Composite Grafting for Pediatric Fingertip Injuries

Abstract

Background Fingertip injuries are common in the pediatric population. Composite grafting is a frequently used technique for distal amputations in children given the reported success rate. We sought to study the early clinical results of composite grafting for fingertip injuries in the pediatric population. Methods A retrospective review was performed over a 5-year period at a tertiary care pediatric hospital to identify those patients who underwent composite grafting of fingertip injuries. Patients were included if they were 18 years old or younger and sustained an injury distal to the distal interphalangeal joint (or thumb interphalangeal joint). Demographic information was recorded. Graft viability was characterized as no take, partial take, or complete take. The number of secondary procedures and number and duration of follow-up appointments were recorded. Hypothesis testing was done using ordinal logistic regression analysis. Results Thirty-nine patients underwent fingertip composite grafting. The mean age was 5.9 years (1–18 years); there were 24 males (61.5 %) and 15 females (38.5 %). Thirteen patients had no graft take (33.3 %), 23 patients had partial take (59.0 %), and three patients had complete take (7.7 %). Only four patients underwent secondary revision (10 %). The median number of follow-up appointments was 3 and the average follow-up time was 4.5 months. Age did not appear to have a statistically significant influence on graft take. Conclusions Fingertip composite grafts rarely take completely even in young children. Despite poor viability, however, most patients will have at least partial graft take and do not undergo additional reconstructive procedures.
