Correction of rigid cervical deformities often requires osteotomies to realign the spine. Cervical pedicle subtraction osteotomy can be technically challenging due to the presence of cervical nerve roots and usually can only be performed at C7 or T1 due to the presence of vertebral arteries. In contrast, anterior cervical osteotomy can be performed throughout the cervical spine and is a safe and effective method for correction of both sagittal and coronal cervical deformities. We describe the anterior cervical osteotomy technique with a review of the pertinent literature.
A step-by-step technical guide for anterior cervical osteotomy is provided with a focus on surgical nuances and complication avoidance. Two illustrative cases of fixed sagittal and coronal deformities are included to demonstrate the substantial amount of deformity correction achievable using the anterior cervical osteotomy technique.
Both patients in the illustrative cases had successful clinical and radiographic outcome following deformity correction utilizing the anterior cervical osteotomy technique.
Anterior cervical osteotomy is a safe and effective technique for correction of rigid cervical deformities. Spine surgeons should be familiar with this technique to optimize clinical outcome in patients undergoing cervical deformity correction.
矫正僵硬的颈椎畸形通常需要进行截骨术来使脊柱重新排列。由于存在颈神经根，颈椎椎弓根截骨术在技术上具有挑战性，并且由于椎动脉的存在，通常只能在C7或T1进行。相比之下，颈椎前路截骨术可在整个颈椎进行，是矫正颈椎矢状面和冠状面畸形的一种安全有效的方法。我们描述了颈椎前路截骨术技术并回顾了相关文献。
提供了一份颈椎前路截骨术的分步技术指南，重点关注手术细节和并发症的避免。纳入了两例固定矢状面和冠状面畸形的病例，以证明使用颈椎前路截骨术技术可实现大量的畸形矫正。
在使用颈椎前路截骨术技术矫正畸形后，两例病例中的患者临床和影像学结果均成功。
颈椎前路截骨术是矫正僵硬颈椎畸形的一种安全有效的技术。脊柱外科医生应熟悉该技术，以优化颈椎畸形矫正患者的临床结果。
