摘要:

Summary:Because of the multitude of hardware types and methods of use, the spine surgeon should be aware of the potential of complications and how best to avoid them. This article reviews several instrumentation techniques and their associated anatomic, mechanical, and clinical complications.

摘要:

Summary:The surgical anatomy of the cervical spine is described and illustrated. Because of their many structural and functional dissimilarities, we discuss separately the upper cervical spine and the subaxial cervical spine. Technical and surgical details are discussed as they relate to anatomical features, variants, and pathoanatomical aberrations.

摘要:

Summary:Stabilization of the unstable cervical spine can be achieved by various methods. Methods for fixation of the C1-C2 segment and C2 through C7 segments are discussed from both laboratory and clinical standpoints.

摘要:

Summary:Occipitocervical fusion is indicated in cases of instability due to congenital, traumatic, or inflammatory conditions. Standard techniques require passage of intracranial wire and sublaminar C1 and C2 wires that are secured around bone grafts. The Bohlman technique achieves occipital fixation without intracranial wire insertion. Plate and screw fixation uses AO reconstruction plates affixed with bicortical occipital screws and C2 pedicle screws. This fixation provides increased rigidity and decreases bracing requirements postoperatively.

摘要:

Summary:Surgical stabilization of the upper cervical spine for maintaining reduction and facilitating fusion following trauma or other disorders causing instability may be reliably accomplished by wiring the dorsal ring of C1 to the dorsal element of C2 and applying autogenous bone graft. Several commonly used techniques of wiring and bone grafting are described and illustrated.

摘要:

Summary:Atlantoaxial fusion may be indicated in cases of painful osteoarthritis of the atlantoaxial joints or in cases of acute and chronic atlantoaxial instability due to developmental abnormalities, trauma, infection, tumor, or aseptic inflammatory processes. The most widely used techniques are the Gallie or Brooks techniques. They rely on the integrity of the posterior arch of the atlas and often require postoperative immobilization in a Minerva cast or halo jacket. With these techniques, intraoperative reduction is sometimes lost during the healing period. This article presents a stable technique for posterior atlantoaxial fixation and fusion using transarticular screw fixation; it is based on our experience in 76 cases. In contrast to other posterior techniques of C1-C2 fusion (e.g., Gallie or Brooks), transarticular screw fixation allows stable fixation of Cl and C2 in the reduced position even in cases of absence of the posterior arch of the atlas. Minimal postoperative immobilization is required, even in the presence of gross instability or pronounced osteoporosis, as in cases of rheumatoid arthritis. In cases of cranial assimilation of the atlas, this technique may be combined with occipitocervical fusion together with posterior decompression of the occiput and C1, if necessary. The patients are mobilized the first or second day after surgery with a Philadelphia- type collar for 6-12 weeks. The technique is contraindicated in cases of collapse of C2 due to massive rheumatoid destruction of the lateral masses.

摘要:

Summary:Screw fixation of odontoid fractures is a technically demanding procedure. However, in the hands of a fellowship trained spine surgeon, it is an important augmentation technique in the care of spinal injuries.
