Summary
Splinting is crucial for treating boutonniere deformity by maintaining tendon continuity and correcting joint contractures. Surgical intervention may be necessary for persistent issues, guided by the deformity
Area of Science:
- Orthopedics
- Hand Surgery
- Anatomy
Background:
- Boutonniere deformity involves an imbalance in the dorsal tendon apparatus.
- Understanding this anatomy is key to effective treatment.
Purpose of the Study:
- To outline the pathophysiology and treatment of boutonniere deformity.
- To emphasize the role of splinting and surgical interventions.
Main Methods:
- Review of the anatomy and pathophysiology of boutonniere deformity.
- Discussion of splinting techniques for acute, chronic, and postoperative stages.
- Overview of surgical options for persistent tendon imbalance and joint contractures.
Main Results:
- Splinting is essential for maintaining central tendon continuity and correcting PIP joint flexion contractures.
- Surgery is frequently required, with procedural choice dependent on deformity stage and extensor mechanism integrity.
- Rebalancing procedures include tenotomy, lysis, or release of retinacular structures and extensor tendon insertions.
Conclusions:
- Effective treatment of boutonniere deformity relies heavily on appropriate splinting.
- Surgical interventions are vital for restoring extensor mechanism function when conservative measures fail.
