Summary
Rheumatoid arthritis can cause swan-neck and buttonhole deformities, impacting daily activities. Surgical interventions, from early synovectomy to advanced reconstruction, aim to restore finger function.
Area of Science:
- Orthopedics
- Rheumatology
- Hand Surgery
Background:
- Rheumatoid arthritis frequently leads to characteristic swan-neck and buttonhole deformities in the fingers.
- These deformities progress through stages, affecting joint mobility and daily life activities.
Purpose of the Study:
- To describe the pathology and stages of swan-neck and buttonhole deformities in rheumatoid arthritis.
- To outline surgical indications for different stages of these deformities.
Main Methods:
- Pathological analysis of swan-neck and buttonhole deformities.
- Review of surgical interventions based on disease stage.
Main Results:
- Swan-neck deformity originates at the metacarpophalangeal joint.
- Buttonhole deformity originates from proximal interphalangeal joint synovitis.
- Early stages may benefit from synovectomy and soft tissue balancing.
Conclusions:
- Surgical treatment for rheumatoid arthritis finger deformities depends on the stage.
- Advanced stages may require complex reconstructions, including alloarthroplasty or arthrodesis for functional restoration.
