}Study Design. A biomechanical study using a cadaver model was conducted to define the function of the nuchal ligament in the restraint of flexion of the cervical spine. Objective. To test the hypothesis that surgical resection of the nuchal ligament significantly reduces the structural restraints to cervical flexion. Summary of Background Data. Although previous studies have examined the role of the posterior ligaments and capsules on cervical stability, no prior study has quantified the…

Biomechanical Analysis of Posterior Ligaments of Cervical Spine and Laminoplasty
- MedicineApplied Sciences
- 2021
The C2–C7 cervical spine finite element model and simulated C3–C6 double-door laminoplasty were developed and the range of motion (ROM), intervertebral nucleus stress, and facet contact forces were analyzed under flexion/extension, lateral bending, and axial rotation.

Cervical Laminoplasty: The History and the Future
- MedicineNeurologia medico-chirurgica
- 2015
Cervical laminoplasty was developed as an alternative to cervical laminectomy for treatment of cervical myelopathy, in which hinges are created to lift the lamina, but is rarely performed in the United States and Europe.
Morphometrics of nuchal ligament in greyhound in different neck and body positions

- 2021
It is suggested that different neck and body positions change the shape, and hence, the function of the nuchal ligament during movement.
Radiographic analysis of the correlation between ossification of the nuchal ligament and sagittal alignment and segmental stability of the cervical spine in patients with cervical spondylotic myelopathy
- MedicineActa radiologica
- 2019
Patients with ONL are more likely to have abnormal sagittal alignment and instability of the cervical spine, and increased awareness and appreciation of this often-overlooked radiographic finding is warranted during diagnosis and treatment of instability-related cervical pathologies and injuries.
Preservation of the Nuchal Ligament Plays an Important Role in Preventing Unfavorable Radiologic Changes After Laminoplasty
- MedicineJournal of spinal disorders & techniques
- 2008
Results indicate that the preserved funicular section of the nuchal ligament attached both to the C6 and C7 spinous processes plays an important role in preventing undesirable radiologic changes after laminoplasty.
Flexion-Distraction Injuries of the Subaxial Cervical Spine
- Medicine
- 2013
Flexion-distraction injuries are among the most common mechanisms for subaxial cervical trauma and functional and neurological status can improve, particularly after operative intervention, but affect patient's health-related quality of life and outcome long after the injury.
Transverse Process Hooks at Upper Instrumented Vertebra Provide More Gradual Motion Transition Than Pedicle Screws
- MedicineSpine
- 2014
TPHs at the upper instrumented vertebra may be postulated to decrease the incidence of postoperative proximal junctional kyphosis compared with APS.
Can Laminoplasty Maintain the Cervical Alignment Even When the C2 Lamina Is Contained?
- MedicineSpine
- 2005
The cervical alignment deteriorated significantly in S group compared with the I group, and if laminoplasty included the C2 lamina, the alignment worsened, and there was no significant correlation with the postoperative upper and lower m-JOA scores or score change.
The Correlation Between Ossification of the Nuchal Ligament and Pathological Changes of the Cervical Spine in Patients With Cervical Spondylosis
- MedicineSpine
- 2014
The location of ONL commonly corresponds to the most stenotic level of the spinal canal, which correlates with the level of osteophyte formation and intervertebral disc degeneration, indicating that ONL has correspondence to instability-related cervical pathological changes in cervical spondylosis.

Biomechanical Alterations Induced by Multilevel Cervical Laminectomy
- Medicine, BiologySpine
- 1995
Multilevel cervical laminectomy induces significant increases in total column flexibility associated with increased segmental flexural sagittal rotations, which may constitute part of the underlying basis for failure of laminationectomy to offer sustained good therapeutic results of the myelopathy associated with cervical stenosis and cervical spondyloarthropathy.
Tension-band laminoplasty of the cervical spine

A new laminoplasty of the cervical spine has been developed using preserved ligaments as a tension-band and allows better function of the neck and more new bone formation around the spacers.
A Biomechanical Comparison of Cervical Laminaplasty and Cervical Laminectomy with Progressive Facetectomy
- MedicineSpine
- 1993
Patients undergoing cervical laminaplasty accompanied by more than 25% bilateral facetectomy, concurrent arthrodesis should be performed, because as little as 25% facetectomy adversely affects stability after multilevel cervical laminectomy.
Biomechanical Evaluation of Cervical Double-Door Laminoplasty Using Hydroxyapatite Spacer
- MedicineSpine
- 2003
Double-door laminoplasty with hydroxyapatite spacer appears to restore the motion of the decompressed segment back to its intact state in all loading modes, and seems to have potential leading postoperative deformity or instability.
Cyclic Compression‐Flexion Loading of the Human Lumbar Spine

The data suggest that the fatigue response can be understood by cyclically loading the ligamentous lumbar spine prepartion to approximately 2,000 cycles.
Anterior cervical plating reverses load transfer through multilevel strut-grafts.

- 2000
Anterior multilevel cervical plating effectively increases stiffness and decreases local cervical motion after corpectomy, but also reverses graft loads and excessively loads the graft in extension, which may promote pistoning and failure of multileVEL constructs.
Cervical Stability After Sequential Capsule Resection

Significant hypermobility did occur during both torsion and flexion testing with greater than 50% resection of the facet capsules, and great care should be taken when exposing an unfused facet to limit facet-capsule resection to less than 50%.
