Treatment of fractures of the distal radius and ulna in toy breed dogs with circular external skeletal fixation – a retrospective study
Introduction
Small and toy breed dogs have a high inci-dence of fractures of the radius and ulna, and these fractures are often a result of minor trauma (7, 16, 19, 20, 23, 30, 31, 32, 35, 46, 47; Ljunggren G., 1969, Personal Communication). Fractures of the radius and ulna in toy and small breed dogs have a higher risk for delayed union or nonunion than similar fractures in large breed dogs (2, 5, 6, 15, 16, 19, 20, 23, 30, 32, 39, 40, 41, 44). The rea-sons for impaired healing appear to be both biomechanical and vascular (2, 5, 6, 7, 15, 23, 44). Distal radial fractures often have minimal bone surface contact after reduction because of the small size of the bones, as well as the short oblique or transverse orientation of the fracture (7, 15, 44). Anatomical alignment is further impeded by the tendency of the carpal and digital flexor muscles to create caudo-lateral displacement of the distal bone fragment (15, 19, 20, 26). Furthermore, the limited soft tissue coverage and intraosseous circulation of the radius and ulna in toy and small breed dogs may contribute to a higher frequency of nonunion (47).
Success in obtaining fracture union is dependent on the [...]
