Summary

The anterior osteotomy offers a powerful surgical technique for correcting rigid cervical spine deformities, applicable throughout the cervical spine and in the coronal plane. This method provides an alternative to posterior approaches, addressing limitations of traditional osteotomies.

Articulations of the Vertebral Column

Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Area of Science:

Orthopedic Surgery
Neurosurgery
Spinal Deformity Correction

Background:

Rigid cervical spine deformities cause pain, disability, and reduced quality of life.
Traditional posterior approaches like opening wedge osteotomy and pedicle subtraction osteotomy (PSO) have limitations.
PSO is restricted to lower cervical/upper thoracic levels due to anatomical constraints.

Purpose of the Study:

To review the technical nuances of the anterior osteotomy for cervical spine deformity correction.
To highlight patient selection, preoperative planning, and surgical technique for anterior osteotomy.
To present the anterior osteotomy as a versatile technique for various cervical deformities.

Main Methods:

Review of literature and surgical techniques for anterior cervical osteotomy.

Keywords:

Osteotomy anterior cervical deformity rigid deformity

Discussion of anatomical considerations and potential complications.

Emphasis on preoperative planning and patient selection criteria.

Main Results:

The anterior osteotomy can be applied throughout the cervical spine, including the coronal plane.
It avoids limitations associated with posterior approaches, such as instability and anatomical restrictions.
The technique involves osteotomy through disc spaces and uncovertebral joints to the transverse foramina.

Conclusions:

The anterior osteotomy is a powerful and versatile technique for correcting rigid cervical spine deformities.
It offers advantages over traditional posterior methods, expanding treatment options.
Proper patient selection and meticulous surgical technique are crucial for successful outcomes.
