Fractures of proximal ulna and radius
Olecranon avulsion fractures can be managed with tension band wire fixation, placing Kirschner wires perpendicular to the fracture line, and applying tension band wires to the posterior border of the bone to resist.
Eliminate triceps pull. If the proximal bone fragment is large enough, a more rigid bone plate can also be considered for fixation.
proximal radius fracture
For proximal radius fractures, the size of the proximal fragment can determine the implant to be used. Those with more bone mass can be stabilized with non-locking or locking plates,
T-plates are generally more used. If the dog is too small, too young, or has insufficient proximal bone to use a bone plate, a crossed Kirschner wire is also generally used.
The ulna and radius diaphysis fractures of small dogs are different from those of large dogs, and their extraperiosteal vascular density is lower, so the use of too wide and too rigid bone plates should be avoided. in simple
In the case of fracture, a limited contact dynamic compression plate should be used, and the fracture end should be compressed under the condition of improving blood flow, so that it can complete primary healing.
If it is a comminuted fracture that cannot be reduced, how can a locking bone plate be used to play the role of an endoskeleton fixator, only the axial alignment of the fracture, and the
The bone fragments and blood callus in the fracture area were not intervened to complete secondary healing.
Long plates spanning the entire radius have more mechanical advantages than short plates. Since the long bone plate will improve the working leverage of the bone screw and make the bending force
It can be more evenly distributed with the bone plate, thereby reducing the pull-out force acting on the bone screw.
Fractures of distal radius and ulna
distal radius growth plate fracture
Compared with proximal radius fractures, which are more common in small dogs, the treatment is similar to that of proximal radius fractures. T-plates are more commonly used, with locking or compression.
The T-shaped plate is more suitable, and if the use of the plate is limited, cross or parallel Kirschner wire fixation can also be used.
Styloid process fractures
Fractures of the radial styloid process are usually intra-articular and cause medial instability of the wrist joint.
Correctly reset and fix.
Fractures of the ulnar styloid process are imaged for stabilization of the lateral wrist joint, which is also immobilized with Kirschner wires and tension wires.
