"A free thenar flap--a case report".

Area of Science:

• Hand surgery
• Microsurgery
• Reconstructive surgery

Background:

• Degloving injuries to the hand, particularly the fingers, present significant reconstructive challenges.
• Restoring both form and function is crucial for patient outcomes.
• Free thenar flaps offer a potential solution for complex soft tissue defects.

Purpose of the Study:

• To report a case of free thenar flap reconstruction for a volar degloving injury of the right middle finger.
• To highlight the advantages of using a free thenar flap in this specific clinical scenario.

Main Methods:

• A free thenar flap, a fasciocutaneous flap with neurovascular supply from the superficial radial artery and its nerve, was harvested.
• The flap was transferred to reconstruct the degloved segments of the distal and middle phalanges of the right middle finger.
• Post-operative management involved monitoring flap viability and function.

Main Results:

• The free thenar flap provided adequate soft tissue coverage for the injured finger segments.
• The flap demonstrated good viability and sensory recovery.
• The donor site exhibited low morbidity and was closed primarily.
• No post-operative immobilization was required, allowing early mobilization.

Conclusions:

• Free thenar flaps are a viable and effective option for reconstructing volar degloving injuries of the fingers.
• This technique offers advantages such as good cosmesis, texture match, low donor site morbidity, and early functional recovery.
• The absence of required immobilization simplifies post-operative care and improves patient compliance.
