Standard Treatment Approaches

The treatment for Boutonnière deformity typically involves both conservative and surgical options, depending on the severity of the condition and the duration since the injury. Here’s a detailed overview of the standard treatment approaches:

1. Conservative Management

For mild cases or early presentations, conservative treatment is often effective:

• Splinting: The primary conservative treatment involves the use of a splint to keep the PIP joint in extension while allowing the DIP joint to move. This is usually done for about 6-8 weeks. A common splint used is the stack splint, which helps maintain the correct alignment of the finger.

• Physical Therapy: Once the splint is removed, physical therapy is crucial to restore range of motion and strength. Exercises may include gentle stretching and strengthening activities to improve function and prevent stiffness.

• Pain Management: Non-steroidal anti-inflammatory drugs (NSAIDs) may be prescribed to manage pain and inflammation during the recovery process.

2. Surgical Intervention

If conservative treatment fails or if the deformity is severe, surgical options may be considered:

• Tendon Repair: In cases where the extensor tendon is ruptured, surgical repair may be necessary. This involves suturing the tendon back together to restore function.

• Capsulotomy: If there is significant joint stiffness or if the PIP joint is severely contracted, a capsulotomy may be performed. This procedure involves cutting the joint capsule to allow for better movement.

• Tendon Grafting: In chronic cases where the tendon has retracted or is not repairable, tendon grafting may be required to restore function.

• Joint Fusion: In severe cases where the joint is irreparably damaged, fusion of the PIP joint may be considered to alleviate pain and stabilize the finger.

Post-Treatment Care

Regardless of the treatment approach, post-treatment care is essential for optimal recovery:

• Follow-Up Appointments: Regular follow-ups with a healthcare provider are necessary to monitor healing and adjust treatment as needed.

• Rehabilitation: Continued physical therapy may be required to regain full function of the finger. This can include more advanced exercises and modalities to enhance recovery.
