Study design: Prospective case series. Purpose: To describe a new technique for anterior column reconstruction after kyphectomy in myelomeningocele patients using titanium mesh cage and to evaluate outcomes and complications. Methods: Sixteen patients with severe dorsolumbar kyphosis 2ry to myelomeningocele were enrolled with a mean age of 10.1 years. Kyphectomy procedure and long spinopelvic fixation were done, titanium mesh cage was used to reconstruct the anterior column. Operative time and intraoperative blood loss were calculated. Using the Cobb method, pre and postoperative measurements of local/regional kyphosis were done. Degree and mean percentage of correction were calculated. Anterior intervertebral height of the kyphotic area was also measured. The mean follow-up period was 27 months. Results: Operative time was 271.3 min ± 25, and estimated intraoperative blood loss was 781.3 mL ± 92.3. On average, 2.5 vertebrae were resected. All 16 patients were able to lie supine immediately postoperatively. The mean preoperative local/regional kyphosis was 107.5°, and 106.9° respectively, corrected to 22.5° and 28.8° postoperatively, with a mean degree of correction of 85° and 78.1° respectively. Mean preoperative anterior intervertebral height was 3.54 cm, improved to 4.64 cm postoperatively. Only 2 cases had a superficial wound infection managed conservatively. At the latest follow-up, no loss of correction pseudoarthrosis occurred, and all patients showed solid fusion. Conclusion: Titanium mesh cage is an efficient, easy method for anterior reconstruction following kyphectomy in myelomeningocele patients, to maintain postoperative correction.
