Long-Term Reliability and Validity of the AO Spine PROST (Patient-Reported Outcome Spine Trauma)
Study Design.
Cross-sectional validation study.
Objective.
The aim was to validate the AO Spine Patient-Reported Outcome Spine Trauma (PROST) at a minimum of 12 months posttrauma and to evaluate patient characteristics, types of spine fractures, and treatment strategies as determinants of AO Spine PROST scores.
Summary of Background Data.
The reliability and validity of the AO Spine PROST as a measure of health-related quality of life for more than 12 months after onset of spine trauma is unclear.
Materials and Methods.
Patients with a traumatic spine injury were recruited from a level-1 trauma cen...

Extradural Contralateral Ventral Root Transfer to Treat Lower Limb Motor Dysfunction in Paraplegia
Conclusion.
Our study confirmed the anatomical feasibility of transferring the VRs of T11 to L2 and that of L1 to L3 to restore lower limb function in cases of hemiplegia.

A Cadaver Feasibility Study of Extradural Contralateral C7 Ventral Root Transfer Technique for Treating Upper Extremity Paralysis
Study Design.
A total of 6 formalin-fixed cadavers were included in the cadaver feasibility study.
Objective.
The aim was to ascertain the anatomical feasibility of extradural contralateral C7 ventral root transfer technique by cervical posterior.
Summary of Background Data.
Upper limb spastic hemiplegia is a common sequela after stroke. In our previous study, the authors established a method by transferring contralateral C7 dorsal and ventral roots to the corresponding C7 dorsal and ventral roots on the affected side in the cervical posterior.
Methods.
In the present study, six formalin-fixed cada...

Persistently Raised Serum Titanium Levels After Spinal Instrumentation in Children
Study Design.
Prospective study of patients undergoing elective spinal deformity surgery with repeated testing for circulating metal ions including preoperative levels acting as controls.
Objective.
The aim was to determine if levels of particular circulating metal ions are maintained to two years postsurgery including different implant systems and rods.
Summary of Background Data.
Adults having hip replacements, especially metal-on-metal bearings, may develop high metal ion levels. Pediatric spinal implants are known to cause circulating metal ions, notably titanium, chromium, cobalt, and nickel.

In Vivo Evidence of Early Instability and Late Stabilization in Motion Segments Immediately Superior to Anterior Cervical Arthrodesis
Conclusions.
Preexisting adjacent segment disc degeneration, as indicated by disc height and disc bulge, was associated with reduced adjacent segment motion after ACDF, while lack of preexisting adjacent disc degeneration was associated with increased adjacent segment motion after ACDF. These findings provide in vivo evidence supporting early instability and late stabilization in the pathophysiology of disc degeneration. (Source: Spine)

A Novel Grading System of Destructive Lumbar Spondyloarthropathy Based on Evaluation of the Facet Joints
Study Design.
Retrospective cohort study.
Objective.
To develop and evaluate a new grading system for destructive lumbar spondyloarthropathy (DLSA) by assessing bony destruction of the facet joints; to evaluate interrater reliability; and to determine the association between anteroposterior (AP) dural sac diameter at the lumbar level and the new grading.
Summary of Background Data.
The characteristics of DLSA are unknown, hindering clinical care and research. Imaging to determine the cause of DLSA may positively contribute to patient outcome or well-being by providing prognostic information.
Patients a...

Preoperative MRI Reliably Predicts Pedicle Dimensions on Intraoperative CT Images in Structural Main Thoracic Curves in Patients With Adolescent Idiopathic Scoliosis
Conclusion.
Pedicle measurements made on pMRI may be used with reasonable reliability to predict pedicle dimensions visualized on iCT, allowing surgeons to preoperatively plan pedicle screw sizes based off magnetic resonance imaging. (Source: Spine)

Biomechanical Assessment of Fracture Loads and Patterns of the Odontoid Process
This study aimed to investigate the biomechanical competence and fracture characteristics of the odontoid process.
Summary of Background Data.
Odontoid fractures of the second cervical vertebra (C2) represent the most common spine fracture type in the elderly. However, very little is known about the underlying biomechanical fracture mechanisms.
Materials and Methods.
A total of 42 C2 human anatomic specimens were scanned via computed tomography, divided in six groups, and subjected to combined quasistatic loading at −15°, 0°, and 15° in sagittal plane and −50° and 0° in transverse plane until fractur...

Step Count in Patients With Lumbar Spinal Stenosis: Accuracy During Walking and Nonwalking Activities
Conclusion.
The ankle-worn accelerometer provided the most accurate step count, but wrongly registered steps during nonwalking activities. The developed step detection method shows potential as a measure of walking activity why further development and testing under free-living conditions should be performed. (Source: Spine)
