in 36% of the cases, desmopathy was the only diagnosed problem. Desmopathy of the collateral ligaments is not a frequently reported pathology in the distal part of the equine limb. The diagnostic difficulties described in this article suggest that considerable caution should be exercised when formulating the final diagnosis, prognosis and treatment options.
