Brief summary
This study is intended to compare sensory restoration between the iRASP (sensate flap) and the free thenar flap (nonsensate flap). Because, it was reported that the free thenar flap has satisfactory result of sensory restoration even though the flap do not incorporate a nerve for innervation. It is worthy whether the sensate iRASP flap sacrificing a nerve is necessary. Our data will be useful for a surgeon deciding between a sensate or non-sensate flap for coverage of a volar soft tissue defect on a thumb or finger.
Interventions
The iRASP flap is a new modification of the free thenar flap for constant innervation with the PCMN(Palmar Cutaneous branch of the Median Nerve). If there is a soft tissue defect on volar aspect in thumb or fingers, especially a pinching site, the iRASP flap would be applied. The procedure of the iRASP flap takes about 3 hours. The sensory outcomes will be checked by SWM(Semmes-Weinstein Monofilaments), S2PD(Static Two-Point Discrimination) and M2PD(Moving Two-Point Discrimination) tests. The results of sensory outcomes in the iRASp group will be compared with the results in the free thenar flap group. The cases of the free thenar flap which were able to be followed up was selected among the cases that had been performed before the authors designed the iRASP flap. The cases of the free thenar flap would be reviewed by medical record and evaluated by the above methods of sensory evaluation.

Eligibility
Inclusion criteria
In both groups of the iRASP and the free thenar flap, the patients have a volar soft tissue defect on a thumb or finger. A defect is located on pinching area and relatively large not covered easily by small sized flaps like cross finger flap or free partial toe pulp flap.
Exclusion criteria
A patient having a general disease related with nerve recovery or compressive neuropathy should be excluded.
