The radius and ulna

Abstract

Fractures of the radius and ulna account for 17/18% of all fractures in small animals, predominantly affecting the middle and distal third of the diaphysis. This chapter looks at anatomy; proximal fractures, diaphyseal fractures, distal radial and ulnar fractures. Operative techniques: Tension-band application to the proximal ulna; Plate application to the caudal ulna for simple fractures; Stabilization of comminuted proximal ulna fractures; Fractures of the ulna with concurrent luxation of the radial head (Monteggia fractures); Fractures of the proximal radius; Ulnar diaphyseal fractures – intramedullary pinning; Radial diaphyseal fractures – external fixation; Radial diaphyseal fractures – bone plating; Distal radial fractures – mature dog; Distal radial fractures – Salter-Harris type I; Styloid fractures.
