Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Sensory reconstruction of the finger pulp is a challenging problem. This article reports repair of the finger pulp defect using the dorsal digital island flap. Both dorsal branches of the proper digital nerves (PDNs) were used for maximal sensory restoration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

From February 2008 to May 2009, the flap harvested from the dorsum of the middle phalanx of the same finger was used in 12 fingers in 12 patients. The flaps ranged in size from 2.0 × 2.0 cm to 2.8 × 2.2 cm. The mean pedicle length was 1.2 cm. Neurorrhaphy between the dorsal branches of the PDN and PDN was performed in both sides in all cases. Sensibility of the reconstructed finger pulp was evaluated by static 2-point discrimination (2PD) and Semmes-Weinstein monofilament test. The range of motion of the donor fingers was measured. The data were compared to those of the opposite sides.
