Two-stage posterior-only procedures for correction of severe spinal deformities

Abstract

The two-stage posterior-only procedures permitting stepwise correction for the treatment of severe spinal deformities provide safe and satisfactory outcomes in this patient population.

The Use of Cranial Halo Traction Versus Temporary Internal Distraction in Staged Surgery for Severe Scoliosis: A Comparative Study

“…The average hospitalization time was 28.5 days for the first operation and 24.6 days for the second, with 6 months between them. 20 In the present study, the average hospitalization time was 52.14 days in the group that underwent internal distraction, with no significant difference in relation to the cranial traction group (53.09 days). However, it is important to emphasize that patients submitted to temporary internal distraction exhibited lower implant density when compared to the cranial traction group (0.69 x 0.84, p < 0.05).…”

The impact of posterior temporary internal distraction on stepwise corrective surgery for extremely severe and rigid scoliosis greater than 130°

“…Buchowski [19,20] reported the use of internal distraction devices that accompanied anterior and/or posterior release for deformity correction. Cheng [3] adopted the use of conventional growing rods, and another [18] group reported a case that used novel magnetically controlled growing rods for correction. However, more studies are required on the use of internal distraction to adapt and optimize the techniques for severe scoliosis (C130°) correction.…”

“…Severe scoliotic spinal deformities can cause compression of the spinal cord and thoracoabdominal structures [1][2][3], affect the thoracic cage; disturb skeletal, muscular and diaphragmatic function; and reduce respiratory system compliance [24,25]. To date, a series of long-term studies on the natural course of pulmonary impairment and severe scoliosis have shown that there is no spontaneous resolution but rather a slight decline of PFT over time [26], and this is especially the case with curves [100°, in which respiratory system compliance is decreased to levels comparable to those of adult respiratory distress syndrome, which lead to patients suffering long-term sequelae.…”
