Reducing the kyphosis effect of anterior short thoracolumbar/lumbar scoliosis correction with an autograft fulcrum effect

Abstract Background Anterior scoliosis correction is a powerful technique with the disadvantage of kyphotic effect on lumbar and thoracolumbar curves. We aimed to investigate whether cognizant interposition rib graft anteriorly at concave side scoliotic curve causes significant fulcrum enforce reduce interfusional kyphosis in anterior corrections. Methods Twenty otherwise comparable patients adolescent idiopathic (AIS) curves undergoing short ( n = 10) or without 10, matched for age, gender degree deformity) were retrospectively compared by means radiographic measurements (sagittal coronal profile, Cobb angles intersegmental deformity angles) evaluate this modified surgical technique. Results The overall amount was similar 74 60% initial 57° 53° case control group respectively mean 3 fused segments (4 screws). Statistically relevant differences found cobb apex 20° 3° 17° 9° fulcrum, p < 0.05). Creation reduced an sagittal angle 15° pre-operatively vs. post-operatively (13° 18° post-operatively), Conclusions Interfusional hyperkyphosis associated thoracolumbar/lumbar can be positioning bone autograft antero-lateral (concave) site intervertebral region create effect.
