Comparative Study
Cross-sectional area of the posterior extensor muscles of the cervical spine in whiplash injury patients versus healthy volunteers--10 year follow-up MR study.
Long-term follow-up studies focusing on the posterior extensor muscles in patients suffering from whiplash injury are scarce. The purpose of this study was to elucidate the changes in the posterior extensor muscles 10 years after whiplash injury. ⋯ There was no significant difference in the change in CSA between whiplash patients and healthy volunteers after a 10-year follow-up period. In both groups, the cross-sectional area slightly increased at follow-up. In addition, there was no association between the change in CSA and clinical symptoms such as neck and shoulder pain. These results suggest that whiplash injury is not associated with symptomatic atrophy of the posterior cervical muscles over the long term.

Randomized Controlled Trial
Computer navigation in the reduction and fixation of femoral shaft fractures: a randomized control study.
We investigated the accuracy of reduction of intramedullary nailed femoral shaft fractures in human cadavers, comparing conventional and computer navigation techniques. ⋯ Computer navigation significantly improves the accuracy of femoral shaft fracture fixation with regard to leg length, but not rotational deformity.

Successful treatment of intertrochanteric femoral fractures was reportedly influenced by the position of the fixation devices, by reduction quality and by fracture type. ⋯ The TAD scale focuses on length measurement and lacks the vector properties of multidirectional measurements. Vector analysis revealed that the caudal-cranial correct lag screw position is the most important factor in preventing mechanical failure.

By analysing the injuries of the orthopaedic wounded during the 2010 Yushu earthquake, we aim to provide useful medical information for the rational application and allocation of medical resources and better implementation of medical relief in earthquake-stricken areas. ⋯ The patients who experienced fractures in the Yushu earthquake were mostly adults. This was correlated with population composition in Yushu area. This time all the orthopaedic injuries were relative mild with less complication as nerve injury or crush syndrome mainly because of the characteristics of the house structure in Yushu area.

Case Reports
Percutaneous cerclage wiring for reduction of periprosthetic and difficult femoral fractures. A technical note.
Combining closed reduction techniques with minimally invasive plate osteosynthesis (MIPO) or intramedullary nailing is a technically challenging procedure, especially when dealing with complex femoral fractures such as periprosthetic fractures. Cerclage wiring is a well known adjunct for fracture reduction and fixation. However, it is usually performed by open reduction, requiring wide surgical exposures, that results in soft tissue stripping. ⋯ Percutaneous wiring is an alternative reduction technique to facilitate the reduction and maintenance of difficult femoral fractures, which reduces the radiation exposure to the surgeon.
