Miss B’s Fractured Forearm

Note: The following images may be unpleasant for some readers.

A dog’s forearm is made up of 2 bones – the radius and the ulna – spanning the distance from the elbow to the carpal or wrist joint.


5-year-old Miss B the mongrel was hit by a car. The impact fractured her ulna.

Fractures are usually caused by trauma, such as being hit by a car or falling from a height. Splints, casts, pins, steel plates and screws can be used to realign the bone. Treatment will depend on the type of fracture and the age of the dog. 


For a small young dog, a fracture can be treated with a cast. For a bigger dog like Miss B, plates & screws are needed to secure the fractured bone.


Surgical correction of a radius or ulna fracture is a specialised surgery performed by Dr Dennis Choi of Mount Pleasant Veterinary Centre (Gelenggang).

The broken bones are exposed to allow for visual reduction (alignment) & placement of the plate.


After the plate is aligned, a hole is drilled in the bone where a screw will be placed.


The process of drilling, measuring & placing the screws is repeated until the bone is securely held in place.


Internal implants like these plate & screws will remain in the leg; they do not need to be removed.

After surgery, it is important to limit activity (no running or jumping) so that the bones stay aligned and heal properly. X-rays will be recommended at various time intervals to monitor Miss B’s progress and make sure it is safe to increase her activity level.

We wish Miss B speedy recovery. Her guardian say she can’t wait to resume her favourite pastimes – going to the beach, swimming and chasing squirrels!
