Overview
Brief Summary
This retrospective study is to determine whether age is a risk factor for postoperative complications in patients undergoing transforaminal lumbar interbody fusion; specifically whether the risk (odds) of implant failure and the need for revision surgery increases with age.
Detailed Description
Spinal fusion is one of the most commonly performed surgical procedures for the treatment of degenerative spinal disease. Interbody fusion with cages reconstructs the anterior column through disc removal, allowing to maintain proper disc height despite weight bearing, while providing firm fixation of the spinal segments. Transforaminal lumbar interbody fusion (TLIF) has fewer complications and less intraoperative bleeding than posterior lumbar interbody fusion (PLIF). Elderly patients are at high risk for perioperative and postoperative complications after lumbar fusion. This retrospective study is to determine whether age is a risk factor for postoperative complications in patients undergoing transforaminal lumbar interbody fusion; specifically whether the risk (odds) of implant failure and the need for revision surgery increases with age.
