Review shows similar or lower complication rate with anterior column realignment vs other techniques
According to this literature review, anterior column realignment for adult spinal deformity correction provided comparable or lower complication rates with restoration similar to other methods.
Researchers performed a literature review using PubMed and identified all published reports on minimally invasive anterior column realignment (ACR) for adult spinal deformity correction.
Twelve papers were included in the study.
Investigators noted 10° to 27° of segmental lordosis was found with the use of hyperlordotic cages. The mean intradiscal angle had a 19° increase when posterior column osteotomy was combined with ACR, which was 13° greater than figures reported with the use of lateral lumbar interbody fusion without the use of a hyperlordotic implant.
The literature showed complication rates with ACR of between 18% and 47%. Transient hip flexion weakness and transient paresthesia or dysesthesia were the most common minor complications with rates of 9.3% and 12%, respectively.
The studies reported few major complications, with the most common being bowel perforation or vascular injury. Of 75 cases, 11 cases reported a motor deficit which was lower than the rates reported with three column osteotomy. ‒ by Monica Jaramillo
