Management of wounds with exposed bone structures using an artificial dermis and skin grafting technique

Abstract

The task of managing an open wound complicated by exposed bony structures underneath is difficult, if not challenging. We have instituted a method of managing the problems in stages using an artificial dermis and skin grafting technique in 17 wounds in 15 individuals from Sept. 2006 to Feb. 2009. While all wounds were noted to assume aberrant healing processes, the majority of involved bony structures were devoid of periosteal covering compounded by various degrees of infection. Of 15 incidents, mechanical trauma was responsible for 10, chemical burns for two and electrical burns for two patients. A chronic non-healing ulcer with exposed bone formed in an old burn scar accounted for the remaining one. The regimen of surgical management consisted of initial debridement, the coverage of the resultant wound with an artificial dermis and a partial-thickness skin grafted over this dermis-like structure grown with granulation tissues. Complete wound healing was attained in 15 out of 17 with outstanding cosmetic and minimal donor-site morbidity. Despite initial failure encountered in two, the morbidities noted were low. It is especially useful in large defects that usually require flaps for coverage.
