Brief Summary

To treat congenital cervical scoliosis, previous literature introduced surgical technique, like hemivertebra resection by anterior and posterior approach. Although this technique is effective, it has a lot of disadvantages. So investigators introduce another surgical technique.

Detailed Description

Although hemivertebra resection technique can obtain satisfactory clinical outcome, it has its disadvantages. Because of the presence of vertebral arteries, the procedure of cervical hemivertebra resection is not only difficult and risky, but also time and labor consuming. The operation is a great challenge to the skill, physical strength and energy of the surgical team. Meanwhile, hemivertebra resection and compression on convex side may lead to iatrogenic foraminal stenosis and increase the incidence of nerve root palsy at the corresponding segment after surgery. The shortening of the convex side may further aggravate the patient's existing short neck deformity, which is not conducive to the recovery of patient's appearance. Therefore, our department pioneer a new surgical technique to avoid hemivertebra resection in 2015, which is distraction and lateral opening on concave side. This technique extends the concave side through intervertebral space where the concave apex locates or adjacent intervertebral space to achieve the purpose of scoliosis correction. The avoidance of hemivertebra resection significantly reduces the difficulty and risk of the surgery. This procedure tries to make up for the patient's congenital anatomical deficiency and lengthen the concave side. Although there is no need to expose vertebral artery, preoperative CTA(computed tomography angiography) should be performed routinely to determine whether there is abnormality in vertebral artery and whether it will interfere with the distraction on concave side and the placement of prosthesis.
