Abstract
In this report we describe our encounter of a case of hand trauma referred to our center presenting with incomplete left thumb amputation at metacarpal level with extensor pollicis longus (EPL) and flexor pollicis longus (FPL) tendon avulsion from the tenomuscular junction. After metacarpal bone fixation the ulnar digital artery was anastomosed and the digital nerves were coapted. Transfer of extensor indicis proprius (EIP) to EPL and side-to-side suturing of the FPL to the deep flexor tendon of the index finger were performed.
Highlights
The hand of a 24 year-old man injured during work in a factory referred to the emergency department of our hospital due to an incomplete left thumb amputation
In order to reconstruct the extensor pollicis longus (EPL) tendon, the extensor indicis proprius (EIP) tendon was harvested through a short transverse incision just proximal to the metacarpophalangeal joint; the distal stump was sutured end-to-side to the remaining extensor digitorum cummonis (EDC) tendon of the index finger to prevent extensor lag
Spontaneous rupture of EPL tendon after distal radius fracture is a common complication and transfer of EIP tendon has been successfully used for the reconstruction of the thumb extension [1,2,3]
Summary
The hand of a 24 year-old man injured during work in a factory referred to the emergency department of our hospital due to an incomplete left thumb amputation. Extrinsic tendons including flexor pollicis longus (FPL) and extensor pollicis longus (EPL) had been avulsed from tenomuscular junction (Figure 2). In order to reconstruct the EPL tendon, the extensor indicis proprius (EIP) tendon was harvested through a short transverse incision just proximal to the metacarpophalangeal joint; the distal stump was sutured end-to-side to the remaining extensor digitorum cummonis (EDC) tendon of the index finger to prevent extensor lag.
