“…Recently, Leatherman and Dickson [22] popularized it again. In many subsequent studies, it has been reported that complete excision of hemivertebra at the same session at one or two steps leads to pronounced improvement as well as spontaneous correction [4,7,10,19]. Bradford and Boachie-Adjei reported a 70% correction in Cobb angle.…”

“…This can be done by correctional cast braces. Filling and closing of the space by compression is easier with instrumentation applications [1,5,10]. On the other hand, instrumentation in children brings about the problems of finding suitable pediatric instruments, subcutaneous protuberance of the instruments, difficulty in wound closure, wound healing problems, and infection.…”

“…Several recent reports recommend the simultaneous performance of two procedures during the same session as this is more reliable and efficient [4,8,9]. Complete excision of hemivertebra from posterior is quite easy and reliable [10,11].…”

“…Correction rate of scoliosis is reported from 35.2% to 70% 4-6,9-12,23 , whereas correction rate of kyphosis is from 54.2% to 67.4% [9][10][11][12] . Our cases were in no way inferior to these reports which showed 36.8% and 55.5%, respectively.…”

“…[9][10][11][12][13] Hemivertebral resections using a single posterior approach has the advantage of less surgical impact; however, the procedure carries risk, including neurovascular injury and insufficient osteotomy. To solve these problems, since 2003 we have attempted hemivertebra resections using single-stage surgery via a posterior approach alone, utilizing CT-based navigation system.…”

Congenital hemivertebra is commonly treated with posterior hemivertebra resection with bilateral transpedicular fixation. However, implant-related complications are common in children younger than 5 years old who undergo this surgical procedure. objective: To present the preliminary clinical and radiological outcomes of children younger than 5 years old treated by posterior hemivertebra resection and 3-rod fixation technique. methods: From January 2016 to December 2017, 14 consecutive patients of congenital scoliosis with 16 hemivertebrae were retrospectively reviewed, including 5 girls and 9 boys, aged between 25 and 55 months old (average, 37.6 months). All patients underwent posterior hemivertebra resection with short fixation with bilateral pedicle screws and a convex lamina hook. Surgical complications and corrective outcomes were assessed based on the clinical charts and spinal radiographs with a minimum 24-month follow-up. Results: The mean Cobb angle of the main curve was 38.4° before surgery, 8.5° after surgery, and 8.7° at final follow-up. In the compensatory cranial curve, the preoperative Cobb angle of 16.8° was corrected to 8.1° postoperatively and was 10.3° at final follow-up. In the compensatory caudal curve, the preoperative Cobb angle of 15.9° improved to 5.3° postoperatively and was 7.8° at final follow-up. The segmental kyphosis was corrected from 13.5° to 0.5° and was 1.1° at final follow-up. There were no crankshaft phenomena, no proximal kyphosis, and no complications related to the instrumentation. interpretation: Posterior hemivertebra resection with instrumentation with bilateral pedicle screws and a convex lamina hook can achieve rigid fixation and deformity correction.

Single-Stage Excision of Hemivertebrae Via the Posterior Approach Alone for Congenital Spine Deformity

Abstract: The described procedure was less invasive because it avoided an anterior approach, yet it yielded satisfactory long-term results for thoracolumbar hemivertebrae.
