    Abstract:
    One of the surgical goals during the treatment of adolescent idiopathic scoliosis (AIS) is to preserve segments and thus mobility while achieving a well-balanced spine on all planes. The transforaminal interbody fusion (TLIF) technique allows for a significant degree of rotational correction and thus may allow for preservation of more mobile segments. This retrospective study analyzed the use of TLIF in AIS patients who underwent surgery between 2006 and 2009 at a single center, and discusses the degree of curve correction, complications and outcomes. All curves were classified using the Lenke classification system. Standing posterior-anterior Cobb angle, sagittal and coronal balance, percent correction, and end/stable/neutral/apical vertebra were determined on preoperative, postoperative and follow-up radiographs. Nine patients were identified (eight women and one man) ranging in age from 11.6-18 years. All TLIF procedures were performed at the L2/3 level. Lenke curves included 5CN (n=5), 5BN (n=2), and 6CN (n=2). Average follow-up was 27.4 months (range, 12-57 months). Average postoperative curve correction was 79%. One patient underwent revision surgery. All patients remained stable from a clinical and radiographic standpoint on their last follow-up visit. TLIF is an important adjunct in the surgical management of select AIS patients. By allowing for greater rotational correction, it may be possible to preserve one more mobile segment without decompensation or overcorrection. To our knowledge, this is the first report on the role of TLIF in AIS. Future studies are warranted in determining those who will maximally benefit from this technique.
