Article Synopsis
  • Radiological evaluations of the cervicothoracic junction in horses with neck-related clinical signs haven't been thoroughly analyzed before this study.
  • The research compared 127 control horses to 96 horses showing symptoms like neck pain, forelimb lameness, and proprioceptive ataxia, using standardized clinical and radiological methods.
  • Findings indicated that horses with clinical signs had a higher likelihood of severe articular process issues and spondylolisthesis at C7-T1, and showed various radiological abnormalities that stress the need for detailed assessments in symptomatic horses.

Background: There is controversy about the clinical relevance of congenital variants of the ventral laminae of the sixth (C6) and seventh (C7) cervical vertebrae and their relationship with other radiological abnormalities.

Objectives: To document the prevalence of congenital variants of C6 and C7 and that of other radiological abnormalities from C6 to the second thoracic vertebra (T2).

Study Design: Cross-sectional.

The Ridden Horse Pain Ethogram (RHpE) was developed to facilitate the identification of musculoskeletal pain. The aim of the current study was to collate behavioural data using the RHpE from horses at competitions assumed by their owners and/or riders to be fit for competition. The objectives were to quantify the frequency of occurrence of behaviours in pain-free horses and those with lameness or abnormalities of canter and to determine any differences between disciplines and levels of competition.

Background: Detailed descriptions of clinical signs associated with radiological findings of the caudal cervical vertebral column are not available.

Objectives/hypotheses: Describe the clinical features associated with neck pain or stiffness, neck-related thoracic limb lameness, proprioceptive ataxia consistent with a cervicothoracic spinal cord or nerve lesion, and their frequency of occurrence compared with control horses.

Animals: A total of 223 Warmblood horses.

There is a limited description of magnetic resonance imaging (MRI) and no information on computed tomographic (CT) findings in the fetlock of non-lame, non-racing sports horses. This study aimed to document comparative CT, MRI and radiographic findings in the metacarpophalangeal joints of showjumpers in full work. Clinical and gait assessments, low-field MRI, fan-beam CT and radiographic examinations of both metacarpophalangeal joints were performed on 31 showjumpers.
