STUDY DESIGN: Retrospective analysis of 16 patients. SUMMARY OF BACKGROUND DATA: The lumbar split fracture-dislocation is a rare but severe injury, which is type C1.2.1 fracture in the Association for the Study of Internal Fixation spine fracture classification. The axial compressive and torsional force shattered the vertebral body into 2 halves and displaced them rotationally. This kind of fracture is so highly unstable that the treatment is very challenging. PURPOSE: The purpose of this study was to report and compare on clinical outcome and complications of patients with lumbar split fracture-dislocation which had been treated either short-segment or long-segment posterior fixation and anterior fusion...

BACKGROUND: Ossification of posterior longitudinal ligament (OPLL) can be treated by two surgical strategies, anterior decompression with fusion and posterior decompression with laminoplasty or laminectomy. It has been debated which surgical approach is more appropriate for the treatment of multilevel OPLL. The purpose of this study is to compare the outcomes of anterior corpectomy surgery to posterior decompression surgery for the treatment of multilevel ossification of OPLL. MATERIALS AND METHODS: The databases of Medline, Embase, Pubmed, Cochrane library, and Cochrane Central Register of Controlled Trials was searched and we included trials which comparing anterior to posterior surgery for multilevel OPLL...

Yi Yang, Litai Ma, Lingli Li, Hao Liu
RATIONALE: Primary leiomyosarcoma of the bone was firstly reported by Evans and Sanerkin in 1965, whereas primary leiomyosarcoma of the vertebra is extremely rare. Because of the rarity of primary vertebral leiomyosarcoma, the diagnosis, treatment, and clinical outcome still remain controversial. Here we report a special case of primary leiomyosarcoma in the thoracic vertebra. PATIENT CONCERNS: A 47-year-old female patient was admitted to our institution with the chief complaint of persistent back pain for 4 weeks...

Giant schwannomas are defined as intradural extramedullary tumors that span >2 vertebral body lengths. Although uncommon, these lesions can cause significant mass effect on the spinal cord and subsequent neurologic compromise. Gross total resection is the goal of operative intervention, however, is extremely challenging in cases where the tumor occupies a ventral, midline position within the lower cervical thecal sac. Using a representative case presentation, we describe an adult male with insidious progression of upper extremity radicular pain and paresthesias, found to have a ventral, solid/cystic C5-C7 giant schwannoma...

BACKGROUND: Subsidence and late fusion are commonly observed in anterior subtotal corpectomy and reconstruction for treating thoracolumbar burst fractures. The subsidence rate of this surgical method was reported from 19.6% to 75% in the literatures, which would cause treatment failure. Thus, an improvement of anterior surgery technique should be studied to reduce these complications. MATERIALS AND METHODS: 130 patients of thoracolumbar burst fractures treated by minimal corpectomy, decompression and U cage, between January 2009 and December 2010 were included in this study...

The bilateral sagittal split mandibular osteotomy (BSSMO), a common maxillofacial technique for expanding the oropharynx during treatment of micrognathia, is a rarely employed but useful adjunct to improve surgical access to the ventral cervical spine in children. Specifically, it provides enhanced exposure of the craniocervical junction in the context of midface hypoplasia, and of the subaxial cervical spine in children with severe kyphosis. The authors describe their technique for BSSMO and evaluate long-term outcomes in patients...

Anterior cervical intradural arachnoid cyst is a rare entity which has been mostly approached posteriorly, commonly resulting in incomplete resection. Incomplete resection is associated with recurrence; hence, we describe the anterior central corpectomy approach with complete neurologic recovery in a twenty year old with an anterior cervical intradural arachnoid cyst in front of the third and fourth cervical vertebra, who had presented with spastic quadriparesis.

Kern H Guppy, James W Silverthorn
BACKGROUND: Spinal cord herniation (SCH) is rare, is mostly idiopathic, and occurs predominantly in the thoracic spine. SCH is less common in the cervical spine and has been reported after posterior cervical spine surgery associated with the development of pseudomeningoceles. Two cases of SCH have been reported after anterior cervical corpectomies for ossified posterior longitudinal ligament with cerebrospinal fluid (CSF) leaks. We report the third such case, but the first in a patient without ossified posterior longitudinal ligament (degenerative disc disease and pseudarthrosis)...

STUDY DESIGN: Biomechanical investigation. PURPOSE: Cervical two-level corpectomies with anterior-only instrumentation are associated with a high rate of implant-related complications. These procedures, therefore, often require an additional dorsal instrumentation to prevent screw loosening. Cement augmentation of the anterior screws in two-level corpectomies might stabilize the construct, so that a second dorsal procedure could be avoided. To evaluate the screw anchorage in cervical anterior-only procedures, an ex vivo evaluation of the range of motion (ROM) in two-level corpectomies (C4 and C5), with and without cement augmentation of the anterior screws, was carried out in this study...

BACKGROUND: Cervical spondylotic myelopathy is caused by cervical stenosis. Several techniques have been described for the treatment of multilevel disease, such as the anterior corpectomy with titanium mesh cage and anterior cervical plate placement, which has the advantage of performing a wider decompression and using the same bone as graft. However, it has caused controversy since the collapse of the mesh cage continues being a major limitation of this procedure. MATERIAL AND METHOD: A prospective 4-year follow-up study was conducted in 7 patients diagnosed with cervical stenosis, who were treated surgically by one level corpectomy with titanium mesh cage and anterior cervical plate placement, evaluating them by radiographs and clinical scales...

Luigi La Barbera, Tomaso Villa
Mechanical reliability tests on posterior spine stabilization devices are based on standard F1717 by the American Society for Testing and Materials, which describes how to assemble the implant with vertebrae-like test blocks in a corpectomy model. A recent study proposed to revise the standard to describe the anatomical worst-case scenario, instead of the average one currently implemented, and introduce the unsupported screw length as a mechanical parameter. This article investigates the implications of such revisions on the endurance properties of an implant already on the market...

Background Anterior cervical corpectomy and fusion (ACCF) has become a standard procedure for patients with spondylotic myelopathy due to multisegmental stenosis of the cervical canal. Beside the fusion technique using autogenous bone grafts, synthetic cages have been increasingly used in recent years. Published information on the clinical and radiological results of different cage materials for ACCF is still limited. The study presented here is the largest series to date reporting clinical and radiological outcomes and complication rates after one- to three-level ACCF using structural polyetheretherketone (PEEK) or titanium cages augmented by anterior plate-screw osteosynthesis...
