Posterior Transvertebral Osteotomy for Adult Thoracolumbar Kyphosis

Pedicle subtraction osteotomy through pseudarthrosis to correct thoracolumbar kyphotic deformity in advanced ankylosing spondylitis

“…In the authors' opinion, the procedure is more similar to the spinal shortening. However, in the spinal shortening procedure, the correction at one level will not exceed 40° [13,17]. In this series, the average kyphotic deformity is 75°.…”

Three-stage surgery in the management of severe rigid angular kyphosis

“…The average length of hospitalization was 14 days (8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22).…”

“…Posterior osteotomies have been widely used for this purpose. Various techniques consisting of partial and total posterior wedge osteotomies have previously been described [3,8,9,11,14,15,16,18]. The apex of the correction axis lies in the anterior surface of the corpus in posteriorly placed osteotomies.…”

“…All patients were evaluated preoperatively for pain, functional status and appearance of the deformity by the Likert scoring system [9]. Statistical comparisons between preoperative and postoperative scores were performed using the Wilcoxon signed-rank analysis.…”

“…Some of them attempt to solve the problem by posterior wedge osteotomies [3,8,9,11,14,15,16,18], while others have preferred combined procedures [2,5,6,7,10,13]. Favourable results have been attained by all these techniques for the correction of deformities not exceeding 50°-60°.…”
