Tendinose do supra-espinhoso em cães

Abstract

ResumoA tendinose do supra-espinhoso é uma desordem recentemente relatada em cães e bem documentada em seres humanos, espécie na qual representa 51% das causas de alteração na articulação do ombro. Em cães, a afecção pode levar à dor na articulação acometida e claudicação ou permanecer assintomática. O significado clínico do problema ainda não foi definido na espécie canina e parece ser subestimado. O objetivo deste trabalho é discorrer sobre as possíveis etiologias desta tendinopatia e principais métodos diagnósticos, bem como abordar as terapias mais aplicadas atualmente em medicina veterinária, atentando ao clínico sobre as características da doença e a importância de incluí-la no diagnóstico diferencial de causas de dor e claudicação do membro anterior em cães. Palavras-chave: Tendinose., tendão supra-espinhoso, cão AbstractSupraspinatus tendinosis was recently reported in dogs but it is a well-documented disorder in human beings, specie in which is considered the cause of pain and dysfunction in 51% of cases of shoulder problems. It can cause pain and lameness or be asymptomatic in dogs. The clinical relevance in canine specie is unclear and seems to be underestimated. The aim of this paper is to review the possible etiologies involved in this tendinopathy, the main diagnostic methods applied and actual options of therapies in veterinary medicine. Simultaneously, call the clinicians attention to this disorder as differential diagnosis for forelimb pain and lameness diseases.

Diagnostic ultrasonography of the shoulder in dogs – scan techniques and common findings

“…Bone alterations, such as fractures and dislocations, are easily identified on radiographic evaluation. Alterations of the soft tissues involved in stabilizing the joint, such as tendonitis and muscle contractures, among others, are rarely identified in radiographic studies and require additional imaging techniques to obtain a diagnosis GERWING, 2001;MISTIERI, 2008;MISTIERI et al, 2012;SILVA et al, 2013).…”

“…For its assessment, the shoulder should be kept in an anatomical position, with an approximately 135 o flexion, and slightly rotated externally (LAFUENTE et al, 2009;MISTIERI, 2008). Although it does not cause discomfort, anesthesia is performed because the bicipital tendon is simultaneously evaluated in the same procedure, as retrospective studies have shown the relationship between the presence of large calcifications on the supraspinous tendon and bicipital tenosynovitis (MISTIERI, 2008;MURPHY et al, 2008).…”

“…An ultrasound examination of this muscle is commonly indicated after radiographic findings of calcified structures in the region of its insertion into the greater tubercle of the humerus (MISTIERI, 2008;MISTIERI et al, 2012).…”

“…When pain is present in the shoulder region, particularly due to numerous soft tissue structures that may be affected and the limitations of radiographic examinations, the diagnosis tends to be compromised when other imaging techniques are not applied (MISTIERI et al, 2009;SILVA et al, 2013). In this context, diagnostic ultrasonography has been widely used in human orthopedic examinations since the 1970s (TEEFEY et al, 2000).…”
