Fractures in horses refer to the disruption in the continuity of a bone, often resulting from trauma, excessive stress, or pathological conditions. These injuries can vary in severity, from simple, non-displaced fractures to complex, comminuted fractures involving multiple bone fragments. Fractures can affect any bone in a horse's body, but they are most commonly observed in the limbs due to the high mechanical loads these structures endure. Diagnosis typically involves clinical examination and imaging techniques such as radiography or ultrasound to assess the extent and nature of the fracture. Treatment strategies depend on the type and location of the fracture and may include rest, immobilization, surgical intervention, or a combination of these approaches. This page aggregates peer-reviewed research and scholarly articles focusing on the etiology, diagnosis, management, and outcomes of fractures in horses, providing insights into current veterinary practices and advancements in equine orthopedic care.
The research article describes the treatment, recovery process, and prognosis of a 2-month old Quarter Horse, who suffered from severe lameness in the left forelimb due to an avulsion-type fracture […]

Cordonnier T, Germon V, Lemé C, Jouve JL, Launay F, Pesenti S.Despite benefits in children, sport practice has been reported with higher risk of fractures. Our objective was to report the characteristics of sport-related fractures in children and to compare them to fractures sustained in a domestic context. Our hypothesis was that sports-related fractures more frequently required surgical treatment, and could therefore be considered more severe METHODS: We conducted a retrospective cohort study including patients under 16 years old, diagnosed with a fracture at the emergency department, excluding skull and face fractures. Demographic data, context of inj...
Stucki G, Valet S, Fuerst AE, Weisse B, Jackson MA.The aim of this study was to compare the strength (load at failure) and the number of cycles to failure of 3.5- and 4.0-mm cortical screw-bone constructs for repair of navicular bone fractures in horses.This was an in vitro biomechanical study that used a four-point bending apparatus to determine the load at failure of 3.5- and 4.0-mm cortical screw-bone constructs subjected to static and cyclic loading.In static testing, pairwise comparison of 4.0-mm cortical screw-bone constructs demonstrated significantly greater strength (mean increase: +16%, = 0.0135) compared with those in the 3.5-m...

Schild CO, Nyaoke A, Asin J, Henderson EE, Blea JA, Stover SM, Uzal FA.Radial fractures are relatively uncommon (0-1%) injuries in postmortem studies of racehorses, and few cases have been published. We describe here a series of 42 cases of radial fractures observed in California racehorses. Autopsy findings from all racehorses submitted for postmortem examination between 2006 July 1 and 2022 June 30 that had a recorded radial fracture were evaluated. We included 42 horses (30 Thoroughbreds, 12 Quarter Horses), most of which were 3-5-y-old. Catastrophic radial fracture was observed in 30 (71%) horses; in the remaining 12 (29%) horses, the fracture of the radius w...

Zhang Z, Yang Y, Ma Y, Mai Z, Fu H, Wang X, Cao X, Li T, Li J, Guo Q.With the growing popularity of equestrian sports, the incidence of athletic injuries in horses has also risen. Among these injuries, proximal sesamoid bone fracture (PSBF) and flexor tendinitis are particularly common in the forelimbs of sport horses and represent major causes of musculoskeletal impairment. A 5-year-old horse presented with obvious symptoms such as swelling at the left fetlock joint and metacarpal region after exercise. Through lameness assessment, diagnostic imaging, and hematological testing, the horse was diagnosed with PSBF complicated by flexor tendinitis. The affected ho...
Hall NP, Sweeney DM, Holmströem M, Kim W, Wang Y, Donahue KD, Palmer SE, Lambert DH, Bayly WM.To determine whether targeted lesion-specific algorithms developed from data collected with accelerometer-based inertial measurement units worn by racing Thoroughbreds could retrospectively identify horses at high risk of incurring forelimb condylar or proximal sesamoid fractures. Unassigned: Fracture-specific algorithms were generated from July 2021 to December 2024 with accelerometer data from 42,623 races by 15,755 horses, including 54 races by 23 horses that subsequently suffered condylar fractures and 90 races by 31 horses that later sustained proximal sesamoid fractures. Fracture-specifi...

Marques GF, Moorman VJ, Ellis KL, Perlini M, Edwards VL.To describe the long-term outcome of a horse that underwent a standing, ultrasound-guided, minimally invasive, biceps brachii tenotomy. Methods: Case report. Methods: A 17-year-old Tennessee Walking Horse gelding. Methods: The horse had a chronic, severe, lameness localized to the left shoulder region. Diagnostic imaging revealed fractures of the intermediate and lesser tubercles of the left humerus, biceps brachii (BB) tendinopathy, and bicipital bursitis. Conservative management was attempted, but lack of improvement prompted surgical intervention. An ultrasound-guided, minimally invasive, B...
Zedler S, Jukic C, van Eps A, Stefanovski D, Genton M, Rossignol F.To compare the biomechanical properties of a three-dimensional (3D) printed titanium plate and spacer (3DM) and a 4.5 mm broad locking compression plate (LCP) for intervertebral fusion of C4-C5 in the horse. Methods: Ex vivo experimental study. Methods: Twenty-four equine cadaveric cervical spines. Methods: Twenty-four cadaver equine cervical spines were randomly assigned to ventral intervertebral fusion with either 3DM (n = 12) or LCP (n = 12) at C4-C5.

Pan M, Malekipour F, Pivonka P, Morrice-West AV, Flegg JA, Whitton RC, Hitchens PL.Fractures of the distal limb in Thoroughbred racehorses primarily occur because of accumulation of bone microdamage from high-intensity training. Mathematical models of subchondral bone adaptation of the third metacarpal lateral condyles are capable of approximating existing data for Thoroughbred racehorses in training or at rest. To improve upon previous models, we added a dynamic resorption rate and microdamage accumulation and repair processes. Our ordinary differential equation model simulates the coupled processes of bone adaptation and microdamage accumulation, and is calibrated to data ...
