Trigger digits: principles, management, and complications.

Area of Science:

• Orthopedics
• Hand Surgery
• Musculoskeletal Conditions

Background:

• Stenosing tenosynovitis, commonly known as trigger finger, is a frequent condition encountered in hand surgery.
• It typically arises from a size discrepancy between the flexor tendon and the first annular (A-1) pulley.
• Conservative treatments include splinting and corticosteroid injections, while surgical options involve A-1 pulley release.

Purpose of the Study:

• To provide a comprehensive understanding of trigger finger.
• To outline the pathomechanics, risk factors, and diverse treatment strategies for this condition.
• To emphasize the importance of considering comorbid conditions in treatment planning.

Main Methods:

• Review of conservative management options such as splinting and corticosteroid injections.
• Description of surgical interventions including open and percutaneous A-1 pulley release.
• Discussion of potential complications like bowstringing and digital nerve injury.
• Exploration of modified treatments for specific patient populations, including those with rheumatoid arthritis, diabetes, and children.

Main Results:

• A-1 pulley release is a common surgical treatment for trigger finger.
• Comorbid conditions significantly influence treatment decisions; rheumatoid arthritis may necessitate tenosynovectomy, while diabetic patients may respond less favorably to conservative care.
• Pediatric trigger thumb often resolves with A-1 pulley release, though other digits might require more extensive procedures.

Conclusions:

• Effective management of trigger finger requires a thorough understanding of its underlying pathomechanics and individual patient factors.
• Treatment approaches must be tailored, considering comorbidities and patient-specific needs for optimal outcomes.
• While complications are rare, awareness and appropriate surgical techniques are crucial for successful treatment.
