“…It is an effective and practical tool for spine surgeons. In 2014, Yunus Atici et al [ 23 ] used Surgimap Spine to evaluate the efficacy of two-level PSO osteotomy, and concluded that computer software (Surgimap) seems to fail as an assisting method in the preoperative surgical planning of sagittal plane deformities, since its incapability of estimation the amount of bleeding and the possible buckling of the spinal cord. In my opinion, however, The main purpose of surgical planning for a spine deformity is to analyze the coronal and sagittal alignment and evaluate the effects of predicted surgical technique in order to choose the best procedure for a given patient.…”

“…Surgimap Spine, a free computer program (Nemaris Inc., New York, NY, USA) that integrates spine-related measurement and tools for surgical planning in combination with knowledge gained from the published literature, offers a pragmatic graphical method for the surgical planning of osteotomies [ 21 ]. Surgimap Spine has been used in the surgical treatment of kyphosis deformity secondary to ankylosing spondylitis, [ 22 ] osteomalacia, or inappropriate past fusion procedures [ 23 ]. The software not only provides a practical and convenient method to analyze preoperative sagittal parameters and predict proper postoperative alignment, but also simulates the procedure of osteotomy to help surgeons select appropriate surgical methods.…”

BackgroundIn the late stage of Spinal tuberculosis, the bony destruction and vertebral collapse often leads to significant kyphosis, presenting clinically as a painful gibbus deformity, with increased instability, vertebral body translations and increased risk of neurologic involvement. Vertebral column decancellation is thought to be suitable for most patients with severe rigid kyphosis. Surgimap Spine, could offer a pragmatic graphical method for the surgical planning of osteotomies. The aim of this study was to evaluate the efficacy of Vertebral column decancellation planned preoperatively with the computer software-assistance in the patients with Pott’s kyphosis.MethodsBetween May 2012 and May 2015, 18 patients with Pott’s kyphosis underwent the Vertebral column decancellation using Surgimap Spine for preoperative surgical planning. Preoperative and postoperative Konstam’s angle, sagittal vertical angle, lumbar lordosis, thoracic kyphosis, pelvic tilt and pelvic incidence were measured. Visual analog scale and American Spinal Injury Association were documented.ResultsThe Konstam’s angles decreased from 88.1° (range, 70–105°) preoperatively to 18.5° (range, 7–31°) (P < 0.01). All patients reached the physiological limits at the final follow-up. The mean VAS score was reduced from preoperative 7.1 (range, 6–8) to 1.8 (range, 1–3, P < 0.01) and the ODI improved from 65.8% (range, 58–74%) to 20.2% (range, 12–38%, P < 0.01). At final follow-up, there was radiographic evidence of solid fusion at the osteotomy site and fixed segments in all patients. Neurological function improved from ASIA scale D to E in 5 patients. The patients were followed up for 30.4 months on average.ConclusionVertebral column decancellation is an effective treatment option for severe Pott’s kyphosis. The surgical planning software Surgimap Spine can be a reliable and helpful tool that provides a simplified method to evaluate and analyze the spino-pelvic parameters and simulate the osteotomy procedure. According to individual character, the appropriate surgery strategy should be selected.

ZusammenfassungDie Korrektur von Wirbelsäulendeformitäten beim M. Bechterew erfordert eine große operative Erfahrung. Ist die OP-Indikation bei Absenkung der Blickachse und damit verbundener Einschränkung der Lebensqualität recht klar zu stellen, so erfordert die OP-Planung eine sorgfältige Beurteilung der individuellen Anatomie und des sagittalen Profils. Durch die präoperative Analyse wird, neben dem notwendigen Korrekturausmaß, insbesondere die Lokalisation und die Art der Osteotomie festgelegt. Über die eigentliche Osteotomie hinaus ist die Technik der implantatgeführten Korrektur von entscheidender Bedeutung, um Komplikationen wie eine Translation zu vermeiden. Die vorliegende Übersichtsarbeit fasst das aktuelle Vorgehen von Planung und operativer Korrektur zusammen.

“…PSO was the most popular technique for treatment of rigid kyphosis like AS, post-traumatic kyphosis (PTK) and spinal tuberculosis. For severe and rigid kyphosis, two-level PSO showed satisfactory correction, but the surgical time and blood loss were increased signi cantly [10]. The contact of upper and lower surface of closing wedge vertebra facilitates the bony fusion for PSO, but over shortening of the posterior column could compress the dura sac and increase the risk of neurologic complications [2].…”

BackgroundTo investigate the effectiveness and feasibility of a novel vertebral osteotomy technique, transpedicular opening-wedge osteotomy (TOWO) for correcting rigid thoracolumbar kyphotic deformity in patients with ankylosing spondylitis (AS).Methods18 AS patients underwent TOWO for correcting rigid thoracolumbar kyphosis. Radiographic parameters were compared before surgery, 1 week after surgery and at last follow-up. SRS-22 questionnaire was assessed before surgery and at last follow-up to evaluate clinical improvement. The operating time, estimated blood loss and complications were analyzed. ResultsThe mean operating time and estimated blood loss were 236 minutes and 595 ml, respectively. Sagittal parameters improved significantly after surgery. The height of anterior column of osteotomized vertebrae was increased significantly at 1 week after surgery and last follow-up when compared to preoperative, but the height of middle column did not changed significantly. SRS-22 scores were improved significantly at last follow-up than preoperative. Solid fusion was achieved in all patients after 12 months follow-up, no screw loosening, screw pull out or rod breakage was noticed at last follow-up. ConclusionsTOWO could achieve a satisfactory kyphosis correction by opening anterior column instead of vertebral body decancellation and posterior column closing, which simplified the osteotomy procedure and improved the surgical efficacy.
