An alternative approach in the treatment of thumb web contracture skin defects: lateral tarsal artery flap.

Background: Thumb web contracture is a common complication after hand injury, and can markedly affect whole hand function. Therefore, surgery involving thumb web reconstruction is often necessary to restore normal function of the involved hand. In this study, we present the application of the lateral tarsal artery (LTA) flap in first web reconstruction.

Methods: From November 1, 2005 to October 31, 2007, seven patients with severe post trauma or burn contractures around the first web space were treated with a LTA flap. All the patients were followed up.

Results: All flaps survived, with an average size of 6.7 cm x 4.8 cm. There were no complications or recurrent contractures during follow-up. All patients were satisfied with the esthetic appearance and functional outcome of the reconstruction.

Conclusion: The LTA flap could be an excellent option for covering various defects in the thumb web space, serving as an excellent alternative for the thumb web space reconstruction.
