Reconstruction of Thumb Pulp Defects Using Free Lateral Great Toe Flaps

Area of Science:

• Microsurgery
• Reconstructive Surgery
• Hand Surgery

Background:

• Thumb pulp defects pose significant functional and aesthetic challenges.
• Free lateral great toe flaps are a reconstructive option for thumb defects.

Purpose of the Study:

• To evaluate risk factors and clinical outcomes of free lateral great toe flaps for thumb pulp defect reconstruction.
• To assess the efficacy and safety of this surgical technique.

Main Methods:

• Retrospective review of 31 patients treated with free lateral great toe flaps between 2009 and 2017.
• Analysis of risk factors, flap survival, postoperative functional outcomes, and complications.

Main Results:

• 20 out of 24 flaps survived completely, with an average follow-up of 20 months.
• Smoking was identified as a risk factor for flap necrosis.
• All patients reported satisfaction with functional and aesthetic recovery; complications included venous congestion and infection.

Conclusions:

• Free lateral great toe flap transfer is a successful technique for thumb pulp reconstruction.
• Patient smoking status should be considered due to its association with flap necrosis.
