Clinical, radiographic, ultrasonographic and computed tomographic features of nonseptic osteitis of the axial border of the proximal sesamoid bones

摘要: Reasons for performing study Lysis of the axial aspect equine proximal sesamoid bones (PSBs) is a rare condition reported to have septic or traumatic origins. Limited information exists regarding imaging nonseptic osteitis PSB. Objectives To report clinical, radiographic, ultrasonographic, computed tomographic and intra-arterial contrast-enhanced abnormalities in horses with Study design Retrospective clinical study. Methods Eighteen diagnosed border PSB between 2007 2012 were reviewed retrospectively. Case details, examination, intra-arterial/intra-articular features recorded, when available. Radiographic, ultrasonographic evaluations fetlock region had been performed on 18, 15 9 horses, respectively. The effect degree lysis grade duration lameness was determined. Results All chronic unilateral lameness, 4 forelimb 14 hindlimb signs. On radiographs, identified both PSBs one 3 horse no identified. osteolysis variable. Ultrasonography variably sized irregularities bone surface alteration echogenicity palmar/plantar ligament (PL). undergoing examination (n = 9) biaxial lysis. lesions significantly longer deeper images compared radiographic images. Intra-arterial tomography may reveal moderate marked contrast enhancement PL. There significant lameness. Conclusions Lesions can be using combination radiography ultrasonography. Computed provides additional extent pathology.
