What is Compression Plating for Nonunion?
Compression plating for nonunion is a surgical procedure used to treat a fracture that has failed to heal (nonunion). In this technique, the surgeon stabilizes the broken bone using a metal plate and screws while applying controlled compression across the fracture site.
The compression brings the bone ends firmly together, improving stability and stimulating bone healing. Often, the procedure also includes removal of scar tissue at the nonunion site and placement of a bone graft to enhance healing.
It is commonly used for long bones such as the humerus, femur, tibia, or forearm bones when previous treatments have not resulted in proper healing.
When is Compression Plating for Nonunion Indicated?
Compression plating for nonunion is indicated when:
- A fracture has failed to heal after an adequate period (typically 6–9 months), with little or no signs of bone healing.
- There is an atrophic (poor biological activity) or hypertrophic (excess callus but unstable) nonunion requiring improved stability.
- Previous treatments (such as casting, intramedullary nailing, or external fixation) have failed.
- There is mechanical instability at the fracture site.
- Malalignment or deformity needs correction along with stabilization.
- Hardware failure (broken nail or screws) has occurred.
- Bone grafting is needed to stimulate healing, especially in atrophic nonunion.
How Should I Prepare for Compression Plating for Nonunion?
Before compression plating for nonunion, your doctor will perform blood tests and imaging studies. Inform them about medications, allergies, or medical conditions. Stop smoking and certain medicines like blood thinners as advised. Arrange help at home for recovery. Follow fasting instructions before surgery. Maintain good nutrition to support bone healing and recovery.
What Should I Expect During Compression Plating for Nonunion?
During compression plating for nonunion, you will receive general or regional anesthesia. The surgeon makes an incision over the fracture site, removes scar tissue, and refreshes the bone ends to stimulate healing. The bone is realigned properly, and a metal plate with screws is applied to create firm compression across the fracture. A bone graft may be added if needed. The wound is then closed with sutures, and a dressing or splint is applied for protection.
What Happens After Compression Plating for Nonunion?
After the procedure, you can expect pain, swelling, and mild discomfort, which are managed with medications. The limb may be supported with a splint or brace initially. Your doctor will advise on wound care, activity restrictions, and weight-bearing limits. Physical therapy may begin gradually to restore movement and strength. Follow-up visits with X-rays are scheduled to monitor bone healing. Complete recovery may take several months, depending on the bone involved and overall health.
What are the Risks and Benefits of Compression Plating for Nonunion?
Benefits
- Promotes bone healing by providing strong stability and compression
- Corrects deformity and restores proper bone alignment
- Allows early controlled movement in many cases
- High success rate, especially when combined with bone grafting
- Reduces pain caused by instability at the nonunion site
Risks
- Infection at the surgical site
- Bleeding or blood clots
- Nerve or blood vessel injury
- Failure of the bone to heal (persistent nonunion)
- Hardware irritation or breakage
- Need for additional surgery in some cases
