The vertebrae in horses form a critical component of the equine skeletal system, providing structural support and facilitating movement. Horses possess a series of vertebrae categorized into five regions: cervical, thoracic, lumbar, sacral, and caudal. These vertebrae protect the spinal cord and serve as attachment points for muscles and ligaments, contributing to the horse's posture and locomotion. Variations in vertebral anatomy can influence a horse's performance and susceptibility to certain conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the anatomy, biomechanics, and clinical implications of vertebral health in horses.
Krunajević T, Bergsten G.The clinical and pathological details of a case of ataxia in a 3-month-old colt are described. A marked protrusion into the vertebral canal of the body of the 3rd cervical vertebra was observed. C and C were immovably joined so that the deformity could not be corrected by extension of the spinal column at this point. There was a compression of the spinal cord corresponding to the protrusion. The cause of this luxation could not be established. It may be assumed that the distortion was congenital, or caused by trauma at an early stage and that clinical symptoms could be observed only when, a ma...
Back pain is the cause of bad welfare in humans and animals. Although vertebral problems are regularly reported on riding horses, these problems are not always identified nor noticed enough to prevent these horses to be used for work. Results: Nineteen horses from two riding centres were submitted to chiropractic examinations performed by an experienced chiropractor and both horses' and riders' postures were observed during a riding lesson. The results show that 74% of horses were severely affected by vertebral problems, while only 26% were mildly or not affected. The degree of vertebral probl...
A 4-week old Quarter Horse filly was evaluated for abnormal gait and lateral deviation of the cervical spine. Physical examination findings prompted radiographs and computed tomography of the thoracic vertebral column which revealed hypoplasia of several thoracic vertebral bodies and resultant scoliosis of the thoracic vertebral column and deviation of the left and right hemithoraces and associated ribs. Collectively, radiography and computed tomography provided an accurate description of the vertebral malformations resulting in scoliosis in this foal.
Loder RT, Walker AL, Blakemore LC.Fractures often occur due to equestrian activities with injury patterns varying by age. The purpose of this study was to investigate in detail fracture patterns and associated demographics in children due to equine activities. Methods: The US National Electronic Injury Surveillance System was queried for all injuries with the consumer product code 1239 (horseback riding) from 2000 to 2023. Those <16 years old with fractures were extracted. Statistical analyses were performed with SUDAAN 11.0.01™ software to obtain national estimates. Results: There were an estimated 101,677 patients with a f...
Shokry M, Ali LB, El-Sharkawy M.Showjumping athletic horses are frequently affected by back pain, which in turn influences their performance and equestrian activities. Unassigned: The aim of the present study was to determine the etiological factors predisposing to back problems in show jumping horses and how to diagnose, and manage them. Unassigned: A total of 75 cases (45 geldings and 30 mares, aged between 8 and 23 years and weighing 420-550 Kg) with histories suggestive of back problems and low competitive ability as show jumping were used in this study. The evaluation of data was based on the inputs of case history, cli...
Patricio CR, Winter GHZ, Garbade P.Spinal articular dysfunction disrupts normal neural function and may lead to stiffness, pain or poor performance. Back pain is common in equine athletes, and it is a common complaint by horse owners requesting chiropractic evaluations. Objective: To describe the prevalence of spinal articular dysfunction in showjumping horses. Methods: Retrospective analysis of clinical records. Methods: Records from 3 years of examinations in horses, from beginners to high-performance levels. Each horse had 30 spinal segments evaluated for the presence of dysfunctional articulations. Exams were performed by...
Hellige M, Geburek F.Diagnostic imaging is an important part of the diagnostic approach in equine spinal ataxia especially with the cervical spine being commonly involved. The spinal cord may be affected by a variety of conditions including cervical vertebral malformations, osteoarthritis of the articular process joints or less commonly neoplasia. Advanced imaging techniques such as myelography are more accurate in diagnosing spinal cord compression and may be performed under general anesthesia in neutral, flexed and extended positions of the cervical spine. The use of ultrasound is non-invasive and allows ultraso...
Loder RT, Walker AL, Blakemore LC. Equestrian activities can result in spine injuries. Most studies are from single centers, and none use a national database. It was the purpose of this study to describe the demographics, injury mechanisms, and types of equestrian-associated spinal injuries using a US national ED database. The National Electronic Injury Surveillance System database was queried for equestrian-related spine injuries from 2000-2023. ED disposition was categorized as discharged or not discharged. Statistical analyses accounted for the weighted, stratified nature of the data to obtain national estimates. There we...
Hoogelander B, Frippiat T, Bergman HJ, Vanderperren K, van Veggel ECS.Thoracolumbar congenital abnormalities are considered rare in mature, performing horses. This case report describes a 14-year-old Welsh pony presented with marked epaxial muscle atrophy, mid-thoracic spinal pain, and stiffness, most pronounced during canter. The thoracic spine exhibited scoliosis, centered at T9-T10, and kyphosis. Radiography and postmortem computed tomography revealed complex congenital malformations of the thoracic vertebral column, including abnormal morphology of the T10-T12 vertebral bodies, partial vertebral fusion, a malformed spinous process, a malformed rib with assoc...
Strootmann T, Peter VG, Körner J.Anatomical variations of the caudal ventral lamina of the sixth cervical vertebra (C6), referred to as equine caudal cervical morphologic variations (ECCMV), and radiographic modelling of the caudal cervical articular process joints (APJ) are commonly identified in sport horses, yet their interrelationship and relevance for athletic performance remain controversial. This retrospective observational study aimed to determine the prevalence of ECCMV and APJ modelling in a clinically sound warmblood sport horse population, to evaluate a potential association and to assess if ECCMV affects competit...
