OBJECTIVE: To current a minimally-invasive surgical approach utilizing cortical bone trajectory-pedicle screw (cortical screw, CS) for adjoining section pathology (ASP) after lumbar fusion surgical procedure, and to totally examine postoperative outcomes of the 2 surgical methods with both CS or typical pedicle screw (PS) for ASP in a single 12 months follow-up time.
METHODS: Amongst 59 sufferers who underwent surgical remedy for proximal ASP after lumbar fusion surgical procedure, 53 sufferers who met the examine standards (group A, 31 sufferers with typical approach utilizing PS; group B, 22 sufferers with minimally-invasive approach utilizing CS) had been enrolled within the examine. The first end result measure was the fusion fee at one 12 months after surgical procedure, and secondary end result measures included (1) affected person satisfaction, (2) medical outcomes, (three) radiologic outcomes, and (four) surgical outcomes and issues.
RESULTS: The fusion at postoperative one 12 months was achieved at 90% in group A with PS and 91% in group B with CS (P > zero.99). Affected person satisfaction at one month after surgical procedure (P = zero.03) and ache depth inside one month after surgical procedure (P = zero.04) confirmed considerably higher in group B than in group A. In surgical outcomes, blood loss, operation time, hospital keep, and incision size had been considerably decrease in group B than in group A. Different medical parameters and outcomes had been related between the 2 teams.
CONCLUSIONS: We propose that the minimally-invasive surgical approach utilizing CS for ASP could be a notable different to standard surgical approach utilizing PS.
