Little finger-to-thumb microvascular transfer

Area of Science:

• Orthopedic Surgery
• Microsurgery
• Hand Reconstruction

Background:

• Thumb amputation presents significant functional challenges for manual laborers.
• Restoration of thumb function is crucial for regaining prehensile capabilities.

Observation:

• A case report details a unique thumb reconstruction for a manual laborer with an amputated dominant right thumb.
• The reconstruction utilized microvascular transfer of a previously partially amputated little finger from the same hand.

Findings:

• Postoperative assessment at 1 year revealed excellent grip and pinch strength.
• The reconstructed thumb demonstrated full opposition to all digits.
• Static two-point discrimination measured at 8 mm, indicating good sensory recovery.

Implications:

• This reconstructive technique offers a viable solution for thumb loss in manual laborers.
• The procedure successfully restored critical hand functions, enabling return to work.
• The findings contribute to the literature on innovative hand reconstruction strategies.
