Reconstruction of finger pulp defect with reversed fasciocutaneous island flap from same finger.

Objective: To investigate the clinical curative effect of reconstruction of finger pulp defect by anastomosis of reversed fasciocutaneous island flap with dorsal branch of the digital nerve of the same finger.

Methods: The restoration of finger pulp defect with fasciocutaneous island flap from the same finger was conducted in 25 cases (30 fingers) from January 2002 to June 2003. Nine patients (11 fingers) whose flaps with dorsal branch of the digital nerve anastomosed with the digital inherent nerve around the surface of the wound were Group A and the others were Group B. The follow-up was carried out at 3 and 9 months after the operation to observe the shape of finger pulp and the sense restoration between two groups.

Results: All flaps of 25 cases (30 fingers) survived. Three months after operation, the patients had fully grown finger pulps and recovered the superficial sensation and tactile sense of finger pulps. The two point discrimination on average was 5.00 mm+/-0.23 mm in Group A and 6.00 mm+/-0.30 mm in Group B. The difference between two groups was highly significant. Nine months later, their senses of finger pulps between two groups were recovered basically.

Conclusions: The reversed fasciocutaneous island flap from the same finger is the first choice to reconstruct the finger pulp defect, and the anastomosis of dorsal branch of the digital nerve shall be determined according to the specific condition.
