Release notes - Cat distal radius and ulna

The module on this anatomical area has been authored by Aldo Vezzoni (Italy) and Luca Vezzoni (Italy). Matthew J Allen (UK) and Amy Kapatkin (USA) acted as editors.

The cat distal radius and ulna module includes pages on:

• Fracture diagnosis
• Approaches to the distal radius and ulna
• Positioning
• Complications
• Wide selection of fracture fixation techniques tailored to the specific fracture types

Around 300 original illustrations accompany the step-by-step descriptions of the various fixation techniques and approaches.

This module is exclusively for AO VET members only.

The cat distal radial und ulnar material includes a detailed description of the following fracture types and fixation methods.

23-A1 Simple extraarticular fracture of the distal ulna:

• Nonoperative management
• Compression plate fixation
• Bridging plate fixation
• K-wires with or without tension band fixation

23-A2 Simple extraarticular fracture of the distal radius:

• Compression plate fixation
• T-plate fixation
• Bridging plate fixation
• Lag screw and neutralization plate fixation
• K-wire fixation
• External skeletal fixation

23-A3 Extraarticular multifragmentary fracture of the distal radius:

• Bridging plate fixation
• External skeletal fixation

23-B1 Partial articular sagittal fracture of the distal radius:

• Lag screw with or without antirotational K-wire fixation
• K-wires and tension band fixation

23-B2 Partial articular frontal fracture of the distal radius:

• Lag screw fixation

23-C1 Simple complete articular fracture of the distal radius with associated distal ulnar fracture:

• Lag screw and cranial plate fixation
• Lag screw and K-wire fixation

23-C2 Simple complete articular, multifragmentary metaphyseal fracture of the distal radius with associated distal ulnar fracture:

• Lag screw and bridging plate fixation
• Lag screw and medial bridging plate fixation

23-C3 Multifragmentary complete articular fracture of the distal radius and ulna:

• Pancarpal arthrodesis with a circular or hybrid external skeletal fixator
• Pancarpal arthrodesis with a plate

In addition, the material contains information about the following:

• Diagnosing each fracture type
• Indications for all treatments
• Dorsal recumbency positioning
• Cranial and craniomedial approaches to the distal radius and ulna
• Basic techniques for lag screw fixation, plate preparation, implant removal, and general considerations on external skeletal fixators
