Posterior three-column osteotomies for the treatment of rigid thoracic kyphosis - a case series.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo evaluate the results and complications of a series of patients who underwent three-column osteotomy using the posterior approach for correction of complex cases of rigid dorsal kyphotic deformity.
methodsReview of clinical records and images of 15 consecutive cases of pedicle subtraction osteotomies, bone-disk-bone osteotomies, or vertebral column resection, recording the etiology, type and level of osteotomy, extension of fixation, complications, and pre- and post-surgical measurements of the sagittal curves and pelvic parameters.
resultsSix pedicle subtraction osteotomies were performed, one of which in two adjacent vertebrae, as well as two bone-disk-bone osteotomies and seven vertebral column resection, two of which were performed in two adjacent vertebrae. The mean correction was 39.3° for the angular kyphosis and 33.9° for dorsal kyphosis. The corrections were similar regardless of the kind of osteotomy, the operated spinal segment, or the approach in one or two levels, but this may be a sample effect. Eight complications were observed in six patients (40% of cases): two medical complications, five early and one late surgical complication (over 90 days after surgery). There were three reoperations within less than one year from the initial surgery and one case of persistent paraparesis. Clinical complications were resolved without sequelae. There was no significant loss of correction during the segment, except in two cases of major mechanical failure due to a junctional segment fracture.
conclusionDespite being complex and aggressive procedures, prone to various complications, osteotomies with resection of the three columns are highly effective in the correction of rigid kyphotic deformities and safe enough to justify its use in selected cases.
