Colonic perforation complicating posteroanterior fusion using fibular strut autograft for a high-grade spondylolisthesis.

Posteroanterior fusion using a fibular strut autograft has been advocated for the surgical treatment of high-grade lumbosacral spondylolisthesis. We report here the treatment of a 14-year-old girl using an S2-L5 fibular autograft, which resulted in the postoperative complication of a sigmoid colon perforation. Techniques for recognizing, treating, and avoiding this complication are presented.
