Dowel pinning

Dowel Pinning: A Trusted Surgical Technique to Stabilize Broken Bones and Joints in Pets

Dowel pinning is a surgical technique used to stabilize certain types of fractures and joint injuries by inserting a strong metal pin through the affected bone. This pin acts like an internal support rod, helping the bone stay aligned while it heals.

Although newer implants exist, dowel pinning is still widely used in veterinary orthopedics because it is reliable, versatile, and effective—especially in pelvic fractures, growth plate injuries, and specific avulsion fractures.

When Do Pets Need Dowel Pinning?

Your veterinarian may recommend dowel pinning if your pet has:

• A pelvic or sacroiliac (SI) injury, commonly seen in road accidents

• A fracture near the growth plate (common in young cats and small dogs)

• A small bone fragment pulled out of position (avulsion injury)

• A fracture where additional reinforcement is helpful

The goal is always the same: to restore stability, reduce pain, and help your pet return to normal mobility.

How the Procedure Works

A smooth metal pin (called a Steinmann pin) is placed through the injured bone in a way that restores alignment and holds the pieces securely.
Depending on the injury, the pin may:

• Cross a joint (such as the SI joint)

• Pass along the bone canal

• Hold a small avulsion fragment in place

• Be combined with other implants like plates or wires

This creates a stable environment to allow safe, natural healing.

Recovery After Dowel Pinning

After surgery, your pet will need:

• Strict rest for 4–8 weeks

• Short, controlled leash walks only

• An Elizabethan collar (cone) to prevent licking

• Daily checks of the incision for redness, swelling, or discharge

Your veterinarian will schedule follow-up X-rays to ensure the bone is healing properly.

Most pets begin using the limb within days, and their comfort continues to improve over the following weeks.

Long-Term Outlook

Dowel pinning has an excellent success rate. Pets typically return to comfortable daily activity once healing is complete.
Some pins may need to be removed later if they cause irritation, but this is not always necessary.

FAQs

1. Will my pet be able to walk after surgery?

Yes. Most pets begin using the limb again within a few days, depending on the injury.

2. Will the metal pin stay in forever?

Sometimes. In many cases, the pin can stay in permanently. If it causes irritation, it can be removed easily.

3. How long is the healing period?

Most injuries heal within 6–8 weeks, though some severe fractures may take longer.

4. Is this surgery painful?

Your pet receives pain medication before, during, and after surgery. Most pets feel significantly better once the fracture is stabilized.

5. Are complications common?

Complications are rare. The most common issue is pin migration, which is monitored on follow-up X-rays.
