Study Design:Expert opinion.Objectives:Osteoporotic vertebral fractures are of increasing medical importance. For an adequate treatment strategy, an easy and reliable classification is needed.Methods:The working group “Osteoporotic Fractures” of the Spine Section of the German Society for Orthopaedics and Trauma (DGOU) has developed a classification system (OF classification) for osteoporotic thoracolumbar fractures. The consensus decision followed an established pathway including review of the current literature.Results:The OF classification consists of 5 groups: OF 1, no vertebral deformation (vertebral edema); OF 2, deformation with no or minor (<1/5) involvement of the posterior wall; OF 3, deformation with distinct involvement (>1/5) of the posterior wall; OF 4, loss of integrity of the vertebral frame or vertebral body collapse or pincer-type fracture; OF 5, injuries with distraction or rotation. The interobserver reliability was substantial (κ = .63).Conclusions:The proposed OF classification is easy to use and provides superior clinical differentiation of the typical osteoporotic fracture morphologies.

The reinforcement of pedicle screws using PMMA augmentation may be a viable option in the surgical treatment of spinal fractures in the elderly.

This novel classification may improve communication between spine surgeons and radiologists as well as facilitate clinical decision making in spine surgery. Further studies need to be conducted to verify clinical relevance.

PurposeThis study aims to investigate the effect of authentic leadership and psychological capital (PsyCap) on work engagement via job satisfaction by employing the job demands-resources (JD-R) model.Design/methodology/approachParticipants were 307 (52% male and 48% female) employees randomly recruited from a state-owned company in the eastern part of Indonesia. Most participants had completed an undergraduate degree with a mean age of 27.55 (SD = 7.89). The study employed a three-wave data collection technique to rule out any common method biases.FindingsThe results suggested that the theoretical model and empirical data showed a good fit (CMIN/DF = 2.19 and RMSEA = 0.06), indicating an indirect effect of authentic leadership and PsyCap on work engagement via job satisfaction. The effect of authentic leadership on work engagement was fully mediated by job satisfaction. In contrast, job satisfaction only partially mediated the relationship between PsyCap and work engagement.Research limitations/implicationsFirst, this study did not explore any further consequences of gender equality. Second, although the data have been compared with some existing studies, this study did not collect cross-cultural data from different countries. Lastly, the data were collected from a state-owned enterprise, which may limit generalisation to other organisations.Originality/valueThis study offered a new perspective by examining the implications of the JD-R model in the eastern part of Indonesia, where organisation culture is predominantly influenced by Buginese values. Furthermore, the inclusion of job satisfaction into the model added new information regarding the importance of mediating variables in explaining the indirect effect of job and personal resources.

Injury to the spinal column and cord are often part of life-threatening multiple trauma. Epidemiological data could help to establish an evidence-based assessment and therapy of these patients. We present a retrospective chart analysis of 590 multiple traumatized patients admitted within a 4-year-period. Patients suffering from injuries of the spinal column were analysed regarding mechanism and distribution of their injuries to all body regions. Thirty-one percent (n = 183) of polytraumatized patients displayed a spine injury. Distribution analysis showed peaks in the cervical spine and the thoraco-lumbar junction. The risk of relevant associated injuries is mainly influenced from anatomical vicinity to the injured spinal segment. Injuries to the spinal column are frequent in the multiple trauma patients population. Diagnosed injuries to distinct body regions should make the trauma team suspicious of injury to the nearby spinal column. Appropriate treatment includes thorough assessment of all injuries to clarify the damage and carry on special protection of these spinal regions preventing from deterioration.
