We tested the hypothesis that whiplash trauma leads to changes of the signal intensity of cervical discs in T2-weighted images. ⋯ We could not find any trauma related changes of cervical disc signal intensities. Normalized signals of discs and Pfirrmann grading changed with age and varied between disc levels with the used MR sequence.

Additional anterior plating enhances fusion in anteroposteriorly stabilized thoracolumbar fractures.
To prospectively evaluate the potential radiological and clinical effect of the additional application of an anterior plate in anteroposteriorly stabilized thoracolumbar fractures. ⋯ Additional anterior plating in anteroposteriorly stabilized thoracolumbar fractures leads to significant faster fusion but does neither influence reduction loss nor cage subsidence. The anterior plate serves as a pathway for bone growth and increases biomechanical stability, resulting in a higher fusion rate.

The epidemiology of paediatric supracondylar fracture (SCF) fixation has not been evaluated at a population level. The purpose of this study was to: (1) determine the incidence density rate (IDR) of SCF fixation and (2) determine the rate of and risk factors for re-operation. ⋯ While SCF fixation is common, the rate of re-operation is low. No differences existed between the sexes and a higher volume of fixations occurred during the summer months.

Percutaneous reduction and periarticular screw implantation techniques have been successfully introduced in acetabular surgery. Image guided navigation techniques might be beneficial in increasing accuracy. However, a thorough understanding of standard values is needed to oversee pitfalls. ⋯ The findings provide standard values for safe passages in percutaneous posterior column acetabular surgery. Gender differences have to be taken in consideration when planning the drill corridor. By adherence to standard values, screw placement can be performed safely.

Comparative Study
Locked versus standard unlocked plating of the symphysis pubis in a Type-C pelvic injury: A cadaver biomechanical study.
The benefits of locked plating for pubic symphyseal disruption have not been established. The purpose of this biomechanical study was to determine whether locked plating offers any advantage over conventional unlocked plating of the pubic symphysis in the vertically unstable, Type-C pelvic injury. ⋯ Pubic symphyseal locked plating does not appear to offer any advantage over standard unlocked plating for a Type-C (OTA 61-C1.2) pelvic ring injury.
