Brief Summary

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.

Conditions

Trauma

Keywords

Finger pulp reconstruction; dorsal branch; proper digital nerve; palmar arterial arch; dorsal digital island flap

Outcome Measures

Primary Outcomes (1)

• static 2-point discrimination test

  The patients were assessed at follow-up by an independent senior surgeon who did not attend the treatments. Evaluation included active range of motion (ROM) of the DIP and proximal interphalangeal (PIP ) joints, and static 2-point discrimination (2PD) and Semmes-Weinstein monofilament test of the reconstructed finger pulps. These measurements were compared with those on the contralateral site. According to the Michigan Hand Outcomes Questionnaire (MHQ), patients reported their satisfaction with the appearance of the injured hand. The questions based on a 5-point response scale.

  Patients were followed for 16-23 months (mean, 19 months)

Secondary Outcomes (1)

• Semmes-Weinstein monofilament test

  Patients were followed for 16-23 months (mean, 19 months)
