| Popis: | Background After interbody cage implantation for posterior or transforaminal lumbar interbody fusion (PLIF or TLIF) spinal fusion surgery, pseudoarthrosis can develop. However, there are several shortcomings of the posterior approach if the interbody cage requires removal. Therefore, an anterior approach may be useful. Methods We reviewed salvage anterior lumbar interbody fusion (ALIF) for pseudoarthrosis after PLIF or TLIF performed from December 2006 to December 2016. A total of 10 patients met inclusion criteria for the study. All preoperative and postoperative clinical and radiologic parameters were recorded. Results Salvage ALIF resulted in improvements in clinical and radiologic outcomes in all cases. In 9 cases, the previously inserted cage was successfully removed. In 1 case, only 1 of the 2 previously inserted cages could be removed, as the previously inserted cage exhibited a high subsidence and remained in a diagonal position in the vertebral body. No serious complications occurred in all cases. Bone fusion was successful in all cases. Conclusions ALIF is useful for salvage surgery to treat failed PLIF or TLIF. The advantages of salvage ALIF include improvements in clinical and radiologic outcomes and a low complication rate after surgery. To successfully remove a previously inserted cage, the vascular window of the anterior index level and the degree of subsidence of the cage should be well characterized through preoperative radiologic imaging. |
