Summary
Extensor indicis proprius to extensor pollicis longus tendon transfers offer good long-term outcomes for patients with distal radius fractures. This procedure aids in restoring thumb and index finger function after extensor pollicis longus tendon rupture.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Reconstructive surgery
Background:
- Spontaneous rupture of the extensor pollicis longus (EPL) tendon is a known complication after distal radius fracture treatment.
- Both operative and nonoperative management of distal radius fractures can lead to EPL tendon rupture.
Purpose of the Study:
- To evaluate the long-term clinical outcomes of extensor indicis proprius (EIP) to EPL tendon transfers.
- To assess functional recovery in patients who underwent EIP to EPL tendon transfer for distal radius fracture complications.
Main Methods:
- Retrospective case series of patients undergoing EIP to EPL tendon transfer from 2005-2015.
- Collected data on active range of motion (ROM) of the index finger metacarpophalangeal (MCP) and thumb interphalangeal (IP) joints.
- Assessed digital extension against resistance, subjective patient complaints, and QuickDASH scores.
Main Results:
- Seven patients (6 female, 1 male; mean age 54 years) were included.
- 100% achieved isolated active index finger MCP extension; 86% had extension against resistance.
- Mean QuickDASH score was 16, indicating moderate functional impairment.
Conclusions:
- Extensor indicis proprius to EPL tendon transfers demonstrate favorable long-term functional and patient-reported outcomes.
- This tendon transfer is an effective reconstructive option for EPL tendon rupture following distal radius fractures.
