ABSTRACT
BACKGROUND:
Several different strategies were described on how to graduate a patient when skeletal maturity is reached after growing rod treatment. A final instrumentation and fusion is commonly performed, but the stiffness of the spine after numerous lenghthenings can be a major problem. When correction is needed in a severe and rigid curve, 3-column osteotomies (3CO) can be used as a method of bringing the spine back to a well-balanced position. This study aims to evaluate the clinical outcomes of 3CO osteotomies at growing rod graduation.METHODS:
A retrospective search of the database was performed between 1996 and 2018. Inclusion criteria were diagnosis of early-onset scoliosis, underwent 3CO at the final fusion procedure, and ≥1 year of follow-up. Indications for this osteotomy were significant sagittal and/or coronal off-balance or severe crankshaft deformity or significant distal and/or proximal adding-on. Clinical, radiographic, and operative data were analyzed. Complications were classified according to the modified Clavien-Dindo-Sink system.RESULTS:
Eight patients were included in the study with a mean age of 13.5 at graduation (male/female 2/6). The mean scoliosis angle significantly reduced from 65.6 to 39 degrees (P=0.012). Mean T1-T12 height increased from 19 to 20.5 (P=0.084) and T1-S1 from 29.6 to 31.6 (P=0.144). Five patients had a staged surgery. Average operative time was 338 minutes and blood loss was 1321 mL. Four grade 1, 1 grade 2, and 1 grade 3 complications occurred.CONCLUSIONS:
This is the first case-series in the literature reporting on the use of 3CO at growing rod graduation. These procedures can be safely and effectively used to overcome significant multiplanar deformity and/or off-balance in the graduation of patients with early-onset scoliosis and significant correction can be achieved on these severe and rigid curves. LEVEL OF EVIDENCE Level IV-case series.
