OBJECTIVE To assess individual and combined associations of high-speed exercise and horseshoe characteristics with risk of forelimb proximal sesamoid bone fractures and proximal sesamoid bone midbody fractures in Thoroughbred racehorses. ANIMALS 269 deceased Thoroughbred racehorses. PROCEDURES A case-control study design was used to compare 121 horses with a fracture of at least 1 of 4 fore...

REASONS FOR PERFORMING STUDY Studies on arthroscopic removal of apical proximal sesamoid fracture fragments in Thoroughbred (TB) horses age > or = 2 years have reported a high success rate. However, there are no reports documenting the racing prognosis of TB horses that undergo such surgery as weanlings or yearlings. OBJECTIVES To describe the incidence of apical proximal sesamoid fractures i...

http://dx.doi.org/10.3415/VCOT-15-12-0202 Locking plates of various designs and specification are readily available commercially for fracture stabilization. All of these implants perform similarly, acting as angle stable internal fixators in regard to the plate-screw junction. There is a range of different mechanisms employed to achieve an angle stable locking connection between the plate and t...

The current study identified 124 lateral condylar fractures of the distal metacarpus or metatarsus over a 6-year period. Thirty were classified as displaced. Eight 30 displaced and 1/86 incomplete had concurrent sagittal axial fracture proximal sesamoid bone. A 20-degree DMPLO view is most sensitive radiographic projection to identify flexed demonstrates displacement complete fractures. Radiogr...

The radiographic evaluation of the fetlock joint as part of a lameness or prepurchase examination often reveals osteochondral fragmentation. These fragments can either be causing lameness or have no clinical importance at the time of examination. However, they can cause lameness at a later stage. An appropriate analysis of the situation requires a correct assessment of the fragment type and an ...

Cerveny C.: Osteometry of the Ossa Sesamoidea Phalangis Proximalis in Cattle (Bos primigenius f. taurus Linne 1758). Acta vet. Brno, 54, 1985: 119-128. The sesamoid bones of the proximal phalanges of the digits from 14 bovine females of the Bohemian Spotted cattle were subject to osteometric examination. Statistical significance of four characteristics was studied. There was no statistical sign...

A 10-year-old Thoroughbred mare was presented for lameness of the left hindlimb as a result of an apical fracture of the lateral proximal sesamoid bone. The mare was ultimately euthanased after suffering catastrophic fractures of the 3rd and 4th metatarsal bones of the contra-lateral hindlimb during an uncoordinated attempt to rise during recovery from general anaesthesia after undergoing arthr...

BACKGROUND Axial osteitis of the proximal sesamoid bones and desmitis of the intersesamoidean ligament has been described in Friesian horses as well as in other breeds. The objectives of this study were to review the outcome of clinical cases of this disease in Friesian horses and analyse the pathology of the bone-ligament interface. Case records of Friesian horses diagnosed with axial osteitis...

This study involves the evaluation of pre-purchase radiographic studies of South African Thoroughbred yearlings. Radiographic changes were recorded and compared with similar international studies. The study differs from other studies in that a lower prevalence of pedal osteitis (1.26%), dorsal osteochondral fragmentation of the metatarsophalangeal joint (1.60%), distal metacarpal sagittal ridge...
