The use of Dermacell® in Fingertip Injury

1Land Seed Hospital, Taiwan

Abstract

Matrices or tissue scaffolds provide a collagen structure for tissue remodelling while the removal of viable cells aims to minimize or prevent inflammatory or immunogenic response.

Allograft collagen scaffold can support the patient’s own cellular ingrowth, ingeneered to minimize an immune response and to yeld a bio-compatible matrix and support incoming cellular growth. The decellyularized dermis retains its growth factors, native collagen scaffold, and elastin, thanks to a LifeNet Health proprietaryprocessin technology.

Introduction

Fingertip injuries are defined as those distal to the insertion of the flexor and extensor tendons Primary goal of treatment is a painless fingertip with durable and sensate skin. 1 Methods of treatment include healing by secondary intention, skin grafting, shortening of the bone and primary closure, and coverage with local or regional flaps.

History and mechanism of the injury

Treatment

For the treatment of fingertip injuries, the decision making process should proceed from the simpler techniques to the more complicated. When no bone is exposed, the open method is ideal for small or moderate sized wounds, and skin grafting should be considered for larger wounds . Distal transverse and dorsal oblique amputations with bone exposure can be treated with local advancement flaps. 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14

Conclusion

Derma cell was able to provide protection for the wound while encouraging rapid healing without the disadvantages of donor site morbidity and increased patient pain from an autograft. The rapid wound closure was encouraging and supports further use of Derma Cell for treating soft tissue trauma wounds.

Result

The wounds progressed steadily, with full wound closure being achieved (average 1 to 4 months) after initial implantation. There were no signs of infection observed and the patient did not experience any reaction to the graft. Although the wound began healing slowly initially, the authors felt that was due to the complexity of the traumatic wound.
