Abstract

Purpose: First introduced by Buncke and Rose in 1979, the neurovascular partial 2nd toe pulp free tissue transfer has been attempted to reconstruct posttraumatic finger tip injuries. Although some surgeons prefer other reconstructive methods such as skin graft and local flap, we chose the partial 2nd toe pulp flap owing to its many advantages. We report three successful surgical cases in which the patients had undergone this particular method of reconstruction.
Methods: We retrospectively examined three cases of fingertip injury patients due to mechanical injury. Bone exposure was seen in all three cases, All had undergone partial toe pulp free flap for soft tissue defect coverage.
Results: All flaps survived without any complications such as partial necrosis, hematoma or dehiscence. Although tingling sensation has returned in both cases, two-point discrimination has not returned yet. Currently no patient is complaining of any pain which gradually improved during their course of recuperation. All stitches were removed on postoperative 2 weeks. Patients are satisfied with the final surgical result and there are no signs of any edema or hematoma.
Conclusion: The homodigital reconstruction of finger tip injury using the partial 2nd toe pulp flap has numerous advantages compared to other reconstructive modalities such as its resistance to wear and tear and in that it provides a non-slip palmar digital surface. However it requires microsurgery which may not be preferred by surgeons. Advanced age of the patient can be a relative contraindication to this approach since atheromatous plaque from the donor toe can compromise flap circulation after surgery. We report three successful cases which patient age was considered appropriate. Further investigation with a larger number of cases and long term follow-up is deemed necessary.
