Minimally invasive transforaminal interbody fusion for high-grade spondylolisthesis: a retrospective study analysis of a tailor-made solution.

Study Design: Retrospective study.

Purpose: We investigated cantilever reduction and fusion technique in high-grade spondylolisthesis (HGS) with minimally invasive surgery-transforaminal interbody fusion (MIS-TLIF).

Overview Of Literature: Most publications that describe minimally invasive surgeries for HGS, especially grade 4 or 5 listhesis, utilized a combined anterior and posterior approach.

Optimising deformity correction: a retrospective comparative analysis of two techniques in high magnitude curves in adolescent idiopathic scoliosis.

Study Design: A retrospective comparative study.

Purpose: To validate the hypothesis that a combination of multilevel Ponte osteotomy (PO) with intraoperative traction (IOT) results in a better correction than IOT alone in high-magnitude curves in adolescent idiopathic scoliosis (AIS) and does not possess an attributable risk of neurological injury.

Overview Of Literature: On a comprehensive review of the literature, the choice of technique adopted for curves between 65° and 100° remains controversial with no major consensus favoring one technique over the other.
