Foreign body reactions to absorbable implant fixation of osteotomies

The authors present two case studies which describe a destructive, nonspecific foreign-body reaction encountered while using the Biofix absorbable rod system. At Dallas Family Hospital, the Biofix system has been used in 32 first metatarsal procedures, 10 lesser metatarsal procedures, and 15 digital procedures. Twenty-seven patients are included, with two developing a reaction that required surgical drainage and debridement. The first reaction was noted to be extremely violent with destruction of bone and soft tissue. Prompt diagnosis and aggressive therapy is necessary to minimize the soft tissue and bony destruction that may occur. Surgical drainage and debridement are often necessary to control the reaction.
